Description
The utility model relates to the water-cooled cable that the big electric current of a kind of transmission ﹠ distribution is used, and relates to the flexible AC water-cooled cable that uses on the equipment such as arc furnace, power frequency induction furnace, ladle furnace and big capacity induction melting furnace specifically.
In big electric current power transmission and distribution were flexible coupling, water-cooled cable was characteristics with its high efficiency and heat radiation cooling, and widespread usage is on equipment such as arc furnace, power frequency induction furnace, ladle furnace and big capacity induction melting furnace.Water-cooled cable is according to using current characteristics to be divided into to exchange two kinds of water-cooled cable and direct current water-cooled cables.In the prior art, exchange water-cooled cable and mainly form by bundle conductor, inner sleeve, two connector lugs, outer tube and sheath circles.Inner sleeve coats the multi-layer conductor leads bundle as spiral on its outer rim of central support, constitutes hollow cellular conductor with this and assembles conductor construction.Two connector lugs adopt hydraulic press to press connection to dock from two ends and lead aggregation respectively.Outer tube is enclosed within the lead aggregation and forms insulating barrier outward, and outer tube is fixed on the connector lug by clamping ring, forms closed structure, and the sheath circle is enclosed within outer tube again and forms the protection structure outward.Connector lug is provided with the center water channel, and butt joint rear center's water channel and lead aggregation and outer tube constitute inside and outside double-deck cooling-water duct.More than exchange the water-cooled cable good cooling results, electric conductivity is good, long service life, but also have following hidden danger and deficiency in the practice: temperature is very high during 1, owing to cable work, in case the cable circulate cooling water inside stops, the hurried rising of cable temperature meeting is if handle untimely, the lighter damages equipment, and weight person causes fire incident.2, because connector lug adopts disposable pressure connection to be connected with bundle conductor, and after wearing out as the generation inner sleeve, fragment stops up cooling-water duct, can't dismantle, and promptly can not repair, and can only change, in fact this caused very big waste.
The utility model purpose provides a kind ofly has the water cut-off protection function, and repair demolition direct current water-cooled cable easily.
For achieving the above object, the technical solution adopted in the utility model is: a kind of interchange water-cooled cable, comprise bundle conductor, inner sleeve, the connector lug of a pair of band water channel and insulating coating pipe, inner sleeve constitutes the cellular conductor aggregation as its outer rim spiral coated wire bundle of central support, the insulating coating pipe be the gap to be enclosed within the lead aggregation outer and become hermetically-sealed construction, a pair of connector lug docks with the lead aggregation from two ends respectively, wherein the water channel in the connector lug constitutes cooling-water duct with the central passage of lead aggregation and peripheral channel respectively, and pricker is melted in the bundle conductor perfusion in connector lug and the lead aggregation or molten soldering connects.
In the technique scheme, described " bundle conductor " is meant the collective that is made up of many leads.Described " inner sleeve is as its outer rim spiral coated wire bundle of central support " is meant that several leads are wrapped on the inner sleeve from inside to outside layer by layer with the hank knotting shape.Described " butt joint " has two-layer connotation, first cooling-water duct butt joint, and it two is connector lugs and being electrically connected of bundle conductor.It contains described " molten pricker of perfusion or molten soldering connect " and mean: 1, connected mode is welding; 2, adopt the low melting point welding material, as pricker, tin, pricker alloy, ashbury metal or other; 3, because bundle conductor is formed by many, impossible one one welding can only be the welding of many leads and connector lug globality.
In order to make the better of bundle conductor welding in connector lug and the lead aggregation, the butt joint end face of the described connector lug of technique scheme is provided with the butt joint chamber, the lead aggregation stretches in the butt joint chamber, and molten pricker or the infiltration of molten tin form integral body and be connected in the slit of butt joint chamber and lead aggregation.
In the technique scheme, when being connect, molten pricker of bundle conductor perfusion in connector lug and the lead aggregation or molten soldering be unlikely the obstruction water channel, this programme is provided with an adapter in described butt joint chamber central authorities, takes over to extend to outside the butt joint chamber, and the root of adapter [3] is threaded with the watercourse port on the connector lug.Simultaneously, because inner sleeve is an insulation rubber tube, cooling water can't be penetrated in the bundle conductor by wall and cool off, in order to guarantee cooling effect, the inner sleeve mouth of pipe is fixed a circle and is parallel to tube wall and spaced apart barred body, bundle conductor stretches into the butt joint chamber during butt joint, inner sleeve rides over by the barred body that extends and takes on the outer rim, make cooling water be divided into two-way, the inner sleeve of leading up to cools off bundle conductor indirectly, and bundle conductor is directly cooled off by the circular passage that the space that is barricaded as between barred body flows between inner sleeve and the outer tube in another road.
The utility model operation principle is: utilize low-melting pricker or tin as welding material, and integral solder connector lug and bundle conductor junction, weld fusing after cable temperature raises, the lead aggregation comes off under the effect of gravity automatically, cuts off the electricity supply.When dismantling, needs, just can be easy to open as long as heating makes the weld fusing.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because pricker is melted in the perfusion of the bundle conductor in the utility model connector lug and the lead aggregation or molten soldering connects; after the recirculated cooling water cutout; along with cable temperature rises; pricker or tin solder are heated and melt automatically; the lead aggregation comes off under the effect of gravity automatically; initiatively cut off the electricity supply, not only protect equipment but also can avoid serious accident to take place.
2, because molten pricker of the perfusion of the bundle conductor in the utility model connector lug and the lead aggregation or molten soldering connect, in case inner sleeve is aging, fragment can melt weld after stopping up cooling-water duct, dismounting is changed then, needn't cause waste.
3, because molten pricker of the perfusion of the bundle conductor in the utility model connector lug and the lead aggregation or molten soldering connect, compared with prior art reduce resistance, increased conductivity.
