Abstract

FIELD: electric engineering. SUBSTANCE: device has unit for switching main contact 2 off without arc due to fact that it is by- passed by main thyristor 3, which is rendered conducting in initial moment when contact is broken by means of starting circuit which has capacitor 9 and diode 10. Said thyristor 3 is rendered non- conducting by means of forced switching unit which has switching thyristor 4 and capacitor 5, which is charged by means of charging circuit which has thyristor 6 and resistor 7. Thyristor 6 is controlled by serial circuit of resistor 17, capacitor 18 and contacts 19 of end switch, which is connected mechanically to moving part of contactor. EFFECT: increased functional capabilities. 1 dwg

Контактор постоянного тока снабжен устройством для бездугового размыкания главного контакта 2 благодаря шунтированию его основным тиристором 3, отпираемым в начальный момент размыкания контакта с помощью пусковой цепочки, состоящей из конденсатора 9 и диода 10. Запирание тиристора 3 обеспечивается блоком принудительной коммутации, включающим коммутирующие тиристор 4 и конденсатор 5. Конденсатор 5 заряжается при помощи зарядной цепи, состоящей из тиристора 6 и резистора 7. Тиристор 6 управляется цепочкой последовательно соединенных резистора 17, конденсатора 18 и контактов 19 концевого переключателя, механически связанного с подвижной частью контактора.The DC contactor is equipped with a device for arc-free opening of the main contact 2 due to its shunting by the main thyristor 3, which is unlocked at the initial moment of opening the contact using a starting circuit consisting of a capacitor 9 and a diode 10. The thyristor 3 is locked by a forced switching unit, including switching thyristor 4 and capacitor 5. The capacitor 5 is charged using a charging circuit consisting of a thyristor 6 and a resistor 7. The thyristor 6 is controlled by a chain of resistors connected in series pa 17, capacitor 18 and contacts the limit switch 19 mechanically connected to the movable contactor.
