N’chifukwa chiyani chotetezera ma surge chiyenera kuyikidwa m’bokosi logawira?

Kodi ntchito yachipangizo choteteza kugwedezeka kwa mafunde(SPD) mu bokosi logawa:
Choteteza ma surge chimayikidwa kumbuyo kwa cholowetsa ma input circuit breaker mkati mwa bokosi logawa, ndipo ntchito yake yayikulu ndi kuteteza ma lightning. Dzina lake lonse ndi: choteteza ma surge ma surge.
Chipangizo choteteza mphamvu zamagetsi chopitirira muyeso ichi ndi choteteza ku ngozi za mphezi, ndipo ndikofunikiranso kuganizira mphamvu zamagetsi zopitirira muyeso zomwe zili mu mzere wogawa magetsi otsika. Ndi chipangizo choteteza chofunikira kwambiri mu dongosolo lamagetsi otsika.
Mvula yamkuntho imateteza bokosi logawa ku ziwopsezo za mphezi, ndipo mphamvu yamagetsi imakhala yokwera, ndipo mphamvu yayikulu imatsikira mwachangu padziko lapansi kuchokera ku waya woteteza mphezi. Chipangizo choteteza mafunde ndicho chimayang'anira ntchito yathu ya tsiku ndi tsiku yoteteza.
Zoteteza ku ma surge ndi zoyenera m'malo osiyanasiyana:
Kawirikawiri imayikidwa m'mabokosi ogawa, malo osungira makompyuta, zipinda zolumikizirana, zipinda zowongolera elevator, zipinda za TV ya chingwe, zipinda zowongolera zokha zomangira, malo ozimitsa moto, zipinda zowongolera zokha zamafakitale, zipinda zowongolera zida zosinthira pafupipafupi, zipinda zogwirira ntchito kuchipatala, zipinda zosamalira odwala kwambiri ndi mabokosi ogawa omwe ali ndi zida zamagetsi zamankhwala, ndi zina zotero. Kuphatikiza apo, imatha kuyikidwanso m'bokosi lalikulu logawa magetsi m'nyumba zokhala pansi pa zipinda zisanu ndi chimodzi.
Momwe mungakonzere chotetezera mphamvu mu bokosi logawa:
SPDZingagawidwe m'magulu awiri: chitetezo cha mphezi cha Gulu A, Gulu B, Gulu C, ndi Gulu D, zomwe zimatsimikiziridwa malinga ndi mphamvu ya magetsi ndi mphamvu ya bokosi logawa. Kugawa kwa 380V kumagwiritsa ntchito chitetezo cha mphezi cha Gulu B, 40KA~60KA. Bokosi logawa la 220V limagwiritsa ntchito chitetezo cha mphezi cha Gulu C, 20KA~40KA.
N’chifukwa chiyani bokosi logawiramo zinthu liyenera kukhala ndi chotetezera ma surge?
Panthawi yotulutsa mphezi, mphamvu yamagetsi imakhala yokwera, mphamvu yamagetsi imakhala yayikulu, ndipo nthawi yotulutsa mphamvu imakhala yochepa. Sikokwanira kungodalira chitetezo cha mphezi zakunja (ndodo za mphezi, ndi zina zotero). Mafunde amphezi adzalowa mwachindunji kapena mwanjira ina m'mizere yamagetsi, mizere yazizindikiro, mizere yolumikizira ma antenna, ndi mapaipi achitsulo. Mphezi ndi mphamvu yamagetsi yochokera pamenepo zidzawononga kwambiri zida zamagetsi, zamagetsi, ndi makina azidziwitso.
Kuwonongeka komwe kumachitika chifukwa cha mphezi ndi chimodzi mwa ngozi zazikulu zachilengedwe. Mphamvu yotsalira yamagetsi ndi mphezi yoyambitsa magetsi yomwe imapangidwa ndi mphezi imakhudzabe zida zamagetsi zomwe zimagwiritsidwa ntchito m'nyumba, zomwe zimapangitsa kuti zida zamagetsi zomwe zimagwiritsidwa ntchito m'nyumba zisamayende bwino, zomwe zimapangitsa kuti zinthu ziwonongeke mwachindunji monga kuyaka ndi kuphulika.
