Electrical secondary line quick connector

Abstract

The invention discloses an electric secondary line quick connector which comprises a chassis, wherein a positioning set which is composed of multiple positioning pins is arranged on a chassis surface of the chassis, and the positioning pins are arranged on the chassis according to a secondary equipment wiring position. A length marking and a movable scale are arranged on the chassis surface of the chassis, the movable scale is connected with the chassis by a pin shaft, and the movable scale can rotate on the chassis surface along the pin shaft. The electric secondary line quick connector is mainly used for wiring of the electric secondary equipment, the length of a joint can be calibrated by the length marking and the movable scale, and wiring position and guide line bending can be quickly calibrated by a positioning pin. Secondary wiring is conducted by the electric secondary line quick connector through an experiment, so that wiring accuracy can reach 100%, and average working time is shortened by 12.5% compared with existing wiring. Not only is damage due to line misconnection avoided, but also working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of electrical secondary line wiring appliances, in particular to an auxiliary tool for quick connection of secondary lines. Background technique [0002] In the power system, secondary equipment such as transformers and meters are connected together with lines according to their functional requirements according to a certain layout to form a secondary circuit. The wiring of the existing secondary wires is purely manual. One method is to wire a single wire first according to the size and layout of the internal surface and terminals of the secondary equipment, and then bind multiple wires into a bundle after connecting them to the device. This method has a high rate of wiring accuracy, but after a single connection, it is troublesome to bundle, takes a long time, and the wire bundle is irregular, sometimes failing to meet the requirements of the wiring specification. Another method is to cut and bind the wire...

AI Technical Summary

Problems solved by technology

The problem is that after multiple wires are bundled, due to the large number of wire ends, it is difficult to check the wires during wiring, which takes a long time and is prone to errors

According to statistics, the average wiring time of existing electric energy metering devices is 200 minutes, and the correct wiring rate is 99%. There are nearly 20,000 faults caused by wiring errors in the country every year, causing direct economic losses of hundreds of millions of yuan.
