Stainless hlau cartridge tso cua sov yog cov khoom siv hluav taws xob uas siv dav hauv cov khoom siv thiab cov khoom siv hauv tsev. Lawv cov rwb thaiv tsev kev ua tau zoo yog cuam tshuam ncaj qha rau kev ua haujlwm kev nyab xeeb, ua rau kev ntsuas hluav taws xob tsis tu ncua tseem ceeb heev. Tsab ntawv xov xwm no qhia txog cov txheej txheem kev ntsuas hluav taws xob, kev ceev faj, thiab kev daws teeb meem rau cov teeb meem tsis zoo rau stainless hlau cartridge rhaub.
I. Qhov tseem ceeb ntawm kev ntsuas rwb thaiv tsev
Thaum lub tshuab rhaub dej kub ua haujlwm, tam sim no dhau los ntawm cov xaim hluav taws xob sab hauv los ua kom muaj cua sov, thaum lub plhaub sab nrauv (feem ntau stainless hlau) nyob rau hauv kev sib cuag ncaj qha nrog rau sab nraud ib puag ncig. Zoo rwb thaiv tsev kom ntseeg tau tias:
1. Kev tiv thaiv ntawm hluav taws xob poob siab tshwm sim los ntawm tam sim no to.
2. Kev zam ntawm kev pheej hmoo hluav taws kub vim yog luv luv Circuit Court.
3. Kev ua tau zoo thiab lub neej ntev ntawm lub tshuab cua sov.
4. Ua raws li cov qauv kev nyab xeeb hluav taws xob thiab cov kev cai tswj hwm.
II. Kev Npaj Ua Ntej Kev Xeem
1. Kev Npaj Cov Khoom Siv Xeem:
Rwb thaiv tsev Resistance Tester (Megohmmeter): Nws raug nquahu kom xaiv lub megohmmeter nrog 500V lossis 1000V DC tso zis.
Multimeter: Rau kev kuaj ua ntej.
Thermometer: ntsuas ambient kub.
Hygrometer: ntsuas ambient humidity.
Cov cuab yeej ntxuav: Tsis muaj dej cawv, lint -dawb ntaub, thiab lwm yam.
2. Environmental Requirements:
Ambient Kub: 15-35℃(zoo tagnrho kuaj ntau).
Tus txheeb ze humidity: Tsis pub tshaj 85%.
Qhov chaw kuaj yuav tsum qhuav thiab zoo -ventilated.
Tsis txhob muaj zog electromagnetic cuam tshuam.
3. Kev npaj lub rhaub dej kub hauv kev sim:
Xyuas kom lub rhaub yog txias tag rau hauv chav tsev kub.
Ntxuav lub rhaub dej kom tshem tawm cov kab mob xws li roj thiab dej stains.
Tshawb xyuas lub tshuab rhaub kom paub meej tias tsis muaj kev puas tsuaj.
Disconnect tag nrho cov kab hluav taws xob sab nraud.
III. Cov kauj ruam tshwj xeeb rau kev ntsuas rwb thaiv tsev
1. Kev Tshawb Fawb Ua Ntej:
Siv lub multimeter rau qhov kev ntsuam xyuas thawj zaug:
Teem lub multimeter mus rau qhov kev ntsuas ntsuas hom.
Ntsuas qhov kev tawm tsam ntawm cov cua sov ua kom sov thiab lub plhaub sab nraud.
Nquag, nws yuav tsum tso saib "OL" (Over Limit) lossis tus nqi siab heev.
Yog tias qhov ntsuas qhov ntsuas qis qis tau tshwm sim, tej zaum yuav muaj qhov cuam tshuam ntawm rwb thaiv tsev.
2. Megohmmeter Test:
Kauj Ruam 1: Xaiv qhov tsim nyog Voltage:
Ua hauj lwm Voltage Tsawg dua los yog sib npaug rau 36V: Xaiv 250V ntau yam.
Ua hauj lwm Voltage 36V - 500V: Xaiv 500V ntau yam.
Ua hauj lwm Voltage> 500V: Xaiv 1000V ntau yam.
Kauj Ruam 2: Txuas Kev Xeem Leads:
Txuas lub megohmmeter's "L" davhlau ya nyob twg mus rau lub rhaub dej kub.
Txuas lub "E" davhlau ya nyob twg rau lub rhaub lub hlau sheath / casing.
Xyuas kom muaj kev sib cuag zoo; siv cov clamps yog tias tsim nyog.
Kauj Ruam 3: Pib Kev Xeem:
Nias lub pob xeem lossis tig tus kov (nyob ntawm hom megohmmeter).
Khaws ib qho kev sib hloov ceev (rau phau ntawv crank hom).
Saib xyuas thiab sau cov nqi hluav taws xob tiv thaiv ntawm 15 vib nas this thiab 60 vib nas this.
Kauj Ruam 4: Xaus Kev Xeem:
Disconnect qhov kev xeem ua ntej, ces nres lub megohmmeter.
Tshem tawm lub rhaub, tshwj xeeb tshaj yog rau siab - muaj peev xwm units.
3. Txhais cov qhabnias xeem:
Raws li cov qauv xws li GB / T 1234-2012 (Suav Teb Chaws Tus Qauv):
Txias rwb thaiv tsev Resistance: Ntau dua los yog sib npaug rau 50 MΩ (ntawm chav tsev kub).
Kub rwb thaiv tsev Resistance: Ntau dua los yog sib npaug rau 1 MΩ (ntawm kev khiav hauj lwm kub).
Absorption Ratio (R60s / R15s): Ntau dua lossis sib npaug rau 1.3 qhia tias muaj kev rwb thaiv tsev zoo.
IV. Kev sim cov txheej txheem rau cov xwm txheej tshwj xeeb
1. Kub-State Insulation Test:
Fais fab lub rhaub rau nws qhov ntsuas kub ua haujlwm.
Ua qhov ntsuas hluav taws xob tam sim tom qab hluav taws xob tawm (saib qhov siab -kev ceev faj txog qhov kub thiab txias).
Ua kom tiav qhov kev xeem kom sai li sai tau (hauv 30 vib nas this).
2. Kev sim hauv qhov chaw ntub dej:
Muab lub rhaub tso rau hauv ib puag ncig nrog 85% txheeb ze av noo rau 24 teev.
Ua qhov kev ntsuas rwb thaiv tsev tam sim tom qab tshem tawm.
Cov txheej txheem dhau los tuaj yeem txo qis kom tsim nyog tab sis yuav tsum tsis txhob <10 MΩ.
3. Ntsuas Tom Qab Ntev - Lub Sij Hawm Cia:
Ua ntej ua qhov qis -voltage pre-test (piv txwv li, 250V).
Ua mus rau tus qauv ntsuas hluav taws xob nkaus xwb yog tias tsis pom qhov txawv txav.
Yog tias xav tau, ua qhov txheej txheem "ua kom" (tsawg- daim ntawv thov hluav taws xob hluav taws xob rau cua sov).
V. Tej teeb meem thiab kev daws teeb meem
1. Tsawg Insulation Resistance:
Tej Yam Ua Tau: Cov kab mob ntawm qhov chaw; nrog magnesium oxide hmoov nqus dej; aging rwb thaiv tsev cov ntaub ntawv; luv Circuit Court vim mechanical puas.
Kev daws: ntxuav thiab qhuav kom huv si; qis-kub ci (100-120℃rau 2-4 teev); hloov cov khoom puas.
2. Cov ntawv nyeem tsis ruaj khov:
Tej Yam Ua Tau: Kev sib txuas tsis zoo; ib puag ncig cuam tshuam; faulty megohmmeter.
Kev daws: Tshawb xyuas cov kev sib txuas ua ke; hloov qhov kev xeem ib puag ncig; calibrate lub ntsuas ntsuas.
3. Abnormal Absorption Ratio:
Tej Yam Ua Tau: Cov khoom siv rwb thaiv tsev ntub dej; internalized tsis xws luag; txoj kev kuaj tsis raug.
Kev daws: Qhuav lub rhaub; ua segmental xeem los nrhiav qhov txhaum; re- ua qhov kev xeem raws li cov txheej txheem tsim nyog.
VI. Kev Tiv Thaiv Kev Nyab Xeeb
1. Kev ntsuam xyuas yuav tsum tau ua nrog lub hwj chim txiav.
2. Khaws ib qho chaw nyab xeeb thaum lub sij hawm ntsuas siab -voltage.
3. Xyuas kom txaus tso tawm ntawm lub rhaub tom qab kev sim.
4. Tsis txhob kov cov ntsiab lus xeem nrog txhais tes.
5. Ceev faj ntxiv rau hauv qhov chaw ntub dej.
6. Tsis txhob kuaj tam sim yog tias pom muaj qhov txawv txav.
VII. Cov ntaub ntawv soj ntsuam thiab kev pom zoo saib xyuas
1. Test Record Content:
Xeem hnub thiab sijhawm.
ambient kub thiab humidity.
Test voltage.
Rwb thaiv tsev qhov tseem ceeb (ntawm 15s thiab 60s).
Muab xam piv piv.
Tester tus kos npe.
Lus Ceeb Toom (pib piav txog tej yam tsis zoo).
2. Cov Lus Qhia Txog Kev Kho Mob:

Kev siv tsis tu ncua: Kuaj txhua 3-6 lub hlis.
Ib puag ncig hnyav: Ntsuas txhua hli.
Tom qab ntev - lub sij hawm cia: Re- sim ua ntej siv.
Tom qab kho: Yuav tsum tau rov qab- sim.
VIII. Xaus
Kev ntsuas rwb thaiv tsev rau stainless hlau cartridge tso cua sov yog txheej txheem tseem ceeb rau kev ua kom muaj kev nyab xeeb hluav taws xob. Los ntawm kev ua raws li cov txheej txheem kev soj ntsuam, siv cov cuab yeej raug, thiab txheeb xyuas cov ntaub ntawv kom raug, cov kev phom sij tuaj yeem raug txheeb xyuas tam sim los tiv thaiv kev nyab xeeb. Nws raug nquahu kom cov neeg siv tsim cov ntaub ntawv xeem, ntsuas kev ua haujlwm tsis tu ncua, thiab xyuas kom muaj kev nyab xeeb ntawm cov cua sov. Tsis tas li ntawd, nrog rau kev txhim kho thev naus laus zis, kev txiav txim siab tuaj yeem muab rau kev siv cov thev naus laus zis saib xyuas hauv online ntau dua rau qhov tiag - lub sijhawm tiv thaiv kev soj ntsuam.
