Problems solved by technology

[0003] The traditional contactor with auxiliary contact monitoring function uses a magnetic circuit system to drive a transmission part to realize the switching function of the main contact and the auxiliary contact, so the load of the magnetic circuit system is heavy, and the main contact and the auxiliary contact The assigned contact pressure is less, which eventually leads to insufficient contact load capacity or less life parameters, so a new contactor is proposed

Abstract

The invention discloses a contactor of a dual-magnetic-circuit system. The contactor comprises a main contact magnetic circuit system and an auxiliary contact magnetic circuit system. The main contactmagnetic circuit system is composed of a contact system a and an electromagnetic system a, a contact sealing cavity of the contact system a is subjected to vacuum pumping and air inflation, the electromagnetic system a and the contact system a are cooperatively installed, and the electromagnetic system a can be used for driving the contact system a; the auxiliary contact magnetic circuit system is installed at the bottom of the main contact magnetic circuit system and comprises a contact system b and an electromagnetic system b, the contact system b and the electromagnetic system b are cooperatively installed, and the electromagnetic system b can drive the contact system b. According to the contactor of the dual-magnetic-circuit system, through separation design of the main contact magnetic circuit system and the auxiliary contact magnetic circuit system, the load of the dual-magnetic-circuit system is reduced, the contact pressure of a main contact and an auxiliary contact is increased, the service life of the contactor is prolonged, and the reliability of the contactor is improved.

Description

technical field [0001] The invention belongs to the technical field of contactors, and in particular relates to a contactor of a double magnetic circuit system. Background technique [0002] With the development of science and technology, aerospace devices have developed in the direction of multi-function, multi-purpose, intelligence and integration. Contactors with auxiliary contact monitoring function, as an important device used in the aerospace field, are widely used to frequently connect and disconnect AC and DC large-capacity control circuits, providing a reliable guarantee for the switching of the power circuit of the whole machine. [0003] The traditional contactor with auxiliary contact monitoring function uses a magnetic circuit system to drive a transmission part to realize the switching function of the main contact and the auxiliary contact, so the load of the magnetic circuit system is heavy, and the main contact and the auxiliary contact The assigned contact ...
