Dust-proof dry-type low-temperature transformer

Abstract

The invention provides a dust-proof dry-type low-temperature transformer. The dust-proof dry-type low-temperature transformer comprises a transformer box, a transformer body and a dust-proof heat dissipation assembly, wherein the dust-proof heat dissipation assembly comprises a blower, a dust-proof assembly, a support and a fixing plate, the dust-proof assembly and the support are arranged on thefixing plate, the dust-proof assembly is arranged on the upper portion of the support, and the blower is arranged on the support and the dust-proof assembly. Air vents are formed in the bottoms of boxwalls, air outlets are formed in the side walls of a box cover respectively, and an insulating layer and a sound absorption layer are arranged on the inner side of the transformer box. By arranging the top blowing type blower on an upper fastening piece of a transformer core, forming the louvered air vents in the bottoms of the box walls, and forming the rectangular air outlets in the side wallsaround the box cover, the heat dissipation effect of the transformer is enhanced, and temperature rise of the transformer can be reduced to the greatest extent; due to the insulating layer and the sound absorption layer on the side wall in the transformer box, the transformer has the effects of absorbing sound and reducing noise.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a dust-proof dry-type low-temperature transformer. Background technique [0002] Dry-type low-temperature transformers, simply put, refer to transformers whose iron core and windings are not immersed in insulating oil. Cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When natural air cooling, the transformer can run continuously at the rated capacity for a long time; when forced air cooling, the output capacity of the transformer can be increased by 50%, which is suitable for intermittent overload operation, or emergency accident overload operation; due to load loss and impedance during overload The voltage increases greatly, and it is in a non-economic operation state, so it should not be operated continuously for a long time. [0003] With the continuous expansion of the application technology field, the application of transformers i...
