Document Type and Number:
WIPO Patent Application WO/2021/254004
Kind Code:
A1
Abstract:
Disclosed in the present application is a phase-change switch, comprising: an insulating housing, a power wire inlet end, a power wire outlet end, at least one movable contact, and at least two stationary contacts. The power wire inlet end comprises a first power wire inlet end and a second power wire inlet end, and the power wire outlet end comprises a first power wire outlet end and a second power wire outlet end; the second power wire inlet end is electrically connected to the second power wire outlet end by means of the stationary contacts and the movable contact, the first power wire inlet end is directly and electrically connected to the first power wire outlet end, and the first power wire outlet end and the second power wire outlet end are insulated from each other. According to the phase-change switch of the present application, one power wire outlet end is directly connected to one power wire inlet end, so that only part of current is converted during phase change, and inter-phase current balance is facilitated.
