Chomera Chokwanira Chokwanira / Chotsika cha Voltage

GGD AC Low Voltage Power Distribution Cabinet

GGD AC otsika-voteji yogawa nduna ndi mtundu watsopano wa otsika-voteji kugawa nduna anakonza pa mfundo ya chitetezo, chuma, rationality ndi kudalirika malinga ndi zofunika za woyang'anira Unduna wa Mphamvu, ambiri ogwiritsa ntchito mphamvu ndi madipatimenti kapangidwe. Chogulitsacho chimakhala ndi kuthekera kwakukulu kwagawo, kukhazikika kwamphamvu komanso kutentha, chiwembu chosinthika chamagetsi, kuphatikiza kosavuta, kutheka kwamphamvu, kapangidwe kake komanso chitetezo chapamwamba. Itha kugwiritsidwa ntchito ngati chinthu chosinthidwa cha switchgear yotsika-voltage.

GGD AC otsika-voteji kugawa nduna ndi oyenera owerenga mphamvu monga magetsi zomera, substations, mafakitale ndi migodi, etc., ndi AC 50Hz, oveteredwa ntchito voteji 380V ndi oveteredwa ntchito panopa 3150A, ndipo ntchito mphamvu kutembenuka, kugawa ndi kulamulira mphamvu, kuyatsa ndi kugawa zida.

GGD AC low-voltage distribution cabinet ikugwirizana ndi IE0439 "Low-voltage switchgear and control gear", GB7251 "Low-voltage switchgear ndi miyezo ina".

Malo ogwirira ntchito

1. Kutentha kwa mpweya wozungulira sikokwera kuposa +40°C komanso sikutsika kuposa -5°C. Kutentha kwapakati mkati mwa maola 24 sikuyenera kupitirira + 35 ° C.

2. Kuyika ndi kugwiritsa ntchito m'nyumba, kutalika kwa malo ogwiritsira ntchito sikudutsa mamita 2000.

3. Chinyezi chamtundu wa mpweya wozungulira sichiyenera kupitirira 50% pa kutentha kwakukulu kwa + 40 ° C, ndipo kutentha kwakukulu kumaloledwa pa kutentha kochepa. (mwachitsanzo, 90% pa +20 ° C) Chikoka cha condensation chomwe chingachitike nthawi zina chifukwa cha kusintha kwa kutentha chiyenera kuganiziridwa.

4. Pamene zida zaikidwa, kupendekera kuchokera ku ndege yowongoka sikudutsa 5%.

5. Zidazi ziyenera kuikidwa pamalo omwe palibe kugwedezeka kwachiwawa komanso kumene zigawo za magetsi sizikuwonongeka.

6. Ogwiritsa ntchito amatha kukambirana ndi wopanga kuti athetse zofunikira zapadera.
