Yuav ua li cas nrhiav tau ib tug grounding los yog luv luv Circuit Court
Tab sis kuv tseem yuav teb cov lus nug txog yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nws nws yuav tsum tau txiav txim siab txog kev tiv thaiv kab mob sib kis los ntawm kev sib kis ntawm riam riam tsis muaj kev cuam tshuam los ntawm cov khoom siv hluav taws xob. (Qhov tseeb, yog tias muaj qhov luv luv hauv Circuit Court ntawm riam hloov kev faib tawm, qhov tshwm sim yog kub hnyiab tawm ntawm cov xov hlau lossis ua rau cov riam hloov ua kom puas tsuaj. Txawm li cas los xij, kuv tseem yuav teb cov lus nug raws li txoj cai tshawb nrhiav.).
1) Tshem tawm lub hwj chim hloov thaum pib ntawm txoj kab xa tawm, tshem tawm tag nrho cov hloov pauv ntawm txoj kab, suav nrog cov ntsaws ntsaws ntsaws ntsaws ntsaws, thiab siv lub tshuab hluav taws xob los ntsuas qhov tsis kam ntawm ob txoj kab tawm ntawm lub hwj chim. hloov hauv 100 qib. Yog tias qhov kev tiv thaiv ntawm multimeter me me heev (piv txwv li lub pointer viav vias mus rau sab xis yuav luag mus rau qhov kawg), nws ua pov thawj tias muaj qhov luv luv ntawm cov kab theem thiab cov kab nruab nrab. Txwv tsis pub, tsis muaj luv luv Circuit Court. Tib txoj kev tshawb nrhiav yog siv los ntsuas seb puas muaj qhov luv luv ntawm cov kab hauv theem thiab cov kab tiv thaiv hauv av (nruab nrab), thiab nruab nrab ntawm cov kab nruab nrab thiab cov kab tiv thaiv av (tsis nruab nrab) kab.
2) Yog tias tsis muaj qhov luv luv ntawm theem xaim thiab cov xaim nruab nrab, theem xaim thiab kev tiv thaiv hauv av (nruab nrab) xaim, thiab cov xaim nruab nrab thiab kev tiv thaiv hauv av (tsis nruab nrab) xaim, ces nws tuaj yeem txheeb xyuas seb puas muaj. yog qhov tshwm sim hauv av ntawm theem xaim thiab cov xaim nruab nrab.
Yog tias koj muaj lub clamp meter ntawm tes, nws yog qhov zoo tshaj plaws los siv lub clamp meter los kuaj xyuas cov av tam sim no. Txoj kev tshawb nrhiav yog: thawj zaug tshem tawm lub hwj chim hloov, tshem tawm cov xaim nruab nrab ntawm lub hwj chim hloov hluav taws xob tawm lub davhlau ya nyob twg (thiab ua ib qho cim), tom qab ntawd kaw lub hwj huam hloov, thiab siv lub ntsuas hluav taws xob los ntsuas seb puas muaj qhov hluav taws xob hauv av. theem hlau (lub clamp meter yog thawj zaug teem rau 100A yog tias tsis muaj tam sim no ntsuas tau, thiab maj mam teem rau theem tam sim no me). Yog hais tias lub grounding tam sim no tseem ntsuas tsis tau; Koj tuaj yeem tshem tawm qhov grounding ntawm theem kab. Tom qab kuaj xyuas cov kab hluav taws xob, txiav tawm lub hwj chim hloov thiab tshem tawm cov theem kab, txuas cov kab nruab nrab mus rau theem kab hluav taws xob tiv tauj ntawm lub hwj chim hloov, kaw lub hwj chim hloov, thiab siv lub clamp meter saum toj no los ntsuas cov theem kab los xyuas qhov nruab nrab kab.
Yog tias koj tsis muaj lub ntsej muag zoo li lub moos ntawm tes; Koj tuaj yeem nrhiav tau lub teeb lub taub hau dai thiab lub teeb 25 watt incandescent, nruab lub taub hau teeb, thiab txuas ob lub xov hlau 15 centimeter rau thaub qab. Txoj kev kuaj xyuas yog:; Disconnect lub hwj chim hloov, tshem tawm cov theem xaim thiab nruab nrab xaim, ua ntej txuas lub teeb lub taub hau thiab qhov muag teev nyob rau hauv series ntawm theem xaim thiab theem xaim hluav taws xob tiv tauj ntawm lub hwj chim hloov, ntsuas kev nyab xeeb, thiab tom qab ntawd kaw lub hwj chim hloov. Yog hais tias lub teeb ci nyob rau lub sijhawm no, nws ua pov thawj tias theem xaim yog grounded. Qhov siab dua qhov ci ntsa iab ntawm lub teeb, qhov ntau dua qhov tam sim no hauv av, thiab rov ua dua. Yog tias lub teeb tsis teeb, lub grounding ntawm theem xaim tuaj yeem raug txiav tawm. Tom qab kuaj xyuas cov kab hluav taws xob, tshem tawm cov kab hluav taws xob, tshem tawm cov kab hluav taws xob, txuas cov khoom qub hauv cov kab nruab nrab ntawm cov kab nruab nrab thiab cov theem kab txuas ntawm lub qhov hluav taws xob hloov hluav taws xob, thiab tseem yuav ntsuas kev nyab xeeb. Kaw lub hwj chim hloov mus xyuas cov kab nruab nrab, thiab cov txiaj ntsig kev xeem yog tib yam li cov kab saum toj no.
