MULTIELECTRODE CORONA RING-ARRESTER

摘要

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.
