Method for influencing the extinctive capacity of follow-up current of overvoltage arresters and overvoltage arresters using this method

摘要

The control method is used for an overvoltage diverter device having a pair of spaced electrodes (2a,2b) contained within a housing (6) which contains an arc extinction gas, the volume of the interior (1) of the housing matched to the size of the arc current, to obtain a short-term increase in the internal pressure as a result of the arc current between the electrodes. The internal pressure may increase to between 10 and 60 bar, the overvoltage diverter device provided as a module inserted in an outer housing receiving one or more overvoltage diverter devices.
