Ngenxa yethonya le-rotor slip-ring, isivinini se-cascade elawula i-motor ayikwazi ukuthola amandla amakhulu kanye nomsebenzi wokulungisa we-slip-ring nawo mkhulu.

Uhlobo lwamanje lomthombo oluqondile oluqondile lwe-voltage ephezulu

I-inverter yamukela i-thyristor ohlangothini lokokufaka ukuze ilungiswe, isitoreji samandla e-inductive, kanye ne-SGCT ohlangothini lwe-inverter njengento yokushintsha, okuyisakhiwo sendabuko esinamazinga amabili.Ngenxa yezinga lokucindezela elilinganiselwe ledivayisi, amadivayisi amaningi kufanele asetshenziswe ochungechungeni.Ukuhlelwa kwedivayisi kuwuhlelo lonjiniyela oluyinkimbinkimbi kakhulu olunokwethenjwa okuphansi kwethiyori, kodwa ezinye izinkampani zingafinyelela ekukhiqizeni.Njengoba kunamaleveli amabili kuphela ohlangothini lokuphumayo, i-dv/dt ethwalwa injini yamandla kagesi Ephakeme inkulu, ngakho-ke isihlungi esiphumayo kufanele samukelwe.I-multi-pulse rectifier ohlangothini lwegridi yamandla uyazikhethela futhi umsebenzisi udinga ukwenza izidingo ngokuya ngesimo sakhe sasembonini.Inzuzo eyinhloko yalesi siguquli ukuthi singakwazi ukondla amandla angenayo okulayisha emuva kugridi ngaphandle kokujikeleza okwengeziwe.

Okubi okuyinhloko kwe-inverter yomthombo wamanje yisici samandla aphansi, i-harmonic ephezulu, noshintsho ngokushintsha kwesimo sokusebenza.

I-3. Cubufebe

i-high-voltage-proof motor-proof motor sebenzisa izivalo ezingashi ukuze zihlukanise izingxenye zikagesi ezingase zikhiqize izinhlansi, i-arc, namazinga okushisa ayingozi kungxube yegesi eqhumayo. Kodwa-ke, indawo ebiyelwe ayivalwanga kahle, futhi ingxube yegesi eqhumayo ezungezile ingase ingene enjini yamandla kagesi aphezulu ngegebe eliphakathi kwezindawo zokukhwelana zezingxenye ezivalekile. Ukuqhuma kungase kwenzeke uma kuhlangana nemithombo yokuthungela efana nenhlansi, i-arc nezinga lokushisa eliphakeme eliyingozi ngaphakathi kwendawo ebiyelwe.

Ngalesi sikhathi, indawo evalekile yenjini ye-High voltage ngeke yonakale noma yonakale, futhi ilangabi eliqhumayo noma igesi eshisayo ngeke ithungele ingxube yegesi eqhumayo lapho idlula igebe lendawo ebophayo.

Sumarize

Kunezinhlobo eziningi zamamotho angaqhumi. Endaweni eyingozi yokuqhuma, ukukhethwa kwezinjini ezingaqhumi kubaluleke kakhulu ukuze kuqinisekiswe ukukhiqizwa okuphephile. Lapho ukhetha injini yokuvikela ukuqhuma, ukusebenza kokuvikela ukuqhuma kufanele kuqondwe. Kuphela ngokukhetha injini efanele yokuvikela ukuqhuma lapho ukuphepha kokusetshenziswa kungaqinisekiswa khona futhi akukho kumoshwa kwezinsiza
