Abstract
The invention discloses a high-voltage power supply and communication composite cable for a mine shaft. The composite cable comprises high-voltage power transmission units, and a fastening tape, an inner sheath, an armor layer and an outer sheath which are coated outside the high-voltage power transmission units sequentially, wherein a communication unit is arranged in a gap formed between the high-voltage power transmission units in the fastening tape; and the communication unit comprises communication cores, and a communication tape, a communication copper wire shielding layer, a communication copper strip shielding layer and a communication unit sheath which are coated outside the communication cores sequentially. By the high-voltage power supply and communication composite cable for the mine shaft with the structure, because the communication copper wire shielding layer and the communication copper strip shielding layer are arranged between the communication tape and the communication unit sheath of the communication unit, higher harmonic and electromagnetic interference generated in operation of the high-voltage power transmission units can be effectively shielded, transmission of a communication signal is not influenced, and a cable can transmit power and communicate.
Description
Technical field
The present invention relates to the comprehensive cable of a kind of transmission communication signal simultaneously and electric power, especially relate to a kind of mining vertical shaft high voltage supply and communication comprehensive cable.
Background technology
The structure of high-tension cable is general mainly to comprise the high-tension electricity transmission unit, be coated on this high-tension electricity transmission unit outer fastening band, inner sheath, armour and oversheath in order; Said high-tension electricity transmission unit comprises the transmission of electricity core; Be arranged on this transmission of electricity core outer conductor shield, insulation filling layer, insulation screen and copper strips screen in order, the high-tension cable of said structure can be used for underground mine use electricity equipment or electric substation are carried high-tension electricity.The down-hole is except power consumption equipment; Also has communication apparatus; Also need be sent to the communication apparatus of down-hole to communication signal through communication cable, the structure of communication cable commonly used mainly comprises the communication core, is coated on this communication core outer band and sheath in order at present.Since the high order harmonic component of high-tension cable generation in service and electromagnetic interference can the interference communications cable the signal transmission, so can not be simply be made into a cable to high-tension cable and communication cable and realize multi-purpose.So in order to satisfy the needs of underground mine use electricity equipment and communication, general way is laying installation high voltage supply cable and communication cable respectively at present, lays the problem of bringing and be but install respectively: (1), increase mounting cost increases maintenance cost.(2), respectively laying installation needs two installation channel, two covers lay facility, the usage space of also having wasted the down-hole.(3), need choose service cable and communication cable respectively, increased the cost of choosing of cable.When 4, communication cable lays separately,, hundreds of rice or darker is arranged, because action of gravity to the stress rupture that communication cable produces, has influenced the useful life of communication cable apart from ground because mine is generally very dark.
Summary of the invention
The technical problem that the present invention will solve provides an a kind of cable can realize that high voltage supply can realize mining vertical shaft high voltage supply and communication comprehensive cable that the high order harmonic component of communication need and high-tension cable generation in service and the normal communication that electromagnetic interference can not hinted obliquely at communication cable require again.
For solving the problems of the technologies described above; The present invention is mining vertical shaft high voltage supply and communication comprehensive cable comprises the high-tension electricity transmission unit, is coated on this high-tension electricity transmission unit outer fastening band, inner sheath, armour and oversheath in order; Said high-tension electricity transmission unit comprises the transmission of electricity core; Be arranged on this transmission of electricity core outer conductor shield, insulation filling layer, insulation screen and copper strips screen in order; The space that forms between the high-tension electricity transmission unit in the said fastening band is provided with communication unit, and this communication unit comprises the communication core, is coated on this communication core outer communication band, communication copper wire screen, communication copper strips screen and communication unit sheath in order.
Adopt the mining vertical shaft high voltage supply and the communication comprehensive cable of said structure; Owing between the communication band of communication unit and communication unit sheath, set up communication copper wire screen and communication copper strips screen; Therefore can mask the high order harmonic component and the electromagnetic interference of the generation in service of high-tension electricity transmission unit effectively, can not influence the transmission of communication signal.In addition; Because communication unit is arranged on the gap that forms between the high-tension electricity transmission unit in the said fastening band; And be filled with filler, make communication unit and the high-tension electricity transmission unit one integrated mass of combining closely, be arranged on the effect of outer fastening band, inner sheath, armour and oversheath of high-tension electricity transmission unit in addition; Therefore can not produce because action of gravity to the stress rupture phenomenon that communication unit produces, can not influence the useful life of communication unit.
