Abstract

According to the structural characteristics of the disconnecting switches in GIS equipments,an online contact temperature monitoring method based on IR(Infra-Red) sensing is proposed. Highly emissive coating is spread on the contact surface to enhance its emissivity and the emissivity of infrared temperature sensor is adjusted to compensate the absorption effect of SF6. A GIS experiment platform is established and the influences of SF6concentration,IR filter and environmental temperature on IR sensing are researched. Experimental results show that,the indication of IR sensor reduces along with the increase of SF6 concentration,which could be compensated by lowering the emissivity of sensor. An online GIS contacts temperature monitoring system is designed based on the proposed method.

基于红外传感的GIS开关触点温度在线监测

针对GIS设备中断开开关的结构特点，提出了一种基于红外传感的接触式温度在线监测方法。在接触面涂覆高发射涂层以提高其发射率，并调节红外温度传感器的发射率以补偿SF6的吸收效应。建立了GIS实验平台，研究了sf6浓度、红外滤光片和环境温度对红外传感的影响。实验结果表明，随着SF6浓度的增加，红外传感器的指示值降低，可以通过降低传感器的发射率来补偿。基于该方法，设计了一个在线GIS接触式温度监测系统。
