Abstract

The invention discloses an insulated wire structure medical isolation transformer comprising a transformer core, a primary winding, a secondary winding and an interlayer insulating layer. The primary winding is wound on the outer side of the transformer core. The interlayer insulating layer is arranged on the outer side of the primary winding. The secondary winding is wound on the outer side of the interlayer insulating layer. The outer side of the secondary winding is covered by an external insulating layer. The structural design is novel and the parasitic capacity between the primary and secondary windings can be completely avoided. Besides, the interlayer insulating layer arranged between the transformer core and the primary winding can reduce the temperature rise of the transformer winding; in addition, the temperature rise of the primary winding is reduced after the closed insulation structure is eliminated so that the transformer efficiency is enhanced and the overall size of the product is reduced.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a medical isolation transformer with an insulated wire structure. 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 use, it can be divided into: power transformers and special transformers (electric furnace transformers, rectifier transformers, power frequency test transformers, voltage regulators, mining transformers, audio transformers, intermediate frequency transformers, high frequency transformers, impact transformers, instrument transformers, electronic transformers , reactors, transformers, etc.). [0003] For the currently used toro...
