Izingxenye Ezithambekele Ekushiseni Emishinini Yokushisela Yendawo Ephakathi-Frequency Inverter?

Emishinini yokushisela indawo ye-inverter ye-medium-frequency, izakhi ezithile ziyakwazi ukushisisa ngesikhathi sokusebenza. Ukuqonda lezi zingxenye kanye nokukhiqiza kwazo ukushisa okungaba khona kubalulekile ekugcineni ukusebenza kahle nokuvimbela izinkinga zokushisisa ngokweqile. Lesi sihloko sihlola izingxenye ezijwayele ukushisisa emishinini yokushisela indawo ye-inverter ye-medium-frequency.

1. I-Inverter Module: I-inverter module ingenye yezingxenye ezibalulekile emshinini wokushisela onesibopho sokuguqula amandla okufaka abe amandla aphezulu e-AC. Ngenxa ye-high switching frequencies ehilelekile, imojula ye-inverter ingakwazi ukukhiqiza ukushisa ngesikhathi sokusebenza. Izinyathelo zokupholisa ezanele, njengamasinki okushisa noma izifeni, zibalulekile ukuze kuqedwe lokhu kushisa nokuvimbela ukushisa ngokweqile.
2. I-Transformer: I-transformer emshinini we-welding we-medium-frequency spot welding ingenye ingxenye engase ihlangabezane nokufudumeza. Njengoba ishintsha i-voltage, ukulahlekelwa kwamandla kwenzeka, okuholela ekukhiqizeni ukushisa. Idizayini efanele ye-transformer, okuhlanganisa ukukhethwa kwezinto eziyisisekelo ezifanele kanye nokuhlelwa kwamajika, kubalulekile ukuze kuncishiswe ukulahlekelwa nokulawula ukushisa ngempumelelo.
3. Ama-Rectifier Diode: Ama-diode okulungisa asetshenziselwa ukuguqula amandla e-AC emvamisa ephezulu abe amandla e-DC ngenqubo yokushisela. Ngesikhathi sokulungiswa, lawa ma-diode angakwazi ukukhiqiza ukushisa, ikakhulukazi uma engaphansi kwemisinga ephezulu. Ukuqinisekisa ukuchithwa okufanele kokushisa ngamasinki okushisa noma amafeni okupholisa kuyadingeka ukuze kuvinjelwe ukushisa kwe-diode nokugcina ukusebenza kwazo nokuphila isikhathi eside.
4. Ama-Capacitor: Ama-Capacitor asetshenziswa emishinini yokushisela indawo ye-inverter ye-medium-frequency spot ngezinjongo ezihlukahlukene, njengokuhlunga nokugcina amandla. Imisinga ephezulu edlula kuma-capacitor ingaholela ekulahlekeni kokushisa. Ukulinganisa okufanelekile, ukukhethwa kwama-capacitor ane-serial equivalent series resistance (ESR), kanye nezindlela zokupholisa ezisebenzayo kubalulekile ukuze kuvinjelwe ukushisa okweqile kuma-capacitor.
5. Ama-Semiconductors Amandla: Ama-semiconductors kagesi, afana ne-insulated gate bipolar transistors (IGBTs) noma i-metal-oxide-semiconductor field-effect transistors (ama-MOSFET), ayizingxenye ezibalulekile zokulawula nokulawula i-welding current. Lawa ma-semiconductors angakwazi ukukhiqiza ukushisa ngesikhathi sokusebenza okuphezulu kwamanje. Ukusebenzisa amasinki okushisa afanelekile kanye nokuqinisekisa ukuchithwa kokushisa okuphumelelayo kubalulekile ukuze kuvinjelwe ukushisa ngokweqile nokugcina ukusebenza nokuthembeka kwawo.

Izingxenye eziningana emishinini yokushisela indawo ye-inverter ye-medium-frequency ijwayele ukushisa ngesikhathi sokusebenza. Imojula ye-inverter, i-transformer, i-rectifier diode, ama-capacitor, nama-semiconductors amandla aphakathi kwezingxenye ezidinga ukunakwa ukuvimbela ukushisa ngokweqile. Izindlela zokupholisa ezifanele, ezihlanganisa amasinki okushisa, izifeni, nokugeleza komoya okwanele, kufanele zisetshenziswe ukuze kuqedwe ukushisa ngokuphumelelayo futhi kugcinwe ukusebenza nokuphila isikhathi eside kwezingxenye. Ukuqapha nokugcinwa njalo kwalezi zingxenye kunomthelela ekusebenzeni kahle nokuthembekile kwemishini yokushisela indawo ye-inverter ye-medium-frequency.
