Problems solved by technology

This is because the existing water-cooled cable has an inherent angle due to its own weight and its own installation plane, making it difficult for the installation bolts to fasten the cable plane and the connector plane to the pry
[0004] 2. The existing water-cooled cable cannot rotate with it when the large current is jittering, which will easily cause the inner core of the cable to be sprained and the outer sleeve to be broken

Embodiment Construction

[0019] The present invention is further elaborated below in conjunction with preferred embodiment:

[0020] Such as figure 1 with figure 2 As shown, the rotatable water-cooled cable of the present invention includes copper joint 1, pipe ferrule 2, copper strand 3, sealing ring 5, 11, ball 6, rotating sleeve 7, rubber tube 8 and differential spring 9, Among them: the ball 6 is embedded in the rolling groove on the outer edge of the copper joint 1, and then the grooved screw 12 is used to limit the position in the groove, and the rotating sleeve 7 is set on the outer edge of the cylindrical part of the copper joint 1 through the ball 6; the sealing ring 5 , 11 are located between the groove of the copper joint 1 and the rotating sleeve 7, the differential spring 9 is located at the center of the multi-strand copper strand 3, so that the copper strand 3 is wound along its outer edge, and the copper strand 3 is inserted into the copper joint 1 interface 4 inside. The outer edg...

Abstract

The invention discloses a rotatable water-cooled cable which comprises a copper joint, a copper stranded wire, a sealing ring, a roll ball, a rotary sheath and a differential spring; the roll ball is embedded in a rolling groove on the periphery of the copper joint and fixed by a bolt with a groove; the rotary sheath is sheathed on the periphery of a cylindrical part of the copper joint through the roll ball; the sealing ring is arranged between the groove of the copper joint and the rotary sheath; the differential spring is arranged in the center of multiple strands of copper stranded wires so that the copper stranded wires can be wound along the periphery of the differential spring and inserted into the interface of the copper joint. The periphery of the rotary sheath can be sheathed with a rubber tube for protection. The rotatable water-cooled cable has good cooling effect and can rotate with jittering high current, thus preventing the electrodynamic force from wrenching cable inner cores and the breakage of an outer sheathing tube, prolonging the service life of the cable and having simple installation and processing.

Description

technical field [0001] The invention relates to the field of electric power transmission of metallurgical electric furnaces, in particular to a rotatable water-cooled cable, which is a cluster type large-section water-cooled cable mainly used for transmitting large currents in metallurgical and steelmaking furnaces. Background technique [0002] The existing bundled large-section water-cooled cables have the following disadvantages: [0003] 1. The existing water-cooled cables are cumbersome to process and install. This is because the existing water-cooled cable has an inherent angle due to its own weight and its own installation plane, making it difficult for the installation bolts to fasten the cable plane and the connector plane to the pry [0004] 2. The existing water-cooled cable cannot rotate with it when the large current shakes, which may easily cause the inner core of the cable to be sprained and the outer sleeve to be broken. Contents of the invention [0005]...
