Dab tsi ua rau partensatause qhia yog tias qhov hluav taws xob yog av lossis luv?
Nyob rau hauv qhov kev tshwm sim ntawm lub zog hluav taws xob, siv ntau sib xyaw nrog lub 10k iav kom kaw lub nra thiab ntsuas qhov Circuit Court. Thaum muaj peb ntu thiab plaub xaim, cov nqi tiv taus ntawm plaub kab yuav tsum tau muab tso rau ib leeg-theem yuav tsum tau ua kom pom zoo li tsis kawg. Thaum muaj tus nqi tiv, nws tuaj yeem txiav txim siab tias muaj ib txoj kab luv hauv kab. Txhawm rau txiav txim siab gelling, siv ntau txoj kev sib tw kov ib qho kawg ntawm ib qho kev sojntsuam nrog ib qho kev sojntsuam, thiab ntsuas rau cov kev tawm tsam nrog rau lwm qhov kev sojntsuam. Yog hais tias tus nqi tiv thaiv yog qhov tsis kawg, nws yog qhov qub. Txwv tsis pub, muaj qhov tshwm sim hauv av. Siv hom no los ntsuas txhua txoj xov hlau ib qho los ntawm ib qho los nrhiav qhov teeb meem. Tsis tas li, nco ntsoov tias yog tias nws yog tus hlau strip cable, tso lwm qhov kawg ntawm kev sojntsuam ntawm cov steel sawb rau kev ntsuas. Txhawm rau kom paub tseeb qhov tseeb, nws yog qhov zoo tshaj plaws los ua ntej kuaj seb puas muaj kev qhib Circuitalimeter, thiab tom qab ntawd siv ntau ntau los kuaj xyuas cov voj voog luv luv thiab ua yuam kev. Qhov tseeb, kom daws tau ob hom kev ua txhaum, cov cuab yeej xws li moeghmmeters thiab detectors yuav siv tau los saib xyuas sai dua thiab muaj tseeb dua.
Siv cov khoom siv teeb pom kev zoo li ib qho piv txwv: Kev siv hluav taws xob hauv tsev yog cov hlau nyob, ib qho nruab nrab hlau, thiab hauv av xaim. Yog hais tias cov hlau nyob thiab nruab nrab ntawm xaim yog luv luv raws li lub voj voog luv, cov Circuit Court breaker yuav mus ncig. Lub sijhawm no, txhua yam khoom siv hluav taws xob yuav tsum tau muab cov hluav taws xob hluav taws xob yuav tsum tau muab tua, thiab cov xaim hluav taws xob xaus (cov hlau nyob nruab nrab Siv ib tug sib ntau sib ntau los ntsuas cov nqi tiv thaiv ntawm ob kab hauv ib hom nruab nrab, uas yuav tsum muaj qhov tsis kawg. Yog hais tias tus nqi tiv taus yog xoom lossis tsuas yog ob peb ohms, nws txhais tau tias cov hlau nyob thiab nruab nrab ntawm cov xaim hluav taws xob yog luv.
Tig rau Circuit Court breaker, tsis txhob nruab ob xaus kab lus, tua ib qho khoom siv hluav taws xob, thiab siv cov khoom siv hluav taws xob rau cov neeg siv hluav taws xob xaus thiab cov kev sojntsuam rau tus neeg siv cov kab kawg. Yog tias muaj qhov hluav taws xob ntawm txog 200 volts, nws ua pov thawj tias lub Circuit Court yog qhov av.
Hauv Tuam Tshoj qhov hluav taws xob tsawg-voltage, nws tau hais tias lub qhov ncauj lus nruab nrab yuav tsum tau cog, thiab cov xaim nruab nrab tsis tuaj yeem siv ua av xaim. Cov hlau muaj siab tiv thaiv av hlau yuav tsum muab ntsia nyias. Tom qab nkag mus rau tus neeg siv lub thawv hluav taws xob, cov xov hlau nyob thiab nruab nrab yuav tsum yog insulated los ntawm hauv av kom ua haujlwm zoo. Thaum cov tsis kam ntawm cov hlau nyob lossis nruab nrab mus rau hauv av xaim yog tsawg dua {}}.
Tom qab taug kev tshwm sim, muaj ntau txoj kev siv tau los tshawb xyuas seb qhov Circuitats thiab thauj khoom qab ntawm Circuit Court breaker yog cov hauv paus. Cov qauv yog raws li hauv qab no:
Disconnect lub hwj chim tseem ceeb hloov thiab txiav cov hlau nruab nrab ntawm lub zog hluav taws xob. (Qee qhov kev sib txuas sib txuas nrog cov xaim hluav taws xob muaj qhov nruab nrab uas tseem tsis tu ncua nyob rau hauv txoj haujlwm qhib thiab yuav tsum tau muab tshem tawm cov xaim hluav taws xob ntau tshaj li 1m Yog tias tus nqi tiv taus tsawg dua 0. 5m ohms, nws raug txiav txim tsis muaj qhov tsis tsim nyog.
Yog tias qhov tsis kam ntawm cov kav hlau nyob thiab nruab nrab rau hauv av xaim yog tsim nyog, nws qhia tias nws tsis yog qhov tsis raug txhaum. Tom qab ntawd tsuas yog pulillimeter tuaj yeem siv los ntsuas cov nqi tiv taus ntawm cov kav hlau nyob thiab nruab nrab (txhua yam hluav taws xob yuav tsum tau muab cov hluav taws xob tsis zoo Yog tias tsis muaj teeb meem nrog Circuit Court, nws yuav muaj teeb meem ntau dua, thiab teeb meem nyob nrog cov khoom siv hluav taws xob. Xyuas lawv ib los ntawm ib!
