Kev ntsuas kev ua tau zoo ntawm Prepaid Hluav Taws Xob Meter Ua ntej xa khoom
Ua ntej lub ntsuas hluav taws xob prepaid tawm ntawm lub Hoobkas, peb yuav ua ntau yam kev sim ua haujlwm. Ntawm lawv, qhov ntsuas hluav taws xob tiv taus yog qhov tseem ceeb. Niaj hnub no, cia peb kawm txog txoj kev tiv thaiv qhov ntsuas hluav taws xob ntawm prepaid hluav taws xob ntsuas:
Ua ntej lub ntsuas hluav taws xob prepaid tawm ntawm lub Hoobkas, peb yuav ua ntau yam kev sim ua haujlwm. Ntawm lawv, qhov ntsuas hluav taws xob tiv taus yog qhov tseem ceeb. Niaj hnub no, cia peb kawm txog txoj kev tiv thaiv qhov ntsuas hluav taws xob ntawm prepaid hluav taws xob ntsuas:
1. Ib puag ncig tej yam kev mob: nyob rau hauv tej yam kev mob ntawm chav tsev kub thiab txheeb ze humidity ntawm tsis ntau tshaj 80 feem pua
2. Nyob rau hauv qhov kev sim, lub auxiliary Circuit Court uas nws siv voltage tsis ntau tshaj 40V yog grounded.
3. Ntxiv ib kawg ntawm 2KV sim voltage rau tag nrho cov txuas txuas voltage terminals, tam sim no terminals thiab tag nrho cov pab terminals nrog ib tug siv voltage ntau tshaj 40V. Lwm qhov kawg yog ntxiv rau cov hlau uas nkag tau los ntawm sab nraud ntawm lub ntsuas hluav taws xob hluav taws xob thiab lub pob hluav taws xob hauv av ntawm lub casing (yog tias lub zog hluav taws xob ntsuas hluav taws xob yog insulated, nws yog ntxiv rau cov phaj hluav taws xob uas muab tso rau hauv lub casing) .
4. Qhov kev sim ntsuas hluav taws xob yuav tsum tau nce ntawm xoom mus rau tus nqi teev nyob rau hauv qhov sib npaug hauv (5-10) s, khaws cia rau 1min, thiab tom qab ntawd poob rau xoom ntawm tib qhov ceev.
5. Qhov tshwm sim ntawm kev sim yog tias cov rwb thaiv tsev yuav tsum tsis txhob tawg, thiab lub ntsuas hluav taws xob yuav tsum ua haujlwm ib txwm ua tom qab kev sim.
6. Lub ntsuas hluav taws xob hluav taws xob uas tau dhau qhov ntsuas qhov ntsuas hluav taws xob raug xa mus rau lub tsev kawm ntawv theem pib.
7. Lub ntsuas hluav taws xob tsis tsim nyog yuav tsum qhia qhov tshwm sim tsis raug, sau rau hauv "Tshem tawm cov khoom tsis tsim nyog", muab tso rau hauv lub thawv uas yuav tsum tau ua thiab hloov mus rau qhov chaw ua haujlwm rov ua haujlwm.
