高压開关柜温度在线监测系统

摘要

開关柜是保证電力系统安全运行的重要设备之一，不過常常由于開关柜局部過热，而引起事故，导致损失。在以往的開关柜過热故障检测中，采用人工巡检，不仅费時、费力，并且不易及時发現事故。開关柜過热故障在线监测系统不仅克服了開关柜内高温、高压、强磁場环境下温度不易监测的难題，并且通過监控软件实時显示開关柜内测點的目前温度值，并做出报警处理，节省了大量人力、物力，提高了事故预判的精确性、实時性。

本文從硬件和软件两個方面简介了监测系统的设计過程。硬件方面设计了两种不一样的温度传感系统：中压開关柜過热故障监测采用光纤式温度传感器，同步采用光纤传播数据；低压開关柜采用單总线数字式温度传感器，数据采用無线传播。监测系统软件重要实現了实時显示测點温度，并對温度数据做出分析、报警、保留等功能。及時提醒工作人员對报警状况做出处理，防止事故的发生。
