Ua ib feem tseem ceeb ntawm cov txheej txheem tiv thaiv xob laim, kev xaiv cov pas nrig xob laim kom raug cuam tshuam ncaj qha rau kev nyab xeeb ntawm lub tsev. Kev txiav txim siab yuav tsum sib npaug cov lus qhia txog kev siv tshuab, cov yam ntxwv ib puag ncig, thiab kev ua raws li txoj cai.
1. Kev Xaiv Hom Los Ntawm Kev Ua Haujlwm
Cov Hlau Franklin: Haum rau cov tsev nyob uas muaj 30m tiv thaiv vojvoog. Yuav tsum tau ua los ntawm cov hlau galvanized thiab cov grounding grid tshwj xeeb.
ESE (Early Streamer Emission) Rods: Nthuav qhov kev pab them nqi mus txog 100m siv hluav taws xob triggering, zoo tagnrho rau cov chaw tseem ceeb xws li cov chaw khaws ntaub ntawv. Xyuas kom meej cov ntawv pov thawj CE/UL.
Cov Qws Radioactive (Txwv): Txwv tsis pub siv rau hauv cov tsev tsim kho tshiab hauv Suav teb raws li GB 50057 txij li xyoo 2005 vim muaj kev phom sij ntawm cov hluav taws xob.
02. Kev Tsim Kho Ib puag ncig
Kev Xam Qhov Siab: Siv txoj kev dov lub voj voog $ h = \sqrt {2rH - H^2} $ (h: qhov siab ntawm tus pas nrig, r: lub vojvoog ntawm lub vojvoog, H: qhov siab ntawm cov qauv)
Kev Tiv Thaiv Kev Xeb: Siv 316L stainless hlau (tsis kam rau ntsev tsuag > 720 teev) hauv thaj chaw ntug dej hiav txwv; tooj liab-titanium alloy (pH 2-12 kam rau siab) rau cov cheeb tsam tshuaj lom neeg
Xob laim Ceev: Hauv thaj chaw muaj kev ua ub ua no ntau (>90 hnub muaj cua daj cua dub txhua xyoo), nce cov electrodes grounding los ntawm 25%.
03. Kev Teeb tsa raws li Code
Theem Tsim: Tswj kev tiv thaiv av <10Ω (<4Ω rau cov chaw tshwj xeeb), siv TN-S/TT earthing systems
Kev Tsim Kho: Siv cov thermite vuam rau cov cua terminals / down conductors nrog > 12cm overlap
Kev Tshuaj Xyuas: Sim cov impedance ntawm CDM-10 pulse current meters; xyuas kom meej tias lawv sib txuas nrog cov infrared imagers
Lub Tswv Yim Txog Kev Txij Nkawm: Saib xyuas qhov tsis kam ntawm av nrog cov micro-ohmmeters txhua ob xyoos ib zaug, hloov cov txheej txheej tiv thaiv kab hluav taws xob txhua 5 xyoos kom ntseeg tau tias ua raws li IEC 62305 thoob plaws lub voj voog tiv thaiv.
