Iindaba zeshishini

I-125 15KA Miniature Circuit Breaker yenzelwe iinkqubo zombane ezifuna zombini umthamo ophezulu wangoku kunye nokhuseleko oluthembekileyo olufutshane. Ngokungafaniyo nee-MCB eziqhelekileyo ezikumgangatho ophantsi, isixhobo se-125A esinomthamo ophezulu wokwaphuka sinokujongana nezicelo ezifunwayo zokusasaza apho imisinga yempazamo inokuba phezulu kakhulu. Eli nqaku lichaza indlela i-125 15KA MCB esebenza ngayo, yintoni inkcazo yayo ephambili ithetha, apho ingasetyenziselwa khona, indlela yokukhetha nokuyifaka ngokuchanekileyo, kwaye ngawaphi amaqela okuthenga kufuneka ahlolisise ngaphambi kokubeka umyalelo.

I-6kA AC Miniature Circuit Breaker isetyenziswa ngokubanzi kwizicelo zokusasazwa kwe-voltage ephantsi kuba i-6kA yayo ilinganiswe kwi-short-circuit breaking capacity ibonelela ngenqanaba elisebenzayo lokuphazamiseka kwangoku kwiisekethe ezininzi zokuhlala, zorhwebo, kunye nezilula zoshishino. Nangona kunjalo, ixabiso le-6kA yinxalenye enye yenkqubo yokukhetha. Ireyithingi yangoku, amandla ombane, ijiko lohambo, ulungelelwaniso lwepali, indawo yofakelo, kunye nemigangatho esebenzayo nayo kufuneka ivavanywe.

I-RCBO - i-residual current circuit breaker with over current protection - is a low-voltage device protective device edibanisa ukukhuselwa komthwalo ogqithisiweyo, ukukhuselwa kwesiphaluka esifutshane kunye ne-residual current (ukuvuza) ukufunyanwa kwiyunithi enye ebunjiweyo.

Ishishini lamandla lehlabathi liya lixhomekeke ngakumbi kumbane othe ngqo. I-Solar photovoltaic arrays, iinkqubo zokugcina amandla ebhetri, izikhululo zokutshaja iimoto zombane, izixhobo zonxibelelwano, kunye namaziko edatha zonke ziqulethe amacandelo abalulekileyo e-DC. Njengoko ezi zicelo zandisa, ukukhuselwa kweesekethe zihamba ukusuka kwicandelo elixhasayo ukuya kwindawo ephakathi yokhuseleko lwenkqubo. Isaphuli sesekethe yeDC kufuneka siqhawule umsinga ongaqhelekanga ngokukhawuleza nangokukhuselekileyo, sithintele umonakalo kwiintambo, iziguquli, iibhetri, kunye nezixhobo eziqhagamshelweyo.

I-MCCB - i-molded case circuit breaker - isixhobo sokukhusela i-low-voltage esikhupha ngokuzenzekelayo isiphaluka xa sibona ukugqithiswa okanye iimeko ezimfutshane.

I-Miniature Circuit Breaker DPN 6KA yenzelwe ukubonelela ngokhuseleko oluthembekileyo kwi-overload kunye neesekethe ezimfutshane ngelixa udibanisa imilinganiselo ehlangeneyo kunye nofakelo olusebenzayo. Ukucwangciswa kwe-DPN ngokuqhelekileyo kuhambelana nolungiselelo lwe-1P + N, ngelixa i-6KA ibhekisela kwi-6 kA elinganiswe kwi-short-circuit breaking capacity phantsi kwemigangatho esebenzayo kunye neemeko zovavanyo ezichaziweyo.
