Txheej txheem cej luam

ZW8-12 sab nraum zoov high-voltage nqus Circuit Court breaker, peb-theem AC 50Hz sab nraum zoov high-voltage switchgear.Nws yog tsim los ntawm kev ua haujlwm, hluav taws xob hluav taws xob, hluav taws xob hluav taws xob, lub foob thiab lub plhaub, thiab tag nrho cov qauv yog peb-theem hom thawv hom.Nws yog siv rau 10kV nyob deb nroog daim phiaj hluav taws xob thiab hauv nroog lub zog hluav taws xob hluav taws xob, raws li kev sib cais, kev sib koom ua ke tam sim no, dhau tam sim no, luv luv tam sim no thiab lwm qhov chaw zoo sib xws.
Ua raws li tus qauv GB1984-2003 "High Voltage AC Circuit Breaker" GB / T11022-1999 "Cov Kev Xav Tau Rau Cov Hluav Taws Xob Hluav Taws Xob thiab Cov Khoom Siv Tswj" IEC62271-100 "High Voltage AC Circuit Breaker"

Cov xwm txheej siv li qub

◆ Ambient kub: -40 ℃ ~ + 40 ℃;
◆ Qhov siab: ≤3000m (yog tias qhov siab nce, qhov ntsuas hluav taws xob yuav nce raws li);
◆ Cov huab cua ib puag ncig tuaj yeem ua paug los ntawm plua plav, pa taws, roj corrosive, chav lossis ntsev tsuag, thiab cov pa phem yog IV;
◆ Cua ceev tsis tshaj 34m / s (sib npaug rau 700Pa ntawm qhov chaw cylindrical);
◆ Kev vibration lossis hauv av txav los ntawm sab nraud ntawm lub tshuab hluav taws xob thiab cov cuab yeej tswj tau raug tsis quav ntsej;
◆ Cov xwm txheej tshwj xeeb ntawm kev siv.(Yog tias koj xav siv nws raws li kev siv ib txwm siv sib txawv ntawm cov saum toj no, thov nrog peb tham).
