GROUND SYSTEM FOR HIGH VOLTAGE SEMICONDUCTOR VALVE

摘要

A high voltage valve arrangement (l) comprising a high voltage valve unit (2); an external electric shield structure (6) arranged at least partially around the high voltage modular valve unit (2) and a grounding system (4). The grounding system comprising an grounding system (12) configured to be remotely extended from a retracted position (W) to an extended position (E), whereby the extendable grounding device establishes electric connection with the external shield structure when it is extended from the retracted position (W).
