1. Qauv Qauv Kev Txhais Lus
Disconnector Qauv Codes ib txwm muaj xws li cov qauv tsim qauv, voltage chav kawm, muaj peev xwm siv tau xwm txheej tam sim no, thiab kev thov kev xaiv. Piv txwv:
Gn 30-12thiabGn 19-12 c:
Gn: "Nyob sab hauv tsev siab-voltage disconnector" (g=disconnector, n=hauv tsev).
Cov lej lej: "30" lossis "19"=qauv tsim; "12" {{{{{}}} Cov voltage 12 kv; "C" {{= nruab nrog cov hniav hniav.
Kev ntsuas tam sim no: Xws li, "630a" qhia tias muaj kev ntaus nqi tam sim no ntawm 630A. Kev xaiv yuav tsum tshaj lub kaw lus lub nra ntau tshaj plaws los ntawm 20 feem pua npoo.
Cov cim ntxiv:
Tus st: Cov tshuaj muaj kuab paug-tiv taus hom.
Txawb CST: Plateau-adapted purgeion-resistant hom (rau cov chaw hnyav).
Cov Ntsiab Lus Pariusion
Cov Ntsuas Hluav Taws Xob: Yuav tsum muaj ntau dua lossis sib npaug ntawm cov kab ke rau cov haujlwm ua haujlwm siab tshaj plaws (piv txwv li, 12 kV rau 10 kV lub tshuab).
Lub sijhawm luv luv withstand tam sim no (icw): Yuav tsum phim cov kab ke luv luv-circuit Court tam sim no. Cov Qauv:
ICW ntau dua los yog sib npaug ntawm kev ua txhaum luv luv ntawm cov sijhawm tam sim no × sijhawm.Inw lub sij hawm tam sim no Circuitive Circuit Court tam sim no × kev txhaum sijhawm ntev / sijhawm.
Neeg Kho Tshuab 10:
M2 chav kawm (10, 000 cmles): cov ntawv thov dav dav.
M3 chav kawm (30, 000 cmles):: nquag ua haujlwm (piv txwv li, kev tsheb ciav hlau / kev tsheb nqaj hlau / kev tsheb nqaj hlau).
2. Sab nraum zoov vs. Sab Hauv Tsev Disconnector Txawv
Kev Tiv Thaiv Kev Tiv Thaiv:
Sab nraum zoov: IP65 lossis siab dua (plua plav / waterproof), piv txwv li, gn 19-12 cst (toj siab-resistant).
Nyob Sab Hauv Tsev: Feem ntau IP40, nrog rau kev saib xyuas kom ua haujlwm kub dissipation.
Kev Kawm Txog: Sab hauv tsev units ua yuam kev ua yuam kev ua rau sab nraum zoov uas ua rau cov rwm thaiv tsis ua tiav vim dej nag.
Cov Khoom Siv & Corrosion Kuj:
Thaj chaw Nqaum: 304 stainless hlau lossis galvanized txheej.
Arctic cheeb tsam: {-40 degree tsawg daim ntawv pov thawj.
Kev Lag Luam Kev Lag Luam:
Sab Nrauv Sab Nraum: Peb-phase txuas tshuab.
Nyob sab hauv tsev: phau ntawv lossis ib leeg-ncej ua haujlwm.
Kho:
Sab Nraum: Cov plua plav tsis tu ncua tshem tawm thiab tiv thaiv corrosion corrosion.
Nyob sab hauv tsev: Tsom mus txog kev sib cuag oxidation thiab roj nplua nyeem kev txwv.
3. Xaiv Pitfalls & Cov Lus Taw Qhia
Pitfall 1: Tsis quav ntsej ib puag ncig kev yoog tau. Piv txwv li: Siv cov qauv qauv hauv cov chaw ua haujlwm yam tsis muaj kev cuam tshuam los ua rau muaj kev kub ntxhov.
Zwj 2: Tsis meej Disconnectors Nrog Load Sweetes, pheej hmoo arc ua txhaum.
Lus pom zoo:
Muab thawj cov ntawv pov thawj ib puag ncig (piv txwv li, kev ua qias / toj siab).
Siv tau ICW thiab kev ua haujlwm thev naus laus zis tiv thaiv kev xav tau.
Siv cov qauv kev tsim tshwj xeeb rau kev nthuav tawm.
