FIELD: machine building.

SUBSTANCE: invention relates to generator setting devices, and more specifically to pulleys of isolating disconnector. Isolating disconnector comprises shaft, pulley installed on the shaft on bushing with low friction coefficient, spring holder, torsion spring connected between pulley and spring holder and spring overrunning one-way clutch. Coupling is arranged radially inside the torsion spring and around the shaft. Pulley is temporarily engaged with the end of spring overrunning one-way clutch in unwinding direction.

EFFECT: temporary contact between the end of coiled spring one-way clutch and pulley temporarily reduces friction engagement between coupling and shaft.
