Among the figure: 1 vacuum interrupter, 2 permanent magnets, 3 mount pads, 4 seesaw buttons, 5 panels, 6 lower connecting terminals, 7 upper connecting terminals, 8 fixed contacts, 9 moving contacts, 10 conduction seesaws, 11 are flexible coupling, 12 conduction seesaw seats, 13,13 ' electrician's iron, 14 limiting buffer seats, 15 button limiting stands.
Embodiment
The present invention is further described with reference to the accompanying drawings.The present invention mainly is comprised of vacuum interrupter (1), permanent magnet (2), mount pad (3) and seesaw button (4).Vacuum interrupter (1) shell adopts glass tube or earthenware to make, and the lower connecting terminal (6) at vacuum interrupter (1) two ends and upper connecting terminal (7) and conduction seesaw (10) all adopt the oxygen-free copper punch forming.Inlay fixed contact (8) in vacuum tube the inner of lower connecting terminal (6), inner weld be flexible coupling (11) of the vacuum tube of upper connecting terminal (7), be flexible coupling (11) the other end with the conduction seesaw (10) weld together, the other end of conduction seesaw (10) is inlayed moving contact (9) in the position of corresponding fixed contact (8), electrician's iron (13) and (13 ') are inlayed respectively in the front, two ends of conduction seesaw (10), electrician's iron can adopt silicon steel to replace but can not adopt carbon steel, to avoid magnetization phenomenon, fixed contact (8) and moving contact (9) adopt chromiumcopper to make; Conduction seesaw seat (12) is equipped with in centre position, the place ahead in vacuum interrupter (1) cavity, conduction seesaw seat (12) is supported on the middle part of conduction seesaw (10), a bonding limiting buffer seat (14) on conduction seesaw (10) welding is flexible coupling the end back tube wall of (11), make opening apart from about 2～3mm of fixed contact (8) and moving contact (9), the material that limiting buffer seat (14) can adopt stainless steel wire etc. to have certain temperature capacity and toughness is made.When the shell of vacuum interrupter (1) adopts glass tube to make, fixedly melting welding is firm with lower connecting terminal (6) first, the conduction seesaw seat (12) that will assemble again, conduction seesaw (10), connect be flexible coupling (11), upper connecting terminal (7) and limiting buffer seat (14) and fix at the glass tube inwall, glass tube is vacuumized the rear evenly rapidly heating in border, glass tube welding position, because the suction function in the pipe, the copper body of softening glass tube and upper connecting terminal (7) is welded together; When making such as the shell employing earthenware of vacuum interrupter (1), the both ends of the surface of earthenware are carried out high temperature metallization process after grinding, refill and prepare the pipe inner part, in the vacuum seal stove, carry out the air-tightness welding with yellow gold.Mount pad (3) adopts the disposable die casting moulding of electrician's bakelite material, there is the button limiting stand (15) of respective protrusions to run into vacuum interrupter (1) and produce mechanical damage to prevent seesaw button (4) in the two side of mount pad (3), the scope of activities of permanent magnet (2) is greater than more than 1 times of conduction seesaw (10) scope of activities, in order to avoid form the movable dead point of conduction seesaw (10).Seesaw button (4) also adopts electrician's bakelite material die casting moulding, and the front disposable die casting moulding of permanent magnet (2) of putting in its inside, back side is pressed in casting.Vacuum interrupter (1) is installed on mount pad (3) base plate first during assembling, can carry out in case of necessity cementing, or admittedly be enclosed on the mount pad (3) with resin material, again seesaw button (4) is installed in the middle of the two side of mount pad (3), covers panel (5) and namely finish assembling.The contour structures of mount pad (3) and panel (5) can be made into wall type or hand-hold type, the structure such as portable according to requirements.
The part that the upper end of seesaw button (4) is projected on panel during combined floodgate is pressed, permanent magnet (2) upper end is near electrician's iron (13 '), both draw close to the centre rapidly under the effect in magnetic field, seesaw button (4) stops mobile under the effect of button limiting stand (15), the upper end of electrician's iron (13 ') band moving conductive seesaw (10) moves forward, the end that the seesaw (10) that conducts electricity under the effect of conduction seesaw seat (12) is inlaid with moving contact (9) moves backward, stops the mobile making process of finishing with fixed contact (8) closure and after applying certain pressure.
The part that the lower end of seesaw button (4) is projected on panel during separating brake is pressed, permanent magnet (2) upper end is away from electrician's iron (13 '), the lower end is near electrician's iron (13) simultaneously, after the distance of its distance less than permanent magnet (2) upper end and electrician's iron (13 '), both draw close to the centre rapidly under the effect in magnetic field, seesaw button (4) stops mobile under the effect of button limiting stand (15), the lower end of electrician's iron (13) band moving conductive seesaw (10) moves forward, pressure between the dynamic/static contact reduces at this moment, contact area reduces, resistance strengthens, current density increases, and produces metallic vapour and form vacuum arc in vacuum interrupter (1).Both are close rapidly under the effect in magnetic field because permanent magnet (2) lower end is further near electrician's iron (13), and the distance of dynamic/static contact is pulled open rapidly and the mistake nought state of electric current, and electric arc moment extinguishes, and dielectric strength is recovered immediately.
