Abstract
Abstract A corona-discharge electrode system, especially for electrostatic precipitators and similar devices for the electrostatic separation of particles from a fluid stream, wherein the electrodes are secured to an upper carrying structure and a lower spacing structure. The electrodes, which are suspended from the upper structure, positively engage the same, e.g., via hooks, eyes or a clamping connection. Tensioning weights of a nonconducting material, preferably waterproof concrete, are removably secured to the lower ends of the electrodes and are provided with openings adapted to receive the spacing structure.
