ʻO ka Leakage Current e pili ana i ke au i hana ʻia ma o ka ʻaoʻao hoʻopuni a i ʻole ka insulating i waena o nā ʻāpana metala i hoʻokaʻawale ʻia mai kekahi i kekahi, a i ʻole ma waena o nā ʻāpana ola a me nā ʻāpana i hoʻopaʻa ʻia, inā ʻaʻohe hemahema o ka hoʻohana ʻana i ka voltag.Ma ka US UL Standard, Leakage Current ʻO ia ka mea hiki ke hoʻokō ʻia mai ka ʻāpana hiki ke loaʻa i nā lako hale me ka Capacitive Coupling Current.ʻElua mau ʻāpana o ka Leakage, ʻo ia ka Conduction Current I1 ma o ka Insulation Resistance;ʻO ka hoʻoneʻe ʻana ma o ka mana puʻupuʻu ʻo ka I2 o kēia manawa, ʻo ka capacitive reactance o ka hope ʻo XC=1/2pfc ka hoʻohālikelike ʻana i ke alapine o ka mana, a me ka piʻi ʻana o ka mana i hāʻawi ʻia me ka piʻi ʻana o ke alapine, no laila ka leakage. Hoʻonui ʻia me ka piʻi ʻana o ka mana pinepine.No ka laʻana: Ke hoʻohana nei i kahi Thyristor no ka hoʻolako ʻana i ka mana, ʻo kona Harmonic ke kaumaha o ka hawewe e hoʻonui i ka leakage.
Inā ʻike ka mea hoʻāʻo leakage o kēia manawa i ka hana hoʻokaʻawale o kahi kaapuni a i ʻole kahi ʻōnaehana, i kēia manawa ke komo i nā mea a pau e hele ana ma o ka mea hoʻolalelale.
Ma waho aʻe o ke kahe ʻana o kēia manawa i ka honua (a i ʻole ka ʻāpana hoʻokele ma waho o ke kaapuni), pono ia e hoʻokomo pū i ka kahe o kēia manawa i ka honua ma o nā mea hana Capacitive i loko o ke kaʻapuni a i ʻole ka ʻōnaehana (Hiki ke manaʻo ʻia ka Capacitance Distributed e like me nā mea hiki ke manaʻo ʻia).ʻOi aku ka lōʻihi o ka uwea ʻana i ka puʻunaue ʻana i ka mana a hoʻonui i ka leakage o kēia manawa.
ʻO ke kumu o ke ana ʻana i ka leakage i kēia manawa, ua like ia me ke ana ʻana i ka pale ʻana.ʻO ke ana ʻana i ke kūpaʻa insulation he ʻano leakage o kēia manawa, akā ua hōʻike ʻia ma ke ʻano o ke kū'ē.Eia nō naʻe, pili ka ana maʻamau o ka leakage i ka uila kamaʻilio, no laila ke ana ʻia ka leakage.
Loaʻa i ka ʻāpana o kēia manawa kahi ʻāwī paona paona.
I ka manawa o ka Inspection Voltage Withstand, I mea e mālama ai i nā lako hoʻokolohua a nānā i nā hōʻailona ʻenehana e like me nā lula, pono nō hoʻi e ʻae ʻia kahi ikaika kiʻekiʻe o ke kahua uila e hōʻino ʻole i ka lako ma lalo o ka hoʻāʻo ʻana (mea insulation) Kahe ʻana ma o nā lako ma lalo o ka hoʻāʻo ʻana (mea insulation) * ka waiwai nui o kēia manawa, ua kapa ʻia kēia ʻano leakage current, akā hoʻohana wale ʻia kēia ʻano i nā manawa kikoʻī ma luna.E ʻoluʻolu e ʻike i ka ʻokoʻa.
ʻO ka Program-Controlled Leakage Current Tester ʻOiaʻiʻo ʻo ke Kaapuni Uila a i ʻole nā lako e kahe ana ma ka ʻāpana insulation me ka ʻole o nā hemahema a me ka uila i hoʻohana ʻia.
ʻO kēia manawa.No laila, ʻo ia kekahi o nā hōʻailona koʻikoʻi e ana i ka insulation o nā mea uila, a ʻo ia ka hōʻailona mua o ka hana palekana huahana.
E mālama i ka Leakage o kēia manawa ma kahi waiwai liʻiliʻi, e hana ana i kahi kuleana koʻikoʻi i ka hana palekana o nā huahana i mua.
Hoʻohana ʻia ka Programmable Leakage Current Tester e ana i ka leakage o kēia manawa ʻaʻole i pili i ka hana i hana ʻia e ka mana o ka mana hana (a i ʻole nā mana ʻē aʻe) o ka mea uila uila ma o ka insulation a i ʻole ka hoʻokaʻawale ʻana i ka Parameter Impedance, a me kāna Impedance hoʻokomo i ka Impedance o ke kanaka. Kino.
Leakage Current Checker is mainly Composed Of Impedance Conversion, Range Conversion, AC-DC Conversion, Expansion, Indicating Equipment, Etc. Aia no hoi kekahi i ka Over-Current Maintenance, Sound and Light Alarm Circuit and Experimental Voltage Scheduling Equipment, a me ko lakou mau mea hoike ua maheleia. I loko o ka Analog a me ka Digital ʻElua ʻano.
ʻO ka mea i kapa ʻia ʻo Touch Current, ma ka pōkole, e pili ana i ke kahe e kahe ana ma ka ʻāpana metala hiki ke hoʻopā ʻia ma o ke kino kanaka i ka ʻāpana honua a i ʻole ka ʻāpana hiki ke hoʻopā ʻia.No kēia, pono mākou e hoʻohana iā ia i ka nānā ʻana i ke kaapuni hoʻohālikelike kino kanaka, Voltmeter Parallel, a ʻo ke kaʻapuni hoʻohālikelike o ke kino kanaka he mau ʻokoʻa kaapuni hoʻohālikelike kino kanaka e like me nā lula palekana o nā huahana.
ʻEhā ʻano o ka leakage o kēia manawa: Semiconductor Component Leakage Current, Power Supply Leakage Current, Capacitor Leakage Current and Filter Leakage Current.
Inoa Pākē: Leakage Current;Inoa Haole: Leakage Current
1 Leakage o na mea Semiconductor
2 Mana Leaka ʻia
3 Kahiko Leaka ʻia
4 Kānana Leakage ʻĀnō
1. Leakage o kēia manawa o nā ʻāpana Semiconductor
Ke kahe nei kekahi au liʻiliʻi loa ma ka hui PN ke hemo.Ke hoʻonoho ʻia ʻo DS i ka ʻaoʻao mua a hoʻohuli ʻia ʻo GS, ma hope o ka wehe ʻia ʻana o ke kahawai Conductive, e kahe ana ke ʻano mai D a i S. Akā ʻo ka mea ʻoiaʻiʻo, no ka loaʻa ʻana o nā Electron Free, ua hoʻopili ʻia nā Electron Free i ka SIO2 a me N+, e kumu. DS e lele i kēia manawa.
2. Ka Leaka Ka Mana
I mea e hōʻemi ai i ka pilikia ma ka hoʻololi ʻana i ka mana, e like me ka National Standard, pono e hoʻokomo ʻia kahi EMI Filter Circuit.Ma muli o ka pili ʻana o ka EMI Circuit, aia kahi ʻāwī liʻiliʻi i ka honua ma hope o ka hoʻopili ʻia ʻana o ka mana hoʻololi i ka mana, ʻo ia ke ʻano leakage.Inā ʻaʻole ia i hoʻopaʻa ʻia, e loaʻa ana i ka pūpū kamepiula kahi volta 110 volts i ka honua, a e manaʻo ʻo ia i ka ʻeha ke hoʻopā ʻia e ka lima, kahi e pili pū ai i ka hana kamepiula.
3. Ka capacitor Leakage ia
ʻAʻole hiki ke ʻoi aku ka maikaʻi o ka Capacitor Medium i ka non-conductivity.Ke hoʻohana ʻia ka Capacitor me kahi Voltage DC, e loaʻa ana i ka Capacitor ka leaka o kēia manawa.Inā Nui loa ka ʻĀpana Leaka, E pōʻino ka Capacitor i ka wela.Ma waho aʻe o nā Electrolytic Capacitors, ʻo ka Leakage Current o nā Capacitors ʻē aʻe he liʻiliʻi loa, no laila ua hoʻohana ʻia ka ʻāpana kūʻē i ka insulation no ka hōʻike ʻana i kāna hana insulation;A ʻo ka Electrolytic Capacitor He ʻĀpana Leaka Nui, No laila Hoʻohana ʻia ka ʻĀpana Leakage e hōʻike i kāna hana insulation (Pono i ka Capacity).
ʻO ka hoʻopili ʻana i kahi ʻuala hana DC hou i ka Capacitor e ʻike i ka loli nui ʻana o ka hoʻouka ʻana o kēia manawa, a laila e emi iho me ka manawa.Ke hiki i kekahi waiwai hope, ua kapa ʻia ka waiwai hope o kēia manawa i hiki i kahi kūlana paʻa.
ʻEhā, kānana Leakage ʻĀnō
ʻO ka wehewehe ʻana o ke au leakage o ke kānana lako mana: ʻo ke ʻano mai ka pahu kānana a hiki i ka hopena hoʻopaʻapaʻa ʻole o ka laina e komo mai ana ma lalo o ka voltage kamaʻilio hou.
Inā hoʻokaʻawale loa ʻia nā awa a pau o ka kānana mai ka hale, ʻo ka waiwai o ka leakage e hilinaʻi nui ʻia i ka leakage au o ka CY, ʻo ia hoʻi, hilinaʻi nui i ka hiki o ka CY.
No ka mea e pili ana ka leakage kānana i ka palekana pilikino, loaʻa i nā ʻāina āpau o ka honua i nā kānāwai koʻikoʻi ma luna o ia: No ka lako mana 220V / 50Hz Communication Grid, ʻo ka leakage o ka kānana walaʻau e koi ʻia ma lalo o 1mA.
