Yadda ake duba fis ɗin thermal tare da multimeter
Abubuwa
Fuskokin thermal sau da yawa suna busawa saboda hauhawar wutar lantarki kuma wani lokacin saboda toshewa. Ba za ku iya kallon fuse kawai ku ga idan an busa ba, kuna buƙatar yin gwajin ci gaba.
Duban ci gaba yana ƙayyade kasancewar ci gaba da hanyar lantarki. Idan fuse thermal yana da mutunci, to yana aiki, kuma idan ba haka ba, to yana da kuskure kuma yana buƙatar maye gurbinsa.
Wannan labarin zai bayyana ƴan matakai masu sauƙi don bincika idan fuse yana da da'irar ci gaba ko a'a. Don yin wannan, kuna buƙatar multimeter, zai fi dacewa multimeter dijital.
Don gwaji, kuna buƙatar bi waɗannan matakan:
1. Nemo kuma cire fuse daga kayan aikin ku,
2. Bude fuse thermal ba tare da lalata shi ko cutar da kanku ba, kuma a ƙarshe
3. Saita multimeter zuwa yanayin da ya dace don gwada ci gaba.
Kayan aiki da ake buƙata
Kuna buƙatar kayan aiki masu zuwa don gwada ci gaban fuse:
- Multimeter na dijital ko analog mai aiki
- Thermal fiusi daga na'ura mara kyau
- Haɗin wayoyi ko na'urori masu auna firikwensin
- Kayan lantarki
- Screwdrivers masu girma dabam
Yadda ake duba fuse tare da multimeter
Bi matakan da ke ƙasa don fahimtar abin da kuke buƙatar yi don gano ko fis ɗin ku yana cikin yanayin da ya dace.
- Wuri da kau da thermal fiusi: Thermal fuses suna samuwa a cikin siffofi da girma dabam dabam. Dukkansu suna da ayyuka na ciki iri ɗaya waɗanda ke ayyana ayyukansu. Misali, idan kuna amfani da na'urar bushewa, za ku fara da cire duk sukurori da neman fiusi na thermal. Sa'an nan kuma shunt da wayoyi da kuma cire fuse. Takaddun fis ɗin suna taimaka mana don tabbatar da cewa ba a haɗa na'urar zuwa tushen wuta ba. Wannan yana taimaka mana mu guji girgiza wutar lantarki. Yawancin fuses an gyara su cikin amintacciyar hanyar shiga. Ana shigar da su a bayan nuni ko kwamitin sarrafawa (misali, a cikin tanda microwave ko injin wanki). A cikin firji, fuses na thermal suna cikin injin daskarewa. Yana bayan murfin evaporator saboda dumama. (1)
- Yadda ake buɗe fis ɗin thermal ba tare da lahanta shi ko cutar da kanku ba: Don buɗe fuse, cire haɗin wayoyi daga tashoshi. Sa'an nan kuma yi amfani da screwdriver don cire sukurori da ke riƙe da fis ɗin thermal a wurin.
- Yadda ake Shirya Multimeter don Gwajin Ci gabaA: Kafin ka yanke shawarar ko maye gurbin tsohon fiusi ko a'a, kana buƙatar yin gwajin ci gaba. Kuna buƙatar multimeter don wannan aikin. Wani lokaci tashoshin fuse suna toshewa. Don haka, ƙila kuna buƙatar buɗe toshewar ta hanyar cire toshewar ko datti. Sa'an nan kuma a hankali shafa su da wani karfe kafin yin gwajin ci gaba. (2)
Don kunna multimeter, kunna bugun kiran kewayon zuwa mafi ƙarancin juriya a cikin ohms. Bayan haka, daidaita mita ta hanyar haɗa na'urori masu auna firikwensin tare. Saita allura zuwa sifili (don analog multimeter). Don multimeter na dijital, juya bugun kiran zuwa mafi ƙarancin juriya. Sannan a yi amfani da bincike ɗaya don taɓa ɗaya daga cikin tashoshin kayan aikin, ɗayan kuma don taɓa ɗayan tashar.
Idan karatun zero ohms, fuse yana da mutunci. Idan hannun baya motsawa (don analog) ko kuma idan nunin bai canza sosai ba (don dijital), to babu ci gaba. Rashin ci gaba yana nufin an busa fis ɗin kuma yana buƙatar maye gurbinsa.
Maye gurbin fis mai lahani da shawarwarin kulawa
Don maye gurbin fis ɗin thermal, juya hanyar cirewa kamar yadda ke sama. Don rage haɗarin busa fis, yi amfani da masu sarrafa wutar lantarki don jinkirta wuta ko ƙarfin lantarki. Don rage clogging, wajibi ne don rufe fuse kuma cika ramukan da ke cikin na'urar. A ƙarshe, yi amfani da fiusi na dindindin.
