MULTI-CHAMBER DISCHARGER, HIGH-VOLTAGE INSULATOR WITH MULTICHAMBER DISCHARGER AND HIGH-VOLTAGE POWER TRANSMISSION LINE USING SUCH INSULATOR

摘要

FIELD: electricity.SUBSTANCE: discharger for lightning protection of elements of electrical equipment or a power transmission line comprises an insulating body (1) and a multi-electrode system comprising at least five electrodes (2). Electrodes (2) are mechanically connected with the insulating body (1) and are arranged inside the body (1) with the possibility to form an electric discharge between adjacent electrodes under action of lightning overvoltage. Electrodes (2) exit into discharge chambers (3). Several discharge chambers (3) consist of two joined parts, besides, first parts of discharge chambers (3), where electrodes enter (2), are arranged in the form of holes (4) in the body (1), and the second parts of discharge chambers (3), connected to the first parts are arranged in the form of slots (5), reaching the surface of the body (1).EFFECT: increased efficiency of lightning protection due to reduction of probability of combining separate torches of arcs of follow current into a single channel.14 cl, 6 dwg
