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 adopts the technical proposal that three power-wire core conductors (1) and six control-wire conductors (4) are arranged inside a jacket (8), wherein, the power-wire core conductors (1) are provided with an insulation layer (2) and a metal shielding layer (3), the control-wire conductors (4) are provided with a control-wire insulation layer (5), every two control-wire conductors (4) are wrapped by a control-wire shielding layer (6), and a control-wire jacket (7) is arranged on the control-wire shielding layer (6). 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: be provided with three power line core conductors and six roots of sensation control line conductor in sheath, the power line core conductor is provided with insulating barrier and metal screen layer, the control line conductor is provided with the control line insulating barrier, per two control line conductor Be Controlled line screens wrap up, and the control line sheath is arranged on the control line 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 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.
