Chotsukira Choteteza Magalimoto Chopangidwa ku China CJRV-32H 32A Choyambira Chithunzi Chodziwika

Chopangidwa ku China CJRV-32H 32A Motor Starter Motor Protection Circuit Breaker

Kufotokozera Kwachidule:

Chotsekera ma circuit cha CJRV series AC Motor protection circuit breaker ndi choyenera ma circuit okhala ndi AC voltage mpaka 690V ndi current power mpaka 80A. lt imagwiritsidwa ntchito powonjezera mphamvu, kulephera kwa phase, kuteteza short circuit, komanso kuwongolera kosalekeza kwa ma motors a asynchronous cage a squirrel a phase atatu. Ingagwiritsidwe ntchito poteteza mzere wogawa ndi kusinthana kwa katundu pafupipafupi, komanso ingagwiritsidwe ntchito ngati chodzipatula.

Zinthu zachizolowezi zogwirira ntchito ndi kukhazikitsa

Kutalika kwa malo oikirako nthawi zambiri sikupitirira 2000m;
Malire otsika a kutentha kwa mpweya wozungulira nthawi zambiri sali otsika kuposa -5 ℃, malire apamwamba nthawi zambiri sali okwera kuposa +40 ℃, ndipo mtengo wake wapakati mkati mwa maola 24 supitirira +35 ℃;
Chinyezi cha mpweya sichiyenera kupitirira 90% (pa +25 ℃ ± 5 ℃)
Kuchuluka kwa kuipitsidwa kwa chilengedwe chozungulira ndi mlingo wachitatu wa kuipitsidwa;
Gulu lokhazikitsa la choyambira ndi gulu lokhazikitsa lll;
Kupendekeka pakati pa choyambira ndi malo oyimikapo sikuyenera kupitirira ± 5 °;
Mlingo wogwa: CJRV-25 (X),CJRV-32 (X),CJRV-32H,CJRV-80:10A;
Maola ogwira ntchito owerengedwa: maola ogwira ntchito osasinthasintha, maola ogwira ntchito a maola asanu ndi atatu.
