Abstract
FIELD: electric engineering. SUBSTANCE: device has two power contacts 1 and 2 which are connected in series and are by-passed by main thyristor 4. Contact 2 is also by-passed by non-linear resistor 3, which is connected to control junction of thyristor 4. Contact 2 switches off firstly, this causes unlocking of thyristor 4, then contact 1 switches off. After switching off of power contacts 1 and 2, thyristor 4 is locked by means of unit of forced commutation (which consists of elements 6, 7, 8, 9). Latter unit is switched on after closing of end switch contacts 17 which supplies positive potential from preliminary charged capacitor 7 to control electrode of thyristor 6 through stabilizing diode 14, resistor 15 and diode 16. Said capacitor 7 is charged by power supply 5 through resistor 11 and thyristor 10, which is controlled by serial circuit of elements 18, 19, 20. EFFECT: increased functional capabilities. 3 cl, 1 dwg
