Series YTJLW10-720 Voltage Transformers
Derating
Series YTJLW10-720 phase sequence, zero sequence voltage uye yazvino transformer imhando ye AC transformer ine tekinoroji yakanangana neiyo yekutanga uye yechipiri fusion michina yeState Grid uye zvinoenderana neT/CES 018-2018 "Distribution Network 10kV uye 20kV AC Transformers Technical Conditions ". Voltage, ikozvino uye magetsi emagetsi akavakirwa muchigadzirwa, icho chinogona kuunganidzwa zvakananga pamwe nedunhu rinoputika kuita intelligent vacuum circuit breaker.easy kuisa, kushandiswa kwesimba shoma, kunyatsoita uye kuyerwa kwakagadzikana.
■ Iyo huru capacitor inoshandisa yakaenzana capacitance kuunganidza voltage, iyo ine yakanaka kugadzikana kwenguva refu uye yenguva refu yekushanda ruzivo mumagetsi emagetsi.
■ Iyo inobuda yemukati kuramba idiki, iyo inogona kuchinjika kune akasiyana tambo, kukurira kukanganisa kunokonzerwa netambo, uye kukanganisa kwetambo yekuchinjisa isingasviki 0.1%.
■ Shanduko diki yechokwadi yakakanganiswa nekupisa kwemukati, uye iyo yakanyanya kukanganisa shanduko iri pasi pe0.5% mukuzara kwekushisa kwe -40 °C ~ 70 °C, iyo inonyatsozadzisa kudiwa kweiyo tembiricha yekuchinja indekisi zvinodiwa zve3-level. transformer inotsanangurwa.
■ inotora simba rakadzikama rekudzivirira uye yakaderera-simba musimboti mhepo, yakanaka kubuda kugadzikana uye kunyatso hunyanzvi, uye inosangana nemamiriro ekushanda emamiriro ese ekushanda.

Kuisa mirayiridzo uye zvidziviriro
■ Iva nechokwadi chekubatana kwakavimbika pakati pewaya yepasi uye imba panguva yekuisa.
■ Yechipiri inobuda siginecha inotungamira yetransformer inofanirwa kuvharirwa padhuze nebhokisi, uye iyo yakawandisa inotungamira inofanirwa kudimburirwa.
■ Yechipiri voltage inobuda ye transformer kusvika pasi inorambidzwa kushanda frequency inomira voltage
■Mirairo yewaya yechipiri
