When in use, the lightning-proof insulator can safely prevent the occurrence of lightning-caused breakage if the insulator is connected with the power transmission and distribution line in series through two ends and is tightly suspended on the line horizontally or vertically in relative to an electric pole. The lightning-proof suspension insulator has the advantages of simple structure, good use effect, and excellent economy and practicality.
Description
Technical field:
The utility model belongs to the electric power equipment that transmission of electricity distribution overhead wire is used.
A kind of can being used in the various power transmission and distribution voltage ranges, striking lightning voltage voluntarily prevents the lightning protection suspension insulator of lightning-caused breaking.
Background technology:
Known transmission of electricity power distribution circuit has all adopted insulated conductor, they have solved the safety problems such as electric current corridor that plain conductor originally has, but in actual use because lightning-caused breaking, the situation that makes whole electric line produce operation troubles happens occasionally, especially China's southern area, thunderstorm weather is often arranged, the meteorology that lightning flashes and thunder rumbles is more frequent, therefore the electric network fault that causes has accounted for 36.8% of whole line fault, and wherein the lightning-caused breaking rate has accounted for 96.8%, influenced the normal power supply of gauze greatly, also very considerable to the loss that national economy causes.Japan just once studied at early seventies and reached a conclusion: if insulated conductor does not have appropriate lightning protection measures, run into so when being struck by lightning more by force and will inevitably break.Therefore insulated conductor must be solved by the problem of lightning-caused breaking, the safe operation of overhead insulating transmission and distribution network could be guaranteed.Known method has the installation overhead ground wire, puncture property arc-preventing metal utensil, and zinc oxide arrester, pillar anti-thunder insulator or the like, but still exist various shortcomings and problem, need invention a kind of more effective, more convenient, more be adapted to the anti-thunder insulator of various installation situations.
Summary of the invention:
The purpose of this utility model: invent a kind of can being used in the various allocated transmission piezoelectric voltage scopes, striking lightning voltage voluntarily prevents the suspension type anti-thunder insulator of lightning-caused breaking.When circuit meets all size power frequency thunderbolt voltage, it is the striking lightning voltage voluntarily, flashover thunderbolt passage is provided at the insulator two ends, the arc root of power frequency arc of on the lightning stroke flashover passage, setting up or single-phase short circuit current, can only be fixed on the high-low pressure electrode that starting rod provides, thereby avoided the burn of insulator full skirt, even blown the phenomenon generation of insulated conductor.The technical solution of the utility model is such:
Left side at known compound suspension insulator 6; right two ends fixedly mount a starting rod 2 that has the globular discharge head respectively; starting rod 2 relies on starting rod briquetting 4 usefulness bolt and nut components 3; be fixed on the left end and the right-hand member of core rod of insulator 6; the core rod of insulator 6 of its left end is connected with the cable energising by bulb (or link plate) 1 in use; at this moment gone into high potential in the bulb, top of left end starting rod 2; and the other end; be that to get along well that any circuit connects be low-voltage to right-hand member; when using, insulator only is connected with the circuit tension by right-hand member socket-clevis eye 8 (or annular link plate); the utility model is suspended on the electric line; right-hand member at insulator is exactly an electronegative potential; at this moment on the left side of insulator; form an air gap between the high-low pressure electrode of right two ends; be mainly used to provide lightning stroke flashover passage and arc discharge passage; its operation voltage is lower than insulator body; and must make the thunder and lightning drainage prior to action before the insulator body flashover, protected insulator and lead.When the overhead insulating transmission and distribution network is subjected to direct stroke or induction lightening, the left and right two ends of insulator starting rod 2, the air gap that provides, can before insulator arc-over, action earlier discharge, the flashover passage of thunder and lightning is provided, the arc root of power frequency arc of on the lightning flash over passage, setting up or single-phase short circuit current, can only be fixed on the high-low pressure electrode that starting rod provides, do not go here and there on insulator body or the lead and can not flow, thereby avoided the burn of insulator full skirt, even blown the phenomenon generation of insulated conductor.
The utility model satisfies the line insulator of GB regulation and every specification requirement of gold utensil, insulator and arc-preventing metal utensil are united two into one, can hang tension on the allocated transmission electric line of any voltage swing, it can install with respect to electric pole in the level tension, also can vertically strain and be suspended on the line tower, have very big economy and practicality.The starting rod 2 that the utility model provides can provide repeatedly the ablation of power frequency arc, and dependable performance has good dynamic characteristic, can effectively prevent the generation of insulated conductor lightning-caused breaking accident.
