When there is a leakage or short circuit fault in the power supply system, methods such as rapid sampling and identification of fault signals, generation of power outage command pulses, and rapid power outage execution mechanisms are used. A comprehensive protection measure that quickly cuts off the power supply of the power supply network or cuts off the energy supply at the fault point through a power outage actuator. It is different from general relay protection and general electrical explosion-proof technology that only protects a single motor or electrical appliance (such as explosion-proof enclosures). Although it has equivalent safety performance to intrinsically safe circuits, it can be used in strong current circuits. When used in conjunction with other electrical safety and explosion-proof technical measures, the mine power supply system, including cables, can have overall fire and explosion-proof safety&Nbsp; All devices and scenarios that apply power supply involve the application of power outage protection function. For example, industrial safety production such as mines, electronic equipment such as computers, etc
