Abstract
The invention relates to a busbar connector used in a gas-insulated metal-enclosed switchgear of 24 kV or less than 24 kV. The busbar connector mainly comprises a rubber sleeve, a spring, a sectorial wafer, a grid plate, a ground wire group and aluminum tubes, wherein the sectorial wafer is arranged inside a clamping groove of the grid plate, and the sectorial wafer and the grid plate are fixed with each other by the spring to form a sectorial contact; and the aluminum tubes are arranged on both ends of an inner cavity of the rubber sleeve, the sectorial contact is inserted into the rubber sleeve, and the ground wire group is arranged in the middle of the outer surface of the rubber sleeve, so that the busbar connector is formed. The gas-insulated metal-enclosed switchgear of 24 kV or less than 24 kV using the busbar connector to assemble machine cabinets has good discharge current capability, a compact structure, reliable quality and superior insulating property, and improves the stability and the safety of equipment operation.
Description
Technical field:
The present invention relates to the insulating part technical field used in 24kV and the following Cubicle Gas-Insulated Switchgear, refer in particular to a kind of bus tie.
Background technology:
In the process that the design and installation of 24kV and following Cubicle Gas-Insulated Switchgear are used, the control of the connecting method between the switchgear, the design selection of insulating part and installation quality thereof, it is the emphasis that product design personnel and project installation personnel consider always, this is because the technical indicator of insulating part is the bottleneck of integral device performance index, have only the technical merit of insulating part has been improved, the technical merit of integral device could be improved, the fail safe and the reliability of integral device operation could be improved.Existing bus tie: 1. contact is made up of the sheet contact, and the contact of this structure is under the same condition of installing and using, and through-current capability is low, and rated current can only reach 630A.Since the continuous high speed development of national economy, the continuous increase of power consumption, the performance index of user's switching devices propose higher requirement, and low rated current has limited the development and the application of Cubicle Gas-Insulated Switchgear.2. the inner chamber of rubber sleeve does not have the aluminum pipe of support.Switchgear is when splicing, and the insulation coordination of bus tie and bus-bar insulator is the key that guarantees its electric property, and lacks the bus tie that supports aluminum pipe that the interfacial pressure of insulation coordination will can not get reliable assurance.3. the product structure size is big.The physical dimension of bus tie directly has influence on the cabinet size and the manufacturing cost of switchgear, and big physical dimension will make the cabinet size of switchgear become big, increases product cost.So, a kind of novel bus tie of development and Design, the key of technical quality level when being raising and assurance Cubicle Gas-Insulated Switchgear assembly cabinet.
Summary of the invention:
The objective of the invention is to overcome the weak point of existing product technology, a kind of bus tie is provided, using this bus tie, to piece together the 24kV and the following Cubicle Gas-Insulated Switchgear through-current capability of cabinet good, compact conformation, reliable in quality, have good insulation property simultaneously, improve operation stability of equipment and fail safe.
For achieving the above object, technical scheme provided by the invention is: mainly be made of rubber sleeve, spring, fan-shaped contact, grid sheet, earth connection group, aluminum pipe, fan-shaped contact is contained in the draw-in groove of grid sheet, they are fixed together by spring handle then, form fan-shaped contact.The aluminum pipe of packing at the inner chamber two ends of rubber sleeve inserts fan-shaped contact again, loads onto the earth connection group in the middle part of its outer surface then, constitutes bus tie.
After the present invention adopts said structure, the through-current capability of bus tie is strong, because this version of fan-shaped contact, the contact-making surface and the cross section of conductor have been increased, greatly improve the through-flow performance of bus tie, requirement when satisfying rated current 1250A switchgear assembly cabinet, and have 1.2 times design to use nargin.Bus tie has good insulation property, bus tie by with switchgear in bus-bar insulator be connected cooperation, realize the assembly cabinet of switchgear, because the supporting role of aluminum pipe, the insulator interface pressure of bus tie and bus-bar insulator is guaranteed reliably, also improved the insulation level of integral device, made the operation of equipment more stable and safer.Simultaneously, the bus tie volume is little, and compact conformation makes the cabinet small designization of switchgear, reduces product cost.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2A, 2B are the structural representation of the fan-shaped contact of the present invention;
Accompanying drawing 3 is for using the structural representation that the present invention pieces together cabinet.
Embodiment:
The present invention is described further below in conjunction with a preferred embodiment and accompanying drawing thereof.
Shown in accompanying drawing 1, accompanying drawing 2A, 2B, present embodiment mainly is made of rubber sleeve 1, spring 2, fan-shaped contact 3, grid sheet 4, earth connection group 5, aluminum pipe 6, fan-shaped contact 3 is contained in the draw-in groove of grid sheet 4, by spring 2 they is fixed together then, form fan-shaped contact 7.The aluminum pipe 6 of packing at the inner chamber two ends of rubber sleeve 1 inserts fan-shaped contact 7 again, loads onto earth connection group 5 in the middle part of its outer surface then, constitutes bus tie.After the present invention adopted said structure, the through-current capability of bus tie was strong, the requirement in the time of satisfying rated current 1250A switchgear assembly cabinet, and have 1.2 times design to use nargin.Simultaneously, bus tie has good insulation property, as shown in Figure 3, bus tie by with switchgear 8 in bus-bar insulator 9 be connected cooperation, realize the assembly cabinet of switchgear, because the supporting role of aluminum pipe 6, the insulator interface pressure of bus tie and bus-bar insulator is guaranteed reliably, also improved the insulation level of integral device, made the operation of equipment more stable and safer.In addition, the bus tie volume is little, and compact conformation can make the cabinet small designization of switchgear, reduces product cost.
The embodiment of the above is preferred embodiment of the present invention only, is not to limit practical range of the present invention with this, so all equivalences of doing according to shape of the present invention, structure and principle change, all should be covered by within protection scope of the present invention.
