Abstract
The utility model relates to a solid insulation bus connector for a gas insulated metal sealing switchgear of sulfur hexafluoride (SF#-[6]). The utility model is characterized in that a silicon rubber sleeve 3 is inserted between a cabinet body bus bushing 1 and a bus 11; the cabinet body bus bushing 1 is inserted into a concave groove of a cabinet body side plate 8; a flange plate 9 is welded on the cabinet body side plate 8; a sealing ring 10 is arranged in the concave groove of the cabinet body side plate 8, is fixed by a press plate 7, and is fixed by a flat gasket 4, an elastic gasket 5 and a screw nut 6; two spring contact fingers 2 in opposite revolving directions are arranged in a copper embedded member of the cabinet body bus bushing 1. The utility model has the advantages that the use of solid insulating materials as external insulation can enable electric field distribution to be more reasonable, give full play to the potential of different insulating mediums, and effectively decrease the size of an insulation structure. The utility model only needs a gap of 10 mm to be left between two surface cabinets, and no other space is occupied, which reduces the installation space.
Description
Technical field
The utility model relates to a kind of sulphur hexafluoride (SF that is used for
6) the solid insulation bus tie of Cubicle Gas-Insulated Switchgear, belong to the technical field of High-Voltage Electrical Appliances.
Background technology
The SF of early development
6Cubicle Gas-Insulated Switchgear, bus generally are inflation bus or cable bus.There are the on-the-spot defectives such as difficult, that autgmentability is poor, cannot plug of installing in they.Recent years, develop a kind of solid insulation bus abroad, solved above-mentioned shortcoming.It is big that but its existence takes up room, and installation accuracy requires high, shortcomings such as cost height.Limited its occupation rate of market.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of new Ying's structure and is used for SF
6The solid bus tie of Cubicle Gas-Insulated Switchgear.It has take up room little, characteristics such as installation accuracy requires and cost is low.Solution of the present utility model: silicone rubber sleeve inserts between cabinet bus casing and the bus, and the cabinet bus casing is inserted in the groove of side cabinet, in the opposite copper insert that is contained in the cabinet bus casing of two spring touch finger rotation directions.
With the external insulation of epoxy resin as the cabinet bus, bus is to utilize silicone rubber sleeve to insert between cabinet bus casing and the bus with the connection of cabinet.Utilize the elasticity of silicon rubber that the air gap between silicone rubber sleeve and cabinet bus casing, silicone rubber sleeve and the bus is squeezed out.Thereby the purpose that reaches insulation and dwindle insulation distance.Advantage of the present utility model: use solid insulating material as external insulation, make Electric Field Distribution more reasonable, given full play to the potentiality of different insulative medium.Effectively reduced the size of insulation system.The utility model only needs to reserve between the cabinet of two sides the space of 10mm, does not take other space.Reduced installing space greatly.
Appended drawings is a structural representation of the present utility model.
Among the figure 1 is cabinet bus casing, the 2nd, spring touch finger, the 3rd, silicone rubber sleeve, the 4th, plain washer, the 10, the 5th, spring washer, the 10, the 6th, nut M10, the 7th, pressing plate, the 8th, side cabinet, the 9th, the blue dish of method, the 10th, sealing ring, the 11st, bus.
Embodiment
The contrast accompanying drawing, the blue dish 9 of method is welded on the side cabinet 8, and sealing ring 10 is installed in the groove of side cabinet 8; Cabinet bus casing 1 is inserted in the groove of side cabinet 8, fixing and fastening with pressing plate 7 with plain washer 4, spring washer 5 and nut 6; In the copper insert that is contained in cabinet bus casing 1 that two spring touch finger 2 rotation directions are opposite.
When the two sides cabinet splices bus 11 1 ends are inserted in the spring touch finger 2, again silicone rubber sleeve 3 one ends are inserted between bus 11 and the cabinet bus casing 1.Then the another side cabinet is advanced, bus 11 1 ends are inserted in the spring touch finger 2, silicone rubber sleeve 3 one ends insert between bus 11 and the cabinet bus casing 1.Use the splicing screw of two sides cabinet fastening at last, the end face of the blue dish 9 of method is developed.
Bus tie is the element that the galvanic circle of two sides cabinet is connected.And to guarantee that the gas-insulated medium in the cabinet is not leaked to the cabinet outside.Cabinet bus casing 1 casting epoxy resin outside copper busbar constitutes.Mounting spring fingertip 2 in the groove of copper busbar inserts bus 11 in the spring touch finger 2.Form reliably between copper busbar, spring touch finger 2 and the bus 11 of power in cabinet bus casing 1 that 2 distortion produce by spring touch finger and be electrically connected; The other end is electrically connected because of same principle forms.The galvanic circle of two sides cabinet has just been connected.
The blue dish 9 of method is welded on the side cabinet 8, and its outside can not produce leakage because of firm welding.Side is because of between cabinet bus casing 1 and the blue dish 9 of method sealing ring 10 being installed, so also can not reveal.The inside and outside sealing problem of cabinet has also solved.
Cabinet bus casing 1 is installed in cabinet inside, and insulation solves by solid insulating material; The connection of two sides cabinet is to utilize silicone rubber sleeve 3 to insert between cabinet bus casing 1 and the bus 11, utilize the elasticity of silicon rubber that the air gap between cabinet bus casing 1 and silicone rubber sleeve 3, silicone rubber sleeve 3 and the bus 11 is squeezed out, between the three, form the interface insulation of solid material.Therefore Insulation Problems has solved.
Claims (1)
