Abstract
The invention discloses a variable frequency cable, the middle part of the cable is a cable core, the cable comprises three main insulated wire cores and three zero line cores, wherein optical units are arranged in the cable core or the gaps of the main insulated wire cores and the zero line cores, and a metal shielding layer, a longitudinal wrapped aluminum-plastic composite layer, a spacer sleeve, an armor layer and an outer sheath are sequentially arranged at the outer part of the cable core. The variable frequency cable enhances the functions of the common variable frequency cable, has the functions of alarming, temperature measuring, state monitoring, frequency back feeding, signal transmitting and the like, meanwhile, the novel totally-enclosed waterproof structure is completely waterproof and simultaneously has the anti-corrosion function, so the special requirements of modern high-frequency electric machines and variable frequency electric appliances on the variable frequency cable under severe conditions are satisfied.
Description
Technical field
The present invention relates to a kind of cable, specifically is a kind of improvement of frequency-changing cable.
Background technology
As everyone knows; conventional frequency-changing cable is to thoroughly do away with outside edge and three zero line cores three to set gradually lapping layer; metal screen layer and outer jacket constitute; form the 3+3 structure; make cable have stronger proof voltage impact; pulse voltage in the time of standing at a high speed frequent frequency conversion; frequency converter there is good protective action; yet along with industrial development and growth in the living standard; variable-frequency motor; appliance applications is to the every field that relates to national economy and corner; conventional frequency-changing cable can not satisfy the particular field demand under the severe environmental conditions in one's power, and its single function also can't satisfy intelligentized development it is had monitoring simultaneously; feedback information; the demand of functions such as signal transmission.
At present, the cables manufacturing enterprise that has improves the problems referred to above, as Chinese patent " a kind of high temperature high voltage resistant frequency-changing cable " (publication number 202134267U, open day 2012 month February 1) a kind of frequency-changing cable with high temperature resistant function is disclosed in, but it has been ignored in the extreme humidity even has had in the environment of moisture existence, hydrone is to invasion, the destruction of frequency-changing cable, thus influence and can't guarantee the useful life of cable and the safety of equipment.And Chinese patent " frequency-changing cable " (publication number 201622866U; open day on November 3rd, 2010) in a kind of silastic material that utilizes is disclosed as the sheath of cable; its essence also is to have improved merely under the hot environment externally the protection of cable, still can't satisfy the needs on the aforesaid function.At Chinese patent " frequency-changing cable " (publication number 101635179; open day on January 27th, 2010) disclose in the screen of this cable and comprised aluminium foil layer; played waterproof action to a certain extent; but having ignored, it has under the situation of moisture immersion; aluminium foil can very fast oxidation; at this moment to the damaging influence of cable self considerably beyond its defencive function; all do not consider the improvement of frequency-changing cable on the side signal transmission surface function by retrieval discovery Chinese patent simultaneously; all inequality has good on-line monitoring; functions such as feedback information and signal transmission, nature can't satisfy the new period and following to the demand on the frequency-changing cable function.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of water resistance good, increase the optical fiber composite water-proof type frequency-changing cable of functions such as warning, temperature survey, status monitoring, frequency feedback, signal transmission simultaneously.
A kind of frequency-changing cable of the present invention, be cable core in the middle of this cable, described cable core comprises three main insulation cores and three zero line cores, place, slit middle at cable core or main insulation core and zero line core is provided with the light unit, cable core sets gradually metal screen layer outward, vertical alclad is moulded composite bed, separation sleeve, armour and oversheath.
Described main insulation core comprises the master core conductor, sets gradually master core insulating barrier, master core metal screen layer outside the master core conductor.
Described zero line core comprises the zero line core conductor, sets gradually zero line core insulation layer, zero line core metal screen outside the zero line core conductor.
Described smooth unit comprises monomode fiber and multimode fiber.
Beneficial effect of the present invention:
Greatly strengthened the function of conventional frequency-changing cable, make it have functions such as warning, temperature survey, status monitoring, frequency feedback, signal transmission, and totally enclosed new-type waterproof construction fully has corrosion-resistant function again in the waterproof, satisfy under the mal-condition and modern high-frequency electric machines and frequency conversion electrical equipment to the specific requirement of frequency-changing cable.Connect except being used for normal frequency conversion electrical equipment, also can be used for having waterproof requirement and or frequency conversion electrical equipment had the specific function of intelligent monitoring requirement, played important auxiliaryly and support the effect that promotes for development of new electrical equipment, intelligent electric appliance, meaning is very big.
Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment:
As Fig. 1, frequency-changing cable of the present invention, the centre is cable core, and cable core comprises three main insulation cores and three zero line cores, and wherein, the main insulation core comprises master core conductor 1, sets gradually master core insulating barrier 2, master core metal screen layer 3 outside master core conductor 1.The zero line core comprises zero line core conductor 4, sets gradually zero line core insulation layer 5, zero line core metal screen 6 outside zero line core conductor 4.Place, slit middle at cable core or main insulation core and zero line core is provided with light unit 12, and cable core sets gradually metal screen layer 7 outward, and vertical alclad is moulded composite bed 8, separation sleeve 9, armour 10 and oversheath 11.
The present invention is divided into three parts with the ground core of conventional electric power cable, difference extruded insulation layer, three zero line cores of three main insulation cores and fractionation are arranged metal screen layer respectively constitute stranding after the split screen structure, during stranding with the core space at three main insulation cores placed apart, three ground, prefabricated in advance light unit need be placed on the stranding center simultaneously, continue to arrange metal level outside the cable core behind stranding, constitute total screen structure, vertical alclad is moulded composite bed then, constitute totally-enclosed waterproof construction, should outside the plastic-aluminum watertight composition, extrude the separation sleeve with water-proof function as the need armouring, extrude the oversheath of waterproof behind the armouring.
The insulating material of main insulation core and zero line core can be polyvinyl chloride, polyethylene, crosslinked polyethylene, fluoroplastics, silicon rubber, ethylene-propylene diene copolymer, natural rubber, elastomer etc.;
