Ingcamango yendawo yokukhusela umbane

Umbono wokhuseleko lombane uvumela ukucwangcisa, ukumilisela kunye nokubeka iliso kumanyathelo okhuseleko. Indawo ekhusela umbaneZonke izixhobo ezifanelekileyo, ufakelo, kunye neenkqubo kufuneka zikhuselwe ngokuthembekileyo kwinqanaba elifanelekileyo kwezoqoqosho. Ukuza kuthi ga ngoku, isakhiwo sahlulwe saziindawo ezinobungozi obahlukeneyo. Ngokusekwe kule mimandla, amanyathelo okhuseleko afunekayo anokumiselwa, ngakumbi izixhobo zombane kunye nezixhobo zokukhusela izixhobo.

I-EMC esekwe (EMC = ukuhambelana kombane) indawo yokhuseleko yombane ibandakanya ukukhuselwa kokukhanya kwangaphandle (inkqubo yokupheliswa komoya, umqhubi phantsi, umhlaba), ukudibanisa izixhobo, ukukhusela indawo kunye nokukhuselwa kokunikezelwa kwamandla kunye nenkqubo yetekhnoloji yolwazi. Iindawo zokukhusela umbane zichazwe ngezantsi.

Iindawo zokukhusela umbane kunye neendlela zokukhusela ngokubanzi

Izixhobo zokukhusela ezihluliweyo zihlelwa njengombane ababanjiweyo ngoku, ababanjiweyo, kunye nababanjiweyo ngokudibeneyo ngokweemfuno kwindawo yabo yofakelo. Umbane wangoku kunye nokudityaniswa kokubanjwa okufakelwe kutshintsho ukusuka kwi-LPZ 0A ukuya kwi-1 / LPZ 0A Ukufezekisa 2 ezona mfuno zingqongqo ngokubhekisele kumthamo wokukhupha. Aba babanjiweyo kufuneka babe nakho ukukhupha imibane yamaza ombane ayi-10/350 XNUMXs amaza amatyeli aliqela ngaphandle kwentshabalalo, oko ke kuthintela inaliti yombane oyonakalisayo kwinxalenye yombane kufakelo lombane lwesakhiwo.

Ukunyuka kokubanjwa kufakwe kutshintsho ukusuka kwi-LPZ 0B ukuya kwi-1 kunye nokuhla kombane obambayo ngoku kwindawo yotshintsho ukusuka kwi-LPZ 1 ukuya kwi-2 nangaphezulu. Umsebenzi wabo kukunciphisa intsalela yamanqanaba okhuselo anyukayo kunye nokunciphisa ama-surges anyanzeliswa kufakelo okanye aveliswe kufakelo.

Imilinganiselo echazwe ngombane kunye nokukhuseleka kokukhusela kwimida yemimandla yokhuseleko yombane kufuneka ithathelwe zombini ukunikezelwa kwamandla kunye neenkqubo zetekhnoloji yolwazi. Ukuphunyezwa okungaguquguqukiyo kwamanyathelo achaziweyo kuqinisekisa ukubakho ngokusisigxina kwezibonelelo ezikhoyo.

Inkcazo yemimandla yokhuseleko yombane

Ukukhuselwa kwe-LEMP kwezakhiwo ezinezixhobo zombane neze-elektroniki ngokungqinelana ne-IEC 62305-4

I-LPZ 0A  Indawo apho isoyikiso sibangelwe kukukhanya kombane ngokuthe ngqo kunye nentsimi yombane opheleleyo wombane. Iinkqubo zangaphakathi zinokuthi zixhomekeke kumbane opheleleyo wombane.

I-LPZ 0B  Indawo ekhuselweyo ngokuchasene nemibane ethe ngqo kodwa apho isoyikiso sisibane esipheleleyo sendawo yombane. Iinkqubo zangaphakathi zinokuthi zixhomekeke kwimibane yokunyuka kombane.

I-LPZ 1  Indawo apho i-current surge ikhawulelwe ngokwabelana kwangoku kunye nee-SPD kumda. Ukukhuselwa kwendawo kunokunciphisa intsimi yombane wombane.

I-LPZ 2  Indawo apho i-current current inokuncitshiswa ngokwabelana kwangoku kunye nee-SPD ezongezelelweyo kumda. Ukhuselo lomhlaba olongezelelekileyo lunokusetyenziselwa ukuqhubeka nokucutha intsimi yombane wombane.
