DEVELOPMENT OF MEASURES ON INCREASE OF ACCIDENT RATE OF 1150 kV LINES OWING TO LIGHTNING

By Oleg Alexandrovich Nikitin

Abstract

The investigation objects are the power lines with voltage 500, 750 and 1150 kV. The aim is to determine the basic causes of the accidental switching-off of 1150 kV lines and to substantiate scientifically the measure complex on the increase of their reliability. It has been determined that the determining number of accidental switching-off in 1150 kV lines takes place owing to the ligthning breaks through the earth-wire. The perspectivity of using artificial-charged aerosole clouds for the line lightning protection modelling has been shown. The prinbciples for organization of the wave process recording system on 1150 kV line enabling to determine the places of lightning shocks and short circuit have been developed. The investigation results on the reliability of the super-high voltage (SHV) power lines are used at improvement of the lightning protection in the Kazakhenergo and Belarusenergo. Application field: super-high and ultra-high voltage power linesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
