Abstract
The utility model discloses a special cable for a mining transducer, which aims at providing a special cable for a mining transducer which can save the manufacturing cost, reduce the strength of the electric field and the density of the magnetic flux surrounding the cable and protect the health of the human body, and consists of three power-wire core conductors (1), three ground-wire core conductors (6), an overall shielding layer (7) and a jacket (8), wherein the power-wire core conductors (1) are provided with an insulation layer (2) and a metal shielding layer (3), and the ground-wire core conductors (6) are provided with a semi-conduction layer (5), stuffing (4) is arranged between the power-wire core conductors (1) and the ground-wire core conductors (6), the power-wire core conductors (1), the stuffing and the ground-wire core conductors (6) are wrapped by the overall shielding layer (7), and the jacket (8) is arranged on the overall shielding layer (7). The special cable for the mining transducer is mainly applied to the mining transducer or the coal mining machine and similar devices.
Description
Technical field
The utility model relates to a kind of mine-used frequency-converter private cable.
Background technology
At present, frequency converter employed cable in colliery is the common mining cable of quadrature arrangement mostly, its finished product external diameter is bigger, the waste raw material, can not suppress the interference of surge voltage that frequency converter produces at work and ultraharmonics near electrical equipment, electric field strength and magnetic density are higher around the cable, and the health of speaking sarcastically is arranged.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of finished product external diameter less; save manufacturing cost; can reduce mine-used frequency-converter at work; the interference that surge voltage that produces and ultraharmonics use near electrical equipment; can also reduce cable electric field strength and magnetic density on every side, the mine-used frequency-converter private cable of protection health.
The technical scheme that the utility model is taked is: it is made up of three power line core conductors, three ground wire core conductors, total screen and sheaths, on the power line core conductor, be provided with insulating barrier and metal screen layer, on the ground wire core conductor, be provided with semi-conductive layer, between power line core conductor and ground wire core conductor, be provided with filling, these three kinds of materials are by total screen parcel, and sheath is located on total screen.
The beneficial effects of the utility model are as follows:
1, produced product external diameter is less, has saved raw material;
2, owing to adopted a plurality of screens, can reduce mine-used frequency-converter at work, the surge voltage of generation and ultraharmonics can reduce cable electric field strength and magnetic flux density on every side to the interference that near electrical equipment uses, and alleviate the infringement to health.
Description of drawings
Accompanying drawing is a section structure schematic diagram of the present utility model.
Among the figure: power line core conductor 1, insulating barrier 2, metal screen layer 3, filling 4, semi-conductive layer 5, ground wire core conductor 6, total screen 7, sheath 8.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
By accompanying drawing as can be known: the utility model is made up of three power line core conductors 1, three ground wire core conductors 6, total screen 7 and sheaths 8, on power line core conductor 1, be provided with insulating barrier 2 and metal screen layer 3, on ground wire core conductor 6, be provided with semi-conductive layer 5, between power line core conductor 1 and ground wire core conductor 6, be provided with and fill 4, these three kinds of materials are by total screen 7 parcels, and sheath 8 is located on total screen 7.
Sheath 8 adopts neoprene to make.Total screen 7 and metal screen layer 3 all can adopt the single kind of copper wire braiding, copper wire winding, aluminium-plastic tape, copper strips or the form of multiple composite construction to make.What semi-conductive layer 5 and filling 4 were all adopted is semi-conductive adhesive.What insulating barrier 2 adopted is that ethylene-propylene diene copolymer is made.
