Problems solved by technology
Since the sprayed shielding layer is very thin, generally less than 0.2mm, its adhesion will decrease significantly over time, it is easy to wear, fall off, and is not resistant to pollution. After a long time, the surface resistance of the shielding layer changes, and it will appear. Ground faults seriously affect the protection performance of the product and greatly shorten the service life of the product
③ No flange steps are designed, and the fixation of the busbar connector is guaranteed by the positioning of the cabinet
When the cabinet body is displaced and the distance between the cabinet bodies changes, because the middle part cannot be stretched, the interface insulation coordination between the busbar connector and the busbar insulator will be affected, causing surface discharge or insulation breakdown accidents

Embodiment Construction
[0008] The present invention will be further described below in conjunction with a preferred embodiment and the accompanying drawings.
[0009] As attached figure 1 As shown, this embodiment is composed of an outer shielding sleeve 1, an insulating layer 2, an inner shielding layer 3. The middle part of the outer shielding sleeve 1 and the insulating layer 2 is designed as a circular arc drum 4, and the outer shielding sleeve 1 is made of semi-conductive silicone rubber. The material is injection-molded, and both ends are respectively designed with raised steps 5, and the inner shielding layer 3 is a spray coating. After the present invention adopts the above structure, the busbar connector rubber sleeve 6 has self-compensation and adjustment functions, as attached figure 2 As shown, when the cabinet-type gas-insulated metal-enclosed switchgear 7 exhibits installation deviations during assembly, the busbar connector rubber sleeve can effectively compensate and adjust these deviat...

This invention is related to a bus connector gum cover used in cabinet gas insulated metal-enclosed switchgear, which is composed of an external shielding sleeve, an insulated layer and an internal shielding layer. The middle part between the external shielding sleeve and the insulated layer is designed to the shape of circular arc drum. The external shielding sleeve is formed by adopting the semi-conductive silicone rubber material by means of injecting and is optimized by the calculation of advanced electric field software. A convex step respectively installed at two ends of the external shielding sleeve is used for being pressed and fixed. The internal shielding layer is a coating layer. The cabinet gas insulated metal-enclosed switchgear using this bus connector gum cover to consolidate is capable of self-compensating and self-adjusting the mounting deviation and has simple mounting, reliable quality, excellent insulated performance and protecting property, and is capable of improving the reliability and safeness of the device.
Description
Technical field: [0001] The invention relates to the technical field of insulating parts used in cabinet-type gas-insulated metal-enclosed switchgear, in particular to a busbar connector rubber sleeve. 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 installation quality have always been product designers and engineering installers. The focus 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. Existing busbar connector rubber sleeve: ①The middle part of the product is designed into a straight barrel shape. This design is very unfavorable for the assembly of cabinet-type gas-insulated metal-enclosed switchgear. Since it cannot be expanded and con...
