Duban Induction Melting Furnace Gyaran Kafaffen Capacitors
Dubawa na Rushewar Wuta Gyara Kafaffen Capacitors
(1) Gano ƙananan capacitors ƙasa da 10pF. Saboda ƙarfin madaidaicin capacitor da ke ƙasa da 10pF ya yi ƙanƙanta sosai, lokacin aunawa tare da multimeter, ana iya bincika shi da inganci kawai don yayyo, gajeriyar da’ira na ciki ko rushewa. Lokacin aunawa, zaku iya zaɓar toshe multimeter R × 10k, kuma kuyi amfani da alƙalami na mita biyu don haɗa fil biyu na capacitor ba da gangan ba, kuma juriya ya kamata ya zama marar iyaka. Idan ƙimar juriya da aka auna (mai nunin yana juyawa zuwa dama) sifili ne, yana nufin cewa capacitor ya lalace ta hanyar ɗigogi ko girgiza ciki.
(2) Gano ko 10pF~1000uF kafaffen capacitor yana caji, sannan yanke hukunci ingancinsa, multimeter yana zaɓar kayan aikin Rx1k. Idan darajar B na triodes biyu ya fi 100, kuma shigar azzakarinsa ya kamata ƙarami, 3Dc6 da sauran nau’ikan triodes za a iya amfani da su don samar da bututu mai hade. Hanyoyin gwajin ja da baki na multimeter ana haɗa su da emitter e da mai tarawa c na bututu mai hadewa. Saboda tasirin haɓakawa na transistor composite, caji da fitarwa da tsarin wutar lantarki na capacitor a ƙarƙashin gwaji suna haɓaka, ta yadda ma’aunin nuni na multimeter ya karu. Don sauƙaƙe lura. Ya kamata a lura cewa yayin aikin gwajin, musamman lokacin auna ma’aunin capacitors tare da ƙaramin ƙarfin, dole ne a sake musanya wuraren hulɗar fil na capacitor a ƙarƙashin gwajin, don a iya ganin motsin ma’aunin multimeter a sarari. ,
(3) Don ƙayyadaddun capacitors sama da 1000uF, ana iya amfani da fayil ɗin Rx10k na multimeter don gwada kai tsaye ko capacitor yana da tsarin caji, kuma ko akwai gajeriyar kewayawa ta ciki ko ɗigo, kuma ana iya ƙididdige ƙarfin capacitor bisa ga girman mai nuni yana lilo zuwa dama.
