Three-phase electric energy meter auxiliary binding post

Abstract

The invention relates to a power device and particularly to a three-phase electric energy meter auxiliary binding post for facilitating the connection between an electric energy meter junction box and an electric energy meter and having high reliability. A phase-A connecting terminal, a phase-B connecting terminal, a phase-C connecting terminal, and an N null line connecting terminal are successively mounted on an auxiliary binding post pouring housing, and both ends of each terminal extend out of the electric energy meter side end face and the junction box side end face of the auxiliary binding post pouring housing. The three-phase electric energy meter auxiliary binding post, by means of the cooperation of the auxiliary binding post pouring housing, the phase-A connecting terminal, the phase-B connecting terminal, the phase-C connecting terminal, and the N null line connecting terminal, can conveniently connect the electric energy meter junction box with the electric energy meter. The three-phase electric energy meter auxiliary binding post is directly plugged when used and a corresponding fastening screw is screwed. Thus, complex wire connection is prevented and the three-phase electric energy meter auxiliary binding post is very convenient to use. Because winding connection is not required, junctions are not liable to deformation when wire connection is performed, thereby prolonging a service life and improving reliability.

Description

technical field [0001] The invention relates to electric equipment, in particular to a three-phase electric energy meter auxiliary terminal which is convenient for connecting the electric energy meter junction box with the electric energy meter and has high reliability. Background technique [0002] The three-phase watt-hour meter connected through the transformer must be installed with a watt-hour meter junction box for easy replacement. The wires are connected to the junction box first, and then the wires are connected to the three-phase watt-hour meter from the junction box. However, in work practice, it is found that the shorter the distance between the junction box of the electric energy meter and the electric energy meter, the more difficult it is to make the wire. And lead wire becomes irregular arrangement again after watt-hour meter separates with lead wire, and the copper wire on the lead wire is also deformed, and wiring lead will be changed after several times. ...

Problems solved by technology

However, in work practice, it is found that the shorter the distance between the junction box of the electric energy meter and the electric energy meter, the more difficult it is to make the wire.

Moreover, when the energy meter is separated from the wires, the wires are arranged irregularly, and the copper wires on the wires are also deformed. After several times, the wiring wires will be replaced.
