Problems solved by technology
[0003] At present, the transformers widely used are oil-immersed transformers. However, during the use of oil-immersed transformers, when the oil volume expands due to the high temperature of the shell itself, the internal pressure will increase. Under the action of pressure, the oil will flow from The connection between the gasket and the box cover escapes, causing oil leakage and affecting the normal use of the transformer

The invention discloses an oil-leakage-proof transformer, which comprises a housing, the upper side wall of the housing is rotatably connected with a cover plate, the lower side wall of the housing is provided with a base, and a base is provided between the base and the housing. There is a connecting mechanism, a liquid storage tube is provided on the outside of the housing, a slide plate slides inside the liquid storage tube, a connecting rod is fixedly connected to the upper side wall of the slide plate, and the liquid storage tube is filled with Expansion liquid, a heat conduction rod is fixed between the liquid storage pipe and the outer wall of the housing, an overflow prevention pipe is inserted on the upper side wall of the housing, a piston slides inside the overflow prevention pipe, and the end of the connecting rod A lifting rod is fixedly connected between the upper side wall and the upper side wall of the piston. The present invention realizes the extraction of oil through the movement of the piston when the temperature of the transformer is too high, lowers the height of the oil level, avoids the overflow of the oil, and realizes the flow of the oil by driving the swing of the swing blade to promote the heat dissipation of the oil, and further It avoids the overheating expansion of the oil and ensures the normal use of the transformer.
Description
technical field [0001] The invention relates to the technical field of transformers, in particular to an oil leakage prevention transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. [0003] At present, the transformers widely used are oil-immersed transformers. However, during the use of oil-immersed transformers, when the oil volume expands due to the high temperature of the shell itself, the internal pressure will increase. Under the action of pressure, the oil will flow from The joint between the gasket and the box cover escapes, causing oil leakage and affecting the normal use of the transformer. Contents of the invention [0004] The purpose of the present invention is to solve the problems in the background technology, and propose an oil leakage-proof transformer. [0005] In order to achieve the above object, ...
