According to the technical scheme of the invention, the operating mechanism is directly in transmission connection with the movable-end conductive rod. In this way, no insulated pull bar is adopted, and the weight of moving parts is reduced. The breaking-closing speed is improved. The first contact is in the form of the floating contact. Therefore, after the closing process, the second contact can push the first contact to move continuously. The elastic piece keeps a certain engagement pressure between the two contacts after being compressed, so that the closing performance is ensured to be good. The condition that the closing performance is affected due to the absence of an over-travel spring after the direct removal of the insulated pull bar can be avoided. Meanwhile, the elastic piece supplies an initial kinetic energy for the breaking of the second contact, so that the breaking speed is improved.

Detailed description of the invention
One embodiment of chopper is as shown in Figure 1, including pole and repulsive force mechanism (not shown), pole includes, by the cast shell 1 of poured with epoxy resin, being vertically respectively arranged with wire outlet seat 14, vacuum interrupter and lower wire outlet seat 10 in cast shell 1.The upper and lower end of vacuum interrupter is respectively arranged with upper cover plate 17 and lower cover 18, is provided with the first contact 6 and the second contact 11 in vacuum interrupter, and the lower section of the second contact 11 connects moved end conducting rod 8, and repulsive force mechanism is directly in transmission connection with moved end conducting rod 8.The periphery of moved end conducting rod 8 is provided with lower corrugated tube 7, and one end of lower corrugated tube 7 is connected on moved end conducting rod 8, the other end is connected on lower cover 18, and the bottom of moved end conducting rod 8 is flexible coupling by lower conduction and 9 is connected with lower wire outlet seat 10.
The upper end of the first contact 6 is provided with conducting rod 5, and the periphery of conducting rod 5 is provided with corrugated tube 4, and one end of upper corrugated tube 4 is connected on conducting rod 5, the other end is connected on upper cover plate 17.The upper end of conducting rod 5 is provided with guide post 15, and the outer cover of guide post 15 is provided with spring 2, and this spring is a kind of common helical spring.Cast shell 1 is provided with cylinder 12 in the periphery of conducting rod 5 and guide post 15, it is provided with conducting rod at the bottom of the cylinder of cylinder 12 and passes through hole, the tube port position capping of cylinder 12 has upper wire outlet seat 14, and upper wire outlet seat 14 is provided with pilot hole 16, and the upper end of guide post 15 guides and is slidedly assemblied in pilot hole 16.It is provided with the upper conduction that one end is connected with upper wire outlet seat 14, the other end is connected with conducting rod 5 between upper wire outlet seat 14 and conducting rod 5 and is flexible coupling 13, the two ends of spring 2 withstand on conduction respectively and are flexible coupling on the connection end at 13 two ends, are equivalent to provide a spring base for spring 2.The upper end of conducting rod 5 is provided with and turns edge 3, and turning edge 3 coordinates with block at the bottom of cylinder to limit the mobile limit that conducting rod 5 moves down.
During use, under the effect of repulsive force mechanism, moved end conducting rod 8 moves upward, the second contact 11 is driven to engage with the first contact 6, along with moved end conducting rod 8 continues up, spring 2 is compressed, when after moved end conducting rod 8 stop motion, spring 2 applies downward reaction force to conducting rod 5, the first contact 6 and the second contact 11 is made to fit tightly, it is achieved to close a floodgate, in this process, all the time there is certain activating pressure between first contact 6 and the second contact 11, therefore there is performance of preferably closing a floodgate.During separating brake, under the effect of repulsive force mechanism and spring 2, moved end conducting rod 8 moves downward, conducting rod 5 also moves downward under the effect of spring 2, when turning edge 3 with when contacting at the bottom of cylinder, conducting rod 5 and the first contact 6 stop motion, along with moving downward of the second contact 11, first contact 6 and the second contact 11 separate, and separating brake completes.
The effect of spring 2, in addition to can being the first contact 6 and the second contact 11 provides activating pressure, when closing a floodgate, owing to spring 2 has sponged a part of kinetic energy of the second contact 11, is therefore also prevented from closing rebound.It addition, when separating brake, spring 2 to reset, provide an initial kinetic energy therefore can to the second contact 11, make the first contact 6 and the second contact 11 can quickly disjunction, the minimizing arc time, improve the service life of opening velocity and component.
The vacuum interrupter of pole is provided with corrugated tube 4 and lower corrugated tube 7, this is owing to the first contact 6 and the second contact 11 can move, bi-bellow ensure that conducting rod 5 and moved end conducting rod 8 excellent sealing effect of vacuum interrupter when motion, thus ensures good arc extinction performance.
Repulsive force mechanism is directly in transmission connection with moved end conducting rod, so may dispense with insulated tension pole, such that it is able to reduce the weight of moving component, be conducive to the raising of circuit-breaker switching on-off speed, the weight of moving component is alleviated after arranging although it is so, but repulsive force mechanism itself is also due to being joined directly together with moved end conducting rod and cause with moved end conducting rod is isoelectric level, i.e. repulsive force mechanism is charged, therefore chopper is in subsequent fabrication process, repulsive force mechanism need to carry out the insulation processing between ground, it is to avoid in use repulsive force mechanism discharges over the ground.
By upper wire outlet seat, nozzle is covered, and it is provided with pilot hole on upper wire outlet seat, do so is due to pole during fabrication, the outside need casting epoxy resin of the parts such as upper wire outlet seat, guide post thus form cast shell, if nozzle does not covers, epoxy resin will be poured into inside cylinder, and arranges pilot hole on upper wire outlet seat, and the guiding up and down thus facilitating guide post is slided.Between upper wire outlet seat and conducting rod, arrange the upper conduction that one end is connected, the other end is connected with conducting rod with upper wire outlet seat be flexible coupling, this is owing to guide post is to guide to be slidedly assemblied in pilot hole, through-flow in order to ensure conduction good between upper wire outlet seat and conducting rod, therefore conduction is set and is flexible coupling.
In other embodiments of chopper: operating mechanism can also be spring operating mechanism or permanent-magnet manipulating mechanism；The upper end of conducting rod can also be not provided with turning edge, but arranges one or two gag lever posts on the outer peripheral face of conducting rod；Conduction can also be not provided with between upper wire outlet seat and conducting rod be flexible coupling, but carry out conducting electricity by guide post through-flow；Elastic component can not be helical spring, it is also possible to is disc spring or rubber；The periphery of conducting rod can also be not provided with corrugated tube, can arrange sliding seal between conducting rod and cast shell.
The embodiment of pole, as it is shown in figure 1, the concrete structure of pole is identical with the pole described in above-mentioned chopper embodiment, is not described in detail in this.
