I kēia manawa, ʻoi aku ka paʻakikī o nā ʻoihana lako mana i ka maikaʻi o ka mana.ʻO ka loiloi hoʻohana mana no ka hoʻonui ʻana i ka ʻoihana a i ʻole ke kūkulu ʻana i nā papahana hou ʻaʻole ia e pili ana inā he ʻepekema a kūpono hoʻi ka mana ʻōnaehana mana a me ka hoʻonohonoho mana.Hoʻopuka ka hopena o ka ʻōnaehana mana i nā koi loiloi hou aʻe.I mea e kōkua ai i nā ʻoihana e hoʻopōmaikaʻi i ka noi no nā papahana hou, hāʻawi ka Power Quality Division o Zhejiang Hongyan Electric Co., Ltd. i nā lawelawe loiloi mana a me nā lawelawe loiloi no nā papahana hou, e komo pū ana me nā laina transit kaʻa nui, E hana i ka loiloi maikaʻi o ka mana. a me ka nānā ʻana i nā kahua kaʻa kaʻaahi, nā papahana umu ahi uila, nā kumu hana ʻoihana nui, ka hoʻolaha ʻana i ka mana o ka paka ma mua o ka hoʻolālā ʻana, nā hale hale kalepa, a me nā mea ʻē aʻe. papahana ma kahi o ka kali ʻana a hiki i ka maikaʻi o ka mana Ma hope o ka hōʻike ʻia ʻana o ka pilikia a loaʻa ka hopena nui, lawe ʻia nā hana hoʻoponopono.
ʻO ka loiloi o ka mana maikaʻi e pili ana i ka loiloi o nā hōʻailona o ka mana e like me harmonics, voltage fluctuations and flicker, power factor, and three-phase unbalance ma ka hoʻohālikelike ʻana, ka nānā ʻana, a me ka helu ʻana i ka hopena o nā ukana mana i ka ʻōnaehana mana o ka mea hoʻohana ma ka ʻōnaehana maʻamau. wahi pili., Hiki ke hoʻopukaʻia ka hōʻike loiloi i loko o 10 mau lā hana inā pau nā mea.
Ka Papa Hana Hoʻonaʻauao Kūlana Mana Mana
Maʻiʻo loiloi:
E hoʻohālikelike, e kālailai, a e helu i ka hopena o ka haʻawe mana i loko o ka ʻōnaehana mana o ka mea hoʻohana ma nā wahi pili maʻamau o ka ʻōnaehana, me nā mea hōʻailona o ka mana e like me ka harmonics, nā loli uila a me ka flicker, ka helu mana, a me nā pae ʻekolu.
Ke kumu o ka helu mana
Nā kūlana kūpono o kā mākou hui
ʻO ke kumu loiloi no ka maikaʻi o ka mana i ka nānā ʻana a me ke kaʻina helu e hoʻokō i nā kūlana e pili ana i ka mana maikaʻi o kā mākou hui a me ka ʻoihana mana, me:
