Abstract
A large cross-section coaxial water-cooled cable for metallurgic electric furnace disposes positive electric conductor and inner water-cooled casing pipe between two positive cable head. Two negative cable head are arranged on the two terminals of the pipe. A negative electric conductor and external water-cooled pipe are disposed between the two negative cable head. Cable head outer coating is disposed on the positive cable head. Leak proof protecting casing pipe is disposed between the cable head outer coating and the negative cable head. The negative cable head is a global hollow cylinder with different external diameter which is made up of integral material. That power receiving arm is disposed on the body and cold pressed connection between each cable head and electric conductor composes coaxial structure. The utility model has the advantages of energy saving, no leakage, no vibration, long service life, convenient installation and low cost.
Description
Affiliated technical field
The utility model relates to a kind of water-cooled cable, especially about the coaxial water-cooled cable in the heavy in section of using on the metallurgical electric furnace.
Background technology
A few days ago, known water-cooled cable is a branch of electric conductor of soldering between two positive electrical cable ends, water cold sleeve that is used for its cooling of socket, negative electricity cable end of this pipe each suit of two ends, the a branch of electric conductor of soldering between two negative electricity cable ends, one of socket is used for the outer water cold sleeve to its cooling, the negative electricity cable end is away from the outer water collar pipe end of socket, connect a seal ring that is used for leakproof, wherein the negative electricity cable end is made type by copper pipe and the compound weldering of stainless steel tube that is located at the outside, the water-cooled cable of this structure often runs in using: the negative electricity cable end that is welded with stainless steel casing, copperhead and stainless steel tube sealing-off, adhesion descends, electric conductor water collar internal strain outside, the seal ring sealing effectiveness is poor, easily sends out seepage; Air chamber or air gap take place in the soldering structure of each cable end and electric conductor in the combination of being everlasting, cause both contact resistances to increase, the cable end heating, and reactive loss increases, and threatens safe operation, and is desirable not to the utmost.
Summary of the invention
In order to overcome existing water-cooled cable weak point, the utility model provides a kind of heavy in section coaxial water-cooled cable, and this cable can reduce the contact resistance of cable end and electric conductor effectively; be provided with the protection against leakage sleeve pipe between the positive and negative electrode cable end; safe and reliable to operation, energy-saving and water-saving, production cost is low.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with cathode conductor and to the interior water cold sleeve of its cooling between two positive electrical cable ends; these pipe two ends are respectively equipped with cover negative electricity cable end thereon; be provided with the negative pole electric conductor between two negative electricity cable ends and to the outer water cold sleeve of its cooling; the positive electrical cable end is provided with the cable end overcoat; be provided with the protection against leakage sleeve pipe between this cover and the negative electricity cable end; the negative electricity cable end is that an integral material is made different being used for of external diameter and connected; support electric conductor; outer water cold sleeve; the whole hollow cylinder of the multistage of protection against leakage cover; body is provided with the electric arm that is subjected to that links to each other with power supply, and each cable end is colded pressing with electric conductor and is connected.
The beneficial effects of the utility model are: each cable end is connected resistance less than 0.017 Ω/m.mm with electric conductor
2, the water-cooling system good airproof performance, electric conductor magnetic flux density is little, and electric conductor operation amplitude is faint, energy-saving and water-saving, compact conformation is saved the space, and long service life is easy for installation, reduces production costs.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified
Fig. 1 is the utility model vertical section structure schematic diagram
1 positive electrical cable end, 2 protection against leakage sleeve pipes, 3 negative electricity cable ends, 4 outer water cold sleeves, 5 interior water cold sleeves, 6 are subjected to electric arm, 7 negative pole electric conductors, 8 cathode conductors, 9 to be subjected to electric arm installing hole, 10 cable end overcoats, 11 cable end overcoat installing holes among the figure
Embodiment
The utility model is to be provided with cathode conductor (8) and to the interior water cold sleeve (5) of its cooling between two positive electrical cable ends (1) as seen from the figure; these pipe two ends are respectively equipped with cover negative electricity cable end (3) thereon; be provided with negative pole electric conductor (7) between two negative electricity cable ends (3) and to the outer water cold sleeve (4) of its cooling; positive electrical cable end (1) is provided with cable end overcoat (10); be provided with protection against leakage sleeve pipe (2) between this cover and negative electricity cable end (3) other end; negative electricity cable end (3) is that an integral material is made different being used for of external diameter and connected; support electric conductor; outer water cold sleeve; the whole hollow cylinder of the multistage of protection against leakage cover, body be provided with link to each other with power supply be subjected to electric arm (6).In order to reduce magnetic induction, saves energy is saved the space, increases cable end and electric conductor bonding strength, reduces contact resistance, and positive and negative electrode water-cooled cable group is a coaxial structure, and each cable end is colded pressing with electric conductor and is connected.
