HIGH-VOLTAGE VACUUM SWITCH Russian patent published in 1997 - IPC

FIELD: electric engineering, in particular, switching powerful high-frequency circuits without load. SUBSTANCE: electromagnet in switch is located in perpendicular to axis of its vacuum switching part so that electromagnet core modes in perpendicular to it in plane which contains direction of movement of movable contact when circuit is rendered conducting through fixed contacts. Mechanism for regulation of contact pressing is designed as two threaded sleeves, which are made from magnetically soft material, for example from low carbon steel. Said sleeves are located along same axis as center of bases of electromagnet housing and are mounted in coaxial to core on its opposite faces. EFFECT: increased functional capabilities. 4 cl, 3 dwg
