Abstract
554,967. Gas - blast switches. AKT.-GES. BROWN, BOVERI & CIE. Sept. 5, 1942, No. 12558. Convention date, Sept. 27, 1941. Addition to 530,971. Drawings to Specification. [Class 38 (v)] The invention of the parent Specification is modified by providing a supplementary impedance means across each group of breaks so as to provide an initial coarse adjustment of voltage-distribution and enable smaller impedances for the individual breaks to be used. Condensers for coarse control and resistances for the individual breaks, or conversely, may be employed. The disconnect-switch contacts may be of the magnetic blow-out type.
