I ka pane ʻana i ka noi a me ka hoʻomohala ʻana o nā noi ʻenehana hou i ke kaʻaahi kaʻaahi, ua noʻonoʻo nā mea nona nā kaiāulu Kina pehea e hana ai i kahi ala hou o ka hana naʻauao a me ka mālama ʻana i ke kaʻa kaʻa e hōʻoia i ka palekana, ʻōmaʻomaʻo, hilinaʻi, kiʻekiʻe, a haʻahaʻa. -koki hana o ke kaʻa lehulehu kūlanakauhale.
Uila kiʻekiʻe-wikiwiki kaʻaahi kaʻaahi: hoopau i ka uila ikehu o ka mana lako nenoaiu, hoohuli i ka uila ikehu i mechanical kinetic ikehu, a malama i ka offset.Hāʻawi ka ʻōnaehana uila uila i ka mana no nā kukui like ʻole, escalators, blowers, pumps a me nā lako mīkini mana ʻē aʻe i nā kikowaena a me nā ʻāpana, a me ka mana no ke kamaʻilio, hōʻailona, automation a me nā mea hana ʻē aʻe.ʻO ka hāʻawi mana hoʻololi o ka ʻōnaehana kukui uila e pili ana i ke keena hoʻohaʻahaʻa hoʻohaʻahaʻa koko a me nā kukui kukui uila a me nā lako hāʻawi kukui.
Hōʻike ʻia ka ʻōnaehana lako mana i wehewehe ʻia mai ka hiʻohiʻona o ka lumi o loko, kahi i loaʻa ai nā lako lako mana he nui ma lalo o kēlā me kēia kikowaena hoʻolaha.Hiki i ka AC a me DC ke hoʻokaʻawale i nā lako lako mana i ka ʻōnaehana AC a me ka ʻōnaehana DC.
ʻO nā Harmonics i ke kaʻa kaʻa kaʻa kaʻa nui mai ka traction belt power supply rectifier inverter unit, a ukali ʻia e kahi pūʻulu piha o nā mana lako DC, kukui, elevators, monitors, air conditioners, drainage pipes a me nā mea hana ʻē aʻe.ʻO nā harmonics kī ka 5th, 7th, 11th a me 13th harmonics, me kekahi mau harmonics 3rd pū kekahi.ʻO ka mālama pono ʻole i ka ʻōnaehana hoʻohana harmonic kiʻekiʻe e hoʻonui i ka nalowale o ka laina, pili i ka hana hilinaʻi o ka pale relay a me nā mea hoʻokele aunoa, a hōʻemi i ka palekana o ka hana o nā lako uila i hoʻohana ʻia, a laila e hoʻoulu ai i ka interference electromagnetic i nā kamaʻilio a me nā hōʻailona.Hiki i nā Harmonics ke loaʻa i ka hopena pōʻino i nā mea hana uku mana reactive ma ka laina.I ka manawa like, e hoʻonui ka mea hoʻihoʻi mana reactive i nā harmonics, e hana i kahi pōʻai ʻino.
Waiwai Mea hoʻohana o ke Aupuni Harmonic
ʻO ke kaʻaahi kūlanakauhale, ʻo ia hoʻi ka mana lako a me ka ʻōnaehana hoʻolaha o nā kahua kaʻaahi, pono i ka hilinaʻi paʻa loa.ʻO ka manawa Pulse ke kumu nui o ka hoʻoweliweli i ka hilinaʻi o kāna lako mana.Hiki i ka hoʻohana ʻana i nā kānana ikaika ke hoʻomalu pono i nā harmonics, e hōʻemi i ka pōʻino o nā harmonics i ka lako mana a me nā ʻōnaehana hoʻoili, a e hōʻoia i ka hana palekana a paʻa o ke kaʻaahi kūlanakauhale.I ka manawa like, ma hope o ka kānana harmonic, ua hoʻemi ʻia ka nalowale o ka harmonic o ka ʻōnaehana, a hiki ke hoʻohana maʻamau ka mea hoʻoponopono capacitor mua, e hōʻemi hou ana i ka nalowale o ka ʻōnaehana.
Nā pilikia āu e hālāwai ai?
1. He haʻahaʻa ke kumu mana, a ʻaʻole hiki ke hoʻokomo ʻia ka mea hana kuʻuna reactive mana uku i ka hana a i ʻole e pōʻino pinepine ʻia;
2. Hoʻololi hoʻouka
3. ʻO ke kiʻekiʻe fluctuation rate o harmonic current pili i ka hana hilinaʻi o ka pale relay a me nā lako ʻōnaehana hoʻokele aunoa;
4. He koʻikoʻi ka ʻokoʻa ʻekolu o ka Pūnaewele ma ka ʻōnaehana mana.
ʻO kā mākou hoʻonā:
1. I mea e hōʻemi ai i ka ʻike o nā harmonics kiʻekiʻe, ua hoʻokomo ʻia kahi mea kānana kumu ma ke kaʻa kaʻa lua 400V o ka substation iho no ka kānana.
2. Hoʻohana i ke ʻano ikaika o Hongyan series dynamic reactive power generators e hāʻawi i ka mana reactive i kēlā me kēia māhele o ka ʻōnaehana a mālama i nā harmonics o ka ʻōnaehana i ka manawa like
3. E koho i nā lako hana uku palekana Hongyan, e hoʻolālā maikaʻi i ka capacitor a me nā ʻāpana reactor series e like me ke kūlana pulse o kēia manawa o ka ʻōnaehana, hoʻomaikaʻi i ke kumu mana ma o ka uku mana reactive, a hoʻomaikaʻi i ka maikaʻi o ka mana o ke kaʻa kaʻa kaʻa a me ka ʻōnaehana hoʻolaha.
4. Hoʻohana ka Hongyan i ka hoʻopaʻi ʻana i ke ʻano o ka hoʻokaʻawale ʻana i ʻekolu manawa a me ka uku hoʻokaʻawale ʻekolu, a noʻonoʻo i nā koi uku o ka ʻekolu-phase unbalance o ka polokalamu ʻōnaehana.
