Abstract

Disclosed are a magnetic induction current transfer module and current transfer method thereof. The magnetic induction current transfer module includes inductors and access ends, the inductors include a primary side inductor (1) and a secondary side inductor (2), the access ends include a primary side access end (3) and a secondary side access end (4), two ends of the primary side inductor (1) realize connection with an external circuit through the primary side access end (3), and two ends of the secondary side inductor (2) realize connection with the external circuit through the secondary side access end (4); and the primary side inductor (1) and the secondary side inductor (2) are coupled through a magnetic field and are electrically insulated from each other.

Description

technical field [0001] The invention relates to a magnetic induction current transfer module and a current transfer method thereof, in particular to an electrical device which utilizes magnetic field induction to realize current generation or transfer. Background technique [0002] The DC circuit breaker is the guarantee for the safe operation of the DC power supply system. Because there is no natural zero-crossing point in the DC current, the direct breaking method will be greatly restricted. The effective way to solve this problem is to create a current zero-crossing point based on current transfer. New breaking method. The way of current transfer can be divided into two ways: natural current transfer and forced current transfer. Among them, the effect of the natural current transfer method is affected by various factors such as component parameters, component coordination, and working conditions, and there are many limitations in engineering practical applications. In c...

Problems solved by technology

[0005] The above-mentioned documents all use the magnetic induction current transfer method. However, the above-mentioned patent documents only involve the current transfer circuit and the transfer method, which are relatively theoretical, but lack of discussion on the realization of the magnetic induction current transfer module itself, which limits the better application of this transfer method. one of the reasons

On the other hand, although there are many types of transformers that have appeared on the market, their working current is small and the current-to-volume ratio is low, so it is difficult to meet the current requirements of thousands of amperes in large-capacity power systems.
