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, six roots of sensation control line conductor, on the power line core conductor, be provided with insulating barrier and metal screen layer, the control line conductor is provided with the control line insulating barrier, per two control line conductors are wrapped in the control line screen, the control line sheath is arranged on the control line screen, be provided with power line core conductor and control line conductor in total screen, space in total screen is provided with filling, and the cylindrical of total screen is provided with inner sheath, braid, oversheath.
The beneficial effects of the utility model are as follows:
1, produced product external diameter is less, has saved raw material;
2, owing to adopt insulation and Shielding Design, can reduce mine-used frequency-converter at work, the surge voltage of generation and ultraharmonics can reduce cable electric field strength and magnetic density on every side to the interference that near electrical equipment uses, and alleviate the infringement to health;
3, owing between inner sheath and oversheath, be provided with the intensity that braid has strengthened cable, prolonged useful life.
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, control line conductor 4, control line insulating barrier 5, control line screen 6, control line sheath 7, filling 8, total screen 9, inner sheath 10, braid 11, oversheath 12.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
By accompanying drawing as can be known: it is made up of the utility model three power line core conductors 1, six roots of sensation control line conductor 4, on power line core conductor 1, be provided with insulating barrier 2 and metal screen layer 3, control line conductor 4 is provided with control line insulating barrier 5, per two control line conductors 4 are wrapped in the control line screen 6, control line sheath 7 is arranged on the control line screen 6, be provided with power line core conductor 1 and control line conductor 4 in total screen 9, space in total screen 9 is provided with fills 8, and the cylindrical of total screen 9 is provided with inner sheath 10, braid 11, oversheath 12.The metal screen layer 3 double ground wires of doing.
