  • sf 6 switch electrical equipment for High Speed Rail

    The high-speed rail power topology developed by Alstom [73] is shown in Fig. 9.39 for use with the 15-kV, 16.67-Hz AC power line. Eight cascaded 6.5-kV IGBT modules are used on the line side to convert the 16.67 Hz input frequency to 5 kHz.This reduces the size and weight of the transformer while keeping the switching power losses at a

    As SF6 decomposes during arcing metal fluorides are created, which are corrosive. When servicing SF6 breakers that have been faulted, full body protection and oxygenfed respirators may be needed to prevent the fluorides from contacting the skin or being inhaled. Any moisture on or in the body will create hydrofluoric acid.
