Three-phase pluggable electric energy meter

Abstract

The invention discloses a three-phase pluggable electric energy meter, which is characterized in that an electric energy meter body is connected with a base, a wire inlet wiring end and a wire outlet wiring end are respectively disposed at two ends of the base, a cylindrical wire inlet terminal and a cylindrical wire outlet terminal are disposed at the bottom of the electric energy meter body, a wire inlet jack corresponding to the wire inlet terminal of the electric energy meter body and a wire outlet jack corresponding to the wire outlet terminal of the electric energy meter body are arranged on the base, metal plugging sleeves are disposed in the wire inlet jack and the wire outlet jack, the metal plugging sleeve in the wire inlet jack is electrically connected with the wire inlet wiring end, and the metal plugging sleeve in the wire outlet jack is electrically connected with the wire outlet wiring end. The three-phase pluggable electric energy meter has the advantages that the three-phase pluggable electric energy meter is convenient in installation, installation, urgent repair and replacement time of the electric energy meter is effectively shortened on the basis of guaranteeing reliability, installation wiring parts of the electric energy meter are not exposed, and accordingly electricity stealing behaviors at the wiring parts can be effectively prevented.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to a three-phase plug-in electric energy meter. Background technique [0002] In the prior art, most of the electric energy meters adopt the wiring method, and it is usually necessary to manually connect the incoming and outgoing lines to the terminals of the electric energy meter one by one. This method has the following disadvantages: (1) Even if the electric energy meter is protected by a joint junction box, a terminal box and a seal, it is still inevitable that some electrical connecting wires are exposed, which provides opportunities for stealing electricity; (2) It is very inconvenient to install and connect, and it is necessary to check the line connections one by one, which not only requires a huge amount of labor, but also easily leads to wrong wiring; (3) When there is a problem that needs to be repaired, it is necessary to remove the incoming and outgoing lines befor...
