Ulivivinya Kanjani Isokhethi le-GFCI nge-Multimeter (Izinyathelo ezi-5)

Ingabe ucabanga ukuthi i-GFCI yakho ayihambi kahle? Ukuze uthole ukuthi yini ebangela ukuthi i-outlet ingasebenzi kahle, kungcono ukuhlola nge-multimeter.

Landela lezi zinyathelo ukuze uhlole i-GFCI nge-multimeter. 

Okokuqala, udinga ukuhlola i-GFCI yakho ukuze uthole noma imaphi amaphutha. Ukuze wenze lokhu, sebenzisa izinkinobho "TEST" kanye "SETHA KABUSHA". Okulandelayo, faka i-multimeter ku-grooves. Udinga ukuqinisekisa ukuthi kukhona amandla asele endaweni yokuphuma (ngenkathi icishiwe). Okulandelayo, kala i-voltage endaweni yokuphuma. Lesi sinyathelo sihloselwe ukunquma ukuthi i-GFCI idlulisela i-voltage efanele yini. Bese uhlola izintambo ze-outlet. Qala ngokuvala amandla usebenzisa iswishi eyinhloko. Khipha isokhethi bese uyikhipha odongeni. Bheka noma yiziphi izintambo ezipeshisiwe noma ukuxhumana okungafanele. Okokugcina, hlola ukuthi i-outlet isekelwe kahle yini. 

Kulo mhlahlandlela wezinyathelo ezi-5, sizokufundisa ukuthi ungayihlola kanjani i-GFCI yakho, okusiza ukuvimbela amaphutha kagesi nokushaqeka, kusetshenziswa i-multimeter kunoma imaphi amaphutha aphansi.

izidingo 

1. Multimeter - I-multimeter iyithuluzi elihle lokulinganisa amapharamitha kagesi afana ne-voltage, ukumelana, kanye namanje. Ungakhetha phakathi kwe-analog ne-digital multimeter. Uma ukubhajethi, i-analog multimeter izokwenza. Nokho, uma ufuna idivayisi ethuthuke kakhulu, i-multimeter yedijithali ingaba ukubheja kwakho okuhle kakhulu. Ngaphezu kokumelana okuphezulu, baphinde banikeze izibonisi ezinembile zedijithali. Ama-DMM afaneleka kakhulu ukulinganisa amandla kagesi, ikakhulukazi lapho kuhlolwa indawo ye-GFCI. (1)

2. Izinto zokuzivikela - Ezandleni, sebenzisa amagilavu ​​avikelayo akwazi ukuhlukanisa ugesi ngokuphelele nangokuthembekile. Kungaba usizo uma futhi unocansi oluvikelayo oluvimbela ugesi ukuthi ungadluli usuka phansi nasemzimbeni wakho uma kwenzeka kuba nephutha phansi. Ngaphambi nangemuva kokuxazulula inkinga isihlukanisi sesekhethi se-GFCI, uzodinga ukunquma ukugeleza kwamanje kokuphakelwa kwamandla. Phatha isithwebuli se-voltage nawe esikhundleni sokusebenzisa ngephutha isinqamuli se-GFCI esibukhoma. Izobonisa izinga lamanje likagesi. (2)

5-Izinyathelo Ground Ground Testing Umhlahlandlela

Ukuhlola okukhiphayo kwe-GFCI kuyinqubo elula uma usebenzisa i-multimeter. Nazi izinyathelo ezinemininingwane zokuthola ukuthi ukushintshwa kwe-GFCI kunephutha yini.

1. Hlola i-GFCI (I-Ground Fault Circuit Breaker) 

Udinga ukuhlola i-GFCI ukuze uthole amaphutha. Ukuze wenze lokhu, sebenzisa izinkinobho "TEST" kanye "SETHA KABUSHA". Cindezela mathupha inkinobho ethi "TEST" uze uzwe ukuchofoza isokhethi, okusho ukuthi amandla avaliwe. Bese ucindezela inkinobho ethi "SETHA KABUSHA". Kwesinye isikhathi inkinga ingase ibe sekushintsheni. Bona ukuthi iyachofoza futhi ihlala endaweni.

2. Ukufaka i-multimeter ezikhaleni 

Udinga ukuqinisekisa ukuthi kukhona amandla asele endaweni yokuphuma (ngenkathi icishiwe). Beka ama-probe epulaki ye-multimeter ezindaweni eziqondile, uqale ngocingo olumnyama bese ulandela ucingo olubomvu. Ukufundwa kukaziro kukhombisa ukuthi indawo yokuphuma ivikelekile futhi iqinisekisa ukuthi isasebenza.

Ukuze uvule amandla, cindezela inkinobho ethi RESET futhi uqhubeke ukala i-voltage esakhiweni se-GFCI.

3. Ukulinganisa i-voltage kusokhethi 

Lesi sinyathelo sihloselwe ukunquma ukuthi i-GFCI idlulisela i-voltage efanele yini. Setha i-analog noma i-multimeter yedijithali kunani lokumelana bese ukhetha isikali esiphezulu. Ama-multimeters anesethingi yokumelana enkulu kunendawo eyodwa kufanele asethelwe ku-1x.

Usulungele ukuhlolwa kwephutha eliphansi ngemuva kokusetha i-multimeter. Xhuma i-probe eyodwa kutheminali ukuze enye ithinte ikesi ledivayisi noma ubakaki wokukhweza. Bese uhambisa uphenyo lokuqala oluthinta itheminali uye kwenye itheminali. Iphutha eliphansi likhona uma i-multimeter yakho ifunda noma yini enye ngaphandle kwe-infinity nganoma yisiphi isikhathi esivivinyweni. Ukuntuleka kokufunda kukhombisa izinkinga. Ungase uthande ukucabangela ukuhlola izintambo ze-outlet.

4. Ukuhlola izintambo ze-outlet 

Qala ngokuvala amandla usebenzisa iswishi eyinhloko. Khipha isokhethi bese uyikhipha odongeni. Bheka noma yiziphi izintambo ezipeshisiwe noma ukuxhumana okungafanele. Izintambo zakho aziyona inkinga inqobo nje uma intambo emnyama ixhunywe kupheya "yomugqa" kanye nentambo emhlophe epheya "yomthwalo" wezintambo. Bona ukuthi imibala ifanelana ngokufanele - emnyama kufanele ihambisane nomnyama nomhlophe nomhlophe.

Hlola ukuthi amantongomane ocingo aboshwe ngokuvikelekile yini ezixhunyweni, uma konke kuhamba ngendlela. Buyela kuphaneli kagesi eyinhloko, vula amandla bese uhlola i-voltage futhi nge-multimeter. Qaphela ngenkathi wenza lokhu, ngoba ubuyisele amandla aphilayo kumasekethe.

5. Ingabe isokhethi isekelwe kahle?

Lesi sinyathelo siyefana nesinyathelo sesi-3 (isilinganiso samandla kagesi). Umehluko kuphela ukuthi ukuhola okumnyama kwe-multimeter kungena endaweni emise u-U (ephansi) yomhumushi wephutha lomhlaba. Lindela ukufundwa kwamandla kagesi afana nalawa okhethe ngaphambilini uma i-outlet isekelwe kahle. Ngakolunye uhlangothi, uma ufunda i-voltage ehlukile, ubhekene ne-outlet esekelwe ngokungafanele noma izintambo ezingalungile.

Ukuxazulula inkinga ukushintsha kwe-GFCI kufanele kube yinto yanyanga zonke. Lokhu kungenye yezinto okufanele uzenze ukuze uphephe. Uma isokhethi iyeka ukusebenza njengangaphambili, yishintshe. Ngeke wazi ukuthi uyokhothama nini.

Indlela yokulungisa iphutha lomhlabathi

Indlela efaneleke kakhulu yokuqeda iphutha eliphansi iwukuba esikhundleni socingo olungalungile. Uma ubhekene nocingo olulodwa noma eziningi ezimbi noma ezindala, ungazisusa futhi ufake ezintsha. Ngezinye izikhathi iphutha eliphansi lingaba engxenyeni ethile. Esimweni esinjalo, kungcono ukufaka yonke le ngxenye esikhundleni. Ukulungisa lokhu akuphephile futhi akufanele kube nzima. Kuyingozi ukusebenzisa ingxenye enephutha lomhlabathi. Ukuze uxazulule inkinga yesisekelo, thenga ingxenye entsha bese uyishintsha ngokuphelele. Lokhu kuphephile kunokulungisa ingxenye. Futhi, ingxenye entsha ikunikeza ukuthula kwengqondo ngoba isekethe yakho ye-GFCI izoba sesimweni esihle ngemva kokushintsha ingxenye yephutha eliphansi.

Ukuqeda iphutha eliphansi akunzima. Mhlawumbe inkinga ilele ekuzitholeni, ikakhulukazi uma usebenza nesekethe enkulu noma uhlelo lwe-GFCI. Uma kunjalo, hlukanisa uhlelo lube izingxenye ezincane, ezilawulekayo. Futhi, lapha uzothola isivivinyo sokubekezela kwakho. Ukuze ugweme ukudumala futhi uqinisekise ukuhlola ngempumelelo isokhethi ye-GFCI, thatha isikhathi sakho ukuqeda. Ungajahi.

Ukufingqa

Ingabe uthole lesi sihloko sinolwazi? Manje njengoba usufundile ukuhlola isokhethi le-GFCI nge-multimeter, izame. Njengoba kushiwo ngaphambili, le nqubo kufanele yenziwe njalo ngenyanga njengoba amaphutha aphansi engase abe yingozi. Ngaphezu kokushaqeka kukagesi okuyingozi, amaphutha aphansi nawo angabangela ukuthi idivayisi ingasebenzi kahle.
