Abstract
The utility model discloses a dry type transformer comprising a protection shell and a transformer body, wherein the transformer body comprises an iron core, a low voltage winding and a high voltage winding, colloid is filled in the gap between the transformer body and the protection shell, a layer of heat resistant isolating film is covered on the surface touching the colloid of the transformer body, and aramid paper insulating layers are arranged between the iron core and the low voltage winding, between the layers of the low voltage winding and between the turns of the high voltage winding. According to the utility model, the isolating film is arranged on the surface in direct contact with the colloid of the transformer body to isolate the colloid from the transformer so as to conveniently strip the colloid, and the aramid paper insulating layers are arranged between the iron core and the low voltage winding, between the layers of the low voltage winding and the coils of the high voltage winding, so that the dry type transformer has good insulating effect, small size and low production cost.
Description
Technical field
The utility model belongs to the transformer technology field, is specifically related to a kind of dry-type transformer.
Background technology
The heat dissipation problem of dry-type transformer all is one of problem of primary study all the time.The at present heat radiation of dry-type transformer is by towards housing, and be arranged in the space between the transformer in the housing and pour into liquid state colloid, after cured, by the colloid that solidifies heat is delivered to large-area housing, in time leaves, but such be arranged on that transformer breaks down or when needing maintenance, must peel off first the colloid that is filled between transformer body and the housing, but in stripping process, may damage the part of transformer inside, be unfavorable for maintenance and the maintenance of transformer; Dry-type transformer can increase the distance of winding in the dry-type transformer usually in order to guarantee enough electrical strengths again, but the volume of dry-type transformer is increased accordingly, increases cost, and insulation effect is undesirable.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of dry-type transformer is provided, and it has preferably thermal diffusivity and insulating properties, and is convenient to maintenance and maintenance.
The technical scheme that the utility model adopts is: a kind of dry-type transformer; comprise containment vessel and transformer body; described transformer body comprises iron core, low pressure winding, high pressure winding; be filled with colloid in the gap between described transformer body and the containment vessel; be covered with the heat-resisting barrier film of one deck on described transformer body and the surface that colloid contacts, between described iron core and the low pressure winding, between described low voltage winding layer and the high pressure winding inter-turn be equipped with the aramid paper insulating barrier.
As preferably, described barrier film is polymethyl, and thickness is the 0.6-0.8 millimeter.
The beneficial effects of the utility model are: the utility model is provided with barrier film on the surface that transformer body and colloid directly contact, so that colloid and transformer separate, be convenient to peeling off of colloid, when again building, barrier film can be pressed on the transformer body again, thereby eliminate the gap between barrier film and the transformer, reduced gap discharge, again by between iron core and low pressure winding, between low voltage winding layer and the high pressure winding inter-turn be equipped with the aramid paper insulating barrier, make it have preferably insulation effect, and volume is little, and production cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, containment vessel; 2, iron core; 3, low pressure winding; 4, high pressure winding; 5, aramid paper insulating barrier; 6, colloid; 7, barrier film.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
Embodiment: as shown in Figure 1; the utility model comprises containment vessel 1 and transformer body; described transformer body comprises iron core 2, low pressure winding 3, high pressure winding 4; be filled with colloid 6 in the gap between described transformer body and the containment vessel 1; be covered with the heat-resisting barrier film of one deck 7 on described transformer body and the surface that colloid 6 contacts; described barrier film 7 is polymethyl; and thickness is the 0.6-0.8 millimeter, between described iron core 2 and the low pressure winding 3, described low pressure winding 3 interlayers and high pressure winding 4 turn-to-turns are equipped with aramid paper insulating barrier 5.
The utility model is provided with barrier film 7 on the surface that transformer body and colloid 6 directly contact, so that colloid 6 separates with transformer, be convenient to peeling off of colloid 6, when again building, barrier film 7 can be pressed on the transformer body again, thereby eliminate the gap between barrier film 7 and the transformer, reduced gap discharge, again by between iron core 2 and low pressure winding 3, low pressure winding 3 interlayers and high pressure winding 4 turn-to-turns are equipped with aramid paper insulating barrier 5, make it have preferably insulation effect, and volume is little, and production cost is low.
