Installation connecting assembly of oil-immersed transformer bus post insulator

Abstract

The invention discloses an installation connecting assembly of an oil-immersed transformer bus post insulator, which relates to the technical field of transformer bus post insulator installation. Theproblem of stability between a bus and an insulator post is solved. The installation connecting assembly specifically comprises a bottom plate, connecting holes distributed at equal intervals are formed in the outer wall of the bottom of the bottom plate, an insulator post is inserted into the inner wall of each connecting hole, the bottom end of each insulator post is sleeved with a flange base,and the outer wall of the top end of each insulator post is connected with a main mandrel through threads; the top end of each main mandrel is connected with a connecting column through a thread, andthe outer wall of the circumference of each connecting column is sleeved with a connecting piece. Through the arrangement of a first triangular stabilizing plate, a second triangular stabilizing plateand the connecting piece, the problem that the bus topples over under the action of oscillation force is solved, the stability between the insulator post and the bus is greatly enhanced, and the safety of the bus is guaranteed.

Description

technical field [0001] The invention relates to the technical field of installation of transformer bus post insulators, in particular to an installation and connection assembly of an oil-immersed transformer bus post insulator. Background technique [0002] Oil-immersed transformer refers to a transformer that uses transformer oil as the insulation and cooling medium. Transformer oil is a petroleum-based liquid, which has the possibility of burning and has disadvantages in terms of environmental protection. However, because transformer oil has the characteristics of excellent performance and low price, most power transformers still use transformer oil as insulation and cooling medium. In the process of using the transformer, it is necessary to install its busbar post insulators. [0003] After searching, the Chinese patent application number is CN201810787392.9, which discloses a transformer bushing busbar post insulator mounting bracket, including bracket mounting interfa...

AI Technical Summary

Problems solved by technology

[0004] Although the overall mechanism has achieved the installation of the busbar and the post insulator, the stability of the busbar when it is connected to the post insulator has not been fully considered. Therefore, when the transformer vibrates violently, the busbar and the post insulator will shake or even shift. problem, resulting in a decrease in the insulation effect
