Description
Technical field
The utility model relates to a kind of cable, and especially a kind of high temperature resistant soft type medium-frequency water-cooling cable, belongs to cable technology field.
Background technology
Medium-frequency water-cooling cable is one of critical piece of medium-frequency electrical heating equipment, it is the tie of ditch energize and load, because Intermediate Frequency Induction Heating Equipment is low-voltage and high-current, caloric value is huge, therefore need to be by water as carrier, the heat of cable generation in service is taken away, improved the ampacity of cable.This type of cable can be divided into two classes according to application: plain edition and high temperature resistant type, but existing high temperature resistant type water-cooled cable environmental-protecting performance is poor, and bending property is not good.
Utility model content
The purpose of this utility model is by the analysis to intermediate frequency water-cooled cable environment for use and feature, cable conductor, structure and material are optimized and are improved, developed have that ampacity is large, good cooling results, Stability Analysis of Structures, the high temperature resistant soft type medium-frequency water-cooling cable of long service life.
The purpose of this utility model is achieved through the following technical solutions: high temperature resistant soft type medium-frequency water-cooling cable, comprise cable core, the armour arranging on cable core, it is characterized in that, on the flexible support pipe circumference of described cable core by carbon fiber composite high-molecular material, conductor being set equably forms, on cable core, be surrounded with high-strength nylon isolation band internal layer, polyester film isolation band is outer, on polyester film isolation band skin, connect and extrude by elastomeric material internal layer sheath, nylon folder cloth rubber belt braiding reinforced layer or nylon add unsintered tape braiding reinforced layer, the sebific duct sheath that neoprene outer jacket forms, on sebific duct sheath, be surrounded with the enviroment protective ceramic fabric strip insulating layer of high-temperature resistant grade, insulating layer is provided with the armour of nonmagnetic material, armour surface spraying has high-temperaure coating, described conductor, by through softening stranded the forming of enamelled wire of processing, is provided with the support isolation module of memory elasticity macromolecular material between adjacent conductor.
On described flexible support pipe, be provided with equably a plurality of apertures, its surface is provided with the composite bed that hardness is little.
Described support isolation module is provided with equally distributed tap hole.
The flexible support pipe that the utility model adopts the polymer composite of excellent performance to make, makes cable have rock-steady structure and good cooling effect.This stay pipe is that the composite high-molecular material that carbon fiber is strengthened is made, and has good mechanical strength, the elasticity that temperature resistant grade is suitable, simultaneously high temperature resistant hydrolysis etc. again.Adopt even loose structure, do not affect flowing of cable internal cooling water, surface adopts the little composite bed of hardness simultaneously, guarantees that the enamelled coating of cable conductor in flexion torsion process is not damaged, and guarantees cable structure stable under high-temperature condition.Traditional supporting-core pipe and the structural unstable shortcoming of centreless pipe type cable have been solved.
The utility model adopts that enamelled wire is stranded to be formed, and due to enamelled coating protection conductor corrosion resistance and good, is difficult for getting rusty, and has improved cable useful life.According to set of surfaces skin effect principle, the existence of enamelled coating makes electric current transmit along enamelled wire monofilament direction, improved effective transmission sectional area, reduced due to the heating energy quantity of heat production of common bare copper stranded wire cable due to surface transmission, the cable current capacity of equal sectional area is greatly enhanced.
General water-cooled cable directly twists strand on supporting-core pipe again, but between strand, because contact friction meeting causes surperficial enamelled coating, comes off in processing and use procedure, affects the useful life of cable.For above problem, cable according to the different cross-sections of cable adopts reasonably support isolation module, the feature of this module maximum is that density is little, hardness is little, good springiness, simultaneously have from down to up equally distributed tap hole, facilitate cable in use cooling water can be passed to smoothly inner each several part, do not affect the radiating effect of cable.Strand supports isolation module and adopts memory elasticity macromolecular material, is mainly to support each strand to be uniformly distributed, and keeps Stability Analysis of Structures.In use, when cable is reversed or stretches, avoid the phase mutual friction of cable strands, thereby reduce enamelled coating, come off, improve the useful life of cable.
Isolation band internal layer of the present utility model adopts wrapped the tightening of high-strength nylon band, guarantees the stable of conductor thread core structure; The outer polyester film that adopts of isolation band is wrapped, guarantees that sheath material does not penetrate in conductor strand in sheathing process.Intensity nylon isolation band internal layer, polyester film isolation band skin have formed isolation belting layer jointly.
Sebific duct sheath of the present utility model is containing internal layer sheath (double makeing insulated), reinforced layer, sheath skin, adopt reinforced sebific duct, internal layer sheath adopts good insulation preformance, water-fast and resistant to elevated temperatures specific rubber material, reinforced layer adopts nylon folder cloth rubber belt and braiding to strengthen, outer jacket adopts neoprene, guarantees electric property and the mechanical performance of cable simultaneously.Adopt man-hour series connection to extrude adding, disposable machine-shaping, has improved the compactness of each layer, guarantees electric property and the mechanical performance of sheath, has improved production efficiency and the product quality of cable.
Insulating layer adopts the enviroment protective ceramic fabric strip of high-temperature resistant grade wrapped, can protect cable gum to manage and protect the destruction that layer is not subject to environment for use high-temperature temperature.The tradition asbestos insulation material feature of environmental protection is poor, and the healthy serious harm to people, now orders and ban use of.This enviroment protective ceramic fabric strip heat insulation effect and temperature resistant grade can meet the requirement of this cable completely, simultaneously also as the cushion of flexible armoring layer.
Armour adopts nonmagnetic metal material processing to form, and according to concrete applied environment, can select different temperature resistant grade materials, meets high temperature resistant, the resistance to boiling hot requirement of spattering.And in flexible armoring surface spraying special high temperature-resistant coating, improve surperficial fineness, and will be splashed to the smooth slippage of surperficial particle and metal drop, avoided scalding owing to spattering the cable bad that particle causes.This structure adopts self-locking type spiral or buckle structure, and flexibility is good, reduces the weight being subject in use procedure simultaneously and clashes into the damage to cable, meets the instructions for uses such as torsional bending in the normal use procedure of cable completely.
