Nānā Huahana

ʻO YEM3D-250 DC circuit breakers ka mea i hoʻohana nui ʻia i nā ʻōnaehana DC me ka helu insulation voltage o 1600V, helu ʻia ka volta hana o DC 1500V a ma lalo, ma luna o ka ukana a me ka pōkole pōkole pale ʻana i ka hoʻoili mana a me nā laina pale a me nā lako lako mana i nā ʻōnaehana DC me ka helu o kēia manawa. 250A a lalo.

Kūlana hana

1. Ka wela wela -5℃~+40℃.
2. Ke kahua hoʻokomo o ke kiʻekiʻe ʻaʻole ʻoi aku ma mua o 2000m.
3. ʻAʻole ʻoi aku ka haʻahaʻa haʻahaʻa o ka ea ma ke kahua hoʻonohonoho ʻana ma mua o 50% ma kahi wela kiʻekiʻe o + 40 ℃ a ʻoi aku ke kiʻekiʻe o ka haʻahaʻa haʻahaʻa, no ka laʻana 90% ma 20 ℃. Pono e lawe ʻia nā hana kūikawā no ka condensation i kekahi manawa. ma muli o ka hoʻololi ʻana o ka mahana.
4. He 3 ka pae haumia.
5. Kaapuni kaapuni kaapuni nui hoʻonoho waeʻano Ⅲ, ke koena auxiliary kaapuni, cintril kaapuni hoonoho waeʻano Ⅱ.
6. Kaapuni kaapuni enemi electromagnetic kaiapuni A.
7. Pono e hoʻokomo i nā mea haʻihaʻi kaapuni i ka loaʻa ʻole o ka lepo pahū a me ka lepo ʻole, lawa e hoʻopōʻino i ka metala a hōʻino i ka insulation.
8. Pono e hoʻokomo ʻia nā mea haki kaapuni me ka ʻole o ka ua a me ka hau.
9. Nā kūlana mālama:ʻo ka mahana wela o ka ea -40 ℃ ~ + 70 ℃.
