Description
Technical field:
The present invention relates to electrical power distribution line security and run field, strain insulator electric pole can be taken precautions against and fractureed by violent typhoon,
Defecation initiation is short-circuit trips because flying bird stops to take precautions against strain insulator, can take precautions against lightning-caused breaking, be a kind of electricity
Power transmission line comparatively ideal multifunction protection type strain insulator string.
Background technology:
The mankind, during development, propose requirement higher, that update to the energy.Meanwhile, tellurian
Greenhouse gas emission also will be more lasting growth, the development for social environment brings bigger pressure.Mesh
Before, countries in the world propose environmental protection, efficient, safe, energy-conservation theory in succession.In this theory, want
Really realize the efficient, safe and environment-friendly and energy-conservation of energy supply, it is necessary to the appearance of intelligent grid.Strengthen
Typhoon, thunderstorm encroach on suffer a loss to power system inestimable;According to relevant report, this year is the most superpower
Typhoon invades, and causes the many electric poles of electrical power distribution circuit to fracture, and therefore power failure repairing is suffered heavy losses, if changed
Dress high-strength electric pole, and cost is high;The procreation of birds is incremented by the most therewith;Report according to many ground power department,
Electrical power distribution circuit is voided excreta by birds, and even nesting etc. thus causing insulation flashover breaking is that circuit falls
The one of the main reasons of lock;With global warming, lightning electricity ring meteorology is growing on and on, and thunderbolt causes electric power
The loss of system is obvious to all, and the lightning-caused breaking of insulated conductor occurs again and again;All this kind causes the repairing that has a power failure to damage
Lose heaviness.Our company follows the energy-saving and emission-reduction policy that country advocates, it then follows national grid, Southern Power Grid Company
The intelligentized developing direction of Regulation, specialty researches and develops energy-saving, the multifunction protection strain insulator of low cost
Insulator chain, the reliability service for intelligent grid escorts
Summary of the invention:
This device is a kind of comparatively ideal multi-functional strain insulator string of electrical power distribution circuit.
The technical scheme is that
The multifunction protection type strain insulator string used on a kind of electrical power distribution circuit, this device includes monaural
Link, housing, split circlip, dagger, ears support, centring ring, strain insulator, starting rod and
Ground loop etc.;The turn of the built-in opening of housing, and leave corresponding space, the path section of dagger is inserted
Entering turn, be big footpath section on the left of it, big path junction is set to oblique angle, forms oblique anchor ring and a fillet,
Monaural ring and dagger are spirally connected fastening, also can be mounted (see Fig. 2) by pivot pin, and two ears supports are spirally connected the most respectively
It is fastened on housing outer ring surface, it is possible to be set to one (see Fig. 2), can mount with cross-arm, monaural ring energy and strain insulator
Insulator chain mounts;Protection electric pole principle: when relatively violent typhoon or violent typhoon invade, and wind-force acts on wire
When reaching certain force value, the oblique anchor ring of dagger 4 acts on the internal ring fillet of turn, forces turn
Expanding outwardly, final dagger skids off turn and housing, and together comes off with wire, and so far, wind acts on
Power on electric pole greatly reduces, and makes electric pole exempt from and fractures;Pricker 7.1, N it is provided with between the full skirt of strain insulator
Individual 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;Can effectively solve the insulation flashover breaking thereby resulted in;Two sides of insulator arrange striking
Rod, sets optimal discharge gap, when thunderbolt occurs, makes the power frequency arc of afterflow cause at discharging gap and burn, energy
Protection wire and insulator exempt from scaling loss;The lower right-hand side of insulator is provided with ground loop, it is simple to during maintenance construction
Electrical verification ground connection;The right side gold utensil of insulator has a various ways, biaurite, have monaural, have fourth head,
To adapt to different needs.
Accompanying drawing illustrates:
Fig. 1 is that multi-functional strain insulator protects insulator chain assembling figure.
Fig. 2 is another kind of elastic force guard bar device figure.
Embodiment
This multifunction protection type strain insulator string, in electrical power distribution circuit, the ears link in left side and ferrum
Cross-arm mounts, and right side gold utensil can mount with wedge clamp;It include monaural link, housing, split circlip,
Dagger, ears support, centring ring, strain insulator, starting rod and ground loop etc.;Built-in one of housing is opened
Mouthful turn, and give and stay corresponding space, the path section of dagger inserts turn, is big footpath section on the left of it,
Big path junction is set to oblique angle, forms an oblique anchor ring, monaural ring and dagger and is spirally connected fastening, also can be by pivot pin
Mounting (see Fig. 2), and positioned by two lugs 2.1 on housing, ears support is spirally connected the most respectively and is fastened on shell
On external anchor ring, it is possible to be set to one (see Fig. 2);Violent typhoon invades, and wind-force acts on and reaches certain on wire
Force value time, the oblique anchor ring of dagger 4 acts on the internal ring fillet of turn, forces turn to expand outwardly,
Final dagger skids off turn and housing, and together comes off with wire and strain insulator string, and so far, wind is made
The power being used on electric pole greatly reduces, and makes electric pole exempt from and fractures.
Being provided with pricker 7.1 between the full skirt of strain insulator, pricker is arranged on the top of insulator, pricker head
For tip-angled shape, can prevent, body birds stop defecation;Can effectively solve the insulation flashover breaking thereby resulted in.
