Description

technical field [0001] The invention belongs to the field of electric power supply, and in particular relates to a three-phase dry-type transformer. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it 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. [0003] Three-phase dry-type transformers are widely used in electronic computers, precision machine tools, computer tomography (CT), precision instruments, experiments, etc. AC r...
