Description

Mutual inductor

Technical Field

The utility model relates to the technical field of mutual inductors, in particular to a mutual inductor.

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.

Usually, the primary winding and the secondary winding on the mutual inductor body are directly compressed through the screw when being connected with the wire, and the wire is easily wound on the screw along with the rotation of the screw in the rotation process of the screw in the connection mode, and particularly when the wire is thin, the wire is easily twisted off under the action of the external thread on the screw to influence the connection effect of the mutual inductor and the wire.

A new solution is therefore proposed to solve this problem.
