Research on Practical Technology for Overvoltage Protection of 35 kV Overhead Insulated Lines
This paper mainly discusses the current situation of overvoltage protection of 35 kV overhead insulated lines in an enterprise in Zaozhuang,and puts forward the line protection measures,such as protection gap,application of zinc oxide arrester and application of line overvoltage protector.Through statistics and evaluation of lightning protection effect,the weak points of lightning protection of overhead lines are accurately evaluated.At the same time,the lightning protection transformation scheme is put forward to ensure the safety of power supply and distribution and maintain the safety of electricity consumption in coal mines and other enterprises.By strengthening the overvoltage protection technology of 35 kV overhead insulated lines,the overvoltage protection goal can be realized and the orderly development of related enterprises can be promoted.
