Umqondo wendawo yokuvikela umbani

Umqondo wendawo evikela umbani uvumela ukuhlela, ukusebenzisa nokuqapha izindlela zokuvikela. indawo evikela umbaniOnke amadivayisi afanele, ukufaka, kanye nezinhlelo kumele zivikelwe ngokuthembekile ngezinga elifanele lomnotho. Kuze kube manje, ibhilidi lihlukaniswe laba yizindawo ezinamathuba anobungozi ahlukahlukene. Ngokuya ngalezi zindawo, izindlela zokuvikela ezidingekayo zinganqunywa, ikakhulukazi, amadivayisi wezinto zombani nokuqhuma.

I-EMC-based (EMC = ukuhambisana kwe-electromagnetic) indawo yokuvikela umbani ifaka phakathi ukuvikelwa kokukhanya kwangaphandle (uhlelo lokuqeda umoya, umqhubi ophansi, ukuqhuma komhlaba), ukuqiniswa kwe-equipotential, ukuvikelwa kwendawo nokuvikelwa kokuphakelwa kohlelo lokuhlinzekwa kwamandla nolwazi lobuchwepheshe. Izindawo zokuvikela umbani zichazwe ngezansi.

Izindawo zokuvikela umbani nezindlela zokuvikela eziphelele

Imishini yokuvikela yokwanda ihlukaniswa njengababambi bamanje bonyazi, ababophi bokuqina, kanye nababoshiwe abahlanganisiwe ngokuya ngezidingo endaweni yabo yokufakwa. Umbani wamanje wokubopha kanye nokubopha okuhlanganisiwe okufakwe ekuguqukeni kusuka ku-LPZ 0A kuya ku-1 / LPZ 0A ukufeza izidingo eziqinile kakhulu ngokomthamo wokukhipha. Laba baboshiwe kumele bakwazi ukudedela imijikelezo yombani engaphelele yama-2/10 waves amagagasi kaningi ngaphandle kokubhujiswa, ngaleyo ndlela kuvinjelwe ukujovwa kwemisinga yombani eyonakalisayo engxenyeni kagesi yokufakwa kwesakhiwo.

Ama-Surge arresters afakiwe ekushintsheni kusuka ku-LPZ 0B kuya ku-1 nangaphansi komfula osibanji wamanje ekushintsheni kusuka ku-LPZ 1 kuye ku-2 nangaphezulu. Umsebenzi wabo ukunciphisa insalela yamabanga wokuvikela akhuphukayo nokukhawulela ama-surges abangelwa ukufakwa noma ukukhiqizwa ekufakweni.

Izinyathelo ezichazwe ngombani nezokuvikela emikhawulweni yezindawo zokuvikela umbani kufanele zithathelwe kokubili ukunikezwa kwamandla nezinhlelo zobuchwepheshe bolwazi. Ukusetshenziswa okungaguquguquki kwezinyathelo ezichaziwe kuqinisekisa ukutholakala unomphela kwengqalasizinda yesimanje.

Incazelo yezindawo zokuvikela umbani

Ukuvikelwa kwe-LEMP kwezakhiwo ezinezinhlelo zikagesi nezikagesi ngokuya nge-IEC 62305-4

I-LPZ 0A  Indawo lapho usongo lubangelwa ukukhanya okuqondile kombani kanye nensimu ephelele yombani kagesi. Izinhlelo zangaphakathi zingabhekelwa njengamanje umbani wokugcwala kombani.

I-LPZ 0B  I-Zone ivikelwe emibani eqondile kodwa lapho usongo luyi-full lightning field kagesi. Izinhlelo zangaphakathi zingabhekelwa yimisinga yokwanda kombani ngokwengxenye.

I-LPZ 1  Indawo lapho i-current surge ikhawulelwe ngokwabelana kwamanje nangama-SPD emngceleni. Ukuvikelwa kwendawo kunganciphisa inkambu yombane kagesi.

I-LPZ 2  Indawo lapho i-surge current ingahle ikhawulelwe ngokwabelana kwamanje nangama-SPD angeziwe emngceleni. Ukuvikelwa kwendawo okwengeziwe kungasetshenziselwa ukuqhubeka nokunciphisa amandla wensimu yombane.
