Background

The mutual inductor is also called instrument transformer, and is a general name of current mutual inductor and voltage mutual inductor. The high voltage can be changed into low voltage, and the large current can be changed into small current for measuring or protecting the system. Its function is mainly to convert high voltage or large current into standard low voltage (100V) or standard small current (5A or 1A, both referring to rated value) in proportion so as to realize standardization and miniaturization of measuring instrument, protection equipment and automatic control equipment. Meanwhile, the mutual inductor can be used for isolating a high-voltage system so as to ensure the safety of people and equipment.

The existing mutual inductor adopts epoxy resin to be in direct contact with air, has no shielding protective layer outside, directly interferes with the operation of the mutual inductor once the outside meets a strong magnetic field, destroys the safety and the stability of the mutual inductor, and is provided with a copper sheet shielding layer outside the mutual inductor, so that the problems can be solved.

The copper sheet of mutual-inductor has 2 effects: 1. in the pair: electric field and magnetic field of the uniform coil; 2. and (3) outward: shielding the electric field and the magnetic field of the coil; therefore, the large-spot mutual inductor can be wrapped with a layer of copper sheet.
