Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] Such as figure 1 , figure 2 As shown, a connecting fastener for a transformer includes a connecting base 2 and a connecting sleeve 1. The connecting base 2 and the connecting sleeve 1 are integrally injection-molded with epoxy resin, and the connecting base 2 and the connecting sleeve 1 are both cylinders. Shaped structure, the connection sleeve 1 is vertically located in the middle of the upper part of the connection base 2, and the diameter of the connection base 2 is greater than the diameter of the connection sleeve 1. A circular groove 3 is provided at the bottom of the connection base 2, and gaskets can be placed in the groove 3.

Abstract

The invention provides a connecting fastener for a transformer and relates to a connecting fixing device. The connecting fastener for the transformer comprises a connecting base and a connecting sleeve, wherein the connecting base and the connecting sleeve are integrally shaped from epoxy resin in an injection moulding way; the connecting base and the connecting sleeve are both of a cylindrical structure; a circular groove is formed in the bottom of the connecting base; a gasket can be arranged in the groove. Compared with the prior art, the connecting fastener for the transformer made from the epoxy resin on the whole never rusts, is convenient to manufacture and is good in insulativity; transformer equipment adopting the connecting fastener is good in insulating performance; the use is safe.

Description

technical field [0001] The invention relates to a connection and fixing device, in particular to a connection fastener for a transformer. Background technique [0002] The insulating fasteners used in the existing transformers are all metal or plastic injection molding, because the injection molding process is easy to produce tiny bubbles inside the fasteners, and it is not easy to check with the naked eye, this fastener is installed in the transformer Partial discharge will occur during medium operation, which will cause safety accidents and even damage the transformer for a long time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a connecting fastener for transformers with high insulation strength and long-term safe operation of the transformer. [0004] The technical problem to be solved by the present invention adopts the following technical solutions to realize, [0005] A connection fastener for a trans...
