Kusintha kabati ndi mtundu wa zida zamagetsi.Mizere yakunja ya kabati yosinthira imalowetsa chosinthira chachikulu mu nduna yoyamba, kenako ndikulowetsani sub control switch.Nthambi iliyonse imayikidwa molingana ndi zosowa zake.Mwachitsanzo, zida, zowongolera zokha, masiwichi amotor maginito, zolumikizira zosiyanasiyana za AC, ndi zina zambiri. Zina zilinso ndi chipinda chamagetsi chamagetsi komanso makabati otsika otsika kwambiri, mabasi othamanga kwambiri, monga magetsi opangira magetsi, etc., ndi zina. alinso okonzeka ndi otsika mkombero katundu kukhetsa zipangizo zazikulu.
The lophimba nduna ali ndi ntchito za mizere pamwamba obwera ndi otuluka, chingwe mizere ukubwera ndi wotuluka, kugwirizana basi, etc. Iwo makamaka ntchito ku malo osiyanasiyana monga magetsi zomera, substations, petrochemical, metallurgical zitsulo anagubuduza, makampani kuwala ndi nsalu, mafakitale. ndi mabizinesi amigodi, nyumba zogona, nyumba zazitali, etc.
2. Mtundu wazinthu
Chosinthiracho chidzakwaniritsa zofunikira za "Standard for AC Metal Enclosed Switchgear", yomwe ili ndi zigawo ziwiri zazikulu: thupi la nduna ndi wophwanya dera.Thupi la nduna limapangidwa ndi chipolopolo, zida zamagetsi (kuphatikiza magawo oteteza), makina osiyanasiyana, ma terminals achiwiri ndi waya.
KYN series medium voltage switchgear ndi m'badwo watsopano wa switchgear wopangidwa ndi JONCHN Gulu molingana ndi momwe dziko la China likukhalira pamaziko a kukhazikitsidwa kwaukadaulo wapamwamba kuchokera ku Areva.
