煤矿高压供电防越级跳闸技术研究现状与发展

Current Situation and Development of Anti-skipped Trip Technology in Coal Mine High-voltage Power Supply

越级跳闸现象严重威胁着矿井供电安全。针对目前煤矿井下常用的防越级跳闸方案进行了详细的分析比较,并提出了解决问题的新方案。智能联锁型保护新方案更加符合我国煤矿安全生产的现状,对煤矿安全供电具有实际指导意义。

The phenomenon of skipped trip is serious threat to the mine safety of power supply. This paper makes a detailed analysis on the current scheme on anti-skipped trip that commonly used underground, and also proposes a new solution： the intelligent interlocked protection, which fits coal safety production of our country better and has practical guiding significance to the safety of coal power supply.
