科士达UPS电源蓄电池的放电测容量

在科士达UPS电源蓄电池测试中，放电法是普遍采用一种方法。测试间隔一般是一年一次，以检验电池组的容量。放电测试的一般步骤和注意事项主要包括：

1.科士达UPS电源蓄电池配置假负载，设定合适的放电率

实际操作的困难：假负载比较笨重，并非每个场地都有。对于大容量的电池组，假负载的功率要求更高

变通的做法：使用真实负载放电(某些企业也会在蓄电池使用的前3-5年使用真负载进行核对性放电，放出标称容量的30%-40%)

风险：真实负载不可控，无法实现恒流放电;功率也比较小，不能达到足够的放电倍率

2.科士达UPS电源蓄电池断开充电器

实际操作的困难：负载实际处于无保护或保护不充分状态

变通的做法：缩短放电时间，或在专门的维护窗口进行

风险：如果电池容量严重劣化，很可能在断开充电器的瞬间发生断电事故;如果在有限的维护窗口内缩短放电时间，就不能完成完整的放电测试，也就不能算得每节电池的实际容量

3.监控科士达UPS电源蓄电池放电电流是否恒定

实际操作的困难：要缩短放电时间就要加大电流，通常高达几百安培

风险：需要选用专门的电缆，否则很可能起火燃烧;必须保证假负载的散热，否则可能发生事故

4.定期监控每节科士达UPS电源蓄电池的电压，一旦某节电池电压下降到截止电压，就暂停放电。计算该节电池的容量

实际操作的困难：不知道何时会达到截止电压

Discharge method is widely used in the battery test of Kosta UPS power supply. The test interval is usually once a year to check the capacity of the battery pack. The general steps and precautions of discharge test include:
1. Corstal UPS battery is equipped with false load to set appropriate discharge rate.
Difficulties in actual operation: False load is heavy, not every site has. For large capacity batteries, the power requirement of false load is higher.
Alternative: Use real load discharge (some enterprises will also use real load for checking discharge in the first 3-5 years of battery use, releasing 30-40% of nominal capacity).
Risk: The real load is uncontrollable and constant current discharge can not be achieved; the power is relatively small and can not achieve enough discharge rate.
2. Corstal UPS Power Battery Disconnect Charger
Difficulties in actual operation: the load is actually unprotected or under-protected
Alternatives: Shorten discharge time, or at a dedicated maintenance window
Risk: If the battery capacity is seriously deteriorated, it is likely that a power failure will occur at the moment of disconnection of the charger; if the discharge time is shortened within a limited maintenance window, the complete discharge test will not be completed, and the actual capacity of each battery will not be calculated.
3. Monitor whether the discharge current of the UPS battery is constant
Difficulties in practical operation: To shorten the discharge time, it is necessary to increase the current, usually up to several hundred amperes.
Risk: Special cables need to be selected, otherwise fire is likely to burn; heat dissipation of false loads must be guaranteed, otherwise accidents may occur.
4. Regular monitoring of the voltage of each Kosta UPS battery, once a battery voltage drops to the cut-off voltage, the discharge will be suspended. Calculate the capacity of the battery
Difficulties in actual operation: Do not know when the cut-off voltage will be reached

变通的做法：频繁的测试电压;缩短放电时间，避免放到截止电压;在放电结束时横向比较各节电池的电压，电压较低的为落后电池

风险：一旦某节科士达UPS电源蓄电池快速达到截止电压而没有被发现，很可能造成过放，甚至燃烧;如果不放到截止电压则无法准确计算容量;横向比较电压仅能做定性判断

5.将该节科士达UPS电源蓄电池电池从电池组中取走，继续放电和步骤4直到所有电池都到达截至电压，算出每节电池的容量

风险：当某节电池到达截止电压时就停止放电，最多精确计算最差那节电池的容量

6.在下一个维护周期进行科士达UPS电源蓄电池放电测试

实际操作的困难：最频繁的测试周期也为一年一次

风险：在长达一年的测试间歇期内电池的健康状态不可知;过于频繁的放电测试会消耗电池的循环寿命(一般为200-500次)

一 机房科士达UPS电源蓄电池常见故障

1 机房科士达UPS电源蓄电池着火和爆炸

目前，数据机房蓄电池爆炸着火事故频发，导致业主损失严重。一般机房电池是由于其中一节电池裂化后未妥善管理，电池急剧恶化导致爆炸着火。由于电池是串联及并联在使用，只要一节着火燃烧，整片瞬间会蔓延开来，导致大的火灾事故。

2 科士达UPS电源蓄电池主要故障及失效的主要原因

Once a section of Corstal UPS battery quickly reaches the cut-off voltage and is not found, it is likely to cause over-discharge or even combustion; if it is not placed in the cut-off voltage, it is impossible to accurately calculate the capacity; lateral comparative voltage can only be qualitative judgement.
5. Remove the battery from the battery pack, continue discharging and step 4 until all the batteries reach the cut-off voltage, and calculate the capacity of each battery.
Risk: When a battery reaches the cut-off voltage, it stops discharging and calculates the capacity of the worst battery accurately at most.
6. Conduct battery discharge test for Corstal UPS power supply in the next maintenance cycle
Operational difficulties: The most frequent test cycles are also once a year
Risk: The battery's health is unknown during the test interval of up to a year; excessive discharge testing consumes the battery's cycle life (usually 200-500 cycles).
Common Faults of UPS Battery in a Computer Room
Fire and Explosion of UPS Power Battery in 1 Computer Room
At present, the explosion and ignition accidents of storage batteries in data room are frequent, resulting in serious losses for owners. In general, the battery in engine room is due to the improper management of one of the batteries after cracking, and the rapid deterioration of the batteries results in explosion and fire. Because the batteries are in series and in parallel, as long as one section is on fire, the whole piece will spread in an instant, leading to large fire accidents.

The Important Role of On-line Monitoring of UPS Power Battery in Computer Room
With the development of technology, a new detection method has emerged. Battery on-line monitoring technology has been applied to battery monitoring in data center. It has been proved to be a very necessary and effective method through a lot of time.
The main functions of on-line monitoring of UPS battery are as follows:
1. Preventing accidents and monitoring accumulators online can provide early warning and controllable management.
2 On-line 24-hour monitoring, accurate measurement data, keep abreast of battery status, greatly reducing the amount of manual maintenance.
3. It can realize network, automation management and remote monitoring.
4. The operation data of different brands of batteries can be accumulated, and the product selection in the future can be realized through large data analysis.
5. Save a lot of manpower and material resources.
The main analysis functions of Keshida UPS battery monitoring system are as follows:
1 Automatic analysis of battery residual capacity
2 Analyse whether the battery is invalid or needs activation
3. Analyse the monomer voltage of float charging and find out the batteries that need to be charged.
4. Analyse the monomer voltage when floating charging, find out the overcharged battery
5. Analyse the floating charging group voltage to determine whether the charger voltage is too high or too low.
We know that the function of batteries is to ensure the uninterrupted power supply to the data center through the DC/AC inverters of UPS during the start-up and switching time of standby generators after power failure. With the development and perfection of data center technology, the battery standby time in modern data center is theoretically the maximum available time. Designers can not reduce this time to tens of seconds, but 5-10 minutes is enough. Corstal UPS battery plays a key role in solving the sudden power situation in data center. So, what problems still exist in the current application of battery products?
1. Influenced by traditional concepts, the planning backup time is generally too long.
2. Installation layout is not standardized, maintenance space is small, and quick repair function is lost.
3. The monitoring and management system is not perfect.
4. Manufacturing links: Due to the change of manufacturing cost, the lead plate thickness of new batteries is generally reduced, and the ratio of electrolyte acid is increased, which directly affects the long service life of batteries.
5. With the emergence of a large number of high-life batteries, the maintenance workload and operation risk of Kosta UPS batteries increase. But the maintenance method has not changed.
6. Battery system faults show an obvious upward trend. The discharging capacity of UPS batteries in Costa is insufficient, and malignant accidents of battery combustion and explosion occur from time to time.
7. The quality of products should not be neglected. Tests show that if the power is cut off once a day, the battery of the general manufacturer will leak and bulge to varying degrees, and the service life will be less than half a year.
Corstal UPS battery is one of the necessary factors to determine the security and stability of a data center. For the application of Corstal UPS battery products, product quality should be strictly controlled and battery products that are most suitable for its own data center should be selected to ensure the normal operation capacity of the data center and reduce unnecessary losses.

模块化科士达UPS电源蓄电池不仅拥有高可靠、易维护、易扩容等特点，而且还具有提高数据中心适应性的作用。模块化科士达UPS电源蓄电池节省了数据中心的运营成本，提高了数据中心长期运行的稳定性。因此，我们要了解模块化UPS产品，使其在数据中心中发挥更大的作用。

一、首先检查科士达UPS电源的绝缘

在科士达UPS电源中，组件部分的直流地是悬空的，且和框架是隔离的，所以，必须考虑组件和框架之间的绝缘，通常在组件和框架之间潜在着几十伏的电位差。

二、其次还要读出科士达UPS电源显示器的故障报警信息

三、零伏电压参考点

1、PCB ALIP FAULT(电源板故障)

检查和分析：

1)检查ALIP的输入电压是否正常;

2)检查ALIP板输出有无短路，在PC板起动瞬间的冲击电流有可能使ALIP板的输出短路，并引起ALIP板保护电路动作，或使ALIP板损坏。

2、EMERGENCY POW OFF紧急停机

可能原因：

1)在FLIP板上，检查XR9的1-2接点间的跨接线是否接好;

2)在FLIP板和AQCP析跟踪观察这个“emergency power off”(紧急断电)信号是否异常;

3、PCB AQCP/AQOP/CANP/CHAP ODUP/AFIP/DISPFAULT

第一种原因：更换显示的PC板，如果故障仍未消除，检查联接后更换CANP板。

第二种原因：如果自诊断显示几个板都有故障，更换CANP板。

4、COFP FAULT

可能原因：

1)起动UPS时，当一合上开关Q1，UPS就驱动所有PC板，并分析每块板送来的各种响应，为了获得来自遥控器的有关响应，遥控器供电必须先比UPS投上，即，当起动UPS时，必须先合上Q4S开关，然后合上Q1开关，如果UPS和遥控器都已投上，则用一个诊断功能程序做一次复位;

2)检查遥控器的输入电源(220V)是否正常，FILP板上FU23、FU22(2A)保险丝是否熔断;

3)遥控器上AFIP板的R35电阻是否已去掉，正常是没有的;

4)如果没有接遥控器，但还是出现上述现象，则：

a)检查UPS内部程序预置是否正常;

b)检查PC板之间的联接;

c)更换CANP板。

5、科士达UPS电源蓄电池故障

1)第一种原因：非常强的氢气味和见到铜或黄铜部件被氧化;电池膨胀厉害并一个接一个的挤在一起。为了判断其原因，我们必须确定这些是否是在一个相对短的时间(8～10小时)内发生的，如果是，则可能原因为调节故障，可能由PC板CHAP或AQCP造成，可做一个充电器起动测试(QF1断开)，并检查实际直流电压;

2)第二种原因：电池膨胀，如果逆变器已关断了一个较长的时间，温度可能已下降，则检查其数量和对应的浮充电压;找出短路的电池。

4)更换CHAP板，然后充电器模块(一个故障的CHAP板可能会损坏新的充电器)。

13、INV RUSE BLOWN(输出保险丝断)

这些保险丝通常在负载切换至逆变器的时候熔断，原因是在输出变压器内有一个过大环流。

为了找出科士达UPS电源原因，可做以下检查：

1)断开Q4S开关，用强迫法起动逆变器，并强迫切换至负载;

2)检查静态开关可控硅是否良好，K3N线圈是否正常;

如果面板上发光二板管在切换时熄灭，则可能静态开关的可控硅故障，或逆变器相序和相位故障;

3)检查电源2输入阻容保护电路;

4)检查电源中性线是否符合标准;

5)检查逆变器柜和电池柜(架)的接地是否良好;

6)检查负载有无短路。

14、LEGX DESA TURA TION

1)检查风机接线、插头有无松动，检查有无异常噪音;

检查FILP板上保险丝FU13、14、15、16(2A)是否正常;

2)检查AQOP板XM603的10/11针之间的电压是否为0V，该值可在AQOP板上电阻R37处测量，若UR37=0V，则正常;

3)若上述测量值正确，但还是显示“INV FAN FAIL URE”，则更换AQOP板;

4)若更换AQOP板后还是一样，则FILP板上TQ1故障。

24、OVER TEMPET TURE AND SWITCHING MICROCONTACT FAULTS(过热及开关的微动开关故障)
