Abstract
The utility model discloses a kind of dry-type power transformer, comprise high-tension coil and low-voltage coil, between described high-tension coil and described low-voltage coil, add resin-cast form an insulating cylinder.Forming an insulating cylinder by adding resin-cast between the high-tension coil and low-voltage coil of dry-type power transformer, avoiding the air gap adjusted in assembling process not mix up with this and puncturing coil, also can run in compared with the area surroundings of High aititude simultaneously.
Description
Technical field
The utility model relates to power transformer technical field, refers to a kind of dry-type power transformer especially.
Background technology
Dry-type power transformer in existing power equipment, generally can comprise high-tension coil and low-voltage coil, as as described in high-tension coil and as described in insulating barrier is not set between low-voltage coil, then creepage phenomenon can be produced, if the air gap adjusted in assembling process does not mix up and punctures coil, simultaneously because of air pressure reason, be also unfavorable for running in compared with the area surroundings of High aititude.
More existing patent documents disclose and solve the problems referred to above in different ways, if Chinese Authorization Notice No. is disclose a kind of dry-type power transformer in the utility model patent file of CN2872560Y, comprise grid and electromagnetic wire, described grid is between electromagnetic wire, epoxy resin is cast on electromagnetic wire by grid, in addition, China's publication number is that the patent of invention of CN101425366A discloses a kind of dry-type power transformer, between every phase winding of high pressure winding by upper and lower two independently winding form, separate with independently cross-over block between upper and lower winding.The insulation effect that is complicated or that reach of Method compare disclosed in above-mentioned two pieces patent is good not, and be not easy to realize in actual manufacture, time and effort consuming, is unfavorable for a large amount of production.
Therefore, be necessary to provide a kind of new dry-type power transformer, to solve the problems of the technologies described above.
Summary of the invention
The utility model object is to provide a kind of change dry-type power transformer, can prevent the air gap adjusted in assembling process from not mixing up and puncturing coil, also can run in compared with the area surroundings of High aititude simultaneously.
The technical solution of the utility model is achieved in that a kind of dry-type power transformer, comprises high-tension coil and low-voltage coil, adds resin-cast and form an insulating cylinder between described high-tension coil and described low-voltage coil.
Further, 2 1.2 grid cloths adopted inside described high-tension coil add resin-cast and are formed absolutely
Edge.
Further, 0.25D279 reinforced insulation is adopted outside described low pressure.
The utility model is compared with prior art: form an insulating cylinder by adding resin-cast between the high-tension coil and low-voltage coil of dry-type power transformer, avoid the air gap adjusted in assembling process not mix up with this and puncture coil, also can run in compared with the area surroundings of High aititude simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of insulating cylinder in the utility model dry-type power transformer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of dry-type power transformer, comprise high-tension coil and low-voltage coil, the air flue that dispels the heat (not shown) is provided with in high-tension coil in described high-tension coil, the air flue that dispels the heat is provided with in high-tension coil in described high-tension coil, in described low-voltage coil, be provided with in low-voltage coil the air flue that dispels the heat, the above is not shown.
As shown in Figure 1, add resin-cast between described high-tension coil and described low-voltage coil and form an insulating cylinder 1, wherein, 2 1.2 grid cloths adopted inside described high-tension coil add resin-cast and form insulation, adopt 0.25D279 reinforced insulation outside described low pressure.With this, between described high-tension coil and described low-voltage coil, form an insulating cylinder 1.
The utility model dry-type power transformer, an insulating cylinder is formed by adding resin-cast between the high-tension coil and low-voltage coil of dry-type power transformer, avoid the air gap adjusted in assembling process not mix up with this and puncture coil, also can run in compared with the area surroundings of High aititude simultaneously.Avoid the air gap adjusted in assembling process not mix up with this and puncture coil, also can run in compared with the area surroundings of High aititude simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
Claims (3)
