煤矿井下供电系统的区域选择性联锁保护的设计

Design of Area-selected Interlocking Protection of Underground Power Supply System

  • 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。

     

    Abstract: 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.
