Monga gawo lalikulu la machitidwe oteteza mphezi, kusankha ndodo yoyenera ya mphezi kumakhudza mwachindunji chitetezo cha nyumba. Chisankhochi chiyenera kulinganiza zofunikira zaukadaulo, zinthu zachilengedwe, komanso kutsatira malamulo.
1. Sankhani Kusankha Kutengera Magwiridwe Antchito
Franklin Rods: Yoyenera nyumba zokhala ndi malo oteteza a 30m. Imafunika chitsulo chopangidwa ndi galvanized ndi ma grounding grids apadera.
Ndodo za ESE (Early Streamer Emission): Onetsani mtunda wa 100m pogwiritsa ntchito electronic triggering, yoyenera malo ofunikira monga malo osungira deta. Tsimikizani ziphaso za CE/UL.
Ndodo Zotulutsa Ma Radiyo (Zoletsedwa): Zoletsedwa m'nyumba zatsopano zaku China pa GB 50057 iliyonse kuyambira 2005 chifukwa cha zoopsa za ma radiyo.
02. Uinjiniya Wokhudza Zachilengedwe
Kuwerengera Kutalika: Gwiritsani ntchito njira yozungulira ya mpira $ h = \sqrt{2rH – H^2}$ (h: kutalika kwa ndodo, r: kutalika kwa mpira, H: kutalika kwa kapangidwe)
Kukana Kudzikundikira: Gwiritsani ntchito chitsulo chosapanga dzimbiri cha 316L (kukana kupopera mchere >720hr) m'madera a m'mphepete mwa nyanja; copper-titanium alloy (pH 2-12 tolerance) m'malo omwe mankhwala amaperekedwa.
Kuchuluka kwa mphezi: M'madera omwe kuli zochitika zambiri (masiku opitilira 90 a mvula pachaka), onjezerani ma electrode oyambira ndi 25%.
03. Kukhazikitsa Kotsatira Malamulo
Gawo Lopanga: Sungani kukana kwa nthaka <10Ω (<4Ω pa malo apadera), gwiritsani ntchito makina opangira nthaka a TN-S/TT
Kapangidwe: Ikani chowotcherera cha thermite pa ma air terminals/down conductors okhala ndi >12cm yolumikizana
Kuyang'anira: Yesani impedance ya impulse kudzera mu CDM-10 pulse current mita; onetsetsani kuti ikugwirizana ndi zithunzi za infrared.
Malangizo Okonza: Yang'anirani kukana kwa nthaka pogwiritsa ntchito ma micro-ohmmeters kawiri pachaka, sinthani zophimba za conductor zaka 5 zilizonse kuti muwonetsetse kuti IEC 62305 ikutsatira malamulo onse a chitetezo.
