Zambiri za ogwiritsa ntchito
Kampani yoponya ma valve pachipata makamaka imapanga zinthu za valve.Zida zopangira zida za kampaniyi zikuphatikiza ng'anjo yoyatsira tani imodzi, yomwe imagwiritsa ntchito 2000 kVA (10KV/0.75 kVA) yaukadaulo wamagetsi osinthira magetsi, ndipo imakhala ndi makabati awiri olipira ma capacitor okhala ndi voliyumu ya 600 kVA, a ng'anjo yoyatsira tani imodzi yapakatikati, 800 kVA (10KV/0.4 kVA) katswiri wopangira magetsi osinthira magetsi, kabati yamalipiro ya capacitor yokhala ndi mphamvu ya 300 kVA.Chithunzi cha dongosolo lamagetsi ndi motere:
Mphamvu yowoneka ya ng'anjo yapakatikati yokhala ndi chosinthira cha 2000KVA ndi 700KVA-2100KVA, mphamvu yogwira ndi P=280KW-1930KW, katundu wokhazikika ndi Q=687KAR-830KAR, chinthu champhamvu ndi PF=0.4-0.92, ndi yomwe ikugwira ntchitoⅰ = 538 A-1660 A, mphamvu yowonekera ya ng'anjo yapakatikati yokhala ndi thiransifoma ya 800KVA ndi 200KVA-836KVA.Mphamvu yogwira ndi P=60KW-750KW, katundu wokhazikika ndi Q=190KAR-360KAR, mphamvu ndi PF=0.3-0.9, ndi panopa i=288 A-1200 A. Chifukwa capacitor compensation cabinet sangathe kuikidwa kugwira ntchito (malipiro amoto amalephera, pamene capacitor ikugwiritsidwa ntchito pamanja, phokoso la capacitor ndilosazolowereka, maulendo oyendetsa dera, capacitor amapakidwa, mafuta atayikira, osweka, ndipo sangathe kugwiritsidwa ntchito), mphamvu ya mwezi uliwonse. PF=0.78, ndipo chiwongola dzanja cha pamwezi chimasinthidwa kupitilira 32,000 yuan.
Kusanthula Mkhalidwe Wamagetsi
Katundu wofunikira wamagetsi okonzedwanso a ng'anjo yapakatikati ndi ma pulse ballast asanu ndi limodzi.Zida zokonzanso zimapanga ma harmonics ambiri zikasintha AC panopa kukhala DC, yomwe ndi gwero la ma harmonics.Mphamvu yamagetsi yomwe imalowa mu gridi yamagetsi imayambitsa mphamvu yamagetsi yogwiritsira ntchito mphamvu yamagetsi pamtundu wa gridi yamagetsi, zomwe zimapangitsa kutayika kwa magetsi ogwirira ntchito komanso panopa pa gridi yamagetsi, kuyika pangozi khalidwe ndi chitetezo cha kayendedwe ka magetsi, kuwonjezeka. kutayika kwa ma chingwe ndi kupatuka kwa magetsi ogwirira ntchito, ndikupangitsa kuwonongeka kwa gridi yamagetsi ndi kukonza Zida zamagetsi za fakitale zidzabweretsa zoopsa.Pamene zotakasuka mphamvu chipukuta misozi capacitor banki ndi kuika mu ntchito, chifukwa harmonic khalidwe Impedans wa capacitor banki ndi yaing'ono, chiwerengero chachikulu cha harmonics anadzetsa mu banki capacitor, ndi capacitance panopa ukuwonjezeka mofulumira, kukhudza kwambiri moyo wake utumiki.Komano, pamene harmonic capacitive zimachitikira banki capacitor ndi wofanana harmonic inductive zimachitikira dongosolo ndi mndandanda resonance zimachitika, harmonic panopa kwambiri anakulitsa (2-10 nthawi), chifukwa kutenthedwa ndi kuwonongeka kwa capacitor.Kuphatikiza apo, ma harmonics amapangitsa kuti mafunde a sinusoidal a DC asinthe, zomwe zimapangitsa kuti pakhale nsonga yamtundu wa sawtooth, zomwe zimakhala zosavuta kutulutsa pang'ono muzinthu zoteteza.Kutulutsa kwapang'onopang'ono kwa nthawi yayitali kumathandiziranso kukalamba kwa zinthu zoziziritsa kukhosi ndikupangitsa kuwonongeka kwa capacitor mosavuta.Chifukwa chake, capacitor reactive power compensation cabinet siyingagwiritsidwe ntchito polipira ng'anjo yapakatikati ya ng'anjo yapakatikati, ndipo chida cholipirira mphamvu chogwiritsa ntchito fyuluta chokhala ndi pulse current kupondereza chiyenera kusankhidwa.
Dongosolo la chithandizo chamalipiro amphamvu
Zolinga zaulamuliro
Zida zolipirira zosefera zidapangidwa kuti zikwaniritse zofunikira pakuwongolera ma harmonics ndi mphamvu yogwira ntchito.
Mumayendedwe a 0.75KV ndi 0.4KV, zida zolipirira zosefera zitachoka mufakitale, ma harmonics apamwamba amaponderezedwa pamwezi ndi mphamvu ya 0.95 kapena kupitilira apo.
Kulowetsa kwa lupu yamalipiro a fyuluta sikungapangitse kugunda kwapakatikati kapena kuchulukira kwamphamvu komanso kupitilira apo.

Malingaliro opangira
Malinga ndi momwe kampaniyo ilili, kampani yathu yapanga mndandanda watsatanetsatane wanthawi yayitali wa ng'anjo yamagetsi yogwiritsira ntchito mphamvu zolipirira zosefera.Ganizirani mozama za katundu wamagetsi ndi kuponderezedwa kwa harmonic, ndikuyika zosefera zolipirira mphamvu zotsika-voltage pansi pa voltage ya 0.75KV ndi 0.4KV thiransifoma ya kampaniyo kuti ipondereze ma harmonics, kubwezera mphamvu zotakataka, ndikuwongolera mphamvu yamagetsi.Pakugwira ntchito kwa ng'anjo yapakati pafupipafupi, chipangizo chowongolera chimapanga ma 6K + 1 ma harmonics, ndipo mndandanda wa Fourier umagwiritsidwa ntchito kuwola ndikusintha zomwe zilipo kuti apange ma harmonics 5 a 250HZ ndi ma harmonics 7 pamwamba pa 350HZ.Chifukwa chake, pamapangidwe apakati pafupipafupi induction ng'anjo fyuluta reactive mphamvu chipukuta misozi, pafupipafupi 250HZ, 350HZ ndi mozungulira ayenera kupangidwa kuonetsetsa kuti fyuluta chipukuta misozi akhoza kupondereza pulse panopa pamene kubweza katundu wotakataka ndi kukonza mphamvu chinthu.
ntchito yopanga
Mphamvu yokwanira ya ng'anjo yapakatikati ya 2-ton yofanana ndi thiransifoma ya 2000 kVA imalipidwa kuchokera pa 0.78 mpaka 0.95.Chipangizo cholipirira zosefera chiyenera kukhala ndi mphamvu ya 820 kVA, ndipo chimasinthidwa kukhala magulu 6 a mphamvu, iliyonse yomwe imagwirizana ndi mapiritsi omwe ali pansi pamagetsi a thiransifoma kuti alipire.Mphamvu yosinthira magulu a kalasi ndi 60KVAR, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana za ng'anjo yapakati pafupipafupi.Mphamvu yokwanira ya ng'anjo yapakatikati ya tani imodzi yofananira ndi thiransifoma ya 800 kVA imalipidwa kuchokera pa 0.78 mpaka pafupifupi 0.95.Zida zolipirira zosefera ziyenera kukhala ndi mphamvu ya 360 kVA, yomwe imatha kusinthidwa kukhala magulu 6 amphamvu, ndipo mphamvu yosinthira yosinthidwa ndi 50 kVA, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana zamagetsi pang'anjo yapakati pafupipafupi.Mapangidwe amtunduwu amatsimikizira kwathunthu kuti mphamvu yosinthidwa ndiyokwera kuposa 0.95.
Kusanthula zotsatira pambuyo kukhazikitsa chipukuta misozi
Kumayambiriro kwa June 2010, chipangizo chapakati cholipirira ng'anjo yapakatikati cha ng'anjo yamagetsi chinayikidwa ndikuyamba kugwira ntchito.Zipangizozi zimangotsatira kusintha kwa katundu wa ng'anjo yapakatikati, makamaka kubwezera katundu wothamanga, ndikuwongolera mphamvu yamagetsi.zambiri monga izi:
Chida cholipirira chikayatsidwa, njira yosinthira mphamvu yamagetsi imakhala pafupifupi 0.97 (chinthu champhamvu pomwe chipangizo cholipirira chosefera chimadulidwa ndi pafupifupi 0.8)

Pakalipano wa 2000KVA transformer yachepetsedwa kuchokera ku 1530A mpaka 1210A, kuchepa kwa 21%;thiransifoma ya 800KVA yafupika kuchokera ku 1140A mpaka 920A, kuchepa kwa 19.3%, komwe kuli kofanana ndi kuchepetsa 20% ya thiransifoma, ndiko kuti, 560KVA, ndi kuwonongeka kwa mphamvu pambuyo pa chipukuta misozi ndi 21%.;Kuwonongeka kwa Transformer kuchepetsedwa ndi WT=?Pd1S2) 2**[1-(1-1/cos2)2]=24{(0.78?2800)/280}20.415(kwh).Kutayika kwa thiransifoma ndi 24 yuan, ndipo kutayika kwa mwezi ndi 15KW = 150d;mtengo wopulumutsa pamwezi ndi 1580d=230d*30d(2307){0.782800}20d.
mphamvu factor situation
Mwezi uno, mphamvu zonse za kampaniyo zidakwera kuchoka pa 0.78 kufika pa 0.97, ndalama zogwiritsira ntchito mwezi uliwonse ndi ndalama zothandizira zidasinthidwa kukhala 0, ndipo chilangocho chinasinthidwa kukhala 4,680 yuan.Kuyambira pamenepo, mphamvu ya mwezi uliwonse yakhalabe pa 0.97-0.98, ndipo mphotho ya pamwezi yakhala pakati pa 3,000-5,000 yuan.
Ambiri, mankhwalawa ali ndi luso kwambiri kupondereza zimachitika panopa ndi kubweza mphamvu zotakasika, kuthetsa vuto la nthawi yaitali kampani kubala chiwongola dzanja ndi zilango zofunikira, kusintha linanena bungwe mphamvu ya thiransifoma, ndi kubweretsa zoonekeratu phindu zachuma kwa kampani , Anachira. ndalama za kasitomala pasanathe chaka.Choncho, zotakasika mphamvu chipukuta misozi ya wapakatikati pafupipafupi ng'anjo opangidwa ndi kampani ndi zokhutiritsa, ndipo adzakopa makasitomala ambiri m'tsogolo.
