Partial discharge high-frequency current transformer and preparation method thereof

Abstract

The invention discloses a partial discharge high-frequency current transformer and a preparation method thereof. The partial discharge high-frequency current transformer comprises two semi-circle magnetic cores which can be spliced into a circle, each semi-circle magnetic core is arranged in a corresponding magnetic core groove, the upper surface of each magnetic core groove is provided with a thin shell, the periphery of the upper surface of each magnetic core groove is provided with a plurality of anti-theft screw mounting holes at intervals, which are in one-to-one correspondence to the periphery of the corresponding thin shell, and screws are mounted in the anti-theft screw mounting holes so as to fix the thin shells on the magnetic core grooves; the outer sides of two end parts of each magnetic core groove are provided with limiting blocks, the two magnetic core grooves are buckled to form a circle, two end parts of one magnetic core groove are respectively fixed with two end parts of the other magnetic core groove through the limiting blocks, pin mounting holes are formed in the limiting blocks, and pins are arranged in the pin mounting holes to fixedly connect the limiting blocks. The partial discharge high-frequency current transformer disclosed by the invention has the advantages of preventing theft and guaranteeing use safety.

Description

Technical field [0001] The invention relates to the technology of the field of transformers, in particular to a partial discharge high-frequency current transformer and a preparation method thereof. Background technique [0002] Traditional current transformers mostly use hinges and buckles to achieve their portability and installation requirements, but the anti-theft effect is not ideal, and the hinges and buckles are easily corroded; in addition, the wiring terminals of traditional current transformers do not Protection is inevitably damaged by bumps during use or transportation, which affects the function of the transformer. This patent is based on solving the drawbacks of this industry, and on the basis of portability and corrosion resistance, it has anti-theft function and terminal protection function. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems and provide a partial discharge high-frequency current transfor...

AI Technical Summary

Problems solved by technology

[0002] Traditional current transformers mostly use hinges and buckles to meet their portability and installation requirements, but the anti-theft effect is not ideal, and the hinges and buckles are easily corroded and damaged; in addition, the terminal part of the traditional current transformer has no Protection, it is inevitable that it will be bumped and damaged during use or transportation, which will affect the function of the transformer
