i-subwoofer capacitor
Okuqukethwe
Ukusebenza kwama-subwoofers ezimoto ezinamandla kungase kuhambisane nezinkinga ezihambisana nokusetshenziswa okuphezulu kwamanje kwalawa madivayisi. Ungakuqaphela lokhu eziqongweni ze-bass, lapho i-subwoofer "iminceka".
Lokhu kungenxa yokwehla kwe-voltage kokokufaka kwamandla e-subwoofer. Idivayisi yokugcina amandla, indima yayo edlalwa amandla e-capacitor afakwe kumjikelezo wamandla we-subwoofer, isiza ukulungisa inkinga.
Kungani udinga i-capacitor ye-subwoofer
I-capacitor kagesi iyisisetshenziswa esinezigxobo ezimbili esikwazi ukunqwabelana, sigcine futhi sikhiphe ishaja kagesi. Ngokwesakhiwo, iqukethe amapuleti amabili (amapuleti) ahlukaniswe yi-dielectric. Isici esibaluleke kakhulu se-capacitor yi-capacitance yayo, ebonisa inani lamandla elingawagcina. Iyunithi ye-capacitance yi-farad. Kuzo zonke izinhlobo ze-capacitor, ama-electrolytic capacitors, kanye nezihlobo zabo ezithuthukisiwe, ionistors, zinamandla amakhulu.
Ukuze uqonde ukuthi kungani i-capacitor idingeka, ake sithole ukuthi kwenzekani kunethiwekhi kagesi yemoto lapho umsindo wemoto we-low-frequency enamandla angu-1 kW noma ngaphezulu uvuliwe. Ukubala okulula kubonisa ukuthi okwamanje okudliwe yizisetshenziswa ezinjalo kufinyelela ku-100 amperes nangaphezulu. Umthwalo unohlamvu olungalingani, i-maxima ifinyelelwa ngezikhathi zamabhithi e-bass. Ukwehla kwamandla kagesi ngesikhathi umsindo wemoto udlula phezulu kwevolumu ye-bass kungenxa yezinto ezimbili:
- Ukuba khona kokumelana kwangaphakathi kwebhethri, kunciphisa amandla ayo okukhipha ngokushesha okwamanje;
- Umthelela wokumelana kwezintambo zokuxhuma, okubangela ukwehla kwe-voltage.
Ibhethri ne-capacitor zisebenza ngokufana. Zombili izisetshenziswa ziyakwazi ukuqongelela amandla kagesi, bese ziwanikeza umthwalo. I-capacitor yenza lokhu ngokushesha okukhulu futhi "ngokuzithandela" kunebhethri. Lesi sakhiwo singaphansi komqondo wokusetshenziswa kwayo.
I-capacitor ixhunywe ngokuhambisana nebhethri. Ngokunyuka okubukhali kokusetshenziswa kwamanje, ukwehla kwamandla kagesi kuwo wonke ukumelana kwangaphakathi kwebhethri kuyanda futhi, ngokufanele, kuncipha kumatheminali okukhiphayo. Kuleli qophelo, i-capacitor ivuliwe. Ikhulula amandla aqoqiwe, futhi ngaleyo ndlela inxephezele ukwehla kwamandla okukhiphayo.
Indlela yokukhetha i-capacitor
I-capacitance edingekayo incike emandleni e-subwoofer. Ukuze ungangeni ezibalweni eziyinkimbinkimbi, ungasebenzisa umthetho olula wesithupha: ku-1 kW yamandla, udinga i-capacitance ye-1 farad. Ukweqa lesi silinganiso kunenzuzo kuphela. Ngakho-ke, i-1 farad high-capacitor emakethe ingasetshenziswa futhi kuma-subwoofers anamandla angaphansi kwe-1 kW. I-voltage yokusebenza ye-capacitor kufanele ibe okungenani i-14 - 18 volts. Amanye amamodeli afakwe i-digital voltmeter - inkomba. Lokhu kudala lula okwengeziwe ekusebenzeni, futhi i-electronics elawula ukushajwa kwe-capacitor yenza le nqubo ibe lula.
Indlela yokuxhuma i-capacitor ku-subwoofer
Ukufaka i-capacitor akuyona inqubo eyinkimbinkimbi, kodwa uma uyenza, udinga ukuqaphela futhi ulandele imithetho ethile:
- Ukuze ugweme ukwehla kwe-voltage ebonakalayo, izintambo ezixhuma i-capacitor kanye ne-amplifier akufanele zibe ngaphezu kwama-cm 50. Ngesizathu esifanayo, ingxenye yesiphambano sezintambo kufanele ikhethwe sikhulu ngokwanele;
- I-polarity kufanele ibhekwe. Intambo ephozithivu evela ebhethrini ixhunywe kutheminali yamandla ephozithivu ye-subwoofer amplifier kanye nasetheminali ye-capacitor ephawulwe ngophawu “+”. Ukukhishwa kwe-capacitor enegama elithi "-" ixhunywe emzimbeni wemoto kanye ne-negative power terminal ye-amplifier. Uma i-amplifier isivele ixhunywe emhlabathini ngaphambili, i-terminal engalungile ye-capacitor ingafakwa nge-nati efanayo, kuyilapho igcina ubude bezintambo ezivela ku-capacitor kuya ku-amplifier ngaphakathi kwemingcele ecacisiwe yama-50 cm;
- Lapho uxhuma i-capacitor ye-amplifier, kungcono ukusebenzisa izinsimbi ezijwayelekile zokuxhuma izintambo kumatheminali ayo. Uma zinganikeziwe, ungasebenzisa i-soldering. Ukuxhumana okusontekile kufanele kugwenywe, i-current ngokusebenzisa i-capacitor ibalulekile.
Umfanekiso 1 ubonisa ukuxhuma i-capacitor ku-subwoofer.
Ungashaja kanjani i-capacitor ye-subwoofer
Ukuze uxhume kunethiwekhi kagesi yemoto, i-capacitor yemoto esivele ishajiwe kufanele isetshenziswe. Isidingo sokwenza lesi senzo sichazwa yizakhiwo ze-capacitor, ezishiwo ngenhla. I-capacitor ishaja ngokushesha lapho iphuma. Ngakho-ke, okwamanje i-capacitor ekhishwe ivuliwe, umthwalo wamanje uzoba mkhulu kakhulu.
Uma i-capacitor ethengiwe ye-subwoofer ifakwe i-electronics elawula ukushaja kwamanje, ungakhathazeki, zizwe ukhululekile ukuyixhuma kumasekhethi kagesi. Uma kungenjalo, i-capacitor kufanele ikhokhiswe ngaphambi kokuxhumeka, ikhawule okwamanje. Kungcono ukusebenzisa isibani semoto esijwayelekile kulokhu ngokusivula ngokumelene nesekhethi yamandla. Umfanekiso wesi-2 ubonisa indlela yokushaja kahle ama-capacitor amakhulu.
Ngesikhathi sokukhanyisa, isibani sizokhanya ngokushisa okugcwele. Ukuphakama okuphezulu kwamanje kuzokhawulwa ngamandla esibani futhi kuzolingana nomthamo wayo olinganiselwe. Ngaphezu kwalokho, ngesikhathi sokushaja, i-incadescence yesibani izoba buthaka. Ekupheleni kwenqubo yokushaja, isibani sizocisha. Ngemuva kwalokho, udinga ukunqamula i-capacitor kusuka kumjikelezo wokushaja. Khona-ke ungakwazi ukuxhuma i-capacitor eshajiwe kumjikelezo wokunikezwa kwamandla we-amplifier.
Uma ngemva kokufunda isihloko usenemibuzo mayelana nokuxhumeka, sincoma ukuthi ufunde isihloko esithi "Indlela yokuxhuma i-amplifier emotweni."
Izinzuzo ezengeziwe zokufaka ama-capacitor ezimotweni
Ngaphezu kokuxazulula izinkinga ngokusebenza kwe-subwoofer, i-capacitor exhunywe kunethiwekhi yemoto inomphumela omuhle ekusebenzeni kwemishini kagesi iyonke. Iziveza kanje:
- I-capacitor iyisihlungi esihle sezingxenye ze-high-frequency ye-voltage ye-mains ezenzeka lapho ushintsha imithwalo kanye nokusebenza kwamanye amadivaysi kagesi, imisebenzi yayo ithinta kahle ukusebenza kwazo zonke izinhlelo zemoto;
- Ukusetshenziswa kwe-capacitor kwenza kube lula ukushelela ukukhuphuka kwamandla kagesi okwenzeka lapho abathengi benethiwekhi ebhodini bevuliwe futhi bevaliwe, okuvumela i-generator ukuthi isebenze ngemodi elinganayo;
- Lapho uqala imoto nge-starter, i-capacitor, yiqiniso, ithatha ingxenye eyengeziwe kuyo, inikeze icala layo kunethiwekhi ebhodini. Lokhu kuyiqiniso ikakhulukazi ebusika, lapho ikhono lebhethri lokunikeza okwamanje liyancipha, futhi izakhiwo ze-capacitor azishintshi.
I-condenser ifakiwe futhi uyabona ukuthi i-subwoofer yakho isiqalile ukudlala ngokuthakazelisa kakhulu. Kodwa uma uzama kancane, ungayenza idlale kangcono nakakhulu, siphakamisa ukuthi ufunde isihloko esithi "Indlela yokusetha i-subwoofer".
