Ikibanza cyo gutunganya imyanda

Amakuru yibanze yabakoresha
Ikintu cyingenzi cyo gutunganya imyanda yo mu rugo y’isosiyete itunganya amazi y’amazi, igice cyo gutanga amashanyarazi igice cyumurongo utunganya amazi y’amazi gikoresha moteri ya DC ihindagurika ya moteri, hamwe na 1000KVA2, 630KVA.Igishushanyo cya sisitemu yo gutanga amashanyarazi niki gikurikira:

Amakuru yimikorere
Imbaraga zisohoka za 1000KVA transformateur yoroshye itangira ni 860KVA, impuzandengo yingufu ni PF = 0.83, amashanyarazi akora ni 1250A, amashanyarazi akora ni 630KVA, ingufu ni PF = 0.87, naho amashanyarazi ni 770A.Imbaraga zose rero zishobora kuba 0.84 gusa.

Isesengura rya Sisitemu Yimbaraga
Umutwaro nyamukuru wa ballast ihindura ni 6-imwe ya pulse.Ibikoresho bya ballast bitanga umusaruro mwinshi wa pulse mumurimo wo guhindura AC kuri DC.Nibisanzwe pulse isanzwe kandi ni iyinjiza mumashanyarazi.Imiyoboro ya Harmonic itera imbaraga zumubyigano wamashanyarazi kumurongo uranga amashanyarazi, bikaviramo gutakaza imbaraga zumuriro wumuriro numuyoboro, bigahungabanya ubuziranenge nibikorwa byoguhindura amashanyarazi, kongera umurongo wumurongo no gutandukana kwumuriro, kandi bigatera ingaruka mbi kuri amashanyarazi n'amashanyarazi ubwabyo Ingaruka.
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 zidafite imbaraga zo kwishura amashanyarazi hamwe na pulse yimikorere yo guhagarika ibikorwa bigomba gukoreshwa kugirango uhagarike impanuka ya sisitemu, indishyi zikorera, kandi zitezimbere 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 imiterere yihariye yikigo, hashyizweho gahunda yindishyi zingufu zamashanyarazi kumashanyarazi ya inverter yerekana neza ibintu bitwara imizigo hamwe no guhagarika impanuka ya pulse byateguwe, kandi hashyizweho akayunguruzo gashiramo ingufu nkeya kuri voltage ya 0.4kV yo hasi. uruhande rwa transformateur yisosiyete Indishyi zingufu zoguhagarika impyisi, kwishyura imitwaro idahwitse, no kunoza ibintu byamashanyarazi.
Ballast itanga 6K-1 itondekanya pulse mugihe cyo gukora, kandi ikoresha kode yamababi ikurikiranye hafi 5250Hz na 7350Hz kugirango ikore ihinduka.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 1000KVA uhindura imirongo yishyurwa kuva 0.8 kugeza kuri 0.95.Ibikoresho byo kuyungurura bigomba gushyirwaho hamwe nubunini bwa 380KVar, igabanijwemo amatsinda ane, buri imwe ihita ifunga kandi igacibwa, ikishyura ibyangiritse byumuvuduko wuruhande rwa voltage yo hepfo ya transformateur, kandi ifite intambwe yo guhindura intambwe. ya 45KVAR, ishobora kwinjizwa mubisabwa ingufu zumurongo wumurongo.Imbaraga zuzuye zishyurwa kuva 0.8 kugeza 0.95.Ibikoresho byo kuyungurura byungururwa bigomba gushyirwaho nubunini bwa 310KVar, kandi amatsinda ane ahita ahagarikwa kugirango yishyure uruhande rwo hasi rwa transformateur, hanyuma amajwi ahindurwa kuri 26KVAR kugirango yuzuze ibisabwa na voltage yumurongo wibyakozwe.

Isesengura ryingirakamaro nyuma yo kwishyiriraho indishyi
Muri Kanama 2010, hashyizweho ibikoresho byungurura ingufu za inverter zungurura ingufu hanyuma bishyirwa mubikorwa.Igikoresho gihita gikurikirana impinduka zumutwaro wa inverter, kigahagarika imiterere-yo murwego rwohejuru mugihe nyacyo, ikishyura imbaraga zidasanzwe, kandi igateza imbere 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)
