Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the bus connecting sleeve with seal for the gas-filled cabinet provided by the invention comprises a conducting rod 2 and an insulator 1 wrapped outside the conducting rod 2, wherein a flange 8 is arranged on the outer surface of the insulator 1 along the circumferential direction, an installation insert 3 is arranged on the flange 8, a shielding net 4 is arranged in the insulator 1 at a position opposite to the flange 8, and the shielding net 4 is connected with the installation insert 3.
As shown in fig. 3, the insulator 1 is cast into an integral structure by epoxy resin, and the outer surface is coated with an aluminum layer 6, the aluminum layer 6 is connected with the mounting insert 3, and the ground potential is formed after mounting.
As shown in fig. 2, the surface of the conductive rod 2 is subjected to sand blasting to form a sand blasting layer 5, and the surface of the conductive rod 2 after sand blasting is sufficiently rough. The sand-blasting part is wrapped by resin, and the conducting rod 2 is adhered with the solidified resin, so that no gap is left between the resin and the conducting rod 2, and the possibility of gas leakage is eliminated.
The flange 8 is of an annular structure, and a sealing surface 7 is arranged on one side of the flange.
And the mounting insert 3 and the shielding net 4 are welded together, are mounted in a pressure gel mold together with the conductive rod 1, and are injected with liquid epoxy resin at proper temperature and pressure, and a sleeve finished product is obtained after the curing is completed. The sleeve is formed by adopting a pressure gel forming process, so that the sleeve has high insulating strength; the curing temperature and time are controlled in the curing process of the resin, so that the resin can obtain better mechanical strength and can bear higher transverse mechanical bending failure load.
As shown in fig. 3, the outer surface of the insulator 1 is subjected to aluminum spraying, an aluminum layer 6 is formed on the surface of the resin after the aluminum spraying, the aluminum layer 6 is connected with the mounting insert 3, and after the sleeve is mounted on the cabinet body, the aluminum layer 6 is in contact with the cabinet body to form a complete ground potential shielding layer, so that the safety of the cabinet body of the inflatable cabinet is enhanced. And a sealing surface 7 is finely processed on one side of the mounting flange to form a high-precision plane, so that the sealing property of the inflatable cabinet is enhanced.
The invention provides a connecting sleeve with a sealing bus for an inflatable cabinet, which is integrally molded by epoxy resin, is an air-tight connecting device used on the inflatable cabinet, can connect buses inside and outside the cabinet under the condition of not damaging the air tightness of the inflatable cabinet, has enough conductor sectional area to pass through, and forms reliable insulation between the buses and a grounded cabinet body; because the air-filled cabinet is provided with a smooth sealing surface, the air-filled cabinet can be sealed by matching with a sealing ring; the shielding net inside can homogenize the electric field, and avoid the electric field from excessively concentrating and discharging; the part exposed outside the cabinet body is covered with the aluminum layer, so that the outer surface of the aluminum layer and the cabinet body can be connected into a whole, and the grounding of the outer surface is ensured.
The invention adopts advanced epoxy resin, uses APG automatic pressure gel forming process to integrally produce, and the sleeve is formed at one time, so that the surface of the sleeve has good inherent hydrophobicity, transfer hydrophobicity and reduction hydrophobicity. The curing time and temperature are strictly controlled in the resin curing process, so that the mechanical strength of the sleeve reaches the highest. The shielding net is placed inside the sleeve and connected with the three mounting holes, so that the shielding net is grounded, an electric field inside the sleeve is uniform, and partial discharge is reduced. And an aluminum layer is sprayed outside the sleeve, so that the exposed surface can be grounded together with the inflatable cabinet body, and the safety is improved. The inside of the resin is processed by a high-conductivity high-quality copper rod, and the rated current of the sleeve is increased by using a larger sectional area. The mounting surface of the sleeve flange is provided with a plane, so that the sealing performance of the sleeve on the inflating cabinet is improved.
