Zaɓi waya gwargwadon ƙimar da aka yarda da ƙarfin ɗaukar waya na yanzu

Ya kamata a zaɓi ɓangaren giciye na waya na cikin gida bisa ga ikon ɗaukar wayan na yanzu, ƙimar asarar wutar lantarki da aka yarda da layin, da ƙarfin injin waya.Gabaɗaya, ana zaɓar saman da ke ɗauke da waya bisa ga ikon ɗaukar halin yanzu, sannan ana aiwatar da tabbatarwa gwargwadon wasu sharuɗɗan.Idan sashin giciye bai dace da buƙatun wani yanayin daidaitawa ba, yakamata a zaɓi madugu bisa ga mafi ƙanƙancin abin da ba zai iya cika sharadi ba.

Wuya mai ƙyalli mai ƙyalli: Ƙarƙashin ƙyalli na waya kuma ana kiransa amintaccen rashin ƙarfi ko amintaccen ƙimar waya.Matsakaicin zafin aiki da aka yarda da shi na wayar gaba ɗaya shine 65°C.Idan yanayin zafi ya wuce wannan zafin jiki, murfin murfin waya zai yi saurin tsufa, lalacewa da lalacewa, kuma yana iya haifar da wuta.Abin da ake kira izinin yanzu yana ɗaukar ƙarfin waya shine matsakaicin ƙimar halin yanzu wanda za'a iya wucewa na dogon lokaci lokacin da zafin aiki bai wuce 65 ° C ba.

Tun da zafin aiki na waya ba wai kawai yana da alaƙa da halin yanzu da ke wucewa ta hanyar waya ba, amma kuma yana da alaka da yanayin zafi na waya da kuma yanayin zafi, damar da ake iya ɗauka na yanzu na waya ba ƙayyadadden ƙima ba ne.Lokacin da waya ɗaya ta ɗauki hanyoyin kwanciya daban-daban (Hanyoyin kwanciya daban-daban, yanayin ɓarkewar zafinta shima ya bambanta) ko kuma a yanayin yanayin yanayi daban-daban, ikon ɗaukar halin yanzu shima ya bambanta.Koma zuwa littafin fasaha na lantarki don damar ɗaukar nauyin wayoyi tare da hanyoyin kwanciya daban-daban.

Za a iya ƙididdige nauyin nauyin layin na yanzu ta hanyar dabara mai zuwa:

Da'irar juriya mai tsafta guda ɗaya: I=P/U

Da'ira guda-ɗaya tare da inductance: I=P/Ucosφ

Da'irar juriya mai tsafta ta uku: I = P/√3UL

Da'irar matakai uku tare da inductance: I = P/√3ULcosφ

Ma'anar ma'anoni a cikin ma'auni na sama sune:

P: shine ikon kaya, a watts (W);

UL: shine ƙarfin lantarki na samar da wutar lantarki mai matakai uku, a cikin volts (V);

cosφ: shine ikon factor.

Lokacin zabar bisa ga ikon ɗaukar halin yanzu na waya, ƙa'ida ta gabaɗaya ita ce ƙarfin ɗaukar halin da ake ba da izini bai gaza ƙididdige halin yanzu na haɗin layin ba.
