Ukusombulula ngokufanelekileyo isekethe yombane, kufuneka wazi ukuba icandelo ngalinye lombane kwiyunithi kufuneka lisebenze kwaye likwazi ukuvavanya ukusebenza kwecandelo ngalinye. Iirekhodi zombane, ushicilelo, ucwangciso noncwadi lwabenzi—kunye nolwazi namava akho—ziya kukunceda ubone indlela ekulindeleke ukuba icandelo ngalinye lisebenze ngayo. Emva kokumisela iimpawu zokusebenza ezilindelekileyo, sebenzisa iimitha zombane ukufumana iimpawu zokusebenza zangoku zesekethe.

Ezinye iimeko zikwafuna ukuvavanyelwa amandla, into yamandla, ukuphindaphinda, ukujikeleza kwesigaba, inductance, amandla, kunye ne-impedance. Ngaphambi kokuba uqalise naluphi na uvavanyo, phendula le mibuzo mihlanu ilandelayo:

● Ngaba isekethi ivuliwe okanye icinyiwe?

● Injani imeko yeefusi okanye iziqhekeza?

● Ziyintoni iziphumo zokuhlolwa okubonwayo?

● Ngaba kukho ukupheliswa kakubi?

● Ngaba imitha iyasebenza?

Iimitha kunye nezixhobo zokuvavanya, kunye nezixhobo zokuprinta, ezifana nezigodo zokusebenza kunye ne-schematics, zonke ziya kukunceda ukuxilonga kunye nokusombulula iingxaki zombane. Izixhobo ezisisiseko zokuxilonga kunye nezixhobo zovavanyo yi-voltmeter, i-ammeter, kunye ne-ohmmeter. Imisebenzi esisiseko yale mitha idibaniswe kwi-multimeter.

IiVoltmeters

Sebenzisa i-voltmeter ukuvavanya amandla ombane kwi-motor. Ngokusebenza kwejeneretha, i-switch ivaliwe, kunye ne-voltmeter probes efakwe kwi-conductor yangoku kunye ne-neutral conductor connections ye-motor, i-voltmeter iya kubonisa amandla ombane kwi-motor. Uvavanyo lwe-voltmeter lubonisa kuphela ubukho bombane. Ayiyi kubonisa ukuba i-motor iyajika okanye i-current yangoku ihamba.

Ammeters

I-clamp-on ammeter isetyenziselwa ukuvavanya i-amperage kwisekethe yemoto. Ngokusebenza kwejeneretha, ukutshintshela kuvaliwe, kunye nemihlathi ye-ammeter igxininiswe malunga nokuba yiyiphi i-lead, i-ammeter iya kubonisa i-amperage draw, okanye yangoku, esetyenziswa yisekethe. Ukufumana ufundo oluchanekileyo xa usebenzisa i-ammeter ebambezelayo, qinisa imihlathi yemitha kucingo nje olunye, okanye ilothe, ngexesha, kwaye uqinisekise ukuba imihlathi ivaleke ngokupheleleyo.

Oohmeters

I-ohmmeter ivavanya ukuxhathisa kwenjini. Phambi kokuba uqalise uvavanyo lwe-ohmmeter, vula iswitshi elawula imotor, ncamathela isixhobo esifanelekileyo sokutshixa/ukukhupha, kwaye ukwahlula injini kwisekethe. Uvavanyo lwe-ohmmeter lunokuchonga isiphaluka esifutshane okanye esivulekileyo.

Quick-Test Izixhobo

Izixhobo zombane ezininzi ezikhethekileyo, ezisebenzayo, nezingabizi kakhulu ziyafumaneka ukuze zisetyenziswe ekuxazululeni iingxaki kwiisekethe zombane. Ngaphambi kokusebenzisa naziphi na izixhobo zovavanyo zombane, qiniseka ukuba ziyayithobela imigaqo ye-OSHA yangoku.

Iimpawu zamandla ombane zizixhobo zepokotho ezifana nepeni ezisetyenziselwa ukujonga ubukho bamandla ombane we-AC ngaphezulu kwe-50 volts. Iimpawu zombane ziluncedo xa ujonga ikhefu kwiingcingo ze-AC. Xa incam yeplastiki yesalathisi isetyenziswe kuyo nayiphi na indawo yokudibanisa okanye ecaleni kwentambo ene-AC voltage, i-tip iya kukhanya okanye isixhobo siya kukhupha isandi esikhalayo. Iimpawu zombane azilinganisi umbane we-AC ngokuthe ngqo; zibonisa amandla ombane.

Abahlalutyi beesekethe baplagi kwizixhobo eziqhelekileyo kwaye banokusebenza njengesiseko sovavanyo lombane, ebonisa amandla ombane akhoyo. Ezi zixhobo zeplagi zisetyenziswa ngokuqhelekileyo ukuvavanya ukungabikho komhlaba, i-polarity eguqulwayo okanye ukungathathi hlangothi, kunye nokuhla kwamandla ombane. Zikwasetyenziselwa ukujonga i-GFCI. Iinguqulelo ezintsonkothileyo zesi sixhobo zinokujonga ukunyuka kwamandla ombane, izizathu ezingeyonyani, umthamo wangoku, ukungasebenzi, kunye neengozi zokhuseleko.

Izikena ze-infrared zisetyenziswa rhoqo ukujonga iingxaki ezinokubakho zombane. Njengoko i-amperage idlula kwisixhobo sombane, ubushushu buveliswa ngokulingana nokumelana okwenziwayo. Iskena se-infrared siqaqambisa umahluko wobushushu phakathi kwezinto kwaye sinokucwangciswa ukubonisa awona maqondo obushushu. Ukuba nayiphi na isekethi okanye into ishushu ngaphezu kwezinto ezisingqongileyo ngokukhawuleza, eso sixhobo okanye uqhagamshelwano luya kubonakala njengendawo eshushu kwiskena. Naziphi na iindawo ezishushu ngabaviwa bohlalutyo olongezelelweyo okanye ukulungisa iingxaki. Iingxaki ze-Hot-spot zivame ukusonjululwa ngokuhlengahlengisa i-torque kunxibelelwano lombane olukrokrelwayo ukuya kwinqanaba elifanelekileyo okanye ngokucoca kunye nokuqinisa zonke izihlanganisi. Ezi nkqubo zinokulungisa kwakhona ukungalingani kwesigaba.

IiTracer zeSekethe

I-circuit tracer sisixhobo esinokuthi, xa sifakwe kuyo nayiphi na indawo efikelelekayo kwisiphaluka, inokulandelela i-wiring yesiphaluka kwisakhiwo-yonke indlela yokungena kwinkonzo, ukuba kuyimfuneko. Iitrayisi zesekethe zineenxalenye ezimbini:

●Ijenereyitha yoMqondiso:Incamathela kwiingcingo zesekethe kwaye idale isignali yohlobo lwamaza erediyo kuyo yonke isekethe.

●Umamkeli womqondiso:Fumana iingcingo zesekethe ngokufumana isignali yerediyo ngocingo.

IiRekhodi zoMbane, iiShicilelo, iiSchematics, kunye noNcwadi lwabavelisi

Njengoko ziluncedo njengoko ezinye zezi zixhobo zinjalo, amaxwebhu ahlala ngokulinganayo okanye abaluleke ngakumbi. Iirekhodi zokuhlola kunye neelog zokusebenza ziquka ulwazi olufana ne-amperage draw kunye namaqondo okushisa okusebenza kunye noxinzelelo lwamacandelo. Utshintsho kuyo nayiphi na kwezi parameters lunokubonisa iingxaki ezinokuba khona kumbane. Xa kukho ingxaki ebonakalayo, iirekhodi zokuhlola kunye neelogi zokusebenza zinokukunceda uqhathanise ukusebenza kwangoku kwezixhobo kwiimeko eziqhelekileyo zokusebenza. Olu thelekiso lunokukunceda ngakumbi ukuba uchonge iindawo ezinengxaki ethile.

Ngokomzekelo, ukunyuka kwe-amperage draw ye-motor ukuqhuba ipompo kubonisa ingxaki enokubakho. Ukuqaphela utshintsho kwi-draw amperage draw, unokwenza iimvavanyo ezongezelelweyo, ezifana nokujonga ukushisa okusebenzayo kweebheringi. Ngaphaya koko, ukuba iqondo lobushushu leebheringi lingaphezulu kobushushu bokusebenza, uhlobo oluthile lolungiso lunokuba yimfuneko kwaye kufuneka lucwangciswe. Ngaphandle kokubhekisela kwiilogi zokusebenza, awukwazi ukuqaphela imiba enjalo. Olu hlobo lolongamelo lunokukhokelela ekonakaleni kwesixhobo.

Ushicilelo, imizobo, kunye neschematics ziluncedo ekumiseleni indawo yesixhobo, ukuchonga amacandelo aso, kunye nokucacisa ulandelelwano olufanelekileyo lokusebenza. Uya kusebenzisa iintlobo ezintathu ezisisiseko zokuprinta kunye nemizobo ekuxazululeni iingxaki zombane kunye nokulungiswa.

●Iiplani "Njengokwakhiwa" kunye nemizobo yombanebonisa indawo kunye nobukhulu bezixhobo zokulawula unikezelo lwamandla, ezifana nokutshintsha kunye nee-circuit breakers, kunye nendawo yocingo kunye neentambo. Izinto ezininzi zimelwe ziisimboli eziqhelekileyo. Amacandelo angaqhelekanga okanye angaqhelekanga abonwa ngokubanzi kumzobo okanye kwisitshixo somzobo esahlukileyo sombane.

●Imizobo yokufakelayimifanekiso yemifanekiso yezixhobo zombane eziluncedo ekufumaneni iindawo zoqhagamshelo, iingcingo, kunye nezinto ezithile. Iisimboli zombane eziqhelekileyo azifuneki, kodwa ezinye zingasetyenziselwa ukwenza lula.

●Izicwangciso, okanye imizobo yeleli, yimizobo eneenkcukacha ebonisa indlela isixhobo esisebenza ngayo ngombane. Ezi zithembele kakhulu kwiisimboli eziqhelekileyo kwaye zinengcaciso encinci ebhaliweyo.

Uncwadi lwabavelisi lunokubandakanya ukufakela kunye nemizobo yeskim, kunye nemiyalelo kunye neetheyibhile ezichaza umsebenzi othile okanye iiparamitha zokusebenza. Lonke olu lwazi kufuneka lufumaneke lula kuwe.
