摘　　要：近年来,在煤矿供电系统继电保护装置的持续更新与升级下,高压防爆开关在井下高压供电系统中的应用越来越广泛。为增强煤矿井下高压供电系统的灵敏度与可选性,深入分析煤矿井下高压供电保护整定计算方法,同时将企业的实践应用现状作为基础,灵活制定整定办法。In recent years,with the continuous updating and upgrading of the relay protection device of the coal mine power supply system,the application of high-voltage explosion-proof switch in the underground high-voltage power supply system is more and more extensive.In order to enhance the sensitivity and selectivity of high voltage power supply system in coal mines,the setting calculation method of high voltage power supply protection in coal mines is analyzed in depth.At the same time,the setting method is formulated flexibly based on the practical application status of enterprises.
