Abstract

The utility model provides a dampproofing dry -type transformer, includes the iron core, the iron core be equipped with low voltage winding, insulating layer and high voltage winding from inside to outside respectively, the iron core on the lower extreme all be equipped with the grip block, the high voltage winding outside be equipped with the dampproofing pipe of a plurality of, dampproofing pipe including toasting pipe and aspiration channel, toast pipe and aspiration channel on all be equipped with a plurality of gas pocket, grip block upper portion be equipped with hair -dryer, suction fan and controller, blow fan air outlet through heating device with toast a tub intercommunication, suction fan and aspiration channel intercommunication. The utility model overcomes prior art's is not enough, toasts pipe and aspiration channel outside setting of transformer coil, toasts hot -blast moisture to attached to on the coil that the pipe blew off and adds stoving and bake, and the aspiration channel siphons away the vapor after the heating, has effectually prevented that moist weather iron core, high low voltage coil from weing and leads to the emergence of insulation resistance phenomenon on the low side, has ensured the operation of transformer safety and stability, has prolonged life.

Description

A kind of moistureproof dry-type transformer
Technical field
The utility model relates to Dry-Transformer Technology field, specifically belongs to a kind of moistureproof dry-type transformer.
Background technology
The places such as dry-type transformer is widely used in localized lighting, skyscraper, airport, harbour CNC plant equipment, briefly dry-type transformer just refers to that iron core and winding are not immersed in the transformer in insulating oil.The type of cooling is divided into natural air cool (AN) and force Air flow (AF).During natural air cooling, transformer can run continuously for a long time under rated capacity.During forced air cooling, transformer output capacity can improve 50%.Be applicable to interrupted running overload, or emergent accident running overload; Because load loss during overload and impedance voltage amplification are comparatively large, are in non-economy running status, therefore it should not made to be in long-time continuous running overload.
Due to the difference of weather in all parts of the country, comparatively moist in many microclimates, different problems will be run into when using transformer, ambient air humidity is larger through moisture, transformer makes moist and easily causes insulation resistance on the low side, and major embodiment is iron core, high-voltage coil and low-voltage coil makes moist causes insulation resistance on the low side.
Utility model content
The purpose of this utility model there is provided a kind of moistureproof dry-type transformer, overcome the deficiencies in the prior art, at transformer coil outer setting baking pipe and aspiration channel, the hot blast of baking pipe blowout carries out heated baking to the moisture be attached on coil, aspiration channel siphons away the steam after heating, effectively prevent wet weather iron core, high-voltage coil and low-voltage coil makes moist and cause the generation of insulation resistance phenomenon on the low side, ensured and the operation that transformer safety is stable extended useful life.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of moistureproof dry-type transformer, comprise iron core, described iron core is respectively equipped with low pressure winding, insulating barrier and high pressure winding from inside to outside, described iron core upper and lower side is equipped with grip block, described high pressure winding outside is provided with several moistureproof pipes, described moistureproof pipe comprises baking pipe and aspiration channel, described baking pipe and aspiration channel are equipped with several pores, described grip block top is provided with hair-dryer, induced-draught fan and controller, described hair-dryer gas outlet is communicated with baking pipe by heater, and described induced-draught fan is communicated with aspiration channel.
Further, several described moistureproof pipes are fixed between upper and lower grip block, annular array centered by core center line.
Further, described high pressure winding outside is provided with humidity sensor, and described humidity sensor signal output part is connected with controller.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The moistureproof dry-type transformer of one described in the utility model, at transformer coil outer setting baking pipe and aspiration channel, the hot blast of baking pipe blowout carries out heated baking to the moisture be attached on coil, aspiration channel siphons away the steam after heating, effectively prevent wet weather iron core, high-voltage coil and low-voltage coil makes moist and cause the generation of insulation resistance phenomenon on the low side, ensure and the operation that transformer safety is stable extended useful life.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited only to these examples, and under the prerequisite for departing from present inventive concept, any improvement of doing all drops within protection scope of the present invention.
As shown in the figure, the moistureproof dry-type transformer of one described in the utility model, comprise iron core, described iron core is respectively equipped with low pressure winding from inside to outside, insulating barrier and high pressure winding 2, described iron core upper and lower side is equipped with grip block 1, described high pressure winding 2 outside is provided with several moistureproof pipes 3, described moistureproof pipe 3 comprises baking pipe 4 and aspiration channel 5, described baking pipe 4 and aspiration channel 5 are equipped with several pores, described grip block 1 top is provided with hair-dryer 7, induced-draught fan 8 and controller 9, described hair-dryer 7 gas outlet is communicated with baking pipe 4 by heater 71, described induced-draught fan 8 is communicated with aspiration channel 4, several described moistureproof pipes 3 are fixed between upper and lower grip block 1, annular array centered by core center line, described high pressure winding 2 outside is provided with humidity sensor 10, and described humidity sensor 10 signal output part is connected with controller 9, at transformer coil outer setting baking pipe and aspiration channel, the hot blast of baking pipe blowout carries out heated baking to the moisture be attached on coil, aspiration channel siphons away the steam after heating, effectively prevent wet weather iron core, high-voltage coil and low-voltage coil makes moist and cause the generation of insulation resistance phenomenon on the low side, ensure and the operation that transformer safety is stable extended useful life.
