Embodiment Construction

[0020] figure 1 A first embodiment of a lightning arrester according to the invention is shown. The lightning arrester for lightning protection of components of electronic equipment or power transmission lines is manufactured in the form of a corona ring for leveling the Electric field strength. The arrester is generally manufactured from a hard dielectric, as is the insulating body 2, which is configured to be mechanically attached to said or adjacent elements of an electronic device or power transmission line. Attachment can be done in various ways, for example, by the shape of the insulative body at the point of attachment (eg, rectilinear shape, curved shape, circular shape, helical shape, etc.). Furthermore, the insulative body may have protrusions / depressions / holes etc. for providing attachment where mating fasteners or mating components of components of electronic equipment or power lines are used. exist figure 1 In the particular embodiment shown, the lightning arr...

Abstract

Proposed is a discharging screen for the lightning protection of components of an electrical system or transmission line and the equalization of an electric field. The discharging screen comprises an insulating body designed for mechanical attachment to a component of an electrical system or transmission line. The insulating body has a shape which enables it to bend at least partially around the aforesaid component of an electrical system or transmission line with the formation of an air gap between the insulating body and the component of an electrical system or transmission line. Mechanically connected to the insulating body are two main electrodes and two or more intermediate electrodes, which are situated between the main electrodes such that a discharge can be generated between the main electrodes and the intermediate electrodes adjacent thereto and between adjacent intermediate electrodes.

Description

technical field [0001] The present invention relates to protective accessories mounted on electronic equipment, especially on insulators and insulator strings, for arc and / or corona discharge protection, and / or for leveling on insulators or insulator strings voltage distribution. Furthermore, the invention relates to a lightning arrester for lightning overvoltage protection of electronic equipment. Such devices may provide protection for high voltage installations, insulators and other power transmission lines, and components of electronic equipment. Background technique [0002] International application WO2010082861 discloses a lightning arrester for protecting components of electronic equipment or power lines, comprising an insulating body, two main electrodes and two or more intermediate electrodes, the insulating body being configured for mechanical attachment To an element of an electronic device or power line, the two main electrodes are mechanically coupled to an i...
