Description

Cabinet type gas-insulated switchgear device
Technical field
The utility model relates to the high-voltage appliance switch control appliance, the special cabinet type gas-insulated switchgear of high pressure that relates to.
Background technology
Ac high-voltage metal enclosed switchgear (being called for short the inflation cabinet) is the totally-enclosed charger of stainless steel that adopts welding, inflation, leak hunting technology to produce, and its all live parts all are sealed in the Stainless Steel Shell that is filled with sulfur hexafluoride gas.But adopt modularized design not only compactness but also independent assortment, expansion, flexible design, also configurable combined electrical apparatus unit and breaker unit.Product is applied to the construction and the transformation of urban distribution network, is applicable to ring network power supply and the terminal power supply of each distribution system, also is suitable for pack into easy assembling type transformer station, power distribution station, has totally-enclosed, non-maintaining, compact conformation, high reliability features.
Gas-insulated switch adopts the gas in insulation system and the non-atmosphere to make dielectric, and the high voltage device size is able to minification, in cabinet type container, arranges, collection dress degree is high, makes device miniaturization.Insulating gass such as SF6, mist or compressed air are adopted in the current-carrying part sealing of switch major loop, and with the high-pressure electrified conductor sealing, environmental resistance is good, receives the influence of external environment less, and sealing problem is better, and air-tightness can reach 30 years without tonifying Qi.
The utility model content
The purpose of the utility model provides a kind of simple in structure, reliable, and less cabinet type gas-insulated switchgear device takes up space.
The utility model is that the technical scheme that achieves the above object is:
A kind of cabinet type gas-insulated switchgear device; Have vacuum subassembly, switch component, fixed contact and into and out of thread casing; Vacuum subassembly comprises on-load switch power transmission shaft, excess of stroke device, connecting rod insulator, is flexible coupling, vacuum tube and cleat insulator; Above-mentioned switch component comprises the support that is fixedly connected with cleat insulator, is rotatably connected on the terminal power transmission shaft of isolation mount, with the movable feeler lever that fixed contact is rotationally connected, an end of movable feeler lever has the moving contact that can cooperate with the fixed contact on being located at cleat insulator.
The support of above-mentioned switch component is bar shaped, is obliquely installed with vacuum tube, and the support end is to deflecting away from away from the fixed contact direction.
Above-mentioned outlet sleeve pipe and be flexible coupling between be provided with copper rod, entrance bushing is an internal cone type.
The benefit of the utility model is the switch component riding setting of switching device, isolates grounding contact and is located at the vacuum subassembly side, can save the vertical dimension of switch; The internal cone type entrance bushing is positioned at the fixed contact below, and it is reliable to guarantee that inlet wire connects.
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 switching device 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 cabinet type gas-insulated switchgear device of the utility model comprises vacuum subassembly 1, switch component 2, fixed contact 3 and into and out of thread casing 4,5; Vacuum subassembly comprises on-load switch power transmission shaft 11, excess of stroke device 12, connecting rod insulator 13, be flexible coupling 14, vacuum tube 15 and cleat insulator 16, 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, is rotatably connected on the terminal power transmission shaft 22 of isolation mount, the crank that is connected with power transmission shaft, the connecting rod and the movable feeler lever that is connected with connecting rod 23 that are connected with crank; One end and the fixed contact 3 of movable feeler lever are rotationally connected; The other end has moving contact, cooperates connection with the fixed contact that is fixed on the cleat insulator right side 24.Isolate grounding contact 25 and be located at the fixed contact top.
The support of above-mentioned switch component is bar shaped, is obliquely installed with vacuum tube, and the support end is to deflecting away from away from the fixed contact direction.Above-mentioned outlet sleeve pipe 5 is provided with copper rod 6 and is connected with being flexible coupling between 14, entrance bushing 4 is an internal cone type, connects more firm.
The movable feeler lever 23 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 clockwise rotates, and pulling connecting rod, movable feeler lever be motion clockwise together, and isolating switch breaks off.See Fig. 3, movable feeler lever clockwise rotates 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.
