Ungahlola kanjani i-fuse eshisayo nge-multimeter

Amafuse ashisayo avame ukuvunguza ngenxa yokwanda kwamandla futhi ngezinye izikhathi ngenxa yokuvala. Awukwazi ukuvele ubheke i-fuse ubone ukuthi ishaywe umoya, udinga ukwenza ukuhlolwa kokuqhubeka.

Ukuhlola ukuqhubeka kunquma ukuba khona kwendlela kagesi eqhubekayo. Uma i-fuse eshisayo inobuqotho, khona-ke iyasebenza, futhi uma kungenjalo, khona-ke inephutha futhi idinga ukushintshwa.

Lesi sihloko sizochaza izinyathelo ezimbalwa ezilula zokuhlola ukuthi i-fuse inomjikelezo wokuqhubeka noma cha. Ukuze wenze lokhu, uzodinga i-multimeter, okungcono i-multimeter yedijithali.

Ukuze uhlole, udinga ukulandela lezi zinyathelo:

1. Thola futhi ukhiphe i-fuse kumshini wakho,

2. Vula i-fuse eshisayo ngaphandle kokuyilimaza noma ukuzilimaza, futhi ekugcineni

3. Setha i-multimeter ibe yimodi efanele ukuze uhlole ukuqhubeka.

Amathuluzi adingekayo

Uzodinga okokusebenza okulandelayo ukuze uhlole ukuqhubeka kwe-fuse:

• Idijithali esebenzayo noma i-analog multimeter
• I-thermal fuse evela entweni engasebenzi kahle
• Izintambo ezixhumayo noma izinzwa
• Into esebenza ngogesi
• Izikulufa ezinosayizi abahlukene

Ungahlola kanjani i-fuse nge-multimeter

Landela lezi zinyathelo ezingezansi ukuze uqonde ukuthi yini okudingeka uyenze ukuze uthole ukuthi i-fuse yakho isesimweni esifanele yini. 

1. Indawo kanye nokususwa kwe-fuse eshisayo: Amafuse ashisayo atholakala ngezindlela ezihlukahlukene nosayizi. Wonke anemisebenzi efanayo yangaphakathi echaza ukusebenza kwawo. Isibonelo, uma usebenzisa isomisi, uzoqala ngokususa zonke izikulufu bese ubheka i-thermal fuse. Bese uvala izintambo bese ususa i-fuse. Amalebula e-fuse asisiza ukuthi senze isiqiniseko sokuthi into esetshenziswayo ayixhunyiwe kumthombo wamandla. Lokhu kusisiza ukuba sigweme ukushaqeka kukagesi. Amafuse amaningi aqiniswe ngokuvikelekile kuphaneli yokufinyelela. Zifakwe ngemuva kwesibonisi noma iphaneli yokulawula (isibonelo, kuhhavini ye-microwave noma kumshini wokugeza izitsha). Eziqandisini, amafuse ashisayo akhona efrijini. Ingemuva kwekhava ye-evaporator ngenxa ye-heater. (1)
2. Indlela yokuvula i-fuse eshisayo ngaphandle kokuyilimaza noma ukuzilimaza: Ukuze uvule i-fuse, nqamula izintambo kumatheminali. Bese usebenzisa i-screwdriver ukuze ususe izikulufu ezibambe i-thermal fuse endaweni.
3. Uyilungiselela Kanjani I-Multimeter Yokuhlolwa OkuqhubekayoIMP: Ngaphambi kokuthi unqume ukuthi uzoshintsha i-fuse endala noma cha, udinga ukwenza ukuhlolwa kokuqhubeka. Uzodinga i-multimeter kulo msebenzi. Kwesinye isikhathi amatheminali e-fuse ayavaleka. Ngakho-ke, kungase kudingeke ukuthi uvule ukuvinjelwa ngokususa ama-blockages noma ukungcola. Bese uzihlikihle ngobumnene ngento yensimbi ngaphambi kokwenza ukuhlolwa kokuqhubeka. (2)

   Ukuze ushune i-multimeter, vula ukudayela kobubanzi kube inani eliphansi lokumelana nama-ohms. Ngemva kwalokho, linganisa amamitha ngokuxhuma izinzwa ndawonye. Setha inaliti ku-zero (ye-multimeter ye-analog). Ukuze uthole i-multimeter yedijithali, vula ukudayela kube kunani elincane lokumelana. Bese usebenzisa i-probe eyodwa ukuze uthinte enye yamatheminali ensimbi bese enye i-probe ukuthinta enye itheminali.

   Uma ukufundwa kunguziro ohms, i-fuse inobuqotho. Uma isandla singanyakazi (ku-analog) noma uma isibonisi singashintshi kakhulu (kwedijithali), akukho ukuqhubeka. Ukuntuleka kokuqhubeka kusho ukuthi i-fuse iyashaywa futhi idinga ukushintshwa.

Ukushintsha i-fuse enesici namathiphu okulungisa

Ukuze ungene esikhundleni se-thermal fuse, hlehlisa inqubo yokususa njengenhla. Ukuze unciphise ingozi yokufutha ama-fuse, sebenzisa izilawuli ze-voltage ukuze ubambezele amandla noma i-voltage. Ukuze unciphise ukuvala, kuyadingeka ukuvala i-fuse futhi ugcwalise izimbobo kudivayisi. Ekugcineni, sebenzisa i-fuse ehlala njalo.

Bheka ezinye zezihloko zethu ngezansi.

• Uphawu lokuqhubeka lwamamitha amaningi
• Ungawafunda kanjani ama-ohms ku-multimeter
• Ungayihlola kanjani i-capacitor nge-multimeter
