Zambiri za ogwiritsa ntchito
Kampani yogubuduza zitsulo imapanga unyolo wachitsulo wandiweyani wa 0.5mm.Kampaniyo ili ndi mizere 4 yopanga, kuphatikiza 1 kwa 650 mphero zachitsulo ndi 3 kwa makina 450 azitsulo.Mphamvu yoyendetsa imayendetsedwa ndi ma DC brushless motors, ndi ma seti atatu a 1250KVA osinthira ndi 630KVA..Chithunzi cha dongosolo lamagetsi ndi motere:
Zomwe zimagwira ntchito
Mphamvu yapakati pa thiransifoma ya 1250KVA ndi PF=0.62, thiransifoma ya 1960A ndi 630KVA ndi 700KVA, mphamvu yapakati ndi PF=0.62, yomwe ikugwira ntchito ndi 1050A, zosinthira zonse ndizolemera kwambiri, komanso kugunda kwapano. ndi nthawi 5, chiŵerengero cha kusintha kwa voliyumu panopa ndi 18.5%.
Kusanthula Mkhalidwe Wamagetsi
Katundu wamkulu wa DC brushless motor ballast ndi 6 single-pulse ballasts.Zida za ballast zimapanga kuchuluka kwamphamvu kwamphamvu pakuchita kwa AC, AC, ndi DC.Ndi gwero la pulse panopa.Ikalowetsedwa mu gridi yamagetsi, mphamvu yamagetsi yamagetsi Kuthamanga kwamagetsi komwe kumagwira ntchito kumayambitsidwa ndi vuto la netiweki yamagetsi, zomwe zimapangitsa kuti magetsi azigwira ntchito komanso apano, zomwe zimayika pachiwopsezo chachitetezo chamtundu ndi magwiridwe antchito. za magetsi osinthira, kumawonjezera kutayika kwa mzere ndi kupatuka kwamagetsi ogwirira ntchito, ndipo kumawononga maukonde amagetsi ndi zida zamagetsi zokha.Choncho, malipiro a brushless DC galimoto ayenera kugwiritsa ntchito otsika-voteji zotakasuka mphamvu chipukuta misozi kugunda panopa kupondereza fyuluta kubweza zotakasika katundu, kusintha mphamvu chinthu, ndipo sadzalangidwa ndi zotakasika mphamvu kuonjezera linanena bungwe thiransifoma. .
Sefa dongosolo lothandizira chipukuta misozi
Zolinga zaulamuliro
Mapangidwe a zida zolipirira zosefera amakwaniritsa zofunikira pakuponderezedwa kwa ma harmonic ndi kasamalidwe kamphamvu koletsa mphamvu.
Pansi pa makina ogwiritsira ntchito a 0.4KV, zida zolipirira zosefera zitayamba kugwira ntchito, kugunda kwamagetsi kumaponderezedwa, ndipo mphamvu yapakati pamwezi imakhala pafupifupi 0.92.
High-order harmonic resonance, resonance overvoltage, ndi overcurrent chifukwa cholumikizana ndi fyuluta compensation nthambi dera sizidzachitika.

Malingaliro opangira
Malingana ndi momwe kampaniyo ikukhalira, ndondomeko yobwezera mphamvu zowonongeka kwa DC brushless motor fyuluta yapangidwa poganizira za katundu wamagetsi ndi kuponderezedwa kwa pulse panopa, ndi seti ya fyuluta yotsika-voltage reactive power compensation imayikidwa pansi pa 0.4kV. voltage mbali ya thiransifoma, kupondereza kugunda kwapano, ndikubweza katundu wokhazikika, ndikuwongolera mphamvu yamagetsi.The ballast imapanga 6K-1 pulse current popanga brushless DC motor, ndipo imagwiritsa ntchito cascaded current kuti isungunuke, ndipo yosungunuka ili pafupi 5250Hz ndi 7350Hz.Choncho, zotakataka zochitira chipukuta misozi kamangidwe ka wapakatikati pafupipafupi induction ng'anjo fyuluta ayenera kutenga 250Hz, 350Hz ndi kamangidwe pafupipafupi monga chandamale, kuti kuonetsetsa kuti malipiro nthambi fyuluta akhoza bwino kupondereza kugunda panopa chipukuta misozi, ndipo nthawi yomweyo. nthawi kupondereza katundu wokhazikika ndikuwongolera Mphamvu ya Mphamvu.
ntchito yopanga
Mphamvu yokwanira ya mzere wa 12500KVA DC brushless motor imalipidwa kuchokera pa 0.62 mpaka 0.95.Zida zolipirira zosefera ziyenera kukhazikitsidwa ndi voliyumu ya 1100KVar, yomwe imagawidwa m'magulu a 10 amalipiro osinthira okha kuti athe kubweza mafunde apansi pa thiransifoma.45KVAR imasintha pang'onopang'ono voliyumu kuti ikwaniritse zofunikira zamphamvu za mzere wopanga.The 630KVA thiransifoma DC brushless motor mzere wopangira Mphamvu zonse zimalipidwa kuchokera 0.62 mpaka 0.95.The fyuluta chipukuta misozi chipangizo ayenera anaika ndi buku la 600KVar, ndi basi kusagwirizana otsika mbali mapiringidzo a thiransifoma, ndi buku lake pang'onopang'ono kusintha 45KVAR, poganizira zofunika voteji ya mzere kupanga.
Kusanthula zotsatira pambuyo kukhazikitsa chipukuta misozi
Mu Epulo 2010, chipangizo cha DC motor filtering reactive power compensation chidayikidwa ndikuyamba kugwira ntchito.Chipangizochi chimangotsata kusintha kwa katundu wa ma motors a DC ndi ma frequency converter, kupondereza ma harmonics mu nthawi yeniyeni, kubwezera mphamvu zogwira ntchito, ndikuwongolera mphamvu yamagetsi.zambiri monga izi:
Chida cholipirira chikagwiritsidwa ntchito, mphamvu yosinthira mphamvu imakhala pafupifupi 0.99 (gawo lokwezeka limakhala pafupifupi 0.6 pomwe chida cholipirira chosefera chimachotsedwa)
Katundu ntchito
Zomwe zimagwiritsidwa ntchito ndi 1250KVA transformer zimachepetsedwa kuchokera ku 1960A mpaka 1210A, dontho la 38%.Zomwe zimagwiritsidwa ntchito ndi 1630KVA transformer zimachepetsedwa kuchokera ku 1050A mpaka 657A, dontho la 37.5%.Pambuyo pa chipukuta misozi, mtengo wochepetsera kutaya mphamvu ndi WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=32×{(0.62×3000)3000}2×0.4≈15.8( kw· h) Muchilinganizo, Pd ndikutayika kwafupipafupi kwa thiransifoma, yomwe ndi 32KW, ndipo kupulumutsa ndalama zamagetsi pachaka ndi 15.8 * 10 * 30 * 10 * 0.7 = 33,000 yuan (kutengera kugwira ntchito maola 20 a tsiku, masiku 10 pamwezi, ndi miyezi 10 pachaka, pa kwh magetsi 0,7 yuan).
mphamvu factor situation
Ufulu wonse wa kampaniyo wakwera kuchoka pa 0.7 kufika pa 0.95, mwezi uliwonse ufulu wazinthu wakhalabe pa 0.96-0.98, ndipo malipiro a mwezi uliwonse ndi 3,000-4,000 yuan.
Kulipiridwa kwamagetsi kwa DC motor motor low-voltage reactive power kumatha kupondereza kugunda kwapano ndikulipiritsa mphamvu zamagetsi, kuthetsa vuto lachiwongolero chamagetsi, kukulitsa mphamvu ya chosinthira, kuchepetsa kutayika kwa chipukuta misozi, kukulitsa zotuluka, ndi kupereka Kampaniyo yatulutsa phindu lalikulu lazachuma, ndipo kasitomala wapeza ndalama za polojekitiyi kwa nthawi yosakwana chaka chimodzi.Chifukwa chake, kampaniyo ndiyokhutitsidwa kwambiri ndi kubwezeredwa kwamphamvu kwamagetsi a brushless DC ndi zosefera za inverter, ndipo iwonetsa makasitomala ena mtsogolo.
