Momwe mungadziwire waya wotentha popanda multimeter (njira 4)

Zamkatimu

Njira 1: gwiritsani ntchito chowunikira choyandikira
Njira 2: Gwiritsani ntchito screwdriver tester
Njira 3: gwiritsani ntchito babu ngati choyesa
- Momwe mungapangire chowunikira babu
- Kugwiritsa ntchito babu kuti muzindikire waya wamoyo
Njira 4: Kugwiritsa Ntchito Ma Code Amitundu

M'nkhaniyi, ndikuwonetsani momwe mungadziwire waya wotentha kapena wamoyo popanda kugwiritsa ntchito multimeter.

Multimeter imakulolani kuti muwone polarity ya mawaya; komabe, ngati mulibe, pali njira zina zochitira zomwezo. Monga katswiri wamagetsi wodalirika, ndaphunzira malangizo angapo ndi zidule pazaka zambiri kuti ndiwonetsere chingwe chamoyo popanda kugwiritsa ntchito multimeter, zomwe ndingakuphunzitseni. Njira zina zitha kukuthandizani chifukwa multimeter ikhoza kukhala yodula kwambiri pantchito yanu yanthawi imodzi.

Mwambiri, ngati mulibe multimeter, mutha kugwiritsa ntchito:

Voltage detector
Gwirani screwdriver
Lumikizani babu ku waya
Gwiritsani ntchito mtundu wokhazikika

Ndidzafotokoza mwatsatanetsatane pansipa.

Njira 1: gwiritsani ntchito chowunikira choyandikira

Ndikumvetsa kuti sitepeyi ingakhalenso yosapezeka ngati mulibe mwayi wogwiritsa ntchito zipangizo zamagetsi, momwemo ndingakuuzeni kuti mupite ku zitatu zotsatirazi.

Tsatirani njira zosavuta izi kuti muwone ngati waya watentha pogwiritsa ntchito chowunikira chamagetsi chomwe sichimalumikizana.

mwatsatane 1. Sungani chowunikira choyandikira pafupi ndi chinthu kapena kuyesa.

mwatsatane 2. Chizindikiro pa chowunikira chidzawunikira.

mwatsatane 3. Chojambulira chamagetsi chosalumikizana chimalira ngati pali voteji mu chinthu kapena waya.

mwatsatane 4. Mukuwona kuti mphamvu yomwe ikuyenda kudzera pawaya ndiyofunikira.

Malangizo: Osagwira chowunikira chamagetsi ndi ma probe, mawaya kapena gawo lina lililonse la tester panthawi ya mayeso. Izi zitha kuwononga choyesa ndikuchipangitsa kukhala chosatetezeka kugwiritsa ntchito.

Ma detectors ambiri amagwira ntchito poyesa kusintha kwa maginito mu chinthu chomwe chikuyesedwa. Ngati chinthucho chili ndi mphamvu, mphamvu ya maginito yomwe imapangitsa kuti magetsi aziyenda. Dera la detector lizizindikira panopo ndi beep.

Komabe, onetsetsani kuti chojambulira chamagetsi chosalumikizana chikugwira ntchito musanagwiritse ntchito. Izi ndizofunikira kwambiri chifukwa zotsatira zolakwika zimatha kubweretsa kuwonongeka kwakukulu ndi ngozi.

Njira 2: Gwiritsani ntchito screwdriver tester

Njira ina yodziwira ngati waya ndi wotentha kapena wamoyo ndikugwiritsa ntchito tester screwdriver.

KODI

Gawo 1: onetsani mawaya

Mutha kutsegula chivundikirocho kapena kuchotsa chilichonse chomwe chimapangitsa kuti mawaya asafike.

Mwinamwake mukufuna kuyang'ana mawaya kuseri kwa chosinthira; Pankhaniyi, masulani chivundikiro cha chosinthira kuti mupeze mawaya omwe mukufuna kuwona polarity.

Gawo 2: Pezani malo owonekera pawaya

Chifukwa mawaya ambiri ndi otsekedwa, mumafunika malo abwino komanso opanda kanthu kuti mugwire screwdriver ya tester.

Ngati simungapeze malo opanda kanthu pawaya momwe mungayikire screwdriver ya tester, ndikupangira kuvula waya. Koma choyamba, muyenera kuzimitsa mphamvu ku chipangizo chomwe mukugwira nacho pa switch panel. Osavula mawaya amoyo popanda chidziwitso choyenera. Mutha kugwidwa ndi magetsi.

Tsatirani izi:

Pezani waya stripper kapena pliers insulated.
Kokani mawaya omwe mukufuna kuti muwone polarity
Ikani mawaya pafupifupi theka la inchi m'nsagwada za chopingira mawaya kapena pliers ndikudula chotchingacho.
Tsopano mutha kubwezeretsa mphamvu ndikupitiriza kuyesa.

Khwerero 3: Gwirani screwdriver ya tester ku mawaya opanda kanthu.

Musanayambe kuyesa kwenikweni, onetsetsani kuti screwdriver ya tester yanu ndi yotetezedwa mokwanira kuti musapewe ngozi.

Kenako, gwirani insulated mbali ndi kukhudza poyera kapena anavula mawaya. Onetsetsani kuti screwdriver ya tester ikugwirizana bwino ndi mawaya.

Mofananamo, yang'anani babu ya neon pa screwdriver, ngati mutakhudza waya wotentha (ndi screwdriver tester), babu ya neon idzawunikira. Ngati wayayo alibe mphamvu (pansi kapena ndale), nyali ya neon siyaka. (1)

Chenjerani: Choyesa cholakwika choyesa screwdriver chingapereke zotsatira zolakwika. Chifukwa chake, onetsetsani kuti screwdriver yanu ikugwira ntchito. Apo ayi, mukhoza kukhala ndi dera lalifupi.

Njira 3: gwiritsani ntchito babu ngati choyesa

Choyamba, muyenera kupanga chowunikirachi kukhala chosavuta kugwiritsa ntchito. Mutha kugwiritsa ntchito kuyesa waya wotentha.

Momwe mungapangire chowunikira babu

mwatsatane 1. Chonde dziwani kuti babu iyenera kulumikizidwa kumapeto kwa waya. Chifukwa chake, babu iyenera kukhala ndi khosi lolumikizidwa ndi waya.

mwatsatane 2. Lumikizani mbali ina ya waya ku pulagi kuti mulowetse mu socket.

Chenjerani: osati vuto ngati mutagwirizanitsa waya wakuda, wofiira kapena wina aliyense ku babu; kuwala kwa tester kuyenera kukhudza waya wotentha ndikuwunikira - umu ndi momwe mumazindikirira waya wotentha.

Kugwiritsa ntchito babu kuti muzindikire waya wamoyo

mwatsatane 1. Dziwani nthaka - yobiriwira kapena yachikasu.

mwatsatane 2. Tengani choyesa ndikulumikiza mbali imodzi ku chingwe choyamba ndi china ku waya wapansi. Ngati kuwala kwabwera, ndi waya wotentha (chingwe choyamba). Ngati sichoncho, ikhoza kukhala waya wosalowerera.

mwatsatane 3. Yang'anani waya winayo ndikuwona momwe babu yamagetsi imagwirira ntchito.

mwatsatane 4. Onani waya wamoyo - womwe unayatsa babu. Iyi ndiye waya yanu yamoyo.

Njira 4: Kugwiritsa Ntchito Ma Code Amitundu

Iyi mwina ndiyo njira yosavuta yolozera chingwe chamoyo kapena chotentha pazida zamagetsi kapena zolumikizira mawaya; komabe, si zida zonse zamagetsi zomwe zili ndi mawaya ma code ofanana. Kuphatikiza apo, ma nambala amawaya amasiyana malinga ndi dziko ndi dera. Zotsatirazi ndizomwe zimakhala zamtundu wamtundu wa mawaya amagetsi.

M'malo ambiri opangira magetsi apanyumba, mawaya amakhodi ali motere (US National Electrical Code)

mawaya akuda - mawaya ali ndi mphamvu kapena mphamvu.
Mawaya obiriwira kapena opanda kanthu - tchulani mawaya oyambira ndi zolumikizira.
mawaya achikasu - imayimiranso kugwirizana kwapansi
mawaya oyera - ndi zingwe zopanda ndale.

Mtundu uwu wamtunduwu umakhazikitsidwa ndi National Electrical Code ndikusungidwa ndi National Fire Protection Association. (2)

Komabe, chifukwa cha kusiyana kwa mitundu yamitundu m'madera ena, simungadalire kwathunthu pamakhodi amtundu kuti muzindikire waya wamoyo. Komanso musagwire mawaya mpaka mutadziwa kuti ndi ati. Mwanjira imeneyi, muchepetse mwayi wa ngozi.

Onani zina mwazolemba zathu pansipa.
