摘要
Abstract
Short circuit under the mine often leads to ground substation tripping, namely override tripping, causing down-hole blackouts, which seriously influence the coal mine safety. Based on the characteristics of coal mine power supply system, the paper analyzes and summarizes the causes of the above short circuit trip,we put forward the scheme of using intelligent substation area to prevent tripping, which proves to be good after the practical application in coal mine.关键词
