Amakuru yibanze yabakoresha
Isosiyete izunguruka ibyuma ikora iminyururu ya 0.5mm.Isosiyete ifite imirongo 4 itanga umusaruro, harimo 1 kuri 650 zibyuma na 3 kumashini 450.Imbaraga zo gutwara zitwarwa igice na moteri ya DC idafite amashanyarazi, hamwe na 3 ya 1250KVA ya transformateur na 630KVA..Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:
Amakuru yimikorere
Impuzandengo yingufu za 1250KVA zihindura ni PF = 0,62, umuyoboro wakazi wa 1960A na 630KVA uhindura ni 700KVA, impuzandengo yingufu ni PF = 0,62, amashanyarazi akora ni 1050A, abahindura bose bafite ibiro byinshi, na pulse ya pulse ni inshuro 5, igipimo cyo guhindura ingano ni 18.5%.
Isesengura rya Sisitemu Yimbaraga
Umutwaro nyamukuru wa DC brushless moteri ballast ni 6 ballasts imwe.Ibikoresho bya ballast bibyara umubare munini wimikorere ya AC, AC, na DC.Nibisanzwe pulse isanzwe.Iyo byinjijwe mumashanyarazi, imiyoboro ihuza imiyoboro ya pulse yumuvuduko wamashanyarazi iterwa no kuranga imiyoboro yumuriro w'amashanyarazi, bikavamo hanze-yumurongo wa voltage ikora numuyoboro, ibyo bikaba byangiza umutekano nibikorwa byumutekano yo guhinduranya amashanyarazi, kongera umurongo gutakaza no gukora voltage ikora, kandi bigira ingaruka mbi kumurongo wamashanyarazi nibikoresho byamashanyarazi ubwabyo.Kubwibyo rero, indishyi za moteri ya DC idafite amashanyarazi igomba gukoresha ingufu zidafite ingufu zingana n’amashanyarazi ya pulse yamashanyarazi kugirango yishyure imitwaro ikora, itezimbere ingufu, kandi ntabwo izahanwa nimbaraga zidasanzwe kugirango yongere umusaruro wa transformateur .
Shungura gahunda yo kuvura amashanyarazi
Intego z'imiyoborere
Igishushanyo cyibikoresho byindishyi zujuje ibyangombwa bisabwa byo guhagarika guhuza no gucunga ingufu zidasanzwe.
Munsi ya 0.4KV ya sisitemu yo gukora, nyuma yo kuyungurura ibikoresho byindishyi zashyizwe mubikorwa, impanuka ya pulse irahagarikwa, kandi impuzandengo yingufu zingana buri kwezi ni 0.92.
Urwego rwohejuru ruhuza resonance, resonance overvoltage, hamwe na overcurrent iterwa no guhuza na filteri yindishyi zishami ntizizabaho.

Gutegura ibitekerezo
Ukurikije uko ibintu byifashe muri iyi sosiyete, hateganijwe gahunda y’indishyi z’amashanyarazi ya DC idafite amashanyarazi yashyizweho hifashishijwe urebye ibintu bitwara imizigo ndetse no guhagarika impanuka, kandi hashyizweho akayunguruzo k’amashanyarazi gafite ingufu nkeya zishyirwa munsi ya 0.4kV voltage uruhande rwa transformateur, kugirango uhagarike impanuka ya pulse, kandi yishyure imitwaro itagaragara, kandi itezimbere imbaraga.Ballast itanga 6K-1 pulse yumuvuduko mugikorwa cya moteri ya DC idafite amashanyarazi, kandi ikoresha umuyoboro wa casade kugirango ushongeshe umuyaga, kandi umuyaga ushonga ni nka 5250Hz na 7350Hz.Kubwibyo rero, igishushanyo mbonera cy’indishyi zishushanya hagati y’itumanaho rya interineti rigomba gufata 250Hz, 350Hz hamwe nigishushanyo mbonera nkintego, kugirango harebwe niba ishami ryindishyi ziyungurura rishobora guhagarika neza indishyi zubu, kandi kuri kimwe. umwanya uhagarike umutwaro udasanzwe kandi utezimbere Imbaraga.
umukoro
Imbaraga zuzuye zumurongo wa 12500KVA DC zidafite amashanyarazi zishyurwa ziva kuri 0.62 kugeza kuri 0.95.Ibikoresho byungururwa bigomba gushyirwaho hamwe nubunini bwa 1100KVar, bigabanijwe mumatsinda 10 yindishyi zo guhinduranya byikora kugirango yishyure umuyaga kuruhande rwa voltage yo hepfo ya transformateur.45KVAR buhoro buhoro ihindura amajwi kugirango ihuze ingufu zisabwa kumurongo wibyakozwe.Transformator ya 630KVA DC itagira moteri yumurongo wa moteri Ibintu byose byamashanyarazi byishyurwa kuva 0.62 kugeza kuri 0.95.Akayunguruzo k'indishyi kagomba gushyirwaho hamwe nubunini bwa 600KVar, hanyuma igahita ihagarika uruhande rwo hasi rwihinduranya rwa transformateur, hamwe nubunini bwayo bwahinduwe buhoro buhoro bwa 45KVAR, hitawe kubisabwa na voltage kumurongo wibyakozwe.
Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri Mata 2010, hashyizweho igikoresho cyo kwishyura amashanyarazi ya moteri ya DC cyashyizwe mu bikorwa.Igikoresho gihita gikurikirana impinduka zumutwaro wa moteri ya DC hamwe nabahinduranya inshuro nyinshi, ikabuza guhuza-murwego rwohejuru mugihe nyacyo, ikishyura imbaraga zidasanzwe, kandi igateza imbere imbaraga.ibisobanuro nkibi bikurikira:
Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, imbaraga zimpinduka zingaruka zingana ni 0,99 (igice cyazamutse ni 0,6 mugihe igikoresho cyo kwishyura cyayungurujwe)
Imikorere
Kugeza ubu ikoreshwa na transformateur ya 1250KVA yagabanutse kuva 1960A igera kuri 1210A, igabanuka rya 38%.Kugeza ubu ikoreshwa na transformateur ya 1630KVA yagabanutse kuva 1050A igera kuri 657A, igabanuka rya 37.5%.Nyuma yindishyi, kugabanya igihombo cyamashanyarazi ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 32 × {(0.62 × 3000) 3000} 2 × 0.4≈15.8 ( kw · h) Muri formula, Pd nigihombo gito cyumuzunguruko wa transformateur, ni 32KW, kandi kuzigama buri mwaka amafaranga yakoreshejwe ni 15.8 * 10 * 30 * 10 * 0.7 = 33.000 yuan (hashingiwe kumasaha 20 a umunsi, iminsi 10 ku kwezi, n'amezi 10 mu mwaka, kuri kwh amashanyarazi 0.7 Yuan).
ibintu byimbaraga
Muri rusange uburenganzira bw’isosiyete bwiyongereye kuva kuri 0.7 bugera kuri 0.95, uburenganzira bw’ukwezi bwagumye kuri 0.96-0.98, naho umushahara wa buri kwezi ni 3.000-4,000.
DC ya filteri ya moteri ya voltage yumuriro wamashanyarazi ifite ubushobozi bwo guhagarika impanuka ya pulse no kwishyura imitwaro yumuriro, gukemura ikibazo cyibihano byamashanyarazi, kongera ubushobozi bwumusaruro wa transformateur, kugabanya igihombo cyindishyi zikomeye, kongera umusaruro, no guha Isosiyete yatanze inyungu zubukungu zikomeye, kandi umukiriya yabonye igishoro cyumushinga mugihe kitarenze umwaka.Kubwibyo, isosiyete yishimiye cyane indishyi zingufu za moteri ya DC idafite amashanyarazi na filteri ya inverter, kandi izamenyekanisha abakiriya bamwe mugihe kizaza.
