| 摘 要： | 为解决现有的GIS绝缘检测装置存在的体积大、不易实现在线检测、受周围环境影响,测量精度不高等问题,笔者采用时差计算法,对局部放电源进行定位,并通过由高通滤波器、宽带放大器、检波器、电/光变换器和光/电变换器组成的两个通道,分别接收和处理两个来自不同位置检测到的局放信号,从而使检测精度大大提高。实验结果表明,该系统具有重量轻、携带方便、灵敏度高,可实现局放源定位等特点。

| Abstract: | Nowadays,the disadvantages of GIS(gas-insulated-switchgear)included: voluminous,difficultly detecting on line,easily influenced,low precision.So the instrument adopts the methold of calculate the difference of the receiving time to locate the resource of the partial discharge(PD).The PD signal is received and processed by two same circuits which are installed in different positions and made up of high frequency filter,amplifiers,detectors,the electric/light transformers,the cables and the light/electric transformers and so on.Therefore,the detecting precision is greatly increased.It is shown that this instrument is light,easy carrying,high sensitive,and precise orientition of the PD source. |
