资料介绍

针对开关柜内部接触不良或线路老化等因素引起的局部放电现象导致设备不安全运行的现状,本文设计出一种基于光敏传感器和差分电路的开关柜放电检测方法.该方法具有成本低、灵敏度高、抗干扰能力强等优点,通过实验室电火花发生器和变电站内开关柜放电现象检测,并与NRJFD-3000数字局部放电检测仪检测结果对比,显示该系统能实现对开关柜内部放电现象的实时准确监测.

A method based on photosensor and differential circuit was presented to detect for a discharge of switch cabinetdue to the partial discharge phenomenon caused by bad contact inside the switch cabinet or circuit aging resulting it in unsafeoperation. It had some advantages of a low cost, high sensitivity and strong anti-jamming capability. It was detected ondischarging state of electrospark generator in a laboratory and a switch cabinet in a transformer station and test results werecompared with local discharging digital device NRJFD-3000. Result showed that the system could realize real-time accuratemonitoring of internal discharge switch cabinet.
