Abstract
The invention discloses an electric energy meter measuring box with electric energy comparison. The electric energy meter measuring box comprises a box body. An inlet line breaker, an outlet line breaker and an electric energy meter are installed in the box body. The electric energy meter is connected with the inlet line breaker and the outlet line breaker. A controller and a voltage transformer are installed in the box body. The controller is connected with the electric energy meter through an RS485 bus. The input end of the voltage transformer is installed between the inlet line breaker and the electric energy meter. The output end of the voltage transformer is connected with the controller. The breakers, the electric energy meter, the voltage transformer and the controller are installed in the box body. The voltage of the input end of the electric energy meter is detected by the voltage transformer, and the voltage detected by the voltage transformer is compared by the controller with the voltage of the electric energy meter. Thus, electric energy comparison is completed; a power supply department may timely grasp electric energy information, improves power quality and ensures the safety of electricity.
