Umahluko phakathi kwentambo yombane ophantsi kunye nentambo yombane ophezulu

Nazi iintlobo ezininzi zeentambo, kodwa ezona zisisiseko zinokwahlulwa zibe ziintambo ezine-voltage ephantsi kunye neentambo zombane ophezulu, kodwa ungahlula njani ezi zimbini?Abanye abantu bathi yi-250V, kwaye abanye bathi yi-1000V.Uwahlula njani amandla ombane aphezulu kunye noxinzelelo oluphantsi?

Ngokwemigangatho yoshishino yaseTshayina, izixhobo zombane zahlulwe zibe yi-voltage ephezulu kunye ne-low voltage: i-voltage ephezulu: izixhobo ezine-voltage ngaphezu kwe-250V ukuya emhlabeni;amandla ombane aphantsi: izixhobo ezinombane ongaphezulu kwe-250V ukuya emhlabeni.Ngokwemigaqo yokhuseleko lombane we-2009, umsebenzi wombane uhlukaniswe ube ngumbane ophezulu kunye nombane ophantsi

Izixhobo zombane zamandla aphezulu: inqanaba lombane li-1000V nangaphezulu;izixhobo zombane ombane ophantsi: inqanaba lombane lingaphantsi kwe-1000V;

Ngokubanzi, umgca wamandla ombane aphezulu ubhekisa kumgca we-3 ~ 10kV;umgca we-voltage ephantsi ubhekisela kumgca we-220 / 380 V.

Indlela yokwahlula i-voltage ye-voltage ephezulu ye-voltage ngamehlo ahamba ngolu hlobo lulandelayo:

1. Yazi inqanaba lombane.

Kwishishini lamandla eTshayina, amanqanaba ombane aqhelekileyo angama-220 V, 380 V, 1000 V, 10000 V, 35 000 V, 110 000 V, 220 000 V, 500 000 V, njl. Ngokuqhelekileyo, i-220 V kunye ne-380 V iqwalaselwa. njengamandla ombane aphantsi, ngakumbi kumbane wasekhaya;kwaye ngaphezu kwe-35000 V ziphezulu zombane, ezisetyenziselwa ukuhanjiswa kwamandla.Phakathi kwezi zimbini kukho uxinzelelo oluphakathi.Kufuneka kucaciswe ukuba ukubamba iingcingo eziphezulu ze-voltage okanye ukwenza umsebenzi ophilayo phantsi komgca kunengozi enkulu.

2. Chonga imigca yombane ophantsi.

Umgca wombane ophantsi wangaphandle uneempawu ezininzi ezicacileyo

1) Ngokuqhelekileyo, ipali yesamente ayikho ngaphezu kweemitha ezi-5.

2) Ubukhulu beentambo bufana, kwaye inani leentambo liphindaphindwe ka-4. Oku kungenxa yokuba iingcingo eziphantsi-voltage ngokubanzi zithatha inkqubo yocingo lwesigaba sesine.Ukuba ezi mpawu zikhoyo, kunokumiselwa ukuba i-voltage yentambo yocingo yi-380 V kunye ne-voltage yesigaba i-220 v.

3. Chonga imigca yombane ophakathi kunye nophezulu.

Imigca yamandla ombane aphakathi naphezulu nayo ineempawu ezicacileyo

1) Ukuba ubukhulu beengcingo bufana, inani leentambo liphindwe kabini.Ukuba ezi mpawu zikhoyo, kunokumiselwa ngokusisiseko ukuba ucingo luyi-10000 volts.

2) Ukuba ubukhulu bocingo buhluke, inani lemigca eshinyeneyo liphinda-phinda le-3, kwaye kukho iingcingo ezimbini ezinqabileyo kuphela, ezithathwa njengeyona ndawo iphakamileyo.Oku kungenxa yokuba ucingo olubhityileyo alusetyenziselwa ukuhanjiswa kwamandla, kodwa kukhuseleko lombane, okwaziwa ngokuba ngumqhubi wombane.Ukuba ezi mpawu zikhoyo, kunokumiselwa ukuba ucingo luyi-high-voltage line.

4. Ukuchonga ngakumbi umgca wamandla ombane aphezulu.

Ukuze kuphuculwe umthamo wothumelo, iingcingo eziphezulu ze-voltage ngokubanzi zisebenzisa abaqhubi abahlukeneyo.Ngokuqhelekileyo, ucingo olunye lusetyenziselwa isigaba esinye.Ngoku kusetyenziswa iinyanda ezininzi zocingo ukufaka indawo yeyokuqala.Ukwazi oku, kulula ukugweba inqanaba le-voltage yocingo.I-1) Isigaba esinye esinocingo olunye yi-110000 volts;2) isigaba esinye esineentambo ezimbini yi-220000 volts;3) isigaba esinye esineengcingo ezine yi-500000 volts.

Ekudibaneni kwethu kwansuku zonke kunye nemigca ye-voltage ephezulu, kodwa phambi kwemigca ephakathi kunye ne-low-voltage, kusafuneka siqaphele.Nyaka ngamnye, abantu abaninzi bafa ngenxa yokutshatyalaliswa kombane, ngoko ke kungakhathaliseki ukuba luhlobo luni lwentambo esetyenziswayo, kufuneka sisebenzise intambo esemgangathweni yesizwe kunye nokuqinisekiswa komgangatho.Ukuze kuphuculwe umgangatho weemveliso, iimveliso ziveliswa ngokungqongqo ngokuhambelana nemigangatho kazwelonke (GB / JB) kunye ne-International Electrotechnical Commission (IEC).Ishishini liphumelele ISO9001: 2008 isiqinisekiso somgangatho wamazwe ngamazwe, ifumene ilayisenisi yemveliso yemveliso yelizwe kunye neSatifikethi seMveliso eSinyanzelo saseTshayina (isatifiketi seCCC).Phakathi kwabo, iteknoloji yokuvelisa intambo ye-XLPE iphambili kwishishini, Ukuze ulandele ngokusondeleyo ukwakhiwa kweGridi kaRhulumente, inkampani iphinde yathenga i-35kV umgca wokuvelisa i-cable cross-linked, inyathelo elinye le-silane cross-linked production. umgca kunye nezinye iintambo eziphambili kunye nemigca yokuvelisa intambo.Kungakhathaliseki ukuba luhlobo luni lwekhebula, intambo yeZhujiang iya kuhlala ikunika umgangatho obalaseleyo!
