Abstract
A mining cable with flexibility and monitoring function belongs to the mining power cable technical field, and aims to enable the cable to be repeatedly installed and recycled for usage, and the cable has the monitoring function. The technical scheme is that a main core wire is a twisted thin copper wire, and a single wire diameter is 0.2-0.4mm, a pitch of a mobile flexible cable is used, and an armor layer is braided by thin steel wires; a semiconductor shielding layer is connected with a monitoring line; a control core wire is added in an inner sheath; the monitoring line and the control core wire are connected with a high voltage vacuum power distribution unit. The flexibility of the cable is improved, so the cable can be repeatedly installed and recycled for usage; the monitoring core wire and a ground wire are mutually insulated, and the mining explosion suppression type high voltage vacuum power distribution unit is configured to form a cable monitoring protection circuit; when the cable is extruded and pressed, the monitoring protection circuit firstly moves and cuts off the power in advance, thereby preventing sparkle generation, person electric shock, gas and coal dust blast accidents, and ensuring safety production of the mine.

Technical field
The utility model relates to a kind of colliery and fixedly lays flame-proof power cable with rated voltage 10KV and following copper core, belongs to mining power cable technical field.
Background technology
At present, the main heart yearn of existing cross-linked polyethylene insulated power cable for coal mines adopts blister copper silk, adds armour, so cable is harder.Give and repeatedly to install and recovery brings difficulty, therefore be only applicable to fixedly lay, the facility that can not need to repeatedly install and reclaim for mobile substation etc. is used, existing power cable with cross-linked polyethylene insulation can not avoid producing electric spark when suffering outside destroy simultaneously, even can there is line to line fault and cause strong electric arc, there is very large potential safety hazard.Therefore existing mining power cable with cross-linked polyethylene insulation being improved, is very urgent task to adapt to the needs of production.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Coal Electricity cable with pliability and monitoring function, this power cable can overcome the shortcoming that existing cross-linked polyethylene insulated power cable for coal mines is only applicable to fixedly lay, can repeatedly install and reclaim, and can be used for realizing that high-voltage vacuum distribution equipment tripping operation (as gas exceeding limit power-off, the power-off of transformer overtemperature etc.) is controlled in a distant place or as other purposes, and can prevent from producing electric spark when cable suffers outside destroy.
The technical scheme solving the problems of the technologies described above is:
A kind of Coal Electricity cable with pliability and monitoring function, its structure comprises main heart yearn, insulating barrier, main heart yearn screen, inner sheath, shield semiconductors layer, middle sheath, armour, oversheath, its improvements are, main heart yearn is stranded thin copper wire, filament diameter 0.2～0.4mm, the pitch of using mobile flexible cable, armour is woven by finer wire.
The above-mentioned Coal Electricity cable with pliability and monitoring function, described shield semiconductors layer is connected with pilot wire, and pilot wire is drawn with high-voltage vacuum distribution equipment and is connected.
The above-mentioned Coal Electricity cable with pliability and monitoring function, has increased control heart yearn in described inner sheath, control heart yearn and be wrapped with control core insulation layer, controls heart yearn and is connected with high-voltage vacuum distribution equipment.
The above-mentioned Coal Electricity cable with pliability and monitoring function, described main heart yearn screen is that copper wire is wrapped, with the finer wire mesh grid of armour jointly as ground wire, shield semiconductors layer by semi-conductive tape wrapped with thin copper wire dredge around combined surveillance layer, by thin copper wire, drawn as pilot wire, inner sheath, middle sheath are enclosed within respectively inner side and the outside of shield semiconductors layer as the insulating sleeve between ground wire and pilot wire.
The beneficial effects of the utility model are:
The utility model is used thin copper wire, fine pith instead main heart yearn, armour is used finer wire braiding instead, has improved the pliability of cable, both can be used as attached cable and has laid, can be used as again the cable of repeatedly installing and reclaiming and use, the feed cable that can be used as mobile substation is used; Shield semiconductors layer is drawn with pilot wire, coordinates high-voltage vacuum distribution equipment to realize the supervision of cable and protection; Control heart yearn and can realize the functions such as gas power-off; Monitor heart yearn and ground wire mutually insulated, coordinate flameproof high-voltage vacuum distribution equipment for mining, form cable and monitor protective circuit, when cable is squeezed, presses, monitor that first protective circuit move, cut off the electricity supply in advance.Reach stop electric spark generation, stop the object of personal electric shock and gas, dust explosion accident, guarantee the safety in production of mine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, mark is as follows: main heart yearn 1, insulating barrier 2, main heart yearn screen 3, inner sheath 7, shield semiconductors layer 8, middle sheath 9, armour 10, oversheath 11.
Embodiment
Structure of the present utility model comprises main heart yearn 1, insulating barrier 2, main heart yearn screen 3, control heart yearn 4, controls core insulation layer 5, filling 6, inner sheath 7, shield semiconductors layer 8, middle sheath 9, armour 10, oversheath 11.
In figure, show, main heart yearn 1 is stranded thin copper wire, filament diameter 0.2～0.4mm, and the fine pith of use mobile flexible cable, armour 10 is woven by finer wire.The improvement of this structure has improved the pliability of cable, and diameter is little, lightweight, so cable is soft, is easy to dish " 8 " word, is applicable to the occasion repeatedly installing and reclaim, for example the power supply of mobile substation.
In figure, show; shield semiconductors layer 8 be semi-conductive tape wrapped with thin copper wire dredge around combined surveillance layer; by thin copper wire, drawn as pilot wire, pilot wire is drawn with high-voltage vacuum distribution equipment and is connected, and coordinates high-voltage vacuum distribution equipment to realize the supervision of cable and protection.
In figure, show, in inner sheath, increased control heart yearn 4, control heart yearn 4 and be wrapped with control core insulation layer 5, control heart yearn 4 and be connected with high-voltage vacuum distribution equipment, can be used for realizing that a distant place controls that high-voltage vacuum distribution equipment trips (as gas exceeding limit power-off, the power-off of transformer overtemperature etc.) or as other purposes.
In figure, show, main heart yearn screen 3 is that copper wire is wrapped, with the finer wire mesh grid of armour 10 jointly as ground wire, the insulation between ground wire and the pilot wire of shield semiconductors layer 8 by inner sheath 7, in sheath 9 jointly realize.
