OPERATING MECHANISM OF A HIGH-VOLTAGE MULTIPOLE SWITCH

摘要

13 OPERATING MECHANISM OF A HIGH-VOLTAGE MULTIPOLE SWITCH An operating mechanism (40) of a high-voltage switch comprises a first operating crank (52) coupled by a transmission rod (54) to a second operating crank (56), which is keyed onto an operating shaft (58) of the switch. A toggle (65), made up of a loading crank (66) articulated on a telescopic support guide (70) of an energy storage spring (72), cooperates with the two operating cranks (52, 56) to constitute a double-tumbler mechanism without latching. The loading crank (66) is driven by a transmission mechanism (88) controlled either automatically by a geared motor unit (90) or manually by a shaft (94) of an emergency control (44). Refer to figure 9.
