Description

The invention relates to electric lighting devices and can be used in the electric power industry for marking the wires of high-voltage power lines in order to ensure the safety of aircraft flights near high-voltage power lines. One type of light marker for visualizing the position of high-voltage power lines is a special light ball, such as the patents mentioned below. These are: British Patent GB 2232474A (GB 2232474A, “An Illuminated aerial marker” F21Q 3/00, published 12/12/1990) the design of which is a ball with gas-discharge lamps located on the surface of the ball, the ball is fixed to the phase wire; the lamps are powered by taking capacitive current from the power line. A similar design is patented in the USA (Patent No. US4839567, “Illuminated aerial marker”, published 06/13/1989); A lighted overhead marker for a high-voltage power line, described in Russian Federation Patent No. 2556702 (Russian Federation Patent No. 2556702. Lighted Marker for an Overhead Power Line. F21S 8/00, published July 20, 2015, Bulletin No. 20). It differs from previously mentioned analogs in that it uses LEDs as the light source. Power is also supplied by drawing capacitive current from the power line through a dedicated voltage converter. The design of such devices differs from the design of systems using gas-discharge lamps with a cylindrical housing, therefore, design solutions for mounting gas-discharge lamps or LED strips in spherical markers cannot be applied to gas-discharge lamps with a cylindrical housing. Patents such as "Gas-discharge lamp" (RU Patent No. 2697189, "Gas-discharge lamp", H01J 61/02, published on 13.08.2019, Bulletin No. 23), "Gas-discharge lamp" (RU Patent No. 2746 31, "Gas-discharge lamp", H01J 61/02, published on 07.04.2021, Bulletin No. 10) specifically state the design of the lamps and their parameters and do not cover devices for attaching the lamp to the phase wire. An example of a design that utilizes a cylindrical gas-discharge lamp is the device described in Russian Federation Patent No. 2692056, "Device for Lighting Overhead Power Lines" (Russian Federation Patent No. 2692056, F21S 8/00, published June 20, 2019, Bulletin No. 17). A distinctive feature of this patent is the use of a specially designed shunt—a flexible metal cable made from wire spirals, with a winding pitch matched to the diameter of the line's phase conductor. The material from which this metal cable is made is not specified in the patent description, nor are any of its other parameters. A similar design is found in the well-known industrially produced light barrier system from OBSTA, which uses a BALISOR® neon gas-discharge lamp (OBSTA. Light Barrier Systems. Edition 6, 2019, 60 p.). The system also consists of a neon gas-discharge lamp, an antenna, and mounting elements—a lamp hanger, a shunt, insulators, and clamps. A structurally similar system is the high-voltage power line warning light system described in the Russian Federation Patent for Invention, "High-Voltage Power Line Warning Lighting Device" No. 2710204 (RF Patent No. 2710204, "High-Voltage Power Line Warning Lighting Device," F21S 8/00, Published: 25.12.2019, Bulletin No. 36). This system also consists of a neon gas-discharge lamp, an antenna, insulators, shunts, and fastening elements. The lamp is suspended by a cable, the material, and parameters of which are not specified. In fact, the above-mentioned designs utilized steel cables, the disadvantage of which is the occurrence of metal fatigue during repeated bending, leading to the destruction of the suspension structure under the influence of vibrations. The prototype chosen is the high-voltage power transmission line light barrier system described in Russian Federation Patent No. 2720886 ("High-voltage Power Transmission Line Light Barrier System", Russian Federation Patent No. 2720886, IPC F21/S 8/06, published on May 13, 2020 in Bulletin No. 14). The prototype high-voltage power transmission line light barrier system consists of a neon gas-discharge lamp, an antenna, insulators, shunts, and fastening elements, characterized in that the gas-discharge lamp is manufactured without a resistive ballast in the form of a glass spiral tube with a discharge channel with a diameter of 4 mm and a length of approximately 4 m in a protective shell made of quartz glass with a diameter of 50 to 60 mm, the operating pressure of neon in the lamp is selected within 3...5 mm Hg. Art., argon - approximately 0.04 mm Hg, the area of the lamp cathode is approximately 8000 sq. mm, the length of the antenna is selected as 3 m - for the power transmission line of 500 kV and 330 kV, 5 m - for the line at 220 kV, 10 m - for the line at 110 kV, the distance from the antenna to the phase wire is from 400 to 700 mm, the operating point of the lamp is selected on the branch of the volt-ampere characteristic with a negative differential resistance from 10 to 100 kOhm.
