Abstract
A clamping member insulating structure of an iron core reactor in the field of transformer parts comprises an insulating web and a cushion blocks. The insulating web and the cushion blocks are fixedly connected with each other, each cushion block is elongated, the cushion blocks are parallelly arranged on the insulating web, the inside of each cushion block is of a cavity structure, sectional shape of each cavity structure is rectangular, and the length direction of each cavity structure is perpendicular to the insulating web. By adopting the cushion blocks of the cavity structures, radiating area of an iron yoke is increased, so that conducting and radiating efficiency is improved, temperature of the iron yoke is lowered, aging process of contact insulating is delayed, and product service life is prolonged.
Description
Technical field
The utility model relates to the structure in a kind of transformer part field, specifically a kind of clamp insulation structure of iron-core reactor.
Background technology
At present in conventional iron-core reactor product, clamp insulation adopts epoxy plate to form, and what adopt is solid epoxy cushion block, solid and expoxy glass silk fabric board, heat-conductive characteristic, area of dissipation are smaller, the heat conducting and radiating efficiency of iron yoke is lower, and iron yoke temperature is higher, and contact insulation can accelerated ageing with it.
Through the retrieval of prior art is found, Chinese patent literature CN202996521, open day 2013.06.12, recorded a kind of dry type transformer clamp insulation, comprise insulation web and be arranged at the cushion block on insulation web, the tail end of described insulation web has additional end cushion block, and forms and can hold the container cavity for the back-up block of support coils between end cushion block and immediate cushion block.But the prior art does not solve the heat conduction that strengthens iron yoke, improve the problem of iron yoke radiating efficiency.
Utility model content
The utility model, for prior art above shortcomings, proposes a kind of clamp insulation structure of iron-core reactor, has strengthened radiating efficiency and the useful life of product.
The utility model is achieved through the following technical solutions, the utility model comprises: insulation web and some cushion blocks, wherein: cushion block is strip, be parallel to each other and be fixed on insulation web, every two cushion blocks are one group, the inside of cushion block is cavity structure, and the cross sectional shape of this cavity structure is rectangle, and its length direction is vertical with insulation web.
The spacing of adjacent two cushion blocks is 5～15mm, is preferably 10mm.
Described cushion block is that metal material is made.
Length on the cross section of described cavity structure is greater than 10mm, is highly greater than 5mm.
The utility model adopts the cushion block of cavity structure to increase iron yoke area of dissipation, thereby has improved heat loss through conduction efficiency, has reduced iron yoke temperature, has delayed the ageing progress of contact insulation, has improved product and has used degree of safety, has extended the life-span of product.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the cavity structure sectional view of cushion block;
Fig. 3 is the installation diagram of the utility model and iron yoke.
Embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed execution mode and concrete operating process, but protection range of the present utility model is not limited to following embodiment.
Embodiment 1
As shown in Figure 1, the present embodiment comprises: the insulation web 1 being mutually permanently connected and cushion block 2, and wherein: cushion block 2 is metal material, strip structure, is parallel on insulation web 1, and every two cushion blocks 2 are one group.As shown in Figure 2, the inside of cushion block 2 is cavity structure 3, has increased iron yoke area of dissipation, the cross sectional shape of this cavity structure 3 is rectangle, its length direction is vertical with insulation web, makes air axially to realize convection current at cushion block 2, has further improved cooling-down effect.
The spacing of adjacent two cushion blocks 2 is 10mm, and the object of its spacing setting is to mate the frequency of iron yoke coil, makes cushion block because the induced current that electromagnetic induction produces is minimum.
Described cushion block 2 is made for metal material.
Length L on the cross section of described cavity structure 3 is greater than 10mm, and height H is greater than 5mm, and the object that arranges of this size is to make cushion block because the induced current that electromagnetic induction produces is minimum.
The web 1 that insulate in the present embodiment adopts epoxy plate.
As shown in Figure 3, the present embodiment is arranged at the both sides of iron yoke, by folder, is fixed for the present embodiment and iron yoke assembly structure.
