Momwe mungayesere nthaka ndi multimeter
Zamkatimu
Kodi nyali zanu zikuthwanima? Kodi makina anu ochapira amachedwa, sakugwira ntchito, kapena sakugwira ntchito konse?
Ngati yankho lanu ku mafunso awa ndi inde, ndiye kuti kugwirizana kwapansi m'nyumba mwanu ndi chifukwa chotheka.
Kuyika m'nyumba mwanu ndi chimodzi mwazinthu zofunika kwambiri zomwe muyenera kuzisamalira.
Kugwiritsa ntchito moyenera zida zanu zamagetsi sikofunikira kokha, koma kumatha kukhala kusiyana pakati pa moyo ndi imfa.
Mu bukhuli, mupeza zonse zomwe muyenera kudziwa zokhudza malo oyesera.
Tiyeni tiyambe.
Kodi grounding ndi chiyani?
Kuyika pansi, komwe kumatchedwanso grounding, ndi njira yodzitetezera polumikizira magetsi yomwe imachepetsa kuopsa kapena zotsatira za kugwedezeka kwa magetsi.
Ndi nthaka yoyenera, magetsi otuluka m'malo ogulitsira kapena zipangizo zamagetsi amapita pansi, kumene amatayika.
Popanda kuyika pansi, magetsi awa amamanga m'malo ogulitsira kapena zitsulo za chipangizocho ndipo angapangitse kuti zida zisagwire ntchito kapena kugwira ntchito bwino.
Munthu akakumana ndi zitsulo zokhala ndi magetsi kapena mawaya otuluka amakhala pachiwopsezo cha kugunda kwamagetsi koopsa.
Kuyika pansi kumawongolera magetsi ochulukirapo awa pansi ndikuletsa zonsezi.
Tsopano mwamvetsa chifukwa chake kuli kofunika kuti malo ogulitsira m'nyumba mwanu akhale okhazikika bwino.
Multimeter ndi chida chothetsera mavuto amagetsi, ndipo ndiyabwino kuyesa malo omwe mumagulitsira khoma.
Momwe mungayesere nthaka ndi multimeter
Ikani chowongolera chofiyira cha multimeter mu doko lotulutsa mphamvu, ikani kutsogolo kwakuda mu doko losalowerera ndale, ndikulemba zomwe zikuwerengedwa. Sungani kafukufuku wofiyira mu doko logwira ntchito ndikuyika kafukufuku wakuda pa doko lapansi. Ngati kuwerenga sikuli kofanana ndi kuyesa kwam'mbuyomu, nyumba yanu ilibe kulumikizana koyenera..
Adzafotokozedwa motsatira.
- Khwerero 1. Ikani ma probes mu multimeter
Mukamayang'ana malo ogulitsa kunyumba, muyenera kusamala momwe mumalumikizira ma probes ku multimeter.
Ikani chowongolera chofiira (chabwino) padoko la multimeter cholembedwa kuti "Ω, V kapena +" ndi chiwongolero chakuda (choyipa) padoko la multimeter lolembedwa "COM kapena -".
Popeza mudzakhala mukuyesa mawaya otentha, onetsetsani kuti zotsogolera zanu zili bwino ndipo simudzasakaniza zotsogolera pa multimeter kuti musawononge.
- Khwerero 2: Khazikitsani ma multimeter kukhala magetsi a AC
Zida zanu zimayenda pa alternating current (AC) ndipo monga momwe zimayembekezeredwa, uwu ndi mtundu wamagetsi omwe mumatuluka.
Tsopano mumangotembenuza kuyimba kwa ma multimeter kukhala ma voteji a AC, omwe amadziwika kuti "VAC" kapena "V~".
Izi zimakupatsani kuwerenga kolondola kwambiri.
- Khwerero 3: Yesani voteji pakati pa madoko ogwira ntchito ndi osalowerera ndale
Ikani chiwongolero chofiira (chabwino) cha multimeter mu doko lotulutsa mphamvu ndikulozera wakuda (woyipa) kulowa padoko losalowerera ndale.
Doko lomwe limagwira ntchito nthawi zambiri limakhala laling'ono pa madoko awiriwo, pomwe doko lopanda ndale ndi lalitali kwambiri pa awiriwo.
Komano, doko lamtunda limapangidwa ngati "U".
Madoko pamakoma ena amatha kupangidwa mosiyanasiyana, pomwe doko logwira ntchito nthawi zambiri limakhala kumanja, doko lopanda ndale limakhala kumanzere, ndipo doko lapansi lili pamwamba.
Kuwerengera kwamagetsi pakati pa waya wanu wamoyo ndi kusalowerera ndale ndikofunikira kuti kufananitsako kuchitike mtsogolo.
Tengani miyeso yanu ndikupita ku sitepe yotsatira.
- Khwerero 4: Yesani voteji pakati pa madoko amoyo ndi pansi
Tsopano chotsani kafukufuku wanu wakuda pa doko lotulutsa ndale ndikulilumikiza padoko lapansi.
Dziwani kuti kafukufuku wanu wofiyira amakhalabe padoko logwira ntchito.
Mudzaonetsetsanso kuti ma probe akulumikizana ndi zitsulo zomwe zili mkati mwazitsulo kuti multimeter yanu ikhale ndi kuwerenga.
Tengani miyeso yanu ndikupita ku sitepe yotsatira.
- Khwerero 5: Yesani voteji pakati pa madoko osalowerera ndale ndi pansi
Muyezo wowonjezera womwe mukufuna kutenga ndikuwerengera kwamagetsi pakati pa madoko anu osalowerera ndale ndi pansi.
Ikani kafukufuku wofiyira mu doko lotulutsa zandale, ikani kafukufuku wakuda mu doko la pansi ndikuyesa.
- Gawo 6: Kuunikira zotsatira
Ino ndi nthawi yofananiza ndipo mudzakhala mukupanga zambiri.
- Choyamba, ngati mtunda wapakati pa madoko anu ogwirira ntchito ndi pansi uli pafupi ndi ziro (0), nyumba yanu ikhoza kukhala yosakhazikika bwino.
- Kupitilira apo, ngati muyeso pakati pa madoko anu okhazikika komanso osalowerera ndale sikuli mkati mwa 5V kapena mofanana ndi muyeso wapakati pa madoko anu omwe akugwira ntchito ndi pansi, nyumba yanu ikhoza kukhala yosakhazikika bwino. Izi zikutanthauza kuti pamaso pa nthaka, ngati mayeso a gawo ndi osalowerera apeza 120V, kuyesa kwa gawo ndi pansi kumayembekezeredwa kuti azindikire 115V mpaka 125V.
- Kungoti zonsezi zitatsimikiziridwa, mupanganso kufananitsa kumodzi. Izi ndi zofunika kufufuza mlingo wa kutayikira pansi ndi kudziwa khalidwe lake.
Pezani kusiyana pakati pa kuyesa kwamoyo ndi kusalowerera ndale ndi kuyesa kwamoyo ndi pansi.
Onjezani izi pamayeso osalowerera ndale komanso apansi.
Ngati kuwonjezera kwawo kupitilira 2V, ndiye kuti kulumikizana kwanu sikuli bwino ndipo kuyenera kuyang'aniridwa.
Muvidiyoyi tikufotokoza ndondomeko yonseyi:
Chiyeso china chomwe mungachite ndichokhudzana ndi kusagwirizana kwapadziko lapansi kwa kulumikizana kwanu ndi dziko lapansi.
Komabe, uwu ndi mutu wosiyana kwambiri, ndipo mutha kuyang'ana mwatsatanetsatane nkhani yathu yoyesa kukana kwa nthaka ndi multimeter.
Malo oyesera babu
Kuti muyang'ane pansi panyumba yanu ndi babu, mufunika soketi ya mpira ndi zingwe zingapo.
Yatsani babu ndikuyikanso zingwe pa soketi ya mpira.
Tsopano onetsetsani kuti nsonga zina za zingwezo ndi zosachepera 3cm (palibe zotsekera) ndikuzilumikiza m'madoko amoyo komanso osalowererapo.
Ngati kuwala sikuyatsa, ndiye kuti nyumba yanu sinazike bwino.
Monga mukuwonera, mayesowa sakhala olongosoka komanso olondola monga kuyesa ndi ma multimeter.
Pomaliza
Kuwona maziko m'nyumba mwanu ndi njira yosavuta.
Zomwe muyenera kuchita ndikutenga miyeso pakati pa makoma osiyanasiyana ndikuyerekeza miyesoyo wina ndi mzake.
Ngati miyezo iyi siyikufanana kapena kukhala m'mizere ina, malo a nyumba yanu ndi olakwika.
Mafunso ofunsidwa kawirikawiri
Kodi mungadziwe bwanji ngati muli ndi waya woyipa?
Chizindikiro chimodzi chodziwika bwino cha kusakhazikika bwino m'nyumba ndi nyali zakuda kapena zothwanima. Nthawi zina, zida zamagetsi zomwe zili m'nyumba mwanu sizingayatse kapena sizingagwire bwino ntchito.
Kodi waya wapansi uyenera kukhala ndi ma ohm angati?
Zikuyembekezeka kuti kukana kwanu kudzakhala kosaposa 5 ohms, pomwe mtengo wabwino kwambiri ndi ziro (0) ohms. Kuyandikira kwa mtengo wotsutsa ndi zero, ndikomwe kumayambira bwino.
Kodi waya wosasunthika angachite chiyani?
Kuyika pansi koyipa kumapangitsa kuti mababu anu aziwala kapena kuthwanima. Zimapangitsanso kuti zipangizo zamagetsi zilephereke kapena kuleka kugwira ntchito chifukwa palibe mphamvu zokwanira zoyendetsa.
