摘要
在发电厂和变电所内，直流系统接地故障的检测，过去一直采用手动方式来完成。这样，既费事又危险。我们研制的直流系统接地自动检测装置不需停电，可自动检测直流系统接地故障。本文介绍了该装置的原理、组成和主要电路。
In electric power plants and substations, a detection of DC system ground fault was usually completed in hand manner, which is very much trouble and danger. A new instrument developed by us can automaticlly detect DC system ground fault and needs no to cut AC power. The advantages of the new instrument are convenient and safe. The principle, composition and major circuits of the detector are described in this paper.
