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

Abstract

The invention discloses a three-phase multi-station electric energy meter plug-in which is characterized by comprising an electric meter, a plug-in base and a signal thimble fixing box, wherein the plug-in base is a combined plug-in base formed with more than two identical plug-in base bodies in an integral forming mode, an insertion terminal is arranged on an insertion terminal fixing hole, the signal thimble fixing box is connected with the upper end face of the insertion terminal fixing box in a buckled mode, signal thimbles are assembled on the signal thimble fixing box and are connected with signal lines in a cold pressing mode, and the signal lines connected with the signal thimbles are led to ling grooves in the plug-in base through the signal thimble fixing box. A plug-in combination is designed to be a whole composed of two or more electric meter plug-ins, is connected with wiring terminals of electric meters in a straight plug mode, and is provided with electric meter installation guide grooves. The three-phase multi-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 three-phase multi-meter position electric energy meter plug-in. 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, save costs and reduce labor intensity of workers. Contents of the invention [0003] The purpose of the present invent...
