Abstract
The utility model discloses a movable metal shielded soft cable for a coal mine, which comprises power wires, an earth wire, assistant wires, and fire retarding sheaths coated on the wires, wherein the power wires are arranged symmetrically, and the earth wire is arranged at the geometric center position of the power wires arranged symmetrically; the assistant wires are respectively arranged in the edge gaps of the power wires, and a plurality of filling bars are arranged in the interspaces among the power wires, the assistant wires and the fire retarding sheaths. The cable has the advantages of reasonable and stable structure, uniform electric field distribution, and double functions of monitoring and controlling signals, enhanced use safety of the cable, and improved round appearance of the cable, materials saving for the cable sheathes, and reduced cable cost.
Description
Technical field:
The utility model relates to a kind of cable, just relates to a kind of moving metal shielded flexible cable that is used for the colliery specifically.
Background technology:
In Coal Production, the moving metal shielded flexible cable is mainly used in being connected between the electrical equipment under transformer and the coal mine, colliery cable according to colliery industry standard MT818-1999 production, be generally 4 cored structures, promptly three power lines add a ground wire, add a pilot wire again in individual other model outside three power lines and a ground wire, this root pilot wire can only play simple control action or signal monitoring effect, and such construction of cable has not satisfied the needs of present Coal Production.
The utility model content:
The purpose of the utility model is not enough at above-mentioned existing in prior technology and a kind of moving metal shielded flexible cable that is used for the colliery that provide, it not only has the general performance of colliery with cable, because it is rational in infrastructure, simultaneously possessed the signal monitoring dual-use function again, improved the safety in utilization of cable.
For achieving the above object, the utility model can be achieved through the following technical solutions:
The utility model comprises power line, ground wire and boost line, and is wrapped in the outer fire retardant jacket of above-mentioned lead, and described power line is the symmetric arrays setting, and described ground wire is arranged on the centre of described symmetric arrays power line geometry; Described pilot wire is arranged in the crack, limit of power line; Be provided with many packings in the space between power line, pilot wire and fire retardant jacket.
Described pilot wire is three, and wherein two is pilot, and another root is for monitoring lead, and described supervision lead outer peripheral face is coated with metal screen layer.
Described packing is the six roots of sensation.
Advantage of the present utility model is that described ground wire is arranged on the centre of described symmetric arrays power line geometry because power line is the symmetric arrays setting, and such construction of cable is reasonable, stable, and Electric Field Distribution is even; In the crack, limit of power line, be respectively arranged with pilot wire, wherein two is pilot, and another root is for monitoring lead, and this just makes cable possess the signal monitoring dual-use function simultaneously, has improved the safe handling of cable; Purpose at described supervision lead outer peripheral face clad metal screen is in order to prevent the interference of external signal; The packing that is provided with in the space between power line, pilot wire and fire retardant jacket has not only improved the cable appearance rounding property, and has saved the material usage of cable cover(ing), has reduced cable cost.
Description of drawings:
Fig. 1 is a cross-section structure of the present utility model.
Embodiment:
As shown in the figure, the moving metal shielded flexible cable that is used for the colliery of the present utility model, comprise power line 1, ground wire 2 and pilot wire, and be wrapped in the outer fire retardant jacket 3 of above-mentioned lead, described power line 1 is three and is the symmetric arrays setting that ground wire 2 is arranged on the centre of symmetric arrays power line 1 geometry; Described pilot wire is that wherein two is pilot 5 in three cracks, limit that are arranged on power line 1, and another root is for monitoring lead 6, and described supervision lead 6 outer peripheral faces are coated with metal screen layer; Be provided with six roots of sensation packing 4 in the space between power line 1, pilot wire and fire retardant jacket 3.
