Abahlinzeki bemishini yokulondoloza amandla e-Elevator bakukhumbuza ukuthi ukusetshenziswa kwamandla okuyinhloko kwamakheshi kudluliselwa kusuka kugridi yamandla kuya ku-motor kagesi ngokusebenzisa ama-rectifiers, ama-capacitor amabhasi, ama-inverters, njll. Ngokombono, ama-elevator achitha ingxenye yesikhathi sawo ekhiqiza ugesi, echitha cishe i-40% yamandla aphelele. Indlela yokugaywa kabusha nokusebenzisa la mandla isiphenduke inkomba ekhethwayo yokongiwa kwekheshi.
Uma injini kagesi isesimweni sokuphehla (okungukuthi lapho ilifti lehla nelenyuka ngendlela engalingani noma yehla isiya esiteshini), amandla azonqwabelana ku-capacitor yebhasi, akhiqize amandla omthamo wephampu. Uma la mandla engasetshenzisiwe ngesikhathi, amaphutha e-overvoltage azokwenzeka, okuzosongela ukuphepha kwesistimu yokulawula i-elevator.
Njengamanje, amakheshi asetshenziswa emakethe (ngaphandle kwamakheshi anesivinini esikhulu angenisiwe, athatha cishe u-2% wengqikithi) aphatha la mandla ngokwengeza amayunithi okubhuleka nama-resistors amabhuleki, futhi amoshe la mandla kagesi kuma-resistors njengamandla okushisa.
Uma i-elevator ibhuleka njalo noma kaningi esimweni esingalingani, ngeke nje ibangele ukumosha amandla okukhulu, kodwa futhi iholele ekushiseni kokumelana, okubangela ukuba izinga lokushisa elizungezile likhuphuke.
Ngenxa yemvelo ekhethekile yamakheshi, ukushisa okukhiqizwa ngama-resistors kuphezulu kakhulu, futhi izinga lokushisa lasendaweni lezinto eziphikisayo ngokuvamile lingaphezu kuka-100 ℃. Ukuze unciphise izinga lokushisa ekamelweni lomshini ekamelweni lokushisa futhi uvimbele ama-elevator ukuthi angasebenzi kahle ngenxa yokushisa okuphezulu; Abasebenzisi badinga ukufaka ama-air conditioner noma amafeni anevolumu ephezulu yokukhipha umoya; Emakamelweni emishini anamandla aphezulu e-elevator, ngokuvamile kudingekile ukusebenzisa isimo somoya kanye namafeni ngesikhathi esisodwa, noma ukuqalisa ama-air conditioning amaningi namafeni ngesikhathi esisodwa. Lokhu akubangeli nje ukumosheka kwamandla okukhulu kumakheshi, kodwa futhi kwandisa ukusetshenziswa kwamandla kwemishini yokupholisa.
Izimiso nezikhombisi-ndlela zokuvuselela ukonga amandla kwamakheshi
Ukugxila kokulungiswa kufanele kube ukuqinisekisa ukuphepha, ukunethezeka, nokusebenza kahle ngenkathi kunciphisa ukusetshenziswa kwamandla. Umgomo wenguquko uthi:
1. Ukungashintshi umphumela wokusetshenziswa, okungukuthi, akuthinti ukusebenza okuvamile kwekheshi;
2. Ugesi ngeke umoshwe futhi ungasetshenziswa kabusha;
3. Ukushisa kwegumbi kuyehla, futhi ehlobo, isimo somoya singavalwa, noma okungenani izinga lokushisa akufanele libe phansi kakhulu;
4. Isistimu evuselelwe kufanele kube lula ukuyisebenzisa nokuyinakekela.
Idivayisi yempendulo yamandla ekheshi iyiyunithi yokubhuleka impendulo esebenza kahle kakhulu eklanyelwe amakheshi. Ingakwazi ukuguqula ngempumelelo amandla kagesi avuselelwe agcinwe ku-capacitor ye-elevator frequency converter ibe amandla e-AC futhi iwathumele emuva kugridi yamandla, iguqule ilifthi ibe "isikhungo samandla" esiluhlaza ukuze sinikeze amandla kwezinye izisetshenziswa. Inomsebenzi wokonga ugesi, ngokusebenza kahle okonga kukagesi okungama-20-50% kanye nokusebenza kahle kokuvuselela amandla kagesi okufika ku-97.5%. Ukwengeza, ngokushintsha ama-resistors ukuze kusetshenziswe amandla, izinga lokushisa elizungezile ekamelweni lomshini liyancishiswa, futhi izinga lokushisa lokusebenza lesistimu yokulawula i-elevator liyathuthukiswa, kunwetshwe impilo yesevisi ye-elevator. Igumbi lomshini alidingi ukusetshenziswa kwezinto zokupholisa ezifana ne-air conditioning, ukonga ugesi ngokungaqondile.
