Abstract
A water-cooled cable for high-current transmission and distribution features that a group of multipurpose joints are fixed to both ends of cable sleeve by binding bands, and the wire bundles supported by elastic supporter are fixed to the middle of said multipurpose joints by inserting holes on said multipurpose joints. Thus effectively suppressing electromagnetic vibration, preventing abrasion between lines, reducing impedance, balancing three-phase power of the lines and prolonging the service life of the lines and the furnace shell.
Description
The utility model relates to the water-cooled cable that the big electric current of a kind of transmission ﹠ distribution is used, particularly at the cable that uses on the smelting metal smelting furnace.
At present, metallurgical arc furnace, ladle refining furnace, the short net flexible cable that power frequency induction furnace and big capacity induction furnace thereof use between transformer and stove adopts the single multiply flexible cable of dry type to send more, because of it carries big alternating current, make cable produce powerful magnetic and shake, the normal generation clashed into and rubbed between strand, particularly under the less situation in unit cable cross section, the reactance fluctuation is serious, voltage instability, three-phase current unbalance, stove internal power are difficult to control, heat up in the stove slowly to making, the duration of heat is long, and production efficiency descends, and add when high-power, also can have a strong impact on furnace shell useful life, real is not ideal, the disadvantage when sending electricity in order to overcome single multiply flexible cable, and it is the water-cooled cable of water flowing skeleton with the sebific duct that people once developed a kind of, but because of cooling effect does not reach requirement, the line impedance imbalance happens occasionally.
In order to overcome above-mentioned disadvantage, the utility model provides a kind of can prevent electric and magnetic oscillation, prevents to wear and tear between the strand, improves circuit useful life, reduces impedance, makes its three-phase power balance, increases the furnace shell water-cooled cable in useful life.
To achieve these goals, way of the present utility model is on the basis of existing Water cooling cable, in the two ends of cable sleeve 5, fix one group of multipurpose joint 3 by the power of tightening of band B, the centre firmly is connected with the bundle conductor 6 that is supported by elastic shelf 4 by the cable jack D on the multipurpose joint 3, with also be provided with hydraulic signal device 10, water temperature signal device 11 on the water pipe 9 that multipurpose joint 3 links to each other.
For water-cooled cable externally is connected with equipment is convenient, internally convenient water supply connects bundle conductor, overcomes eddy current loss, multipurpose joint 3 has adopted non-magnetic metal or nonmetallic materials to make, on its coaxial direction, be provided with discharge orifice E, seat hole F, a plurality of cable jack D, screw G reaches with this perpendicular direction and is provided with installing hole A, and hoisting ring 1 is equipped with in its screw G in the mouth of a river 2.
For each the root lead X cooling effect that makes the bundle conductor of being made up of many lead X 6 improves, overcome between strand the magnetic shake and waste wiping, every lead X establishes an anti-vibration sleeve 7 every a segment distance along its length, and detour its whole story according to the helical mode along the less elastic shelf 4 of resistance to water-flow, insert among each cable jack D of special joint 3 one by one the termination of every lead X, by mechanical means it is fixed simultaneously.
In order to make the water-cooled cable good cooling results, long service life, folding stress is little, and its elastic shelf 4 has been used non-magnetic conduction, and the corrosion resisting elastic material is made a kind of flexible type structure, and two ends are set among the seat hole F of multipurpose joint 3.
For making the controlled and supervision of water-cooled cable water supply situation, on the outlet pipe section of cooling water, hydraulic signal device 10 is housed, water temperature signal device 11, this kind senser can be selected commercially available Pressure gauge and thermometer respectively for use, particularly selects for use the table that has controlled function even more ideal.
In view of above-mentioned way, a kind of satisfy under big current conditions working, realize that the utility model purpose water-cooled cable just can implement to be expected to.
The utility model will be illustrated before will advancing one by an embodiment:
The explanation of accompanying drawing drawing:
Fig. 1 is the water-cooled cable structural representation
1 hoisting ring among the figure, 2 mouths of a river, 3 multipurpose joints, 4 elastic shelfs, 5 cable sleeves, 6 bundle conductors, 7 anti-vibration tubes, 8 vibrationproof circles, 9 water pipes, 10 hydraulic signal devices, 11 water temperature signal devices, the A installing hole, B pricks hole, E discharge orifice, hole, Building F, G screw, X lead.
Fig. 2 is a water-cooled cable C-C sectional schematic diagram
The utility model, requirement according to dissimilar metallurgical furnaces, according to the utility model principle, can be made into the product of 16 kinds of specifications of conductor cross-section 120 mm sq to 600 mm sq meters, they all select non-magnet material for use, do multipurpose plug by cold working or running casting legal system, according to the live load difference, its mouth of a river, the discharge orifice can be made into the hole that 1/2 inch to 1 inch varies in size, in like manner, with 3 to 13 varying numbers lead along elastic shelf coiled spirally, leave 0.5 to 3 millimeter gap between each lead, insert in the cable jack its termination, and it is fixed with extrusion process, and cable conduct adopts anti-thermal-enhanced sebific duct and by certain pressure it is enclosed within on the bundle conductor, and it is tightened by band in the multipurpose joint connection place in order to prevent to leak, when work, only need the installing hole at two ends is connected with equipment, electricity is sent in normal water flowing, gets final product work.
The utility model has following technological progress compared to existing technology:
Thereby 1, because every wire sleeve of bundle conductor has shockproof sleeve pipe that water-cooled cable can be hindered and faces upward powerful electric current magnetic vibration, overcome and run foul of each other and wear and tear, cable life is significantly improved.
2, because bundle conductor adopts the electric wire of limited quantity to turn to spirally, make this water-cooled cable reactance little, it is poor to fluctuate, three-phase current is in a basic balance, and power output is easy to control, when particularly exporting big electric current, heat radiation effect to stove weakens, and makes the furnace shell Service life.
3, because bundle conductor personal share lead keeps a determining deviation, distribute rationally, so CURRENT DISTRIBUTION is even in the water-cooled cable, current can be led to everywhere, good cooling results, and current density improves, thereby can save metal material consumption.
4, owing in water supply line, be provided with hydraulic pressure, water temperature signal device, can in time grasp the working condition of cable like this, in order to can realize hydraulic pressure. Water temperature is controlled purpose automatically.
