Zambiri za ogwiritsa ntchito
A welded mauna fakitale makamaka imapanga zosiyanasiyana welded mauna mapepala, maukonde mipanda, maukonde udzu, maukonde gabion, mbedza maukonde, ukonde barbecue, akalulu khola, ndi zina zotero. Zida kupanga mzere kampani yaikulu, sing'anga ndi ang'onoang'ono kuwotcherera makina, ndi thiransifoma kugawa ndi 1000 kVA ndi 1630 kVA thiransifoma.Chithunzi cha dongosolo lamagetsi ndi motere:
Zomwe zimagwira ntchito
Mphamvu yonse yamakina owotcherera okhala ndi thiransifoma ya 1000KVA ndi 1860KVA, mphamvu yapakati ndi PF = 0.7, ndipo kusinthasintha kogwira ntchito ndi 1050-2700A.Mphamvu yonse yamakina owotcherera ndi 630KVA thiransifoma ndi 930KVA, mphamvu yapakati ndi PF = 0.7, komanso kusinthasintha kogwira ntchito Panopa ndi 570-1420A.
Kusanthula Mkhalidwe Wamagetsi
Makina opangira kuwotcherera magetsi amagwiritsidwa ntchito kwambiri potsitsa katundu wamkulu wapano, womwe ndi katundu wopanda mzere.Zida zimapanga ma harmonics ambiri panthawi yogwira ntchito.Ma harmonic apano amtundu wamtundu wa harmonic amalowetsedwa mu gridi yamagetsi, ndipo grid impedance imapanga voteji ya harmonic, kuchititsa kuti magetsi a gridi ndi Kusokonezeka kwamakono kumakhudza khalidwe lamagetsi ndi chitetezo cha ntchito, kumawonjezera kutayika kwa mzere ndi kuchepetsa mphamvu, ndikuwonjezera mphamvu.Chifukwa chake, ndikofunikira kusankha pulogalamu yamakina yokhala ndi vuto la harmonic kuti ipondereze ma harmonics, kubweza katundu wokhazikika, ndikuwongolera mphamvu.
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
Kutengera momwe zinthu ziliri pakampaniyo, kampaniyo imaganizira mozama za mphamvu yamagetsi komanso kuponderezana kwamphamvu kwa sefa yoyeserera mphamvu yolipirira makina owotcherera, ndikuyika chida cholipirira mphamvu zosefera pa mbali ya 0.4KV yamagetsi otsika abizinesi. thiransifoma kuti ipondereze ma harmonics ndikulipira mphamvu yokhazikika kuti ipititse patsogolo mphamvu yamagetsi.
Panthawi yogwiritsira ntchito makina owotcherera, nthawi 3 za 150HZ, nthawi 5 za 250HZ ndi pamwamba pa ma harmonics amapangidwa.Chifukwa chake, pamapangidwe a chiwongola dzanja champhamvu cha sefa yachiwiri yowotcherera makina, ma frequency a 150HZ, 250HZ ndi kuzungulira akuyenera kupangidwa kuti awonetsetse kuti chiwongola dzanja cha fyuluta chingathe kupondereza kugunda kwapano pomwe kulipiritsa katundu wotakataka ndikuwongolera mphamvu. chinthu.
ntchito yopanga
Mphamvu yokwanira yopangira makina owotcherera achiwiri omwe amafanana ndi thiransifoma ya 1000 kVA amalipidwa kuchokera pa 0,7 mpaka 0,92.Chipangizo chosefera Zida zolipirira ziyenera kuyikidwa ndi mphamvu ya 550 kVA.Magulu 9 a ma capacitor akugawikana kwa gawo amangolumikizidwa ndikuchotsedwa, chilichonse chomwe chimafanana ndi mafunde omwe ali pansi pamagetsi a transformer.Mphamvu yosinthira kalasi ndi 25KVAR, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana zamagetsi zamakina owotcherera a chitsimikizo chachiwiri.Mphamvu yokwanira ya makina owotcherera a chitsimikizo chachiwiri chofanana ndi thiransifoma ya 630 kVA imalipidwa kuchokera pa 0,7 mpaka pafupifupi 0.92.Zida zolipirira zida zosefera ziyenera kukhazikitsidwa ndi mphamvu ya 360 kVA.Magulu 9 a ma capacitor akugawikana kwa gawo amangolumikizidwa ndikuchotsedwa, chilichonse chomwe chimafanana ndi mafunde omwe ali pansi pamagetsi a transformer.Mphamvu yosintha kalasi ndi 25KVAR, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana zamagetsi pamzere wopanga.Mapangidwe awa ndi okwanira kuwonetsetsa kuti mphamvu yosinthidwa ndiyoposa 0.92.
Kusanthula zotsatira pambuyo kukhazikitsa chipukuta misozi
Mu April 2010, fyuluta zotakasuka mphamvu chipukuta misozi chipangizo makina kuwotcherera anatumizidwa kunja fakitale.Chipangizochi chimangotsata kusintha kwa makina owotcherera, kuthamangitsa mphamvu yolipirira ya harmonic munthawi yeniyeni, ndikuwongolera mphamvu yamagetsi.zambiri monga izi:
Chida cholipirira chikagwiritsidwa ntchito, mphamvu yosinthira mphamvu imakhala pafupifupi 0.97 (gawo lokwezedwa limakhala pafupifupi 0.8 pomwe chida cholipirira chosefera chimachotsedwa)
Katundu ntchito
Kugwira ntchito kwa 1000KVA thiransifoma kumatsika kuchokera ku 1250A mpaka 1060A, kutsika kwa 15%, ndipo ntchito yamakono ya 630KVA imatsika kuchokera ku 770A mpaka 620A, kuchepetsa kuchepa kwa 19%.Pambuyo pa chipukuta misozi, mtengo wochepetsera kutaya mphamvu ndi WT=△Pd*(S1/S2)2*τ*[1-(cosφ1/cosφ2)2]=24×{(0.85×2000)/2000}2×0.4≈16 (kw h) Mu chilinganizo, Pd ndi kutayika kwafupipafupi kwa thiransifoma, yomwe ndi 24KW, ndipo kupulumutsa pachaka kwa ndalama zamagetsi ndi 16 * 20 * 30 * 10 * 0.7 = 67,000 yuan (kutengera ntchito maola 20 a tsiku, masiku 30 pamwezi, miyezi 10 pachaka, 0,7 yuan pa kWh).
mphamvu factor situation
Mphamvu yayikulu ya bizinesiyo idakwera kuchokera pa 0.8 mpaka 0.95 m'mwezi wapano, ndipo mphamvu ya pamwezi ikhalabe pa 0.96-0.98 mtsogolomo, ndipo bonasi ya pamwezi idzakhala 3000-5000 yuan.
Pomaliza
Chipangizo chamagetsi chowongolera magetsi chimatha kupondereza ma harmonics ndikubwezera mphamvu zokhazikika, kuthetsa vuto la chiwongola dzanja champhamvu m'mabizinesi, kukulitsa mphamvu yotulutsa ma transformer, kuchepetsa kutayika kowonjezera, kukulitsa kupanga, ndikubweretsa chuma chambiri. zopindulitsa kwa mabizinesi.Bweretsani ndalama zosakwana chaka.Chifukwa chake, chida cholipirira mphamvu chokhazikika chopangidwa ndi kampaniyo ndichokhutiritsa kwambiri, ndipo chidzakopa makasitomala ambiri m'tsogolomu.
