Description

(54) УСТРОЙСТВО ДЛЯ ГАШЕНИЯ МАГНИТНОГО ПОЛЯ(54) DEVICE FOR EXTINGUISHING A MAGNETIC FIELD

И ЗАЩИТЫ ОТ ПЕРЕНАПРЯЖЕНИЙ ЭЛЕКТРИЧЕСКИХ МАШИНAND PROTECTION AGAINST OVERVOLTAGE ELECTRIC MACHINES

. .,-.;. ., - .;

-.,.    -.,.

Устройство работает следуюшим образом . При гашении, магнитного пол  подаетс  сигнал на отключение коммутационного аппарата 3. При вхождении дуги в его дугогасительное устройство напр жение коммутационного аппарата возрастает до уровн  срабатьшани  разр дника, Последний срабатывает и замьшает цепь обмотки на защитный резистор 5, после чего происходит разр д обмотки возбуждени  на peзиcтop Коммутационный аппарат размыкает цепь возбуждени  с малой посто нной времени, т.е. с малым количеством энергии, выдел емой в его дугогасительном устройстве.The device works as follows. When damping, the magnetic field is given a signal to turn off the switching device 3. When an arc enters its arcing device, the voltage of the switching device rises to the level of the triggering of the arrester, the latter is triggered and short-circuits the winding on the protective resistor 5, after which the excitation winding is discharged to resistor The switching device opens the excitation circuit with a short time constant, i.e. with a small amount of energy released in its arcing device.

На фиг. 2 представлено устройство, в котором вместо разр дника 4 с одним разрывом и резистора 5 установлен разр дник с многократным разрывом 6.FIG. 2 shows a device in which, instead of the discharge 4 with one discontinuity and the resistor 5, there is installed a discharge with multiple discontinuity 6.
