Embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following execution mode.
See Fig. 1-Fig. 4, single-phase bypass contactor has the boxlike insulating support 3 of an open type, wooden partition middle part in one end of insulating support 3 has a hole, the quiet end of the vacuum interrupter 4 of contactor is installed screw rod 2 and is passed from this hole, and is fixed on insulating support 3 together with cover quiet terminated line copper bar 1 thereon.In the movable contact rod 6 of vacuum interrupter 4, cover has conductive clip 7, on conductive clip 7, be fixed with flexible-connection copper strip 5, flexible-connection copper strip 5 arrives the other end of insulating support 3 through the bottom of insulating supports 3, and is fixed on together with moved end copper busbar 19 with bolt in a fixation wall 17 of insulating support 3.In the movable contact rod 6 of vacuum interrupter 4, also connecting an insulator 10, insulator 10 is cup-like structure, on the close position of rim of a cup, also has the protruding annulus of a circle, be fixed wtih a metal plectrum 11 at the end face of annulus, the shape of metal plectrum is identical with the shape of insulator cup-shaped port, but respectively there is an outwardly directed plectrum plate on both sides, plectrum plate has reached in the square hole on two sides of insulating support 3, and has been pressed on the pressure spring plate of the auxiliary switch 20 that is fixed on insulating support 3 outsides.Auxiliary switch 20 can be exported and often open or normally closed contact.The inner side of insulator 10 is connecting the output ejector pin 8 of a spring operating mechanism, and on output ejector pin 8, cover has a main driving spring 12.The other end of output ejector pin 8 passes from the middle part of support 13, and one end of main driving spring 12 has just withstood on support 13.14 point of three face of support 13 use screw is fixed on insulating support 3.There is a lock nut end at the output ejector pin 8 through support 13, and this lock nut is pinned by a mechanical lock.Mechanical lock has a support 13, has a slideway 15 on support 13, and slideway 15 is wrapping a slide block 22, and slide block 22 can slide up and down in slideway 15, and while sliding into inside the lock nut of output ejector pin 8, just output ejector pin 8 has been pinned.Now, need a magnetictrip to carry out release.The structure of magnetictrip is such: on slide block 22, have a hole, in hole, be inserted with a driving lever 23, driving lever 23 is connected to by a connecting rod on the movable yoke plate 25 of magnetictrip, movable yoke plate 25 is contained on a U-shaped yoke 28, an iron core 26 is housed in the middle of the bottom of yoke 28, on iron core 26, cover has a back-moving spring 27, have a coil 24, and yoke 28 use bolts 29 is fixed on the side of insulating support 3 in the outer surface cover of back-moving spring 27., there is the boss 9 of a strip at rim of a cup annulus place in the bottom inside of insulating support 3 near insulator 10.The lead-out wire terminal of coil 24 is equipped with one and is flexibly connected socket 30.The lead-out wire terminal of auxiliary switch 20 is equipped with and is flexibly connected socket 31 and 32.
The course of work of single-phase bypass contactor:
Before contactor work, need, by main driving spring 12 energy storage,, also the dynamic and static contact of vacuum interrupter be pulled open meanwhile.Its process is: with one, the special spanner of fork-shaped is inserted in the gap between the rim of a cup annulus of insulator 10 and the boss 9 of insulating support 3 bottoms, pull backward spanner, insulator 10 is pulled back, insulator 10 drives the also motion backward of movable contact rod 6 of vacuum interrupter 4, and then the dynamic and static contact of vacuum interrupter is pulled open; And now, the output ejector pin 8 of spring operating mechanism is also along with insulator 10 moves backward, the compressed and energy storage simultaneously of main driving spring 12.Until the lock nut of output ejector pin 8 ends is while moving to the outer end of slide block 22 of mechanical lock, slide block 22 is subject to the effect of back-moving spring 27 and the movable yoke plate 25 of magnetictrip, is moved upwards up to the inner side of lock nut, and output ejector pin 8 is pinned, and preparation finishes.When contactor is received adhesive instruction (being adhesive pulse voltage), the magnetictrip of contactor starts action, by the downward adhesive of movable yoke plate 25, movable yoke plate 25 drives driving lever 23 to move downward by connecting rod, discharge the lock nut of output ejector pin 8, output ejector pin 8 is driving the movable contact rod 6 of insulator 10, vacuum interrupter 4 to travel forward, and then completes the adhesive action of contactor, enters adhesive hold mode.And the residue elastic force of main driving spring 12 now still acts in the movable contact rod 6 of vacuum interrupter 4 by insulator 10, for it provides contact operating pressure.Till when the operating state of bypass contactor remains to system always and quits work, then enter the next work period.
The utlity model has following advantage:
1) because the operating mechanism of single-phase bypass contactor of the present utility model is spring operating mechanism, and a mechanical lock and a magnetictrip are increased, make bypass contactor in the time of work, only need be to pulse voltage of magnetictrip, magnetictrip can be opened mechanical lock, the output ejector pin of retracting spring operating mechanism, makes it drive vacuum interrupter to carry out closing operation.This working method, makes bypass contactor just in the moment of work adhesive, just draws a shorter pulse energy from power supply, and after bypass contactor adhesive, has not just re-used electric energy, thereby saved a large amount of electric energy.
2) the integrated organization plans such as insulating support, spring operating mechanism, mechanical lock and magnetictrip have been adopted due to bypass contactor of the present utility model, therefore, its compact conformation, small volume, be particularly suitable for the application of narrow and small occasion, improve the layout density of element, saved taking up room of element.
3) because having adopted vacuum interrupter that capacity relative is larger to substitute, bypass contactor of the present utility model uses air-insulated working contact, thereby save arc-extinction device and dwindled further volume, simultaneously, can make again contactor be applied in the occasion of relatively high power, improve the capacity of equipment.
