Description

Technical Field

[0001] The utility model relates to the technical field of dry-type transformers, in particular to a dry-type transformer provided with a cooling and heat dissipation mechanism. Background Art

[0002] A dry-type transformer is a transformer that does not use liquid coolant, and usually uses air or other gases as insulation and cooling media; the rated capacity and performance parameters of dry-type transformers are similar to those of liquid-cooled transformers and can be described by various electrical parameters, such as rated voltage, rated capacity, short-circuit impedance, etc.

[0003] A Chinese patent with authorization announcement number CN209591717U discloses an easy-to-dissipate heat dry-type transformer, comprising a shell and a coil body arranged in the shell, a support frame is fixedly connected to the bottom of the shell, the coil body is installed on the support frame, an air inlet is opened at the top of the shell, a heat dissipation fan is installed in the air inlet, and the output end of the heat dissipation fan is arranged toward the coil body; by arranging the air inlet, the heat dissipation fan, the ventilation slot, the ventilation hole, the filter, the bearing, the rotating shaft, the brush and the impeller, the heat dissipation fan is started to input the external cold air into the shell, the coil body in the shell is cooled, the hot air in the shell enters the ventilation slot through the ventilation hole, and the gas is output from the ventilation slot. A driving force is applied to the impeller, and the impeller drives the rotating shaft to rotate in the bearing after being subjected to the force, and the rotating shaft drives the bristles of the brush to rub the filter, and the dust stuck on the mesh diameter of the filter is brushed off, which does not affect the ventilation effect of the filter, thereby improving the normal heat dissipation effect of the transformer.

[0004] The shortcomings of the above-mentioned prior art solution are: the above-mentioned solution applies a driving force to the impeller when the gas is output through the ventilation groove. After the impeller is subjected to the force, it drives the rotating shaft to rotate in the bearing. When the rotating shaft rotates, the bristles of the brush are driven to rub the filter screen, and the dust stuck on the mesh diameter of the filter screen is brushed off, thereby improving the normal heat dissipation effect of the transformer. However, the heat dissipation effect is improved by simply cleaning the dust, which cannot meet the heat dissipation requirements of the dry-type transformer. The dry-type transformer is large in size and needs to be heat-dissipated from multiple directions. Here, we provide a dry-type transformer with a cooling and heat dissipation mechanism.
