High-pressure-resistance mutual inductor shell

Abstract

The invention discloses a high-pressure-resistance mutual inductor shell. The shell comprises a first shell, a second shell is arranged at one end of the first shell, an annular shell is arranged in the middle end of the second shell, a through hole is formed in the center of the annular shell, a through hole is formed in the bottom end of the second shell, and rectangular blocks are arranged at the upper position and the lower position of one end of the first shell respectively. The high-compression-resistance mutual inductor shell is provided with a sliding block, a sliding groove, a triangular block, a triangular groove, a rectangular block, a rectangular groove and a connecting base. When the first shell and the second shell are assembled, the rectangular block is aligned with the rectangular groove; the rectangular block can be pushed into the rectangular groove; when the rectangular block touches the triangular block, the rectangular block extrudes the triangular block to move downwards to push the connecting base, and when the rectangular block drives the triangular groove to reach the position of the triangular block, a spring resets to bounce the triangular block into thetriangular groove to fix the rectangular block, so that the first shell and the second shell are mounted, the assembling efficiency is high, and the stability after assembling is high.

Description

technical field [0001] The invention relates to the technical field of transformer shell equipment, in particular to a high-pressure transformer shell. 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. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. [0003] When the existing transformer is installed and disassembled, it is easy to cause damage to the shell and is...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-pressure transformer shell to solve the problem that the existing transformer proposed in the above background technology is easy to cause damage to the shell when it is installed and disassembled, it is not easy to operate, and the steel sheet has transmission. Due to the characteristics of thermal conductivity, when the iron core winding is damaged, the power is easily transmitted through the steel sheet, which affects the normal operation of other power equipment.
