HEAVY-CURRENT FAST-ACTION REVERSIBLE SWITCHING DEVICE Russian patent published in 1997 - IPC

FIELD: electrical engineering, pulse supply systems of electrophysical installations. SUBSTANCE: mobile bridge contacts are manufactured in the form of rollers self-set between immobile contacts in each of two stable positions of mobile system. Immobile contacts form with additionally inserted contacts four pairs of contacts insulated one from another. In each of two possible stable positions of mobile system two pairs of immobile current leads are closed by spring-loaded roller contacts. Spring-loaded sliding supports rest against cross-pieces via ball bearings. Mobile casing enclosing spring-loaded sliding supports is made from insulation and rotates about axis in two bearings. Two pairs of pulse coils are used to act on mobile casing. EFFECT: enhanced reliability and safety of switching device. 1 dwg
