Abstract
The utility model discloses a longitudinal magnetic contact of a bounce-proofing vacuum arc extinguish chamber, comprising a coil and a contact blade, wherein chutes are evenly distributed at the circumference wall of the coil; the coil is internally and fixedly provided with a support plate; notches corresponding to the chutes are evenly distributed on the contact blade; the magnetic contact is characterized in that an upper port of the coil is fixedly connected with a tray made of oxygen-free copper; the contact blade is fixed on the upper surface of the tray; notches corresponding to the chutes are evenly distributed on the tray; the notches in the tray and the notches in the contact blade are respectively coincided; and the upper surface of the support plate is fixedly connected with the tray. The magnetic contact has the following advantages: the tray made of the oxygen-free copper is arranged between the coil and the contact blade, therefore, in the high-speed switching process of the vacuum switch, springing ability generated by the rigid collision among the contacts can be absorbed, thus greatly shortening the springing time, reducing the springing amplitude and fully meeting mechanical parameter requirements of a vacuum circuit breaker and springing requirements on the vacuum arc extinguish chamber.
Description
Technical field
The utility model is particularly related to a kind of vertical magnetic contact of vacuum interrupter of anti-spring.
Background technology
The vertical magnetic contact of traditional vacuum interrupter generally is that contact and coil directly weld, and directly is welded with supporting disk below the contact.In vacuum switch high speed making process, owing to the rigidity collision produces spring, bounce time is long between two contacts, and the spring amplitude is big, can't satisfy the mechanical parameter requirement of vacuum circuit-breaker.Vertical magnetic contact after the improvement is to weld supporting disk at contact below by pad, reduces to some extent although this structure is compared spring with traditional structure, but still can not satisfy the requirements at the higher level of high-pressure vacuum breaker to the vacuum interrupter spring.
The utility model content
The technical problems to be solved in the utility model provides a kind of spring that can absorb contact collision and produce, and bounce time is short, and the spring amplitude is little, satisfies the vertical magnetic contact of vacuum interrupter of the anti-spring that the mechanical parameter of vacuum circuit-breaker requires.
Technical solution of the present utility model is: it comprises coil and contact blade, on the circle wall of coil, be evenly equipped with skewed slot, be installed with supporting disk in coil, on contact blade, be evenly equipped with the notch corresponding with skewed slot, its special character is: be connected with the pallet that oxygen-free copper is made in that coil is suitable for reading, described contact blade is fixed on tray upper surface, on pallet, be evenly equipped with the notch corresponding with skewed slot, notch on the pallet overlaps respectively with notch on the contact blade, and described supporting disk upper surface and pallet are affixed.
The vacuum interrupter of above-mentioned anti-spring is indulged the magnetic contact, and its special character is: be provided with groove at tray upper surface, described contact blade bottom embeds in the groove.
The utility model has the advantages that: owing between coil and contact blade, be provided with the pallet that oxygen-free copper is made, in vacuum switch high speed making process, can absorb the spring that produces because of the collision of the rigidity between contact, thereby shortened bounce time greatly, reduced the spring amplitude, the mechanical parameter that has satisfied vacuum circuit-breaker fully requires and to the requirement of vacuum interrupter spring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
