具体实施方式
如图1所示，本实用新型在电容补偿柜中设置电力电容保护器，上述的电力电容保护器中设置有至少一个信号采集装置，信号采集装置将采集到的报警信号经过光电隔离器输送至单片机，单片机的输出端通过通讯模块连接报警终端设备；且单片机和通讯模块均与电源模块相连接。
其中，每台电容补偿柜中均安装GT300电力电容器保护器，能够对可能出现的断相、过流、过压、三相不平衡等故障均采用反时限特性进行保护；当发生故障时电容器保护器切断回路控制电源并输出报警信号，报警信号通过光电隔离，与单片机信号检测输入端相连。能准确无误告知电气值班维修人员哪只电容器回路故障，有利于快速修复与调整，提高了设备利用率。
信号采集装置为设置在电力电容器内部的报警触点97、98构成。
单片机是承前启后实现电容补偿柜远程监控人机对话的指挥中心，它将采集到保护装置动作情况等信息进行处理、分析、判断，控制GSM电路向电气值班维修人员报警；根据GSM电路接收到的设备制造厂家售后服务监控平台发出的指令进行处理，去调整智能无功补偿控制器的参数，实现远程人机对话。
上述的电源模块包括充电回路和镍氢电池组，充电回路与稳压电路相连接。电源模块是AC/DC变换为电容补偿柜远程监控装置供电，了防止停电GSM单元无法工作，设计安装有可充电的镍氢电池组作为后备电源后备电源。有了后备电源，既使失去AC电源，电容补偿柜远程监控装置也会正常工作。
