Abstract
Использование: коммутационна аппаратура переменного тока. Сущность изобретени : включение устройства производитс при положительной фазе напр жени источника питани (на выводе 6- плюс, на выводе 7- минус). При этом сначала замыкаетс контакт 2-1, затем, при смене пол рности , контакт 1-1. Отключение производитс при отрицательной фазе напр жени . При этом сначала размыкаетс контакт 1-1, затем при изменении пол рности напр жени - контакт 2-1. Диод 3 способствует рассе нию электромагнитной энергии, накопленной в индуктивности нагрузки 5. 2 ил.Use: switching equipment of alternating current. SUMMARY OF THE INVENTION: The device is turned on with a positive phase of the power supply voltage (at pin 6, plus, at pin 7, minus). At the same time, contact 2-1 is first closed, then, when the polarity is changed, contact 1-1. The disconnection is made at a negative voltage phase. In this case, contact 1-1 is first opened, then when the voltage polarity is changed, contact 2-1. Diode 3 contributes to the dissipation of electromagnetic energy stored in the load inductance 5. 2 Il.
