Abstract

The utility model relates to a clamping piece insulation structure for a transformer core and belongs to the technical field of transformers. The utility model adopts the following technical scheme: the clamping piece insulation structure comprises a clamping piece insulation body (4) and oil flow grooves (3), wherein the clamping piece insulation body (4) is arranged between a transformer core lamination (1) and a clamping piece (2), matched with the transformer core lamination (1) in size, adopts an integral structure and is made of an insulating material such as a whole piece of laminated wood or a whole piece of laminated paperboard; a plurality of oil flow grooves (3) are formed in the clamping piece insulation body (4) uniformly. The clamping piece insulation structure for the transformer core has the benefits as follows: the intensity of the clamping piece insulation body of the transformer core and transformer core clamping effect are improved, and the noises of the transformer are reduced.

Description

A kind of transformer iron core clamping piece insulation structure

Technical field

The utility model relates to a kind of transformer iron core clamping piece insulation structure, belongs to transformer technology field.

Background technology

Transformer core is mainly comprised of transformer iron core lamination, folder, arm-tie, fagging, feet, insulating part etc., transformer iron core lamination must come with other steel construction piece insulation, generally to place clamp insulation between transformer iron core lamination and folder, at present, this clamp insulation is all generally sticky cross-over block on insulating board, this clamp insulation is softer, transformer core is clamped to effect bad, also affects transformer noise.

Utility model content

The utility model object is to provide a kind of transformer iron core clamping piece insulation structure, adopts the insulating material such as monoblock lamination wood or laminated paper board, and is provided with stream oil groove, improves transformer core and clamps effect, solves the problem existing in background technology.

The technical solution of the utility model is: a kind of transformer iron core clamping piece insulation structure, comprise clamp insulation body and stream oil groove, clamp insulation body is located between transformer iron core lamination and folder, size matches with transformer iron core lamination, for overall structure, on clamp insulation body, be evenly provided with several stream oil grooves.

Described clamp insulation body adopts the insulating material such as monoblock lamination wood or laminated paper board.

The beneficial effects of the utility model are: improved transformer iron core clamping piece insulation structure intensity and transformer core and clamped effect, reduced transformer noise.
