摘要
中性点经电阻接地的运行方式在城市配电网中广泛应用,为监测接地电阻的运行工况,市区供电公司在35 kV及以上变电站装设中性点接地监测装置,但该装置的功能较为单一,并未发挥相应作用.本文对这个装置在逻辑和功能模块上进行改进,不仅增加人机互动性,而且提高工作效率.
Abstract
The operation mode of the grounding at the neutral point through small resistance is applied widely in urban distribution network.To monitor the working condition of grounding resistance,the monitoring apparatus is applied in substations whose voltage level is above 35kV in urban power supply company.Meanwhile,the function of the apparatus is single,unable to play a corresponding role.In this issue,the improvements on logical and function mode of the monitoring apparatus are illustrated,to increase the human-computer interaction and improve working efficiency.
