YN28-12 zida zochotseka AC zitsulo-zotsekedwa switchgear.Ndi oyenera magawo atatu AC mphamvu dongosolo ndi voteji oveteredwa 12kV ndi oveteredwa pafupipafupi 50Hz.Amagwiritsidwa ntchito kulandira ndi kugawa mphamvu zamagetsi ndikuwongolera, kuteteza ndi kuyang'anira mabwalo.
Zogwirizana ndi miyezo:
GB3906-2006 "3.6 ~ 40.5kV AC zotsekera switchgear ndi zida zowongolera" GB11022-89 "General technical condition for high-voltage switchgear" IEC298 (1990) "Voliteted voltage above 1kV and 50kV and below AC zitsulo-zotsekedwa switchgear ndi controlgear zida" DL404 -97 "Technical Conditions for Ordering Indoor AC High Voltage Switchgear"
Tanthauzo la Chitsanzo
Ntchito ndi Mbali
Switchgear idapangidwa molingana ndi zida zachitsulo zotsekeredwa mu GB3906-91.Chonsecho chili ndi magawo awiri: thupi la nduna ndi gawo lokwera lapakati (ie ngolo).Kabichi imagawidwa m'zipinda zinayi zosiyana, mulingo wachitetezo champanda ndi IP4X, ndipo mulingo pakati pa chipinda chilichonse ndi chitseko cha chipinda chophwanyira dera ndi IP2X ikatsegulidwa.Ili ndi mizere yolowera pamwamba ndi yotuluka, mizere yolowera ndi kutulutsa ndi njira zina zogwirira ntchito, zomwe zitha kukonzedwa ndikuphatikizidwa kuti apange zida zonse zogawa mphamvu zamagetsi.Chophimbacho chikhoza kukhazikitsidwa, kusinthidwa ndi kusungidwa kuchokera kutsogolo, kotero icho chikhoza kubwerera kumbuyo, chokonzekera kawiri ndikuyika pakhoma, chomwe chimapangitsa chitetezo, kusinthasintha ndi mapazi a switchgear.
Zomwe zimagwiritsidwa ntchito bwino
◆ Kutentha kwa mpweya wozungulira: kutentha kwakukulu +40 ℃.Kutentha kochepa -15 ℃.
◆ Chinyezi chachibale: pafupifupi tsiku lililonse chinyezi wachibale: ≤95%;Kuthamanga kwa tsiku ndi tsiku kwa nthunzi sikudutsa 2.2KPa;pamwezi pafupifupi chinyezi wachibale: ≤90%;Kuthamanga kwa mwezi uliwonse kwa nthunzi sikudutsa 1.8KPa;
◆ Kutalika: pansi pa 1000m.
◆ Kuchuluka kwa chivomerezi: osapitirira madigiri 8.
◆ Mpweya wozungulira sayenera kuipitsidwa mwachiwonekere ndi mpweya wowononga kapena woyaka, mpweya wamadzi, ndi zina zotero.
◆Palibe malo onjenjemera achiwawa.
◆Ngati ikugwiritsidwa ntchito motsatira zomwe zafotokozedwa mu GB3906, zili kwa wogwiritsa ntchito ndi kampaniyo kukambirana.
