Problems solved by technology

In order to ensure the contact between the moving contact and the static contact, the coil needs to be energized all the time, and the relay is easily disturbed by the external magnetic field, causing the relay to malfunction and accidentally separating the moving and static contacts.
The contact between the moving contact and the static contact of the electromagnetic relay will generate repulsion. If the upward thrust of the push rod is insufficient, the phenomenon of poor contact between the moving and static contacts will easily occur. In order to ensure that the moving contact can reliably contact the static contact, it is necessary to Increase the number of turns of the coil, increase the size of the relay, and increase the production cost of the relay

Abstract

The invention discloses a motor type high-voltage direct-current relay. The motor type high-voltage direct-current relay comprises a casing, wherein a movable contact assembly, a stationary contact assembly and a drive assembly are arranged in the casing; the movable contact assembly comprises a movable contact spring which is fixed with the upper end of a push rod, and a rack is fixed at the lower end of the push rod; the drive assembly comprises a motor, an output shaft of the motor is in linkage with the rack through a worm, and the axis of the worm is parallel to the axis of the push rod.

Description

technical field [0001] The invention relates to a high-voltage direct-current relay, in particular to a motor-type high-voltage direct-current relay which provides power for the contact or breaking of dynamic and static contacts through a motor. Background technique [0002] The current relays are mostly electromagnetic relays, including coils, magnetic tubes, moving iron cores, push rods fixed in the moving iron cores, moving reeds fixed on the top of the push rods, moving contacts fixed on the moving reeds and Static contacts, etc. When working, the coil is energized to cause electromagnetic induction effect, so that the moving iron core moves up and down in the magnetic tube, so that the moving reed drives the moving contact to contact the static contact, or the coil is powered off to make the moving spring The piece is returned to its original position by the force of the spring, so that the movable contact is separated from the static contact. In order to ensure the co...
