Txhua yam khoom siv hluav taws xob tuaj yeem tawg. Yog tias nws nyuam qhuav nres ua haujlwm - nws yog ib nrab ntawm qhov teeb meem. Qhov phem tshaj, yog tias qhov ua tsis tau zoo ua rau muaj kev nkag mus ntawm cov hluav taws xob hluav taws xob ntawm cov khoom ntawm nws cov qauv tsim, uas tus neeg siv xav tias muaj kev nyab xeeb. Tsis txhob kov tej khoom ntawd, ib tug neeg yuav raug hluav taws xob, tej zaum yuav raug mob los yog phem dua…

Yuav tiv thaiv av yog dab tsi

Nrog rau kev so sab hauv hauv tus neeg xyuas pib, nws tuaj yeem ua rau nws kov lub cev ntawm lub vaj huam sib luag hluav taws xob lossis lwm yam khoom siv, thiab qhov no tom kawg yuav muaj kev phom sij hauv ntiaj teb, tsis pom, thiab yog li ntawd ob npaug txaus ntshai. Txhawm rau zam qhov xwm txheej zoo li no, siv cov khoom siv hauv av. Lawv mounted yooj yim heev, tab sis lawv yeej yuav tsum tau raws li ib tug xov tooj ntawm cov kev cai.

Cov khoom siv sab nraum zoov, nrog rau txhua yam khoom siv nyob rau hauv qhov chaw ntub dej, yuav tsum tau muab tso rau hauv av thiab hauv av yog tias cov khoom siv hluav taws xob ntau tshaj 42 V AC, lossis 110 V DC. Tib yam siv rau tag nrho cov hlau uas tsis yog tam sim no-nqa qhov chaw ntawm cov cuab yeej hluav taws xob, lub thawv, cov ntaub thaiv npog thiabcov qauv nyob rau hauv uas lub cable yog routed.

Yuav ua li cas hauv av muaj

Cov khoom siv hauv av muaj ob qhov tseem ceeb.

Thawj ntawm cov no yog hu ua grounding conductor, thiab feem ntau nws yog lub tsev tsim ntuj tsim, xws li fittings, faus pipelines thiab lwm qhov chaw uas muab kev ntseeg siab thiab rov sib cuag nrog hauv av. Yog tias, vim qee qhov xwm txheej, cov qauv zoo li no tsis tuaj lossis tsis muaj, cov khoom siv hauv av yog siv. Lawv yog cov ces kaum steel khawb rau hauv av mus rau qhov tob ntawm yam tsawg 60 cm nrog ib sab loj ntawm 5 cm thiab ib tug tuab ntawm tsawg kawg yog 4 mm. Qhov ntev ntawm txhua yam ntawm cov ntsiab lus no yuav tsum yog tsawg kawg 3 meters, lawv nkag mus tob rau hauv av, ces steel strips yog welded rau lawv, uas cov conductors yog fastened, uas yog, qhov thib ob ntawm cov qauv uas ua kom muaj kev ruaj ntseg hluav taws xob.

Ntiaj Teb Yuav Tsum

Qhov kev tiv thaiv ntawm cov cuab yeej hauv av yuav tsum tsawg, yog li cov kev xav tau rau kev sib cuag kev ntseeg siab heev. Nws lub hom phiaj tseem ceeb yog los tsim cov xwm txheej rau kev tua hluav taws xob thaum muaj kev sib cuag ntawm cov khoom nqa tam sim no nrog cov ntsiab lus uas nyob rau hauv ib txwm ua haujlwm yuav tsum tsis txhob muaj zog. Tib neeg lub neej feem ntau nyob ntawm seb qhov kev kub ntxhov tshwm sim sai npaum li cas.

Kev saib xyuas hauv av

txhawm rau tswj cov qib kev nyab xeeb ntawm hluav taws xob,Kev ntsuas lub sijhawm ntawm cov khoom siv hauv av. Lub ntsiab lus ntawm lub cev ntawm cov txheej txheem no yog txiav txim siab qhov kev tiv thaiv tiag tiag los ntawm qhov tam sim no yuav ntws thaum muaj xwm txheej ceev. Rau qhov no, cov khoom siv tshwj xeeb yog siv, nruab nrog kev sojntsuam tswj thiab sawv cev rau qhov tseeb ohmmeters (piv txwv li, MRU-101).

Ntawm cov chaw lag luam, cov neeg ua haujlwm tshwj xeeb yog lub luag haujlwm rau kev nyab xeeb hluav taws xob, feem ntau yog tus thawj tswj hwm lub zog, lub taub hau ntawm kev pabcuam tiv thaiv kev ua haujlwm thiab, tau kawg, kev tswj hwm. Hauv lawv lub tsev, lub teb chaws lossis lub tsev ntiag tug, cov khoom siv hauv av yog tswj hwm los ntawm cov tswv ntawm cov cuab yeej.

Nyob zoo thiab ceev faj!
