A mounting plate is arranged in the main box body, a sets of electric energy meters are arranged in the mounting plate, one side of the main box body is hinged to the protective housing through a connecting shaft, the rear portion of the main box body is connected with a wire inlet box, the upper portion of the wire inlet box is provided with a support, and the top of the support is provided with a water chute. One side of the wire inlet box is provided with a bent sleeve, the interior of each of the main box body and the protective housing is provided with a loudspeaker, one side of each loudspeaker is provided with a contact switch, the side of each loudspeaker is provided with a conductive spring matched with the contact switch, and each contact switch is electrically connected with a control chamber loudspeaker. The electric energy metering box protective device can protect the electric energy meters well, can prevent irrelevant personnel from turning off electric brakes of users at will, can give an alarm when being treated violently, and is high in safety.

Description

technical field [0001] The invention relates to the field of protection devices, in particular to a protection device for a metering box of an electric energy meter. Background technique [0002] Electric energy metering box is a commonly used power equipment for measuring electricity consumption. It is widely used in various places such as residential areas and office buildings. In some bungalow residential areas and low-rise buildings, it is often used to set the electric energy metering box outdoors. It is difficult to avoid the situation that the electric energy metering box is drenched by rain. At the same time, no matter whether the electric energy metering box is installed in the building or outdoors, the electric energy metering box is maliciously damaged from time to time, and pranksters will open the electric energy metering box. The circuit breaker is pulled down, causing some users to be unable to use electricity normally. Now a protective device for the electric...
