Embodiment Construction

[0013] A specific embodiment of the insert support bracket of the present invention, such as image 3 shown. figure 1 It shows the use state diagram of the insert support bracket, 1 is the insert, 2 is the bracket, 3 is the secondary winding, and the insert 1 is provided with a ring groove 11 . The insert support bracket 2 includes a bracket base 21 , two side support plates 22 , and four support guide grooves 241 . The bracket base 21 includes two installation support plates 24 and a web connected between the two installation support plates 24. The guide slots 241 and the support guide slots 241 are U-shaped, and the openings of the four support guide slots 241 face the web and are in the same direction as the curing and shrinkage of the epoxy resin at their positions. Both sides of the web of the bracket base 21 are symmetrically provided with side support plates 22, in order to increase the contact area between the insert support bracket 2 and the secondary winding 3, so ...

Abstract

The invention discloses a supporting bracket for an inserting piece. The supporting bracket comprises a platelike bracket base body, wherein the bracket base body comprises two mounting supporting plates and a web plate connected between the two mounting supporting plates; the bracket base body is I-shaped; supporting guide grooves for mounting the inserting piece are formed in two sides, deviated from the web plate, of the mounting supporting plate respectively; and openings of the supporting guide grooves face the web plate. Compared with the prior art, the supporting guide grooves with the openings facing the web plate are formed in the supporting bracket for the inserting piece, the inserting piece is mounted in the supporting guide grooves, a secondary winding is mounted below the supporting bracket for the inserting piece, and the supporting bracket, the inserting piece and the secondary winding are put in a mold for pouring epoxy resin. When the epoxy resin is cured and shrunk, the epoxy resin drives the inserting piece to move towards the central part along the supporting guide grooves, so that relative movement is not generated between the epoxy resin and the inserting piece, and the epoxy resin on the periphery of the inserting piece does not crack.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an insert support bracket. Background technique [0002] As one of the important components of electrical equipment, transformers include secondary coils, which mainly transmit information to measuring instruments, meters or protection devices. At present, in the production process of most transformers, the secondary coil is fixed firmly with the fixed bracket, and the fixed bracket and the insert of the transformer are connected by welding. The brackets are fixed together on the mold with inserts, and epoxy resin is poured to hold the three together. Such as figure 1 and 2 As shown, 1 is an insert, 2 is a bracket, and 3 is a secondary coil. The insert 1 is a standardized product, and two ring grooves 11 are arranged on it. The bracket 2 includes a bracket base 21 and two side support plates 22. The bracket base 21 is generally I-shaped, and the two sides of the middle ...
