Detailed Description
As shown in fig. 1-5, the air-cooled cable joint structure is characterized in that the cable comprises a hollow copper tube 1, the hollow copper tube 1 is used as a center, a single-layer or multi-layer conductor 2 is regularly twisted on the outer layer of the hollow copper tube 1, and an insulating layer 3 is arranged outside the conductor 2. The hollow metal sleeve 4 is placed outside the conductor 2, specifically, the material of the metal sleeve 4 is copper, the inner diameter of the metal sleeve 4 is larger than the outer diameter of the conductor 2, the conductor 2 is welded on the inner wall of the metal sleeve 4 through hydraulic cold welding, so that the metal sleeve 4 can be well connected with the conductor 2, the metal sleeve 4 is provided with a connecting part 5, and the connecting part 5 is connected with electric equipment.
Install rubber embedded pipe 6 in the metal covering 4, rubber embedded pipe 6 mainly is made by hard rubber, has good insulating effect, and intensity is higher simultaneously, and is not fragile, and life is permanent. The metal sleeve 4 is in interference fit with the rubber embedded pipe 6, and the metal sleeve 4 is bonded with the rubber embedded pipe 6 through glue for the connection stability and the air tightness. The rubber embedded pipe 6 is of an integral cylindrical structure, the inner aperture of the rubber embedded pipe 6 is slightly smaller than the outer diameter of the cable insulation layer 3, and tight fit and air tightness are ensured during cable connection.
The outer end part of the rubber embedded pipe 6 is provided with an air pipe joint 7, the air pipe joint 7 is a conventional standard joint and is in threaded connection with the rubber embedded pipe 6, and an O-shaped sealing ring is arranged on the outer diameter of the air pipe joint, so that the air leakage at the joint is ensured. The size of the air pipe joint 7 can be selected according to the size of a pipeline of an external air cooling device, and the air pipe joint is convenient to obtain and low in cost.
And (3) assembling the integral structure: firstly, the insulating layer 3 of the cable is stripped by a section (about 50mm), the conductor 2 is penetrated into the metal sleeve 4, and the conductor 2 and the metal sleeve 4 are pressed and connected by adopting a hydraulic cold welding technology. The metal sleeve 4 is internally provided with a rubber embedded pipe 6 which is in interference fit with the rubber embedded pipe, and the rubber embedded pipe are adhered by additional glue to ensure sealing. The outer side of the rubber embedded pipe 6 is provided with a gas pipe joint 7. The air pipe joint 7 is connected with the cooling air generator, external cooling air is transmitted to the inside of the air-cooling cable through the external cooling air generator, the flowing of the cooling air takes away the internal temperature of the conductor 2, the temperature of the conductor 2 is guaranteed to be in a normal state, and the current-carrying capacity of the conductor 2 can be greatly increased.
