Description
ключател подключены диод 21 и сопротивление 22. Фазы 23, 24, 25 источника питани подключены к фазоконтрольному блоку через предохранители 26, 27, 28.the switch is connected to a diode 21 and a resistance 22. The power supply phases 23, 24, 25 are connected to the phase-control unit via fuses 26, 27, 28.
Устройство работает следующим образом.The device works as follows.
Дл срабатывани срелочного привода 1 поворачивают стрелочную руко тку, и через контакт 9.3 пол ризованного пускового релеTo operate the spindle drive 1, turn the dial knob, and through pin 9.3 of the polarized start relay
9возбуждаетс нейтральное пусковое реле9excited neutral starting relay
10с проверкой необходимых зависимостей, выполн емой контактом 12 реле проверки зависимостей.10c by checking the required dependencies performed by pin 12 of the dependency check relay.
Реле 10 контактом 10.6 замыкает цепь возбуждени пол ризованного пускового реле 9, а контактами 10.2 и 10.4 отключает реле 16 и замыкает рабочую цепь контактами 10.1, 10.3, 10.5. Сработав, реле 9 контактом 9.3 размыкает цепь возбуждени реле 10, а контактами 9.1 и 9.2 подключает обмотки 2, 3 и 4 электродвигател к фазам 23 24 и 25.Relay 10 by contact 10.6 closes the excitation circuit of a polarized starting relay 9, and contacts 10.2 and 10.4 disconnects relay 16 and closes the operating circuit by contacts 10.1, 10.3, 10.5. By operating, relay 9 with contact 9.3 opens the excitation circuit of relay 10, and contacts 9.1 and 9.2 connects windings 2, 3 and 4 of the electric motor to phases 23 24 and 25.
При переводе стрелки реле 10 получает блокировку от рабочего тока через фазоконтрольный блок 15. После перевода стрелки контактами 7 и 8 автопереключател привода 1 размыкаетс цепь обмоток 2, 3, 4 электродвигател , а после размыкани цепи обмоток 2, 3, 4 обесточиваетс реле 10 и контактами 10.2 и 10.4 подключает через контакты 9.1 и 9.2 пол ризованного пускового реле 9 реле 16 к контакта.м 7 и 8 автопереключател .When switching the arrow, relay 10 acquires a blockage from the operating current through the phase control unit 15. After transferring the arrow by contacts 7 and 8, the autoswitch drive 1 opens the circuit of windings 2, 3, 4 of the electric motor, and after opening the circuit of windings 2, 3, 4 de-energizes the relay 10 and contacts 10.2 and 10.4 connects via contacts 9.1 and 9.2 of the polarized starting relay 9 relays 16 to contacts.m 7 and 8 of the auto-switch.
