SWITCHING DEVICE |
摘要 |
FIELD: low-voltage electrical equipment; arcless switching of circuits with inductive energy storages. SUBSTANCE: device has power contact 1 shorted out by circuit set up of n series-connected auxiliary contacts 2 and 3 of which (n-1) auxiliary contacts 2 are shorted out by nonlinear resistance units 4 and inductive load 5 is shorted out by circuit of series-connected backward diode 6 and nonlinear resistance unit 7 whose leads are connected to interlocking contact 8 and primary winding of pulse transformer; secondary winding of the latter is connected through backward diode 10 to leads of power supply 11. EFFECT: provision for arcless switching and return of energy stored in magnetic field of load inductance coil to power supply. 2 cl, 2 dwg øøø1
