Problems solved by technology

[0004] Existing transformer casings generally do not have a structure specially designed to improve heat dissipation efficiency, so the heat dissipation performance is poor, which leads to the fact that when the transformer uses a large power, the heat generated inside cannot be dissipated in time, resulting in excessive temperature , it is very likely to cause irreversible damage to the internal coil, and even an explosion in severe cases, posing a threat to people's lives and property.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a heat dissipation protection casing for a transformer. Background technique [0002] A transformer (Transformer) refers to a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are primary coils, secondary coils and iron cores (magnetic cores). [0003] The main functions of transformers are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc., and can be divided into power transformers and special transformers according to their uses. [0004] Existing transformer casings generally do not have a structure specially designed to improve heat dissipation efficiency, so the heat dissipation performance is poor, which leads to the fact that when the transformer uses a large power, the heat generated inside cannot be dissipated in time, resulti...
