Embodiment Construction

[0018] The present invention will be further described in detail through specific embodiments below in conjunction with the accompanying drawings.

[0019] As shown in the figure, the disk-type rotary magnetic vertical blowing vacuum interrupter includes a contact cup 1 with several inclined grooves on the outer wall. The contact piece 2 is fixedly connected to the cup mouth of the contact cup 1. The contact cup 1 The end away from the contact piece 2 is fixedly connected with a conductive rod 3, and a support mechanism is provided inside the contact cup 1. The top of the support mechanism is in contact with the contact piece 2, and an iron core 4 is set on the outside of the support mechanism, and the iron core 4 is along the circumference A plurality of slots 5 are evenly opened, and the coil windings 6 are embedded in the slots 5, and the coil windings 6 are radially distributed to form a disc structure. Coil winding 6 is manufactured by punching copper plate and then weldi...

Abstract

The invention discloses a disc type gyromagnetic longitudinal blowing vacuum arc-extinguishing chamber. A contact cup is included, the outer wall of the contact cup is provided with an inclined groove; a contact blade is fixedly connected to a cup opening of the contact cup; one end, far away from the contact blade, of the contact cup is fixedly connected with a conducting rod; a supporting mechanism is arranged in the contact cup, the two ends of the supporting mechanism make contact with the contact piece and the inner wall of the contact cup respectively, the supporting mechanism is sleevedwith an iron core, the iron core is evenly provided with a plurality of open grooves in the circumferential direction, coil windings are arranged in the open grooves, and the coil windings are distributed in a radial shape in the radial direction to form a disc type structure. The contact blade is stable in structure, high in arc temperature drop speed, high in insulation performance and high inbreaking capacity.

Description

technical field [0001] The invention relates to the field of vacuum circuit breakers, in particular to a disk type gyromagnetic vertical blowing vacuum interrupter. Background technique [0002] Vacuum circuit breaker is named for its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no maintenance for arc extinguishing. The application is more popular. Vacuum circuit breaker is an indoor power distribution device in 3-10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants, and substations, especially suitable for oil-free, less In places where maintenance and frequent operations are used, circuit breakers can be configured in central cabinets, double-layer cabinets, and fixed cabinets to control and protect high-voltage elec...
