银川台地电仪断线器装置改造实验

针对银川地电台查漏电工作中现有断线器装置存在的问题和不足,所做的改造实验。实验根据银川地电台观测点实际线路布设,利用继电器的开、合原理为设计思路。通过实际试验用继电器和线路,在地埋电缆的供电极和测量极线路中进行测试,实现了线路与电极断开和接通,可替代现有故障断线器的工作,也可作为测量极线路断线装置。实验结果满足地电线路查漏电和测绝缘工作时线路断开的需求。

IMPROVEMENT EXPERIMENT OF DISCONNECTION DEVICE OF GEOELECTRIC INSTRUMENT AT YINCHUAN SEISMIC STATION

This article summarizes that modification experiments have been done to check the leakage work aiming at the existing problems and insufficiency of geoelectric disconnection device. This topic experiment based on the actual line layout at observation point of Yinchuan geoelectric station used of open and principle of the relay for design. With relay and through practical test circuit, the buried cable in the lines of power supply and measuring pole test, implements the disconnection and connection lines with electrodes, and the alternative of existing fault break line, also can be used as measuring circuit disconnection device. The experimental results meet the electric circuit to check the leakage and line disconnect the demand of measuring insulation work.
