Lesi sihloko sinikeza ukuhlaziywa okujulile kwesistimu ye-inverter kumishini yokushisela i-medium frequency inverter spot welding. Uhlelo lwe-inverter ludlala indima ebalulekile ekuguquleni amandla okufaka abe yifrikhwensi oyifunayo kanye ne-voltage ukuze kube nokusebenza kahle kokushisela indawo. Ukuqonda ukusebenza kanye nezingxenye zesistimu ye-inverter kubalulekile ekuthuthukiseni ukusebenza nokuthembeka kwale mishini yokushisela. Lesi sihloko sihlola izici ezibalulekile zesistimu ye-inverter futhi sikhanyisela izimiso zayo zokusebenza.
- Uhlolojikelele lwe-Inverter System: Uhlelo lwe-inverter emishinini yokushisela i-medium frequency inverter spot luqukethe izingxenye ezimbalwa, okuhlanganisa umthombo wamandla, isilungisi, isekethe ye-inverter, kanye neyunithi yokulawula. Umthombo wamandla unikeza amandla okokufaka, abese eguqulelwa ku-direct current (DC) ngesilungisi. Amandla e-DC aphinde acutshungulwe futhi aguqulelwe ku-high-frequency alternating current (AC) yisekethe ye-inverter. Iyunithi yokulawula ilawula ukusebenza kanye nemingcele yesistimu ye-inverter ukuqinisekisa ukulawula okunembile nokusebenza kahle.
- I-Pulse Width Modulation (PWM) Technique: Uhlelo lwe-inverter lusebenzisa inqubo ye-Pulse Width Modulation (PWM) ukuze ilawule amandla kagesi aphumayo kanye nawamanje. I-PWM ihilela ukushintsha ngokushesha amandla ngemvamisa ephezulu, ukulungisa isikhathi esisebenza ngaso nesikhathi sokuvala amaswishi ukuze kuzuzwe isilinganiso esidingekayo sokukhipha amandla kagesi. Le nqubo ivumela ukulawula okunembile kwamandla okushisela kanye namandla, okuholela kukhwalithi ye-weld engaguquki kanye nokusebenza kahle okuthuthukisiwe.
- Amadivayisi we-Semiconductor Amandla: Amadivayisi we-semiconductor yamandla afana ne-Insulated Gate Bipolar Transistors (IGBTs) avame ukusetshenziswa kumjikelezo we-inverter. Ama-IGBT anikezela ngesivinini esikhulu sokushintsha, ukulahlekelwa amandla aphansi, nezici ezinhle kakhulu zokushisa, okuwenza afanelekele izinhlelo zokusebenza zefrikhwensi emaphakathi. Lawa madivayisi aphatha ukushintsha nokulawula ukugeleza kwamanje, okuqinisekisa ukuguqulwa kwamandla okusebenzayo kanye nokunciphisa ukukhiqizwa kokushisa.
- Ukuhlunga Nokulawula Okuphumayo: Ukuqinisekisa i-voltage ephumayo ezinzile futhi ehlanzekile, uhlelo lwe-inverter luhlanganisa izingxenye zokuhlunga ezifana nama-capacitor nama-inductors. Lezi zakhi zishelela i-waveform okukhiphayo, kunciphisa ukuhambisana nokuphazamiseka. Ukwengeza, iyunithi yokulawula ihlale iqapha futhi ilungisa amapharamitha okukhiphayo, njenge-voltage, yamanje, kanye nemvamisa, ukuze ihambisane nezidingo zokushisela ezifunwayo.
- Izici Zokuvikela Nokuphepha: Uhlelo lwe-inverter luhlanganisa izindlela ezihlukahlukene zokuvikela ukuvikela okokusebenza kanye nabaqhubi. Ukuvikela okweqile, ukuvikeleka kwesekethe emfishane, nokuvikela ukugcwala okushisayo kuvame ukusetshenziswa ukuze kuvinjelwe ukulimala kwezingxenye zesistimu. Ukwengeza, izici zokuphepha ezifana nokutholwa kwamaphutha aphansi kanye nokuqapha amandla kagesi kuqinisekisa ukusebenza okuphephile futhi kunciphisa ubungozi bezingozi.
Isiphetho: Uhlelo lwe-inverter emishinini yokushisela i-medium frequency inverter spot luyingxenye ebalulekile eyenza ukulawulwa okunembile kwemingcele yokushisela futhi iqinisekise ukuguqulwa kwamandla okuphumelelayo. Ngokuqonda izimiso zokusebenza nezingxenye zesistimu ye-inverter, abasebenzisi bangakwazi ukwandisa ukusebenza, ukwethembeka, nokuphepha kwale mishini yokushisela. Intuthuko eqhubekayo kubuchwepheshe bamandla kagesi inegalelo ekuthuthukisweni kwamasistimu e-inverter asebenza kahle kakhulu futhi ayinkimbinkimbi, okuthuthukisa ukuthuthukiswa kwezinhlelo zokusebenza zokushisela kuzo zonke izimboni ezihlukahlukene.
