Fixing device for transformer outlet copper bar and fixing method thereof

Abstract

The invention discloses a fixing device for a transformer outgoing copper bar and a fixing method thereof, belongs to the technical field of transformer outgoing copper bar fixing, and aims at achieving the limiting and fixing effects on two copper bar bodies and the fixing effect on the transformer outgoing copper bar bodies through cooperative use of a convex mounting plate and an insulating partition plate, and the insulation between the two copper bar bodies is achieved; the limiting plate with the heat dissipation mechanism is mounted on one side of the convex mounting plate through the fixed plate, and the fixed plate is mounted on the outer side of the convex mounting plate in an embedded mode, so that the fixed plate further plays a role in fixing the convex mounting plate and plays a role in supporting the limiting plate with the heat dissipation mechanism at the same time; the horizontal position of the limiting plate is adjusted according to the thickness of the copper bar body, the limiting plate drives the heat dissipation mechanism to abut against the outer side wall of the copper bar body, on one hand, the copper bar body fixing device is further suitable for fixingcopper bar bodies with different thicknesses, and on the other hand, the copper bar body is cooled through contact connection of the heat dissipation mechanism.

Description

[0001] The original application number of this divisional application is 201911108584.3, the application date is November 13, 2019, and the title of the invention is "A Fixing Device and Fixing Method for Transformer Leading Copper Bar". technical field [0002] The invention relates to the technical field of fixing copper bars of transformers, and more specifically relates to a fixing device for copper bars of transformers and a fixing method thereof. Background technique [0003] In the process of resin casting dry-type transformer winding, it can be divided into two processes: winding and pouring. The filling of the internal gap of the winding realizes the mechanical strength and electrical insulation of the structure after curing. For the leading copper bars of cast-type transformers, it is easy to touch the leading copper bars during the handling and pouring process to change the position of the copper bars, which will cause the finished coils cast out to fail to meet t...

Problems solved by technology

In the comparison document, the fixing plate used to fix the outgoing copper bar is welded on the outgoing line template. Although it plays a role in fixing the outgoing copper bar, this fixing method is too mechanically connected. When the outgoing copper bar is impacted by the outside , it does not have a good buffering effect on the copper bar at the beginning, and the comparison document only fixes the fixed plate on one side of the copper bar, and its fixing stability needs to be improved; in addition, the temperature of the finished coil will rise when it is working, making it The copper bar also has a certain high temperature phenomenon, and the fixed structure in the prior art only plays a role in fixing the copper bar, and the heat dissipation performance of the copper bar itself needs to be improved
