Indawo yokuKhusela uMbane (LPZ)
Kwimiqathango ye-IEC, imiqathango efana nohlobo lwe-1 / 2 / 3 okanye iklasi ye-1 / 2 / 3 ifowuni yokukhusela ithandwa kakhulu. Kule nqaku, siya kuzisa umxholo ohambelana kakhulu nemimiselo yangaphambili: indawo yokukhusela umbane okanye i-LPZ.
Iyintoni indawo yokukhusela umbane kwaye kutheni kubalulekile?
Umbono wokukhusela umbane uvela kwaye uchazwe kumgangatho we-IEC 62305-4 oyindlela yezizwe ngezizwe yokukhusela umbane. Ingcinga ye-LPZ isekwe kwingcamango yokunciphisa ngokuthe ngcembe amandla ombane kwinqanaba elikhuselekileyo ukuze lingabangeli monakalo kwisixhobo esibulalayo.
Masibone umzekeliso osisiseko.
Ngoko yintoni enye indawo ekhuselekileyo yokukhusela umbane?
I-LPZ 0A: Yindawo engakhuselekanga engaphandle kwesakhiwo kwaye ichanekile ekubetha kombane ngqo. Kwi-LPZ 0A, akukho kukhuselwa ekuphazanyisweni kwe-electromagnetic pulses LEMP (Umbane we-Electromagnetic Pulse).
I-LPZ 0B: NjengoLPZ 0A, iphinde ingaphandle kwesakhiwo kodwa iLPZ 0B ikhuselwe yinkqubo yangaphandle yokukhusela umbane, ngokuqhelekileyo kwindawo yokukhusela yendonga yombane. Kwakhona, akukho nto yokukhusela i-LEMP.
I-LPZ 1: Yona mda ngaphakathi kweso sakhiwo. Kule ndawo, kunokwenzeka ukuba kukho umbane okhoyo okwangoku. Kodwa umbane okwangoku uphantsi kakhulu ubuncinane ubuncinane isiqingatha saso senziwa phantsi ngombane wendlela yokukhusela yombane. Phakathi kweLPZ0B kunye neLPZ1, kufuneka kubekho iCandelo 1 / Udidi lwe-1 SPD efakwe ukukhusela izixhobo eziphantsi.
I-LPZ2: Kwakhona ummandla wendawo ngaphakathi kwesakhiwo apho kunokwenzeka khona ukuhamba okuphantsi. Phakathi kweLPZ2 kunye neLPZ1, kufuneka kube neClass 2 / Type2 isixhobo sokukhusela i-Surge.
I-LPZ3: Njenge-LPZ1 kunye ne-2, i-LPZ3 ikwayindawo ngaphakathi kwesakhiwo apho kungekho khona okanye kuncinci ukunyusa imisinga.
