Description

Изобретение относитс  к устройствам дл  автоматического управлени  включением сварочной цепи при дуговой сварке посто нным током. Известные устройства такого рода, осуществл ющие включение сварочной цепи при замыкании электрода с изделием и отключение цепи при отрыве дуги, сложны по устройству и содержат значительное число элементов в схеме управлени .The invention relates to devices for automatically controlling the switching of the welding circuit in direct current arc welding. The known devices of this kind, which turn on the welding circuit when the electrode closes with the product and disconnect the circuit when the arc is disconnected, are complex in structure and contain a significant number of elements in the control circuit.

Дл  упрощени  устройства предлагаетс , согласно изобретению, катушку промежуточного реле, управл ющего контактором сварочной цепи , включить на питание от независимого источника посто нного тока через вентиль и дуговой промежуток электрод - изделие.To simplify the device, it is proposed, according to the invention, to coil an intermediate relay controlling the contactor of the welding circuit to be powered by an independent direct current source through a valve and an arc gap, the electrode - product.

На чертеже изображена электрическа  схема устройства.The drawing shows the electrical circuit of the device.

Сварочна  цепь, содержаща  электрод 1 и изделие 2, подключаетс  к источнику посто нного сварочного тока контактом 3 однополюсного контактора. Катушка 4 промежуточного реле, управл ющего контактором сварочной цепи, подключаетс  к зажимам 5 независимого источника посто нного токаThe welding circuit containing the electrode 1 and the product 2 is connected to a source of direct welding current by pin 3 of a single-pole contactor. Coil 4 of the intermediate relay controlling the welding circuit contactor is connected to terminals 5 of an independent DC source.

через вентиль 6 н дугово промеж ток электрод-изделие. Конденсатор 7 включен параллельно катушке промежуточного реле дл  замедлени  времени его срабатывани .through the valve 6 n arc between the current electrode product. Capacitor 7 is connected parallel to the coil of the intermediate relay to slow down its response time.

Устройство работает следующим образомПри замыкании электрода па изделие замыкаетс  цепь питани  катущки 4 промежуточного реле, включаетс  контактор и замыкаетс  контакт 3. Сварочна  цепь подключена к источнику сварочного тока и происходит сварка. Вентиль 6 преп тствует прохождению тока из сварочной цепи в цепь управлени .The device operates as follows. When the electrode is closed, the product closes the supply circuit of the coil 4 of the intermediate relay, the contactor is turned on and the contact 3 is closed. The welding circuit is connected to the source of welding current and welding takes place. Valve 6 prevents the passage of current from the welding circuit to the control circuit.

При отрыве сварочной дуги .цепь питани  катушки 4 промежуточного реле разрываетс , реле выключаетс  и выключает контактор; при этом сварочна  цепь отключаетс  от источника сварочного токаКонденсатор 7 замедл ет врем  срабатывани  промежуточного реле и предотвращает отключение сварочной цепи при кратковременных перерывах в горении сварочной дуги .When the welding arc is removed, the power supply circuit of the coil 4 of the intermediate relay is broken, the relay turns off and turns off the contactor; at the same time, the welding circuit is disconnected from the source of welding current. Capacitor 7 slows down the response time of the intermediate relay and prevents the welding circuit from shutting down during short breaks in the welding arc.
