1. hewa 'ano a me ka mālama' ana i ka capacitance o hanalima e hooponopono huakai kaapuni a ka papa
Ke ole o ka capacitance poho o ka mea kiʻekiʻe loa i loko o mīkini uila no, o ka oi aku i loko o ka hihia o electrolytic capacitance.
Ua hoike mai ke capacitance ole like penei: 1.The nona mea uuku; 2. Huina lilo o ka nona iho; 3. Ke kulu; 4. He pōkole puni.
Pāʻani Capacitors he okoa kūlana i loko o ka huakai kaapuni, a me ka hoʻolako 'ole' e characterized.In ka hanalima hooponopono pai huakai kaapuni a ka papa, Ka mīkini huakai kaapuni papa o ka nui, ka mea pihana ua hoʻohana 'ia e hana i ka mana Kānana, ka hōʻailona kihi e hui ai, a me ka capacitance o ka oscillator huakai kaapuni e less.If ka electrolytic mea pihana hoʻohana ma o ka ka hoʻololiʻana mana lako ua poino, i ka ka hoʻololiʻana mana lako ke ole e vibrating, a he mea ole anakahi uila output.Or auaiaea anakahi uila kānana mea i maikai, i ke kaapuni ma muli o ke anakahi uila instability a me Logical hilahila, i ka hana ana o ka mīkini hana hola a hiki i wehe i ka mīkini, ina o ka mea pihana, a me nā kikohoʻe huakai kaapuni papa ka mana kokuaia ma waena o ka 'oluʻolu a me ka io, i ka hana ana o ka above.This mea pakahi aku la ia ikaika kokoke i ke kamepiula motherboard, he nui kamepiula hoʻohana mea akaka i kekahi manawa, hiki ole wehe i ka mīkini no na makahiki, ka kŰia o kekahi manawa huli ana, wehe i ka hihia, pinepine i electrolytic mea pihana kui kŰia hiki ke ike, ina o ka mea pihana ilalo e ana nona iho ka nui malalo o ka maoli cia e loaʻa.
Ke ola o ka mea pihana mea pololei nā i Ambient ana wela. Ke kiekie o ka? Aneie ana wela, i ka pōkole o ka mea pihana life.This aliʻi,ʻaʻole wale nō pili i ka electrolytic capacitors akā pū i nā capacitors.Therefore, ma ka hulina no ka hoʻokō 'ole' capacitance, ia mea pono, e kaha i ka capacitance i mea kŘpa a kokoke i ka wela kahi, e like me ka capacitance ma kaʻaoʻao o ka radiator, a me ka mana kiʻekiʻe akoakoa eiiiiiaiou. Ke kokoke ia ia, o ka oi paha ia mea ia e damaged.Have ua ho'āla hou aʻelaʻo ka X-Ray flaw mīkini hopu ka mea hewa ka mana lako, mea hoʻohana noonoo i ka uahi i hele mai, mai ka mana lako, wehe i ka hihia ma hope ana o ka 1000 Bufa / 350 V nui mea pihana i ka oily ukana mai, haehae hamama iho mai nei au i ka 'auhau o wale he mau umi o Bufa, i ike ia wale i ka capacitance o ka rectifier alahaka a me ka wela poho iho alalo,' ē aʻe, mai kahi loihi ka kōna, ka naʻe ia normal.In hou, aia no he pōkole kaapuni i loko o ka capacitance o Kina? inoaia, a me ka ia no hoi loaa i ka mea pihana mea kokoke i ka paio hahana maoli nō parts.Therefore, ka mea e e hoʻomōhala ka wā hulina, no ka hoʻoponopono.
Kekahi capacitive kulu ka mea nui, me ka manamana lima nano hiki i wela, pono hoʻololi i kēiaʻano o ka mea pihana.
Ma ka hihia o ka pono a me ka hewa breakdowns, o ka loa e like me ka hewa o ka holo pono o ka capacitance damage.So ma ka hoʻokō 'ole', capacitance hiki e kī ke kikoo, ma hope o ka loli o ka capacitance mea pinepine kahaha ko oukou naau (o ka papa ana hoi ia e hoʻolohe i ka mea e like ai o ka capacitance, koho maikaʻi ahi, e like me saredio,ʻeleʻele daimana a me ka e like).
2. 'ano a me ka hoʻokae' o ka e kū'ē'ē mai poho
Resistors i na eiiiiiaiou oi aku ka nui i ka uila pono, akā,ʻaʻole i ka loa poino components.Resistance ka pōʻino o ka loa e like me kaʻaoʻao, e wehe i ke alanui, a me ka ia'ku mea pohihihi keia, a me ka ia'ku ka loa rare.Common kalapona ho film ia'ku, metala ho film ia'ku, uea eha ia'ku a me ka lapaʻau resistance.The loa kaiāulu mua elua ano o ia'ku, i ke ano o kona poho mea he haʻahaʻa ia'ku (ma lalo 100 Ω) a me ka kiʻekiʻe waiwai (oi ma mua o 100 ke k Ω) poho i kela mea kiekie, waena ia'ku (e like me he mau haneri i na umi o na tausani o Europa) uuku poino; ka lua o ka mea i ka ia'ku o haʻahaʻa ia'ku ua pinepine charred a me ka eleele, a me ia mea maʻalahi ka loaʻa i ka mea, he mau hoailona ia o ka ia'ku o kiʻekiʻe ia'ku o damaged.Wire eha ia'ku ua nui hoʻohana like me ka nuiʻikena kali kahe, a me ka ia'ku mea i large.Some o ka paukūʻolokaʻa kaula hiki ke blackened aʻilikai he mālili, he mawae pahaʻaʻohe marks.Cement ia'ku mea heʻano o ka uea wou Makalu ia'ku, a e wawahi i ka wā i kuni ai, i ole ia,ʻaʻole nō he hiki trace.When ka lapaʻau ia'ku puhi, e puhi kekahi surfaces i kekahi apana o ka ili, kekahi o i mea ole kumumea, akā, ka mea e loa e blackened.According ana i ka luna ano, i ka wa o kéu ka ia'ku, hiki ke hoʻomōhala ia, koke hōʻike i ka poino e kū'ē'ē mai.
E like me ka ano o ka helu 'ia ma luna, ua hiki mua nana i ka mea haʻahaʻa ia'ku loina no kekahi hoailona o blackened ma pai kaapuni papa , a laila, e like me ka poino i ka mea uie kekahi hapanui hewahewa o ka hamama a me ka waiwai lilo nui a me ka oluolu, e pōʻinoʻia i nā' ano o kiʻekiʻe ia'ku cia, ua hiki ke hoʻohana i ka multimeter pololei ka leo kiʻekiʻe loa ia'ku ma ka pcb huakai kaapuni papa ma nā wēlau o ka ia'ku o ka ia'ku, ina o ka nui o ka ia'ku, ua oi aku ma mua o palena iki cia, o ka ia'ku pono e poino (e lohe ia, e like me nā lio nui ia'ku hoike wale hope i ka hopena, no ka mea, e shunt capacitance ma ka huakai kaapuni a eiiiiiaiou, aia no he kauoha a me ka hookuuia kaʻina), ina o ka nui o ka ia'ku mea uuku ma mua o palena iki waiwai, e nui mai i ke kāpae'ōlelo ia. a pehea oe e ana i na mea pale mū holapū i ka pai ia huakai kaapuni papa pcb, a ina o ka "hewa" he tausani,ʻaʻole ia e hoʻokuʻu hoʻokahi.
3.the loiloi 'ano o ka hana ana pahu hoʻonui leo
Hana ana pahu hoʻonui leo o ka discriminant no ka hala loa he mau lolouila malama loaʻa kekahi pilikia,ʻaʻole wale nō ke degere o ka moʻomeheu pili, manaʻolana ka mea, e kōkuaʻoe, e kūkākūkā i kēia meʻoe.
Ka mea maikaʻi hana ana pahu hoʻonui leo i na ano o ka "ʻike kamepiula pōkole" a me ka "ʻike kamepiula wanaao ae". Kēia mau 'ano, ua nui pono no ke kālailai i ka amo kaapuni o ka laina application.In mea e hōʻoia' laina noi, pono hana amo lalo paʻa loop (io manaʻo) .If ka mea, aohe io manaʻo, me ka hamama loop amplification mea he comparator.If ka lima kūlana kiʻekiʻe mea ia e hookolokoloia mai ai, ka mea e ike, ina paha o ka mea ua hoʻohana 'ia e like me he pahu hoʻonui leo a me ka comparator i loko o ka huakai kaapuni.
