A DEVICE FOR SUPERVISING IN A HIGH VOLTAGE CONVERTER STATION
摘要
A device for supervising the cooling of a cooling system of a valve of a high voltage converter station located on high voltage potential level comprises members (31) located on high voltage potential level and adapted to detect the temperature at cooling blocks (32) of the valve on high voltage potential level and send values so detected to first control units (3) for controlling semiconductor components (4) of the valve. The first control units have means (20) for treating said values detected and the first control units are adapted to send data resulting from said treatment to an arrangement (16) for supervising said valve located on low potential level.
