Abstract The advantages and disadvantages of the power supply network for information collection and transmission are explained through the detailed analysis of the operation principle and multi-level architecture of the secondary protection device in the high-voltage substation of the coal mine. The fault diagnosis types are divided and positioned, and the online state monitoring of the relay protection equipment and the real-time monitoring of the secondary circuit are analyzed. Finally, the fault points are quickly found through the fault location and investigation technology, and the information feedback is carried out to solve the hidden dangers in time, so as to realize the safe and reliable operation of the power supply network in the coal mine.
