Tlhahlobo ea Sisteme ea Inverter ho Mechini ea Welding ea Nako e Bohareng ea Inverter Spot

Sengoliloeng sena se fana ka tlhahlobo e tebileng ea sistimi ea inverter ho mechini ea welding ea maqhubu a mahareng. Sistimi ea inverter e bapala karolo ea bohlokoa ho fetoleng matla a kenyelletso hore e be maqhubu a batloang le voltage bakeng sa ts'ebetso e nepahetseng ea li-welding. Ho utloisisa ts'ebetso le likarolo tsa sistimi ea inverter ho bohlokoa bakeng sa ho ntlafatsa ts'ebetso le ts'epahalo ea mechini ena ea welding. Sengoliloeng sena se hlahloba lintlha tsa bohlokoa tsa sistimi ea inverter mme se fana ka leseli mabapi le melao-motheo ea ts'ebetso ea eona.

1. Kakaretso ea Sisteme ea Inverter: Sistimi ea inverter ka har'a mechini ea welding ea maqhubu a mahareng e na le likarolo tse 'maloa, ho kenyelletsa mohloli oa matla, rectifier, potoloho ea inverter le yuniti ea taolo. Mohloli oa matla o fana ka matla a ho kenya, ao joale a fetoloang ho direct current (DC) ka ho lokisa. Motlakase oa DC o tsoela pele ho sebetsoa le ho fetoloa ho ba maqhubu a phahameng a feto-fetohang (AC) ke potoloho ea inverter. Sehlopha sa taolo se laola ts'ebetso le liparamente tsa sistimi ea inverter ho netefatsa taolo e nepahetseng le ts'ebetso e nepahetseng.
2. Technique ea Pulse Width Modulation (PWM): Sisteme ea inverter e sebelisa mokhoa oa Pulse Width Modulation (PWM) ho laola motlakase o tsoang le oa hajoale. PWM e kenyelletsa ho fetola matla ka potlako ka lebelo le phahameng, ho lokisa nako le nako ea ho tima ha li-switches ho fihlela motlakase o batloang o batloang. Mokhoa ona o lumella hore ho be le taolo e nepahetseng ea hona joale ea welding le matla, e leng se fellang ka boleng bo tsitsitseng ba weld le ts'ebetso e ntlafetseng.
3. Lisebelisoa tsa Semiconductor ea Matla: Lisebelisoa tsa semiconductor tsa matla tse kang Insulated Gate Bipolar Transistors (IGBTs) li atisa ho sebelisoa ka potoloho ea inverter. Li-IGBT li fana ka lebelo le phahameng la ho fetoha, tahlehelo ea matla a tlase, le litšobotsi tse ntle tsa mocheso, tse etsang hore li tšoanelehe bakeng sa lits'ebetso tsa maqhubu a mahareng. Lisebelisoa tsena li sebetsana le ho fetola le ho laola phallo ea hona joale, ho netefatsa phetoho e nepahetseng ea matla le ho fokotsa tlhahiso ea mocheso.
4. Tlhophiso le Taolo ea Liphetho: Ho etsa bonnete ba hore ho na le motlakase o tsitsitseng le o hloekileng, sistimi ea inverter e kenyelletsa likarolo tsa ho sefa joalo ka li-capacitor le li-inductors. Lintho tsena li theola sebopeho sa wave wave, ho fokotsa li-harmonics le tšitiso. Ntle le moo, yuniti ea taolo e lula e beha leihlo le ho lokisa liparamente tsa tlhahiso, joalo ka voltage, hajoale, le frequency, ho tsamaisana le litlhoko tse lakatsehang tsa welding.
5. Likarolo tsa Ts'ireletso le Ts'ireletso: Sistimi ea inverter e kenyelletsa mekhoa e fapaneng ea ts'ireletso ho sireletsa lisebelisoa le basebelisi. Tšireletso ea overcurrent, tšireletso ea potoloho e khutšoanyane, le ts'ireletso ea mocheso oa mocheso hangata li sebelisoa ho thibela tšenyo ea likarolo tsa tsamaiso. Ho feta moo, likarolo tsa ts'ireletso tse joalo ka ho lemoha liphoso tsa fatše le tlhahlobo ea motlakase li netefatsa ts'ebetso e bolokehileng le ho fokotsa kotsi ea likotsi.

Qetello: Sistimi ea inverter mochining oa welding oa maqhubu a mahareng ke karolo ea bohlokoa e lumellang taolo e nepahetseng ea liparamente tsa welding le ho netefatsa phetoho e nepahetseng ea matla. Ka ho utloisisa melao-motheo ea ts'ebetso le likarolo tsa sistimi ea inverter, basebelisi ba ka ntlafatsa ts'ebetso, ts'epahalo le polokeho ea mechini ena ea welding. Tsoelo-pele e tsoelang pele ea theknoloji ea elektroniki ea motlakase e kenya letsoho ho nts'etsopele ea li-inverter tse sebetsang hantle le tse tsoetseng pele, tse tsamaisang lintlafatso lits'ebetsong tsa welding libakeng tse fapaneng.
