Ukuhlolwa kwe I-Induction Melting Furnace Ukulungisa ama-Fixed Capacitor

(1) Thola ama-capacitor amancane angaphansi kuka-10pF. Ngenxa yokuthi umthamo we-capacitor engaguquki ngaphansi kuka-10pF mancane kakhulu, uma ukalwa nge-multimeter, ingabhekwa kuphela ngekhwalithi yokuvuza, isifunda esifushane sangaphakathi noma ukuphuka. Lapho ukala, ungakhetha i-multimeter R × 10k block, futhi usebenzise amapeni amamitha amabili ukuxhuma izikhonkwane ezimbili ze-capacitor ngokungahleliwe, futhi ukumelana kufanele kungapheli. Uma inani lokumelana elilinganisiwe (isikhombi sijikela kwesokudla) singuziro, kusho ukuthi i-capacitor yonakaliswa ukuvuza noma ukushaqeka kwangaphakathi.

(2) Thola ukuthi i-10pF～1000uF fixed capacitor iyashaja, bese wahlulela ikhwalithi yayo, i-multimeter ikhetha igiya le-Rx1k. Uma inani elingu-B lama-triode amabili lingaphezu kwe-100, futhi okwamanje ukungena kufanele kube kuncane, i-3Dc6 nezinye izinhlobo zama-triodes zingasetshenziswa ukwakha ithubhu eliyinhlanganisela. Imikhondo yokuhlola ebomvu nemnyama ye-multimeter ixhunywe ku-emitter e kanye nomqoqi c weshubhu eliyinhlanganisela. Ngenxa yomphumela wokukhulisa i-transistor ehlanganisiwe, inqubo yokushaja nokukhipha kanye namandla e-capacitor ngaphansi kokuhlolwa iyakhuliswa, ukuze kukhuphuke i-pointer swing ye-multimeter. Ukuze kube lula observation. Kumele kuqashelwe ukuthi ngesikhathi sokusebenza kokuhlolwa, ikakhulukazi lapho kulinganisa ama-capacitor ane-capacitance encane, amaphuzu okuxhumana wephinikhodi ye-capacitor ngaphansi kokuhlolwa kufanele ashintshwe ngokuphindaphindiwe, ukuze ukunyakaza kwe-pointer ye-multimeter kubonakale ngokucacile. ,

(3) Kuma-capacitor angaguquki ngaphezu kuka-1000uF, ifayela le-Rx10k le-multimeter lingasetshenziswa ukuhlola ngokuqondile ukuthi i-capacitor inenqubo yokushaja, nokuthi ingabe kukhona ukujikeleza okufushane kwangaphakathi noma ukuvuza, futhi umthamo we-capacitor ungalinganiswa ngokuvumelana ubukhulu besikhombi bujikela kwesokudla.
