The portable single-phase air bypass switch of the present invention, its principle of work and working process summary are as follows:
The portable single-phase air bypass switch of the present invention, in use, first carry out a point lock energy storage, the upwardly button 14 of the lower end of main shaft, the push rod 33 upwards translational motion of main shaft bottom, drive spring top block 8, combined floodgate energy-stored spring 9, dynamic contact 6, copper row 13, union lever 34, sleeve pipe 12, piston rod 35, piston 11 and point lock energy-stored spring 10 upwards translational motion, make score lock energy-stored spring 10 gradually by compressed energy-storage, when energy storage is abundant, dynamic contact 6 is in combined floodgate state with static contact 5, jack 22 on the push rod 33 of main shaft bottom just intermediate bars with the T-shaped pin 19 of brake-dividing locking assembly be directed at, T-shaped pin 19 moves towards the center of main sleeve 1 under the effect of compression spring 20, make in the jack 22 that the intermediate bars of T-shaped pin 19 is inserted on push rod, lock spindle is fixed on a point state for lock energy storage, then the safe bearing pin 23 on brake-dividing locking assembly is plugged, the mount pad 17 of brake-dividing locking assembly is locked with draw ring 18, prevent mishandle from T-shaped pin is extracted. after completing point lock energy storage, the view of portable single-phase air bypass switch is as shown in Figure 4. then the handle 39 of copper row 13 is pulled downwards, drive dynamic contact 6 and sleeve pipe 12 translational motion downwards, make dynamic contact 6 and static contact 5 separately, combined floodgate energy-stored spring 9 is by compressed energy-storage, when combined floodgate energy-stored spring 9 energy storage is abundant, the intermediate bars of the T-shaped pin 19 that the jack 22 on copper row 13 just locks assembly with combined floodgate is directed at, T-shaped pin 19 moves towards the center of main sleeve 1 under the effect of compression spring 20, the intermediate bars of T-shaped pin 19 is made to be inserted in the jack 22 on copper row 13, copper is arranged 13 and is locked in a point state for lock energy storage, then the safe bearing pin 23 closed a floodgate on locking assembly is plugged, the mount pad 17 of combined floodgate locking assembly is locked with draw ring 18, prevent mishandle from T-shaped pin 19 is extracted.After completing point lock energy storage, the view of portable single-phase air bypass switch is as shown in Figure 5. then bypass connection terminal 16 is connected with by-pass line or grounding wire, then operator rise to the lower section of Awaiting Overhaul circuit by holder device, the connecting joint 26 of rotary connecting joint assembly, because connecting joint 26 and trim ring 29 thread fit, so in the process of rotary connecting joint 26, connecting joint 26 can protrude upward from upper end cover 3, make to there is space between hook-shaped groove 30 and upper end cover 3, then connecting joint 26 is hung on the circuit of Awaiting Overhaul, then main sleeve 1 is rotated, the cylindrical part of connecting joint 26 bottom is made to enter in insulating sleeve 2 downwards, limited cover 31 on connecting joint 26 and upper end cover 3 are formed closed, prevent the circuit of Awaiting Overhaul from departing from from the hook-shaped groove 30 of connecting joint 26, then, pull out the safe bearing pin 23 closed a floodgate on locking assembly and brake-dividing locking assembly, operator drop to ground by holder device. by the time by-pass line is all after setting completed, the draw ring 18 closed a floodgate on locking assembly is pulled by drag hook, the intermediate bars that making closes a floodgate locks assembly T-shaped pin 19 departs from from the jack 22 of copper row 13, under the elastic force effect of combined floodgate energy-stored spring 9, dynamic contact 6 upwards moves fast, until the cylindricality plug 25 on dynamic contact 6 top enters in the annular slot of static contact 5 bottom so that circuit closes. after circuit is closed, electric current conducts to interior shack 27 and outer shack 28 from Awaiting Overhaul circuit by connecting joint 26, then contact tube 7 is transferred to, the lower end of contact tube 7 is connected with static contact 5, current delivery is to static contact 5, and transfer to dynamic contact 6 by static contact 5, arrange 13 by copper and transfer to conducting block 15, then transfer to by-pass line or ground connection by the bypass connection terminal 16 of connection on conducting block 15. after line maintenance terminates, operator pull the draw ring 18 on brake-dividing locking assembly by drag hook, the intermediate bars of the T-shaped pin 19 of brake-dividing locking assembly is departed from from the jack 22 of push rod 33, under the effect of point lock energy-stored spring 10, piston rod 35 moves downward, piston 11 is driven to move downward, union lever 34, sleeve pipe 12, dynamic contact 6, push rod 33 and copper row 13 move down simultaneously, dynamic contact 6 separates with static contact 5, when piston 11 moves under the promotion of point lock energy-stored spring 10, air-flow can be produced, air-flow is by the through hole 36 on static contact 5, arrive the annular slot position of static contact 5, by dynamic contact 6 and the arc extinction produced during static contact 5 points of locks. after power-off, operator are risen to below maintenance circuit by holder device, rotate main sleeve 1, spun off by maintenance circuit, taken off by portable single-phase air bypass switch in the hook-shaped groove 30 of connecting joint 26. the portable single-phase air bypass switch structure of the present invention simplifies, and eliminates clutch part, weight saving, convenient operation librarian use. dynamic contact with the way of contact of static contact compared with traditional tooth contact mode, contact surface increases, the contact of dynamic contact and static contact is better, when dynamic contact is separated with static contact, contact position can produce electric arc, the static contact of the present invention is provided with the through hole of ventilation, when dividing lock, lock energy-stored spring is divided to promote piston rod and piston to move up, mass air flow can be produced, this part air-flow passes from through hole, arrival static contact and dynamic contact divide the position of lock, the electric arc produced is blown out, arranged by this kind, can prevent contact position from burning out, extend work-ing life.Arranged the dynamic contact of conducting and conducting block by copper, compared with traditional use copper stranded conductor, more firmly, and copper row is better with the electrical contact of conducting block, is conducive to improving the quality of bypass switch. Copper row is provided with handle, more easily operates compared with conventional draw ring, and more firm. In static contact, it is provided with spring touch finger, it is possible to strengthen the electrical connection of static contact and static contact, in conducting block, be provided with spring touch finger, enhances the electrical connection of copper row with conducting block, it is to increase the stability of bypass switch. In use, operator can carry out closing operation and sub-switching operation to the portable single-phase air bypass switch of the present invention on ground, easy to operate, and security is better.
Above embodiment is the explanation to the specific embodiment of the present invention; but not limitation of the present invention; person skilled in the relevant technique is without departing from the spirit and scope of the present invention; can also making various conversion and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes all should be included into the scope of patent protection of the present invention.
