Description

Technical Field

[0001] The utility model relates to the field of metallurgical equipment, in particular to a protective device for water-cooled cables. Background Art

[0002] Water-cooled cable, as a specially designed cable, has the main feature of circulating coolant inside. This design enables it to effectively take away the heat inside the cable, thereby reducing the temperature of the cable. This feature makes water-cooled cables widely used in many equipment that requires high power and long-term operation.

[0003] Especially used in refining furnaces, but when the refining furnace is powered on and arcing, the current is unstable and the magnetic field generated is constantly changing, which will cause the water-cooling cable to swing. During the swing of the water-cooling cable, the distance between water-cooling cables of different phases is large, and the probability of collision and friction is small, while the distance between water-cooling cables of the same phase is small, which is very easy to cause contact and friction. In the long run, it will cause surface wear of the water-cooling cable and reduce the service life of the water-cooling cable. Therefore, it is necessary to protect the water-cooling cables of the same phase.

[0004] The traditional protection method is to add a rubber sleeve outside the water-cooling cable to prevent the water-cooling cable from direct collision and contact and reduce wear. However, it was found during use that the rubber sleeve itself was severely worn during the cable swing, and the water-cooling cable was still severely worn, so the traditional protection method was ineffective. Summary of the invention

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a protective device for a water-cooled cable, which can improve the protective effect of the water-cooled cable, reduce the wear of the water-cooled cable, and increase the service life of the water-cooled cable.

[0006] In order to achieve the above objectives, the utility model proposes the following technical solutions:

[0007] A protective device for a water-cooled cable comprises more than two rubber hoops and a rubber connector. A protruding ring body is provided on the outer wall of the rubber hoops. The provision of the protruding ring body is beneficial to protecting the rubber hoops and reducing losses. The rubber connector is provided between the rubber hoops to connect the rubber hoops as a whole. The number of the rubber hoops is consistent with the number of water-cooled cables in the same phase. The overall height of the rubber connector is not greater than the height of the rubber hoops.

[0008] Preferably, more than four protruding ring bodies are arranged on the outer wall of a rubber hoop, and the protruding ring bodies are kept parallel to each other. The upper surface of the uppermost protruding ring body among the protruding ring bodies is on the same horizontal plane as the upper surface of the rubber hoop, and the lower surface of the lowermost protruding ring body is on the same horizontal plane as the lower surface of the rubber hoop. In this way, the rubber hoop can be protected to the greatest extent, loss can be reduced, and protection time can be extended.

[0009] Preferably, the upper surfaces of the rubber sleeves are on the same horizontal plane, the height of the rubber connector is consistent with the height of the rubber sleeve, and the upper surface of the rubber connector and the upper surface of the rubber sleeve are on the same horizontal plane, which can increase the stability of the protection effect and thus improve the protection performance.

[0010] Preferably, both ends of the rubber connector are connected to the protruding rings on the rubber sleeve, and are not directly connected to the rubber sleeve, thereby reducing manufacturing difficulty and production cost.

[0011] Preferably, the rubber connector is a rubber spring having a certain elasticity, which can further absorb shock and vibration on the basis of driving the same-phase cables to move in the same direction, thereby improving the protection effect.

[0012] Preferably, the connection position between the rubber spring and the rubber hoop is between the protruding ring bodies.

[0013] Preferably, the protruding ring body is spirally distributed on the outer wall of the rubber sleeve, so as to further expand the protection surface on the basis of driving the in-phase cables to move in-phase.

[0014] When in use, the rubber hoop is put on the water-cooled cable of the same phase. When the cable shakes, the shaking amplitude is reduced through the interaction of the rubber connector to achieve a vibration reduction effect. At the same time, the cables of the same phase are driven to move in the same direction, reducing the mutual collision and friction between different cables of the same phase, reducing the wear of the rubber hoop itself, thereby improving the protection effect of the water-cooled cable and increasing the service life of the water-cooled cable.

[0015] The beneficial effects of the utility model are:

[0016] The utility model connects the rubber hoop into one body through the rubber connector, and sleeves the rubber hoop on the same-phase cable. Due to the connection of the rubber connector, the same-phase cable can shake in the same direction, which reduces the mutual collision and friction between different cables in the same phase, reduces the wear of the rubber hoop itself, and thus improves the protection effect of the water-cooled cable, reduces the wear of the water-cooled cable, and increases the service life of the water-cooled cable.

[0017] By adopting the above scheme, the utility model can improve the protection effect of the water-cooling cable, reduce the wear of the water-cooling cable, and increase the service life of the water-cooling cable. BRIEF DESCRIPTION OF THE DRAWINGS
