摘要
高压开关柜是变电站的重要电气设备,它担负着闭合及断开电力线路、保护系统安全的双重作用。高压开关柜长期工作在高电压、大电流、强磁场的环境下,触头的氧化、接触电阻的增大常常使触头发热,温度过高,如不及时发现并处理可能会引发火灾、停电、爆炸等严重事故。因此,高压开关柜内实时温度监测问题已经成为电力系统中亟待解决的实际问题。文章提出一种基于单片机的高压开关柜无线测温系统,该系统具有结构简单,测温准确度高等特点。
High voltage switch cabinet is important electrical equipment in substation. It takes on double functions of closing and disconnecting power line and protecting system safety. High voltage switch cabinet in high voltage, large current and strong magnetic field environment for a long time, high contact oxidation, increased contact resistance often make contact heating, temperature, if not promptly found and dealt with, it may lead to fire, power failure, explosion accidents and other serious accidents. Therefore, the real-time temperature monitoring in high voltage switchgear has become an urgent problem in power system. In this paper, a wireless temperature monitoring system of high voltage switch cabinet based on single chip microcomputer is proposed, which has the characteristics of simple structure and high temperature measurement accuracy.
