Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil tanks, in particular to a transformer oil tank structure. Background Art

[0002] The oil tank is the outer shell of the transformer, which contains the iron core and windings and is filled with transformer oil, so that the iron core and windings are immersed in the oil. The transformer oil plays an insulating and heat dissipating role. There is an oil pillow connected to the surface of the oil tank through a pipe. When there is a lack of oil in the oil tank, the oil in the oil pillow will flow down the pipe and replenish the oil tank to keep it full of oil. At the same time, when the transformer load increases, the oil temperature rises, the transformer oil expands, and the oil tank can no longer hold it, it will also flow up the pipe and flow back to the oil pillow.

[0003] However, the explosion-proof valve on the traditional oil pillow generally adopts a single spring. After a long time, the opening pressure of the explosion-proof valve may be inaccurate. Due to the inaccurate opening pressure of the explosion-proof valve, excessive or insufficient pressure relief may occur, which will directly affect the normal operation of the transformer, which will directly reduce the safety of the transformer.

[0004] Therefore, it is necessary to provide a transformer oil tank structure to solve the above technical problems. Utility Model Content

[0014] The utility model provides a transformer oil tank structure, which is provided with an explosion-proof block. When the device is used, when the internal pressure of the oil pillow is too large, gas will be ejected through the pressure relief port. At this time, the gas will lift up the floating block.
