Lightning Protection Zone (LPZ)
Muchidimbu cheIEC, mashoko akafanana neaya 1 / 2 / 3 kana kuti class 1 / 2 / 3 chipikisi chekudzivirira chinonyanya kufarira. Muchikamu chino, tichazozivisa chirevo chakanyatsoenderana nemitemo yekare: nzvimbo yekudzivirira magetsi kana LPZ.
Ndeipi nzvimbo yekudzivirira magetsi uye nei ichikosha?
Iyo mheni yekudzivirira kwemhepo pfungwa inotangira uye inotsanangurwa muIEC 62305-4 chiyero icho chiri chinzvimbo chepasi rose chekudzivirira kwemheni. Pfungwa yeLPZ inoenderana nepfungwa yekudzora zvishoma nezvishoma magetsi emagetsi kune akachengeteka kuti asazokanganisa kukuvadzwa kwetemu.
Ngatione muenzaniso wakakosha.
Saka chii chinonzi nzvimbo dzakasiyana-siyana dzekudzivirira magetsi zvinoreva?
LPZ 0A: Inzvimbo isina kuchengetedzwa iri kunze kwechivako uye yakafumurwa kunongedza mheni yakananga. MuLPZ 0A, hapana chidziviriro chinopesana nemagetsi zvinokanganisa LEMP (Mheni Electromagnetic Pulse).
LPZ 0B: Sezvakaita LPZ 0A, iri kunze kwechivako asi LPZ 0B inodzivirirwa nekunze kwemhepo yekudzivirira magetsi, kazhinji mukati memharaunda yekudzivirira yemudonzvo wemheni. Zvakare, hapana chekudzivirira kurwisa LEMP zvakare.
LPZ 1: Ndiyo nzvimbo mukati meimba. Panzvimbo iyi, zvinokwanisika kune magetsi ane pari zvino aripo. Asi mheni iripo iyo yakadzika chaizvo sokuti hafu yeiyo inoitiswa pasi nekunze kwemheni inodzivirira system. Pakati peLPZ0B neLPZ1, panofanira kuva neClass 1 / Type 1 SPD yakagadzirirwa kuchengetedza zvigadziriswa.
LPZ2: Ichowo nzvimbo yeZimbabwe mukati meimba iyo inowanikwa pasi yakadzika. Pakati peLPZ2 neLPZ1, panofanira kuva nechikwata chechina 2 / Type2 Surge kudzivirira.
LPZ3: SaLPZ1 & 2, LPZ3 zvakare inzvimbo iri mukati meimba apo pasina kana mashoma mafungu emhepo.
