Uruganda rukora ibyuma

Amakuru yibanze yabakoresha
Uruganda rwibanze rwibyuma nibikoresho byubaka uruganda rukora neza ibyuma bya PC bizunguruka, amasahani yanyuma, imirongo ya galvanis, imirongo yibikoresho yahinduwe, 30MnSi nibindi bicuruzwa.Isosiyete ifite imirongo 4 nziza yumusaruro, ikoresha ubushyuhe buringaniye bwo gushyushya hamwe na moteri ya DC ihindagurika ya moteri, hamwe na 2000KVA2 (ikoreshwa muri tandem).Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:

Amakuru yimikorere
Imbaraga zihariye ni PF = 0.82, amashanyarazi akora ni 2250A, imiyoboro nyamukuru ya pulse inshuro 5, naho igiteranyo cyose kiba 23,6%.

Isesengura rya Sisitemu Yimbaraga
Umutwaro nyamukuru w itanura ryigihe cyo hagati, itanura ryigihe cyo hagati hamwe na inverter ikosora amashanyarazi ni 6 ya pulse ikosora.Ibikoresho byo gukosora bitanga ingufu nyinshi za pulse mugihe uhinduye AC amashanyarazi muri voltage ya AC.Umuyoboro uhuza winjiye mumashanyarazi urashobora gutera pulse Umuyoboro wogukora wubu, bikavamo ihindagurika ryumubyigano wamashanyarazi numuyoboro, bigahungabanya ubuziranenge numutekano wibikorwa byo guhinduranya amashanyarazi, kongera umurongo wumurongo no gutandukanya amashanyarazi, kandi bikagira ingaruka mbi kumurongo wamashanyarazi kandi ibikoresho by'amashanyarazi by'amashanyarazi ubwayo.
Porogaramu igenzura porogaramu ya mudasobwa (PLC) yunvikana kugoreka guhuza imbaraga za voltage yumurimo wo gutanga amashanyarazi.Mubisanzwe biteganijwe ko igiteranyo cyimikorere yimikorere ya voltage ikorwa (THD) iri munsi ya 5%, hamwe na pulse kugiti cyumubyigano wakazi Niba igipimo cyikigero kiri hejuru cyane, ikosa ryimikorere ya sisitemu yo kugenzura rishobora gutuma habaho ihagarikwa rya umusaruro cyangwa imikorere, bikaviramo impanuka nini yumusaruro.Kubwibyo, imbaraga nke za voltage yingufu zamashanyarazi zungururwa hamwe numurimo wa pulse ya filteri ikwiye gukoreshwa kugirango yishyure imitwaro yoroheje kandi itezimbere imbaraga.

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, isosiyete yateguye gahunda irambuye y’indishyi z’amashanyarazi ku itanura rito hagati y’amashanyarazi no gutanga amashanyarazi.Urebye ibintu bitwara imizigo hamwe na pulse yubu iyungurura, Gushiraho akayunguruzo gake-voltage yingufu zingirakamaro, gushungura impanuka ya pulse, kwishyura imitwaro ikora, no kunoza ibintu byingufu.
Mubikorwa byose byo gutanura hagati yigihe cyo kwinjiza no guhinduranya, ibice byose bibyara 6K pulse ya pulse, ihindurwa ukurikije imigendekere yuruhererekane rwa Fourier, kandi imiyoboro iranga pulse ikorwa kuri 5250Hz na 7350Hz.Kubwibyo, mugihe utegura akayunguruzo k'ingufu zitangirwa ingufu, gahunda yoroshye yo gutangiza na 350Hz igishushanyo mbonera cyerekana ko amashanyarazi yungurura amashanyarazi atangwa neza kandi akayunguruzo kayunguruzo kayunguruzo kongerwaho kunoza ibintu kugirango amashanyarazi agabanuke bijyanye na GB / T3 bose hamwe.

umukoro
Icyuma gitangira cyoroshye kandi cyoroshye cyo gutangiza imbaraga za buri tsinda rya 2000KVA zihindura indishyi ziva kuri 0.8 kugeza 0.95, umuyoboro wa 5 wa pulse wagabanutse uva kuri 420A ugera kuri 86A, umuyoboro wa 7 wa pulse wagabanutse uva kuri 230A ugera kuri 46A, kandi ibikoresho byindishyi zungurura shyiramo nubunini bwa 1060KVar.Akayunguruzo kagabanijwe mu matsinda 6, indishyi zungururwa zikoreshwa mugutangira byoroshye no guhinduranya amashanyarazi ya ballast, akayunguruzo kagabanijwemo inshuro 5, inshuro 7, kandi amashanyarazi yo gutanga amashanyarazi azunguruka ahita ahindurwa kugirango harebwe itanura ryigihe gito. , Akayunguruzo na reaction yingirakamaro Igishushanyo mbonera cya gahunda yo kwishyura.
Igishushanyo cyemeza neza ko igenzura rihuza ryujuje ubuziranenge bwigihugu GB / T 14549-93, kandi rigahindura ibintu byingufu zamashyiga aringaniye hamwe na enterineti ihindura 0.95.Nkuko bigaragara hano hepfo:

Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri kamena 2010, hashyizweho itanura rito hagati yumurongo wa interineti hamwe na enterineti ihinduranya ibikoresho byishyurwa byingufu zishyurwa kandi bigashyirwa mubikorwa.Igikoresho gihita gikurikirana impinduka zumutwaro hagati yumuriro wa interineti nigihe cyo guhinduranya, kandi mubyukuri ikuraho ibyateganijwe murwego rwo hejuru kugirango yishyure imbaraga zidasanzwe kandi zitezimbere imbaraga.ibisobanuro nkibi bikurikira:

Igishushanyo mbonera cya Harmonic

Umutwaro Waveform

Nyuma yo gushungura ibikoresho byungururwa bimaze gukoreshwa, imbaraga zimpinduka zumurongo nyuma yigikoresho cyo kuyungurura amashanyarazi kimaze gukoreshwa ni 0.97 (igice cyazamutse ni 0.8 mugihe igikoresho cyo kwishyura cyayungurujwe)

Imikorere
Kugeza ubu ikoreshwa na buri seti ya 2000KVA ihinduranya igabanuka kuva 2250A ikagera kuri 1860A, igabanuka rya 17%;nyuma yindishyi, igiciro cyo kugabanya ingufu ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 24 × {(0.85 × 2000) / 2000} 2 × 0.4≈16 . umunsi, iminsi 30 mu kwezi, amezi 10 mu mwaka, 0.7 Yuan kuri kilowatt-isaha);fagitire y'amashanyarazi yazigamye kubera kugabanuka guhuza: Igihombo cyatewe numuyoboro uhuza na transformateur ahanini ni ukongera igihombo cya ferromagnetic no gutakaza umuringa, Igihombo cya ferromagnetiki gifitanye isano nimbaraga za gatatu zumurongo uhuza.Mubisanzwe, 2% ~ 5% bifatwa mubuhanga, naho 2% bifatwa kumitwaro ikosowe, aribyo: WS = 2000 * 6000 * 0.7 * 0.02≈168,000 yuan, ni ukuvuga kuzigama amashanyarazi yumwaka (6.7 + 16.8) * 2 = 47 (10,000).

ibintu byimbaraga
Muri rusange uburenganzira bw’isosiyete bwongerewe kuva kuri 0.8 bugera kuri 0.95, kandi uburenganzira bwa buri kwezi bwagumishijwe kuri 0.96-0.98, hiyongereyeho amafaranga 6.000-10,000.
Muri rusange, amashanyarazi make ya voltage yingufu za MFF na VF muyunguruzi afite akayunguruzo keza kandi yishyura imitwaro yoroheje, ikemura ikibazo cyibihano byamashanyarazi, byongera ubushobozi bwumusaruro wa transformateur, bizamura ubwiza bwamashanyarazi, bizamura ibiranga amashanyarazi akoreshwa ibikoresho, kandi bigabanya indishyi zingufu zikoreshwa Gukoresha, kuzamura imikorere, inyungu zingenzi mubukungu kuri sosiyete, ishoramari hamwe ninyungu itarenze umwaka kubakiriya, nibindi. n'iyungurura reaction yumutwaro wa inverter itanga amashanyarazi, kandi izamenyekanisha abakiriya benshi mugihe kizaza.
