10 kV小电阻接地系统的接触电压安全性研究

Research on the Contact Voltage Safety of 10kV Small Resistance Grounding System

我国城市建设的脚步越来越快,经济也不断发展。详细分析讨论了我国各大城市的中低压配网的接地拓扑结构问题,对10 k V配网中性点经小电阻接地后的10 k V侧接触电压存在的一些安全隐患以及条件等进行研究,同时根据单台区独立式和多台区互联式两种类型的台区接地方式,设计、建立场路模型等。

The pace of urban construction is getting faster and faster in our country, and the economy of our country is developing continuously. This paper analyzes and discusses the grounding topology problems of the middle and low voltage distribution network in major cities in China. At the same time, it also studies some potential safety risks and conditions of 10 KV side contact voltage after 10 k V distribution network neutral grounding. And at the same time, according to the single area independent and multi area interconnected type of two types of ground grounding mode to design and establish the field road model and so on.
