Description

High temperature resistant frequency conversion flexible cable
Technical field
The utility model relates to a kind of flexible cable, particularly a kind of high temperature resistant frequency conversion flexible cable.
Background technology
The AC converter speed adjusting technique is the important development direction of Modern Electrical Drive technology, and frequency converter is in the outstanding advantage of aspects such as performance, efficient, operability.As the converter cable of AC variable-frequency speed regulation system core,, not only in traditional electric drive system, obtained using widely, and almost expanded to industrial all spectra along with the development of this technology.The frequency-changing cable heat-resisting ability of prior art is relatively poor, meets fire and promptly fires, and water is being arranged or having under the complex environment of oil, the damage that is easy to be corroded, the normal electric breakdown phenomena that therefore takes place.
The utility model content
The purpose of this utility model is that a kind of high temperature resistant frequency conversion flexible cable will be provided, and the frequency-changing cable heat-resisting ability that efficiently solves prior art is relatively poor, perishable, and problems such as electrical breakdown often take place.The utility model relates to a kind of high temperature resistant frequency conversion flexible cable, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core, silicone rubber insulation layer, copper strips screen from inside to outside, described cable outer layer inside is followed successively by oxygen barrier layer twining package tape, copper wire copper strips combination screen and silicone rubber jacket from inside to outside, is provided with fire-retardant filler in the gap between cable inner core and cable outer layer.The number of the cable inner core in the described cable outer layer is one or more.The number of the copper strips screen in the described cable outer layer is one or more.Described conductor wire core is strand many conductor monofilament together.The material of described conductor wire core is the high purity oxygen free copper bar.Described oxygen barrier layer twining package tape is that the described copper wire copper strips combination of refractory synthetic mica tape screen is made up of the some soft round copper wires copper strips outer with wrapping in copper wire.The utility model cost is low, and energy consumption is little, and capacity is big, and speed adjustable range is big, has the characteristic of permanent power, permanent rotating speed, and is easy to use.The utility model still can keep the normal safe operation of certain hour under high temperature, humidity, environment, and the amount of being fuming is low, nontoxic, Halogen, excellent electrical properties has good cold resistance, thermal endurance, anti-interference, effectively guarantees the energising of current supply circuit safety, production, work can normally be carried out, effectively avoid cable in high temperature, high pressure, oil-containing and moisture condition, to be subjected to after the erosion of multiple abominable factor electric breakdown phenomena taking place.The utility model can be widely used in the frequency conversion speed-adjusting system in the intensive places of equipment such as skyscraper, hospital, mine, metallurgy, boats and ships, information industry, power station, subway, tunnel, petrochemical industry, particularly can be used as electric energy transmitting and signal transmission safety cable under high temperature, high pressure, oil-containing and moisture particular surroundings.
Description of drawings
Accompanying drawing 1 is a cross-sectional view of the present utility model.
Embodiment
Comprise the cable inner core among the figure and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core 1, silicone rubber insulation layer 2, copper strips screen 3 from inside to outside, described cable outer layer inside is followed successively by oxygen barrier layer twining package tape 5, copper wire copper strips combination screen 6 and silicone rubber jacket 7 from inside to outside, is provided with fire-retardant filler 4 in the gap between cable inner core and cable outer layer.
The number of the cable inner core in the described cable outer layer is one or more, preferred three thick three thin six roots of sensation cable inner cores, and the cross-sectional area of each cable inner core is 4-500mm 2
Described conductor wire core is strand many conductor monofilament together.The material of described conductor wire core is the high purity oxygen free copper bar.The conductor monofilament is through the naked round annealed copper wire after softening and the soft single line of round copper of electroplating surfaces with tin.The cross section of conductive monofilament is circular, and its sectional area is 0.5~4mm 2, the physical strength height of conductor wire core, mechanical performance is strong, good stability, its shape is constant, but very little to the curvature influence of cable.Conductor wire core is surrounded by silicone rubber insulation layer and copper strips screen outward successively, and copper strips screen herein is a conductor screen.Screen can reduce eddy current loss, can impel the electromagnetic wave boundary reflection, can also offset part and disturb electromagnetic wave, has the good effect that promptly absorbs energy, reflected energy and counteracting energy, thereby guarantees jamproof effect.
Described refractory filler is the glass rope, and this is a kind of non-hygroscopic filler, both can be high temperature resistant, can guarantee the rounding full weight of whole cable again.
Described oxygen barrier layer twining package tape is a refractory synthetic mica tape, and flame retardant coating surrounds outside the conductor wire core, is wrapped the forming of high-quality mica tape with fire-resistant safety cable special use, good fire resistant flame retardant effect is arranged, and still can keep good dielectric strength under ignition temperature.
Described copper wire copper strips combination screen is made up of the some soft round copper wires copper strips outer with wrapping in copper wire, and soft round copper wire closely wraps on the outer wall of inner covering, and copper strips wraps in copper wire and also oppositely tightens outward.The number of soft round copper wire can dispose in proportion according to the conductor wire core cross-sectional sizes.The shielded type cable of this structure can anti-electromagnetic induction; imperfect earth and power line conduction interference; reduce puncture or damage that inductance avoids powerful big thunder and lightning magnetic effect voltage to be caused; prevent characteristics such as induced electromotive force is excessive; copper wire copper strips combination screen had both played the externally effect of emission of electromagnetic wave that suppresses; can be used as the passage of short circuit current again, can play the protective effect of neutral core.Conductor shield is used with the combination screen and has formed totally-enclosed metal level, can effectively suppress electromagnetic interference.
Silicone rubber insulation layer and silicone rubber jacket all are to have thermoplasticity silicone rubber for cable material to make, and that this material has is high temperature resistant, low temperature resistant, oil resistant, plurality of advantages such as corrosion-resistant.The utility model can be in-60 ℃-180 ℃ scope operate as normal.
