Series YTJLW10-720 Voltage Transformers
Kunyoza
Series YTJLW10-720 gawo zinayendera, ziro zinayendera voteji ndi thiransifoma panopa ndi mtundu wa AC thiransifoma ndi specifications luso kuti zigwirizane ndi zida pulayimale ndi sekondale maphatikizidwe wa gululi State ndipo malinga T/CES 018-2018 "Distribution Network 10kV ndi 20kV AC Transformers Technical Conditions ". Voltage, zamakono ndi zosintha zamagetsi zimapangidwira mu mankhwala, omwe amatha kusonkhanitsidwa mwachindunji ndi wozungulira dera kuti apange wanzeru vacuum circuit breaker.easy kukhazikitsa, kugwiritsa ntchito mphamvu zochepa, kulondola kwakukulu ndi kuyeza kokhazikika.
■ Capacitor yaikulu imagwiritsa ntchito mphamvu yofanana kuti itenge magetsi, yomwe imakhala ndi kukhazikika kwa nthawi yaitali komanso nthawi yayitali yogwira ntchito mumagulu amagetsi.
■ The linanena bungwe kukana mkati ndi yaing'ono, amene angagwirizane ndi zingwe zosiyanasiyana, kugonjetsa cholakwika chifukwa zingwe, ndi cholumikizira chingwe cholakwa ndi zosakwana 0.1%.
■ kusintha kolondola kwakung'ono komwe kumakhudzidwa ndi kutentha kozungulira, ndipo kusintha kwakukulu kolakwika kumakhala kosakwana 0.5% mu kutentha kwathunthu kwa -40 °C ~ 70 °C, komwe kumakwaniritsa zofunikira za index ya kusintha kwa kutentha kwa 3-level. transformer yatchulidwa.
■ imatenga mphamvu yokhazikika yolimba kwambiri komanso mafunde otsika kwambiri, kukhazikika kwabwino komanso kulondola kwambiri, ndikukwaniritsa momwe magwiridwe antchito onse amagwirira ntchito.

■ Onetsetsani kukhudzana odalirika pakati pa waya pansi ndi nyumba pa unsembe.
■ Zowongolera zachiwiri za chosinthira thiransifoma ziyenera kulumikizidwa kwambiri ndi bokosilo, ndipo zowongolera zochulukirapo ziyenera kufupikitsidwa.
■ Kutulutsa kwamagetsi kwachiwiri kwa thiransifoma pansi kumaletsedwa kugwira ntchito pafupipafupi kupirira voteji
