1.1 Bayanin Aikin

500 kVAuku fase kushin saka transformerAn isar da shi zuwa Amurka a cikin 2025. Ƙarfin wutar lantarki na wutar lantarki shine 500 kVA tare da sanyaya KNAN. Babban ƙarfin lantarki shine 34.5GrdY / 19.92 kV tare da ± 2 * 2.5% tapping range (NLTC), ƙananan ƙarfin lantarki shine 0.48 kV, sun kafa ƙungiyar vector na YNd1.

Wannan 500kVA guda uku -saitin kushin{2}} wanda aka ɗora shi an kera shi musamman don aikace-aikacen rarrabawa a waje a Arewacin Amurka da sauran kasuwanni masu buƙata. Yana ba da ƙaƙƙarfan sawun ƙafa da amintaccen matsakaicin-ƙarfin wutar lantarki zuwa canjin wutar lantarki mai ƙarancin ƙarfi, yana mai da shi kyakkyawan zaɓi don rukunin kasuwanci, wuraren shakatawa na masana'antu, rukunin gidaje, da hanyoyin sadarwar jama'a.

Babban ƙirar lantarki tare da ƙungiyar vector YNd1.
Kushin wutar lantarki mai amfani yana ɗaukar ƙungiyar vector YNd1, tare da haɗe-haɗe da tauraro mai girman ƙarfin lantarki da kuma keɓaɓɓen da aka fito da shi (H0). Wannan saitin yana ba da zaɓuɓɓukan tsarin ƙasa masu sassauƙa. Haɗin low-voltage delta yana haifar da rufaffiyar hanya don magudanar ruwa-jeri-sifili, yadda ya kamata yana murkushe masu jituwa tare da haɓaka ƙarfin injin na'ura don ɗaukar kaya marasa daidaituwa. An haɗa fis ɗin Cooper masu inganci a gefe na farko, suna ba da ingantaccen kariyar wuce gona da iri ta hanyar ware kurakurai cikin sauri.

Tsarin insulating da sanyaya mai dacewa da muhalli (KNAN / FR3).
Hanyar sanyaya shine KNAN (convection na halitta ta amfani da ruwa mara ƙonewa). Na'urar taswira tana cike da ruwan ester na halitta na FR3 - mai sabuntawa, dielectric mai lalacewa da aka samu daga mai. FR3 yana da madaidaicin walƙiya sama da digiri 300, yana haɓaka amincin wuta sosai idan aka kwatanta da mai na ma'adinai na al'ada. Matsayinsa mai kyau na danshi (425 ppm jikewa a -20 digiri vs. kawai ~ 8 ppm don man ma'adinai) yana rage haɗarin rashin lalacewa. Bugu da ƙari, FR3 yana ba da damar yin aiki mai girma har zuwa 20% mafi girma ba tare da sadaukar da rayuwa ko aminci ba. An tabbatar da mafi girman ƙarfinsa na dielectric da juriyar tsufa a cikin miliyoyin na'urorin rarrabawa a duniya.

Yarda da ƙa'idodin ingancin DOE.
Na'urar taswira ta cika daidai da sabbin buƙatun ingancin Ma'aikatar Makamashi ta Amurka (DOE). Ana sarrafa asarar da ke ƙarƙashin ƙayyadaddun yanayin kaya zuwa matakin jagorancin masana'antu, yana taimaka wa abokan ciniki cimma tanadin makamashi da rage fitar da iskar carbon.

Tare da ƙirar wutar lantarki ta ci gaba, eco-friendly da wuta mai aminci FR3 ruwa, fuses Cooper mai inganci, da tsananin yarda da ƙa'idodin ingancin DOE, wannan mai ɗaukar kushin 500kVA shine amintaccen bayani don ayyukan rarraba wutar lantarki da yawa.
