Heat dissipation protection equipment based on oil-immersed high-frequency transformer

Abstract

The invention discloses heat dissipation protection equipment based on an oil-immersed high-frequency transformer. The equipment comprises a shell; an iron core is arranged in the shell; the top of the iron core is fixedly connected with a heat conduction rod; the top of the heat conduction rod is slidably connected with a mercury pipe; a stop block is connected into the mercury tube in a slidingmanner; the top of the stop block is fixedly connected with a bearing rod; a rotating wheel is arranged in the guide pipe; the right side of the rotating wheel is rotationally connected with a centrifugal wheel through a belt; a baffle is arranged on the right side of the centrifugal wheel; the side face of the baffle is rotationally connected with an extrusion rod; a conductive block is arrangedat bottom of the extrusion rod; a wire is arranged at bottom of conductive block; and a load element is arranged below the wire. According to the heat dissipation protection equipment based on the oil-immersed high-frequency transformer, through cooperative use of the transition box and the heat conduction rod, the effects that protection is generated during heat accumulation of the iron core, andthe iron core is prevented from being damaged due to overheating are achieved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a heat dissipation protection device based on an oil-immersed high-frequency 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. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc., which can be divided according to the purpose For: power transformers and special transformers, special transformers include electric furnace transformers, rectifier transformers, transformers, etc. [0003] For oil-immersed transformers, the heat dissipation of the transformer is to transfer heat to the oil nearby through the iron core and coil, and then the heated oil leaves the transformer, then is cooled by the radiator, and then enters the transformer again, and ci...
