Tasks
In the Schwandorf waste recycling plant, the previous 6 kV MS-AIS switchboard was replaced by a 6 kV MS-GIS switchboard corresponding to the state-of-the-art. The 6kV MS-AIS switchboard comprised a single busbar and was connected via a longitudinal coupling. Furthermore, it served for feeding seven LV switchboards, two induced draught fans, one secondary fan and one feed water pump.
The switchboard was replaced by a DSS system and installed as a SF6 gas-insulated switchboard. The modern 6 kV MS-GIS switchboard was set up during ongoing operation of the existing system. The connection to the control system is realized via an IEC 61850 interface, using SICAM devices.
