Converter heavy current output and mutual inductor wiring, mounting and fixing device

Abstract

The invention relates to a converter heavy current output and mutual inductor wiring, mounting and fixing device. The device includes an integrated converter and a transformer, wherein the integratedconverter and a transformer casing body are provided with a primary input terminal, a 100A current output terminal, a current output common terminal and metal screws, a voltage and current gear switching circuit board is detachably disposed on the surface of the integrated converter and the transformer by the metal screws, a current mutual inductor is disposed on the voltage and current gear switching circuit board, the current mutual inductor has a current mutual inductor center hole, the 100A current output terminal penetrates through the current mutual inductor center hole and is fixed on the voltage and current gear switching circuit board through a short circuit copper bar, and the short circuit copper bar is connected with the current output common terminal through a 100A current relay. The device is advantaged in that utilizing a thick wire with a large current to wind the mutual inductor for later wiring in the routine technology is omitted, and production efficiency and cleanliness inside products are greatly improved.

Description

technical field [0001] The invention relates to the technical field of electric energy measurement, and more particularly relates to a device for connecting, installing and fixing a large current output of a converter and a transformer in an AC test power supply. Background technique [0002] With the development of the market economy and the reform of the electric power system, a new management mode of centralized inspection and unified distribution of electric energy metering devices has been formed, which puts forward higher requirements for the verification speed of electric energy metering devices. The energy meter is a measuring instrument under the state's key management. It is the basis for the settlement of electricity charges between power companies and users. It involves thousands of households and is of great significance to the national economy and people's livelihood. Moreover, since the electric energy meter is a measuring instrument with a large amount of use...

AI Technical Summary

Problems solved by technology

[0003] However, the current AC test power supply usually uses thick wires with high currents to wind the transformers after the high-current connection between the high-current output of the converter and the transformer, so the product production is slow and the process is complicated. Man-made faults are likely to be caused when winding large-current thick wires in the later stage, which increases the difficulty of product production and delivery time of products, and the production efficiency is low, which is not conducive to large-scale and rapid market occupation of products
