Yadda za a magance matsalar lokacin da high-frequency quenching kayan aiki ya sami laifi?

1. Al’amarin kuskure Na’urar kashe mitoci masu yawa suna gudana akai-akai, amma ana iya jin ƙarar ƙara mai kaifi lokaci zuwa lokaci, kuma voltmeter na DC yana ɗan girgiza. Yi amfani da oscilloscope don lura da yanayin ƙarfin lantarki a ƙarshen gadar inverter. Ana iya ganin cewa lokacin inverter gajere ne, sake zagayowar daya ya kasa ko kuma gajeriyar lokacin da ba a iya tantancewa ta kasa, sannan kuma parallel resonant inverter circuit ya kasa kasa na wani kankanin lokaci, amma lokacin dawo da kai gajere ne, gazawar kuma ita ce. kullum da inverter iko. Wani sashi nasa yana damuwa da bugun bugun gyare-gyare, kuma gazawar na ɗan lokaci gabaɗaya yana faruwa ne sakamakon rashin kyawun rufewar da ke tsakanin jujjuyawar taswirar mitar mitar.

2. Al’amarin kuskure Bayan na’urorin kashe mitoci masu yawa suna gudana akai-akai na ɗan lokaci, kayan aikin suna da sauti mara kyau, kuma karatun mita yana girgiza kuma kayan aikin ba su da ƙarfi. Hayaniyar da ba ta dace ba tana faruwa bayan kayan aikin suna aiki na ɗan lokaci. Aikin ba shi da kwanciyar hankali, musamman saboda halayen thermal na kayan lantarki na kayan aiki ba su da kyau. Za a iya raba sassan lantarki na kayan aiki zuwa sassa biyu: rauni mai rauni da ƙarfin halin yanzu, kuma ana iya gano sashin sarrafawa daban don hana lalacewa. Lokacin da babban na’urar wutar lantarki ba ta haɗa da babban wutar lantarki ba, kawai wutar lantarki na sashin sarrafawa ne kawai ke kunna. Bayan sashin kulawa ya yi aiki na ɗan lokaci, yi amfani da oscilloscope don gano bugun bugun jini na allon sarrafawa don ganin ko bugun bugun yana al’ada.

Dangane da tabbatar da cewa babu matsala a cikin sashin sarrafawa, kunna kayan aiki, kuma bayan abin da ya faru na al’ada ya faru, lura da yanayin jujjuyawar wutar lantarki na kowane thyristor tare da oscilloscope, kuma gano thyristor tare da halayen thermal mara kyau; idan yanayin juzu’in ƙarfin lantarki na thyristor ya kasance Duk na al’ada ne. A wannan lokaci, ya kamata mu kula da ko akwai matsaloli tare da sauran lantarki aka gyara, da kuma kula na musamman ga kewaye breakers, capacitors, reactors, tagulla mashaya lambobin sadarwa da kuma manyan gidajen wuta.
