ʻO nā hopena nui o ka harmonics

Hōʻike pinepine ʻia nā Harmonics i ko mākou ola i kēlā me kēia lā.ʻOi aku ka nui o ka loaʻa ʻana o kahi kiʻekiʻe o nā harmonics maʻamau i nā halemai, nā kulanui, nā kikowaena aupuni, nā hale kūʻai, nā hale hana, nā ʻoihana kaumaha, radio, TV, hoʻolaha, ʻoihana meaʻai, hōkele a me ka casino, ʻoihana ʻenehana nui, nā mea kanu mālama wai. ʻO nā mea hana hana harmonic maʻamau e like me: hoʻololi i nā lako mana, welders, Ups, ka mea hoʻololi alapine kahiko me ka ʻenehana hoʻololi mana thyristor, nā kaʻa kaʻa, nā mea hoʻololi me nā mea hoʻoponopono hoʻomalu, DC mana no nā pahu DC, Induction umu.
ʻO nā hopena nui o ka harmonics e like me lalo:
1.Overheating a me nā haʻalulu me kaʻelemakule mua o nā'āpana a pau, me nā hopena pōkole a me ka manawa maʻamau i ka manaʻolana o ke ola.
2.Faults ma nā lako uila uila.
3. Poino i na mea pa'i kaapuni papa.
4.Electric motor overload.
5.Premature elemakule capacitors a me ka poino ma muli o ka resonance.
6.Power kumu ho'ēmi.
7.Overload o ka uea kūʻole.
8. Electromagnetic mana.
9.Measurement hewa ma ka ikehu mika.
10.MCCB a me contactor keakea hewa.
11. Incorrect tripping o ka hoololi.
Nā kānana harmonic activeʻO nā mea hana maikaʻi o ka ikehu e hoʻolako ikaika ana i kahi au i hoʻopaʻa ʻia me ka amplitude like me ke au harmonic, kahi i hoʻokomo ʻia e kūʻē i nā harmonics ma ka pūnaewele.E hoʻopau kēia i ke au harmonic i ka ʻōnaehana uila.ʻO ka hopena, ʻo ka mea i hoʻolako ʻia e ke kumu mana e noho sinusoidal no ka mea e hoʻopau nā harmonics kekahi i kekahi a e hoʻemi ʻia ka distortion harmonic i haʻahaʻa loa.
Nā kānana hanahiki ke hoʻokomo i nā wahi āpau ma kahi pūnaewele a hāʻawi i nā hiʻohiʻona he nui:
1. Eliminate i nā au harmonic a pau a hiki i ka 50th kauoha mai nā ukana laina ʻole.
2. E hoʻopaʻa i ka mana reactive a hoʻoponopono i ke kumu mana.
3. E uku no ka flicker ma muli o ka mana reactive.
Noker Uilakānana mana hanahoʻohana i ka ʻenehana ʻekolu pae kiʻekiʻe loa, me nā hiʻohiʻona o ka liʻiliʻi liʻiliʻi, ka mana kiʻekiʻe, ka paʻa a me ka hana hilinaʻi, ka mea i makemake ʻia e nā mea kūʻai aku. ka uku, ke alapine harmonic mai 3 a 50 harmonic, hiki ke hoʻonui i ka hoʻonui ʻana i ka maikaʻi o kāu grid.
