Document Type and Number:
WIPO Patent Application WO/2018/070023
Kind Code:
A1
Abstract:
An on-load tap switching device according to an aspect of the present invention has a changeover switch and an insulating mediator. The changeover switch includes a semiconductor switch, and shifts the transformation ratio by switching the connection relationship with respect to a tap selector connected to a transformer. The insulating mediator electrically insulates the semiconductor switch from a control circuit located outside a transformer storage part that stores the transformer, and mediates a signal from the control circuit to a gate terminal of the semiconductor switch.
