GCK low-voltage withdrawable switchgear chimagwiritsidwa ntchito mu zomera mphamvu, zitsulo anagubuduza, petrochemical, makampani kuwala ndi nsalu, madoko, nyumba, mahotela ndi malo ena monga AC atatu gawo anayi kapena asanu dongosolo waya, voteji 380V, 660V, pafupipafupi 50Hz, oveteredwa Amagwiritsidwa ntchito pogawa mphamvu ndi kuwongolera kwapakati pamakina opangira magetsi okhala ndi mafunde a 5000A ndi pansi.
GCK ndi switchgear yotsika kwambiri yolumikizidwa ndikusonkhanitsidwa, ndipo idapangidwa kuti ikwaniritse izi:
National standard GB7251.1-2005 "Low-voltage switchgear"
Muyezo wapadziko lonse wa IEC60439.1-1992 "Low-voltage switchgear and control zida"
Tanthauzo la Chitsanzo
Malo Ogwiritsiridwa Ntchito Mwachizolowezi
◆ Kutentha kwa mpweya wozungulira sipamwamba kuposa +40 ℃, osati kutsika kuposa -5 ℃, ndipo pafupifupi kutentha mkati mwa maola 24 sipamwamba kuposa +35 ℃;
◆ Kutentha kwachibale sikudutsa 50% pa kutentha kwakukulu + 40 ℃, ndipo kutentha kwapamwamba kumaloledwa pa kutentha kochepa, monga 90% pa +20 ℃;
◆ Mpweya wabwino, wopanda mpweya wowononga komanso wophulika, wopanda fumbi loyendetsa komanso lotsekereza:
◆ Ngati palibe kugwedezeka kwakukulu ndi kugwedezeka kwamphamvu, kuyika koyima, kupendekera sikuyenera kukhala kwakukulu kuposa madigiri a 5;
◆ Kutalika sikudutsa mamita 2000;
◆ switchgear ndi yoyenera kunyamula ndi kusungirako kutentha: -25 ° C mpaka + 55 ° C, osapitirira + 70 ° C panthawi yochepa (osapitirira maola 24);
◆ Ogwiritsa ntchito ayenera kukambirana ndi wopanga ngati zomwe zili pamwambazi sizingakwaniritsidwe.
