Description
Technical field:
The utility model relates to power switch, and particularly high pressure is isolated in the on-load switch combined operation mechanism to the vacuum interrupter separating brake.
Background technology:
In power distribution equipment, adopt vacuum interrupter switch realize the continuing electric break-make of circuit and each branched line usually.And vacuum interrupter requires that on/off operation mechanism is faster arranged, to realize arc quenching effect preferably.But in existing these class auxiliary products, such as the outdoor pole vacuum circuit breaker of commercially available ZW-12/T630-20 type, general employing extension spring, drive extension spring by a control lever shaft, when peaking, extension spring just releases energy, branch, closing speed still need further to improve, in addition, because this structure of existing product causes volume to amplify the cost height.
Summary of the invention:
The purpose of this utility model provides a kind of combined operation mechanism that can make the higher opening velocity of vacuum interrupter, and volume is less, and connecting-disconnecting function is big, and fail safe is good.
The utility model comprises the positive housing that is connected with the porcelain insulating pipe, it is characterized in that connecting lever has a lever fulcrum, its resistance arm connects with pull bar and stage clip guide rod radial peg successively, the pull bar front end can connect with moved end, the contact spiral shell of vacuum extinction pipe in the porcelain insulating pipe, stage clip pushes up mutually with the connecting lever resistance arm, the power arm top of connecting lever is made arc and is pushed up mutually with the semiaxis that torsion spring is housed, and cam and semiaxis constitute tripping mechanism.Laterally the short screw through the semiaxis axle body pushes up mutually with cam wheel edge.
Above-mentioned connecting lever constitutes parallel combination by second mate's connecting lever, and each connects pull bar and stage clip guide rod by the pin pin respectively between two resistance arms.Pull bar is determined by 13 ± 2mm by the distance that seesaws with pull bar to the distance of connecting lever fulcrum, the terminal extended housing bonnet of pull bar.
The utility model is because connecting lever resistance end pushes up mutually with the separating brake stage clip, and the cam tripping mechanism makes after need turning an angle semiaxis and connecting lever thread off, and also is that isolation knife need be lifted the stored energy ability rapid release of separating brake stage clip behind the certain angle; When isolation knife was closed a floodgate, the separating brake stage clip had begun storage power again, also was that separating brake institute energy requirement prestores, and the energy of prior art provides immediately, obviously can improve opening velocity, has guaranteed good arc quenching effect, and electric life prolongs.Owing to cancelled traditional joystick and extension spring, make structure more reasonable, compact in addition, production cost also reduces.
Description of drawings:
Rearview when Fig. 1 is unkitted bonnet for the utility model.
Fig. 2 is Figure 1A-A sectional view (comprising bonnet).
Embodiment:
In conjunction with Fig. 1.Housing with porcelain insulating pipe 16 composition surfaces be the front.Parallel longitudinal connecting lever group 5a, 5b are housed in the housing 1, and its rotating fulcrum 6 crosses the housing two side, and connecting lever group resistance arm end is clamping pull bar 3 and stage clip guide rod 12 successively, runs through being rotatably connected respectively with pin 4 and pin 2.Rotating fulcrum 6 parallel beneath installation shaft have the semiaxis 11 that circle lacks on one's body, and its circle lacks power arm termination that the place is positioned at connecting lever 5a, the circular arc end face of connecting lever 5a can snap in this circle scarce in.Cross short screws 8 in the middle of being with the semiaxis 11 of torsion spring 7, semiaxis 11 parallel beneath are installed camshaft 10, and housing sidewall is run through at its two ends, and the middle short screw 8 of cam 9 far-ends of installing in the middle of it and above-mentioned semiaxis pushes up mutually.
In conjunction with Fig. 2, porcelain insulating pipe 16 internal cavities 17 are used for installing vacuum extinction pipe (figure does not draw), the end of thread of the moving contact of vacuum extinction pipe stretches into from pilot hole 18 with pull bar 3 spiral shells and connects, and pull bar 3 shafts are by the resistance arm stage casing of round pin 4 with pin-connection in the connecting lever group, and the bar end passes housing 1 bonnet.Two rollers 13 are installed on connecting lever group top, and stage clip 15 is enclosed within outside the guide rod 12, and its movable spring seat pushes up mutually with roller 13; Have oval groove 14 on guide rod 12 shafts, the round pin 2 that runs through the connecting lever group top of roller 13 and this groove can reciprocating motion in this groove.The round breach of cam 9 and semiaxis 11 constitutes the tripping mechanism of connecting lever group.
The course of work:
When the needs separating brake, lifting isolation knife and driving camshaft 10 rotates counterclockwise cam 9, cam 9 promotion short screws 8 drive semiaxis 11 clockwise rotate simultaneously, when semiaxis turns to connecting lever 5a top when entering circle and lacking the edge, the energy rapid release that the stage clip 15 that connecting lever resistance arm top is pressed is stored and resistance arm is moved along groove 14 fast backward by roller 13, also drive simultaneously pull bar 4 motion backward fast, realized the dynamic and static contact electric current disjunction of vacuum interrupter.The arc tips of this section process connecting lever slides in semiaxis circle lacks, and finishes the dropout process, and the elastic force that is provided by stage clip 15 automatically locks, and makes fracture obvious.When needs close a floodgate, pressing isolation knife drive camshaft 10 downwards clockwise rotates cam 9, cam 9 trailing edges drive connecting lever 5 by roller 19 and rotate counterclockwise, the connecting lever resistance arm carries out energy storage with stage clip 15 compressions, drive pull bar 3 sinciputs simultaneously, make the dynamic and static contact closure of vacuum interrupter, semiaxis 11 also acts on reinstatements because of torsion spring 7 and makes the connecting lever arc tips break away from circle and lacks, guarantee that combined floodgate is reliable.In the above-mentioned separating brake process, isolation knife is divided earlier, divides behind the arc control device; In making process, arc control device close earlier, close after the isolation knife.
This device both can be manual, also can be equipped with electronics PT, realizes electronic and the enforcement remote control.
