Eli nqaku libonelela ngohlalutyo olunzulu lwenkqubo ye-inverter kwi-medium frequency inverter spot welding machine. Inkqubo ye-inverter idlala indima ebalulekileyo ekuguquleni amandla okufaka kwi-frequency efunwayo kunye ne-voltage yokusebenza ngokufanelekileyo kwe-welding. Ukuqonda ukusebenza kunye namacandelo e-inverter system kubalulekile ekuphuculeni ukusebenza kunye nokuthembeka kwaba matshini be-welding. Eli nqaku liphonononga imiba ephambili yenkqubo ye-inverter kwaye inika ukukhanya kwimigaqo yayo yokusebenza.
- Isishwankathelo seNkqubo ye-Inverter: Inkqubo ye-inverter kwi-medium frequency inverter spot welding machine iqulathe amacandelo amaninzi, kubandakanywa umthombo wamandla, isilungisi, i-inverter circuit, kunye neyunithi yokulawula. Umthombo wamandla unika amandla egalelo, athi ke aguqulelwe kumbane othe ngqo (DC) ngokulungisa. Umbane we-DC uphinde uqhutywe kwaye uguqulelwe kwi-high-frequency alternating current (AC) yi-inverter circuit. Iyunithi yokulawula ilawula ukusebenza kunye neeparitha zenkqubo ye-inverter ukuqinisekisa ulawulo oluchanekileyo kunye nokusebenza kakuhle.
- I-Pulse Width Modulation (PWM) Technique: Isixokelelwano soguqulo sisebenzisa i-Pulse Width Modulation (PWM) ubuchule bokulawula umbane ophumayo kunye nowangoku. I-PWM ibandakanya ukutshintshela ngokukhawuleza amandla kwi-frequency ephezulu, ukulungelelanisa ixesha kunye nexesha lokungabikho kwezitshixo ukufezekisa umndilili ofunekayo wokukhupha amandla. Obu buchule buvumela ulawulo oluchanekileyo lwe-welding yangoku kunye namandla, okukhokelela kumgangatho we-weld ongaguqukiyo kunye nokusebenza kakuhle.
- Izixhobo ze-Semiconductor zamandla: Izixhobo ze-semiconductor zamandla ezifana ne-Insulated Gate Bipolar Transistors (IGBTs) zisetyenziswa ngokuqhelekileyo kwisekethe ye-inverter. Ii-IGBTs zibonelela ngesantya esiphezulu sokutshintsha, ukulahleka kwamandla aphantsi, kunye neempawu ezibalaseleyo zobushushu, zibenza bafanelekele usetyenziso oluphakathi. Ezi zixhobo zibamba ukutshintshwa kunye nokulawula ukuhamba kwangoku, ukuqinisekisa ukuguqulwa kwamandla okusebenzayo kunye nokunciphisa ukuveliswa kobushushu.
- Ukucoca kunye noLawulo lokuPhuma: Ukuqinisekisa i-voltage ephumayo ezinzileyo kwaye ecocekileyo, inkqubo ye-inverter ibandakanya izinto zokucoca ezifana ne-capacitors kunye ne-inductors. Ezi zinto zigudisa i-wave waveform, ukunciphisa i-harmonics kunye nokuphazamiseka. Ukongeza, iyunithi yokulawula ngokuqhubekayo ibeka iliso kwaye ihlengahlengise iiparamitha zokuphuma, ezifana ne-voltage, yangoku, kunye ne-frequency, ukuhambelana neemfuno ezifunwayo ze-welding.
- Iimpawu zoKhuselo kunye noKhuseleko: Inkqubo ye-inverter ibandakanya iindlela ezahlukeneyo zokukhusela ukukhusela izixhobo kunye nabaqhubi. Ukukhuselwa kwe-Overcurrent, ukukhusela i-short-circuit, kunye nokukhuselwa kwe-thermal overload ngokuqhelekileyo kusetyenziswe ukukhusela umonakalo kumacandelo enkqubo. Ukongezelela, iimpawu zokhuseleko ezifana nokufunyanwa kwempazamo yomhlaba kunye nokujongwa kwamandla ombane ziqinisekisa ukusebenza ngokukhuselekileyo kunye nokunciphisa umngcipheko weengozi.
Isiphelo: Inkqubo ye-inverter kumatshini we-welding we-inverter spot ephakathi licandelo elibalulekileyo elenza ulawulo oluchanekileyo lweeparamitha ze-welding kunye nokuqinisekisa ukuguqulwa kwamandla okusebenzayo. Ngokuqonda imigaqo yokusebenza kunye namacandelo e-inverter system, abasebenzisi banokwandisa ukusebenza, ukuthembeka, kunye nokhuseleko lwaba matshini be-welding. Ukuqhubela phambili okuqhubekayo kwitekhnoloji ye-elektroniki yamandla inegalelo kuphuhliso lweenkqubo zoguqulo olusebenzayo neziphucukileyo, ukuqhubela phambili uphuculo kwizicelo ze-welding kuwo wonke amashishini ahlukeneyo.
