Technical Field

Background

A transformer is a device that changes an alternating voltage using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). In electrical equipment and wireless circuits, the high-voltage power supply is often used for voltage rise and fall, impedance matching, safety isolation and the like. In a generator, an electrical potential can be induced in a coil, whether the coil is moved through a magnetic field or a magnetic field is moved through a stationary coil. In both cases, the value of the magnetic flux is constant, but the amount of the magnetic flux linked with the coil varies, which is the principle of mutual induction. A transformer is a device for transforming voltage, current and impedance by using mutual electromagnetic induction.

In the prior art, in the working process of a transformer, water cooling operation is often required to be carried out on a reactor, but when the transformer is used in a region with large day-night temperature difference, the transformer can work very inefficiently due to the fact that a water cooling device cannot work due to overlarge temperature difference change, excessive or too little use can be caused on cooling liquid, and the working efficiency of the water cooling reactor is influenced.
