Description

Pressure release device for transformer Technical Field The utility model relates to the technical field of pressure release devices, in particular to a pressure release device for a transformer. Background In the running process of the transformer, the oil temperature in the oil tank can be rapidly increased due to internal faults, a large amount of gas is generated by oil decomposition, so that the internal pressure of the transformer is rapidly increased, and if the pressure can not be timely released, serious accidents such as rupture, explosion and the like of the transformer tank body can be caused, so that a pressure release device for the transformer is needed; The chinese patent provides a pressure release device for oil-immersed transformer, publication No. CN220474417U, which comprises a housing, shell left end alternates fixedly connected with collection subassembly, shell lower extreme fixedly connected with inferior valve, inferior valve lower extreme fixedly connected with screwed pipe, inferior valve surface alternates movable mounting has control assembly, the equal fixedly connected with connecting plate of shell left side internal face lower part and right internal face lower part, shell internal face upper portion fixedly connected with roof, roof upper end is opened there is a number of through-hole of a plurality of upper and lower break-through, roof lower extreme fixedly connected with release subassembly, shell upper end fixedly connected with upper junction housing. The device realizes release of pressure through setting up release subassembly, and is simple convenient, and the effectual stability that improves the device to improve the pressure release effect, but the device when using, transformer trouble leads to the oil temperature to rise sharply, and the oil decomposition produces a large amount of gases, and the gas can constantly gather and make the inside pressure of transformer rise rapidly, and the gas discharge leads to the fact the destruction to release easily. Disclosure of utility model The utility model mainly aims to provide a pressure release device for a transformer, which can effectively solve the technical problems that in the background technology, gas continuously gathers to cause the pressure in the transformer to rise rapidly and gas is discharged to easily damage the release device. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a pressure release device for transformer, includes the oil tank, the bottom fixed mounting of oil tank has two support frames, the top fixed mounting of oil tank has two connecting plates, two the close face fixed mounting of connecting plate has the spread box, the bottom fixed mounting of spread box has the intake pipe, intake pipe and oil tank intercommunication, one side rotation of spread box inner wall is connected with the axis of rotation, the outer wall fixed mounting of axis of rotation has the impeller.
