GCS kiʻekiʻe a me ka haʻahaʻa kaila huki ʻana i waho

Nānā nui

He kūpono ka GCS low-voltage withdrawable switchgear no nā ʻōnaehana hoʻoili mana i nā mea kanu mana, ʻaila, kemika, metallurgy, textile, nā hale kiʻekiʻe a me nā ʻoihana ʻē aʻe.I loko o nā mea kanu mana nui, nā ʻōnaehana petrochemical a me nā wahi ʻē aʻe me kahi kiʻekiʻe o ka automation a me ka koi ʻana i ka interface me nā kamepiula, hiki ke hoʻohana ʻia ma ke ʻano he mana mana a me ka ʻōnaehana lako mana me kahi alapine AC ʻekolu-phase o 50 (60) Hz, kahi helu. Volta hana o 400V, 660V, a me ka helu o kēia manawa o 5000A a ma lalo.ʻO kahi hoʻonohonoho piha haʻahaʻa haʻahaʻa o nā mea hoʻoili mana i hoʻohana ʻia i ka hāʻawi ʻana i ka mana, ka hoʻokele kikowaena kaʻa, a me ka uku mana reactive.Hoʻopili ka hoʻolālā ʻana o ka hāmeʻa i kēia mau kūlana: IEC439-1 "Low-voltage switchgear and control equipment" GB7251 "Low-voltage switchgear".

Ke Ana Hoʻohālike

Kaiapuni hoʻohana maʻamau

◆ʻAʻole pono ke kiʻekiʻe o ka ea ambient ma mua o +40 ℃, ʻaʻole i emi iho ma mua o -5 ℃, a ʻo ka awelika wela i loko o 24 mau hola ʻaʻole pono e kiʻekiʻe ma mua o +35 ℃.Ke ʻoi aku ka nui, e hana ʻia ka hana derating e like me ke kūlana maoli;
◆No ka hoʻohana ʻana i loko, ʻaʻole ʻoi aku ke kiʻekiʻe o ke kiʻekiʻe o kahi e hoʻohana ai ma mua o 2000m;
◆ʻAʻole ʻoi aku ka haʻahaʻa haʻahaʻa o ka ea a puni i ka 50% i ka wā o ka wela kiʻekiʻe he +40 ° C, a ʻae ʻia kahi haʻahaʻa haʻahaʻa haʻahaʻa, e like me 90% ma +20 ° C.hana i nā hopena condensation;
◆Ke hoʻokomo ʻia ka mea hana, ʻaʻole pono ke ʻano o ka mokulele kūpaʻa ma mua o 5 °, a ʻo ka hui holoʻokoʻa o nā keʻena keʻokeʻo e palahalaha (e like me ke kūlana GBJ232-82);
◆ Pono e hoʻokomo ʻia ka mea hana ma kahi me ka haʻalulu nui ʻole a me ka haʻalulu a ʻaʻole lawa i mea e ʻino ai nā ʻāpana uila;
◆Ke loaʻa i nā mea hoʻohana nā koi kūikawā, hiki iā lākou ke kūkākūkā me ka mea hana.
