Analysis ea Thyristor Switching Circuit in Medium Frequency Inverter Spot Welding Machine

The thyristor switching circuit e bapala karolo ea bohlokoa ts'ebetsong ea mochini oa welding oa maqhubu a mahareng. E thusa ho laola le ho laola matla a motlakase, ho nolofalletsa mekhoa e nepahetseng le e sebetsang ea welding. Sehloohong sena, re tla fana ka tlhahlobo e tebileng ea potoloho ea thyristor ka mochini oa welding oa maqhubu a mahareng a maqhubu a motlakase.

1. Sebopeho sa Motheo sa Thyristor Switching Circuit: The thyristor switching circuit e na le likarolo tse 'maloa tsa bohlokoa, tse kenyelletsang li-thyristors (tse tsejoang hape e le li-rectifiers tse laoloang ke silicon), li-circuits tsa taolo ea liheke, li-circuits tsa trigger, le lisebelisoa tse sireletsang. Likarolo tsena li sebetsa hammoho ho laola phallo ea motlakase le ho netefatsa ts'ebetso e bolokehileng le e tšepahalang ea mochini oa welding.
2. Mosebetsi oa Thyristors: Thyristors ke lisebelisoa tsa semiconductor tse sebetsang e le li-switches tse laoloang ke motlakase. Li lumella hona joale hore li phalle ka tsela e le 'ngoe ha li tsosoa,' me hang ha li khanna, li lula li tsamaisa ho fihlela marotholi a hona joale a theoha ka tlas'a moeli o itseng. Sebakeng sa phetoho, li-thyristors li sebelisoa ho laola phepelo ea matla ho sesebelisoa sa welding.
3. Lipotoloho tsa Taolo ea Liheke: Li-circuits tsa taolo ea liheke li na le boikarabello ba ho susumetsa li-thyristors le ho laola ketso ea bona ea ho fetola. Ba hlahisa lipontšo tse nepahetseng le tse behiloeng ka nako tse qalang ho tsamaisa li-thyristors. Li-circuits tsa taolo ea liheke li etselitsoe ho etsa bonnete ba hore ho lumellana ho nepahetseng le ho hokahanya ha mokhoa oa ho fetola thyristor.
4. Li-circuits tsa Trigger: Li-circuits tsa trigger li fana ka matšoao a hlokahalang ho li-circuits tsa taolo ea liheke. Lipontšo tsena li hlahisoa ho ipapisitsoe le litekanyo tse lakatsehang tsa welding, joalo ka ha joale, nako ea welding le matla a electrode. Li-circuits tsa trigger li netefatsa hore li-thyristors li tsosoa ka nako e nepahetseng ho fihlela litšobotsi tse lakatsehang tsa welding.
5. Lisebelisoa tsa Tšireletso: Ho netefatsa tšireletso ea mochine oa welding le ho thibela tšenyo ea likaroloana, lisebelisoa tse sireletsang li kenngoa ka har'a potoloho ea thyristor switching. Lisebelisoa tsena li kenyelletsa tšireletso e feteletseng, tšireletso ea overvoltage, le ho hlahloba mocheso. Ba lemoha le ho arabela maemong a sa tloaelehang, joalo ka hona joale kapa motlakase o feteletseng, 'me ba kenya tšebetsong mehato ea ts'ireletso ho thibela ho hloleha kapa ho senyeha ha sistimi.
6. Taolo le Taolo ea Matla: The thyristor switching circuit e etsa hore ho be le taolo e nepahetseng le taolo ea matla mochining oa welding oa frequency inverter spot. Ka ho lokisa matšoao a susumetsang le li-circuits tsa taolo ea liheke, matla a fanoang ho transformer ea welding a ka fetoloa ho fihlela litšobotsi tse lakatsehang tsa welding, joalo ka matla a weld, ho kenella le ho kenya mocheso.

The thyristor switjha potoloho ka seaplane maqhubu inverter spot welding mochine ke karolo ea bohlokoa e nolofalletsang taolo e nepahetseng le taolo ea matla a motlakase. Ka tšebelisano ea li-thyristors, li-circuits tsa taolo ea liheke, li-circuits tsa trigger, le lisebelisoa tsa ts'ireletso, mochini oa welding o ka fana ka lits'ebetso tse nepahetseng le tse sebetsang hantle tsa welding. Tlhahlobo ea potoloho ea thyristor switching e fana ka leseli mabapi le sebopeho sa eona sa mantlha le ts'ebetso, e totobatsa bohlokoa ba eona ho fihlela li-welds tsa boleng bo holimo le ho netefatsa ts'ebetso e bolokehileng ea mochini oa welding.
