摘要:监测分站备用电池作为矿井监控设备的备用电源,其性能优劣直接关系到分站在交
流供电不正常的情況下,监测分站能否正常运行,连续监测,即系统工作的可靠性问题。为保证
分站备用电池的性能,延长其使用寿命,一般生产厂家要求用户每月对分站电池进行完全放电一
次,而现有放电方式均是米用传统人エ井下现场操作,费工费时,对矿井正常生产影响很大,且
难以操作,放电效果差。针对以上问题,研制出了矿井监测分站备用电池地面远程遥控全自动放
电装置,只需通过地面监控中心计算机向井下分站发出远程放电遥控指令,井下监测分站备用电
池便会自动放电,放电结束又会自动恢复为交流供电。

Abstract The poor or excellent performances of the standby battery in the monitoring and measuring substation would have
direction relationship to the normal operation of the substation. In order to ensure the performances, the battery
manufacturers would ask the end users to have a safety discharging of the battery in the substation per month. The present
discharging is operated by manual in underground mine. The discharging would be a cost and timing operation. The
operation would be difficult and the discharging results would be poor. According to the above problems, a surface remote
controlled full automatic discharging device was researched and developed for the standby battery in the mine monitoring and
measuring substation. With the remote controlled discharging instruction from the surface to underground mine substation by
the computer in the surface monitoring and measuring center, the standby battery in the substation would be automatically in
power discharging and would be automatically reset for the AC power supply when the discharging operation terminated
