A kind of strain insulator-string parallel clearance lightning protection device
Technical field
The utility model relates to Lightning Protection on Power Transmission Lines technical field, in particular to a kind of strain insulator-string parallel clearance lightning protection device.
Background technology
At present, the fault caused by thunder and lightning in electrical network comprises lightning stroke flashover and power frequency continued flow, is the principal element affecting electric power netting safe running, can damages insulator and gold utensil etc. thereof, especially the insulator well damage at insulator string both ends.
The existing lightning protection measures of overhead transmission line has erection lightning conducter, reduces pole tower ground resistance, reinforced insulation, installs coupling ground wire additional, installs Transmission Line Arrestor etc., and its core concept improves lightning withstand level and the minimizing tripping rate with lightning strike of circuit as much as possible.Since reform and opening-up, China's electrical network is fast-developing, and grid structure is more and more stronger; Transformer station also uses SF6 switch in a large number, relaying protection Microcomputer, and reclosing device obtains and generally applies.Pass through the typical meteorological characteristic sum Crack cause having investigated a large amount of line insulator lightning stroke flashovers, my company is necessary lead-in insulator connection in series-parallel clearance lightning-proof device, optimal design parallel connection gaps.
Utility model content
The purpose of this utility model is to provide a kind of strain insulator-string parallel clearance lightning protection device formed in insulator string two ends correspondence, and to reach good lightning protection effect, structure is simple, easy for installation.
For realizing the utility model object, the technical scheme of employing is: a kind of strain insulator-string parallel clearance lightning protection device, comprises left trick arc ring and right trick arc ring; In the form of a ring, and right trick arc ring is obliquely installed described right trick arc ring outside insulator string; Described left trick arc ring comprises arcing horn, and the end of arcing horn in the form of a ring.
Further, the end ring-type of described arcing horn is closed circular, and arcing horn is corresponding with right trick arc ring.
Further, described arcing horn is two of laying respectively on two insulator strings, and two arcing horns are positioned at the same side of insulator string.
Further, the low side of described right trick arc ring is provided with gap.
Further, the low side of described right trick arc ring is provided with strutting piece, and strutting piece is connected with mounting panel.
The beneficial effects of the utility model are:
1, in parallel with insulator string by left and right trick arc ring, make thunder and lightning along gap discharge, dredge power frequency arc, protection insulator avoids burn, and this Lightning Protection is that the strong of conventional transmission lines road Lighting Protection Measures supplements.
2, power frequency arc is drawn and is blown out by this device in the duration of short circuit allowed, considerably reduce the rate of failure that circuit causes due to thunderbolt or pollution flashover, and improve the shape of insulator string two end electrodes to a certain extent, make the voltage's distribiuting of insulator string have mild trend.
3, in the wave head time range that lightning impulse may occur, the lightning impulse discharge path of parallel connection clearance device is the air gap between electrode, and this enables the power frequency continued flow produced subsequently away from insulator string.Lightning protection device structure of the present utility model is simple, easy for installation, is suitable for engineer applied, serves the effect of well protection insulator.
