摘　　要：针对煤矿井下供电系统存在的越级跳闸问题,提出了一种新型的区域选择性联锁保护方案。该方案在现有的矿用开关上装一个智能控制模块,该智能控制模块与现有的保护装置的速断保护配合工作,实现了区域选择性联锁保护功能。试验结果表明,该方案成本低、可靠性高、安装方便,具有一定的实用性。To solve the problem of override skip existed in underground power supply system, the paper proposed a new type of area-selected interlocking protection scheme, that is, an intelligent control module is installed in mine-used switch and it works with instantaneous trip protection of existing protection device, so as to realize function of area-selected interlocking protection. The test result showed that the scheme has low cost, high reliability, easy installation, which has certain practicality.
