Lesi sihloko sigxile ezindleleni nezindlela ezisetshenziswayo ukuze kuthuthukiswe amandla emishini yokushisela i-medium frequency inverter spot. Isici samandla ipharamitha ebalulekile ekala ukusebenza kahle kokusetshenziswa kwamandla kagesi emisebenzini yokushisela. Ngokuqonda izici ezithonya isici samandla nokusebenzisa ukuthuthukiswa okufanele, abakhiqizi nabaqhubi bangathuthukisa ukusebenza kahle kwamandla, banciphise ukusetshenziswa kwamandla, futhi bathuthukise ukusebenza kwemishini yokushisela.
- Ukuqonda Isici Samandla: Isici samandla isilinganiso sesilinganiso phakathi kwamandla wangempela (asetshenziselwa ukwenza umsebenzi owusizo) namandla abonakalayo (inani lamandla anikeziwe) ohlelweni lukagesi. Isuka ku-0 iye ku-1, enesici samandla esiphezulu esibonisa ukusetshenziswa kahle kwamandla. Emishinini yokushisela, ukuzuza isici samandla aphezulu kuyafiseleka njengoba kunciphisa ukulahleka kwamandla asebenzayo, kunciphisa ukumosheka kwamandla, futhi kuthuthukisa ukusebenza kohlelo lonke.
- Izinto Ezithonya I-Power Factor: Izinto eziningi zithinta isici samandla emishini yokushisela ye-medium frequency inverter spot:
a. Imithwalo ye-Capacitive noma Inductive: Ukuba khona kwemithwalo ye-capacitive noma inductive kumjikelezo we-welding kungaholela ekubambeni noma ekuholeni kwamandla, ngokulandelanayo. Ekushiseleni indawo, i-welding transformer nezinye izakhi zingase zibe nomthelela emandleni asebenzayo.
b. I-Harmonics: I-Harmonics ekhiqizwe imithwalo engeyona imigqa, njengamandla asekelwe ku-inverter, ingahlanekezela isici samandla. Lawa ma-harmonics adala ukusetshenziswa kwamandla okusebenzayo okwengeziwe futhi anciphise isici samandla.
c. Amasu okulawula: Isu lokulawula elisetshenziswa ku-inverter yomshini wokushisela lingathonya isici samandla. Amasu okulawula athuthukile athuthukisa isici samandla angasetshenziswa ukuthuthukisa ukusebenza kahle.
- Izindlela Zokuthuthukisa Isici Samandla: Ukuthuthukisa isici samandla emshinini wokushisela we-medium frequency inverter spot, lezi zinyathelo ezilandelayo zingenziwa:
a. Ama-Capacitor Okulungisa I-Power Factor: Ukufaka ama-capacitor okulungisa isici samandla kunganxephezela amandla asebenzayo ohlelweni, okuholela kusici samandla esiphezulu. Lawa ma-capacitor asiza ukulinganisa amandla asebenzayo futhi athuthukise ukusebenza kahle kohlelo lonke.
b. Ukuhlunga Okusebenzayo: Izihlungi zamandla asebenzayo zingasetshenziswa ukunciphisa ukuhlanekezela kwe-harmonic okubangelwa imithwalo engaqondile. Lezi zihlungi zijova ama-currents anxephezelayo ukuze kukhanselwe ama-harmonics, okuholela ekuhlanzekeni kwegagasi lamandla kanye nezici zamandla ezithuthukisiwe.
c. I-Inverter Control Optimization: Ukusebenzisa ama-algorithms okulawula okuthuthukile ku-inverter kungathuthukisa isici samandla ngokunciphisa ukusetshenziswa kwamandla okusebenzayo. Amasu afana nokulawula i-pulse-width modulation (PWM) namasu okulawula okuguquguqukayo angasetshenziswa ukuze kuzuzwe ukusebenza okungcono kwesici samandla.
Ukuthuthukisa isici samandla emishinini yokushisela i-medium frequency inverter spot ibalulekile ekuthuthukiseni ukusebenza kahle kwamandla nokusebenza kahle. Ngokubhekana nezici ezifana nemithwalo ye-capacitive noma inductive, i-harmonics, namasu okulawula, abakhiqizi nabasebenza bangafinyelela isici samandla esiphezulu. Ukusetshenziswa kwama-capacitor okulungisa isici samandla, ukuhlunga okusebenzayo, kanye namasu okulawula isishintshi esithuthukisiwe kuyizindlela ezisebenzayo zokuthuthukisa isici samandla kanye nokunciphisa ukulahleka kwamandla asebenzayo. Lokhu kuthuthukiswa kuphumela ekuncishisweni kokusetshenziswa kwamandla, ukusebenza kahle kwamandla, kanye nenqubo yokushisela esimeme kakhudlwana. Ngokwamukela izinyathelo zokuthuthukisa isici samandla, imboni yokushisela ingaba nomthelela ohlelweni lokukhiqiza oluluhlaza futhi olusebenza kahle kakhulu.
