变电站母线接地开关配置的探讨

Approach on the Disposition of Grounding Switches in Substation

对于屋外配电装置,为保证电气设备和母线的检修安全,应恰当地配置母线接地开关。停电母线上电磁感应电压,取决于平行带电母线的电流和它们的相对间距。通过实例分析,介绍了确定母线接地开关的安装数量和间距的计算方法。

To ensure the safety of maintenance work and out-door power installation, bus bar grounding switches should be properly equipped. The electromagnetic induced voltage on the outage bus bar（s） depends upon the current in nearby parallel live bus bar and their relative distances. Through a calculation example, the method for determinating the location and number of the grounding switches is introduced.
