Abstract

613,433. Switchgear structures. NAAMLOOZE VENNOOTSCHAP FABRIEK VAN ELECTRISCHE APPARATEN VOORHEEN F. HAZEMEIJER & CO. Nov. 16, 1945, No. 30730. Convention date, Nov. 2, 1942. Addition to 611,229. Drawings to Specification. [Class 38 (v)] The invention of the parent Specification is modified by replacing the compressed-gas power-switches by thyratron gas-discharge tubes, the series break isolating switch operatively associated with this power switch being opened automatically after the power switch opens. The invention is described in detail in its application to the arrangements shown in Figs. 4 and 9 of that Specification.
