"Faulty xaim - qhov ua rau hluav taws!" - Qhov no yog daim ntawv ceeb toom sau cia kom paub txog peb txij li thaum me nyuam yaus. Tab sis yuav ua li cas thiaj paub tseeb tias cov hluav taws xob hluav taws xob yog nyob rau hauv qhov xwm txheej zoo (lossis puas) lub xeev? Nws tsis tas yuav tau tos rau hluav taws, muaj ntau tus cwj pwm ntau.
Lub zog rhuav tshem, puas tsuaj rau lub hwj chim sib tw tuaj yeem tshwm sim vim tias lub sijhawm tsis zoo hauv lub sijhawm "twists", tsis muaj zog nrog cov xov hluav taws xob thaum lub sijhawm tsis muaj tseeb. Txoj kev nthuav dav dav dav ntawm lub xeev ntawm cov xaim hluav taws xob tsis yog ib txwm pom, tab sis rau ntau cov paib koj tuaj yeem twv tau tias nrog lub zog hluav taws xob tsis yog txhua yam.

Ib qho ntawm txoj kev sib yuav wiring yog nquag "knocking tawm" ntawm RCD. Cov cuab yeej yuav ua txhaum txhua qhov sib npaug tam sim no, yog li ntawd nws yog qhov ua tau tias cov khoom siv tiv thaiv - hluav taws xob, hluav taws xob applicatus txuas nrog lub network yog faulty. Muaj lwm yam, ntau qhia cov cim ntawm kev ua txhaum kev sib tw: txim, cua sov, yaj tam sim no-nqa seem. Tej zaum txawm meej meej hnov Guau - ceev faj kom tiv thaiv PE tiv thaiv.

Nrog rau tej teeb meem, ua ntej txhua yam, tua lub voltage hauv lub network. Txhua txoj haujlwm yog nqa tawm tsuas yog nyob ntawm ib xaim hluav taws kub xwb! Them lawv yuav tsum yog tus neeg hluav taws xob tsim nyog. Ua ntej, lub network yog kuaj xyuas cov chaw ntawm cov kev puas tsuaj (piv txwv li, xau dej). Tom qab ntawv xyuas cov hlau sib txuas hauv lub thawv hlws ris raws li lub dav hlau-txheej txheem ntawm cov tsev apartment lossis hauv tsev. Kuj ntsuas lub xeev cov khoom siv hluav taws xob, yog tias tsim nyog, zawm cov ntsia hlau terminals nyob rau hauv lub bockets thiab keyboards. Nco ntsoov tias cov ntsia hlau sib txuas ntawm lub network yuav tsum tsis tu ncua, tsawg kawg ib xyoos ib zaug, tshuaj xyuas thiab muab tso rau hauv kev txiav txim. Tom ntej no, tus kws tshaj lij tuaj yeem ntsuas cov kev qhia tshwj xeeb. Kev ncaj ncees ntawm txoj saw hlau yog soj ntsuam nrog tus multimeter megausmeter, cov rwb thaiv tsev tsis kam ntawm cov xov hluav taws xob ntsuas. Raws li cov cai ntawm cov khoom siv hluav taws xob (PEE), rau hluav taws xob hluav taws xob nce mus txog 1 kV, rwb thaiv tsev tsis kam yuav tsum yog tsawg kawg 0.5 mω.

Yuav ua li cas qhia kom meej qhov chaw ntawm cov teeb meem xaiv ntawm xaim? Nyob rau hauv domestic tej yam kev mob, tau kawg, nws yog qhov nyuaj ua. Lub malfunction qhia ib txoj haujlwm tsis txaus siab ntawm cov cuab yeej tiv thaiv, yog li nws yog qhov zoo dua los ua ib chav tsev lossis ib lub tsev thiab tos hluav taws xob. Tab sis nws yog ua tau los txo qhov kev pheej hmoo ntawm kev ua tsis tiav ntawm xaim. Ua ntej, cov cuab yeej yuav tsum tau xaiv tau raug. Cov cuab yeej ua txhaum tuaj yeem xa ntau yam teeb meem. Thib ob, nws tsim nyog hloov cov qub hlau hlau rau ntau niaj hnub thiab txhim khu kev qha. Thib peb, nws yog ib qho yuav tsum tau rau nruab cov khoom siv uas txiav txim siab ua kom haum, nrog rau hluav taws xob thiab hluav taws xob clips - kev ruaj ntseg tsis tshwm sim ntau.
