Abstract
FIELD: electrical engineering. SUBSTANCE: D. C. contactor is fitted with device for arcless opening of main contact 2 thanks to shunting it with key thyristor 3 unbalanced at initial moment of break of contact with the aid of starting circuit composed of capacitor 9 and diode 10. Turn-off of thyristor 3 is provided by unit of forced communication including commutating thyristor 4 and capacitor 5. Capacitor 5 is changed with the help of changing circuit incorporating thyristor 6 and resistor 7. Thyristor 6 is controlled by network including resistor 17, capacitor 18 and limit switch 19 mechanically coupled to mobile part of contactor which are connected in series. EFFECT: enhanced functional reliability of contactor. 1 cl, 1 dwg
