Abstract

The invention belongs to the technical field of mutual inductors, and particularly relates to an environment-friendly intelligent mutual inductor and a mutual inductor compensation method. The intelligent mutual inductor comprises a mutual inductor, an outer shell and an inner shell, wherein an insulating material is arranged between the outer shell and the inner shell; the mutual inductor is arranged in the inner shell; the mutual inductor comprises a mutual inductor body, a delay compensation device and a saturation calculation device; the delay compensation device and the saturation calculation device are in signal connection with the mutual inductor body; the delay compensation device is used for performing delay compensation on the mutual inductor; the saturation calculation device isused for calculating the saturation degree of the mutual inductor and controlling the mutual inductor to operate. The intelligent mutual inductor has the advantages of environmental protection, energy conservation, easy use and installation, good mutual induction performance and accurate time delay compensation.

Description

technical field [0001] The invention belongs to the technical field of transformers, and in particular relates to an environment-friendly intelligent transformer and a compensation method for the transformer. Background technique [0002] Transformer, also known as instrument transformer, is a general term for current transformer and voltage transformer. It can change high voltage into low voltage and high current into small current for measurement or protection system. Its function is mainly to convert high voltage or high current into standard low voltage (100V) or standard small current (5A or 1A, both refer to rated value) in proportion, so as to realize the standardization and miniaturization of measuring instruments, protection equipment and automatic control equipment. change. At the same time, the transformer can also be used to isolate the high-voltage system to ensure the safety of people and equipment. [0003] In order to transmit electric energy, the power sy...
