开关柜母线温度的在线监测
摘要
本文介绍开关柜在线监测系统中对母线及其接触部位温度的测量方法。采用接触式测量
将高电位上的温度信号调制成红外光脉冲信号向外发射
地电位柜体上的接收方将光脉冲信号还原为温度信号。此法具有很好的快速跟随性及准确性
Abstract
A method to measure the temperature of the bus bar for switchgear cubicle on-line monitoring system is presented in this paper.With a sensor being contacted with the measured point
the signal of temperature at high potential is modulated into optical pulse.The receiver at earth potential in cubicle receives the optical pulse and restores the signal of temperature.It’s a good and accurate method with short response time and high accuracy.
