Abstract
The invention discloses a special vacuum water-cooled cable joint and a manufacturing method thereof. The connection mode of the cable joint and a flat copper wire adopts a pressure welding mode instead of a conventional end welding mode; a conventional joint sealing mode and a cable core material are changed; three arc-shaped bosses (1) are reserved on the cable joint to realize the seal in vacuum; the problem of cable core rupture at a joint is solved; and the working reliability of a water-cooled cable in the vacuum is enhanced. Because of a simple structure, a requirement on rapid manufacturing is met and import is substituted. An ideal intermediate/high-frequency power supply power transmission product is provided for vacuum induction melting.
Description
Technical field
The present invention relates to vacuum water-cooled cable joint manufacturing process, particularly special-purpose water-cooled cable joint of vacuum and manufacture method thereof.
Background technology
The water-cooled cable that vacuum induction melting furnace uses, the electric power that mainly is used in the high-power vacuum power supply between induction coil and the intermediate frequency power supply is carried, and is because condition of work is special, very strict to the quality requirements of water-cooled cable.At first, cable must be able to bear the above hydraulic pressure of 1.5MP.Owing to be to use under vacuum state, this cable joint must bear 1 * 10
-3The vacuum degree of pa guarantees that simultaneously no-cooling-water leaks.Secondly because cable is frequent crooked under vacuum state, cause cable breakdown easily, the part of cable fractures and directly causes the cable surface current density to increase, thereby quickens cable bad.Thereby, the necessary fatigue resistance that improves the vacuum water-cooled cable.
Existing cable conductor material adopts 0.5 millimeter copper cash braiding, 110 square millimeters of total sectional areas.Because cable is harder, the frequent bending in the work, the position, termination occurs the cable silk easily and fractures, after fracture of wire reaches some, along with the increase of surface current density causes the very fast inefficacy of cable.Preferably under the situation, be 1～2 year the useful life of cable joint, can only use during water quality inferiority 3～6 months in water quality.Because cable is one boss sealing, under high vacuum condition, uses to occur infiltration easily, thereby destroy vacuum, even occur freezing under the normal temperature.
Because existing vacuum water-cooled cable dependence on import, not only the time long, price height, and have many defectives.In view of this, the invention provides special-purpose water-cooled cable joint of a kind of vacuum and manufacture method thereof.
Summary of the invention
(1) technical problem that will solve
For solving the problems of the technologies described above, the object of the present invention is to provide a kind of vacuum precision casting specific power cable design and manufacture method thereof, solve water-cooled cable and bear pressure differential, technical problems such as useful life is short, effectively guarantee the water flowing of cable joint and the fatigue resistance of cable joint and cable connecting part position, improve vacuum seal structure, prevent the cooling water seepage.
(2) technical scheme
For solving the problems of the technologies described above, the present invention is achieved through the following technical solutions:
1, cable design:
(1), at first designs this cable joint at above-mentioned technical problem.The cable core material is designed to the multiply flat type copper wire, 90 square millimeters of total sectional areas, flat copper filament footpath 0.15～0.3mm.Guaranteeing that under the good situation of conduction, quality is soft as far as possible, to improve fatigue resistance.According to the skin effect theory, skin depth and frequency are inversely proportional to, and during high frequency, the thickness of the cross section of electric current process approximates skin depth in the copper conductor.Therefore, can there be bigger carrying load ability in identical cross section.
(2) on the connected mode of cable joint and flat type copper wire, change traditional termination welding manner into the crimping mode, to solve the problem of flat type copper wire and cable joint connecting portion anti-fatigue ability difference;
(3) cable joint material selection oxygen-free copper uses under vacuum condition guaranteeing;
(4) on cable joint aspect the structural design, be provided with three road circular arc boss, 18～20 millimeters at interval of boss, height of projection is 1.5 millimeters, has so just formed the two seals groove.By the elastic shrinkage of sebific duct, realize sealing substantially;
(5) in the position of the outside circular arc boss 1 of sebific duct, design has the twice clip, realizes sealing for the second time.For guaranteeing that vacuum hose and three boss combine closely, its monolateral magnitude of interference must not be less than 1 millimeter.Under the long-term work condition, after the first road seal failure, follow-up sealing still can play a role.Guaranteed the job stability of vacuum water-cooled cable;
(6) do not generate heat for guarantee that clip is worked under the high-intensity magnetic field condition, the austenitic stainless steel 1Gr18Ni9Ti that clip material selection thickness is 0.8～1.2 millimeter, the clip set bolt is M6.
(7) sectional area of cable sebific duct is 1.5 times of flat copper cable, to satisfy enough water passing capacities that cable has.
2, cables manufacturing:
Cable joint and cable core adopt the direct crimping mode of copper pipe, on technology copper ring are cut 1/2nd along diametric(al), treat that cable core inserts the back and with screw pressure device cable core and joint compressed.Because position, termination cable has certain flexibility, has solved FATIGUE FRACTURE PROBLEMS.
In addition, consider reasons in structure, the joint sealing conical surface is suppressed later on putting sebific duct; Because joint and sebific duct are in penetrating process, seal boss and pipe friction are very big to be difficult for being inserted in, and has made special-purpose two class instruments and solve in this process.The formation that sealing cone rises mouthful is placed on last procedure, utilizes the copper rod extruding to finish on engine lathe.
(3) beneficial effect
Compared with prior art, beneficial effect of the present invention is as follows:
The present invention's " special-purpose water-cooled cable joint of vacuum and manufacture method thereof " owing to changed traditional joint sealing mode and pulled core material, has realized the vacuum lower seal, has solved the joint and has pulled the core breakage problem.Satisfy the quick manufacturing requirement because of simple in structure, substituted import.For vacuum induction melting provides a kind of desirable middle and high frequency power electric power conveying products.
