摘要
为了解决电力通信电源异常中断影响通信网络正常运行的问题,通过对现有应急电源的不足之处进行分析,并对各种材料锂电池性能综合比较、分析评估,设计研发了一种以三元锂电池为储能单元,具有安全控制保护、状态监测显示功能,体积小、重量轻、可循环应用及方便携带等特点的48 V/50 A·h电力通信应急电源装置。试验结果表明,这种三元锂电池储能单元可满足变电所通信站4 h以上应急供电需求,实际应用效果显著,推广前景广阔。
In order to solve the problems that exception interrupt of communication power affects the normal operation of communication network, through analysis and evaluation of the shortcomings of the existing emergency power supply mode, as well as comprehensive comparison of a variety of material properties of lithium battery. A 48 V/50 A·h power communication emergency power supply device is design and developed, which uses ternary lithium battery as energy storage unit, with functions of safety control and protection, status monitoring display, features of small size, light weight, recycled use and easy portability, which can meet emergency power supply needs of more than 4 hour in the communication station of transformer substation. The effect of the practical application is significant, and with better prospect.
