Muaj plaub qhov siv tau siv rau cov zis hluav taws xob, suav nrog lub thawv hluav taws xob voltetic, suav nrog cov qauv hluav taws xob voltermeter, xws li Milliamp meter txujci, thiab dbny- S withstand kev kuaj xyuas tsim los ntawm dingsheng fais fab ntsuas ntawm cov khoom siv hluav taws xob ntawm ntau cov khoom siv hluav taws xob, cov ntaub ntawv insulating thiab insulating qauv qauv. Fithstand voltage tester tuaj yeem hloov kho qhov loj me ntawm kev ntsuas voltage thiab teeb lub neej tawg. Tsab ntawv no kom tau txais ntau cov zis voltage kuaj pom raws li kev txawj ntawm cov kev cai pov thawj.
4 txoj kev kuaj pom rau cov zis hluav taws xob ntawm cov withstand ntsuas
1. Electrostatic VoltMeter Txoj Kev
2. Voltage transformer txoj kev
Peb, hluav taws xob sib zog nrog cov qauv voltmeter
Plaub, High Resistator Box nrog Milliameter Txoj Kev
Raws li cov txheej txheem saum toj no 4 thiab cov tswv yim, cov kev tshawb pom cov qauv tsim ntawm cov qauv txheem hluav taws xob thiab qhov kev ua txhaum cai yuav tsum tau ua kom tau raws li cov cai pov thawj. Tsis tas li ntawd, cov qauv ntawm cov neeg tiv thaiv kev tawm tsam (cov khoom siv) muaj kev nyuaj, thiab cov kev ntsuas ntawm nws cov zis ntau tsis txwv rau saum plaub. Tsuas yog cov kev cai tswjfwm thiab cov cai tswjfwm cov txheej txheem tam sim no, cov qauv kev pab cuam tshuam nrog cov ntaub ntawv tso cai tau muab tso rau cov zis siv tau muab tso rau cov zis rau cov neeg ua haujlwm muaj feem xyuam.
1. Nrog siv hluav taws xob ntsuas
Nrog rau voltage tester kuj tseem hu ua hluav taws xob rwb thaiv tsev muaj zog teser lossis dielectric lub peev xwm tester. Kev sib txuas lus lossis DC lub zog hluav taws xob tsis tu ncua ntawm lub live cov khoom siv hluav taws xob thiab cov plhaub tsis muaj hluav taws xob (feem ntau ntawm cov khoom siv hluav taws xob rwb thaiv tsev. Thaum lub sijhawm ua haujlwm ntev ntawm cov khoom siv hluav taws xob, tsis tas yuav tsum lees txais cov nyhuv ntawm cov kev siv hluav taws xob ntxiv rau lub sijhawm luv luv thaum lub sijhawm ua haujlwm (tus nqi overvoltes yuav yog ob peb Lub sij hawm siab dua li tus nqi ntawm cov kev ua haujlwm voltage ntxiv.). Nyob rau hauv cov nyhuv ntawm cov hluav taws xob, cov qauv sab hauv ntawm cov khoom siv hluav taws xob hauv hluav taws xob yuav hloov. Thaum cov kev siv overvoltage mus txog ib qho nqi, cov rwb thaiv tsev ntawm cov khoom yuav tawg, cov khoom siv hluav taws xob yuav tsis ua haujlwm ib txwm, thiab tus neeg teb xov tooj yuav tsis muaj hluav taws xob, muaj kev phom sij rau tus kheej.
1. Cov qauv thiab kev sib xyaw ntawm withstt voltage kuaj
(1) Powering Tshooj
Nws yog tsim ntawm voltage regulating hloov pauv, kauj ruam hloov pauv thiab kauj ruam-nce kev siv fais fab thiab thaiv.
Lub 220V voltage yog muab rau thiab cov thaiv kev hloov yog ntxiv rau qhov kev tswj hwm hloov chaw thiab cov kev tswj hwm kev hloov pauv hloov tau txuas nrog txoj kev txhawb nqa. Cov neeg siv tsuas yog yuav tsum tau xa cov regulator uas tswj cov zis hluav taws xob ntawm cov kauj ruam hloov.
(2) tswj ib feem
Tam sim no kev kuaj tus qauv, lub sijhawm Circuit Court thiab tswb Circuit Court. Thaum txoj kev tswj hwm tau txais lub teeb liab pib, qhov ntsuas tau tam sim ntawd tig rau kev ua haujlwm muaj zog. Thaum cov ntsuas hluav taws xob tam sim no tau ntau tshaj li cov nqi teeb thiab ib qho kev pom zoo thiab pom tau pom kev, lub boost Circuit Coalruit Fais Fab Khoom yog tam sim ntawd thaiv. Thaiv lub boost loop fais fab mov tom qab tau txais rov pib dua lossis sijhawm nce teeb liab.
(3) Flash Circuit
Lub flasher flashes cov zis voltage muaj nuj nqis ntawm cov kauj ruam hloov pauv. Tus nqi tam sim no ntawm qhov kev ntsuas tam sim no thiab lub sijhawm muaj nuj nqis ntawm lub sijhawm Circuit Court feem ntau suav.
(4) Qhov saum toj no yog cov qauv ntawm cov tsoos nrog cov tshuaj voltage. Nrog rau hluav taws xob thev naus laus zis thiab ib leeg nti, khoos phis tawj tau raug tsim kho sai; Cov kev pabcuam tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv tau tseem tau tsim sai sai nyob rau xyoo tsis ntev los no. Qhov sib txawv ntawm cov kev pab cuam voltage withst fortinger thiab tsoos nrog voltage satter feem ntau yog lub peev xwm. Lub High-voltage bogy boost ntawm lub programmable withstalt los ntawm cov ntsiab lus voltage yog tsim los ntawm kev tswj hwm ntawm ib-nti lub computer thiab tom qab ntawd nthuav dav thiab txhawb nqa los ntawm lub hwj chim nthuav dav Circuital Circuit Court, thiab cov zis hluav taws xob muaj txiaj ntsig tseem tswj hwm los ntawm ib qho nws tau tswj los ntawm lub hauv paus ntsiab lus, thiab lwm qhov ntawm lub hauv paus ntsiab lus tsis txawv ntawm tus ntsuas kev ntsuas siab.
2. Xaiv ntawm withstt voltage tester
Qhov tseem ceeb tshaj plaws hauv kev xaiv Fallage voltage voltage yog ob txoj cai. Qhov ntau tshaj tawm cov zis voltage thiab siab tshaj plaws lub tswb tam sim no muaj txiaj ntsig yuav tsum muaj ntau dua cov voltage muaj nuj nqis thiab tswb tam sim no koj xav tau. Feem ntau, tus qauv ntawm cov khoom ntsuas cov khoom muag cov khoom siv ntawm cov ntawv thov ntawm cov neeg voltage ntau thiab lub tswb los txiav txim cov nqi tam sim no. Piv txwv tias ntau dua cov ntawv thov voltage, qhov ntau dua lub zog ntawm cov kauj ruam kauj ruam hloov ntawm Fallage Voltage yog qhov yuav tsum tau ua. Feem ntau, lub zog ntawm cov kauj ruam kauj ruam hloov ntawm Fallage Voltage yog 0.2Kva, 1kVa, thiab lwm yam. Qhov siab tshaj plaws tuaj yeem nce kaum txhiab lub volts. Lub tswb ntau tshaj plaws yog 500ma-1000mA-1000MA, thiab lwm yam yog li ntawd, ob txoj cai no yuav tsum tau them rau thaum xaiv lub ntsuas siab. Yog tias lub zog loj dhau lawm, nws yuav piam. Yog tias lub zog me me dhau, tiv thaiv kev ntsuas volage tsis tuaj yeem raug txiav txim seb nws tsim nyog lossis tsis yog. Raws li cov cai hauv IEC414 lossis (GB6738-86), peb xav tias nws yog kev paub ntau ntxiv los xaiv lub zog hluav taws xob ntawm kev tiv thaiv voltage. "Ua ntej, kho cov zis hluav taws xob ntawm wallage meter rau 50% ntawm cov nqi tswj hwm, thiab tom qab ntawd txuas cov khoom ntsuas. Thaum cov neeg soj ntsuam voltage poob yog tsawg dua 10% ntawm cov hluav taws xob muaj nuj nqis, nws tau xav tias lub zog ntawm kev tiv thaiv voltage yog txaus siab. "Qhov ntawd yog, kwv yees tias tus nqi hluav taws xob feem ntau ntawm cov khoom siv voltage ntawm cov khoom siv voltage rau 1500 volts thiab tom qab ntawd txuas cov khoom ntsuas. Nws tau kwv yees tias tus nqi ntawm cov zis hluav taws xob poob ntawm Fallage Voltage lub sijhawm no tsis yog ntau tshaj 150 volts, ces lub zog ntawm kev tiv thaiv voltage yog txaus. Muaj kev faib tawm ntawm lub live nyob ntawm ib feem ntawm cov khoom kuaj thiab lub khauj khaum. Lub capacitor muaj Cx caportitions, thiab thaum ib qho kev sib txuas lus yog thov rau ob qho kawg ntawm Cx Capacitor, yuav tau kos duab.
