Electrolytic Capacitors ke Lebaka le ka Sehloohong la Bophelo bo Bokhutšoane ba Mabone a LED
Hangata ho utloahala hore bophelo bo khutšoanyane ba mabone a LED bo bakoa haholo-holo ka lebaka la bophelo bo khutšoanyane ba matla a motlakase, 'me bophelo bo khutšoanyane ba matla a motlakase bo bakoa ke nako e khutšoanyane ea electrolytic capacitor. Lipolelo tsena le tsona li na le moelelo. Hobane 'maraka o tletse ka palo e kholo ea li-electrolytic capacitor tsa nakoana le tse tlase, hammoho le taba ea hore joale ba loantšana le theko, bahlahisi ba bang ba sebelisa li-electrolytic capacitor tsena tse tlase tsa nako e khuts'oane ho sa tsotelehe boleng.
Ntlha ea pele, bophelo ba electrolytic capacitor bo itšetlehile ka mocheso o potolohileng.
Bophelo ba electrolytic capacitor bo hlalosoa joang? Ehlile, e hlalosoa ka lihora. Leha ho le joalo, haeba index ea bophelo ea electrolytic capacitor ke lihora tse 1 000, ha ho bolele hore capacitor ea electrolytic e robehile ka mor'a lihora tse sekete, ha ho joalo, empa ke feela hore bokhoni ba electrolytic capacitor bo fokotsehile ka halofo ka mor'a lihora tse 1 000, tse neng li le teng. qalong 20uF. Hona joale ke 10uF feela.
Ho phaella moo, index ea bophelo ea electrolytic capacitors e boetse e na le tšobotsi eo e tlamehang ho boleloa hore na ke likhato tse kae tsa bophelo ba mocheso oa tikoloho ea ho sebetsa. 'Me hangata e hlalosoa e le bophelo ba mocheso oa 105 ° C.
Lebaka ke hobane li-electrolytic capacitor tseo re tloaetseng ho li sebelisa kajeno ke li-electrolytic capacitor tse sebelisang mokelikeli oa electrolyte. Ha e le hantle, haeba electrolyte e omme, capacitance e tla be e felile. Ha mocheso o phahame, electrolyte e fetoha mouoane habonolo. Ka hona, index ea bophelo ea electrolytic capacitor e tlameha ho bonts'a bophelo tlas'a mocheso ofe oa mocheso.
Kahoo li-capacitor tsohle tsa electrolytic hajoale li tšoailoe ho 105 ° C. Ka mohlala, motlakase o tloaelehileng oa electrolytic o na le nako ea bophelo ea lihora tse 1 000 feela ho 105 ° C. Empa haeba u nahana hore bophelo ba li-capacitor tsohle tsa electrolytic ke lihora tse 1 000 feela. Hoo e ka ba phoso haholo.
Ka mantsoe a bonolo feela, haeba mocheso oa tikoloho o phahame ho feta 105 ° C, bophelo ba eona bo tla ba ka tlase ho lihora tse 1,000, 'me haeba mocheso o ka tlaase ho 105 ° C, bophelo ba eona bo tla ba nako e telele ho feta lihora tse 1,000. Joale na ho na le kamano e matla ea palo lipakeng tsa bophelo le mocheso? Ee!
E 'ngoe ea likamano tse bonolo le tse bonolo ho bala ke hore bakeng sa keketseho e' ngoe le e 'ngoe ea likhato tse 10 mocheso oa tikoloho, nako ea bophelo e fokotseha ka halofo; ka lehlakoreng le leng, bakeng sa phokotso e 'ngoe le e 'ngoe ea likhato tse 10 mochesong oa tikoloho, nako ea bophelo e imena habeli. Ehlile ena ke khakanyo e bonolo feela, empa hape e nepahetse.
Hobane li-electrolytic capacitor tse sebelisoang bakeng sa matla a ho khanna a LED li hlile li behiloe ka har'a ntlo ea lebone la LED, re hloka feela ho tseba mocheso ka har'a lebone la LED ho tseba bophelo bo sebetsang ba electrolytic capacitor.
Hobane ka mabone a mangata LED le electrolytic capacitor li kenngoa ka har'a casing e le 'ngoe, mocheso oa tikoloho oa bobeli o tšoana feela. 'Me mocheso ona oa tikoloho o khethoa haholo-holo ke ho leka-lekana ho futhumatsa le ho pholisa ha LED le phepelo ea matla. 'Me maemo a futhumatsang le a pholileng a lebone le leng le le leng la LED a fapane.
Mokhoa oa ho lelefatsa bophelo ba electrolytic capacitor
① Lelefatsa bophelo ba eona ka moralo
Ha e le hantle, mokhoa oa ho lelefatsa bophelo ba li-capacitor tsa electrolytic o bonolo haholo, hobane qetello ea eona ea bophelo e bakoa haholo-holo ka lebaka la ho tsoa ha mokelikeli oa electrolyte. Haeba tiiso ea eona e ntlafatsoa 'me e sa lumelloe ho fetoha mouoane, ka tlhaho bophelo ba eona bo tla lelefatsoa.
Ho phaella moo, ka ho amohela sekoahelo sa polasetiki sa phenolic se nang le electrode ho pota-pota ka kakaretso, le gasket e khethehileng e habeli e kopantsoeng ka thata le khetla ea aluminium, tahlehelo ea electrolyte e ka boela ea fokotseha haholo.
② Lelefatsa bophelo ba eona ho tloha ho sebelisoa
Ho fokotsa nako ea eona ea ripple le hona ho ka lelefatsa bophelo ba eona ba tšebeletso. Haeba ripple current e le kholo haholo, e ka fokotsoa ka ho sebelisa li-capacitor tse peli ka ho lekana.
Ho sireletsa li-capacitor tsa electrolytic
Ka linako tse ling esita le haeba nako e telele ea electrolytic capacitor e sebelisoa, hangata ho fumanoa hore electrolytic capacitor e robehile. Lebaka la see ke lefe? Ha e le hantle, ho fosahetse ho nahana hore boleng ba electrolytic capacitor ha boa lekana.
Hobane rea tseba hore marang-rang a matla a AC a matla a toropo, hangata ho ba le ho phahama ha motlakase o phahameng hang hang ka lebaka la ho otla ha lehalima. Le hoja mehato e mengata ea tšireletso ea lehalima e sebelisitsoe bakeng sa ho otla ha lehalima holim'a marang-rang a maholo a matla, ho ntse ho ke ke ha qojoa hore ho tla ba le ho lutla ha marang-rang ho baahi ba Lehae.
Bakeng sa mabone a LED, haeba a tsamaisoa ke lisebelisoa tse kholo, o tlameha ho eketsa mehato e thibelang ho phalla ho li-terminals tse kenyang motlakase ka matla a lebone, ho kenyelletsa le li-fuse le li-resistors tse sireletsang overvoltage, tse atisang ho bitsoa varistors. Sireletsa likarolo tse latelang, ho seng joalo li-capacitor tsa nako e telele tsa electrolytic li tla phunyeletsoa ke matla a ho phahama.
