Momwe mungayesere wowononga dera ndi multimeter
Zamkatimu
Chimodzi mwazinthu zofunika kwambiri zamagetsi pamagetsi amnyumba mwanu ndi ma circuit breakers.
Zida zazing'onozi zimakutetezani ku zoopsa zakupha komanso zida zanu zazikulu kuti zisawonongeke zomwe sizingawonongeke.
Tsopano, mwina mukukayikira kuti imodzi mwamagetsi anu ozungulira ndi yolakwika ndipo simukufuna kuyimbira wodziwa zamagetsi, kapena mukungofuna kudziwa momwe zida zamagetsi izi zimazindikirira zolakwika.
Mwanjira iliyonse, mwafika pamalo oyenera.
Kalozera wa sitepe ndi sitepe akuphunzitsani momwe mungayesere chowotcha chigawo ndi ma multimeter.
Tiyeni tiyambe.
Kodi circuit breaker ndi chiyani?
A circuit breaker ndi chabe chosinthira magetsi chomwe chimateteza dera kuti lisawonongeke ndi overcurrent.
Ichi ndi chosinthira chamagetsi, chomwe nthawi zambiri chimakhala mubokosi lamagetsi, chomwe chimasungidwa ndi screw kapena latch.
Overcurrent ndi pamene kuperekedwa kwa panopa kuposa mphamvu pazipita otetezeka chipangizo chimene cholinga chake, ndipo izi zimabweretsa ngozi yaikulu moto.
Wowononga dera amachotsa zolumikizana zake pamene izi zichitika, kuletsa kuyenda kwamakono ku chipangizocho.
Ngakhale kuti imagwira ntchito mofanana ndi fusesi, siyenera kusinthidwa itangowomba. Mumangoyikhazikitsanso ndikuyatsanso kuti ipitilize kugwira ntchito zake.
Komabe, zigawozi zimalephera pakapita nthawi ndipo kuteteza chipangizo chanu ndikofunikira kwambiri. Momwe mungadziwire wophwanya dera?
Momwe mungadziwire ngati wowononga dera ndi wolakwika
Pali zizindikiro zambiri zomwe zimasonyeza ngati woyendetsa dera wanu ali woipa.
Izi zimachokera ku fungo loyaka moto lochokera ku chophwanyira dera kapena gulu lamagetsi, kuwotcha zizindikiro pa chophwanyira dera lokha, kapena chophwanyira dera kukhala chotentha kwambiri mpaka kukhudza.
Chophwanyira chigawo cholakwika chimayendanso pafupipafupi ndipo sichikhala mumsewu wobwezeretsanso chikayatsidwa.
Zizindikiro zina siziwoneka pakuwunika kwakuthupi, ndipo apa ndipamene multimeter ndiyofunikira.
Zida zofunika kuyesa wowononga dera
Kuti muyesere circuit breaker mudzafunika
- multimeter
- Magolovesi osatetezedwa
- Seti ya akutali screwdrivers
Chida chokhala ndi insulated chidzakuthandizani kupewa kugwedezeka kwamagetsi.
Momwe mungayesere wowononga dera ndi multimeter
Kuti muyese zowononga ma circuit, ikani ma multimeter anu pa ohm setting, ikani chiwongolero chofiira pamagetsi amagetsi a circuit breaker, ndi chiwongolero chakuda chakuda pa terminal yomwe imagwirizanitsa ndi gulu. Ngati simukupeza kuwerengera kocheperako, chosokoneza chigawo ndi cholakwika ndipo chiyenera kusinthidwa..
Palinso njira zina zoyambira, ndipo mutha kuyesanso kuyesa kwamagetsi pamagetsi ozungulira. Zonsezi zidzafalikira.
- Yatsani chophwanyira dera
Kuyesa kukana kwa ophwanya ma circuit ndiyo njira yotetezeka kwambiri yoyezera zowononga madera chifukwa simusowa mphamvu yodutsamo kuti muzindikire molondola.
Pezani chosinthira chachikulu kapena chosinthira pagulu lamagetsi ndikuyitembenuzira pamalo "ozimitsa". Ichi nthawi zambiri chimakhala chosinthira chachikulu chomwe chimakhala pamwamba pabokosilo.
Izi zikachitika, pitirizani ndi ndondomeko zotsatirazi sitepe ndi sitepe.
- Khazikitsani ma multimeter anu kukhala ohm
Tembenuzirani kuyimba kwa ohm, komwe nthawi zambiri kumawonetsedwa ndi chizindikiro Omega (Ω).
Ngakhale mutha kugwiritsa ntchito njira yopitilira mita kuti muyese kupitiliza mkati mwa ophwanya dera, makonzedwe a Ohm amakupatsani zotsatira zenizeni. Izi ndichifukwa mumadziwanso kuchuluka kwa kukana mkati mwake.
- Chotsani chophwanyira dera kuchokera ku bokosi la breaker
Chosinthira nthawi zambiri chimalumikizidwa ndi bokosi lamagetsi lamagetsi mwina kudzera pa snap-in slot kapena kudzera pa screw. Lumikizani pagawo losinthira kuti muwonetse potengera china choyesa.
Pakadali pano, sunthani chosinthira chophwanyira ku malo "ozimitsa".
- Ikani ma multimeter otsogolera pa ma terminals ophwanyira dera
Tsopano ikani chiwongolero chowoneka bwino chofiira pa choyimira chamagetsi chosinthira ndi choyesa chakuda chakuda pa terminal pomwe mudadula chosinthira pabokosi losinthira.
- Voterani zotsatira
Sunthani chosinthira ku "pa" malo kuti mutsirize kuzungulira ndikuwona kuwerenga kwa mita.
Ngati mupeza zero (0) ohm kuwerenga, chosinthira chili bwino ndipo vuto likhoza kukhala ndi mawaya kapena bokosi losinthira.
Wowononga dera wabwino nthawi zambiri amakhala ndi kukana kwa 0.0001 ohm, koma ma multimeter sangathe kuyesa izi mwachindunji.
Kumbali ina, ngati mutapeza mtengo wa 0.01 ohms, ndiye kuti pali kukana kwambiri mkati mwa chosweka ndipo izi zikhoza kukhala vuto.
Kukaniza mkati mwa chosinthira pamwamba pa 0.0003 ohm kumaonedwa kuti ndi kokwera kwambiri.
Ndi akatswiri amagetsi okha omwe amakhala ndi chida chokhazikika chopangira miyeso yaying'ono iyi.
Komanso, kuwerengera kwa OL kumatanthauza kuti kusinthaku ndi koyipa ndipo kukufunika kusinthidwa. Izi zikuwonetsa kusowa kwa kupitiriza mkati mwa chipikacho.
Mutha kupeza malangizo onsewa muvidiyo yathu:
Kuyang'ana voteji mkati mwa circuit breaker
Njira inanso yomwe katswiri wamagetsi amagwiritsa ntchito kuti azindikire vuto ndi chophwanyira dera ndikuwunika mphamvu yamagetsi yomwe imagwiritsidwa ntchito.
Simukuyembekezera kuti chophwanyacho chigwire ntchito bwino popanda kukwanira pakali pano.
- Tengani Njira Zachitetezo
Kuti muyese voteji mkati mwa circuit breaker, muyenera kukhala ndi mphamvu yodutsamo. Inde, pali chiopsezo cha kugwedezeka kwa magetsi ndipo simukufuna kuvulazidwa.
Onetsetsani kuti mwavala magolovesi otetezedwa ndi mphira ndi magalasi ngati muli nawo. Onetsetsaninso kuti ma probe asakhudze wina ndi mzake panthawi yoyesera kuti asawononge chidacho.
- Khazikitsani ma multimeter kukhala magetsi a AC
Nyumba yanu imagwiritsa ntchito magetsi a AC ndipo ndalama zomwe zimagwiritsidwa ntchito zimasiyana kuchokera ku 120V mpaka 240V. 200 VAC ndi 600 VAC.
Khazikitsani ma multimeter ku AC voltage range yomwe ili yoyenera kwambiri kupewa kuwomba fuse ya multimeter.
Mtundu wa 200 ndi woyenera ngati nyumba yanu imagwiritsa ntchito volts 120, ndipo 600 ndi yoyenera ngati nyumba yanu imagwiritsa ntchito 240 volts. Mphamvu ya AC imawonetsedwa pa mita ngati "VAC" kapena "V~".
- Ikani kafukufuku wa multimeter pansi ndikuyambitsa terminal
Tsopano chosinthiracho chapatsidwa mphamvu, ikani kafukufuku wowoneka bwino wa ma multimeter pa cholumikizira magetsi ndikuyatsa cholumikiziracho poyika chofufuza choyipa pachitsulo chapafupi.
Malo awa ndi omwewo ngakhale mukugwiritsa ntchito chophwanyika chamitundu iwiri. Mukungoyesa mbali iliyonse payekha.
- Voterani zotsatira
Pakadali pano, mita ikuyembekezeka kuwonetsa kuwerengera kwamagetsi a AC a 120V mpaka 240V, kutengera kuchuluka komwe amagwiritsidwa ntchito kunyumba kwanu. Ngati simuwerenga bwino pamndandandawu, ndiye kuti magetsi a switch yanu ali ndi vuto.
Pomaliza
Mayeso awiri pa ophwanya dera lanu amathandizira kuzindikira zovuta zosiyanasiyana. Kuyesa kukana kumazindikira vuto ndi chosinthira chokha, pomwe kuyesa kwamagetsi kumathandizira kuzindikira vuto ndi magetsi.
Komabe, mayeso aliwonsewa ndi othandiza, ndipo kutsatira njira zomwe tazitchula pamwambapa motsatizana kumathandiza kusunga ndalama ndikupewa kuyimbira foni katswiri wamagetsi.
Mafunso ofunsidwa kawirikawiri
Kodi mungadziwe bwanji ngati wophwanya dera akufunika kusinthidwa?
Wowononga dera amasinthidwa ngati muwona kuwonongeka kwa thupi, monga zizindikiro zowotcha, fungo loyaka moto, kapena ngati mlanduwo ukutentha kwambiri. Mutha kugwiritsanso ntchito ma multimeter kuti muwone zolozera zina zosawoneka.
Kodi chowotcha chozungulira chingafooke?
Inde, wophwanya dera amafooka nthawi iliyonse akayenda. Maulendowa nthawi zambiri amakhudza kayendedwe kake ndi mawaya ndipo pamapeto pake amachititsa kuti chipangizocho chisiye kugwira ntchito pambuyo pa maulendo 4 (anayi) mpaka asanu (5).
