Abstract
Способ защиты ячеек комплектных распределительных устройств от дуговых замыканий, при котором измеряют токи в фазах кабеля ячейки, сравнивают их с первой эталонной величиной и через выдержку времени отключают выключатель кабеля, если эти токи, хотя бы в одной из фаз, больше первой эталонной величины, отличающийся тем, что дополнительно измеряют токи нулевой последовательности вблизи выводов выключателя и вблизи кабельной воронки со стороны кабеля, вычисляют разность между ними, сравнивают ее со второй эталонной величиной, и если эта разность больше второй эталонной величины, то отключают выключатель кабеля без выдержки времени.A method of protecting switchgear switchgear cells from arc faults, in which currents are measured in the phases of the cell cable, they are compared with the first reference value and after a time delay the cable switch is turned off if these currents, at least in one of the phases, are greater than the first reference value, differing the fact that additionally measure the zero sequence currents near the terminals of the switch and near the cable funnel on the cable side, calculate the difference between them, compare it with the second reference value, and if this time Since the value is larger than the second reference value, the cable switch is turned off without a time delay.
