摘要
因开关柜母线连接处过热而产生的事故时有发生故有必要对母线连接处进行温度监测。但由于母线运行处于高电压状态,直接测量其温度是电力系统在线监测的难题。介绍了一款基于无线通信的母线测温系统,该系统采用锂电池供电,通过频段为433M的电磁波进行数据传输。
The accident happens from time to time due to high temperature of contacts of bus-bar in switchgear cabinet, so it's necessary to check the temperature of connector of bus-bar. But it is difficult issue to monitor the temperature directly under high voltage. A system of the temperature measurement of bus-bar connector based on wireless communication is introduced in this paper, the system adopts Li battery for its power supply and the data is transmited by electromagnetic wave which frequency is 433M Hz.
