Description
Technical field
The present invention is a kind of enamelled-wire cable, specifically the immersion type enamelled-wire cable used of the high-power hand-held Transformer Winding of a kind of medium-high frequency electromagnetic induction heating.
Background technology
The high-power hand-held transformer that is used for the medium-high frequency electromagnetic induction heating in the prior art, adopt winding coil that the high-frequency high-voltage of power switch pipe output is changed into the high frequency low voltage electricity, winding coil is in the insulation of the outside sleeve thermoplastic of copper tube tube sealing, by to copper tube knee differential annealing, make the copper tube deliquescing.In winding coil when work, by the entery and delivery port of main coil and secondary coil, pass into primary and secondary coil by the copper tube coiled with the deionization cooling water, takes away the heat that high-power hand-hold type Transformer Winding coil internal work produces.
Because the operational characteristic of copper tube when the high-power hand-hold type Transformer Winding of coiling coil, the coil turn that has determined coiling can not be many, so, have influence on the more powerful hand-held transformer of exploitation, secondly, because the skin effect of current flowing, more powerful hand-held transformer just needs the thicker copper tube of caliber with the requirement of the skin effect that satisfies larger current density and flow through thereon, also need simultaneously thicker pipe flow section, so that it is enough large to take away the flow of deionization cooling water of heat, in view of the foregoing, the volume of more high-power hand-held transformer is often larger, weight is also larger, the personnel that are unfavorable for field operation use for a long time, and when thicker metal heated, larger high-power transformer can only be installed in just can be used in the workplace on the relevant equipment, therefore, strengthened the input cost of equipment.
Summary of the invention
The object of the present invention is to provide a kind of immersion type enamelled-wire cable of using for the high-power hand-held Transformer Winding of medium-high frequency electromagnetic induction heating, simple in structure, sealing is reliable, lightweight, can be by large electric current, reliable operation, in the situation that be connected with the cooling deionized water, large electric current being transported to can not generate heat at a distance burns cable.
The technical solution used in the present invention is: left end of the present invention has water supply connector, right-hand member that the emerged wedge joint is arranged, the water supply connector right-hand member stretches in first copper tube left end centre bore and both interference fit, emerged wedge joint left end stretches in the water out adapter seat centre bore and with the water out adapter seat and is fixedly connected with, and water out adapter seat fixed cover is in second copper tube right-hand member centre bore and both interference fit; Very fine enameled wire bundle cable two ends are stretched into respectively in two copper tube centre bores and are connected, and the junction of two copper tubes and very fine enameled wire bundle cable is moulded to the shape that cross section is semicircle; At two copper tubes and very fine enameled wire bundle cable jacket a teflon sleeve is arranged, form the cooling water channel that passes through for the ion cooling water between very fine enameled wire bundle cable and the teflon sleeve; Between very fine enameled wire bundle cable left end in first copper tube centre bore and the water supply connector right-hand member one section space is arranged, have the water inlet that is communicated with water supply connector centre bore and cooling water channel on first red copper tube wall of this gap; Between very fine enameled wire bundle cable right-hand member in second copper tube centre bore and the water out adapter seat left end one section space is arranged, second red copper tube wall in this gap has the delivery port that is communicated with cooling water channel and water out adapter seat centre bore.
The present invention has the following advantages:
1, the deionization cooling water soaks superfine enamel-cover wire harness cable, can take away a large amount of work calorieses, therefore, so that can pass through larger electric current on it, and and weight increase, the wire diameter of cable are increased slightly; So the volume of the high-power hand-held transformer that twines with its can be done littlely, working temperature more powerful, shell is normal; Wire diameter is thin, lightweight, the working sites beyond being easy to twine, larger electric current can be transported to 100 meters.
2. the syndeton of the nipple that adopts of the present invention is so that the primary and secondary coil of high-power hand-held transformer is easy to dismounting, safeguards the good insulating of the used high-strength teflon sleeve of insulation, the life-span of having improved high-power hand-held transformer.Have the characteristics of dismantling, installing of being easy to, be fit to field work, and should not fracture and damaged.
3. the invention enables composite water to unite two into one, the copper sleeve at cable two ends is connected with the electrode of equipment by copper nut, axis at copper sleeve is opened the hole, pass into the deionization cooling water, form the outside energising of connector portions, the connected mode of middle water flowing, and at conducting line segment, under the sealing of the high-strength teflon sleeve sealant of insulation, middle very fine enameled wire is by larger electric current, the peripheral cooling deionized water that soaks is by fluid interchange, take away the electricity of heat, hot mode of movement, the through hole of water supply connector is slightly larger than the through hole of water out adapter, so that the deionization cooling water can carry out sufficient heat exchange with cable when flowing through the very fine enameled wire cable, the through-hole diameter of its delivery port is smaller, so that muzzle velocity and the pressure of the deionization cooling water of Transformer Winding coil or transmission cable all are improved, is convenient to the backflow of deionization cooling water in system.
