HP-MVnex: Ukuqaphela kwi Switchgear ephakeme phakeme

Ukudizaynwa nokungeniswa kwezimali kwezimali ye-HPMVnex

Izinto Ezinhloko kanye nezimo zokudizayna kwezimali ze-HPMVnex

I-HPMVnex leswitchgear yemetal ephakathi yesokhwe yemidla enemodiwele yenkqubo enenhlukanenhlukwano yamaceli, izinhlobo nezinhlobo. Lokhu kusiza ukulungisa izindleko bese kuhlinza ukusebenza ngendlela elula noma xa kunezinkinga. Isakhiwo esihlinzekile sibalulekile ukuthi izicathami zokwenza zingaphambene ngeke zingathatha konke okunye. Akuyona kuphela ukuthi thewalela - amamelwano okwamanje emasistemeni we-38kV uyisusa ukuthi lokhu kusebenza ngempumelelo. Ngokwesibonelo sokuphathwa, lokhu kwenza ukuthi izinto zibe lelekile ukulawulwa. Ngaphezulu kwalokho, kuthatha fela izindleko eziphakeme zokuthi siyakuthanda ukuzivikelela. Izifekelo zokwenza ezisetshenzisa amandla apheleleyo kuzothola ukuthi lezi ziqiniso zibaluleke ngokudla ngokudla.

I-Metal-Enclosed vs. Metal-Clad Construction: Imfananisiso, Imingcele, Nezinhloso

Kunelithi yokulingana nezinhlelo zokugcina eziyinhloko, izinhlelo zokugcina izinhloko zinikeza ukuphela okuningi ngokuthi kuzinzile amandla okugcina kanye nezilungiselelo eziphumelelayo kuzo zokugcina izinto eziphumelelayo. Lezi zinhlelo zivumelana nezimiso ezaqophelelweyo ze-ANSI/IEEE C37.20.2-2025 ngokuphezulu kwe-arc, okwenza kube lula kakhulu ezingeni lapho amandla esiyakhona engqondweni. Sibona lezi zinhlelo zisetshenziswa khona kakhulu ezingeni zokugcina amandla nezindawo zokusebenza, lapho kuthintwa ukuthi kungakhona amandla aphansi. Ngokwesicatipho sika-Electrical Safety Quarterly esithole ngenkulungwane yesikole, izindawo ezisetshenzisa leli thonakalitha zinezinto eziphansiwe nge-37% lapho kuzovala amandla ngaphakathi ngisho nake kuzothintwa ukuthi kungakhona ukwehla kwezinye izinto ngaphandle kweqile.
