Matoorka danab-sare leh
Guud ahaan waxaa la aaminsan yahay in matoorka leh danab sahay ah oo ah 3KV ~ 10KV loo yaqaan amatoorka danab sare lehMatoorada 6300V iyo 10000V ayaa si caadi ah loo isticmaalaa. Awoodda matoorku waxay la mid tahay wax soo saarka danabka iyo hadda, sidaa darteed awoodda matoorka danabka hooseeya waxay kor u kacdaa ilaa xad gaar ah (sida 300KW/380V), hadda la qiimeeyay aad bay u weynaan doontaa, khasaaraha khadka waxaa la mid noqon doonaa kororka hadda (I^2*r), aagga isgoyska ee fiilada waxaa looga baahan yahay inuu aad u weynaado, sidaa darteed awoodda qaadida ee la oggol yahay ee fiilada waa xaddidan tahay, kharashkuna aad buu u sarreeyaa. Waqtigan xaadirka ah, waxaa lagama maarmaan ah in la kordhiyo danabka hawlgalka ee la qiimeeyay si loo gaaro wax soo saar koronto oo sare.
Matoorka danab hooseeya
Matoorka danab hooseeya waxaa loola jeedaa danabka AC ee ka hooseeya matoorka 1000V, guud ahaan waxaa loola jeedaa matoorka AC 380V, 440V ama 660V iyo heerarka kale eematoorada aan isku mid ahayndhab ahaantii waxaa loo isticmaalaa si ka yar. Matoorka danab hooseeya waxaa loo qaybiyaa laba nooc oo matoorka AC aan isku mid ahayn iyo matoorka DC.
Faa'iidooyinka iyo khasaarooyinka matoorrada danab-sare leh marka la barbar dhigo matoorrada danab-hooseeya
(1) Faa'iidooyinka
(1) waxaa loo samayn karaa awood weyn, ilaa kumanaan ama xitaa tobanaan kun oo kiilowatts. Tani waa sababta oo ah, isla awoodda wax soo saarka, hadda matoorka danab-sare wuxuu aad uga yar yahay matoorka danab-sare (asal ahaan si liddi ku ah danab-ka), tusaale ahaan, 500kW, hadda matoorka 4-cirif leh ee lagu qiimeeyay, danab-qiimeyn ah oo ah 380V 900A ama wax la mid ah, halka danab-qiimeyn ah oo ah 10kV oo keliya 30A ama wax la mid ah. Markaa wareegga matoorka danab-sare leh wuxuu noqon karaa dhexroor silig yar. Natiijo ahaan, luminta naxaasta stator-ka ee matoorka danab-sare leh waxay sidoo kale ka yaraan doontaa tan matoorka danab-sare leh. Matoorada korontada ee waaweyn, isticmaalka korontada danab-sare leh, laakiin sababtoo ah baahida loo qabo fiilooyin qaro weyn oo u baahan aag weyn oo godka stator-ka ah, si dhexroorka xudunta stator-ku uu u qabto shaqo badan, cabbirka oo dhan ee matoorka ayaa sidoo kale aad u weyn.
② Matoorada awoodda weyn leh, matoorada danab sare leh ee loo isticmaalo qalabka korontada iyo qaybinta marka loo eego maalgashiga guud ee matoorada danab hooseeya, khasaaraha khadkana waa yar yahay, waxay badbaadin kartaa xaddi gaar ah oo isticmaalka korontada ah. Gaar ahaan, matoorada danab sare leh ee 10kV, waxaad si toos ah u isticmaali kartaa korontada shabakadda (korontada danab sare leh ee Shiinaha ee la siiyo isticmaalayaasha guud ahaan waa 10kV), si maalgashiga qalabka korontada (badanaa transformers) uu u yaraado, isticmaalka fudud, heerka cilladuna wuu yaraan doonaa.
(2) Khasaaraha
① Qiimaha duubista waa mid aad u sarreeya (badanaa waxaa sababa dahaarka), qiimaha agabka dahaarka ee la xiriira ayaa sidoo kale ka sarreeya.
(ii) Habka daaweynta dahaarka ayaa aad u adag, kharashka shaqaduna waa ka sarreeyaa.
③ Shuruudaha isticmaalka deegaanka ayaa aad uga adag kuwa matoorrada danab-yar.
Isbarbardhigga farqiga u dhexeeya matoorka danab hooseeya iyo matoorka danab sare leh
Farqiga ugu weyn ee qaab-dhismeedka
Marka hore, walxaha dahaarka gariiradda waxay sameeyaan farqi, matoorrada danab hooseeya, gariiradda inta badan silig lagu dahaadhay ama dahaar kale oo fudud, sida warqad isku dhafan, dahaarka matoorka danab sare leh waxaa badanaa loo isticmaalaa qaab-dhismeedka lakabka badan, sida cajaladda mica budada ah, qaab-dhismeedku waa mid aad u adag, heer sare oo iska caabin cadaadis ah.
Marka labaad, farqiga u dhexeeya qaab-dhismeedka qaboojinta, matoorada danab-yar waxay inta badan isticmaalaan marawaxadaha coaxial-ka ee si toos ah u afuufaya kulaylka, matoorada danab-yar ee leh inta badan radiator-ka madax-bannaan, badanaa laba nooc oo marawaxadaha ah, set oo marawaxadaha wareegga gudaha ah, set oo marawaxadaha wareegga dibadda ah, laba nooc oo marawaxadaha ah oo isku mar wada, is-weydaarsiga kulaylka radiator-ka waxaa laga saari doonaa meel ka baxsan kulaylka matoorka.
Saddexaad, qaab-dhismeedka booyadaha waa ka duwan yahay, matoorada danab-yar waxay badanaa leeyihiin booyadaha ka hor iyo ka dib, halka matoorada danab-yaraha sare, sababtoo ah culayska culus, badanaa waxaa jira laba booyadaha ku yaal dhammaadka booyadaha, tirada booyadaha ku yaal dhammaadka aan booyadaha lahaynna waxaa lagu go'aamiyaa xaaladda culayska, gaar ahaan matoorada waaweynna waxay isticmaali doonaan booyadaha simbiriirixan.
Isbarbardhigga hawlgalka mootada iyo kharashka
1. Heerka danabku wuu sarreeyaa, awoodda matoorku way sii weynaanaysaa.
2, heerka danabku kor u kaco, qiimaha rakibidda oo kordha; inkastoo danabku kor u kaco hadda wuu yaraadaa, siligga iyo fiilada isgoysyada ayaa la dooran karaa kuwo yar, laakiin baahida loo qabo jebinta wareegga danab-sare, transformers-ka, qalabka wax lagu beddelo iyo kharashyada kale ee qalabka ayaa weli kordhay maalgashiga bilowga ah ee waaweyn, sidaa darteed ganacsiyada yaryar ee dhismaha cusub waxay diyaar u yihiin inay isticmaalaan qalabka danab-hooseeya.
3, heerka danabku kor u kaco, kharashka hawlgalka oo yaraada; koronto yar oo keenta hoos u dhac ku yimaada khasaaraha korontada, mustaqbalka fog waa ku habboon tahay, saameynta isku-darka ee keydinta korontada waa mid cajiib ah, shirkado badan oo waaweyn ayaa isbeddel ku sameeyay tignoolajiyada matoorada danab hooseeya oo isu beddelay matoorada danab sare leh.
4, heerka danabku kor u kaco, booska badan ayaa la geli karaa; sababtoo ah waxaa jira armaajooyin kontarool oo danab sare leh iyo dadka kale ee ku jira.
5, heerka danabku sareeyo, matoorku si fudud ayuu u bilaaban karaa, kor u kaca awoodda, bilaabista, xakamaynta waa mid fudud.
6, heerka danabku sareeyo, maaraynta dayactirka oo aad u adag; sidaa darteed ganacsiyada yaryar waxay diyaar u yihiin inay isticmaalaan danab hooseeya, shirkadaha waaweynna waxay diyaar u yihiin inay isticmaalaan matoorada danab sare leh.
