煤矿供配电系统中防越级跳闸保护技术

Protection Technology Against Skip Tripping in Coal Mine Power Supply and Distribution System

本文旨在研究煤矿防越级跳闸保护技术的选取和应用。根据项目背景,通过四种防越级跳闸保护技术选取方案对比,最终确定采用纤电流纵差保护方法,并对该方法的具体技术应用进行详细论述,最后进行了防越级跳闸保护实验,以验证所选取的防越级跳闸保护技术的有效性,研究结果为煤矿防越级跳闸保护提供了理论依据和实践指导。

This study aims to study the selection and application of anti skip tripping protection technology in coal mines.Based on the project background,through the comparison of four schemes of anti skip tripping protection technology selection,the fiber current longitudinal differential protection method was finally determined,and the specific technical application of this method was discussed in detail.Finally,anti skip tripping protection experiments were conducted to verify the effectiveness of the selected anti skip tripping protection technology.The research results provide theoretical basis and practical guidance for coal mine anti skip tripping protection.
