Hoʻopilikino kiʻekiʻe-voltage switchgear GGD

Nānā nui

ʻO ke ʻano GGD ʻano AC haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa keena hoʻokaʻawale kūpono no nā ʻōnaehana hoʻoili mana me AC 50Hz, helu ʻia ka volta hana o 380V, a helu ʻia ka hana o kēia manawa o 5000A no nā mea hoʻohana mana, e like me nā mea kanu mana, substations, ʻoihana a me nā ʻoihana mining, e like me ka hoʻololi ʻana i ka mana. , kukui a me nā lako hāʻawi mana.no ka puunaue a me ka hoomalu ana.
Loaʻa i ka huahana nā hiʻohiʻona o ka mana haʻihaʻi kiʻekiʻe, ke kūpaʻa maikaʻi a me ka wela, ka hoʻolālā uila maʻalahi, ka hui kūpono, ka hana ikaika, ka hana hou a me ka pae pale kiʻekiʻe.Hiki ke hoʻohana ʻia ma ke ʻano he huahana pani no ka switchgear haʻahaʻa haʻahaʻa.
ʻO GGD ʻano AC haʻahaʻa haʻahaʻa haʻahaʻa puʻupuʻu puʻupuʻu e hoʻokō me IEC439 "Low-voltage switchgear and control equipment", GB7251 "Low-voltage switchgear" a me nā kūlana ʻē aʻe.

Ke Ana Hoʻohālike

Nā hana a me nā hiʻohiʻona

◆ʻAʻole pono ke kiʻekiʻe o ka ea ambient ma mua o +40 ℃ a ʻaʻole i lalo ma lalo o -5 ℃.ʻAʻole ʻoi aku ke kiʻekiʻe o ka mahana ma waena o 24h ma mua o +35 ℃.
◆ ʻO ka hoʻokomo ʻana a me ka hoʻohana ʻana i loko, ʻaʻole ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe o kahi e hoʻohana ai i 2000m.
◆ʻAʻole ʻoi aku ka haʻahaʻa haʻahaʻa o ka ea a puni i ka 50% i ka wā o ka wela kiʻekiʻe he +40 ℃, a ʻae ʻia kahi haʻahaʻa pili nui i ka wā e haʻahaʻa ai ka mahana.(e laʻa, 90% ma +20°C) Pono e noʻonoʻo ʻia ka hopena o ka condensation i hiki mai i kekahi manawa ma muli o nā loli wela.
◆Ke hoʻokomo ʻia nā mea hana, ʻaʻole pono ka makemake o ka mokulele kū i ka 5%.
◆ Pono e hoʻokomo ʻia nā mea hana ma kahi me ka haʻalulu nui ʻole a me ka haʻalulu, a me kahi i lawa ʻole e hoʻopōʻino i nā mea uila.
◆Ke loaʻa i nā mea hoʻohana nā koi kūikawā, e kūkākūkā me ka mea hana.
