Abstract

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.
