Electric energy meter fault simulation device and use method thereof

An electric energy meter fault simulation device and a use method thereof belong to the field of electric energy meters. Comprising an electric energy meter housing, a threaded cylinder, an outer frame, a backing plate, a connecting device and a control device. The electric energy meter shell is provided with an upper part and a lower part, and the inner wall of the electric energy meter shell is fixedly connected with a threaded cylinder; a base plate is fixedly connected to the inner wall of the outer frame; the base plate is located between the two electric energy meter shells, and the inner wall of the base plate is fixedly connected with a control device through a connecting rod. And the connecting device is inserted from the threaded cylinder on the shell of one electric energy meter, penetrates through the control device and then enters the threaded cylinder on the shell of the other electric energy meter. The electric energy meter shell can be opened or closed without dismounting and mounting bolts, s
