Discussion on the live line work of overhead line operating overhauling in the 10kV distribution network

Study on the Connection Mode of 10kV Distribution Network in Chongqing;

A simulation test circuit with lumped parameters is designed for the research on the characteristic of arc self-extinction caused by single-phase earth fault occurred in 10kV distribution network.

The article will analyze 10kV distribution network neutral point grounding mode of choice,and focused on the arc-suppression coil grounding superiority.

Research on hangzhou 10 kV distribution network closing loop operation;

Taking the development of 10 kV urban distribution network of Qingyuan,China for example,this paper analyzes the advantages and disadvantages of such connection schemes as radial type,loop and twin-mains of 10 kV distribution network.

The cable outlets for 10kV distribution network system are added and the network is continuously expanded,the system principle of the netural point though arc suppression coil grounding is analyzed.

By analyzing the circuit excited surger, the TV "unreal earth" phenomenon, TA saturation, the breaker switch coil easily being burned down,totally four frequent questions appearing to the operation and transformation of the railway 10 kV substation, puts forward the corresponding solutions.
