Embodiment Construction
[0009] Referring to the figure, the structure is that the connector rubber sleeve 1 is inserted between the busbar sleeve 2 and the bus bar 3. The outer side of the connector rubber sleeve 1 is pressed by the pressure plate 6, and the pressure plate 6 is fixed on the cabinet side plate 5 with the B nut 7. The busbar bushing 2 is fixed on the cabinet side plate 5 with A nut 4, and the sealing ring 8 is installed in the groove between the busbar bushing 2 and the cabinet side plate 5, between the busbar bushing 2 and the busbar 3. Conductive spring contact fingers 9 are installed in the semicircular groove.
[0010] The busbar connector is a component that connects the conductive circuit of the two-sided cabinet. And to ensure that the gas insulating medium in the cabinet does not leak to the outside of the cabinet.
[0011] The bus bushing 2 is formed by pouring epoxy resin on the outside of the conductive seat 17, the spring contact finger 9 is installed in the groove of the condu...

The invention provides a bus connector for a cabinet type gas-insulated metal-enclosed switchgear, which is characterized in that a connector rubber sleeve is inserted between a bus bushing and a bus, the outside of the connector rubber sleeve is pressed tightly by a pressing plate, the pressing plate is fixed on a cabinet side plate by a screw nut B, the bus bushing is fixed on the cabinet side plate by a screw nut A, a sealing ring is arranged in a groove between the bus bushing and the cabinet side plate, and a conductive spring contact finger is arranged in a semi-circle groove between the bus bushing and the bus. When the bus connector is used, epoxy resins are taken as external insulation of a cabinet bus, the elasticity of the bus connector rubber sleeve is utilized to edge out air gaps between the rubber sleeve and the bus bushing as well as between the rubber sleeve and the bus. The bus connector has the advantages that solid insulating materials are used as the external insulation, and the electric-field distribution is reasonable, thus the potentials of different insulating media are exerted sufficiently; the self-compensation and adjustment of installation deviation can be realized, and the installation is convenient and reliable, thus the size of an insulation structure is reduced effectively; and only 10mm is reserved between two cabinets, thus saving the space.
Description
Technical field [0001] The invention relates to a bus connector for a cabinet type gas insulated metal enclosed switchgear, belonging to the technical field of cabinet type gas insulated metal enclosed switchgear. Background technique [0002] In the process of designing and installing cabinet-type gas-insulated metal-enclosed switchgear, the splicing method between the cabinet and the cabinet, the design and selection of insulating parts and the control of the installation quality have always been product designers and engineering installers. The key point of consideration is that the insulation is one of the most vulnerable links in the entire equipment, and its technical level directly affects the safety and stability of the overall equipment. In the early development of gas-insulated metal-enclosed switchgear, the bus is generally an inflatable bus or a cable bus. They have defects such as difficulty in on-site installation, poor scalability, and unplugging. In recent years...
