Amakuru yibanze yabakoresha
Isosiyete izunguruka ibyuma ikora cyane cyane ibyuma bizunguruka bishyushye hamwe na 16mm ~ φ150mm.Igice cyingufu zumurongo wumusaruro wikigo gitwarwa na moteri ya DC kandi ifite moteri ebyiri 3150KVA.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:
Amakuru yimikorere
Impuzandengo yingufu za moteri ya 3150KVA DC idafite amashanyarazi ni PF = 0,75, umuyoboro wakazi ni 2650A, imiyoboro nyamukuru ni inshuro 5, inshuro 7, naho igipimo cyo guhindura ni 19.5%.
Isesengura rya Sisitemu
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.
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, akayunguruzo k'ingufu zigomba gutegurwa kuri 250Hz, 350Hz hamwe nizindi nteruro kugirango harebwe niba umuzunguruko w’indishyi zishobora gushungura neza amashanyarazi asohoka, kunoza ibintu, no gutuma sisitemu ya pulse ikurikiza GB / T3 .
umukoro
Imbaraga zuzuye za transformateur ya 3150KVA yishyurwa kuva 0,72 kugeza kuri 0.95.Ibikoresho byo kuyungurura bigomba gushyirwaho hamwe na 2100KVar, hanyuma bigabanijwemo amatsinda 6 yo kugenzura kugirango yishyure uruhande rwo hasi rwumuvuduko wa transformateur, hanyuma uhindure amajwi kuri 95KVAR, hitawe kubisabwa ingufu ziva kumurongo.
Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri Mata 2011, hashyizweho icyuma cya moteri ya DC cyungurura amashanyarazi kandi gishyirwa mu bikorwa.Igikoresho gihita gikurikirana impinduka zumutwaro wa moteri ya DC, kandi mubyukuri muyungurura ibintu byo murwego rwohejuru kugirango byishyure imbaraga zidasanzwe kandi bitezimbere imbaraga.ibisobanuro nkibi bikurikira:
Igishushanyo mbonera cya Harmonic
Umutwaro Waveform
Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, imbaraga zo guhindura umurongo zigera kuri 0,98 (igice cyazamutse ni 0.7 mugihe igikoresho cyo kwishyura cyayungurujwe)
Imikorere
Imbaraga zingufu za transformateur 3150KVA ziri hejuru ya 0,95, ihuriro rya 5 ryaragabanutse riva kuri 510A rigera kuri 102A, ihuriro rya 7 ryaragabanutse riva kuri 300A rigera kuri 60A, naho ikoreshwa ryaragabanutse kuva 2650A kugeza 2050A, igabanuka rya 23%.Nyuma yindishyi, kugabanya ingufu zamashanyarazi ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 35 × {(0,72 × 3150) / 3150} 2 × 0.66≈33 . amasaha ku munsi, iminsi 30 ku kwezi, n'amezi 10 mu mwaka, 0.7 Yuan kuri kilowatt-isaha y'amashanyarazi);kubera kugabanuka kwimiterere, fagitire yamashanyarazi yazigamye: Igihombo cya transformateur iterwa numuyoboro uhuza cyane cyane ni ukongera igihombo cya ferromagnetic no gutakaza umuringa.Igihombo cya ferromagnetiki gifitanye isano nimbaraga za gatatu zihuza inshuro zingana.Ubwubatsi Mubisanzwe, 2% ~ 5% byafashwe.Ku mutwaro wo gukosora, hafashwe 2%, ni ukuvuga WS = 4300 * 6000 * 0.7 * 0.03≈360.000, ni ukuvuga ko kuzigama buri mwaka amafaranga y’amashanyarazi ari 28 + 36 = 64 (10,000 10,000).
ibintu byimbaraga
Muri rusange uburenganzira bw’isosiyete bwiyongereye kuva kuri 0,72 bugera kuri 0.95, uburenganzira bw’ukwezi bwagumye kuri 0.96-0.98, kandi umushahara wa buri kwezi uva ku mafaranga arenga 100.000 ugera ku 15.000.
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 zamashanyarazi ya DC idafite amashanyarazi, kandi izamenyekanisha abakiriya bamwe mugihe kizaza.
