Abstract

The invention discloses a lightning arrester of an insulator for a power supply line, in particular relates to an outer-gap lightning arrester. The outer-gap lightning arrester is characterized in that an upper metal tool is provided with a pressure adjustment element, a conductive band, a zinc oxide resistance card, an inner discharge electrode, an insulating gasket and an outer discharge gap rod, wherein a thread upper part of an lower end metal tool is provided with an outer discharge gap sheath, and the shape of the outer discharge gap rod is drooping. The outer-gap lightning arrester disclosed by the invention has the advantages: a tiny residual voltage is introduced into the earth and the protection process of electric equipment is finished when the outer discharge gap rod generated by lightning discharges to the outer discharge gap sheath; therefore, the investment cost and the maintenance cost are reduced; the outer-gap lightning arrester is not influenced by the climatic environment, the atmospheric pollution and the geological conditions; the zinc oxide resistance card is not corroded, and the service life is long; the product made of a silicon rubber material has the advantages of lightness, portability, good insulation property, long creepage distance, convenience for construction, reduced labor intensity and safety, stability and reliability for operation. The lightning protection level of the power supply line is improved, and good effects of small investment, large yield, free-maintenance and over 98% of effective protection probability are achieved.

Description

The external series gap lightning protection device
Technical field
The present invention relates to the lightning protection device of a kind of supply line with insulator, more particularly, a kind of external series gap anti-thunder insulator.
Background technology
The insulating rate improves constantly on 6kV~20kV distribution overhead transmission line, and to prevent the generation of broken string that Lightning Over-voltage causes, tripping operation, insulator breakdown accident, the domestic and international major measure that adopts has at present: the side sets up lightning conducter on the line; At the other zinc oxide arrester that installs additional of post insulator; Directly install starting rod etc. additional at the high voltage load end; But it is higher that these methods still exist cost of investment, and construction and installation are complicated, under severe weather conditions, produces the not blow-out of discharging, and discharging current is bigger, burns problems such as discharging gap and broken string.Especially in the last few years, south, the north, various places, town and country climate change multiterminal, geological conditions also is not quite similar, and lightening activity is frequent, must strictly protect existing common insulator and lead.Pin insulator, Compound wire drawing insulator, post insulator structure are necessary to improve in the distribution at present; Its performance has much room for improvement; Each power supply department is to strengthening electric power netting safe running; Improve power supply reliability, the frequent broken string accident that is caused that prevents to be struck by lightning has become the problem that present power grid security presses for solution.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of collection to set up the lead function, lightning protection function and do not destroy the acupuncture conducting function of wire insulation, three kinds of external series gap lightning protection devices that function is an one.
A kind of external series gap lightning protection device comprises tight fixed bolt, acupuncture wire clamp, silicon rubber insulation umbrella, interior insulating cylinder; It is characterized in that the top gold utensil is provided with pressure regulatory element and conductive strips, zinc oxide resistance sheet, interior sparking electrode, insulation cushion, outer discharging gap rod, outer discharging gap sheath is equipped with on promptly outer sparking electrode, gold utensil screw thread top, lower end; Outer discharging gap rod shape is sagging; Inwardly curved, echo with outer discharging gap sheath, in order to discharge; Outer discharging gap rod protects with silicone rubber sleeve; The gold utensil bottom is provided with elastic washer and clamp nut in the bottom, compresses outer discharging gap rod sheath, closely is connected with mounting bracket, is convenient to accomplish discharge process.
Advantage of the present invention is: 1. the overvoltage process acupuncture wire clamp, pressure regulatory element, zinc oxide resistance sheet, interior sparking electrode, the outwards discharging gap sheath discharge of outer discharging gap rod that produce when thunderbolt; Minimum residual voltage is introduced the earth, accomplish protection process power equipment; 2. conservation of power cost of investment, non-maintaining or reduce maintenance workload, reduce maintenance cost; 3. do not receive climatic environment (like rain, snow etc.) influence, not influenced by air pollution and geological conditions; 4. because long service life is not deteriorated in the application in gap to zinc oxide resistance sheet; 5. employing silastic material, product is light, good insulation preformance, creepage distance is big, and it is convenient to construct, and can alleviate installer's labour intensity; 6. security of operation, stable, reliable.
Improved the lightning withstand level of circuit, created the investment little, income is big, and is non-maintaining, effectively protects probability and can reach the good result more than 98%.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Have among the figure: tight fixed bolt 1, acupuncture wire clamp 2, top gold utensil 3, pressure regulatory element and conductive strips 4, zinc oxide resistance sheet 5, silicon rubber insulation umbrella 6, interior sparking electrode 7, outer discharging gap rod 8, insulation cushion 9, interior insulating cylinder 10, bottom gold utensil 11, outer discharging gap sheath 12.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
As shown in Figure 1; Tight fixed bolt 1 is connected with acupuncture wire clamp 2; Top gold utensil 3, silicon rubber insulation umbrella 6, interior insulating cylinder 10, bottom gold utensil 11 are prior art, and pressure regulatory element and conductive strips 4, zinc oxide resistance sheet 5, interior sparking electrode 7, outer discharging gap rod 8, insulation cushion 9, outer discharging gap sheath 12 are present technique invention structural member.Zinc oxide resistance sheet 5 assemblies resistance electrical property is good, and the conductive strips on pressure regulatory element and the conductive strips 4 adopt the silver-plated material of copper alloy, and electric conductivity is fabulous; Interior sparking electrode 7, outer discharging gap rod 8 adopt conductive materials; Zinc oxide resistance sheet 5 adopts zinc oxide composite, when circuit is subjected to lightning impulse, causes overvoltage or forms power-frequency overvoltage when reaching the critical point of insulator arc-over; Acupuncture wire clamp 2 through the lightning protection device upper end; Electric current imports zinc oxide resistance sheet 5 and interior sparking electrode 7, and through outer discharging gap rod 8, externally discharging gap sheath 12 carries out gap discharge.Become the action of current limliting original paper, external discharging gap discharge is pressed the introducing the earth with remaining light current, guarantees that circuit normally moves.Employing is connected with the spring washer, the hex nut that compress outer discharging gap sheath 12 and combines with bottom gold utensil 11, and protection bottom gold utensil 11 is avoided electric arc burn, has improved the useful life of product.
