Kuyang’ana kwa Induction Melting Furnace Repairing Fixed Capacitors
Kuyendera kwa Kuchotsa Kutentha Kwambiri Kukonza Ma Capacitor Okhazikika
(1) Dziwani ma capacitor ang’onoang’ono pansi pa 10pF. Chifukwa mphamvu ya capacitor yokhazikika pansi pa 10pF ndi yaying’ono kwambiri, poyezera ndi ma multimeter, imatha kuyang’aniridwa bwino ngati ikutuluka, kuzungulira kwamkati kapena kuwonongeka. Poyezera, mutha kusankha multimeter R × 10k chipika, ndikugwiritsa ntchito zolembera ziwiri za mita kuti mulumikizane ndi zikhomo ziwiri za capacitor mwachisawawa, ndipo kukana kuyenera kukhala kopanda malire. Ngati muyeso woyezera kukana (cholozera chakumanja) ndi zero, zikutanthauza kuti capacitor yawonongeka ndi kutayikira kapena kugwedezeka kwamkati.
(2) Dziwani ngati 10pF~1000uF capacitor yokhazikika ikulipira, ndiyeno weruzani mtundu wake, ma multimeter amasankha zida za Rx1k. Ngati mtengo wa B wa ma triodes awiriwo ndi woposa 100, ndipo mphamvu yolowera iyenera kukhala yaying’ono, 3Dc6 ndi mitundu ina ya triodes ingagwiritsidwe ntchito kupanga chubu chophatikizika. Mayeso ofiira ndi akuda a ma multimeter amalumikizidwa motsatana ndi emitter e ndi wokhometsa c wa chubu chophatikizika. Chifukwa cha kukulitsa kwa transistor yophatikizika, kuthamangitsa ndi kutulutsa ndi mphamvu ya capacitor yoyesedwa kumakulitsidwa, kotero kuti kugwedezeka kwa pointer kwa multimeter kumawonjezeka. Kuti athe kuwongolera kuwonera. Tiyenera kukumbukira kuti panthawi yoyesera, makamaka poyezera ma capacitors omwe ali ndi mphamvu zochepa, mapini okhudzana ndi pini a capacitor omwe akuyesedwa ayenera kusinthidwa mobwerezabwereza, kuti kayendetsedwe ka pointer ya multimeter iwoneke bwino. ,
(3) Kwa ma capacitor okhazikika pamwamba pa 1000uF, fayilo ya Rx10k ya multimeter ingagwiritsidwe ntchito kuyesa mwachindunji ngati capacitor ili ndi njira yolipiritsa, komanso ngati pali dera lalifupi lamkati kapena kutayikira, ndipo mphamvu ya capacitor ikhoza kuwerengedwa molingana ndi kukula kwa cholozera kutembenukira kumanja.
