摘要
在分析我国井下高压电网短路故障的基础上,深入研究相关保护原理及提高井下高压电网保护灵敏度和可靠性的方法,设计出基于CAN通信的井下防越级跳闸系统设计方案,从而做到快速的、有选择性的切断故障线路,避免煤矿井下高压电网因越级跳闸而造成大面积停电。
Based on the analysis of short-circuit fault on high voltage network in our country, Studied the theory of protection and the way of raising the reliability of protection in-depth,we designed a new method of over-current protection system based on CAN for underground high-voltage distribution, it can be fast, selective cutting fault lines, can avoid blackouts on large acreage which caused by overstep tripping in high-voltage distribution.
