摘　　要：差动保护装置是煤矿通信常用的保护设备,尽管差动保护装置属于电气设备,但差动保护的功能发挥对维持煤矿通信的稳定运行有着重要的作用。针对这一点,阐述了煤矿通信设备内部差动保护装置的原理及功能结构。Differential prote, ction device is commonly used in coal mines to protect communications equipment, although differential protection devices are electrical equipment, but the differential protection function to play in maintaining the stable operation of coal traffic has an important role. On this point, this paper focuses primarily on coal mining communications equipment internal differential protection principle and functional structure.
