LZW-72.5 Tansfɔɔmaa Kọrọnti Nwụsị

Na'abuwa na Turanci

LZW-72.5 current transformer, tana da kwalba mai sauki da kuma ingantaccen gida, yana amfani da shi a matsayin masu mara kyau don inya magana, zama ciki da kuma in taimaka wajen samun rukuni a cikin gwamnati na karamin abubuwa ta 50Hz ko 60 Hz da kuma tsari na kirkiro 66kV ko 69kV.

Abubuwa Masu Ma'ana

• Ingantaccen Inganci na Tsari Masu Kyakkyawan Gida: LZW-72.5 tana da tsari masu kyakkyawan 72.5kV da kwalbin magance masu kyakkyawa 125kV (yaki mai hankali) / 70kV (zama ciki na baya). Tana daidai da takardun GB/T 4703.2 da IEC 60044-2, an yi tasirin shi don ingantaccen gida na tsari masu uku a cikin wurare masu 110kV da kuma gasar da take. Wannan yana ba da damar da ci gaba da kuma yana haifar da rawa da fuskantar kwalba.

•  Ingantaccen Tsarin Yakin Magance: Abinci tana da sisan tsaro: tana amfani da kwalba mai sauki na silicon rubber da kuma flanges na aluminum alloy, tana da damar da ci gaba 10,000 awa da yakin UV; tana da IP68+ protection, tana iya yi aiki a kan 2 mita a kan ruwan, da kuma tashin da suka fi sani da yakin jikin 30mm/h da kuma yakin hankali da ya kai 20mm; tana tafi 3,000 awa da yakin makarauta, da kwalbin magance 31mm/kV, tana da damar da ci gaba da yakin al'umma a wuraren tsakiyar da kuma yakin da suka fito da kasa.

• Sistema na Zama Ciki na Kwalba Uku: LZW-72.5 tana da zama ciki na 0.2S-class metering winding da kuma 5P30-class protection winding. Zama ciki na metering tana da damar da ci gaba da ratio error ≤±0.2% a kan 1%~120% rated current, tana da damar da ci gaba da zama ciki na energy; zama ciki na protection tana da composite error ≤5% a kan 30 times rated current da kuma fast response 8ms, tana da damar da ci gaba da speed of relay protection devices. Tana da 3 sets of ratio taps (e.g., 600/5A, 800/5A, 1000/5A), tana iya canza mafi so ku a kan switch na gida bayan sanin da ba ake buccaci ba.

• Tsarin Yakin Magance da Communication Technology: Abinci tana da sensors na multi-parameter don temperature (-40℃~+120℃), humidity, da kuma insulation dielectric loss, tana da damar da ci gaba da data na aiki a lokacin. Tana da IEC 61850-9-2 digital protocol da kuma DL/T 645 standard, da kuma 4~20mA analog output interface, tana da damar da ci gaba da smart substation systems ko kuma compatibility with old monitoring equipment. In-depth analysis of historical data through cloud platforms predicts insulation aging trends in advance, providing data support for operation and maintenance decisions and significantly reducing outdoor inspection frequency and costs.
