矿用组合开关保护系统设计
Design of Mine－used Combined Switch Protection System
摘要
Abstract
In order to improve the safety and automation of coal mines and reduce the occurrence of downhole fault, a mine combined switch protection system was designed. The protection system includes leakage protection, short circuit protection and so on. At the same time, the intrinsically safe circuit is used for explosion prevention downhole, and RS485 is used for communication. The related hardware was built to test it and its feasibility was verified.关键词
