Sound insulation type oil immersed transformer

Abstract

The invention discloses a sound insulation type oil immersed transformer which comprises a base, wherein a device box is arranged at the top of the base, an oil tank is arranged at the top of the device box, silencing boxes are arranged on the two sides of the oil tank, a mounting plate is arranged in the oil tank, an iron core is arranged at the top of the mounting plate, a winding is arranged on the outer side of the iron core, and the bottom of the oil conservator is communicated with an oil pipe penetrating into the oil tank. By means of the linkage mechanism, multiple sets of silencing cotton can move up and down back and forth in a staggered mode, due to the fact that the multiple sets of apertures are formed in the multiple sets of silencing cotton, when the silencing cotton moves up and down, the multiple sets of apertures are continuously staggered, and when noise is spread into the silencing cotton, sound waves can be intricate when penetrating through the apertures, due to viscous resistance of air and continuous vibration friction between the air and the hole wall, most sound energy can be converted into heat energy to be absorbed, and the silencing effect is better.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a sound-insulating oil-immersed transformer. Background technique [0002] Oil-immersed transformers use oil as the main insulation method of the transformer and rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation, etc. The main components of the transformer include iron core, winding , Fuel tank, oil pillow, respirator, explosion-proof pipe (pressure relief valve), radiator, insulating bushing, tap changer, gas relay, thermometer, oil purifier, etc. [0003] During the operation of the transformer, although the transformer oil provides a certain resistance and brings some noise reduction, the noise caused by the vibration of the iron core and windings during high-load operation is still difficult to eliminate, resulting in There is also the problem of high noise in the process...
