Yadda za a duba a capacitor

Capacitors ne yadu used da kuma m, a hanyoyin sadarwa na zamani, musamman a Electronics. Radio aikin injiniya da kuma talabijin kayan aiki, radar, telephony da telegraphy, aiki da kai da kuma m iko, sarrafa kwamfuta na'urorin da lantarki na'urorin, Laser fasahar - wannan ba irga na yankunan da aikace-aikace. Suna amfani da kusan dukkan sassa na tattalin arziki.

A sarari yake cewa irin wannan m aikace-aikace na capacitors haddasawa da kuma bambancin jinsi. Tare da dada capacitors, akwai real Refayawa yin la'akari da dama tons. Ƙãruwa iya Range daga wani sulusi da murabba'i na PF zuwa daruruwan dubbai na microfarads, da kuma maras aiki irin ƙarfin lantarki iya zama a cikin kewayon daga 'yan volts zuwa yawa daruruwan kilovolts.

A zamaninmu, a kowane gida akwai duk wani nau'i na iyali kayan, kuma, saboda haka, da kuma capacitors. Abin baƙin ciki, sau da yawa suka kasa domin dalilai daban-daban, don haka tambaya taso, da yadda za a gwada wani capacitor da multimeter, magwajin ko ohmmeter.

A aikace, mafi sau da yawa akwai bukatar a duba a kan samfurin da m asarar damar. Dalilin da hutun da ake dangantawa da wani gagarumin wuce haddi na da halatta aiki irin ƙarfin lantarki. Yawanci, da waje alamun rashin lafiya za a iya gani a cikin gidaje kashi - spots, kumburi, fasa, da dai sauransu ...

Yadda za a duba multimeter capacitor

m duniya na'urar for lantarki gwaji - Multimeter. Kafin ka duba capacitor, dole ne a unloaded. Yana yana da muhimmanci musamman don tsayar, da suka fara da tabbaci iyakacin duniya capacitor, halin high iya aiki, high aiki irin ƙarfin lantarki. Rashin yin haka zai lalata mita. Domin sallamar low-ƙarfin lantarki capacitor isa ya gajarta da'ira ta karshe, kuma ya sallame ta high-ƙarfin lantarki capacitor ne a yi ta cikin resistor zuwa 10 ohms, don kauce wa tartsatsi. A lokaci guda da hannunsa taba karshe ba zai iya zama, ko m bugu bayar.

Yana da muhimmanci a san daidai da yadda za a duba capacitor a kowane irin hali, saboda gwaji hanyoyin su ne dogara a kan al'amurra da dama.

A mafi sauki hanyar inganta a multimeter ciwon aiki na capacitance ji, duk da haka, a lokaci guda bai kamata mu manta da bukatar girmama dokoki na polarity lokacin da yin amfani da iyakacin duniya capacitors.

Duba multimeter capacitors da ciwon ba musamman aiki, yana yiwuwa a cikin juriya da aunawa yanayin. By sauya sheka da mita a cikin wannan yanayin, kana bukatar ka taba yi bincike ga capacitor leads da kuma jira 'yan seconds to duba karatu. Idan kayan bayyana rashin iyaka manyan juriya darajar - da capacitor ne OK, idan sifili - daga oda. Idan lambar a kan nuni nuna wasu matsakaiciyar daraja, da capacitor yana da wani zuba da kuma rasa wasu cajin.

Saboda haka, da damar da mita ba tare da tabbaci aiki ba ka damar saka kawai ingantaccen halaye na capacitor, amma, a kalla, ya sa ya yiwu su kusantar da karshe game da bukatar sauya shi.

Duk da haka, wannan gwajin bar amshin na gaba tambaya - yadda za a duba capacitor kewaye. Damage wannan irin na iya faruwa idan wani partially ko gaba daya lalace dielectric mutunci a cikin cell. Irin wannan capacitor ma ya nuna iyaka juriya, amma su dõgara a kan wannan adadi a matsayin hujja da ta mai kyau ne ba zai yiwu ba.

Sanin yadda za a duba capacitor magwajin, ka kuma iya sanin ko iyãwarsa iyaka kayyade tolerances. Ilimi na real damar zama dole domin yin wani yanke shawara game da sauyawa ko kara yin amfani.
