Problems solved by technology

However, in actual work, the space of the metering room is small, the wiring length between the electric energy meter and the junction box is limited, the wiring harness is close to the mounting plate, and the 4mm 2 The hardness of the copper core wire is relatively strong, which requires high finger strength of the operator, and the pure manual wiring process cannot be guaranteed
In the inspection process of the new installation of the metering device, when a wiring error occurs, the situation occurs between the electric energy meter and the joint junction box. In this way, rewiring is required, which is time-consuming and laborious

Embodiment 1

[0029] A standard wiring device for electric energy meters, the device includes a motherboard 1 and a sub-board 2 fixedly connected to the motherboard 1, the motherboard 1 adopts a rectangular insulating board with a size of 30cm×4cm×0.5cm, and the motherboard 1 is provided with ten The fulcrum holes 4 of the motherboard are 0.3cm in diameter, and the ten fulcrum holes are arranged on the motherboard 1 in three layers. Among them, three fulcrum holes are arranged horizontally on the first layer, which are connected with the electric energy meter U in turn. The current inlet, voltage wire, and current outlet are vertically corresponding; the second layer is horizontally equipped with three motherboard fulcrum holes, which are in turn vertically corresponding to the current inlet, voltage wire, and current outlet of the V phase of the electric energy meter; The third layer is horizontally equipped with four motherboard fulcrum holes, which are in turn vertically corresponding to ...

Embodiment 2

[0034] A standard wiring device for electric energy meters, the structure of which is as described in Embodiment 1, the difference is that, in order to avoid wrong wiring, digital wiring signs or engraved numbers are correspondingly pasted below the fulcrum holes of the mother board and the fulcrum holes of the sub-board Wiring identifier symbols. In this way, during the wiring process, the operator can perform wiring according to the digital wiring marks, which ensures the accuracy of wiring.

Embodiment 3

[0036] The method of using the standard wiring device of the electric energy meter to connect the three-phase four-wire electric energy meter in the metering room includes the following steps,

[0037] (1) Insert the opening slot 3 on one side of the sub-board 2 into the junction box, so that the fulcrum hole 5 of the sub-board is perpendicular to the three outlets of each phase of U, V, and W on the junction box and the neutral line hole correspond;

[0038] (2) Loosen the bolts, pull the mother board 1 through the chute 6, adjust the relative position of the mother board 1 and the daughter board 2, place the mother board 1 under the electric energy meter, and make the main board fulcrum hole 4 align with the electric energy meter in turn The three outlets of each phase of U, V, and W on the board are vertically corresponding to the zero line hole, and the bolts are tightened to fasten the mother board 1 and the daughter board 2 together;

[0039] (3) Use a screwdriver to in...

Abstract

The invention relates to an electric energy meter standard wiring device and a using method of the electric energy meter standard wiring device. The device comprises a main plate and an auxiliary plate connected with the main plate through a sliding groove. The main plate and the auxiliary plate are each provided with ten supporting point holes formed three layers in a staggered mode, wherein the first layer is provided with three supporting point holes, the second layer is provided with three supporting point holes, and the third layer is provided with four supporting point holes. An open groove is formed in one side of the auxiliary plate. In the using process, a wiring box is clamped inside the open groove of the auxiliary plate, and the relative positions of the auxiliary plate and the main plate are adjusted through the sliding groove so that the supporting point holes in the main plate and the auxiliary plate can perpendicularly correspond to three wire outlet openings and null wire openings of each of a U phase, a V phase and a W phase of an electric energy meter and wire outlet openings and null wire openings of each of a U phase, a V phase and a W phase of the wiring box. A screwdriver or other tools is / are inserted into the supporting point holes for bending wires so that the electric energy meter can be connected with the wiring box. After auxiliary wiring by the utilization of the device, wiring is neat and attractive, the construction technology is regulated, meanwhile, the labor intensity of workers can be effectively relieved, and working efficiency is improved.

Description

technical field [0001] The invention relates to a standard wiring device for an electric energy meter and a method for using the same, and belongs to the technical field of electrical auxiliary equipment. Background technique [0002] At present, the energy meters and junction boxes used in the power supply field have been standardized, and their specifications and sizes have been unified. There are "20 folded line bends + 10 wires" between the electric energy meter and the junction box. According to the requirements of the "State Grid Corporation of China Metrology Standardization Work Instructions", the wiring must be layered and phase-separated, horizontal and vertical, and the bending angles are uniform. [0003] In recent years, the expansion and new installation of the electric power industry has shown the characteristics of small capacity and multi-point public power supply construction, which makes the site of electric energy metering work more diverse and wide, and ...
