Title:
DRIVE STRUCTURE FOR HIGH-VOLTAGE DIRECT-CURRENT RELAY
Document Type and Number:
WIPO Patent Application WO/2021/004104
Kind Code:
A1
Abstract:
Provided is a drive structure for a high-voltage direct-current relay, the drive structure comprising: a retaining frame, a stopper piece, a movable spring piece, and an elastic member. The retaining frame comprises two retaining side arms, a support plate, and a drive rod. The two retaining side arms are disposed at two sides of the support plate, and the drive rod is connected to a bottom portion of the support plate. The stopper piece has one end connected to a terminal end of one of the retaining side arms, and the other end connected to a terminal end of the other retaining side arm. The elastic member has one end pressing against the support plate and the other end pressing against the movable spring piece, the movable spring piece presses against the stopper piece, and the stopper piece is provided with an arc isolation portion. The drive structure for a high-voltage direct-current relay has an bottom-up assembly manner, in which the elastic member, the movable spring piece, and the stopper piece are stacked sequentially, and the stopper piece is connected to and retained by the two retaining side arms, thereby realizing a simple and fast assembly process, and increasing assembly efficiency of high-voltage direct-current relays. In addition, the arc isolation portion has an effect of isolating arcs, thereby improving a service life of high-voltage direct-current relays despite reverse arcs.
