Pano pali mitundu yambiri ya zingwe, koma zofunika kwambiri zikhoza kugawidwa mu zingwe otsika-voteji ndi mkulu-voteji zingwe, koma kusiyanitsa awiri?Anthu ena amati ndi 250V, ndipo ena amati ndi 1000V.Kodi mumasiyanitsa bwanji ma voltages apamwamba ndi otsika?
Malinga ndi miyezo yamakampani aku China, zida zamagetsi zimagawidwa kukhala voteji yayikulu komanso yotsika: voteji yayikulu: zida zokhala ndi voteji pamwamba pa 250V mpaka pansi;otsika voteji: zida ndi voteji pamwamba 250V pansi.Malinga ndi malamulo a chitetezo cha mzere wamagetsi a 2009, ntchito yamagetsi imagawidwa kukhala magetsi apamwamba komanso otsika
Zida zamagetsi zamagetsi: mulingo wamagetsi ndi 1000V ndi kupitilira apo;zida zamagetsi zamagetsi zotsika: mulingo wamagetsi uli pansipa 1000V;
Nthawi zambiri, chingwe chamagetsi apamwamba chimatanthawuza chingwe cha 3 ~ 10kV;low voltage line amatanthauza 220/380 V mzere.
Njira yosiyanitsira voteji ya waya wapamwamba kwambiri ndi maso amaliseche ndi motere:
1. Dziwani kuchuluka kwa magetsi.
M'makampani aku China, ma voliyumu wamba ndi 220 V, 380 V, 1000 V, 10000 V, 35 000 V, 110 000 V, 220 000 V, 500 000 V, ndi zina zambiri. monga magetsi otsika, makamaka magetsi apakhomo;ndipo pamwamba pa 35000 V ndi magetsi apamwamba, omwe amagwiritsidwa ntchito kwambiri potumiza mphamvu.Pakati pa ziwirizi pali kupanikizika kwapakatikati.Ziyenera kunenedwa kuti kukhudza mawaya amphamvu kwambiri kapena kugwira ntchito yamoyo pansi pa mzerewu kuli ndi ngozi yayikulu.
2. Dziwani mizere yotsika yamagetsi.
Mzere wakunja wamagetsi otsika uli ndi zinthu zingapo zoonekeratu
1) Nthawi zambiri, mtengo wa simenti supitilira 5 metres.
2) Makulidwe a mawaya ndi ofanana, ndipo kuchuluka kwa mawaya kumachulukitsa 4. Izi zili choncho chifukwa mawaya otsika kwambiri amakhala ndi mawaya agawo atatu.Ngati zizindikirozi zilipo, zikhoza kudziwika kuti magetsi a mzere wa waya ndi 380 V ndipo gawo lamagetsi ndi 220 v.
3. Dziwani mizere yapakati ndi yamphamvu kwambiri.
Mizere yapakati ndi yamphamvu yamagetsi imakhalanso ndi mawonekedwe owonekera
1) Ngati makulidwe a mawaya ali ofanana, chiwerengero cha mawaya ndi ochuluka a 3. Izi ndichifukwa chakuti mizere yopatsirana nthawi zambiri imagwiritsa ntchito magawo atatu.Ngati izi zilipo, zitha kutsimikiziridwa kuti waya ndi 10000 volts.
2) Ngati makulidwe a waya ndi osiyana, chiwerengero cha mizere yakuda ndi yochuluka ya 3, ndipo pali mawaya awiri okha, omwe amaganiziridwa kuti ndi apamwamba kwambiri.Izi zili choncho chifukwa waya wochepa thupi sagwiritsidwa ntchito popereka mphamvu, koma chitetezo cha mphezi, chomwe chimatchedwanso mphezi.Ngati zizindikirozi zilipo, zikhoza kudziwika kuti waya ndi mzere wothamanga kwambiri.
4. Dziwaninso mzere wapamwamba wamagetsi.
Pofuna kupititsa patsogolo mphamvu yotumizira, mawaya okwera kwambiri nthawi zambiri amagwiritsa ntchito ma conductor ogawanika.Nthawi zambiri, waya umodzi umagwiritsidwa ntchito pagawo limodzi.Tsopano mitolo ingapo yamawaya imagwiritsidwa ntchito m'malo mwa woyambayo.Podziwa izi, n'zosavuta kuweruza mlingo wa voteji wa waya.1) Gawo limodzi ndi waya umodzi ndi 110000 volts;2) gawo limodzi ndi mawaya awiri ndi 220000 volts;3) gawo limodzi lokhala ndi mawaya anayi ndi 500000 volts.
Pakukhudzana kwathu kwa tsiku ndi tsiku ndi mizere yamagetsi apamwamba, koma pamaso pa mizere yapakati ndi yotsika kwambiri, tiyenerabe kusamala.Chaka chilichonse, anthu osawerengeka amafa ndi kugwedezeka kwa magetsi, kotero ziribe kanthu mtundu wa chingwe chomwe chikugwiritsidwa ntchito, tiyenera kugwiritsa ntchito chingwe chamtundu wa dziko ndi chitsimikizo cha khalidwe.Pofuna kupititsa patsogolo ubwino wa zinthuzo, zinthuzo zimapangidwa motsatira mfundo za dziko (GB / JB) ndi International Electrotechnical Commission (IEC).Kampaniyo yadutsa chiphaso cha ISO9001: 2008 chapadziko lonse lapansi, idalandira chiphaso chapadziko lonse lapansi chopanga zinthu zamakampani ndi China National Compulsory Product Certification (satifiketi ya CCC).Pakati pawo, ukadaulo wopanga chingwe cha XLPE chili patsogolo pamakampani, Pofuna kutsatira mosamalitsa kumangidwa kwa State Grid, kampaniyo idagulanso chingwe chapamwamba cha 35kV cholumikizira chingwe, sitepe imodzi yolumikizana ndi silane. mzere ndi zina zapamwamba waya ndi chingwe kupanga mizere.Ziribe kanthu mtundu wa chingwe, chingwe cha Zhujiang chidzakupatsani khalidwe labwino kwambiri!
