Description
Technical field:
The present invention relates to electrical power distribution line security and run field; can take precautions against strain insulator electric pole fractureed by violent typhoon; can take precautions against strain insulator because of flying bird stop defecation cause short circuit tripping operation, can take precautions against lightning-caused breaking, be a kind of electrical power distribution circuit comparatively ideal multifunction protection type strain insulator string.
Background technology:
The mankind, in the process of development, propose requirement that is higher, that upgrade to the energy.Meanwhile, the growth that tellurian greenhouse gas emission also will continue more, the development for social environment brings larger pressure.At present, countries in the world propose environmental protection, efficient, safe, energy-conservation theory in succession.In this theory, want really to realize efficient, the safety of energy supply, environmental protection and energy-conservation, just need the appearance of intelligent grid.Strengthen typhoon, thunderstorm encroach on suffer a loss to electric power system inestimable; According to relevant report, this year, Super Typhoon invaded several times, and cause the many electric poles of electrical power distribution circuit to fracture, therefore power failure repairing is suffered heavy losses, if change the outfit high-strength electric pole, and cost is high; The procreation of birds also increases progressively thereupon; How according to power department report, electrical power distribution circuit is voided excreta by birds, even to nest etc. thus to cause insulation flashover breaking to be the one of the main reasons of circuit breaking; With global warming, lightning electricity ring meteorology is growing on and on, and thunderbolt causes the loss of electric power system obvious to all, and the lightning-caused breaking of insulated conductor occurs again and again; All this kind causes power failure repairing and suffers heavy losses.Our company follows the energy-saving and emission-reduction policy that country advocates; follow national grid, the intelligentized developing direction of Southern Power Grid Company Regulation; specialty research and development are energy-saving, the multifunction protection strain insulator string of low cost, for the reliability service of intelligent grid escorts.
Summary of the invention:
The technical solution of the utility model is:
The multifunction protection type strain insulator string that a kind of electrical power distribution circuit uses, by monaural ring 1, housing 2, spring coil 3, dagger 4, ears support 5, centring ring 6, insulator 7, short starting rod 8, long starting rod 9 and ground loop 10 are formed, spring coil 3 is contained in the centre of housing 2, there is location lug 2.1 one end of housing 2, dagger 4 is inserted in spring coil 3, and be connected fastening with monaural ring 1, ears support 5 is connected on housing 2 and forms one, insulator 7 is articulated on monaural ring 1, short starting rod 8, long starting rod 9 is screwed onto two sides of insulator 7, and upward, ground loop 10 is screwed onto the right side of insulator 7, and downward.Spring coil 3 is provided with place's opening, and its inner ring angle, one end is fillet or oblique angle.Dagger 4 is set to large segment, and the junction of large segment is provided with special angle, forms an annular slope and fillet.Be provided with pricker 7.1 between the full skirt of insulator 7, the head of every piece of pricker is tip-angled shape.Monaural ring 1 and dagger 4 are spirally connected fastening, also can be mounted (see Fig. 2) by pivot pin, two ears supports 5 are relatively spirally connected respectively and are fastened on housing 2 outer ring surface, also one (see Fig. 2) can be set to, ears support 5 has screw 5.1 can mount with cross-arm, monaural ring 1 can be gone here and there with strain insulator 7 and be mounted; Protection electric pole principle: when comparatively violent typhoon or violent typhoon invade, when wind-force acts on and wire reaches certain force value, the oblique anchor ring of dagger 4 acts on the inner ring fillet of spring coil, spring coil is forced to expand outwardly, final dagger skids off spring coil and housing, and together comes off with wire, so far, the power that wind acts on electric pole greatly reduces, and electric pole is exempted from and fractures; Be provided with pricker 7.1 between the full skirt of strain insulator, N number of full skirt just has N-1 pricker, and pricker is arranged on the top of insulator, and pricker head is tip-angled shape, can prevent, body birds stop defecation; Effectively can solve the insulation flashover breaking caused thus; Two sides of insulator arrange starting rod, and setting optimal discharge gap, when thunderbolt occurs, makes the power frequency arc of afterflow cause discharging gap place and burn, and energy guardwire and insulator exempt from scaling loss; The lower right-hand side of insulator is provided with ground loop, electrical verification ground connection during easy access construction; The right side gold utensil of insulator has various ways, biaurite, have monaural, have fourth head, adapting to different needs.
Accompanying drawing illustrates:
Fig. 1 is multi-functional strain insulator protection insulator string assembly drawing.
Fig. 2 is another kind of elastic force guard bar device figure.
Embodiment
This multifunction protection type strain insulator string, the ears link in left side and iron cross arm mount, and right side gold utensil can mount with wedge clamp; Be made up of monaural ring 1, housing 2, spring coil 3, dagger 4, ears support 5, centring ring 6, insulator 7, short starting rod 8, long starting rod 9 and ground loop 10, spring coil 3 is contained in the centre of housing 2, dagger 4 is inserted in spring coil 3, and be connected fastening with monaural ring 1, ears support 5 is connected on housing 2 and forms one, insulator 7 is articulated on monaural ring 1, short starting rod 8, long starting rod 9 are screwed onto two sides of insulator 7, and upward, ground loop 10 is screwed onto the right side of insulator 7, and downward.Spring coil 3 is provided with place's opening, and its inner ring angle, one end is fillet or oblique angle.Dagger 4 is set to large segment, and the junction of large segment is provided with special angle, forms an annular slope and fillet.Monaural ring and dagger are spirally connected fastening, also can be mounted (see Fig. 2) by pivot pin, and are located by the lug of two on housing 2.1, and ears support is spirally connected relatively respectively and is fastened on housing outer ring surface, also can be set to one (see Fig. 2); Violent typhoon invades, when wind-force acts on and wire reaches certain force value, the oblique anchor ring of dagger 4 acts on the inner ring fillet of spring coil, spring coil is forced to expand outwardly, final dagger skids off spring coil and housing, and together comes off with wire and strain insulator string, so far, the power that wind acts on electric pole greatly reduces, and electric pole is exempted from and fractures.Be provided with pricker 7.1 between the full skirt of strain insulator 7, pricker is arranged on the top of insulator 7, and pricker head is tip-angled shape, can prevent, body birds stop defecation; Effectively can solve the insulation flashover breaking caused thus.Two sides of insulator 7 arrange starting rod, and setting optimal discharge gap, when thunderbolt occurs, makes the power frequency arc of afterflow cause discharging gap place and burn, and energy guardwire and insulator exempt from scaling loss.The lower right-hand side of insulator 7 is provided with ground loop 10, electrical verification ground connection during easy access construction.
When carrying out rushing to repair again hanging wire, this elastic force guard bar device still can use, and but, ears support should be back-outed before using, monaural ring and dagger are turned on, then, dagger inserts in spring coil again, loads centring ring, monaural ring and dagger are spirally connected fastening, be loaded on ears support and cross-arm mounts, monaural ring and strain insulator string mount, and after stringing, wire inserts wedge clamp.
The right side gold utensil of insulator has various ways, to adapt to the needs of different wire clamp.
