Maitiro ekutarisa iyo thermal fuse ine multimeter

Mafusi anopisa anowanzo vhuvhuta nekuda kwekukwira kwesimba uye dzimwe nguva nekuda kwekuvhara. Iwe haugone kungotarisa fuse uye kuona kana yakavhuvhuta, iwe unofanirwa kuita yekuenderera bvunzo.

Kuenderera mberi kwekuongorora kunotarisa kuvapo kwenzira inopfuurira yemagetsi. Kana iyo fuse inopisa ine kutendeseka, saka iri kushanda, uye kana isiri, saka yakashata uye inoda kutsiviwa.

Ichi chinyorwa chinotsanangura matanho mashoma akareruka ekutarisa kana fuse ine kuenderera kwedunhu kana kwete. Kuti uite izvi, iwe uchada multimeter, zvichida digital multimeter.

Kuti uedze, unofanirwa kutevera matanho aya:

1. Tsvaga uye bvisa fuse mumudziyo wako,

2. Vhura fuse inopisa pasina kukuvadza kana kukuvadza iwe pachako, uye pakupedzisira

3. Isa iyo multimeter kune iyo chaiyo mode kuti uedze kuenderera mberi.

Zvishandiso zvinodiwa

Iwe unozoda zvinotevera zvishandiso kuti uedze kuenderera kwefuse:

• Inoshanda dhijitari kana analog multimeter
• Thermal fuse kubva kune chakashata
• Kubatanidza waya kana masensa
• Chishandiso chemagetsi
• Screwdrivers ehukuru hwakasiyana

Nzira yekutarisa fuse ne multimeter

Tevedza matanho ari pasi apa kuti unzwisise zvaunofanira kuita kuti uone kana fuse yako iri muchimiro chakakodzera. 

1. Nzvimbo uye kubviswa kweiyo thermal fuse: Thermal fuse inowanikwa mune akasiyana maumbirwo uye saizi. Vose vane mabasa akafanana emukati anotsanangura kushanda kwavo. Semuenzaniso, kana uri kushandisa dryer, iwe unotanga nekubvisa ese screws uye kutsvaga iyo inopisa fuse. Zvadaro vhara waya uye bvisa fuse. Mafuse labels anotibatsira kuona kuti mudziyo hauna kubatana nemagetsi. Izvi zvinotibatsira kuti tisarohwa nemagetsi. Mafusi mazhinji akachengetedzwa zvakachengeteka mupaneru yekupinda. Iwo akaiswa kuseri kwechiratidziro kana control panel (somuenzaniso, mune microwave oveni kana dishwasher). Mumafiriji, mafizi anopisa aripo mufiriji. Iri kuseri kwevhavha ye evaporator nekuda kwehita. (1)
2. Maitiro ekuvhura iyo thermal fuse pasina kuikuvadza kana kuzvikuvadza iwe pachako: Kuti uvhure fuse, bvisa waya kubva kumaterminals. Zvadaro shandisa screwdriver kubvisa screws akabata thermal fuse panzvimbo.
3. Maitiro Ekugadzirira Multimeter Yekuenderera MuedzoA: Usati wasarudza kutsiva fuse yekare kana kuti kwete, unofanirwa kuita bvunzo yekuenderera mberi. Iwe uchada multimeter yebasa iri. Dzimwe nguva fuse terminals dzinovharika. Naizvozvo, ungangoda kusunungura blockage nekubvisa blockages kana tsvina. Wozora zvinyoro nyoro nesimbi usati waita continuity test. (2)

   Kuti ugadzirise iyo multimeter, shandura dhayiri kune yakaderera kukosha kukosha muohms. Mushure meizvozvo, gadzirisa mamita nekubatanidza masensa pamwe chete. Isa tsono kusvika zero (ye analog multimeter). Kune yedhijitari multimeter, shandura dial kune kushoma kuramba kukosha. Wobva washandisa imwe probe kubata imwe yematerminal echiridzwa uye imwe probe kubata imwe terminal.

   Kana kuverenga kuri zero ohms, fuse ine kutendeseka. Kana ruoko rusingafambi (kweanalog) kana kana chiratidziro chisingachinji zvakanyanya (yedhijitari), saka hapana kuenderera. Kushaikwa kwekuenderera kunoreva kuti fuse inofuridzwa uye inoda kutsiviwa.

Kutsiva fuse yakaremara uye mazano ekugadzirisa

Kuti utsive fuse inopisa, shandura nzira yekubvisa sepamusoro. Kuti uderedze njodzi yekufuridza fuse, shandisa voltage regulators kunonoka simba kana voltage. Kuti uderedze kuvhara, zvakakosha kuvhara fuse uye kuzadza maburi muchigadzirwa. Pakupedzisira, shandisa fuse isingagumi.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

• Multimeter kuenderera chiratidzo
• Nzira yekuverenga ohms pane multimeter
• Nzira yekuedza capacitor ne multimeter
