Problems solved by technology

[0003] When using the pressure release device, the gas inside the transformer is discharged through the pressure release valve. During the discharge process of the pressure release valve, the oil inside the transformer will be ejected from the outlet of the pressure release valve under the action of the gas. The ejected oil A large area of ​​adhesion will spread to the entire surface of the transformer, resulting in transformer oil everywhere in the transformer, which will corrode and pollute the transformer for a long time, and the spring inside the pressure releaser will rust due to the impact of the transformer oil, resulting in The pressure release device is not sensitive when releasing the pressure, which affects the pressure discharge inside the transformer and reduces the use effect of the pressure release device

Abstract

The invention discloses a pressure release device for an oil-immersed transformer. The pressure release device structurally comprises a mounting base, a hinge, a release cylinder, a high-pressure air bag and a protection device. When the pressure release device is used, connecting plates are pushed out forwards through matching between guide plates and connecting pieces, so that a sealing cushion can be connected to the release cylinder under the effect of soft arc pieces; and a connecting arc block is supported under the matching effect of fork clamps and top expansion pieces, so that the connecting arc block can be effectively matched with the sealing cushion to protect the outer wall of the release cylinder, accumulated oil injected from the interior of a transformer is prevented from adhering and spreading to the whole surface of the transformer, and the sensitivity of a pressure releaser during pressure release and the use effect of the pressure releaser are improved.

Description

technical field [0001] The invention relates to the field of transformers, in particular to a pressure release device for oil-immersed transformers. Background technique [0002] The transformer is one of the important devices in the substation and plays an important role in the power system. For the oil-immersed transformer, when a short-circuit fault occurs inside the transformer, a large amount of gas will be generated, and it will be processed through the pressure relief valve. The oil-separating element blocks the transformer oil. When using the pressure relief valve, it needs to be improved: [0003] When using the pressure release device, the gas inside the transformer is discharged through the pressure release valve. During the discharge process of the pressure release valve, the oil inside the transformer will be ejected from the outlet of the pressure release valve under the action of the gas. The ejected oil A large area of ​​adhesion will spread to the entire su...
