Abstract
1414715 Arcing preventing ALLMANNA SVENSKA ELEKTRISKA AB 20 March 1973 [21 March 1972] 13218/73 Heading H1N In an arrangement for interrupting high voltage direct current comprising two switching devices 1, 5 connected in series and a capacitor 2 and a series connected spark gap 3 in parallel with the device 1, a surge diverter 4 is connected in parallel with the capacitor and spark gap or with the capacitor, the surge diverter being of the type having a plurality of parallel connected branches comprising non-linear resistors and spark gaps with magnetic blow-out coils and impedances arranged between the branches such as is described in Specification 1,193,558. The surge diverter 4 interrupts the current when the device 1 is opened and the device 5 provides voltage isolation. The switching device 1 may be a low-oil-content circuit-breaker and the device 5 may be a high-speed isolator.
