摘要
直流电源正负两极对地是绝缘的,在安装、调试、运行过程中难免会出现线接错位置、电缆绝缘受损老化。当发生一点接地时虽然系统允许运行,但是需要维修人员尽早找到接地点并处理,以免发生两点接地造成事故。
The positive and negative poles of the DC power supply are insulated to the ground. In the process of installation, commissioning and operation, it is inevitable that there will be wrong position of wire connection and damaged and aging of cable insulation. When one point grounding occurs, although the system is allowed to run,maintenance personnel need to find the connecting point as soon as possible and deal with it, so as to avoid the occurrence of two points grounding accidents.
