Fig. 2 is the structural representation of the utility model with another angle of Quick ground switch device of air pressing type structure.
In accompanying drawing: 1-connecting rod, 2-baffle plate, 3-fairlead, 4-piston cylinder, 5-moving contact, 6-insulation board, 7-fixed contact pedestal, 8-piston plate, 9-spring, 10-mechanism connecting plate.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of Quick ground switch device with air pressing type structure, an air pressing type structure more than the high speed grounding switch of routine, and entirety is closed air chamber, comprise dynamic side air chamber and quiet side air chamber, dynamic side air chamber is the piston cylinder 4 of hollow.
Described dynamic side air chamber and quiet side air chamber are separated by insulation board 6.
Described dynamic side air chamber internal fixtion has moving contact 5, this moving contact 5 extends in the air chamber of side in meditation, in described quiet side, air chamber internal fixtion is provided with fixed contact pedestal, and other one end of described moving contact is provided with driving mechanism, and described driving mechanism comprises connecting rod 1 and mechanism's connecting plate 10.Moving contact periphery in the air chamber of described dynamic side is fixed with piston plate 8, and this piston plate 8 is fixedly mounted in piston cylinder 4 by fairlead 3; Described fairlead 3 reliably contacts with piston cylinder inner wall smooth, to ensure that piston cylinder moves reciprocatingly at piston cylinder inwall smoothly under the effect of moving contact.Described actuating force is applied to Grunding switch gear device by mechanism's connecting plate 10.
Described piston cylinder 4 with insulation board 6 is provided with the first pore be communicated with quiet side air chamber, described piston plate is provided with the second through pore, described moving contact be positioned at dynamic side air chamber end and the whole body be provided with multiple 3rd pore.When actuating force is applied by mechanism's connecting plate, mechanism's connecting plate drives moving contact to left movement by connecting rod 1, piston plate is under the drive of moving contact, compression dynamic side air chamber left, by the gas in the dynamic side air chamber that compresses after being subject to compression sharply, moving contact center is flowed to by the 3rd pore on moving contact termination and surface, the whole body, final air-flow by moving contact center from the another end head fracture of dynamic/static contact (i.e. between) ejection, thus the high-voltage arc blowing-out that will produce during high-voltage high-speed grounding switch tripping.
In addition, the inlet end of described moving contact 5 is also arranged with Compress Spring 9 and can baffle plate 2 in axial sliding, and Compress Spring 9 one end is fixed on moving contact 5, and the other end is fixed on baffle plate 2, and described baffle plate 2 is positioned at the side of piston plate away from fracture site.When the space of the dynamic air chamber side, side of piston plate compression, along with by the rising of compression air chamber's internal gas pressure, described baffle plate 2 is close to piston plate under the effect of the pressure, thus is blocked by the second pore on piston plate, ensures to be raised by the pressure durations of compression stroke; After arc extinguishing completes, the high pressure draught of quiet side air chamber gets back to dynamic side air chamber by the second pore, until the air pressure of sound side air chamber is in poised state.
The utility model patent is by means of the principle of blowing out high-voltage arc with air-flow inside arc control device, original high speed grounding switch moving contact is lengthened, increase a piston cylinder dynamic side and quiet side are coupled together, on moving contact, a baffle plate is fixed in a distance, distance termination simultaneously, there is a thin plate above baffle plate, above thin plate, have helical spring to be withstood by thin plate.There is the hole run through, to ensure certain air motion above moving contact simultaneously.
