Device for tensioning corona-discharge electrode elements

摘要

The wires or strips (corona-discharge electrode elements) of a corona-discharge electrode are tensioned in the support frame thereof by anchoring one end of each element to a bar of the frame, drawing the other element with a predetermined tension by fluid pressure toward an opposite bar of the frame, and anchoring the latter end to this bar. The tool for tensioning the element comprises a caliper or C-shaped member, one arm of which is provided with a fluid cylinder whose piston bears against the latter bar, and means on at least one arm of the caliber engaging the electrode wire or strip. Preferably the arm opposite that on which the cylinder is provided has means for engaging or guiding the electrode element.
