Power failure auxiliary device with remote cost control function

The invention provides a power failure auxiliary device with a remote cost control function. The power failure auxiliary device comprises a cost control electric energy meter, an external switch, an intermediate relay and a circuit breaker, the cost control electric energy meter is electrically connected with one end of the external switch, the other end of the external switch is electrically connected with one end of the intermediate relay, and the other end of the intermediate relay is connected with the circuit breaker. According to the invention, the on or off of the electric energy meter is remotely controlled, and after the user pays the fees in time, the power supply can be remotely controlled to be supplied to the user in time, so that the problems of long time consumption in field operation and complaint in overtime power recovery are avoided. And the remote operation also avoids the electric shock risk of field operation. 本发明提供一种具有远程费控功能的停电辅助装置，包括费控电能表、外置开关、中间继电器和断路器；所述费控电能表与所述外置开关的一端电连接，所述外置开关的另一端与
