Abstract
The utility model relates to a device for a high voltage transmission line, and especially relates to a puncture type lightning protection composite insulator. The puncture type lightning protection composite insulator comprises a puncture electrode, a pressing line plate and a lower fitting, wherein the puncture electrode and the pressing line plate are mated with each other. The wire guiding groove of the puncture electrode is provided with tooth-shaped puncture tooth which is used for puncturing a lead insulating layer for electrical connection. The whole electrified portion of the puncture electrode is wrapped by an insulating shield. A discharging gap device, an aluminium pad and a metal oxide resistance sheet, which are close to each other, are successively arranged between the lower end of the puncture electrode and the upper end of the lower fitting. The lower end of the puncture electrode is tightly contacted with the upper end of the discharging gap device. The lower end of the metal oxide resistance sheet is tightly contacted with the upper end of the lower fitting. The portion between the bottom of the puncture electrode and the top of the lower fitting is entirely wrapped by a laid band layer. An insulating umbrella cover is wrapped outside the laid band layer. The puncture type lightning protection composite insulator exhibits a fine lightning protection function and a fine electric contact performance, is high in mechanical strength, wide in application range and long in service life.
Description
Technical field
The utility model relates to a kind of equipment that is used for ultra-high-tension power transmission line, refers in particular to a kind of penetration type lightning protection composite insulator.
Background technology
Insulator is applied to (high type) high-tension bus-bar connecting rod (tower); In overhead transmission line, play two basic roles---fixing cord with prevent that electric current from going back to ground; These two effects must be guaranteed; Insulator should be owing to environment and the electric loading condition various dynamo-electric stress that causes that changes lose efficacy, otherwise insulator has just lost its effect, will damage the safe handling and the service life of transmission line.Along with the overhead transmission line insulating is transformed, the insulator circuit of traditional design, therefore the effect that is difficult to bear direct thunder or induction thunder, must be designed and have the insulator of lightning protection function preferably.
The utility model content
The technical problem that the utility model will solve is: provide a kind of have good lightning protection function, simultaneously possess good electrical contact performance, hydrophobicity performance, ageing resistace, electric erosion resistance can and the penetration type lightning protection composite insulator of all insulation of higher mechanical strength.
The utility model solves the technical scheme that its technical problem adopted: a kind of penetration type lightning protection composite insulator; Include the penetrating electrodes and the tension disc that tighten up cooperation through bolt and nut; And lower end gold utensil; In the crossed beam trunking of penetrating electrodes, be provided with and be used to pierce through the thread form puncture tooth that wire insulation is electrically connected with formation, whole charged position is wrapped up by insulating shield, from the lower end of penetrating electrodes to adjacent successively discharging gap device, aluminium backing and the metal oxide resistance of being provided with the upper end of lower end gold utensil; The lower end of penetrating electrodes closely contacts with the upper end of discharging gap device; The lower end of metal oxide resistance closely contacts with the upper end of lower end gold utensil, wraps up to the integral body of the part the top of lower end gold utensil from the bottom of penetrating electrodes having or not the latitude belt, outside no latitude belt, wraps up in and is with the insulation umbrella cover.This penetration type lightning protection composite insulator is after installation is come into operation; Under normal condition; The gap of the discharging gap device in the insulator isolates metal oxide resistance and system and is under the lower electric field; Do not participate in the lightning protection operation, thereby prolonged the useful life of metal oxide resistance; When the voltage that surpasses regulation occurs, the discharge of discharging gap flashover, metal oxide resistance participation work discharges overvoltage.
Described metal oxide resistance adopts the very excellent zinc oxide resistance sheet of non-linear volt-ampere characteristic.
Described insulation umbrella cover is the high-temperature silicon disulfide rubber umbrella cover with good hydrophobicity performance, ageing resistace and electric erosion resistance ability.
Described insulated umbrella Analysis of Nested Design becomes big or small full skirt overlapping formula structure, to improve the anti-pollution flashover ability of umbrella cover to transmission line.
The beneficial effect of the utility model is: this penetration type lightning protection composite insulator has good lightning protection function; And possess good electrical contact performance, hydrophobicity performance, ageing resistace, electric erosion resistance can and higher mechanical strength; The product all insulation; Easy for installation, applied widely, long service life.
