Abstract

The utility model relates to a clamping piece insulating device of an amorphous alloy dry-type transformer. Aiming at the problems that the traditional insulating device is not capable of keeping a coil stable and is not capable of well dissipating heat, the performance parameter of the transformer drops because an iron core is stressed after the clamping piece insulating device runs for long term and the service life is shortened, the utility model provide the clamping piece insulating device of the amorphous alloy dry-type transformer. The clamping piece insulating device comprises a diphenyl ether plate and a plurality of thermoplastic elastomers, wherein the thermoplastic elastomers are evenly distributed at one side of the diphenyl ether plate to form a corrugated plate-shaped heat dissipation channel. The clamping piece insulating device is capable of effectively connecting the iron core and an upper clamping piece and a lower clamping piece of the transformer into a whole, so that the iron core is prevented from being stressed, the coil of the transformer is kept stable and the vibration when the transformer runs is effectively buffered; due to the fact that a heat dissipation structure is adopted, the iron core is capable of well dissipating the heat, and the overall performance of the dry-type transformer is powerfully kept. The clamping piece insulating device can be widely used for the dry-type transformer and is especially suitable for the amorphous alloy dry-type transformer.

Description

A kind of amorphous alloy dry-type transformer folder seal

Technical field

The utility model relates to a kind of folder seal, particularly a kind of amorphous alloy dry-type transformer folder seal.

Background technology

The iron core of amorphous alloy dry-type transformer is very responsive to mechanical stress, and the iron core folder is bent by iron plate, so need between coil and the iron core to play insulation and prevent the effect that iron core is stressed by a kind of device.Can produce vibrations when transformer normally moves, existing seal is can not hold-in winding stable, and can not well solve heat dissipation problem, easily causes iron core stressed and cause that the transformer performance parameter descends, service life reduces after the long-time running.

The utility model content

Technical problem to be solved in the utility model is: existing seal is can not hold-in winding stable, and can not well solve heat dissipation problem, easily causes iron core stressed and cause the problem that the transformer performance parameter descends, service life reduces after the long-time running.

The utility model solves the scheme that its technical problem takes and provides a kind of amorphous alloy dry-type transformer folder seal, comprise diphenyl ether plate 1, several thermoplastic elastomer (TPE)s 2, the side that several thermoplastic elastomer (TPE)s 2 are evenly distributed on diphenyl ether plate 1 constitutes heat dissipation channel 3, described heat dissipation channel 3 be shaped as corrugated plate shape.

A kind of amorphous alloy dry-type transformer folder of the utility model seal can be connected as a single entity iron core and transformer folder from top to bottom effectively, avoided iron core stressed, keep transformer coil stable, vibrations when having cushioned the transformer operation effectively, simultaneously owing to have radiator structure, make iron core to dispel the heat well, strong maintenance the overall performance of amorphous alloy dry-type transformer.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a kind of front view of amorphous alloy dry-type transformer folder seal;

Fig. 2 is a kind of left view of amorphous alloy dry-type transformer folder seal.

Accompanying drawing number is: 1. diphenyl ether plate, 2. thermoplastic elastomer (TPE), 3. heat dissipation channel.

Embodiment

By Fig. 1 and Fig. 2 as can be known the utility model solve the scheme that its technical problem takes and provide a kind of amorphous alloy dry-type transformer folder seal, comprise diphenyl ether plate 1, several thermoplastic elastomer (TPE)s 2, the side that several thermoplastic elastomer (TPE)s 2 are evenly distributed on diphenyl ether plate 1 constitutes heat dissipation channel 3, described heat dissipation channel 3 be shaped as corrugated plate shape.

Simultaneously for the stable of hold-in winding better and have better radiating effect, elastomer can be selected the SEBS thermoplastic elastomer (TPE) for use.

During use, the bonding firm back of diphenyl ether plate and thermoplastic elastomer (TPE) is fixed by the glass fiber strap.Effectively iron core and transformer folder from top to bottom etc. is connected as a single entity, keeps transformer coil stable, owing to adopt several thermoplastic elastomer (TPE) flexible splicings, be convenient to the iron core heat radiation, the vibrations in the time of also effectively cushioning the transformer operation; By the insulation of this folder, coil and folder from top to bottom are connected as a single entity, and have avoided iron core stressed, the overall performance of strong maintenance amorphous alloy dry-type transformer.
