A question about functional insulation requirements at the ends of a current fuse

The following circuit diagram The current fuse in position F1 is usually connected in series with the line.The photos of the real thing are shown in the following two pictures, the left one is not labeled, the right one shows the location of the current fuse and some other basic information. In the diagram above,…

Isigaba sesi-3 – Iqondwa kanjani incazelo ye-“voltage yokusebenza”

i-votlage yokusebenza: I-voltage ephezulu lapho ingxenye ecatshangelwayo ingaphansi kwayo lapho into esetshenziswayo ihlinzekwa nge-voltage yayo elinganiselwe futhi isebenza ngaphansi kokusebenza okujwayelekile, enezilawuli kanye nemishini yokushintsha ebekwe ukuze kukhuliswe inani QAPHELA 1 Amandla kagesi asebenzayo acabangela ama-resonant voltages. QAPHELA 2 Lapho wehliswa i-voltage esebenzayo, umthelela wama-voltages wesikhashana uyazitshwa. The rated voltage imvamisa ivolumu yokulethwa kwesampula evivinywayo,…

Ithebula 17 kanye neThebula 18 le-IEC 60335-1

Kukhona inothi kuthebula 17 kanye nethebula 18 njengokuthi “Kuma-voltage okusebenza kanye ne-gt; 10 V kanye ≤ 630 V, uma i-voltage ingacaciswanga kuthebula, amanani amabanga ahamba phambili angatholwa ngokufaka phakathi.”. Uma i-voltage yokusebenza ingelona inani elisohlwini lwetafula, ngakho-ke ngokuvamile sidinga ukubala ukuze sithole inani elilinganiselwe, ukuze kube lula, ngilungise ithebula le-excel, abahloli bangabuza ngokuqondile ithebula ukuze…
