Iyini i-solid state soft starter?
I-solid state soft starter iyidivayisi kagesi esetshenziselwa ukulawula i-voltage esetshenziswa ku-AC motor ngesikhathi sokuqalisa. Ngokusebenzisa i-thyristors (ama-SCR) noma amanye amadivayisi e-semiconductor, iziqalisi ezithambile zikhawulela i-inrush current yokuqala futhi zinciphise ukucindezeleka komshini ku-motor kanye nemishini yokuxhuma. Izici eziyinhloko zeziqalisi ezithambile ze-solid-state zifaka: i-soft starter ithatha isikhala esincane kunezindlela zokuqala zendabuko njenge-autotransformers. Izinzuzo zeziqalisi ezithambile ze-solid state zifaka: i-voltage yemoto iyanda kancane kancane esikhathini esichazwe kusengaphambili. Amaphrofayili okuqala angenziwa ngezifiso: Abasebenzisi bangalungisa amapharamitha njengesikhathi sokuma kanye ne-torque yokuqala. Umsebenzi wokuvikela: Iziqalisi ezithambile zivame ukufaka Ukuvikelwa Kokulayisha Okungaphezu Komthwalo, ukuqapha ukungalingani kwesigaba kanye nokuvikelwa kokungasebenzi kahle kwamandla kagesi. Umklamo ohlangene: Iziqalisi ezithambile zithatha isikhala esincane kunezindlela zokuqalisa zendabuko ezifana nama-autotransformer. Izinzuzo zeziqalisi ezithambile zesimo esiqinile
1. Ukunciphisa ukucindezeleka komshini (ngokuqondile ku-inthanethi) kungaholela ekukhuphukeni kwe-torque okungazelelwe, okungaholela ekugugeni kwenjini kanye nemishini eqhutshwayo. Iziqalisi ezithambile zinciphisa lokhu kukhuphuka futhi zandise impilo yezingxenye zomshini.
2. Ugesi ophezulu ongenayo ekuqaleni ngqo ungacindezela inethiwekhi kagesi, okungabangela ukwehla kwamandla kagesi futhi kuthinte eminye imishini. Isiqalo esithambile sinciphisa kakhulu la mandla, siqinisekise ukusebenza kwamandla okuzinzile.
3. Nakuba iziqalisi ezithambile zenzelwe kakhulu ukuqalisa nokuvala, ikhono lazo lokunciphisa ukulahlekelwa phakathi nalezi zigaba lisiza ekusebenzeni kahle kwesistimu iyonke.
4. Ukuthembeka kohlelo okuthuthukisiwe Ngokuvikelwa okuhlanganisiwe, iziqalisi ezithambile zithuthukisa ukuthembeka kohlelo lwemoto ngokuvimbela umonakalo obangelwa ukwehluleka kukagesi noma izimo zokulayisha ngokweqile. Iziqalisi ezithambile zesimo esiqinile zizuzisa kakhulu ezimbonini lapho izinjini ezinamandla aphezulu naphakathi (ngokuvamile kusuka ku-2.3 kV kuya ku-13.8 kV) ziqhuba imithwalo emikhulu, njenge: uwoyela negesi: ama-compressor, amaphampu, kanye namafeni. Ukumba: Izigayo zikagesi zama-conveyor, ama-crusher kanye nokugaya.
Amanzi namanzi angcolile: amaphampu amakhulu nama-blower.
Ukukhiqizwa kukagesi: Kusetshenziswa ukulawula imishini yokusiza efana namaphampu okuphakelayo kanye nabalandeli bombhoshongo wokupholisa.
Izinselele kanye nokucatshangelwa
Isinyathelo 1 Qeda ukushisa
Iziqalisi ezithambile zikhiqiza ukushisa ngesikhathi sokusebenza, ikakhulukazi ekusetshenzisweni komfutho ophakathi nendawo kanye nowezinga eliphezulu. Izinhlelo zokungenisa umoya noma zokupholisa ezanele zibalulekile.
2. Ukuzwela kokwehla kwengcindezi
Ukwehla kwamandla kagesi kokuqala kuthinta izinhlelo zokusebenza ezibucayi. Ukulungiswa nokuhlanganiswa okufanele kuyadingeka ukuze kulinganiswe ukusebenza kokuqala nezidingo zesistimu.
3. Izindleko
Iziqalisi ezithambile ze-Solid state zingabiza kakhulu kusengaphambili uma kuqhathaniswa nezinye izindlela zokuqala. Kodwa-ke, izinzuzo zazo zesikhathi eside zivame ukuthethelela ukutshalwa kwezimali. Isiphetho Iziqalisi ezithambile ze-Solid state ziyingxenye ebalulekile yesistimu yezimoto ze-AC ezisebenza ngogesi ophakathi nendawo kanye nophezulu, ezinganikeza ukuqala okubushelelezi, ingcindezi ephansi kanye nokusebenza kahle okuphezulu. Amandla azo okuzivumelanisa nezidingo ezahlukene zezimboni azenza zibe ithuluzi eliwusizo lokwenza ngcono ukusebenza kwezimoto kanye nokwandisa impilo yemishini. Njengoba ubuchwepheshe buthuthuka, ukuhlanganiswa kwemisebenzi ehlakaniphile, njengokuxhumeka kwe-iot kanye nokugcinwa kokubikezela, kuzothuthukisa kakhulu amakhono azo, kuzenze zibe ezibalulekile ezimweni zezimboni zanamuhla.
