结构特点
阀控密封铅酸蓄电池(以下简称电池)是由正极板、负极板、AGM隔膜、稀硫酸电解液、安全阀、电池壳和电池盖等组成。电池可组装成2V、6V、12V,电池每2V为一单体。有以下几个特点:
1、电解液吸附在隔膜和极板中,电池中无游离电解液,电池无渗漏,在使用过程中,不需定期加水调整电解液的维护,使用方便。
2、普通的开口式铅酸蓄电池在充电过程中,正极板析出氧气,负极板析出氢气,电池中释放出大量气体。阀控密封铅酸蓄电池,采用特殊的电池结构和免维护极板,使电池在浮充电过程中,正极板产生的氧气通过隔膜在负极板表面复合,并抑制负极板氢气的析出,电池不会释放氧气。正极板腐蚀产生的极少量氢气通过电池上安全阀排出。因此,电池在使用过程中无酸雾析出,不污染环境、不腐蚀设备。
3、由于氢气的析出,加速了电池中水份的损失,电池容易失水干涸。

UPS即不间断电源,是将蓄电池(多为铅酸免维护蓄电池)与主机相连接,通过主机逆变器等模块电路将直流电转换成市电的系统设备。主要用于给单台计算机、计算机网络系统或其它电力电子设备提供稳定、不间断的电力供应。当市电输入正常时,UPS将市电稳压后供应给负载使用,此时的UPS就是一台交流市电稳压器,同时它还向机内电池充电;
当市电中断(事故停电)时,UPS立即将电池的直流电能,通过逆变零切换转换的方法向负载继续供应220V交流电,使负载维持正常工作并保护负载软、硬件不受损坏。UPS设备通常对电压过大和电压太低都提供保护。
UPS电源在使用和维护的过程中应该注意以下几点:
(1)UPS电源主机对环境温度要求不高,+5℃~40℃都能正常工作,但要求室内清洁,少尘,否则灰尘加上潮湿会引起主机工作紊乱。储能蓄电池则对温度要求较高,标准使用温度为25℃,平时不能超过+15℃~+30℃。温度太低,会使储电池容量下降,温度每下降1℃,其容量下降1%。其放电容量会随温度升高而增加,但寿命降低。如果在高温下长期使用,温度每高10℃,电池寿命约降低一半。
(2)主机中设置的参数在使用中不能随意改变。特别是对电池组的参数,会直接影响其使用寿命,但随着环境温度的改变,对浮充电压要做相应调整。通常以25℃为标准,环境温度每升高或降低1℃时,浮充电压应增加18mV(相对于12V蓄电池)。
(3)在无外电靠UPS电源系统自行供电时,应避免带负载启动UPS电源,应先关断各负载,等UPS电源系统起动后再开启负载。因负载瞬间供电时会有冲击电池,多负载的冲击电流和加上所需的供电电流会造成UPS电源瞬间过载,严重时将损坏变换器。
(4)UPS电源系统按使用要求功率余量不大,在使用中要避免随意增加大功率的额外设备,也不允许在满负载状态下长期运行。
(5)自备发电机的输出电压,波形、频率、幅度应满足UPS电源对输入电压的要求,另外发电机的功率要远大于UPS电源的额定功率,否则任一条件不满足,将会造成UPS电源工作异常或损坏。
(6)由于组合电池组电压很高,存在电击危险,因此装卸导电联接条、输出线时应用安全保障,工具应采用绝缘措施,特别是输出接点应有防触摸措施。
(7)不论是在浮充工作状态还是在充电、放电检修测试状态,都要保证电压、电流符合规定要求。过高的电压或电流可能会造成电池的热失控或失水、电压、电流过小会造成电池亏电,这都会影响电池的使用寿命,前者的影响更大。
Due to the wide use of lead-acid batteries, coupled with the actual service life is short, every year China's lead-acid battery life is about two hundred million. "At least 50 million of the two hundred million out of the lead acid batteries that are eliminated each year can be repaired and regenerated." Guangzhou Wang Huai energy science and technology limited company (hereinafter referred to as Guangzhou Wang Huai) technology personnel, repair technical limitations, these batteries are eliminated most have not been used, resulting in waste materials, has also brought environmental pollution. However, the day before the company after more than ten years of research and development of successful lead-acid battery repair technology, has been recognized by industry experts, the use of lead-acid batteries to find a way out.
Present situation
In the short life of lead-acid battery, a serious waste of resources
1859, the official launch of lead-acid batteries. During the one hundred years after its invention, the lead-acid battery is widely used because of its safety, reliability, simple production process, low cost and so on. According to statistics, 95% of the world's backup energy systems are using lead-acid batteries.
After more than 100 years of development, the lead-acid battery has made great progress in theoretical research and product performance, however, the disadvantages of the short life cycle of lead-acid battery have not been effectively solved. The design life of the storage battery is usually 8 years to 12 years, but in the actual use, the life of the storage battery is usually only 3 years to 5 years.
"The core reason for the short life of lead acid battery is that the redox reaction of the battery is the inevitable product of Pb2SO4 (lead sulfate), which will lead to the formation of irreversible lead sulfate crystals." Guangzhou Wang Huai chairman Huang Shangnan introduction, the main components of the lead-acid battery is metallic lead and sulfuric acid solution, it will gradually produce irreversible Pb2SO4 crystallization in the working process, it is often said that the sulfation. Pb2SO4 crystal belongs to chemical substances is very stable, and poor conductivity, large volume, will plug the porous plates. Osmosis prevent electrolyte, increase the battery's internal resistance, not easy to be reduced two lead oxide and lead metal in reversible charging, to participate in the electrochemical reaction of active substances in the plate reduced, reducing the capacity of that led to the final failure of battery scrap.
(8)在任何情况下,都应防止电池短路或深度放电,因为电池的循环寿命和放电深度有关。放电深度越深、循环寿命越短。在容量试验中或是放电检修中,通常放电达到容量的30%~50%就可以了。
(9)对电池应避免大电流充放电,虽说在充电时可以接受大电流,但在实际操作中应尽量避免,否则会造成电池极板膨胀变形,使得极板活性物质脱落,电池内阻增大,温升越高,严重时将造成容量下降,寿命提前终止。
掌握了以上使用UPS电源的注意事项后,维护人员还要认真做好日常的维护与检修,这里结合自己的日常维护体验给大家以下几点提示与工作建议:
(1)UPS电源在正常使用情况下,主机的维护工作很少,主要是防尘和定期除尘。特别是气候干燥的地区,空气中的灰粒较多,机内的风机会将灰尘带入机内沉积、当遇空气潮湿时会引起主机控制紊乱造成主机工作失常,并发生不准确告警,大量灰尘也会造成器件散热不好。一般每季度应彻底清洁一次。其次就是在除尘时,检查各连接件和插接件有无松动和接触不牢的情况。
(2)虽说储能电池组目前都采用了免维护电池,但这只是免除了以往的测比、配比、定时添加蒸馏水的工作。但外因工作状态对电池的影响并没有改变,不正常工作状态对电池造成的影响没有变,这部分的维护检修工作仍是非常重要的,UPS电源系统的大量维修检修工作主要在电池部分。储能电池日常维护中需经常检查的项目有:清洁并检测电池两端电压、温度;连接处有无松动,腐蚀现象、检测连接条压降;电池外观是否完好,有无壳变形和渗漏;极柱、安全阀周围是否有酸雾逸出;主机设备是否正常。
(3)当UPS电池系统出现故障时,应先查明原因,分清是负载还是UPS电源系统;是主机还是电池组。虽说UPS主机有故障自检功能,但它对面而不对点,对更换配件很方便,但要维修故障点,仍需做大量的分析、检测工作。当自检部分发生故障,显示的故障内容则可能有误。
(4)对主机出现击穿,断保险或烧毁器件的故障,一定要查明原因并排除故障后才能重新启动,否则会接连发生相同的故障。
(5)当电池组中发现电压反极、压降大、压差大和酸雾泄漏现象的电池时,应及时采用相应的方法恢复和修复,对不能恢复和修复的要更换,但不能把不同容量、不同性能、不同厂家的电池联在一起,否则可能会对整组电池带来不利影响。对寿命已过期的电池组要及时更换,以免影响到主机。Waste lead-acid batteries a large number of harding, on the one hand led to the waste of resources. On the other hand, lead-acid batteries contain lead, sulfuric acid and other waste, has the characteristics of strong pollution and non degradable, at present a lot of places on the recycling of waste lead-acid battery is still not standardized by the state, the enormous risks of water and soil.
change
In the successful development of the lead-acid battery activator, lead-acid battery recycling regeneration
and current of the battery, you can achieve the regeneration of lead-acid battery. The battery activator in the acidic environment, combined with the externally applied voltage activated battery, can catalyze the decomposition of lead rystal battery before restoration presented on large, after repair into floc, the effect is very intuitive. Using the monitoring instrument on the market can also be seen, after the repair of the battery capacity, resistance have been r
