Description
Магнитна система быстродействующего выключател 4 (фиг. 3) состоит из магиитоировода 24 с удерживающей катушкой 25 и магиитиыми винтами 26 и 27 дл регулировки уставки. На раз1магничивающем мостике 28 расположены отключающа катушка 2 и дополнительна отключающа катушка 3, магнитные потоки которых направлены согласно. Магнитные наконечники 29 и 30 удерживают подвижный рычаг 31, соединенный с силовыми контактами 1. Отключение выключател 4 осуществл етс пружиной 32.The magnetic system of the quick-acting switch 4 (FIG. 3) consists of a magneto-conductor 24 with a holding coil 25 and magical screws 26 and 27 for adjusting the set point. A disconnecting coil 2 and an additional disconnecting coil 3 are located on the demagnetizing bridge 28 and their magnetic fluxes are directed according to. Magnetic lugs 29 and 30 hold the movable lever 31 connected to the power contacts 1. The switch 4 is turned off by the spring 32.
Устройство работает следующим образом .The device works as follows.
При коротком замыкании в цепи нагрузки происходит нарастание токов в отключающей катушке 2 и дополнительной отключающей катушке 3. При этом ток в цепи реактора, а следовательно, в отключающей катущке 2 нарастает сравнительно медленно, а в цепи дополнительной отключающей катушки 3 быстро (фиг. 2), поскольку замыкание нагрузки соответствует замыканию конденсатора 8. За счет броска тока в дополнительной отключающей катушке 3 существенно ускор етс отключение быстродействующего выключател 4. В то же вр/ем катушка 3 не вли ет на статическую уставку быстродействующего выключател 4, так как в нормальных рабочих услови х по ценп дополнительной отключающей катушки 3 течет переменный ток частотой 800 Гц, среднее значение которого равно пулю. Поэтому регулированиеDuring a short circuit in the load circuit, there is an increase in the currents in the tripping coil 2 and additional tripping coil 3. In this case, the current in the reactor circuit and, therefore, in the tripping coil 2 increases relatively slowly, and in the additional tripping coil 3 quickly (Fig. 2) Since the load closure corresponds to the closure of the capacitor 8. Due to the inrush current in the additional disconnecting coil 3, the disconnection of the fast-acting switch 4 is significantly accelerated. At the same time, the coil 3 does not affect the static setting the high speed circuit breaker 4, as in normal operating conditions of Tsenpo additional trip coil 3 flows an alternating current frequency of 800 Hz, the mean value is equal to zero. Therefore regulation
