technical field

The utility model relates to the technical field of electric power, in particular to a fireproof and heat dissipation transformer.

Background technique

The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturated transformer), etc.

Transformers can be divided into distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. according to their uses.

There are many types of existing transformers. Commonly used output high-voltage small transformers are generally composed of iron cores, coils, and skeletons. Such a structure will cause large losses and heat during work, which will easily cause the transformer coil to burn out. At the same time, when the coil When working under high load current for a long time, it is easy to short-circuit the coil wires, which is very easy to cause fire accidents and cause great loss of property.
