煤矿井下继电保护系统的研究

摘要

本文介绍了煤矿井下继电保护的基本任务与要求，通过对钱家营矿井下三采区变电所变压器短路电流的计算、继电保护的整定，针对性的提出了煤矿井下采区变电所开关继电保护的方法。%This paper describes the coal mine and the protection of the basic tasks required by the calculation Third District Substation Qianjiaying mine under short-circuit current of the transformer, relay tuning, targeted coal mine proposed mining area substation relay protection switching method.
