Abstract

The invention discloses a low-power-consumption high-voltage direct-current contactor. The contactor comprises a ceramic shell, a magnetic pole plate, two static contacts, a movable contact piece, a push rod, a movable iron core and a reset spring, a first mounting groove is concavely formed in the lower side surface of the magnetic pole plate, a second mounting groove is formed in the movable iron core, and the push rod movably penetrates through the second mounting groove and the first mounting groove; the reset spring is provided with a first reset spring arranged outside the push rod in a sleeving mode and a second reset spring arranged outside the first reset spring in a clearance sleeving mode, the first reset spring is further in slight tight fit with the push rod, and the upper end and the lower end of the first reset spring elastically abut against the top wall of the first mounting groove and the bottom wall of the second mounting groove correspondingly; and the lower end of the second reset spring is further restrained in the bottom of the second installation groove, and the upper end of the second reset spring is further movably arranged in the first installation groove. According to the high-voltage direct-current contactor, the power consumption and the temperature rise of the coil are reduced, the stability, the safety and the short-circuit resistance of the contactor are improved, and the development requirements of contactor products are met.

Description

technical field [0001] The invention relates to the technical field of DC contactors, and specifically provides a low-power high-voltage DC contactor capable of reducing coil power consumption and temperature rise. Background technique [0002] In the new energy market, customers are paying more and more attention to the power and temperature rise of the contactor magnetic circuit system, and judging from the current industry development prospects, the magnetic circuit system with low power and small temperature rise is the future development trend. [0003] The power consumption of the contactor magnetic circuit system is reflected in the energy consumed by overcoming the gravity of the moving iron core and the reaction force of the return spring. In the existing contactor structure, usually only one return spring is configured, so when the static contact point and the moving contact piece are closed, the coil needs to provide a large suction force, so that the moving iron ...
