Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, mutual inductors, contactors, etc. The operation process of power equipment generally requires corresponding protective devices or switches to effectively avoid the occurrence of safety accidents. The power-off protection device for commercial refrigerators is a device specially designed to protect commercial refrigerators when power is off.
