Cov ntsiab lus ntawm kev ua haujlwm thiab cov txheej txheem rau insulating multimeter
Txheej txheem cej luam: Lub rwb thaiv tsev multimeter yog siv los ntawm cov kws tshaj lij los ntsuas qhov kev tiv thaiv hluav taws xob ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab cov khoom siv kom paub tseeb tias cov khoom siv hluav taws xob zoo, xyuas kom meej tias cov cuab yeej ua tau raws li cov cai thiab cov qauv, txiav txim siab cov kev hloov ntawm cov cuab yeej ua tau zoo dhau sijhawm, thiab txiav txim siab. qhov ua rau poob. Ib qho cuab yeej ua haujlwm.
1. Qhov tseem ceeb ntawm rwb thaiv tsev ntsuas ntsuas
Cov kws kho mob siv cov kev ntsuas hluav taws xob tiv thaiv kom txo tau cov khoom siv tsis ua hauj lwm los yog tsis ua hauj lwm thiab ua kom muaj txiaj ntsig zoo tshaj plaws. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tiv thaiv qhov tshwm sim ntawm cov xwm txheej txaus ntshai xws li hluav taws xob poob siab thiab hluav taws, thiab ua kom muaj kev nyab xeeb ntawm tus kheej ntawm cov neeg ua haujlwm.
2. Rwb thaiv tsev tiv thaiv txheej txheem ntsuas
1. Ua ntej siv lub ntsuas ntsuas hluav taws xob rau kev ntsuas, cov kws tshaj lij yuav tsum ua ntej ua qhov ntsuas qhov ntsuas hluav taws xob, tam sim no thiab tsis kam.
2. Tom qab cov khoom siv de-energized, siv FLUCK rwb thaiv tsev multimeter los txiav txim siab qhov ncaj ncees ntawm cov windings lossis cables hauv motors, transformers, thiab switchgear. Kev ntsuas kev tiv thaiv hluav taws xob thiab kev ntsuas tam sim no yog ua los ntawm cov ntaub ntawv insulating los tsim cov nqi rwb thaiv tsev, saib daim duab 2.
3. Kev ua haujlwm nyab xeeb
(1) Ua ntej qhov kev xeem
1. Ua haujlwm ntawm de-energized circuits qhov twg ua tau, ntiav cov txheej txheem kaw kom raug / tagout
2. Yog tias qhov ntsuas hluav taws xob nyob hauv kev sim, siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab cov cuab yeej kev nyab xeeb.
3. Tshem tawm tag nrho cov hniav nyiaj hniav kub, thiab sawv ntawm cov roj hmab rwb thaiv tsev.
(2) Thaum kuaj
1. Tsis txhob txuas lub ntsuas hluav taws xob hluav taws xob rau cov neeg siv hluav taws xob nyob lossis cov khoom siv nyob, thiab ua raws li cov chaw tsim khoom cov lus pom zoo.
2. Tua lub cuab yeej nyob rau hauv kev sim los ntawm ib tug qhib Circuit Court fuse, hloov los yog Circuit Court breaker. Xauv thiab tag lub cuab yeej hauv kev sim.
3. Tshem tawm cov ceg ntoo, cov hmoov txhuas hauv av, thiab tag nrho lwm yam khoom siv los ntawm lub tsev nyob rau hauv kev sim.
4. Tshem tawm tus neeg xyuas pib capacitance ua ntej thiab tom qab kuaj.
3. Cov teeb meem xav tau kev saib xyuas
1. Tshawb xyuas cov dej ntws tawm los ntawm txhua lub fuses, switchgear thiab Circuit Court breakers nyob rau hauv lub de-energized circuit. Cov dej ntws tawm tuaj yeem ua rau tsis sib xws thiab nyeem ntawv yuam kev.
2. Txij li thaum lub ntsuas yuav tsim ib qho arc thaum lub rwb thaiv tsev puas lawm, thov tsis txhob siv lub rwb thaiv tsev tester nyob rau hauv ib qho chaw txaus ntshai los yog tawg.
3. Tsis txhob siv cov ntsuas hluav taws xob tiv thaiv hluav taws xob.
4. Thov siv cov hnab looj tes roj hmab insulating nrog tawv tiv thaiv thaum txuas cov xov hlau kuaj.
4. Txoj cai tswj xyuas
(1) Thaum cov cuab yeej raug teeb tsa thiab kho tshiab
Nws yuav zam tsis txhob cuam tshuam kev xaim hluav taws xob thiab cov khoom siv tsis zoo hauv lub cev, ua kom muaj kev txhim kho zoo, thiab tiv thaiv hluav taws xob los yog khoom siv los ntawm kev ua kom hluav taws.
(2) Tshem tawm kev phom sij
Los ntawm kev ua qhov ntsuas hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob ntawm cov xaim tam sim no thiab cov xaim hauv av, cov neeg saib xyuas tuaj yeem tshem tawm qhov ua rau muaj kev phom sij luv lossis luv luv rau hauv av.
(3) Tiv thaiv
Kev saib xyuas cov txiaj ntsig zoo ntawm cov rwb thaiv tsev tsis tu ncua uas siv lub rwb thaiv tsev multimeter tuaj yeem muab cov ntaub ntawv hais txog lub xeev ntawm cov rwb thaiv tsev degradation thiab xyuas kom lub sijhawm kho lossis hloov khoom siv.
