GGD AC Low-Voltge Power Distribution Cabinet
Kuchuluka kwa Ntchito
GGD AC low-voltage power distribution cabinet ndi yoyenera kwa ogwiritsa ntchito magetsi monga magetsi, malo ocheperako, mabizinesi ogulitsa mafakitale ndi ogwiritsa ntchito magetsi ena monga AC 50HZ, oveteredwa ntchito voteji 380V, oveteredwa panopa kwa 3150A dongosolo kugawa mphamvu monga mphamvu, kuyatsa ndi mphamvu kutembenuka zida. , Kugawa ndi kulamulira.Zogulitsazo zimakhala ndi mphamvu zosweka kwambiri, zovotera kwakanthawi kochepa kupirira mpaka 50KAa, chiwembu chosinthika cha dera, kuphatikiza kosavuta, kuthekera kolimba, komanso kapangidwe kake.Chogulitsachi ndi chimodzi mwazinthu zomwe zimayimilira zida zomwe zasonkhanitsidwa komanso zokhazikika m'dziko langa.
Izi zikugwirizana ndi IEC439 "Low-Voltage Switchgear and Control Equipment", GB7251.12-2013 "Low-Voltage Switchgear ndi Control Equipment Gawo 2: Malizitsani Kusintha kwa Mphamvu ndi Zida Zowongolera" ndi miyezo ina.
GGD AC low-voltage power distribution cabinet ndi yoyenera kwa ogwiritsa ntchito magetsi monga magetsi, malo ocheperako, mabizinesi ogulitsa mafakitale ndi ogwiritsa ntchito magetsi ena monga AC 50HZ, oveteredwa ntchito voteji 380V, oveteredwa panopa kwa 3150A dongosolo kugawa mphamvu monga mphamvu, kuyatsa ndi mphamvu kutembenuka zida. , Kugawa ndi kulamulira.
Mikhalidwe Yachilengedwe
1. Kutentha kwa mpweya wozungulira sikuposa +40℃ndipo osachepera -5℃.Kutentha kwapakati mkati mwa maola 24 sikuyenera kupitirira +35℃.
2. Pakuyika ndikugwiritsa ntchito m'nyumba, kutalika kwa malo ogwiritsira ntchito sikudutsa 2000m.
3. Chinyezi chachifupi cha mpweya wozungulira sichidutsa 50% pamene kutentha kwakukulu ndi +40℃, ndi chinyezi chapamwamba kwambiri chimaloledwa pa kutentha kochepa: (mwachitsanzo, 90% pa +20℃), ziyenera kuganiziridwa kuti kutentha kungasinthe Mwangozi zotsatira za condensation.
4. Zida zikayikidwa, kupendekera kwa ndege yoyima sikuyenera kupitirira 5°.
5. Zidazi ziyenera kuikidwa m'malo omwe kulibe kugwedezeka kwakukulu ndi kukhudzidwa, ndi malo omwe zigawo za magetsi sizikuwonongeka.
6. Pamene wogwiritsa ntchito ali ndi zofunikira zapadera, zikhoza kuthetsedwa mwa kukambirana ndi wopanga.
Chitsanzo ndi Tanthauzo Lake
The Main Technical Parameters
1. Zofunikira zamagetsi zamagetsi zikuwonetsedwa mu Gulu 1
| chitsanzo | Mphamvu yamagetsi (V) | Zovoteledwa pano (A) | Zovoteledwa ndi Short circuit switching current (KA) | Kuvoteledwa kwakanthawi kochepa (IS)(KA) | Peak yoyezedwa kupirira panopa (KA) | |

2. Dongosolo lothandizira dera
Mapangidwe a dera lothandizira amagawidwa m'magawo awiri: dongosolo lamagetsi ndi dongosolo lamagetsi.
3. Basi yaikulu
Pamene ovotera panopa ndi 1500A ndi pansi, basi imodzi yamkuwa imagwiritsidwa ntchito.Mabasi ovotera akakula kuposa 1500A, mabasi amkuwa awiri amagwiritsidwa ntchito.Pamwamba pa mabasi onse amapangidwa ndi malata.
4. Kusankhidwa kwa zigawo zamagetsi
a.Kabichi ya GGD imagwiritsa ntchito zida zamagetsi zapamwamba kwambiri zomwe zimatha kupangidwa mochuluka ku China.Monga DW17, DZ20, DW15, etc.
b.Kusintha kwa mpeni kwa 1ID13BX ndi HS13BX ndi zigawo zapadera zomwe zinapangidwa ndi NLS kuti zigwirizane ndi zosowa zapadera za nduna ya GGD.Imasintha kagwiritsidwe ntchito ka makinawo ndikusunga zabwino zazinthu zakale.Ndi mtundu watsopano wothandiza wa gawo lamagetsi.
c.Mwachitsanzo, dipatimenti yokonza mapulani ikasankha zida zatsopano zamagetsi zomwe zimagwira ntchito bwino komanso ukadaulo wapamwamba kwambiri malinga ndi zosowa za ogwiritsa ntchito, chifukwa nduna ya GGD ili ndi kusinthasintha kwabwino kwa kukhazikitsa, sizingayambitse zovuta kupanga ndi kukhazikitsa chifukwa cha zida zamagetsi zomwe zasinthidwa.
d.Pofuna kupititsa patsogolo kukhazikika kwa dera, thandizo la mabasi la nduna ya GGD limatenga mtundu wodzipereka wa ZMJ wophatikiza mabasi ndi chithandizo cha insulating.Chotchinga cham'basi chimapangidwa ndi zinthu zamphamvu kwambiri, zoletsa moto wa PPO, zokhala ndi mphamvu zotsekereza, zozimitsa bwino, komanso mawonekedwe apadera.Itha kuphatikizidwa mosavuta kukhala busbar imodzi kapena clamp iwiri ya mabasi posintha malo omangira.Thandizo lotetezera ndi mawonekedwe opangidwa ndi manja okhala ndi mtengo wotsika komanso mphamvu zambiri, zomwe zimathetsa zolakwika za mtunda wosakwanira wa creepage wa zinthu zakale.
Kuitanitsa Malangizo
Poyitanitsa, wogwiritsa ntchito ayenera kupereka izi:
1. Chitsanzo chonse cha mankhwala (kuphatikizapo chiwerengero chachikulu cha dongosolo la dera ndi nambala yothandizira dera).
2. Waukulu wozungulira dongosolo kuphatikiza zinayendera chithunzi.
3. Chithunzi chojambula chamagetsi cha dera lothandizira.
4. Mndandanda wa zigawo mu nduna.
5. Zofunikira zina zapadera zomwe sizikugwirizana ndi zomwe zimagwiritsidwa ntchito mwachizolowezi.
