Embodiment Construction

[0009] The present invention will be further described below in conjunction with a preferred embodiment and accompanying drawings.

[0010] as attached figure 1 , attached Figure 2A , 2B As shown, this embodiment is mainly composed of a rubber sleeve 1, a spring 2, a fan-shaped contact piece 3, a grid piece 4, a ground wire group 5, and an aluminum tube 6. The fan-shaped contact piece 3 is installed in the slot of the grid piece 4, and then They are fixed together by a spring 2 to form a fan-shaped contact 7 . Install aluminum tubes 6 at both ends of the inner cavity of the rubber sheath 1, then insert sector contacts 7, and then install a ground wire group 5 in the middle of its outer surface to form a busbar connector. After the above-mentioned structure is adopted in the present invention, the busbar connector has a strong flow capacity, can meet the requirements of a switchgear with a rated current of 1250A when combining cabinets, and has a design use margin of 1.2 ti...

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: [0001] The invention relates to the technical field of insulators used in gas-insulated metal-enclosed switchgear of 24kV and below, in particular to a busbar connector. Background technique: [0002] In the process of design, installation and use of 24kV and below gas-insulated metal-enclosed switchgear, the splicing mode between switchgear, the design and selection of insulating parts and the control of installation quality have always been considered by product designers and engineering installers. This is because the technical index of the insulating part is the bottleneck of the overall equipment performance index. Only by improving the technical level of the insulating part can the technical level of the overall equipment be improved, and the safety and stability of the overall equipment operation can be improved. Existing busbar connectors: ①The contacts are composed of sheet contacts. Under the same installation and use conditions, the contacts of th...
