Mutual inductor with stable fixing structure

Abstract

The invention relates to the technical field of mutual inductor installation, in particular to a mutual inductor with a stable fixing structure. The mutual inductor comprises a mutual inductor shell, a circular ring inner cavity of the mutual inductor shell is set as an installation inner cavity, a heat dissipation boss is arranged in the middle of the upper end of the mutual inductor shell, and a plugging base is arranged at the lower end of the mutual inductor shell. The mutual inductor has the beneficial effects that by arranging the sliding mounting block, the left and right mounting and fixing positions are matched with the interval between the adjacent circuits, the mounting and fixing range of the mutual inductor is widened, the mounting stability of the mutual inductor is greatly enhanced, and meanwhile, the pressing change of a U-shaped pipe is utilized to realize extrusion and fixation of the sliding position; through the cooperation of the pull rod and the plugging frame, the connection position of the binding post is pressed and fixed, so that the stability of circuit connection is improved, through the cooperation of the extrusion screw rod and the locking nut, the wiring position is conveniently disassembled, and the installation efficiency of the mutual inductor is greatly improved.

Description

technical field [0001] The invention relates to the technical field of transformer installation, in particular to a transformer with a stable fixed structure. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and high current into small current for measurement or protection system. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change.

AI Technical Summary

Problems solved by technology

[0003] The two sets of coils on the transformer are used to connect different circuits, so that the transformer cannot be adapted to the distance between adjacent circuits during actual installation, which makes the installation of the transformer in adjacent circuits more difficult. At the same time, the existing transformer terminal lacks a fixing device when it is connected to the circuit, and the single connection terminal socket is easy to fall off during the actual test, resulting in a decrease in the stability of the circuit connection

[0004] For this purpose, a transformer with a stable fixed structure is provided to solve the installation and connection problems of the transformer between adjacent circuits
