Three-phase single-station electric energy meter plug-in

Abstract

The invention discloses a three-phase single-station electric energy meter plug-in which is characterized by comprising an electric meter, a plug-in base, a set of control switches and a signal thimble fixing box, wherein the control switches, the signal thimble fixing box and the electric meter are sequentially arranged on the plug-in base, signal thimbles are disposed on the signal thimble fixing box and are connected with signal lines in a cold pressing mode, the signal lines connected with the signal thimbles are led into line grooves in the plug-in base through the signal thimble fixing box, and the control switches are connected with insertion terminal lines. The three-phase single-station electric energy meter plug-in is simple, convenient and fast in wiring, greatly saves labor, materials and cost, and is high in price performance ratio.

Description

technical field

[0001] The invention relates to an electric energy meter, in particular to a plug-in for a three-phase single-meter electric energy meter. Background technique

[0002] With the transformation of the national grid, the smart grid is vigorously promoted, and the consumption of electric meters, meter boxes and air switches is greatly increased. At present, the electric energy meters and air switches in the meter boxes are connected by screws and wires. The more meter positions, There are more connecting wires, and the wiring of the internal connecting wires is complicated. At the same time, the signal control wire of the electric energy meter is also connected by manual screws, which is more complicated and easy to connect wrong wires. The labor intensity of wiring workers is high and the efficiency is low. In order to solve such problems, the electric energy meter plug-in is developed to save costs and reduce labor intensity of workers. Contents of the inven...
