The traditional electromagnetic soft interconnection device of a distribution network uses a mechanical on-load voltage regulating switch, which has some disadvantages such as limited regulating speed, less frequent switching, mechanical wear and it is easy to produce an arc. To overcome these disadvantages, the structure of the switching switch of the electromagnetic soft interconnection device is improved, and a corresponding fast switching method is proposed. The proposed electronic switch structure consists of reverse parallel thyristor switch taps and series multi-coupling inductors, which can be adjusted across multiple levels. It can not only effectively restrain the short circuit current level during tap switching and realize reliable switching, but also reduce the regulation branch, reduce the number of regulations, and shorten the switching time. Finally, this paper builds a Matlab/Simulink simulation model to verify the feasibility of the fast cutting method.
