The invention discloses a transformer air pressure regulating device suitable for high temperature environment, which comprises a valve body, a hollow valve cavity is arranged inside the valve body, a supporting spring is arranged inside the valve cavity, and a valve body connected to the The membrane disk at the end of the support spring; the valve body is also provided with an air inlet leading to the bottom end of the valve cavity through the outside of the valve body, and leading to the bottom end of the valve cavity through the outside of the valve body. The gas outlet at the side end of the valve cavity; the transformer air pressure regulating device suitable for high temperature environments also includes a temperature regulating mechanism; adopting the above technical scheme, it can be used during the working process of the transformer according to the temperature of the working environment where the transformer is located. , automatically adjust the working threshold of the pressure relief valve to ensure that the transformer oil is fully vaporized when the transformer air pressure adjustment device is opened, so as to avoid the transformer oil that is not fully vaporized when the pressure relief valve is opened due to the high temperature of the working environment where the transformer is located Problems with discharge to the outside of the transformer.
Description
technical field [0001] The invention relates to the field of power equipment, in particular to a transformer air pressure regulating device suitable for high-temperature environments. Background technique [0002] During use, the transformer is often filled with transformer oil for insulation, heat dissipation, and arc suppression. When an accident occurs in the transformer due to the external environment or internal component failure, the transformer oil inside the transformer will be heated and vaporized, which will lead to an increase in the internal pressure of the transformer. In order to avoid the explosion accident caused by the excessive internal pressure of the transformer during the accident, the transformer in the related art is often provided with a protective device for internal gas release, so as to release the high-pressure gas inside the transformer in time when the internal pressure of the transformer increases, so as to To adjust the internal air pressure ...
