Cov Qauv Hluav Taws Xob thiab cov kauj ruam ntsuas ntawm cov hluav taws xob tiv thaiv
Qhov thiaj li hu ua nrog cov twj voltage, raws li nws muaj nuj nqi yog: Thov nws lub zog ua haujlwm rau insulator ntawm insulator ntawm cov khoom siv sim rau a Lub sij hawm teev tseg ntawm lub sijhawm, thiab cov hluav taws xob thov rau nws tsuas yog tsim cov xau me me tam sim no, yog li cov rwb thaiv tsev zoo dua. Qhov kev xeem yog muaj peb tus qauv: Kev tswj kev tswj hwm hluav taws xob module, teeb liab mus kuaj thiab mob module thiab kev tswj lub computer. Xaiv ob txhais tau ntawm cov ntsuas hluav taws xob: Cov zis loj voltage muaj nuj nqis thiab lub tswb loj tam sim no tus nqi.
Kev sib ntaus hlau ntawm withstand voltage kuaj:
1. Txheeb xyuas thiab paub meej tias lub zog tseem ceeb hloov ntawm Fallage Satter yog nyob rau hauv "off" txoj hauj lwm
2. Tsuas yog cov qauv tsim tshwj xeeb ntawm cov twj paj nruag, txhua qhov chaw tso khoom hlau yuav tsum yog cov av khov kho
3. Txuas cov xov hlau lossis cov terminals ntawm txhua lub zog cov tswv yim terminals ntawm cov khoom siv sim
4. Kaw tag nrho cov fais fab hloov, rov qab, thiab lwm yam ntawm cov khoom siv kuaj
5. Kho cov kev sim voltage ntawm tus withstand voltage tester rau xoom
6. Txuas lub siab voltage tso kab kab ke (feem ntau liab) ntawm lub voltage teser rau lub hwj chim tawm tswv yim
7.
8. Kaw lub hwj chim tseem ceeb ntawm Fallage Tester thiab maj mam mus rau theem voltage ntawm teser rau cov nqi xav tau. Feem ntau, txoj kev txhawb zog yuav tsis pub tshaj 500 v / sec
9. Ua kom ntsuas qhov ntsuas hluav taws xob rau lub sijhawm tshwj xeeb
10. Qiv qeeb txoj kev ntsuam xyuas voltage
11. Kaw lub hwj huam tseem ceeb hloov ntawm Fallage Tester. Disconnect Lub Siab Voltage Outpece Kab ntawm Voltage Tester Ua ntej, thiab tom qab ntawd lub Circuit Coal galk ntawm cov voltage kuaj
Cov xwm txheej nram qab no qhia tau tias cov khoom kuaj sim tsis tuaj yeem xeem dhau:
* Thaum xeem voltage tsis nce mus rau cov qauv hluav taws xob tshwj xeeb lossis cov hluav taws xob hluav taws xob tsis txhob siv
* Thaum lub ntsuas hluav taws xob muaj cov phiajcim ceeb toom
Nws yuav tsum raug sau tseg tias vim muaj kev phom sij ntau rau hauv kev sim voltage, yuav tsum tau ua haujlwm tshwj xeeb thaum ntsuas.
Cov ntsiab lus hauv qab no xav tau kev saib xyuas tshwj xeeb:
* Nws yuav tsum tau hais meej tias tsuas tau cob qhia thiab cov neeg ua haujlwm uas muaj cai tuaj yeem nkag mus rau hauv qhov kev xeem ua haujlwm los ua haujlwm ntsuas
* Tsau thiab pom tseeb cov cim ceeb toom yuav tsum tso ib ncig ntawm thaj chaw xeem kom tiv thaiv lwm tus neeg tuaj yeem nkag mus rau thaj chaw txaus ntshai
* Thaum kuaj, txhua tus neeg ua haujlwm, suav nrog tus neeg teb xov tooj, yuav tsum nyob deb ntawm kev ntsuas ntsuas thiab cov cuab yeej siv
* Tsis txhob kov cov zis kab ntawm kev sim ntsuas thaum nws tau pib
Cov kauj ruam xeem ntawm withstt voltage kuaj:
1. Tshawb xyuas seb cov cai "voltage ntawm" lub pob qhov rooj ntawm lub withstand ntsuas yog tig mus rau qhov kawg anticlockwise. Yog tias tsis yog, tig nws mus txog thaum kawg.
2. Ntsaws rau hauv lub hwj chim ntawm lub ntsuas thiab tig rau lub hwj chim hloov ntawm lub ntsuas.
3. Xaiv cov voltage uas tsim nyog: teeb lub voltage ntau hloov mus rau "5kv" txoj hauj lwm.
4. Xaiv qhov tsim nyog AC / DC voltage ntsuas iav: teeb tus "AC / DC" hloov mus rau "AC" txoj haujlwm.
5. Xaiv cov towage tsim nyog tam sim no: Teem lub to tam sim no tau hloov mus rau "2ma" txoj hauj lwm.
6, preset beakage tus nqi tam sim no: Nias lub "to tam sim no prese hloov" Preset tam sim no, thiab tam sim no ntsuas kev kub ntxhov tam sim no yog "1.500" ma. Txhawm rau kho thiab hloov pauv hloov mus rau "Kuaj" txoj haujlwm.
7. Sijhawm Sijhawm Sijhawm: Teem lub sijhawm "sijhawm / phau ntawv" hloov mus rau "Sijhawm" Txoj Haujlwm, Kho nws mus rau "30" vib nas this.
8.
9. Txuas lub siab ntsuas cov pas nrig siab, cov hlau xaim hluav taws xob thiab cov cuab yeej ntsuas (hauv av. ib feem, thiab lwm qhov kawg ntawm lub davhlau ya dav hlau siab
10. Pib txoj kev ntsuas tom qab xyuas cov ntsuas ntsuas thiab kev sib txuas.
11. Nias lub "pib" hloov ntawm qhov ntsuas, maj mam kho cov "pob qhov rooj rau kev txhawb nqa" 3.00 "KV ntawm lub Voltmeter. Nyob rau lub sijhawm no, tus nqi tam sim no ntawm lub todage ammeter tseem sawv. Yog hais tias tus nqi xau tam sim no muaj nuj nqis tshaj lub teeb tus nqi (1.5mA) thaum lub ntsuas ntsuas tau tsis muaj qhov tsis muaj lub ntsiab lus, nias lub "rov pib dua" hloov mus rau qhov ntsuas rau nws qub xeev. Yog hais tias lub xau dej tam sim no tsis tshaj cov nqi tsim, ntsuas yuav rov pib dua tom qab lub sijhawm sijhawm, qhia tau tias qhov ntsuas tau tsim nyog.
12Thaum txoj kev ntsuam xyuas cov chaw taws teeb ": ntxig tsib lub chaw taws teeb tsa ntawm cov twj tso chaw, thiab nias lub pob taws (thiab nias lub pob muag (thiab nias tus pas ntsuas) rau ntawm tus pas ntsuas ntsuas kom pib. Aviation ntsaws, tseem hu ua cov ntsaws qhov cub, yog siv dav hauv ntau qhov hluav taws xob hluav taws xob thiab ua lub luag haujlwm ntawm kev sib txuas lossis txiav tawm ntawm kev sib txuas los yog txiav tawm txawv txav.
