Indlela Yokuhlola I-Relay nge-Multimeter (Isinyathelo Ngesinyathelo Umhlahlandlela)

Ama-relay angenye yezingxenye zikagesi ezibaluleke kakhulu ezimotweni, izinhlelo ezishintshayo zasekhaya nezinye izinhlelo zokusebenza lapho ukushintshwa okusheshayo kwamasekhethi anamandla aphezulu kuyadingeka. Kodwa-ke, njengamadivaysi e-electromechanical, ama-relay angaphansi kokuguga futhi angahluleka noma nini. Ngakho-ke, kubaluleke kakhulu ukuhlola ama-relay akho njalo ukuze uqinisekise ukuthi asebenza kahle kakhulu.

Enye yezindlela ezihlukahlukene zokuhlola i-relay multimeter yedijithali. Ake ngikuhambise ezinyathelweni ukuze uqalise ukuhlola i-relay nge-multimeter.

Mayelana ne-relay

I-relay iyidivayisi yokulawula kagesi enesistimu yokulawula (i-input circuit) kanye nesistimu elawulwayo (i-output circuit), evame ukutholakala kumasekhethi okulawula. Isebenza njengomlawuli wesekethe, isekethe yokuphepha kanye nesiguquli. I-relay ifaka ukusabela okusheshayo, ukusebenza okuzinzile, impilo ende yesevisi kanye nosayizi omncane. (1)

Ama-relay ngokuvamile asetshenziselwa ukulawula ukujikeleza kwamanje okuphezulu kusuka kusekethe yamanje ephansi. Bakuzo zonke izimoto. Ama-relay asebenza njengamaswishi, okuvumela isekethe ye-amperage ephansi ukuthi ivule noma ivale isekethe ephezulu ye-amperage. Ngaphezu kwalokho, i-relay ingaphinda ilawule amasistimu amaningi ngesikhathi esisodwa, njengokukhanyisa izibani uma ama-wiper evuliwe, noma ukwelula uthi uma umsakazo uvuliwe.

Okudingayo Lapho Uhlola I-Relay

Ukuhlola ukudluliselwa kwemoto yakho kuyinqubo elula engadingi ukusetshenziswa kwekhithi ephelele. Ukuze uqale ukuhlola i-relay, uzodinga izinto ezilandelayo:

Amathuluzi: 

• Ukukhanya okuphezulu kokuhlolwa kwe-impedance
• I-ohmmeter, evame ukubizwa ngokuthi i-digital multimeter (DMM).
• Imanuwali Yesevisi Yezimoto (uyazikhethela kodwa iyanconywa kakhulu)

Izingxenye ezisele:            

• Ukushintshwa Okufanelekile Kwe-Relay
• i-jumper wire

Edluliselwe Test Izinyathelo

Isinyathelo 1: Thola i-relay 

Kuye ngokuthi ilawula ini, ungathola i-relay ngaphansi kwedeshi noma endaweni yenjini. Hlola isahluko sikagesi semanuwali yakho yesevisi kanye nomdwebo wezintambo uma ungaqiniseki ngokubekwa.

Isinyathelo sesi-2: Hlola futhi uhlanze izixhumi

Uma usuyitholile i-relay, isuse. Bese uhlanza futhi uhlole izixhumi ngenkathi lokhu kudluliswa kuvaliwe. Ukushintsha i-relay eyinhloko ngokufaka okunye okufanelekile kuyindlela esheshayo nelula yokuyihlola.

Isinyathelo sesi-3: Thola i-multimeter

Setha i-multimeter yakho kumodi yokulinganisa ukumelana. Bese ukala ukumelana ngokuthinta amakhoyili. Ikhoyili evamile inokumelana kwe-40 ohms kuya ku-120 ohms. Ukusonteka kwekhoyili ye-solenoid embi kubonisa ukuthi i-relay ayikho ebangeni noma ivuliwe futhi sekuyisikhathi sokuyishintsha. Bese ugcine i-multimeter ikumodi yokumelana noma yokuqhubeka. Ngemuva kwalokho, xhuma othintana nabo abashintshile kumkhondo. Kufanele ibonise ivuliwe noma i-OL uma kuwukudluliswa okujwayelekile okuvulekile.

Isinyathelo sesi-4: Vula ikhoyili kazibuthe 

Ngebhethri engu-9-12V koxhumana nabo, sebenzisa amandla kule khoyili kazibuthe. Lapho ikhoyili inika amandla futhi ivala iswishi, i-relay kufanele yenze ukuchofoza okuzwakalayo. Ku-4-pin relay, i-polarity ayibalulekile, kodwa ekusakazweni kwe-diode ibalulekile.

Isinyathelo sesi-5: Xhuma isibani sokuhlola 

Xhuma ibhethri iphozithivu kwelinye lamatheminali okushintsha lapho ikhoyili isasebenza. Bese uxhuma isibani sokuhlola phakathi komhlaba kanye netheminali yokushintsha. Isibani sokulawula kufanele sidle ugesi futhi sikhanyise. Bese ukhipha i-jumper evumayo ebhethrini. Isibani sokulawula kufanele sicime ngemva kwemizuzwana embalwa.

Isinyathelo sesi-6: Ukuhlola i-Voltage Relay

Ekushintsheni, hlola i-voltage edluliselwe. Amaphoyinti okuxhumana amabi angaholela ekulahlekelweni kwamandla kagesi. Susa ukukhanya kokuhlola bese ushintsha i-multimeter ibe yi-DC voltage. Bese uxhuma izintambo kuzixhumi zesibani sokuhlola noma ushintshe abathintwayo. Ukufundwa kufanele kufane nomthamo webhethri.

Isinyathelo sesi-7: Hlola iswishi

Hlola ukumelana okulungile ekushintsheni. I-jumper eqondile kufanele inqanyulwe futhi ikhoyili ye-solenoid kufanele inikezwe amandla. Bese ukala ukumelana nabo bonke abathintwayo beshintshi nge-multimeter ebekwe ku-ohms. Ngokuvamile, i-relay evulekile kufanele ilinganisele eduze kokumelana neqanda lapho ivuliwe, kuyilapho i-relay evalekile kufanele ilinganise ukuvuleka noma i-OL uma ivuliwe.

I-Relay Testing Pro Amathiphu

Lapho usebenza ngama-relay, kutuswa ukukhumbula okulandelayo:

Gwema ukuxuba nokufanisa 

Uma unokudlulisela okubi okudinga ukushintshwa, akuwona umqondo omuhle ukuxuba nokufanisa ama-relay asuka kwezinye izingxenye zemoto noma umgqomo kadoti ongahleliwe egalaji lakho. Lokhu kungabangela ukujikeleza okufushane noma ukuhamba kwamandla okuzolimaza isistimu kagesi yemoto yakho. (2)

Phatha ngokucophelela

Kubaluleke kakhulu ukuqaphela ukuthi ungawisi i-relay. Uma izingxenye zangaphakathi ze-relay zicekelwa phansi, izintambo zingashisa noma zincibilike. Gwema futhi ukuphazamisa ukusebenza kwe-relay.

Ziqhelelanise namagesi avuthayo 

Ungawasebenzisi ama-relay nanoma yini edinga ugesi ezindaweni lapho kukhona amagesi aqhumayo noma avuthayo njengophethiloli noma amanye amafutha.

Funda izincwadi zokulungisa

Hlola imanuwali yesevisi yemoto yakho (hhayi imanuwali yomnikazi wakho) ukuze uhlonze futhi uqonde isistimu yezintambo ne-relay, ngisho noma usuvele ungumlungisi wegaraji onolwazi.

Hlela amathuluzi akho 

Lungiselela wonke amathuluzi adingekayo kusengaphambili futhi ubeke yonke into endaweni yayo. Lokhu kuzokongela isikhathi esibalulekile futhi kukuvumela ukuthi ugxile emsebenzini wamanje ngaphandle kokubheka amathuluzi phakathi nenqubo.

Imibuzo evame ukubuzwa 

Kubiza malini ukufaka esikhundleni se-relay?

I-relay ingabiza noma yikuphi ukusuka ku-$5 kuya kumakhulu ambalwa amadola, kuye ngokuthi ilawula ini. Okulandelayo ama-ohmmeters, abiza ngaphansi kuka-$20 futhi eza ngezinhlobonhlobo zomumo nosayizi. Okwesibili, amalambu okuhlola ama-impedance aphezulu abiza kancane, alinganiselwa ku-$20 kuya ku-$40. Okokugcina, ama-jumpers awabizi, asuka ku-$2 kuya ku-$50 kuye ngobude bocingo.

Kwenzekani uma ngiziba inkinga engase ibe khona?

Ukuziba i-relay ehlulekile noma ukufaka noma iyiphi i-relay endala elingana kungabangela izinkinga ezinkulu. Uma i-relay ihluleka noma ifakwe ngokungalungile, ingashisa izintambo futhi ngokunokwenzeka iqale umlilo.

Anginayo i-ohmmeter noma ilambu lokuhlola. Ngingakwazi ukuhlola ukudluliselwa?

Cha. Unezinketho ezimbili kuphela uma uqinisekile ukuthi i-relay yakho iyinkinga, futhi kokubili kudinga ukusetshenziswa kwe-ohmmeter, ukukhanya kokuhlola, njll. Okokuqala, qaphela futhi esikhundleni sokudlulisela okuyinhloko ngamathuluzi adingekayo. Okwesibili, uma ungenawo amathuluzi wokuyihlola, ungaqasha umakhenikha ukuthi akuhlolele futhi akulungisele i-relay.

Ungaphinda uhlole eminye imihlahlandlela yokuhlola i-multimeter ngezansi;

• Ungayihlola kanjani i-capacitor nge-multimeter
• Ungayisebenzisa kanjani i-multimeter ukuhlola i-voltage yezintambo ezibukhoma
