Yana da matukar kowa a cikin inverter masana'antu. Yaya za a bincika kuskuren bayan an yi amfani da inverter na dogon lokaci?
Don sanya inverter yayi aiki kullum, dole ne a girka shi bisa ƙa'ida daidai da takamaiman bayani na fasaha da umarnin mai inverter lokacin da aka yi amfani da shi, kuma dole ne ya cika buƙatun shigar da wutar lantarki da yanayin amfani. Voltagearfin shigarwar da aka saba amfani da shi na mai juyawa kashi uku ne 380V480 V, wanda zai iya canzawa gaba 10%. Mitar ƙarfin shigar da gajeren zango ita ce 50 / 60Hz, kuma saurin hawa 5% ne. Keɓaɓɓun masu sauya mita wani al'amari ne.
1. Gano kewayen mai gyarawa a cikin tsayayyen ganewar mitar musanya
Lokacin da inverter aka gwada lissafi, shi wajibi ne don gwada rectifier kewaye bayan da inverter aka kashe. Na farko, cire dukkan wayoyin fitarwa na inverter; abu na biyu, sami samfuran DC masu kyau da marasa kyau a cikin inverter, sa'annan ka juya maɓallin multimeter zuwa toshe diode. Na uku, hada bakar bincike da jan bincike zuwa sanduna masu amfani da mara kyau da mara kyau na motar DC da layin fitar da waya uku bi da bi, da kuma rikodin dabi'un lantarki uku da multimeter ya nuna; idan dabi'un da aka auna na multimeter guda shida daidai ne, yana nuna cewa gadar mai gyara ta al'ada ce, in ba haka ba tana nuna Akwai matsala tare da gada mai gyara kuma yana bukatar gyara ko sauyawa.
Gano kewayen Inverter a cikin tsayayyen ganewar mai sauya mita
A cikin gwajin canzawa na inverter, gwajin zagayen inverter da gwajin zagaye mai daidaitawa kusan iri daya ne, kuma duk ana yin su yayin da aka kashe inverter. Bambancin shine cewa a cikin gwajin zagaye na inverter, yakamata a jujjuya maballan multimeter zuwa juriya the 10, yakamata a haɗa jona da baƙar fata tare da mummunan sandar motar bas ɗin DC bi da bi, kuma a tuntuɓi saitin abubuwa 3-waya Yi rikodin kewaye da mai juyawa daban Kuma yi rikodin ƙimar juriya. Dabi'u uku na juriya da aka nuna a lokacin ƙarshe daidai suke, kuma ƙimar da aka nuna ta ƙarshe ita ce OL. Yi amfani da wannan hanyar don haɗa binciken baƙar fata zuwa tabbatacciyar sandar motar DC, kuma sakamakon ƙididdigar daidai yake, yana nuna cewa mai juyawa al'ada ce. In ba haka ba, yana nuna cewa akwai matsala tare da IGBT na inverter module na inverter, kuma ana buƙatar maye gurbin IGBT module ɗin.
2. game da tasirin motsawar mai juyawar
Za'a iya yin gwajin tsayayyen ne kawai bayan duk gwaje-gwaje tsayayyu sun zama na al'ada. A gefe guda, kafin samarda wuta a kan inverter, ya zama dole a bincika ko karfin shigar da karfin karfin inverter iri daya ne; a gefe guda, ya zama dole a bincika ko kowane tashar da darajan suna kwance kuma ko haɗin haɗin na al'ada ne. Bayan inverter ya kunna wuta, sai a fara gano kuskuren, sai a tantance musababbin da kuma nau'in kuskuren daidai da lambar laifin; abu na biyu, bincika ko sigogin da aka saita da sifofin ɗimbin nauyi iri ɗaya ne. Idan inverter ba a haɗa shi da kayan ba kuma baya cikin aiki, da fatan za a auna ko ƙarfin wutar fitarwa ta waya uku ya daidaita.
