National Standards For DC Withstand Voltage Testers

IEC {{0}}}: 1989 High voltage test technology Part 1: General test requirements DLT 848 adopts nruab nrab zaus voltage doubler circuit. Lub tshuab hluav taws xob DC tshiab siv PWM pulse width modulation technology thiab high-power IGBT li. Raws li txoj kev xav ntawm electromagnetic compatibility, kev tiv thaiv tshwj xeeb, kev sib cais thiab kev ntsuas hauv av tau txais yuav. DC high voltage xeem yog high-zoo, portable thiab muaj peev xwm tiv taus voltage tawm yam tsis muaj kev puas tsuaj. DC high voltage generator muaj ntau yam kev tiv thaiv kev ua haujlwm, xws li: tsis tshua muaj hluav taws xob overcurrent, tsis tshua muaj hluav taws xob overvoltage, high voltage overcurrent, high voltage overvoltage, xoom kev tiv thaiv, ungrounded tiv thaiv, thiab lwm yam. Kev ua txhaum sampling, nrog lub sijhawm ua haujlwm ntawm nanoseconds, thiab cov khoom siv kho qhov muag yog nanoseconds. Lub sijhawm ua haujlwm feem ntau yog 10 microseconds kom kaw tag nrho DC lub ntsiab Circuit Court. Lub laub teeb liab ceev ceev kev tiv thaiv siv lub sensor tshwj xeeb rau kev kuaj ntawm qhov tso zis kawg, thiab lub sij hawm cov tshuaj tiv thaiv yog nanoseconds. Los ntawm nanosecond optical cais cov ntsiab lus thiab nanosecond analog keyboards, lub teeb liab ntawm lub hwj chim amplifier Circuit Court raug txiav tawm hauv 2 microseconds nyob rau hauv tag nrho cov txheej txheem, xyuas kom meej tias lub hwj chim ntaus ntawv tsis puas nyob rau hauv cov ntaub ntawv ntawm cov zis luv luv Circuit Court. Nws yog hais txog cov khoom siv hluav taws xob high-voltage feem ntau yog siv rau hauv kev rwb thaiv tsev thiab kev kuaj pom. Tam sim no tsis muaj qhov sib txawv nruj ntawm high-voltage fais fab mov thiab high-voltage generator. DC high-voltage generator yog thawj zaug hauv kev lag luam los txais yuav cov qauv segmented, uas tuaj yeem siv rau ob qho tib si high voltage thiab qis voltage theem, thiab nws qhov tseeb tseem tsis hloov pauv. Noj 100/200kV/2mA muab faib ua ob ntu ua piv txwv, thaum ib ntu siv, 100kV / 2mA tuaj yeem siv tau, uas tuaj yeem siv rau DC high-voltage kuaj cov khoom siv hluav taws xob hauv 35kV thiab hauv qab no systems. Lub sijhawm no, qhov tseeb ntawm qhov ntsuas tuaj yeem lav kom tsis txhob muaj tus nees loj rub lub laub me me; Thaum siv ob ntu, 200kV / 2mA tuaj yeem siv tau. Nws tuaj yeem siv rau 220kV ntu, 110kV thiab hauv qab zinc oxide xob laim ntes DC kuaj thiab kab txuas txuas txuas DC tiv thaiv kev ntsuas hluav taws xob. Nws ua tiav ob lub hom phiaj hauv ib lub tshuab, ua kom yooj yim rau kev siv ntawm cov neeg siv ntawm qhov chaw. Nws yog tsuas yog siv los kawm txog lub zog rwb thaiv tsev ntawm cov khoom siv hluav taws xob DC precision thiab cov khoom siv hluav taws xob hloov hluav taws xob thiab cov ntaub ntawv rwb thaiv tsev nyob rau hauv DC high voltage, corona thiab ion ntws ntawm DC cov kab hluav taws xob thiab lawv cov teebmeem, thiab ua cov kev ntsuas tam sim no ntawm AC thiab DC fais fab. khoom siv. Tsis tas li ntawd, nws kuj tseem siv tau los ua lub zog rau lwm yam khoom siv high-voltage test xws li impulse voltage generators, impulse tam sim no generators, oscillation circuits, thiab lwm yam. Nws kuj yog siv dav hauv lwm yam kev tshawb fawb thiab thev naus laus zis, xws li lub cev ( accelerators, electron microscopes, thiab lwm yam), cov khoom siv kho mob hluav taws xob (X-rays), kev siv hluav taws xob (khoom siv los nag, electrostatic spraying, thiab lwm yam), lossis kev sib txuas lus hauv hluav taws xob (xov tooj cua, xov tooj cua), thiab lwm yam. ZGF DC high-voltage generator adopts nruab nrab-frequency rectification thiab filtering technology los daws cov shortcomings ntawm loj ripple coefficient thiab tsis ruaj tsis khov waveform ntawm industrial zaus DC high-voltage generator. Cov khoom ua tau raws li qhov yuav tsum tau ua ntawm lub teb chaws fais fab kev lag luam tus qauv ZGF24003-90 "Txhua yam kev mob rau DC High Voltage Generators DL/T 848.1-2004", thiab yog dav siv nyob rau hauv DC withstand voltage test thiab cov xau tam sim no ntawm cov khoom siv hluav taws xob, thiab tshwj xeeb tshaj yog nruab nrog kev ua haujlwm ntawm kev ntsuas qhov hluav taws xob U1mA hauv qab 1mA thiab cov xau tam sim no hauv qab 0.75U1mA ntawm zinc oxide xob laim ntes. Kev tshawb fawb tshiab, tsim thiab tsim cov khoom siv thev naus laus zis tshiab yog tsim rau DC high voltage xeem ntawm zinc oxide xob laim ntes, sib nqus tshuab ntes, fais fab cable, lub tshuab hluav taws xob, transformer, hloov thiab lwm yam khoom siv hauv lub tuam tsev fais fab, lub tuam tsev fais fab ntawm cov chaw tsim khoom thiab cov mines, cov chaw tshawb fawb tshawb fawb, kev tsheb ciav hlau, kev lag luam tshuaj lom neeg, cov chaw tsim hluav taws xob, thiab lwm yam, thiab yog cov khoom siv hloov pauv zoo tshaj plaws hauv lub xyoo pua tshiab. VLF 0.1HZ ultra-low zaus high voltage generator ua ke niaj hnub digital zaus hloov dua siab tshiab thev naus laus zis thiab txais kev tswj hwm microcomputer. Boosting, bucking, ntsuas thiab tiv thaiv yog tag nrho automated. Thiab phau ntawv kev cuam tshuam tuaj yeem nqa tawm thaum lub sij hawm tsis siv neeg boosting txheej txheem. Vim nws yog hluav taws xob tag nrho. Nws tuaj yeem siv dav hauv AC tiv thaiv qhov ntsuas hluav taws xob ntawm cov cables, tig lub cev muaj zog thiab lub zog hluav taws xob. Lub ZGF digital DC high voltage generator siv cov thev naus laus zis tshiab, cov ntaub ntawv tshiab thiab cov khoom siv tshiab los ntawm xyoo 1990. Nws muaj cov yam ntxwv ntawm lub zog tso zis loj, me me thiab lub teeb yuag. Nws muaj kev ruaj ntseg overvoltage, overcurrent thiab xoom-txoj hauj lwm kaw kev tiv thaiv kev ua haujlwm, nrog 0.75 zaug voltage latching muaj nuj nqi, thiab yog nruab nrog lub sij hawm relay, uas tuaj yeem teem lub sij hawm lub tswb thaum lub sij hawm kuaj. Tag nrho cov cuab yeej yog ib qho yooj yim nqa, yooj yim rau kev khiav lag luam, muaj kev nyab xeeb thiab txhim khu kev qha, thiab tshwj xeeb tshaj yog haum rau cov kev ntsuam xyuas ntawm qhov chaw hauv lub hwj chim sector.
