3. Tus neeg xyuas pib xaim txoj kab uas hla - Cov neeg siv khoom yuav tsum tau saib xyuas seb tus neeg xyuas pib xaim txoj kab uas hla yog raws li qhov sib txawv ntawm cov lus qhia ntawm daim ntawv pov thawj thaum yuav khoom. Yog hais tias tus neeg xyuas pib hla ntu me me dhau, nws yooj yim ua rau cov xaim cua sov thiab ua rau luv luv. Nws raug pom zoo tias cov xov hlau siv hauv tsev teeb pom kev zoo yuav tsum yog 1.5 mm2 thiab siab dua; Cov khoom siv hauv tsev nrog lub zog siab xws li cua txias thiab microwave ncu yuav tsum siv cov xov hlau ntawm 2.5 mm2 thiab siab dua.
4. Kev siv tus qauv - cov xaim yuav tsum yog tus qauv. Nws yog qhov zoo tshaj plaws los siv BV ib leeg-ntxhais xov hlau los hnav cov kav dej rau cov kab ruaj khov. Ceev faj kom tsis txhob ua kom cov xaim hluav taws xob puas thaum siv hluav taws xob, thiab tsis txhob ua kom cov xaim hluav taws xob puas thaum kho chav; tsis txhob txuas hauv nruab nrab ntawm txoj kev; Tsis txhob kov cov xov hlau thaum nkag mus rau hauv lub thawv hluav taws xob (lub thawv); Tsis tas li ntawd, cov khoom siv hauv tsev uas siv hluav taws xob ntau, xws li cov tshuab cua txias, yuav tsum tau siv los ntawm cov xaim cais; Nws yog qhov zoo tshaj kom khaws ib qho kev ncua deb ntawm cov xov hlau siv rau qhov tsis muaj zog tam sim no thiab muaj zog tam sim no.
Feem ntau cov faults nyob rau hauv cable kab muaj xws li mechanical puas, rwb thaiv tsev puas, rwb thaiv tsev damp, rwb thaiv tsev laus thiab deterioration, overvoltage, thiab cable overheating faults. Thaum qhov kev ua txhaum saum toj no tshwm sim hauv kab, lub hwj chim ntawm lub faulty cable yuav tsum raug txiav tawm, qhov txhaum yuav tsum tau pom, qhov txhaum yuav tsum tau kuaj xyuas thiab tshuaj xyuas, thiab tom qab ntawd kho thiab kuaj.
