Rwb thaiv tsev multimeter ua hauj lwm hauv paus ntsiab lus thiab cov txheej txheem ua haujlwm
Txheej txheem cej luam: Lub rwb thaiv tsev multimeter yog cov cuab yeej ua haujlwm siv los ntawm cov kws tshaj lij los ua cov kev ntsuas 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 cuab yeej siv rau: txheeb xyuas 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 khoom siv. lub sijhawm, thiab txiav txim siab qhov ua rau muaj kev txhaum.
Qhov tseem ceeb ntawm Insulation Resistance Measurement
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 kev puas tsuaj thiab ua kom muaj txiaj ntsig zoo tshaj plaws. Nyob rau tib lub sijhawm, nws tseem tuaj yeem tshem tawm qhov tshwm sim ntawm hluav taws xob poob siab, hluav taws kub thiab lwm yam xwm txheej txaus ntshai, los tiv thaiv tus kheej kev nyab xeeb ntawm cov neeg ua haujlwm.
Rwb thaiv tsev kuj ntsuas txheej txheem
1. Ua ntej kuaj nrog lub ntsuas hluav taws xob rwb thaiv tsev, cov kws tshaj lij yuav tsum ua ntej ntsuas qhov ntsuas hluav taws xob, tam sim no thiab tsis kam.
2. Tom qab cov khoom siv hluav taws xob tawm, 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 khoom siv insulating los tsim cov nqi hluav taws xob tiv thaiv.
Kev Ua Haujlwm Zoo
(i) Ua ntej kuaj
1. Ua hauj lwm ntawm cov khoom siv hluav taws xob uas tsis muaj hluav taws xob nyob qhov twg los xij, siv cov txheej txheem kaw tawm / tagout tsim nyog
2. Xav tias lub voj voog nyob rau hauv kev sim yog muaj zog thiab siv cov cuab yeej tiv thaiv tus kheej tsim nyog thiab cov cuab yeej kev nyab xeeb.
3. Tshem tag nrho cov hniav nyiaj hniav kub thiab sawv ntawm cov roj hmab insulated sook.
(ii) Thaum kuaj
1. Tsis txhob txuas lub ntsuas hluav taws xob insulated 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. Tshem tawm cov khoom siv nyob rau hauv kev sim los ntawm kev qhib Circuit Court fuse, hloov lossis Circuit Court breaker. Xauv thiab tag lub chav nyob hauv kev sim.
3. Disconnect qhib Circuit Court conductors, grounding conductors, thiab tag nrho lwm yam khoom siv los ntawm chav tsev nyob rau hauv kev sim.
4. Discharge conductor capacitance ua ntej thiab tom qab kuaj.
