科士达UPS电源的10大基本问题

科士达UPS电源也就是在市电停电时候能继续向用电设备提供不间断电源的一种装置,保证设备能正常工作。随着信息化社会的来临，科士达UPS电源广泛地应用于从信息采集、传送、处理、储存到应用的各个环节，其重要性是随着信息应用重要性的日益提高而增加的。

今天，我们就来盘点一些最经常见的问题:

1、科士达UPS电源一般哪种负载的能力强?

一般科士达UPS电源就是按感性负载设计的，所以带感性负载是它的本分。一般科士达UPS电源逆变器输出端并联的电容器一方面起滤波作用，另一方面是抵消负载中的电感分量。

如果负载时容性，又如何用电容去抵消电容性分量呢?只能使输出的电容分量加大，而这些电容分量的电流又必须由逆变器提供，使逆变器输出的有功分量减小，所以带载的能力就减弱了。

2、STS、LBS及双总线作用是什么?

STS(静态开关)的作用是将两路输入交流电进行切换。LBS(同步器)的作用是将两组科士达UPS电源同步，目的是为了使STS的切换时间为零。双总线的作用是为了给用电设备提供冗余的电源。

3、科士达UPS电源工频机和高频机比较有什么优缺点?

工频机科士达UPS电源：缺点是输入功率因数低，功耗大，效率低，体积大，笨重，价格高，可靠性低;优点是制造相对容易，尤其是采用手工作业影响也不大，要求一致性相对低一些。

高频机科士达UPS电源：优点是输入功率因数高，功耗小，效率高，体积小，轻便，可靠性高;但对生产手段要求高，要求一致性严格。

Costa UPS power supply is a device that can continue to provide uninterruptible power supply to electrical equipment during power outage in the city, so as to ensure the normal operation of the equipment. With the advent of information society, Kosta UPS power supply is widely used in all aspects of information acquisition, transmission, processing, storage and application. Its importance is increasing with the increasing importance of information application.
Today, let's take stock of some of the most common problems:
1. What kind of load is the capacity of COSTAR UPS power supply strong?
Usually, the Corstal UPS power supply is designed according to the inductive load, so the inductive load is its part. Generally, the output capacitors of Kosta UPS power supply inverters are connected in parallel. On the one hand, they act as filters, on the other hand, they cancel the inductance component in the load.
If the capacitance of load is capacitive, how to use capacitance to offset the capacitive component? Only the output capacitive component can be increased, and the current of these capacitive components must be provided by the inverter, so that the active component of the output of the inverter can be reduced, so the carrying capacity will be weakened.
2. What are the functions of STS, LBS and dual bus?
The function of STS (static switch) is to switch two input AC lines. The function of LBS (Synchronizer) is to synchronize the two groups of Corstal UPS power supply in order to make the switching time of STS zero. The function of dual bus is to provide redundant power for electrical equipment.
3. What are the advantages and disadvantages of Kosta UPS power supply between power frequency machine and high frequency machine?
Power Frequency Machine Costa UPS Power Supply: The shortcomings are low input power factor, high power consumption, low efficiency, large volume, heavy, high price, low reliability; the advantages are relatively easy to manufacture, especially the impact of manual operation is not large, the requirements of consistency are relatively low.
High Frequency Machine Costa UPS Power Supply: Its advantages are high input power factor, low power consumption, high efficiency, small size, light weight and high reliability, but it requires high production means and strict consistency.

4、为什么科士达UPS电源容量用VA表示?叫什么功率?

有功功率的单位是瓦特(W)，无功功率的单位是乏(var)。一般UPS的容量都用视在功率表示，由于视在功率中既包含有功功率，也包含无功功率，既不能称作W也不能称var，既然是视在功率是伏特(V)与安培(A)，就索性称为VA。

5、科士达UPS电源上有防雷吗?

科士达UPS电源可以选配输入C级防雷，它有两种方式：以保护负载为优先的防雷;以保护供电为优先的防雷，但是作用不大。因为科士达UPS电源装了防雷充其量只能使配电柜中省一级防雷，但是配电当中还是不能省略防雷装置。

6、了解科士达UPS电源发展情况对用户有何好处?

了解科士达UPS电源发展的方向最主要的目的是使用户避免购买已经过时而已被淘汰或马上就被淘汰的设备，以免造成不必要的损失。目前科士达UPS电源已经发展到了在线式并联冗余模块化解决方案系统UPS，请渠道商和用户都能认识到模块化已经来临，它将取代传统科士达UPS电源在数据机房的应用。

7、科士达UPS电源工频机输出隔离变压器是否全隔离效果?

工频机的输出隔离变压器严格讲是它逆变部分不可或缺的组件，没有全隔离效果，因为旁路无隔离，零线无隔离。

8、科士达UPS电源的发展趋势是怎样的?

发展科士达UPS电源技术的主要目的是提高UPS对输出端负载的动态响应越来越快又好。UPS在未来更加智能化、网络化、绿色化、高频化。

9、科士达UPS电源效率定义是什么?它代表什么?

科士达UPS电源效率的η的定义是：输出有功功率P与输入有功功率P’之比的百分数，即：η=(P/P’)%。它是衡量UPS功耗大小的标志。和功率因数不是一码事。

10、存能科士达UPS电源可靠吗?

存能电气从事锂电池科士达UPS电源行业多年，沉淀了丰富的专业经验，深谙UPS不间断电源在通讯、电力等行业的应用和锂电池科士达UPS电源行业现状及特点，洞悉行业发展趋势，为广大用户提供稳定、安全、便携的产品及完美的电力能源解决方案。

Why is the power capacity of Kosta UPS expressed in VA? What power is it called?
The unit of active power is W, and the unit of reactive power is var. Generally, the capacity of UPS is expressed by apparent power. Since apparent power includes both active power and reactive power, it can neither be called W nor var. Since apparent power is volt (V) and ampere (A), it is called VA.
5. Are there lightning protection on Kosta UPS power supply?
Corstal UPS power supply can be selected to input Class C lightning protection, which has two ways: lightning protection with priority to protect load; lightning protection with priority to protect power supply, but has little effect. Because Kosta UPS power supply is equipped with lightning protection, at best, it can only make the distribution cabinet provincial level one lightning protection, but the lightning protection device can not be omitted in distribution.
6. What are the benefits for users to understand the development of UPS power supply in Costa?
Understanding the direction of Corstal UPS power supply development is the most important goal to prevent users from buying out-of-date or immediately obsolete equipment, so as to avoid unnecessary losses. Currently, Corstal UPS power supply has developed to the online parallel redundancy modular solution system UPS. Channel vendors and users can realize that modularization has come, which will replace the traditional Corstal UPS power supply in the data room application.
7. Is the output isolation transformer of Kosta UPS power supply full isolation effect?
Strictly speaking, the output isolation transformer of the power frequency machine is an indispensable component of its inverters. It has no full isolation effect, because there is no isolation in bypass and no isolation in zero line.
8. What is the development trend of Corstal UPS power supply?
The main purpose of developing Kosta UPS power supply technology is to improve the dynamic response of UPS to output load faster and better. UPS will become more intelligent, networked, green and high-frequency in the future.
9. What is the definition of the power efficiency of Kosta UPS? What does it represent?
The definition of_of COSTAR UPS power supply efficiency is: the percentage of the ratio of output active power P to input active power P', i.e. _= (P/P')%. It is a symbol to measure the power consumption of UPS. And power factor is not the same thing.
10. Is the UPS power supply reliable?
Energy Storage Electric has been engaged in the lithium battery Corstal UPS power supply industry for many years, and has accumulated rich professional experience. It is well versed in the application of UPS in communication, power and other industries, and the current situation and characteristics of the lithium battery Corstal UPS power supply industry. It has a good insight into the development trend of the industry and provides stable, safe, portable products and perfect power energy solutions for the majority of users.

更换科士达UPS电源蓄电池的方法和步骤：

1、接到可对电池进行更换工作的通知后，电池更换实施工程师到现场进行准备工作：确保科士达UPS电源主机的输入供电、新旧蓄电池的登记检查、机房内消防系统烟雾探头的密封、准备二氧化碳灭火器等相关工作。更换电池前对科士达UPS电源主机、旧电池组、电池监测仪等设备做好相关的登记记录，特别是每层电池的摆放、电池监测仪的接线，要做好标记，画好联接图。保证电池组更换后的效果和原有的情况保持一致。

2、一切准备就绪后，科士达UPS电源主机的电池进行更换处理工作，断开科士达UPS电源主机和电池组之间的连接开关，使科士达UPS电源主机和电池组断开联接，确保更换电池时工作人员的安全。对原有电池组的电池进行拆卸，电池更换实施工程师负责电池拆卸工作，相关辅助技术人员进行新旧电池的搬运工作。在拆旧电池时，将拆卸下来的电池连接线和电池端子的螺丝用盒子整齐的摆放好，保证机房内的整洁和清洁。旧电池拆完后，将旧电池和旧电池架整齐的摆放在甲方规定的位置。将新电池架组装件安放在制定位置，同时开始安装新电池，将新电池摆放在电池架上，使新电池在电池架上的摆放位置、方向调整的最好。在连接好一组电池后检查电池端子的连接线是否牢固;检查电池组的总电压是否正常等情况，电池的正负极要连接正确。

3、更换电池工作完毕后，用万用表检查电池组的总电压情况、电池组的正负极和中性线的接线情况。确保电池组和科士达UPS电源主机都正常后，合闭电池组的开关，使科士达UPS电源系统恢复正常工作。然后检测科士达UPS电源的工作电压、电流、充电电压、工作状态等情况并做好记录。由一人观察主机液晶显示屏里面的参数和实际的是否一致，电池时间参数进行调试设置，确保电池在正常的寿命期间不会出现错误的报警提示。科士达UPS电源主机调试正常后，断开科士达UPS电源主机的输入电源开关，模拟市电故障中断，测试科士达UPS电源系统是否能正常由市电转为电池组后备电源供电，确保机房机柜内的设备正常运行。在电池更换工作完成之后，对科士达UPS电源房进行打扫清洁，清理杂物，保证科士达UPS电源房的良好环境。恢复电池更换之前，机房内所做的准备工作。而且应使新电池组充电至24小时左右，确保新电池充满电量。

一直以来,业界对工频科士达UPS电源和高频科士达UPS电源的概念有各种定义,给用户造成了不少混淆。主要的定义方法有以下两种:一是逆变器调制频率论。即逆变器调制频率高于20kHz的UPS称为高频UPS,低于这个频率的UPS称为工频科士达UPS电源。这种定义方式经不起推敲的地方在于,如果以逆变器调制频率来定义,那么不仅应该有高频UPS,还应该有中频UPS。而“工频UPS”的说法就师出无名了,因为,目前UPS的逆变器调制频率大多为4～8kHz,根本没有以工频(50Hz)来调制的。二是整流器调制频率论。这也是最为普遍被接受的一种定义方法。即如果整流器是工频整流(如晶闸管整流),则称为工频机,否则称为高频机。这种定义方法,在一段时间内确实为业内外普遍接受。但随着UPS技术的发展,这种定义方法也显现出了其不严谨的地方,无法对现有的UPS机型进行准确分类。

只有从科士达UPS电源的拓扑结构上,才能对两类UPS进行准确分类。从拓扑结构上可以看到,两类UPS的最大区别在于升压环节的处理。带变压器的科士达UPS电源,通过变压器在逆变器后端进行交流升压;无变压器的UPS,通过直流斩波在逆变器前端进行直流升压。

The method and steps of replacing the battery of Corstal UPS power supply are as follows:
1. After receiving the notification of battery replacement, the battery replacement engineer will go to the scene to prepare for the work: to ensure the input and power supply of the UPS mainframe, the registration and inspection of new and old batteries, the sealing of smoke probes in the fire fighting system in the engine room, and the preparation of carbon dioxide fire extinguishers. Before replacing batteries, make relevant registration records for UPS mainframe, old batteries, battery monitor and other equipment, especially for the placement of batteries on each layer and the wiring of battery monitor. Make good marks and draw the connection diagram. Ensure that the effect of battery pack replacement is consistent with the original situation.
2. When everything is ready, the batteries of Kosta UPS mainframe will be replaced and handled. The connection switch between Kosta UPS mainframe and battery group will be disconnected, so that the UPS mainframe and battery group of Kosta can be disconnected to ensure the safety of staff when replacing batteries. The original battery pack is disassembled. The battery replacement and implementation engineer is responsible for the battery disassembly. Relevant assistant technicians carry out the work of new and old batteries. When dismantling old batteries, the dismantled battery connection wires and the screw of battery terminals are arranged neatly in boxes to ensure the cleanliness and cleanliness of the machine room. After the old batteries are dismantled, the old batteries and the old battery racks are neatly placed in the position prescribed by Party A. Place the new battery rack assembly in the designated position, and start installing new batteries. Place new batteries on the battery rack, so that the new batteries on the battery rack can be placed in the best position and direction adjustment. After connecting a group of batteries, check whether the connection wire of the battery terminal is firm; check whether the total voltage of the battery pack is normal, and so on, the positive and negative poles of the battery should be connected correctly.
3. After replacing the battery, check the total voltage of the battery pack, the connection of the positive and negative electrodes and the neutral wires of the battery pack with the multimeter. Ensure that the battery pack and the Corstal UPS mainframe are normal, then close the switch of the battery pack, so that the Corstal UPS power supply system can resume normal operation. Then, the working voltage, current, charging voltage and working status of the Corstal UPS power supply are detected and recorded. One person observes whether the parameters in the LCD screen of the host are consistent with the actual ones, and adjusts the battery time parameters to ensure that there are no wrong alarms during the normal life of the battery. After the UPS mainframe of Costa is debugged properly, the input power switch of the UPS mainframe of Costa is disconnected to simulate the interruption of the power failure. The power supply system of Costa UPS is tested whether it can be converted from the municipal power to the backup power supply of the battery unit to ensure the normal operation of the equipment in the cabinet of the computer room.  After the battery replacement work is completed, the UPS power supply room of Kosta is cleaned and debris is cleaned to ensure a good environment for the UPS power supply room of Kosta. Preparations made in the computer room before battery replacement is resumed. And the new battery pack should be charged to about 24 hours to ensure that the new battery is full of electricity.

For a long time, the industry has various definitions of power frequency Kosta UPS power supply and high frequency Kosta UPS power supply, which has caused a lot of confusion to users. There are two main definitions: one is the modulation frequency theory of inverters. That is to say, the UPS whose modulation frequency is higher than 20 kHz is called high frequency UPS, and the UPS whose modulation frequency is lower is called power frequency Corstal UPS. This definition can not withstand deliberation because if it is defined by the modulation frequency of the inverter, there should be not only high frequency UPS, but also intermediate frequency UPS. The term "power frequency UPS" is unknown, because most of the current UPS inverters are modulated at 4 to 8 kHz, and there is no power frequency (50 Hz) modulation at all. The second is the theory of modulation frequency of rectifier. This is also one of the most commonly accepted definitions. That is, if the rectifier is power frequency rectifier (such as thyristor rectifier), it is called power frequency machine, otherwise it is called high frequency machine. This definition method has been widely accepted both inside and outside the industry for some time. However, with the development of UPS technology, this definition method also shows its inaccuracy, which can not accurately classify the existing UPS models.
Only in terms of the topology of Kosta UPS power supply, can two types of UPS be classified accurately. From the topological structure, we can see that the biggest difference between the two types of UPS is the processing of boost link. Corstal UPS power supply with transformer, AC boost through transformer at the back end of the inverter; UPS without transformer, DC boost through DC chopper at the front end of the inverter.

因此,依照上述原则,如果一定要使用高频或工频的概念进行分类,那么更准确的高频机或工频机的定义是:通过高频直流斩波升压的科士达UPS电源称为高频机;通过逆变器输出变压器进行交流升压的UPS称为工频机。

所以,一台高频机即使外加了输出变压器也不应称为工频机,因为此变压器没有升压作用;而一台工频UPS即使采用IGBT整流也不应称为高频机,因为其升压环节是变压器。

通常情况下，科士达UPS电源系统带有隔离变压器可分为：输入端，输出端和旁路端。其特性是具有电压变换功能和滤波抗干扰功能。

隔离变压器在科士达UPS电源输入端及交流电源的特点：若电网三次谐波和干扰信号比较严重，采用隔离变压器，可以去掉三次谐波和减少干扰信号;采用隔离变压器可以产生新的中性线，避免由于电网中性线不良造成设备运行不正常;非线性负载引起的电流波形畸变(如三次谐波)可被隔离而不污染电网。

隔离变压器在科士达UPS电源输出端及交流电源的特点：防止非线性负载的电流畸变影响到交流电源的正常工作及对电网产生污染，起到净化电网的作用;在隔离变压器输入端采样,使得非线性负载电流的畸变不影响取样的准确性，得到能反应实际情况的控制信号;若负载不平衡，也不影响稳压电源的正常工作。

从专业的角度说，看一台科士达UPS电源的好与不好，最客观和最可靠的方法就是用测试指标去衡量。

就拿影响电网供电质量的输入功率因数来说，尤其是在大容量范围时，一般传统双变换型科士达UPS电源的标配功率因数大都在0.8左右，这就造成了约有30%的谐波电流对电网的*，其结果是使该电网上的变压器、电缆、保险丝和开关等设备发热、疲劳。若要改变这种状况就必须在前面加谐波滤波器或改6脉冲整流为12脉冲整流，但这又会带来两个副作用：一个是增加包括科士达UPS电源在内的电源保护设备的成本和体积重量，另一方面增加了科士达UPS电源的损耗，从而降低了可靠性。

又如科士达UPS电源的工作效率，这是一个直接与可靠性相关联的指标。一般传统双变换型UPS由于其电路结构所限，很难将效率做高，尤其是在加入功率因数补偿设备后，就更难将效率做到92%以上。尽管这些UPS采用了ECO经济运行模式，可以将效率做到97%以上，但这种ECO经济运行模式由于它实际上是甩开了UPS的正常功能而采用了“旁路直接供电”方式，牺牲了稳压和抗*等UPS应有的基本功能，给用户的使用埋下了隐患，这无疑违背了使用科士达UPS电源的本来目的，因此极少被采用。

另外，带载和过载能力也是反映科士达UPS电源质量的关键指标，负载真正需要UPS起保护作用的时机莫过于两种情况：当电网电压异常或是负载异常时。在电网电压异常时(包括断电)，对负载的保护靠的是UPS输入电路和不间断功能，而负载异常时，对其保护则要靠UPS的带载和过载能力。一般传统双变换型科士达UPS电源的带载能力弱就是因为其负载功率因数的单一性，难于适应不同性质的负载。

科士达UPS电源组成部分

科士达UPS电源系统一般由UPS主机、旁路稳压柜、输出馈线柜等三部分组成(小功率时也可三合一)。

1、UPS主机柜：输入输出隔离变压器、整流器、逆变器、静态旁路开关、旁路开关、逆止二极管;

2、旁路隔离稳压柜：旁路隔离变压器、旁路稳压器、手动/旁路维修开关;

3、馈线柜：回路分配单元、监测仪表、控制开关及信号指示等;

UPS专用电源采用1+1的冗余供电系统，针对电力系统应用负载及环境，运用先进技术制造的工业级交流保护电源，能够充分满足电力DCS系统等负载对供电可靠性的要求。

UPS主要有以下几个系统组成，采用两级变换。第一级变换采用整流器(AC-DC)，

把经过输入隔离变压器后的交流电变成稳定的直流电。第二级变换(DC-AC)采用逆变电源，把整流后输出的直流电变换成正弦波交流电经过隔离输出给负载。

隔离部分：输入隔离变将交流输入和直流隔离开，保护直流侧设备;输出隔离变将交、直流输入与交流输出隔离开，保护负载端设备。双隔离保证了直流输入、交流输入与交流输出三个端口的真正完全的电气隔离。

Therefore, according to the above principles, if we must use the concept of high frequency or power frequency to classify, then the more accurate definition of high frequency machine or power frequency machine is: Corstal UPS power supply with high frequency DC chopper boost is called high frequency machine; UPS with AC boost through inverter output transformer is called power frequency machine.
Therefore, a high frequency machine should not be called a power frequency machine even if the output transformer is added, because this transformer has no boost effect; and a power frequency UPS should not be called a high frequency machine even if IGBT rectifier is used, because its boost link is a transformer.
Usually, Corstal UPS power supply system with isolation transformer can be divided into: input end, output end and bypass end. Its characteristic is that it has the function of voltage conversion and anti-interference filtering.
The characteristics of isolation transformer at the input end of UPS power supply and AC power supply in Costa Rica are as follows: if the third harmonic and interference signals of power grid are serious, the third harmonic and interference signals can be removed and reduced by using isolation transformer; new neutral lines can be generated by using isolation transformer to avoid abnormal operation of equipment caused by bad neutral lines of power grid; current waveform distortion caused by non-linear load;（ For example, the third harmonic can be isolated without polluting the power grid.

The characteristics of isolation transformer at the output end of UPS power supply and AC power supply in Costa Rica are as follows: to prevent the current distortion of non-linear load from affecting the normal operation of AC power supply and polluting the power grid, and to purify the power grid; to sample at the input end of isolation transformer, so that the distortion of non-linear load current does not affect the accuracy of sampling, and to obtain the control signal that can reflect the actual situation; if negative. The unbalanced load does not affect the normal operation of the regulated power supply.
From a professional point of view, the most objective and reliable way to see whether a Corstal UPS power supply is good or bad is to use test indicators to measure.
Take the input power factor which affects the quality of power supply in power grid, especially in large capacity range, the standard power factor of the traditional double-conversion Kosta UPS power supply is mostly about 0.8, which causes about 30% of harmonic current to the power grid*. The result is that transformers, cables, fuses and switches on the power grid are heated and fatigued. If we want to change this situation, we must add harmonic filter or change 6-pulse rectifier to 12-pulse rectifier in the front, but this will bring two side effects: one is to increase the cost and volume weight of power protection equipment including Corstal UPS power supply, and the other is to increase the loss of Corstal UPS power supply, thus reducing the reliability.
For example, the work efficiency of Kosta UPS power supply, which is an indicator directly related to reliability. Due to the limitation of circuit structure, it is difficult to improve the efficiency of traditional Dual-Transform UPS, especially when power factor compensation equipment is added, it is more difficult to achieve efficiency of more than 92%. Although these UPS adopt ECO economic operation mode and can achieve more than 97% efficiency, this ECO economic operation mode adopts "bypass direct power supply" mode because it actually abandons the normal function of UPS, sacrifices the basic functions of UPS such as voltage stabilization and resistance, and buries hidden dangers for users'use, which undoubtedly violates the original purpose of using Corstal UPS power supply. Therefore, it is seldom used.
In addition, load and overload capacity are also key indicators reflecting the quality of Kosta UPS power supply. There are two situations when the load really needs UPS to play a protective role: when the grid voltage is abnormal or when the load is abnormal.  When the grid voltage is abnormal (including power failure), the protection of load relies on UPS input circuit and uninterrupted function, while when the load is abnormal, the protection of load relies on the load and overload capacity of UPS.  Generally, the low load capacity of the traditional Dual-Conversion Corstal UPS power supply is due to the simplicity of its load power factor, which makes it difficult to adapt to different types of loads.
Corstal UPS Power Supply Component
Corstal UPS power supply system is generally composed of UPS mainframe, bypass voltage regulator, output feeder cabinet and other three parts (small power can also be three in one).
1. UPS main cabinet: input-output isolation transformer, rectifier, inverter, static bypass switch, bypass switch, backstop diode;
2. Bypass isolation voltage regulator: bypass isolation transformer, bypass voltage regulator, manual/bypass maintenance switch;
3. Feeder cabinet: circuit distribution unit, monitoring instrument, control switch and signal indication, etc.
The special UPS power supply adopts 1+1 redundant power supply system. Aiming at the application load and environment of power system, the industrial AC protection power supply manufactured by advanced technology can fully meet the demand of power supply reliability for load such as power DCS system.
UPS mainly consists of the following systems, using two-stage transformation. The first stage converter uses a rectifier (AC-DC).
The alternating current after the input isolation transformer is transformed into a stable direct current. The second stage converter (DC-AC) uses an inverter power supply to convert the rectified DC output into sinusoidal AC output through isolation to the load.
Isolation part: Input isolation transformer isolates AC input from DC to protect DC side equipment; Output isolation transformer isolates AC and DC input from AC output to protect load side equipment. Dual isolation ensures true and complete electrical isolation of three ports: DC input, AC input and AC output.

整流部分：将输入的交流市电转变为稳定的直流，送入逆变设备。

逆变部分：将外部直流或经过整流后的直流电源转变为稳定的正弦波交流电源。

控制部分：控制逆变器电源跟随基准市电，并与其保持相同的相位和频率，自动调节，并使电源在规定的范围内，按照设定的保护定值运行或保护。

显示部分：采用LCD及LED状态模拟盘，准确反映设备运行状态及故障信息。

切换部分：采用继电器或静态电子开关，对旁路、市电和逆变器输出电源进行自动切换。
