GGD AC low-voltage switchgear
Zowonetsa Zamalonda
GGD AC low-voltage switchgear ndi yoyenera machitidwe ogawa mphamvu ndi AC 50Hz, oveteredwa ntchito voteji ya 380V, ndi oveteredwa ntchito panopa mpaka 3150A mu zomera mphamvu, substations, mafakitale ndi mabizinesi migodi, ndi cholinga cha kutembenuka mphamvu, kugawa, ndi kulamulira mphamvu, kuyatsa ndi kugawa zipangizo.
GGD AC low-voltage switchgear ndi mtundu watsopano wa AC low-voltage switchgear wopangidwa molingana ndi zofunikira za akuluakulu a dipatimenti ya Mphamvu, ogwiritsa ntchito mphamvu zazikulu ndi madipatimenti a kamangidwe, potengera mfundo zachitetezo, zachuma, zomveka komanso zodalirika.Chogulitsacho chimakhala ndi mphamvu yosweka kwambiri, kukhazikika kwamphamvu komanso kutentha, njira zamagetsi zosinthika, kuphatikiza kosavuta, kuchitapo kanthu mwamphamvu, kapangidwe katsopano, komanso chitetezo, ndipo chitha kugwiritsidwa ntchito ngati chinthu chosinthidwa pamaseti athunthu amagetsi otsika.
GGD AC low-voltage switchgear imakumananso ndi miyezo monga IEC439 "Complete Low-voltage Switchgear and Controlgear" ndi GB7251 "Low-voltage Complete Switchgear."
Kagwiritsidwe ntchito
Kutentha kwa mpweya wozungulira sikuyenera kupitirira +40 ℃ ndipo kusakhale kutsika kuposa -5 ℃, ndi kutentha kwapakati mkati mwa maola 24 sayenera kupitirira +35 ℃;
Kuyika m'nyumba kumalimbikitsidwa, ndipo kutalika kwa malo ogwiritsira ntchito sayenera kupitirira 2000m, zomwe ziyenera kufotokozedwa poyitanitsa;
Chinyezi chachibale cha mpweya wozungulira sayenera kupitirira 50% pa kutentha kwakukulu kwa +40 ℃, ndi chinyezi chapamwamba (mwachitsanzo 90% pa +20 ℃) amaloledwa pa kutentha kochepa kuti aganizire zomwe zingatheke chifukwa cha condensation chifukwa cha kusintha. mu kutentha;
Mukayika, kupendekera kuchokera pamtunda sikuyenera kupitirira 5 °;
Zipangizozi zikhazikike m'malo omwe mulibe kugwedezeka kwakukulu kapena kugwedezeka komanso zomwe sizingayambitse dzimbiri zamagetsi;
Makasitomala amatha kukambirana ndi wopanga kuti akwaniritse zofunikira zenizeni.

Onetsani Zojambula Zowoneka bwino
zochita kupanga oda:
Poyitanitsa, wogwiritsa ntchito ayenera kupereka:
- Chiwonetsero chachikulu chogawa chigawo ndi mawonekedwe ake, voliyumu yogwirira ntchito, yovoteledwa pakalipano, kuyika kwa zida zoteteza, ndi zofunikira zaukadaulo.
- Sonyezani za chingwe chomwe chikubwera ndi chotuluka.
- Chitsanzo, mafotokozedwe, ndi kuchuluka kwa zigawo zikuluzikulu zamagetsi mu kabati yosinthira.
- Ngati milatho ya mabasi kapena mipata yamabasi ikufunika pakati pa makabati osinthira kapena makabati omwe akubwera, zofunikira zenizeni monga utali ndi kutalika kuchokera pansi ziyenera kuwonetsedwa.
- Makabati osinthira akagwiritsidwa ntchito pazachilengedwe zapadera, malangizo atsatanetsatane ayenera kuperekedwa poyitanitsa.
- Mtundu wapamwamba wa kabati yosinthira ndi zofunikira zina.
