Ukusetshenziswa kwamandla kwamathuluzi omshini we-CNC kunqunywa ngokuqondile amandla emoto ethuluzi lomshini kanye nesikhathi sokusebenza esiqhubekayo sethuluzi lomshini, kuyilapho isikhathi esiqhubekayo sokusebenza samathuluzi omshini we-CNC sinqunywa izimo zokusebenza zethuluzi lomshini, okungukuthi imvamisa yokumisa yokuqala, isikhathi sokusheshisa, isikhathi sokucubungula, nesikhathi sokuvala. Ngakho-ke, sibala ukusetshenziswa kwamandla ngokusekelwe emandleni, isikhathi sokusebenza, kanye ne-coefficient yesimo sokusebenza sethuluzi lomshini we-CNC.
3, Isingeniso Somkhiqizo Sedivayisi Yempendulo Yokonga I-IPC-PGC Sine Wave
Idivayisi yempendulo yokonga amandla ye-IPC-PGC sine wave iwumkhiqizo owonga amandla onomsindo omncane okhiqizwe kusetshenziswa ubuchwepheshe baseCanada, obusebenzisa ama-algorithms athuthukisiwe ukuze kuzuzwe impendulo ephelele yamandla e-sine wave. Ingabuyisela amandla kagesi avuselelwe akhiqizwa ngesikhathi senqubo yokulawula isivinini semoto kugridi yamandla, igweme ukulahlekelwa amandla okubangelwa amayunithi amabhuleki adla amandla avamile kanye nokuzuza imiphumela yokonga amandla. Umkhiqizo wedivayisi yempendulo yokonga amandla we-PGC sine wave ufakwe izinto ezisabelayo nezihlungi zomsindo ngaphakathi, ezingaxhunywa ngokuqondile kugridi yamandla ngaphandle kokubangela ukuphazamiseka kugridi yamandla nezinto zikagesi ezizungezile.
Njengamanje, isetshenziswe kabanzi kumathuluzi omshini we-CNC, izinhlelo zokulawula i-servo nezinye izikhathi.
Lapho i-spindle yethuluzi lomshini we-CNC noma isistimu yokulawula i-servo ibhuleka ngokushesha, injini kagesi izoba sesimweni sokukhiqiza amandla kabusha. Ama-diode ayisithupha ku-inverter aguqula amandla emishini omshini wokudlulisa abe amandla kagesi futhi awanike amandla abuyele kusekethe ye-DC emaphakathi, okubangela ukwanda kwamandla kagesi ku-capacitor yokugcina amandla. Ukuze kuzuzwe impendulo yamandla kagesi avuselelwayo ukusuka kusimo sokubhuleka senjini ukuya kugridi, isiguquli esiseceleni kwegridi kufanele sisebenzise isiguquli esibuyiseleka emuva. Idivayisi yempendulo ye-IPC-PGC yamandla eyethulwe yi-Jianeng Company isebenzisa ibhodi lokuqaphela i-voltage yegridi enemodi yokulawula ye-PWM. Ngenxa yokusetshenziswa kobuchwepheshe bokulawula be-PWM, ubukhulu nesigaba se-voltage ye-AC ohlangothini lwegridi kungalawuleka, okungenza okokufaka kwe-AC kube okwamanje esigabeni nge-voltage yegridi futhi kusondele kumagagasi e-sine. Isici samandla sesistimu yokudlulisa sikhulu kuno-0.96, futhi inamandla wempendulo yegridi engu-100% ngesikhathi sokubhuleka impendulo ngaphandle kwesidingo se-autotransformer.
Idivayisi yempendulo yamandla kagesi ye-IPC-PGC ingabuyisela amandla kagesi avuselelwe akhiqizwa ngesikhathi sokulawulwa kwesivinini semoto nezinye izinqubo kugridi yamandla, igweme ukulahlekelwa amandla okubangelwa ukushisisa ukumelana kusetshenziswa amayunithi okubhuleka adla amandla avamile, ngaleyo ndlela kuzuzwe imiphumela efanelekile yokonga amandla kanye nokusebenza kahle.
Lapho injini isebenza endaweni ekhiqizayo, amandla kagesi akhiqizwa injini ageleza abuyele ebhasini le-DC ngokusebenzisa i-diode ohlangothini lwe-inverter. Lapho amandla kagesi e-DC edlula inani elithile, idivayisi yempendulo yamandla kagesi ye-IPC-PGC izoqala, ihlehlise i-DC ibe yi-AC, futhi ibuyisele amandla kagesi kugridi ngokulawula isigaba sikagesi kanye nobukhulu bedivayisi yempendulo yamandla kagesi, kufinyelele umgomo wokonga amandla.
Izici zobuchwepheshe eziyinhloko zedivayisi yempendulo yokonga amandla we-IPC-PGC yizi:

4 ama-reactor akhelwe ngaphakathi nezihlungi, xhuma futhi udlale
I-PGC yamukela idizayini yesakhiwo edidiyelwe, enama-reactor akhelwe ngaphakathi nezihlungi, ngakho abasebenzisi akudingeki bathenge ngokwehlukana.
5 esikhundleni ngokuphelele ukubhuleka ukumelana
I-PGC ingakwazi ukufaka esikhundleni ngokuphelele ukubhuleka ukumelana, iguqule izingxenye ezidla amandla zibe yizo ezinephutha futhi yonge ngaphezu kuka-60% wesikhala sokufaka.
6. Kulula ukusebenza, kunciphisa izindleko zokufaka nokuqeqesha
Ngaphambi kokuphuma embonini, umkhiqizo ngamunye we-PGC usuvele usethiwe ngamapharamitha wobuchwepheshe ahlangabezana nezidingo ezingaphezu kuka-90%, okuwenza uxhumeke futhi udlale. Ngesikhathi esifanayo, ukuhlangabezana nezimo zokusebenza eziyinkimbinkimbi, abasebenzisi badinga kuphela ukulungisa umkhawulo wesenzo ukuze baqinisekise ukusetshenziswa okungu-100%. Ngakho-ke, ngisho noma ungeyena uchwepheshe wezobuchwepheshe, ungakwazi ukuqalisa ngokushesha ukusebenzisa i-PGC.
7. Sebenzisa amafrikhwensi egridi yomhlaba wonke ngaphandle kwemikhawulo yendawo yezinhlelo zokusebenza
Umkhiqizo we-PGC we-THD uhlangabezana namazinga okuhlunga omhlaba womhlaba; I-EMC/EMI ihlangabezana nezinga eliqinile le-EN55022 Ikilasi A; Ingasebenza ngokuzinza kumafrikhwensi egridi asuka ku-45Hz kuye ku-65Hz. Ngakho-ke, ukusetshenziswa kwemikhiqizo ye-PGC akukhawulelwe ngokuphelele yimikhawulo yendawo
