Summary of the invention
The purpose of this utility model is to provide a kind of colliery frequency conversion power cable with the control core; can effectively reduce or eliminate the induced harmonics that is produced by induction; reduce the harmonic voltage that the power core is born, thus the protection power cable, the fail safe of raising underground work.
For achieving the above object, the utility model adopts following technical proposals:
A kind of colliery frequency conversion power cable with the control core, by three power cores, earth connection core conductor and control core are formed cable conductor, the power line core conductor has insulating barrier and screen outward, the control line core conductor has insulating barrier and screen outward, it is outer to be the semi-conductive cloth tape layer, said power core, earth connection core conductor and control core are formed cable conductor, said earth connection core conductor and control core respectively have 3, said ground connection core and control core place respectively between per two power cores, wrapped semi-conductive cloth tape layer outside said cable conductor, outside said wrapped semi-conductive cloth tape layer is total metal screen layer, extrudes oversheath outside said total metal screen layer.
In technique scheme, said control line core conductor insulating barrier outer shielding layer is the tight braid of aluminium-plastic tape and copper wire.
In technique scheme, said control line core conductor insulating barrier outer shielding layer is wrapped aluminium-plastic tape.
In technique scheme, said control line core conductor insulating barrier outer shielding layer is wrapped copper strips.
In technique scheme, said total metal screen layer is a braiding copper wire braid.
In technique scheme, said total metal screen layer is wrapped aluminium-plastic tape.
In technique scheme, said total metal screen layer is wrapped copper strips
In technique scheme, said oversheath is the high flame retardant neoprene.
In technique scheme, said oversheath is the high flame retardant chlorosulfonated polyethylene.
In technique scheme, said oversheath is the high flame retardant haloflex.
The utility model has more following effects and good effect:
The utility model provides a kind of colliery frequency conversion power cable with the control core; because the ground connection core is three; place three power core gaps respectively; the distribution that is centrosymmetric of power core and ground connection core; because lead exchanges effect and symmetrical balance; can reduce or eliminate the induced harmonics that produces by frequency conversion; reduce the harmonic voltage that the power core is born; thereby protected power cable; simultaneously; be provided with the earth connection core conductor between wrapped semi-conductive cloth tape layer and said oversheath, the double metal screen layer of doing of said earth connection core conductor can improve the fail safe of underground work.
