Kuona Kugona Kutakura Kwepamusoro-soro KW kweTransformer ye1000kVA

Maitiro Ekuverenga Kuyera Kwemutoro weKW we1000kVA Transformer Zvichibva Pasimba

 

 

Netransformer yekare ye1000kVA iri kubata mutoro weinenge 200kW, transformer iyi inogona here kugamuchira kudiwa kuri kuwedzera kana tichironga kuwedzera mutoro mutsva weinenge 600kW? Mubvunzo uyu unonyanya kutenderera papfungwa huru: hukama nemusiyano uripo pakati pekVA nekW.

 

 

Hukama uye musiyano uripo pakati pe kVA ne kW

 

 

kVA (kilovolt-ampere) iyuniti yesimba rinoonekwa, nepo kW (kilowatt) ichimiririra yuniti yesimba rinoonekwa. Kuwedzera kune simba rinoonekwa uye simba rinoonekwa, kunewo simba rinoonekwa, rinoyerwa mu kvar (kilovar).

 

 

 

Ndeipi musiyano uripo pakati pesimba rinoita basa, simba rinoita basa, uye simba rinoonekwa?

 

 

Simba Rinoshanda: Richiyerwa mu watts (W), rinomiririra simba chairo rinoshandiswa kana basa rinobatsira rinoitwa nedunhu (semuenzaniso, kupisa, mwenje).

 

 

 

Simba Rinopindura: Richiyerwa mu volt-amperes reactive (VAR), rinotsigira masimba emagineti muzvinhu zvinopa simba (semuenzaniso, mamota) asi harishande. Semuenzaniso, kana mudziyo wemagetsi uine ma capacitor kana ma coil, zvikamu izvi zvinoramba zvichichaja uye zvichiburitsa simba mudziyo uchishanda. Sezvo ma capacitor/ma coil asingashandisi simba remagetsi panguva yekuchaja/kuburitsa simba, simba rinobatanidzwa rinonzi ‌reactive power‌.

 

 

 

Simba Rinoonekwa: Richiyerwa mu volt-amperes (VA), imusanganiswa wesimba rinoita basa nerinoita basa, zvichimiririra simba rese riri mudunhu. Sosi yemagetsi (kazhinji transformer kana jenareta) haifanire kungopa simba rinoita basa chete asiwo simba rinoita basa kumidziyo yemagetsi. Izvi zvinodaro nekuti, kunyangwe ma capacitor ari mumudziyo asingashandise simba rinoita basa, kuchaja nekuburitsa simba nguva dzose zvichiri kuda kuti sosi yemagetsi igovere chikamu chekugona kwayo kutsigira maitiro aya.

 

 

 

Mushure mekujekesa pfungwa idzi, tinogona kuongorora hukama hwadzo, izvo zvinotitungamira kune imwe pfungwa yakakosha: ‌power factor‌. Huwandu hwesimba rinoitwa nemagetsi hunoenderana zvakananga nepower factor.

 

 

 

Kana mutengo wemagetsi uri pa$1 pa kilowatt-awa (kWh), transformer inoshanda nesimba re0.6 inogona kuburitsa mari inosvika $600/awa. Kana simba remagetsi ravandudzika kusvika pa0.9, transformer imwe chete inogona kuburitsa mari inosvika ¥900/awa. Kunyange hazvo mabhenefiti emari ekuvandudza simba remagetsi ari pachena, zvayakanakira pahunyanzvi hwayo (semuenzaniso, kugadzirisa kugadzikana kwegrid uye kuderedza kurasikirwa nesimba) zvinopfuura izvi zvinokurumidza.

 

 

 

Transformer ye1000kVA inogona kutsigira makilowatts mangani (kW)?

 

 

 

 

Neruzivo rwekutanga rwakasimbiswa pamusoro apa, ikozvino tinogona kugadzirisa mubvunzo mukuru wechinyorwa chino nekujeka uye nemazvo.

 

 

 

Kugona kwetransformer kunoyerwa mu ‌kVA (kilovolt-amperes), ukuwo simba rinoshandiswa nemidziyo yemagetsi richiyerwa mu ‌kW (kilowatts). Musiyano mukuru uri pakuti kuverenga simba rinoshanda (kW) remudziyo kunoda kuwedzera simba rayo rinoratidza simba (kVA) ne ‌power factor (cosφ). Semuenzaniso, transformer ye1000kVA inogona chete kupa simba rakazara re ‌1000kW kana ichishanda pa power factor ye ‌1.0‌. Zvisinei, kuwana mamiriro aya akanaka (PF = 1.0) hazvigoneke mumashandisirwo chaiwo.

 

 

 

 

 

 

 

Muchikamu chekugadzira, kana tikashandisa simba rekugadzirisa kuti tiwane simba re 0.95, simba rinobuda mu transformer rinofanira kuverengwa se 1000×0.95=950kW. Chiziviso Chakakosha: Power utilities inorayira simba remagetsi (PF) re ‌≥0.9‌ kudzivirira zvirango; zvisinei, kudarika ‌PF = 1.0‌ kunogona kukonzera kukwira kwemagetsi esystem uye kukanganisa kugadzikana kwegrid‌.

 

 

 

Transformer ye1000kVA inotanga ichipa magetsi e200kW. Mushure mekuwedzera simba idzva re600kW, simba rese rinodiwa rinosvika ‌800kW, iro rinoramba riri mukati memuganhu wekuchengetedza wakaverengerwa wetransformer.

 

 

 

Saka, transformer ye1000kVA iyo pakutanga yaitengesa 200kW yemagetsi inogona kushanda zvakachengeteka kwenguva refu kunyangwe mushure mekuwedzera 600kW itsva (800kW yese), chero bedzi simba rayo rakagadziridzwa kusvika padanho rinodiwa.
