Abstract
The utility model relates to a disconnecting switch used for an inflatable cabinet. The disconnecting switch used for the inflatable cabinet comprises a rack final assembly, a rotating shaft, moving contact bases and isolating contact knife assemblies. The moving contact bases are fixed on the rack final assembly via the insulators, the isolating contact knife assemblies are sleeved on the rotating shaft and are electrically connected with the moving contact bases via the connecting members. The disconnecting switch used for the inflatable cabinet is characterized by also comprising the grounding contact bases which are fixedly connected with the rack final assembly. Each isolating contact knife assembly comprises two isolating contact knives, two baffles and two elastic components, the two isolating contact knives are located between the two baffles, and each elastic component is arranged between each baffle and each isolating contact knife. The lower ends of the two isolating contact knives are contacted with the connecting member, the two baffles are fixedly connected via a screw, and the elastic components are located in the compression states. The advantages of the utility model are that: the overall size of the disconnecting switch is reduced, the safety distance is increased, the requirement that the space of the inflatable cabinet is small is satisfied, the disconnecting switch can be disconnected totally, and the safety performance is improved substantially by designing the disconnecting switch and a grounding switch integrally.
Description
Technical field
The utility model relates to electric field, refers to especially a kind of gas-filling cabinet isolating switch.
Background technology
Existing gas-filling cabinet applies to electric utility widely with isolating switch, and there are following 3 shortcomings with isolating switch in existing gas-filling cabinet: 1, existing gas-filling cabinet is used isolating switch size more greatly, make cupboard size amplification just can pack isolating switch into, lost the little advantage of gas-filling cabinet volume; 2, the electric current that existing gas-filling cabinet is 630A by the capacity major part of isolating switch, general user's power consumption sharply increases now, in the urgent need to jumbo on-load switch; 3, existing isolating switch transmission process is many, this type of switch because of many transmissions of parts node many, manual operation power is large, is not suitable in the gas-filling cabinet of miniaturization.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide the gas-filling cabinet that a kind of overall dimensions is less, capacity is larger and simple in structure isolating switch.
The technical solution of the utility model is achieved in that a kind of gas-filling cabinet isolating switch, comprise frame general assembly, rotating shaft, moving contact seat, and isolation contact knife assembly, described moving contact seat is fixed in frame general assembly by insulator, this isolation contact knife assembly is sheathed on rotating shaft, this isolation contact knife assembly is electrically connected to moving contact seat by connector, it is characterized in that: also include ground contact seat, ground contact seat is fixedly connected in frame general assembly, described isolation contact knife assembly comprises two isolation contact knifes, two baffle plates and two groups of elastic components, two groups of described isolation contact knifes arrange between two groups of blocks, and two groups of elastic components arrange respectively between block and isolation contact knife, the lower end of two groups of described isolation contact knifes contacts with connector, and by screw, be fixedly connected with between two groups of baffle plates, elastic component is in compressive state.
By adopting technique scheme, only need to rotate rotating shaft and just can realize the closure of this isolating switch, greatly reduced the overall dimensions of isolating switch, increase safe distance, meet the little requirement in gas-filling cabinet space, just can cut off completely, and isolating switch and earthed switch integrated design, security performance greatly improved.
The utility model is further set to: also include sleeve pipe, this sleeve pipe arranges between two groups of isolation contact knifes, and is sheathed on screw.
By adopting technique scheme, prevent from isolating contact knife under the effect of elastic component, the upper end of isolation contact knife slopes inwardly, and topology layout is more reasonable.
The utility model is also further set to: described elastic component is leaf spring.
By adopting technique scheme, the thrust of leaf spring is larger, has guaranteed that isolating switch and connector are all the time in connection status.
The utility model is also further set to: on described rotating shaft, be provided with three groups of isolation contact knife assemblies, between adjacent isolation contact knife assembly, be provided with insulator.
By adopting technique scheme, greatly improved the insulation property of lid isolating switch, and simple in structure, be easy to realize.
