Abstract: Jet circulation hot air heating and drying technology is a vacuum drying technology, which uses compressed air jet drive to replace the disturbance of traditional fan to realize convective heat transfer of hot air circulation and heating transformer. This technology overcomes the shortcomings of traditional hot air circulation and pressure drying technology, and improves the technical performance of transformer hot air circulation drying from the physical principle.It has remarkable effect on improving heating efficiency of drying equipment, preventing rust of iron core, improving temperature distribution and ensuring vacuum degree of drying system.

Key words: transformer drying, variable voltage method, aerodynamics, jet cycle, hot air heating
