Abstract
Изобретение относитс к области электротехники. Цель изобретени - повышение эффективности ограничени токов и напр жений при коммутации путем снижени ударных токов и перенапр жений . Дл этого сначала включают выключатели 8 и 12. Резисторы 14-17 позвол ют снизить ударный ток. С выдержкой времени, осуществл емой блоком задержки 18, включают выключатели 7,9,10 и 11. При отключении сначала отключают выключатели 7 и 10, а затем с выдержкой времени блока задержки 20 - выключатели 8,12. Резисторы 16,17 уменьшают угол сдвига между током и напр жением, снижают напр жени на конденсаторах. После этого с выдержкой времени блока задержки 21 отключают выключатели 9 и 1 1. 1 ил. ё (ЛThis invention relates to the field of electrical engineering. The purpose of the invention is to increase the effectiveness of limiting currents and voltages during switching by reducing shock currents and overvoltages. To do this, switches 8 and 12 are first turned on. Resistors 14-17 can reduce the shock current. With a time delay carried out by the delay unit 18, the switches 7, 9, 10 and 11 are turned on. When disconnected, first turn off the switches 7 and 10, and then with the delay time of the delay unit 20, the switches 8.12. Resistors 16, 17 reduce the shear angle between current and voltage, and reduce the voltage across the capacitors. After that, with a delay of the delay unit 21, the switches 9 and 1 1 are turned off. 1 Il. ё (L
