Tabbatarwa Ƙarƙashin Damuwa: Gwajin Ƙarfin Ƙarfin Ƙarƙashin Ƙarfafa Fuse Cutout
Gabatarwa: Lokacin Kariyar Grid
A matsakaici irin ƙarfin lantarki rarraba cibiyoyin sadarwa (10kV zuwa 35kV), da Dropout Fuse Cutout shine babban mai kare tafsiri da layukan gefe. Dole ne ya yi abubuwa biyu ba tare da aibu ba: busa lokacin da kuskure ya faru kuma, da mahimmanci, kashe babban baka na wutar lantarki.
Wannan labarin yana nazarin mahimmancin Gwajin Ƙarfin Katsewa (wanda kuma aka sani da gwajin ɓarkewar ɗan gajeren lokaci), gwajin da DGG Power ke yi ba tare da gajiyawa ba don tabbatar da amincin grid na duniya.
Menene Ƙarfin Katsewa?
Ƙarfin katsewa (ko karyewar ƙarfin) yana nufin matsakaicin kuskuren halin yanzu wanda fis zai iya katse shi cikin aminci ba tare da gazawar bala'i ba-kamar fashewar insulator ko bututun fitarwa.
Hoton da ke sama yana nuna a Matsakaicin Voltage Fuse ya yi nasarar share kuskure, wanda ke ɗauke da jet na hayaki da tururin ƙarfe da aka kora zuwa ƙasa, wanda shine aikin sa hannun fis ɗin korar..
Cikakken Injiniyan Gwajin
Gwajin (wanda aka gudanar bisa ga IEC 60282-2 ko ANSI C37.41) yana mai da hankali kan mahimman abubuwa guda uku:
Amperage Short-Circuit (kA): Fus ɗin yana ƙarƙashin manyan igiyoyin simmetric da asymmetrical (misali, 8kA, 10kA, 12.5kA ko mafi girma, dangane da ajin ƙarfin lantarki).
Voltage na Farko na wucin gadi (TRV): Wannan shine matsananciyar ƙarfin wutar lantarki wanda a duk faɗin fis ɗin yana hulɗa da miliyon seconds bayan an kashe baka. Ƙirar mu tana tabbatar da rata ta sake ƙarfafa rufinta da sauri fiye da tashin TRV.
Aikin 'Drop-out': Dole ne haɗin haɗin injin yayi aiki lokaci guda zuwa katsewa, yana tabbatar da tazarar iska mai ganuwa don aminci.
Fa'idar Fasaha ta DGG Power: Ingantaccen Ƙarshen Arc
DGG Power's fuse cutouts suna amfani da tsafta mai tsayi Arc-Extinguishing Tube liner. Ƙarƙashin matsanancin zafin jiki na baka, wannan layin yana bazuwa kuma yana fitar da iskar gas mai ƙarfi na de-ionizing. Wannan iskar gas, kamar yadda aka gani ana fitar da shi a hoton gwajin, da sauri ya yi sanyi ya kuma kawar da baka, ya tilasta masa ya mutu a sifiri na gaba. Wannan ingantaccen ƙarfin yana da mahimmanci ga grid, inda ake buƙatar kariyar kuskure mai ƙarfi saboda faɗaɗa nauyin masana'antu.
