缩短35kV及110kV变电站蓄电池放电试验时间

Shorten the discharge time of battery in 35kV and 110kV substation

在电网出现较大事故时,失去交流的站用电后,蓄电池成为变电站唯一的直流电源。并且对站内事故照明、分合闸回路、储能回路和二次装置提供了所需要的的直流电源,所以蓄电池是否可靠,成为站内安全运行的关键。为此,如何安全地做好蓄电池试验、维护工作意义重大。文中首先简单阐述核对性放电试验的工作流程,然后分析各工作环节影响因素,并针对关键因素采取相应改进方法,最后总结改进方法后的效益作用。

A larger accident in power grid,loss of communication station power battery,as the only power supply provides reliable DC power station for protection device,control circuit and signal circuit and emergency lighting,whether it reliable,safe operation of the substation plays an important role.Therefore,it is of great significance to do a good job in battery testing and maintenance.In this paper,the working process of the verification discharge test is simply described,and then the influencing factors are analyzed,and the corresponding improvement methods are put forward according to the key factors.
