Description
Technical field
The present invention relates to a kind of intermediate frequency induction heating power supply water power cable.
Background technology
Current portable intermediate frequency induction heating power supply can adopt hand-held transformer, can form high voltage (generally between 1000V to 2500V) and large output current in the water power cable between hand-held transformer inputs and host output end.Under normal conditions, water power cable adopts the HTHP wire of high-temperature-resistant high-pressure-resistant as carrying object.In water pipe, pass into cooling water cool wire.But this method has a maximum shortcoming to be: because the existence of wire insulation crust can increase the thermal resistance between wire and water, cause heat transfer smooth, thus reduce the effect of water-cooled, there is the possibility of wire fusing.Wire insulation crust is also easily damaged simultaneously, and insulation sheath is once breakage also can cause hand-held transformer charged, even scaling loss machine.
Medium frequency heating power source is operated in higher frequency, and power is comparatively large, is connected with high frequency heavy current in medium frequency heating power source water power cable.The high frequency heavy current of water power cable, produces extremely strong magnetic field, and under the effect of high-intensity magnetic field, electric current trends towards the surface of transmission medium.Adopt common copper cable to make the surface delivery of electric current along water power cable of the water power cable caused, reduce effective conductive area of water power cable, thus the resistance that result in water power cable increases, inductance lowers, and is unfavorable for the transmission of high power strong electric current.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of use safety, the intermediate frequency induction heating power supply water power cable that heat waste is little.
The present invention is achieved by the following measures:
The anti-creeping water power cable of a kind of intermediate frequency induction heating power supply of the present invention, comprises a backwater
Pipe and two outlet pipes, described return pipe is connected hand-held transformer case with outlet pipe one end, the other end connects collecting pipe, wire is provided with in two outlet pipes, described wire connects the coil of hand-held transformer, described outlet pipe is connected with the separate type copper sleeve of hollow, described separate type copper sleeve is connected with collecting pipe by pipeline, wire one end is by crossover sub connecting coil lead-out wire, the wire other end connects separate type copper sleeve, the external intermediate frequency induction heating power supply of separate type copper sleeve, described wire is some strands of enamel-cover copper stranded conductors.
Above-mentioned hand-held transformer case and the equal ground connection of collecting pipe.
The invention has the beneficial effects as follows:
Enamel-cover copper stranded conductor is applied in water-cooled cable, due to can not galvanic circle be formed between adjacent copper, effectively can suppresses kelvin effect, be conducive to the longitudinal direction transmission of electric current.The solid bare copper wire of multiply enamel-cover copper stranded conductor structural rate is more soft, and surface area is larger, has good heat dispersion.Meanwhile, multiply enamel-cover copper stranded conductor is because inner materials is not direct and extraneous contact, and rotproofness is strong, and long service life, increases the useful life of water-cooled cable.Enamel-cover copper stranded conductor pliability is better, convenient mobile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 hand-held transformer case, 2 outlet pipes, 3 lead-out wires of coil, 4 crossover subs, 5 return pipes, 6 wires, 7 separate type copper sleeves, 8 collecting pipes.
Embodiment
As shown in Figure 1, the anti-creeping water power cable of a kind of intermediate frequency induction heating power supply of the present invention,
Comprise a return pipe 5 and two outlet pipes 2, described return pipe 5 is connected hand-held transformer case 1 with outlet pipe 2 one end, the other end connects collecting pipe 8, wire 6 is provided with in two outlet pipes 2, wire 6 connects the coil of hand-held transformer, outlet pipe 2 is connected with the separate type copper sleeve 7 of hollow, separate type copper sleeve 7 is connected with collecting pipe 8 by pipeline, wire 6 one end is by crossover sub 4 connecting coil lead-out wire 3, wire 6 other end connects separate type copper sleeve 7, the external intermediate frequency induction heating power supply of separate type copper sleeve 7, wire 6 is some strands of enamel-cover copper stranded conductors.Hand-held transformer case 1 and collecting pipe 8 all ground connection.
The water of collecting pipe 8 flows into outlet pipe 2, is cooled by the wire 6 in outlet pipe 2, then flows in hand-held transformer, finally flow back into collecting pipe 8 from return pipe 5.
Wire 6 in the present invention adopts some strands of enamel-cover copper stranded conductors, thus replaces common copper cable, just effectively can suppress kelvin effect, improves the current transmission characteristic of water power cable.The uniform stranded formation enamel-cover copper stranded conductor of multiply very fine enameled wire, transverse current is not had between the multiply enamelled wire of composition enamel-cover copper stranded conductor, electric current transmits along enamelled wire, this is just equivalent to the effective conductive area that improve water power cable, reduce the resistance of water power cable, so effectively kelvin effect can be suppressed.This provides for improved the high-frequency current transmission characteristic of water power cable.The electric current that the fractional unit sectional area connecting hand-held transformer and water power cable passes through is maximum, and connect the front end of hand-held transformation, voltage change range is larger, connecting line herein also will suppress kelvin effect as much as possible, and connecting line wants high pressure resistant and high temperature, so connecting line herein must be HTHP line.
The above is only the preferred implementation of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection range that also should be considered as this patent.
