The high-voltage line lightning arrester can release static electricity collected on lines continuously, avoid lightning stroke, is simple and practical and has low manufacturing and maintenance cost.
Description
Technical field
The utility model relates to transmission line guard technology field, is a kind of high-tension line lightning arrester that prevents the overhead transmission line indirect lightning strike concretely.
Background technology
Aerial high-voltage power transmission line, built on stilts civil power conveying circuit, built on stilts communication line often damage owing to indirect lightning strike causes line interruption or equipment.The method that prevents indirect lightning strike at present mainly contains two kinds: a class is to adopt on piezo-resistance or gas discharge tube parallel connection and the circuit; Another kind of is the mode that adopts electronic current limiter.They all are by linking to each other with the earth, constitute a current drain path, be used for reducing the amplitude and the shunting induction lightening electric current of induced voltage, reaching the purpose that prevents indirect lightning strike.But the method for these two kinds of lightning protection has significant limitation.At first, it can't change formation and the accumulation on the line of a large amount of charge inducings, and forms the very big indirect lightning strike of damaging range during being deposited in thunder and lightning and producing of this charge inducing easily; Secondly, because piezo-resistance and poor, the delay of response of gas discharge tube shunting effect often cause lightning protection to lose efficacy, and the anti-strong indirect lightning strike ability of electronic current limiter often cause the components from being damaged of electronic current limiter own, has reduced the useful life of lightning arrester.
The utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of and can reasonably the circuit stored charge have been discharged and long-lived high-tension line lightning arrester.
For realizing above-mentioned technical problem, the utility model is achieved through the following technical solutions: a kind of high-tension line lightning arrester, comprise the needle unit on ceramic package, top, the poly-electric spheroid of needle unit bottom connection and the fixed mount of ceramic package bottom, it is characterized in that poly-electric spheroid connects obstructing instrument by defeated thunder lead, obstructing instrument is embedded in underground earthing conductor by the lead wire and earth wire connection, needle unit connects transmission line by electrostatic conductor, is provided with piezo-resistance in the middle of the electrostatic conductor.
Above-mentioned described obstructing instrument is made up of two metallic plates and insulation crust, and two metallic plate symmetries are respectively equipped with some pointed projectioies on the relative one side, and pointed protruding spacing keeps 0.5 millimeter on two metallic plates.
According to electrical principles, the electric charge that outstanding part is assembled is many more, so when charge number is punctured by electric charge and forms path in the space between two metallic plates when reaching considerable, under the usual state, obstructing instrument is under the off state, alternating current can not enter ground by lead wire and earth wire, form a path by electrostatic conductor between the needle unit of the utility model in transmission line and lightning arrester, static on the transmission line is when reaching some, just flow to spicule along electrostatic conductor, and on poly-electric spheroid, store, according to the principle of electricity upper prong discharge, the electric charge in the poly-electric spheroid progressively is discharged into the external world by needle unit.
The beneficial effects of the utility model are: can constantly the static of assembling on the circuit be discharged, avoid causing thunderbolt, the centre is provided with obstructing instrument can intercept that to carry alternating current to import underground, forming path when thunder and lightning attacks can import thunder and lightning underground smoothly, this device is simple and practical, and cost and maintenance cost are low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure chart of obstructing instrument in the utility model.
Among the figure, 1, needle unit, 2, poly-electric spheroid, 3, defeated thunder lead, 4, electrostatic conductor, 5, obstructing instrument, 6 ceramic packages, 7, piezo-resistance, 8, fixed mount, 9, lead wire and earth wire, 10, insulation crust, 11, pointed projection, 12, metallic plate.
Embodiment
With reference to accompanying drawing 1, needle unit 1 has the metal material that conducts electricity very well to make, and its underpart is provided with poly-electric spheroid 2, and poly-electric spheroid 2 is made by metal material, and its effect is with Charge Storage; The lower end of needle unit 1 connects obstructing instrument 5 by defeated thunder lead 3, and obstructing instrument 5 is embedded in underground earth electrode by lead wire and earth wire 9 connections; Transmission line 13 is connected the lower end of spicule 1 by electrostatic conductor 4, its effect is to transfer to the electrostatic charge that transmission line 13 is assembled on the needle unit 1 and be stored in to gather in the electric spheroid 2, principle according to the discharge of electricity upper prong, the electric charge of assembling will be by needle unit 1 discharging progressively, electrostatic conductor 4 is divided into two sections, two sections by piezo-resistance 7 connections, piezo-resistance 7 effects are the static on the transmission line 13 can be transferred on the needle unit 1 smoothly, and thunder and lightning reaches on the transmission line 13 along electrostatic conductor when preventing thunderstorm, above-described parts are sealed in the ceramic package 6, prevent the corrosion of rainwater, the bottom of ceramic package 6 is connected on the fixed head 8, and whole device is placed on the iron tower or other high things that is higher than transmission line 13 by fixed head 8.
With reference to Fig. 2, obstructing instrument 5 is made up of two symmetrical metallic plates 12 and insulation crust 10, two metallic plate 12 parallel placements, relative one side is respectively equipped with pointed protruding 11 of some correspondences, distance on two metallic plates 12 between pointed protruding 11 remain on 0.5 millimeter with interior but the contact, then two metallic plates 12 are fixed together by insulation crust 10, two metallic plates 12 connect defeated thunder lead 3 and lead wire and earth wire 9 respectively, according to the structure of obstructing instrument 5 as can be seen, the moment that a large amount of electric charges are assembled on obstructing instrument 12 when thunder is attacked, the electric charge major part accumulates on pointed protruding 11, this moment, electric charge can puncture the space between two plates, form path, thunder and lightning is caused underground by lead wire and earth wire 9, when normal condition, electrostatic charge is not too much assembled, this moment, obstructing instrument 5 was in off state, prevented that the alternating current in the transmission line 13 from passing to underground.
