Pillar type bus current transformer

Abstract

The invention belongs to the technical field of transformers, and discloses a pillar type bus current transformer. The current transformer comprises a base and a current transformer main body, whereinthe current transformer main body is mounted at the top end of the base; two sides of the bottom end of the current transformer main body are symmetrically connected with screw rods; limiting blocksare symmetrically fixed to the lower surface wall of the current transformer body and located at the two sides of the screw. Through grooves matched with the screw rods are symmetrically formed in thetwo ends of the upper surface wall of the base; the limiting blocks are matched with the limiting grooves; when the base and the current transformer main body are connected, effective limiting can berealized, and offset can be avoided; in addition, through cooperation of a screw, a through groove and a hexagon nut, when the base and the current transformer body are fastened, the screw penetratesthrough the through groove and then is fastened through the hexagon nut, the connection stability of the base and the current transformer body can be effectively guaranteed, and loosening of the current transformer body is avoided.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a pillar type bus current transformer. Background technique [0002] A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Among them, the busbar current transformer is a low-voltage indoor A current transformer with bus-type casting insulation and plastic shell insulation, commonly known as a core-through current transformer. [0003] In the Chinese patent with the patent number CN201921697257.1, a pillar-type bus current transformer is disclosed. The patent describes that "by snapping the embedded block into the embedded groove, the inclined groove at the bottom of the embedded block squeezes the trapezoidal block until the embedding block is completely embedded in the bo...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a pillar-type bus current transformer to solve the problem of poor stability in the connection of the traditional current transformer through the base and the current transformer in the above-mentioned background technology. In addition, the connection block of the traditional current transformer It cannot be rotated, but can only be connected in a fixed direction
