LIGHT PROTECTION SYSTEM OF HIGH-VOLTAGE POWER TRANSMISSION LINES Russian patent published in 2020 - IPC F21S8/06 

FIELD: lighting engineering.

SUBSTANCE: invention relates to electric lighting devices and can be used in electric power industry as protective lights of wires of high-voltage power transmission lines to ensure safety of flights in areas of aerodromes, air routes, as well as areas of surfaces rising above ground. Device comprises a gas-discharge neon lamp, an antenna, insulators, shunts and fasteners. Gas-discharge lamp is made in form of glass spiral tube with discharge channel with diameter of 4 mm with length of approximately 4 m in protective shell from quartz glass with diameter from 50 to 60 mm, working pressure of neon in the lamp is selected within range of 3…5 mm Hg, argon – approximately 0.04 mm Hg, the lamp cathode area is approximately 8000 mm², the antenna length is selected is 3 m – for 500 kV and 330 kV power transmission lines, 5 m – for 220 kV line, 10 m – for 110 kV line, the distance from the antenna to the phase wire is from 400 to 700 mm, the lamp working point is selected on the branches of the current-voltage characteristic with negative differential resistance from 10 to 100 kOhm.

EFFECT: technical result consists in reduction of power consumption of device with simultaneous increase in brightness of luminescence, increase of service life, reduction of dimensions and weight of device and simplification of design.
