Amakuru yibanze yabakoresha
Isosiyete ikora ibicuruzwa bya pulasitike ikora cyane cyane mu nzu no hanze yamamaza igitambaro cyamatara yoroheje, igitambaro cyo gutera, hamwe n’ibicuruzwa bya firime bya PVC.Ibikoresho byo gukora uruganda bifite ubugari bune bugari bwa PVC buzengurutse imirongo yerekana amashusho, hamwe numurongo wo gutunganya spray hamwe numurongo wibikoresho bikoresha amafoto, Igice cyamashanyarazi gikoresha moteri ya moteri ya moteri na moteri ya DC, 1000KVA, amaseti 2 ya 1250KVA, 2 ibice bya 800KVA bihindura, 1 set ya 630KVA ihinduranya, hamwe nicyapa cyindishyi zubushobozi gishyirwa kuruhande rwa voltage ntoya ya transformateur.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:
Amakuru yimikorere
Transformator ya 2000KVA ifite itanura rinini hagati na inverter ifite ingufu ntarengwa za 1500KVA, ibintu bifatika ni PF = 0.82, amashanyarazi akora ni 2250A, guhuza cyane cyane ni 5 na 7, kandi igipimo cyo kugoreka ubu ni 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.

Buri seti ya 2000KVA ihinduranya ihuye nitanura ryigihe gito kandi imbaraga zuzuye za inverter zishyurwa kuva 0.8 kugeza hejuru ya 0.95, ihuriro rya 5 ryaragabanutse riva kuri 420A rigera kuri 86A, naho ihuriro rya 7 ryaragabanutse riva kuri 230A rigera kuri 46A.Igikoresho cyo kuyungurura ibikoresho bigomba gushyirwaho bifite ubushobozi bwa 1060KVar.Igabanijwe mu matsinda 6 yubushobozi bwo guhinduranya byikora, bihuye n’itanura rito hagati, inverter rectifier power supply filter filter, igabanijwemo inshuro 5, inshuro 7 hamwe nindishyi nziza zo kuyungurura indishyi zumuhanda umuhanda uhinduranya, kugirango uhure nitanura rya interineti hagati, filteri ya inverter na imbaraga zidasanzwe Ibishushanyo mbonera bisabwa.
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 ku gishushanyo gikurikira: Isesengura ryingaruka 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:

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)
Imiterere yimikorere yimikorere Ikoreshwa na buri seti ya 2000KVA ihinduranya igabanuka kuva 2250A ikagera 1860A, igabanuka rya 17%;agaciro kagabanutse gutakaza ingufu nyuma yindishyi ni WT = △ Pd * (S1 / S2) 2 * τ * [1- (cosφ1 / cosφ2) 2] = 24 × {(0.85 × 2000) / 2000} 2 × 0.4≈16 . , Iminsi 30 ku kwezi, n'amezi 10 mu mwaka, 0.7 Yuan kuri kilowatt-isaha y'amashanyarazi);fagitire y'amashanyarazi yazigamye kubera igabanuka ry'imiterere: Igihombo cyatewe numuyoboro uhuza imiyoboro ihinduranya ahanini biterwa no kwiyongera kwa ferromagnetiki no gutakaza umuringa no gutakaza ferromagnetique bifitanye isano nimbaraga za gatatu zumurongo uhuza.Mubisanzwe, 2% ~ 5% bifatwa mubuhanga, naho 2% bifatwa kugirango bikosorwe, aribyo: WS = 2000 * 6000 * 0.7 * 0.02≈168.000 yuan, ni ukuvuga ko fagitire yamashanyarazi ishobora kuzigama mumwaka wose (6.7 + 16.8) * 2 = 47 (10,000 Yuan).
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.
