Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing and embodiment:

[0024] Such as figure 2 The shown base pressing device for a dry-type transformer coil includes a clamp 1 connected to the iron core 4 of the transformer, a base assembly 2 connected to the clamp 1, and the transformer coil 3 is pressed against the base on component 2.

[0025] Such as image 3 As shown, specifically: the base assembly 2 includes a base cap 20, a base 21, at least one base adjustment block 22, at least one base post 23, and an insulating cushion 24 disposed at the bottom of the base post 23 . The base cap 20 is connected to the clamp 1, and can be connected to the clamp 1 through its own locking device; the base 21 is sleeved inside the base cap 20, and the two are connected by threads. The base 21 has a Cavity; the position base adjustment block 22 can choose elastic parts, such as rubber or silicon rubber, and its quantity and si...

Abstract

The invention relates to a base compacting device of a dry-type transformer coil. The device comprises a clamping piece connected to an iron core of a transformer and a base component connected to the clamping piece, wherein the transformer coil props against the base component which comprise a base cap, a base seat connected with the base cap, at least one base regulation block, at least one base column and an insulation buffer arranged at the bottom of the base column; and the base seat is provided with a cavity, and the base regulation block is compacted in the cavity of the base seat by the base column. According to the invention, a height-adjustable combined modularized compacting device is utilized, so that each part of the base component can be realized in a standardized manner, and the product differentiation is reduced, thereby being suitable for transformers of various models; and the base component can be used for respectively compacting high-voltage and low-voltage coils, prolonging the creeping distance between the high-voltage and low-voltage coils to the greatest extent, and greatly saving the mold cost required by an original epoxy resin cushion block.

Description

technical field [0001] The invention relates to a dry-type transformer, in particular to a base pressing device for a dry-type transformer coil casted by epoxy resin. Background technique [0002] At present, between the epoxy resin cast transformer coil and the iron core, the high and low voltage coils are compressed by fixed iron pads or rubber pads or epoxy resin pads and metal nails. The structure can refer to figure 1 Shown: including the clamp 1 connected to the iron core of the transformer, the transformer coil 3, the epoxy resin pad 5 is connected to the clamp 1 through the metal nail 6, and the upper part of the transformer coil 3 is pressed on the epoxy resin pad on block 5. [0003] Now refer to the Chinese patent "coil pressing device" with the announcement number CN2773873Y, which includes clamps, pressing nails and spacers. A pressing plate with positioning holes is welded under the clamping parts. , the upper part of the pressure sleeve is a spare moth...
