Nā ʻāpana heʻe metala no nā mea haki kaapuni

ʻO ka poʻe ma luna o 3kV ka mea maʻamau i kapa ʻia nā mea hana uila kiʻekiʻe.Hiki ke hoʻohana ʻia nā mea haki kaapuni no ka puʻunaue ʻana i ka ikehu uila, hoʻomaka pinepine i nā motika asynchronous, pale i nā laina mana a me nā kaʻa, a ʻoki ʻoki i ke kaapuni inā loaʻa iā lākou nā hewa koʻikoʻi e like me ka overload a pōkole pōkole a undervoltage.Ua like kāna hana me ka hui pū ʻana o ka fuse switch a me ka overheated relay.A ʻo ka mea maʻamau, ʻaʻohe pono e hoʻololi i nā ʻāpana ma hope o ka haki ʻana i ka manawa hewa.Ua hoʻohana nui ʻia.He loulou koʻikoʻi loa ka hāʻawi ʻana i ka mana i ka hana, hoʻoili a hoʻohana ʻana i ka uila.

Loaʻa ka ʻōnaehana hoʻolaha i nā mea hoʻololi a me nā ʻano mea uila kiʻekiʻe a haʻahaʻa haʻahaʻa, ʻo ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa kahi ākea o nā mea uila.Hoʻohana nui ʻia nā ʻāpana stamping metala i nā mea haʻihaʻi kaapuni, e like me ka ʻauamo magnetic, ka neʻe ʻana i ka pilina, ka pā hoʻopili, ka junction board, bracket, arc plate a pēlā aku.Hiki iā SOOT ke hana i nā huahana e hoʻokō i nā pono o ka mea kūʻai aku.Koho mākou i nā mea waiwai kiʻekiʻe e hana i nā huahana, ʻoi aku ka paʻakikī o nā huahana, kūpaʻa ikaika i ka corrosion a ʻaʻole maʻalahi i ka pala.Hoʻohana nui ʻia nā mea haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i nā ʻōnaehana hāʻawi haʻahaʻa haʻahaʻa, ka mana mana o nā ʻano mea hana mechanical āpau a me ka hoʻomalu a me ka pale ʻana i nā pauku uila.Hiki ke hoʻokaʻawale ʻia nā mea haʻahaʻa haʻahaʻa haʻahaʻa i nā ʻano like ʻole, e like me ACB air circuit breaker, MCCB mold case circuit, MCB miniture circuit breaker, RCD.
