Abstract
The invention provides a multifunctional protecting post insulator. A wire clamping base 1 in an insulating cover 5 is crimped and fastened to a core rod of a lightning-proof insulator; two breaking groove-containing screw rods 3 with V-shaped grooves (3.1) are fixed on the wire clamping base 1; a wire crimping block 2 with V-shaped grooves (2.1) sleeves the two breaking groove-containing screw rods 3; and a hole is formed in the upper end of the wire crimping block 2 and the lower end is in a hook form, so that the wire crimping block can rotate upwards to facilitate wire installation; the wire crimping block rotates downwards in place after a wire is installed in place; and two torque nuts are screwed into the groove-containing screw rods 3 and are alternately screwed in place. According to the pole protection principle, when the wind action reaches certain force on the wire in a severe typhoon attack, the V-shaped grooves (3.1) of the two groove-containing screw rods are stretched to crack and the wire slips downwards, so that the action force of the typhoon on a line pole is greatly reduced; and the pole is prevented from being broken off. A steel leg is arranged at the lower part of the multifunctional protecting post insulator; an arc striking ball is arranged at one side of the steel leg; an arc striking rod discharges around umbrella skirts of the insulator and is bent inwards; an optimal discharge gap is set between the insulator and the arc striking rod 7; and a power-frequency arc of a follow current is led to the discharge gap for burning in a lightning stroke, so that the wire and the insulator are prevented from being burnt out. According to the multifunctional protecting post insulator, the insulating cover 5 is provided with thin rod-like bird repellers 11, so that the problem that the line is stained for tripping since birds stop and stay on the insulator to defecate is prevented. The insulator is a four-in-one multifunctional product of achieving wire insulating support, wind prevention and pole protection, arc striking and lightning protection and bird damage prevention; the insulator can be repeatedly used only by exchanging the two breaking groove-containing screw rods or the wire crimping block when the line is repaired and repeatedly suspended; and the insulator has the characteristics of being simple and compact in structure, convenient to install, simple in line, low in cost and the like.
Description
Technical field:
The present invention relates to electrical power distribution line security and run field, circuit can be taken precautions against and suffer increasingly severe natural disaster, be the multifunction protection t shore insulator of a kind of electrical power distribution circuit.
Background technology:
The energy, in the process of development, is proposed requirement higher, that update by the mankind.Meanwhile, the growth that tellurian greenhouse gas emission also will be more lasting, the development for social environment brings bigger pressure.At present, countries in the world propose environmental protection, efficient, safe, energy-conservation theory in succession.In this theory, want really to 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, Super Typhoon several times invaded, and caused the many electric poles of electrical power distribution circuit to fracture, and therefore power failure repairing is suffered heavy losses, if changing the outfit high-strength electric pole, and cost is high；The procreation of birds is also incremented by therewith；Reporting according to many ground power department, electrical power distribution circuit is voided excreta by birds, even nests etc. thus causing insulation flashover breaking is the one of the main reasons of circuit breaking；With global warming, lightning electricity ring meteorology is growing on and on, and the loss causing power system of being struck by lightning is obvious to all, and the lightning-caused breaking of insulated conductor occurs again and again；All this kind causes power failure repairing to suffer heavy losses.Our company follows the energy-saving and emission-reduction policy that country advocates; follow the developing direction of national grid, Southern Power Grid Company electric network reliability, intelligent operational management; specialty research and development are energy-saving, the protection device of protection type, low cost, and the reliability service for intelligent grid escorts.
Summary of the invention:
This multifunction protection t shore insulator, reusable, simple for structure, cost is low, easy for installation, highly reliable, be a kind of effective multifunction protection t shore insulator of distribution line.
The technical scheme is that
This multifunction protection t shore insulator; tension seat 1 crimps fastening with core rod of insulator; two are fixed on tension seat 1 containing groove screw rod 3, and wire pressing block 2 is inserted in two containing on groove screw rod 3, and the upper end of wire pressing block 2 is hole; lower end is hook shape; therefore, wire pressing block can rotate up is easy to wire installation, and wire is installed after putting in place putting in place that wire pressing block rotates; again two torque nuts are screwed into containing on groove screw rod 3, and are alternately screwed onto and put in place；Protection electric pole fractures principle: violent typhoon is attacked; wind-force acts on when reaching certain power on wire; two V-shaped groove 3.1 place Tensile fractures containing groove screw rod 3; or cause the downward landing of wire with V-shaped groove (2.1) wire pressing block 2; so far; line pole is greatly reduced by the active force of typhoon, and protection electric pole exempts from and fractures.
Accompanying drawing illustrates:
Fig. 1 is multifunction protection t shore insulation subgraph.
Embodiment
Tension seat 1 crimps fastening with core rod of insulator, two are fixed on tension seat 1 containing groove screw rod 3, wire pressing block 2 is inserted in two containing on groove screw rod 3, the upper end of wire pressing block 2 is hole, and lower end is hook shape, therefore, wire pressing block can rotate up is easy to wire installation, wire is installed after putting in place putting in place that wire pressing block is rotated down, then two torque nuts are screwed into containing on groove screw rod 3, and is alternately screwed onto and puts in place；As shown in the figure; during violent typhoon invasion and attack; wind-force acts on when reaching certain power on wire; two V-shaped groove 3.1 places containing groove screw rod or rupture with V-shaped groove (2.1) wire pressing block 2 place Tensile; wire is caused to leave the downward landing of electric pole; so far, line pole is greatly reduced by the active force of typhoon, and protection electric pole exempts from and fractures.
This multifunction protection t shore insulator divides into steel foot 8; its side is provided with striking ball 9; towards the starting rod bent inwards getting around insulator umbrella electric discharge; and set optimal discharge gap with starting rod 7; during thunderbolt; the power frequency arc making afterflow causes discharging gap place and burns, thus protecting wire and insulator to exempt from scaling loss.
This Multifunctional support pillar insulator, its insulating boot 5 is provided with thin bar-shaped bird-scaring unit 11, thus preventing birds from stopping on the insulator stop, defecation causes circuit to be subject to stained tripping operation.
When repairing repeats hanging wire, only exchanging two containing groove screw rod 3, this multifunction protection t shore insulator remains to reuse.
This multifunction protection t shore insulator, should use flange nut on non-lightning protection pillar insulator；
This multifunction protection t shore insulator, should use torque nut on lightning protection pillar insulator；
This multifunction protection t shore insulator, time on lightning protection pillar insulator for bare wire, clamp gold utensil
Arcuate groove place does not need to install ratchet；
This multifunction protection t shore insulator, is also applied for mucilage binding formula pillar porcelain insulator；
