Abstract
The invention provides a water-resistant transformer. The water-resistant transformer comprises an iron core, a winding, an oil tank and an oil pillow; the winding is wound around the iron core; the iron core and the winding are arranged in the oil tank; the oil pillow is arranged on the oil tank and is connected with the oil tank through a corrugated pipe; the oil pillow is a vertically arranged oil cylinder; a piston is arranged inside the oil cylinder; the piston and the oil cylinder are in airtight fit; a hole covered by a semi-permeable membrane is formed in the middle of the piston; the semi-permeable membrane is a water molecule semi-permeable membrane; and an end cover provided with an air vent is arranged at the top of the oil cylinder. According to the water-resistant transformer provided by the invention, the semi-permeable membrane is used for discharging water molecules, so that the purpose of removing water in the oil tank of the transformer is achieved, and the stability of the transformer is improved.
Description
Technical field
[0001] the present invention relates to the potential device field, especially, is a kind of transformer that effectively dewaters.
Background technology
[0002] transformer is formed parts and is comprised device body (iron core, winding, insulation, lead-in wire), transformer oil, fuel tank and conservator.The transformer conservator is installed on the fuel tank of transformer, also has the pipeline of a usefulness " glass " sealing, is " explosion stack "; When preventing transformer fault exactly, oily temperature increases fast, and volume sharply expands; In the time of can not having held in the conservator; Oil stream will squeeze cullet, goes out from explosion stack, and the protection transformer does not receive big damage.Oil tank of transformer is filled oil, and just oil can not be expired very much in the conservator of transformer.Fuel tank is connected through pipeline with conservator, and when lacking oil in the fuel tank, the oil in the conservator will add in the fuel tank along under the channel flow, makes it to keep full oil condition; Simultaneously, when the transformer load increase, oily temperature increases, and transformer oil expands, and when not containing in the fuel tank, also can be back in the conservator along the pipeline upper reaches.
When transformer was installed on the comparatively moist torrid zone or subtropical climate regional, the moisture content in the inner insulating oil of transformer can increase, thereby reduced the breakdown strength of transformer oil, caused the potential safety hazard of transformer.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of anti-water transformer, this transformer can be removed the oil in the oil tank of transformer.
The technical solution adopted for the present invention to solve the technical problems is:
This anti-water transformer comprises iron core, winding, fuel tank and conservator; Said winding is wound on the iron core; Said iron core and said winding are arranged in the said fuel tank, and said conservator is arranged on the said fuel tank and through a bellows and is connected with said fuel tank, and said conservator is that the said oil cylinder set inside of a vertically disposed oil cylinder has piston; Said piston and said oil cylinder air-tight fit; Said piston middle part has the hole that is covered by pellicle, and said pellicle is the hydrone pellicle, and said oil cylinder top is provided with the end cap that has air vent hole.
As preferably, the quality of said piston is greater than 3% of the transformer gross mass.
As preferably, in the middle of said fuel tank top is high around low shape, said bellows connects and fuel tank top highest point.
As preferably, in the middle of being, said fuel tank bottom hangs down high shape all around, and said bottom lowest part is provided with pellicle.
As preferably, the said pellicle that is arranged at the fuel tank bottom is provided with the ventilation protective cover.
The invention has the advantages that:
The conservator set inside of cylinder type has the piston of pellicle; Because the weight of piston extruding transformer oil; And the moisture in the transformer generally exists with vaporous, and moisture gets into from fuel tank in the conservator, and hydrone is through the pellicle on the piston; Reach the purpose of removing moisture in the oil tank of transformer with this, improve the stability of transformer.
