ʻIke paha ʻoe i ke kumu o ka leakage o ke kaʻa uila i nā puʻu?

Kaʻa uila e hoʻouka anaHoʻokaʻawale ʻia ka pile leakage i ʻehā mau ʻano, ʻo ia hoʻi: semiconductor component leakage current, power leakage current, capacitor leakage current and filter leakage current.

1. Leakage o kēia manawa o nā mea semiconductor

ʻO ke au liʻiliʻi loa e kahe ana ma ka hui PN ke ʻoki ʻia.ʻO ka DS i mua ke alo, ʻo GS ka hoʻohuli ʻana, a ma hope o ka wehe ʻia ʻana o ke kahawai conductive, e kahe ka mana mai D a i S. Akā ʻo ka ʻoiaʻiʻo, ma muli o ke ola ʻana o nā electrons manuahi, hoʻopili ʻia nā electrons manuahi i SIO2 a me N+, e hopena i ka leakage. ke au o DS.

2. Mana leakage au

I mea e hōʻemi ai i ka hoʻopili ʻana i ka mana hoʻololi, e like me ke kūlana aupuni, pono e hāʻawi ʻia kahi kānana kānana EMI.Ma muli o ka pilina o ke kaʻapuni EMI, aia kahi manawa liʻiliʻi i ka honua ma hope o ka hoʻopili ʻana o ka mana hoʻololi i nā kumu, ʻo ia ka leakage current.Inā ʻaʻole i hoʻopaʻa ʻia, e loaʻa ana i ka pūpū o ka lolouila ka volts o 110 volts i ka honua, a e ʻeha ʻo ia ke hoʻopā ʻoe iā ia me kou mau lima, a pili pū ia i ka hana a ke kamepiula.

3. Capacitor leakage au

ʻAʻole hiki i ka capacitor medium ke non-conductive;i ka wā e hoʻohana ʻia ai kahi voli DC i ka capacitor, e loaʻa i ka capacitor kahi leakage au.Inā ʻoi aku ka nui o ka leakage, e pōʻino ka capacitor i ka wela.Ma waho aʻe o nā capacitors electrolytic, he liʻiliʻi loa ka leakage o nā capacitors ʻē aʻe, no laila ua hoʻohana ʻia ke ʻano kūʻokoʻa insulation e hōʻike i kā lākou hana insulation, aʻo nā capacitor electrolytic he nui leakage o kēia manawa, no laila ua hoʻohana ʻia ka leakage e hōʻike i kā lākou hana insulation (proportional). i ka hiki).Ke hoʻohana ʻia ka volta hana DC i hoʻopaʻa ʻia i ka capacitor, e ʻike ʻia ka hoʻololi ʻana o ka hoʻouka ʻana i kēia manawa e hoʻomaka i ka nui, a emi iho me ka manawa.Ke hiki i kekahi waiwai hope, hiki i kahi kūlana paʻa.Ua kapa ʻia kēia au waiwai hope.i=kcu(ua);ma kahi o k ke au mau leakage, he μa (v:μf) ka wae.

4. Kānana leakage i kēia manawa

ʻO ke au o ka leakage o ka kānana mana i wehewehe ʻia e like me: ka manawa mai ka hale kānana a hiki i kēlā me kēia hopena o ka laina komo AC ma lalo o ka volta AC i helu ʻia.Inā hoʻokaʻawale loa ʻia nā awa a pau o ka kānana mai ka hale, ʻo ka waiwai o ka leakage o kēia manawa e hilinaʻi nui ʻia i ka leakage o ka capacitor mode maʻamau CY, ʻo ia hoʻi, hilinaʻi nui ia i ka hiki o CY.Ma muli o ka nui o ka leakage o ka kānana, e pili ana i ka palekana pilikino, loaʻa i nā ʻāina āpau o ka honua nā kūlana koʻikoʻi no ia.No ka lako mana 220V/50Hz AC, ʻo ka leakage o ka kānana walaʻau e koi ʻia ma lalo o 1mA.
