Abstract
The utility model relates to high-voltage electric appliance switch equipment, in particular to an isolation switch assembly of a high-voltage vacuum disconector, and aims at providing a vacuum disconnector which is simple in structure, reliable, small in space occupancy. The vacuum disconnector comprises a vacuum assembly, an isolation switch assembly, a fixed contact and a ground contact. The vacuum assembly comprises a load switch transmission shaft, an over-travel device, a vacuum pipe and insulation clamping plates. The insulation switch assembly comprises a support fixedly connected with the insulation clamping plate, a transmission shaft rotatably connected with the middle of an isolating support, a crank connected with the transmission shaft, a connection rod connected with the crank and a movable contact rod connected with the connection rod. One end of the movable contact rod is rotatably connected with the fixed contact, and the other end is provided with a movable contact.
Description
Technical field
The utility model relates to the high-voltage appliance switch control appliance, the special switch component that relates to high-pressure vacuum breaker.
Background technology
Vacuum circuit-breaker because of its arc-extinguishing medium and arc extinguishing after the dielectric in contact gap all be that high vacuum is gained the name; It has volume little, in light weight, be applicable to the advantage that frequent operation, arc extinguishing need not overhaul, in power distribution network, use comparatively universal.Vacuum circuit-breaker mainly comprises three parts: vacuum interrupter, electromagnetism or spring operating mechanism, support and other parts.
Isolating switch and vacuum circuit-breaker are used, and as parts of circuit breaker, its effect is to break off uncharge electric current, circuit to the actual industrial product, makes the equipment and the power supply that are overhauled that tangible cut-off point arranged usually, to guarantee maintainer's safety.Isolating switch does not have special arc-control device can not cut off load current and short circuit current, so must just can disconnecting switch operation under the situation of circuit breaker open circuit at circuit.So isolating switch mainly is used for the part that needs in the high voltage distribution installation to have a power failure is isolated with live part reliably, to guarantee the safety of service work.
The utility model content
The purpose of the utility model provides a kind of simple in structure, reliable, and less vacuum circuit-breaker takes up space.
The utility model is that the technical scheme that achieves the above object is:
A kind of vacuum circuit-breaker; Have vacuum subassembly, switch component, fixed contact and grounding contact; Vacuum subassembly comprises on-load switch power transmission shaft, excess of stroke device, vacuum tube and cleat insulator; Above-mentioned switch component comprises the support that is fixedly connected with cleat insulator, power transmission shaft, the crank that is connected with power transmission shaft, connecting rod that is connected with crank and the movable feeler lever that is connected with connecting rod that is rotatably connected on the isolation mount middle part; One end and the fixed contact of movable feeler lever are rotationally connected, and the other end has moving contact.
Above-mentioned connecting rod is the arc strip, and is provided with bar hole, and the middle part of connecting rod and movable feeler lever is rotationally connected.
The support of above-mentioned switch component is bar shaped, vertically is provided with on the whole, and the support interlude is to deflecting away from away from the grounding contact direction.
The benefit of the utility model is that the switch component support of vacuum circuit-breaker vertically is provided with, and it is less that isolation power transmission shaft, crank and connecting rod linkage process take horizontal space, can save the lateral dimension of vacuum circuit-breaker.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed description.
Fig. 1 is the structural representation of the utility model vacuum circuit-breaker isolating switch "on" position.
Fig. 2 is the structural representation of isolating switch off-state.
Fig. 3 is the structural representation of isolating switch ground state.
Embodiment
See Fig. 1; The utility model vacuum circuit-breaker comprises vacuum subassembly 1, switch component 2, fixed contact 3 and grounding contact 4; Vacuum subassembly comprises on-load switch power transmission shaft 11, be flexible coupling 12, excess of stroke device 13, vacuum tube 14 and cleat insulator 15, and vacuum tube is used for forming switch closure or produces the vacuum interrupter of electric arc when breaking off.Above-mentioned switch component comprises the support 21 that is fixedly connected with cleat insulator, the power transmission shaft 22 that is rotatably connected on the isolation mount middle part, the crank 23 that is connected with power transmission shaft, the connecting rod 24 and the movable feeler lever that is connected with connecting rod 25 that are connected with crank; One end and the fixed contact of movable feeler lever are rotationally connected, and the other end has moving contact.
Above-mentioned connecting rod is the arc strip, and is provided with bar hole, and the middle part of connecting rod and movable feeler lever is rotationally connected.The support of above-mentioned switch component is bar shaped, vertically is provided with on the whole, and the support interlude is to deflecting away from away from the grounding contact direction.
The movable feeler lever 25 of switch component 2 is in "on" position among Fig. 1, and the moving contact of movable feeler lever cooperates connection with the fixed contact of vacuum circuit-breaker, and this moment, vacuum circuit-breaker was a normal operating conditions.See Fig. 2, when needs broke off isolating switch, power transmission shaft rotated, and crank rotates counterclockwise, and promoted the motion counterclockwise together of connecting rod, movable feeler lever, and isolating switch breaks off.See Fig. 3, movable feeler lever rotates counterclockwise around fixed contact under the power transmission shaft effect, up to cooperate connection with grounding contact.
Obviously, the above-mentioned embodiment of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the utility model execution mode.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also be easy to make other pro forma variation and perhaps substitute, and these change or alternative also will being included within the definite protection range of the utility model.
