HIGH-VOLTAGE VACUUM SWITCH |
摘要 |
FIELD: electrical engineering, switching of A C power circuits. SUBSTANCE: high-voltage vacuum switch has three arc chutes with mobile contacts connected to driving device with the aid of kinematic circuit that includes dielectric tie-rods and flat parallel link mechanism made of rotary bell-cranks which rotation axles are linked to case via spring mechanisms f contact pressing. Symmetry axis of dielectric tie-rods and spring mechanisms of contact pressing are placed in one plane with link mechanism. First levers of rotary bell-cranks are interconnected with the use of two strips and second levers are hinged to dielectric tie- rods. Each rotary bell-crank has rest of second lever located between dielectric tie-rod and spring mechanism of contact pressing and two additional rests, one being positioned in symmetry with main rest and second one being arranged on axis of dielectric tie-rod. Driving device registers ON and OFF positions of switch and spring mechanism of contact pressing works in compression and extension. EFFECT: increased speed of response and decreased power of drive. 2 cl, 11 dwg
