Abstract
The invention provides a multi-functional modular strain insulator string for a power transmission and distribution line. The multi-functional modular strain insulator string is composed of a single lug ring, a housing, an open spring ring, a supporting column, a double-ear support, a short arc striking rod, a long arc striking rod 9 and a grounding ring. The multi-functional modular strain insulator string has an electric pole protection function: when wind which acts on a conductor achieves a certain force, the inclined circular surface of the supporting column acts on the spring ring so as to force the spring ring to expand outwards, and the supporting column and the conductor slip out together, and therefore, an electric pole can be prevented from being fractured. The multi-functional modular strain insulator string has a bird attack prevention function: pricking pins are arranged among the sheds of the insulator, and the head of each pricking pin is in a sharp-corner shape, and therefore, insulation flashover and tripping caused by a situation that flying birds rest and defecate on an insulator can be avoided. The multi-functional modular strain insulator string has a lightning-caused line fracture prevention function: the long arc striking rod and the short arc striking rod are arranged at two sides of the insulator, and an optimal discharge gap is set, when the insulator string is subjected to lightning strike, freewheeling power-frequency arc can be led to the discharge gap so as to be burnt, and therefore, a conductor and the insulator can be prevented from being burnt out. The multi-functional modular strain insulator string has an electricity verification and grounding function: the lower right part of the insulator is provided with the grounding ring, so that electricity verification and grounding in maintenance can be facilitated.
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 multifunctional modular 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 multifunctional modular strain insulator string used on a kind of electrical power distribution circuit, this device includes monaural
Link, housing, split circlip, strain insulator, starting rod and ground loop etc.;Built-in one of housing is opened
Mouthful turn, and leave corresponding space, the path section of the dagger being made of one with monaural inserts turn,
Being big footpath section on the right side of it, big path junction is set to oblique angle, forms oblique anchor ring and fillet, monaural ring and a support
Post is made of one, and monaural ring can mount with strain insulator string;Protection electric pole principle: when relatively violent typhoon or strong
Typhoon invades, and when wind-force acts on the force value reaching certain on wire, the oblique anchor ring of dagger 1.1 acts on spring
On the internal ring fillet of circle, forcing turn to expand outwardly, final dagger skids off turn and housing, and with resistance to
Open insulator, wire together comes off, and so far, the power that wind acts on electric pole greatly reduces, and makes electric pole exempt from
Fracture;Being provided with pricker 4.1 between the full skirt of strain insulator, N number of full skirt just has N-1 pricker, and pricker sets
Putting above insulator, pricker head is tip-angled shape, can prevent, body birds stop defecation;Can effectively solve by
The insulation flashover breaking that this causes;Two sides of insulator arrange starting rod, set optimal discharge gap, and thunderbolt is sent out
Time raw, make the power frequency arc of afterflow cause at discharging gap and burn, wire and insulator can be protected to exempt from scaling loss;
The lower right-hand side of insulator is provided with ground loop, it is simple to electrical verification ground connection during maintenance construction;The right side gold of insulator
There is 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.
Embodiment
This multifunctional modular strain insulator string, in electrical power distribution circuit, left shell ears link 2.1
Mounting with iron cross arm, right side monaural ring 1 can mount with the left ears ring 4.1 on strain insulator 4;Its bag
Include monaural link 1, housing 2, split circlip 3, strain insulator 4, short starting rod 5, long starting rod 6
With ground loop etc.;The turn 3 of the built-in opening of housing 2, and give and stay corresponding space, dagger 1.1
Path section inserts turn 3, is big footpath section on the right side of it, and big path junction is set to oblique angle, forms an oblique anchor ring,
Monaural ring 1 is made of one with dagger 1.1;Violent typhoon invades, and wind-force acts on the power reaching certain on wire
During value, the oblique anchor ring of dagger 1.1 acts on the internal ring fillet of turn 3, forces turn 3 to extending out
, final dagger skids off turn 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 makes electric pole exempt from and fractures.
Being provided with pricker 4.1 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.
Two sides of insulator arrange starting rod, set optimal discharge gap, when thunderbolt occurs, make the power frequency of afterflow
Electric arc causes and burns at discharging gap, and wire and insulator can be protected to exempt from scaling loss.
