Description

Multifunctional modular support insulator

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 nature Disaster, is the multifunction protection t shore insulator of a kind of electrical power distribution circuit.

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, 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 tripping operation is that circuit is jumped 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；This kinds all cause the repairing loss that has a power failure Heavy.Our company follows the energy-saving and emission-reduction policy that country advocates, it then follows national grid, Southern Power Grid Company electricity Net reliability, the developing direction of intelligent operational management, specialty research and development are energy-saving, multi-functional, low cost Protection device, the reliability service for intelligent grid escorts.

Summary of the invention:

This multifunctional modular support insulator, reusable, simple for structure, low cost, easy for installation, Highly reliable, it is a kind of distribution line effective multifunction protection t shore insulator.

The technical scheme is that

This multifunctional modular support insulator, upper gold utensil 1 crimps fastening, inserts 4 profit with core rod of insulator Ensureing and wire pressing seat 2 compact siro spinning technology with groove 4.4, inserts 4 other end passes the hole of upper gold utensil 1 upper end, This end has the metal bar of be longer than gold utensil 1 end face cylindric 4.3, it is simple to turn 5 is inserted in, and inserts 4 should Holding fluted 4.1, this groove is inserted in the side convex surface 4.2 of turn 5 and takes the form of inclined plane and also allow for turn 5 and overlap Entering, turn 5 is enclosed within groove 4.1 fastening, and two screw rods are fixed on wire pressing seat 2, and briquetting 3 is inserted in On two screw rods, the upper end of briquetting 2 is hole, and lower end is hook shape, therefore, wire pressing block can rotate up to be easy to Wire is installed, and wire is installed after putting in place putting in place that wire pressing block rotates, then two torque nuts are screwed into screw rod On, and be alternately screwed onto and put in place；Protection electric pole fractures principle: violent typhoon is attacked, and wind-force acts on and reaches on wire During to certain power, turn 5 stress departs from inserts 4, inserts 4, wire pressing seat 2 and briquetting 3 together with lead Landing under alignment, 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 multifunctional modular post insulator subgraph, and Fig. 2 is inserts 4 figure.

Embodiment

Upper gold utensil 1 crimps fastening with core rod of insulator, and it is tight with wire pressing seat 2 that inserts 4 utilizes groove 4.4 to ensure Close connection, inserts 4 other end is through the hole of upper gold utensil 1 upper end, and this end has the cylinder being longer than gold utensil 1 end face The metal bar of shape 4.3, it is simple to turn 5 is inserted in, this end of inserts 4 fluted 4.1, this groove is inserted in spring The side convex surface 4.2 of circle 5 takes the form of inclined plane and also allows for turn 5 and be inserted in, and turn 5 is enclosed within groove 4.1 Fastening, two screw rods are fixed on wire pressing seat 2, and briquetting 3 is inserted on two screw rods, and the upper end of briquetting 2 is Hole, lower end is hook shape, therefore, wire pressing block can rotate up is easy to wire installation, and handle after putting in place installed by wire What wire pressing block rotated puts in place, then two torque nuts is screwed on screw rod, and is alternately screwed onto and puts in place；As schemed Showing, violent typhoon is attacked, and when wind-force acts on the power reaching certain on wire, turn 5 stress departs from inserts 4, The landing downward with wire together of inserts 4, wire pressing seat 2 and briquetting 3, so far, line pole suffers typhoon Active force is greatly reduced, and protection electric pole exempts from and fractures.

This multifunctional modular support insulator divides into steel foot 9, and its side is provided with striking ball 10, towards getting around absolutely The starting rod bent inwards of edge full skirt electric discharge, and set optimal discharge gap with starting rod 7, during thunderbolt, The power frequency arc making afterflow causes and burns at discharging gap, thus protects wire and insulator to exempt from scaling loss.

This multifunctional modular support insulator, its insulating boot 6 is provided with thin bar-shaped bird-scaring unit 11, thus anti- Only birds are stopped stop on the insulator, and defecation causes the defaced tripping operation of circuit.

When repairing repeats hanging wire, only need to recover in turn 5 to groove 4.1, this multifunctional modular props up Post insulator remains to reuse.

This Multifunctional support pillar insulator, should use flange nut on non-lightning protection pillar insulator；

This Multifunctional support pillar insulator, should use torque nut on lightning protection pillar insulator；

This Multifunctional insulator, on lightning protection pillar insulator when bare wire, at clamp gold utensil arcuate groove not

Ratchet need to be installed；

This Multifunctional support pillar insulator, is also applied for mucilage binding formula pillar porcelain insulator；

This Multifunctional support pillar insulator, simple and compact for structure, dependable performance, easy for installation.
