Abstract
The invention discloses an anti-interference cable for a balance of plant (BoP) of a nuclear power station. The anti-interference cable comprises a cable core in the middle, wherein a low-smoke zero-halogen and flame-retardant oxygen barrier layer is extruded outside the cable core; a shielding layer is wound outside the oxygen barrier layer; a low-smoke zero-halogen and flame-retardant inner sheath, an interlocked armor layer, a zero-halogen winding belt and a low-smoke zero-halogen and flame-retardant cross-linked polyolefin sheath are sequentially arranged outside the shielding layer; the cable core is formed by stranding three-phase wire cores; the wire cores comprise a conductor which is arranged in the middle and double-layer insulators which are coated outside the conductor; and the double-layer insulators are formed by extruding a radiating polyethylene inner insulating layer and a radiating low-smoke zero-halogen and flame-retardant outer insulating layer. The anti-interference cable has excellent functions of environmental friendliness, anti-interference, prevention of external mechanical damage, long service life and the like, can be applied to the BoP, a conventional island low-voltage power supply system and a transformer, and has a good social benefit and a good economical benefit.
Description
Technical field
The invention belongs to the electric wire field, refer in particular to a kind of nuclear power station BOP and use anti-tampering low-voltage cable.
Background technology
At present; Nuclear power station BOP (Balance Of Plant; Bascule) used low-voltage power supply is single with the construction of cable, in transmission current, produces electromagnetic interference, around giving miscellaneous equipment with self bring some problems; The misoperation of nuclear power appearance control equipment may be caused, the nuclear safety requirement can not be satisfied.
Summary of the invention
Technical problem to be solved by this invention provides a kind of strong interference immunity, and volume is little, and the high nuclear power station BOP of stability uses lv power cable, to satisfy the nuclear safety requirement.
A kind of nuclear power station BOP of the present invention uses anti-tampering cable; Cable core in the middle of it comprises; Outside cable core, extrude the LSOH anti-flaming oxygen barrier layer; The outer lapped shielding layer of LSOH anti-flaming oxygen barrier layer is provided with low-smoke non-halogen flame-retardant inner sheath, lock armo layer, Halogen twining package tape and LSOH anti-flaming cross-linked polyolefin sheath successively outside screen.
Said cable core forms by the three-phase core is stranded, and said core comprises middle conductor and be coated on the outer double hyer insulation of conductor that double hyer insulation adopts irradiated polyethylene inner insulating layer and irradiation LSOH anti-flaming external insulation layer to extrude jointly and forms.
As improvement of the present invention, screen adopts the soft copper silk to dredge around adding reverse wrapped copper strips, and the lock armo layer adopts zinc-plated thin round steel wire to add the wrapped armouring of galvanized steel strip
The present invention has environmental protection, anti-interference, anti-extraneous mechanical damage, and the function of many excellences such as long service life can be used for BOP, conventional island low-voltage power supply system and transformer and uses, and has good social benefit and economic benefit, is specially:
1, the present invention adopts the stranded stranding of three-phase master core; Outside oxygen barrier layer, adopt to dredge around the soft copper silk add copper strips as N line (neutral line), PE line (protective earthing line) or protective earthing-neutral conductor (neutral line and protective earthing are shared), the cross-sectional sizes of screen identical with cable phase line cross section or half.Because copper wire, copper strips play excellent shielding effect, prevent inside and outside electromagnetic interference, improve the stability of equipment.
2, copper wire adds copper strips and dredges outside oxygen barrier layer among the present invention, has not only played shielding action but also has played the effect of conducting short circuit current.
3, project organization of the present invention reduces the external diameter of cable itself, has practiced thrift material and has saved installing space simultaneously, again because of three master core independence strandings; The Stability Analysis of Structures of cable; Reduce the three-phase impedance unbalance, thereby reduced three-phase current unbalance, improved the security reliability of electric power system.
4, be provided with steel wire+steel band lock armo among the present invention in the outer jacket, improve the anti-extraneous mechanical damage ability of whole cable.
5, cross-linked polyolefin and LSOH anti-flaming double hyer insulation are adopted in insulation among the present invention; Dielectric loss is little, and insulation property are high, the life-span long (60 years); Satisfy third generation nuclear power service requirement; Adopt oxygen barrier layer, low-smoke non-halogen flame-retardant inner sheath, LSOH anti-flaming cross-linked polyolefin sheath, triple protection is guaranteed cable Halogen, low cigarette, anti-flammability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Further specify the present invention below in conjunction with accompanying drawing.
As shown in Figure 1; Main body of the present invention is a cable core; Core is formed by the three-phase core is stranded by the centre, and core is made up of the conductor 1 of centre and the double hyer insulation 2 that is coated on outside the conductor, and double hyer insulation 2 adopts irradiated polyethylene inner insulating layers and irradiation LSOH anti-flaming external insulation layer to extrude jointly and forms.Outside cable core, extrude LSOH anti-flaming oxygen barrier layer 3; Oxygen barrier layer 3 outer wrapped employing soft copper silks are dredged around the screen that adds reverse wrapped copper strips 4; Outside screen 4, be provided with low-smoke non-halogen flame-retardant inner sheath 5 successively, adopt zinc-plated thin round steel wire to add the wrapped lock armo layer 6 of galvanized steel strip, Halogen twining package tape 7 and LSOH anti-flaming cross-linked polyolefin sheath 8.
Above-mentioned these execution modes only are used to explain the present invention, but do not limit the scope of the invention, and after having read the present invention, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the present invention.
