Ultra-Low Frequency Withstand Voltage Tester Ua Haujlwm Txoj Cai thiab Scope ntawm Daim Ntawv Thov
Lub ultra-low zaus withstand voltage tester yog ib qho tseem ceeb ntawm cov cuab yeej siv hauv kev lag luam hluav taws xob los txiav txim siab lub peev xwm ntawm hluav taws xob rwb thaiv tsev kom tiv taus qhov hluav taws xob nyob rau hauv qis zaus. Cov cuab yeej no tuaj yeem siv los ntsuas cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam khoom siv hluav taws xob.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ultra-low zaus withstand voltage tester yog raws li daim ntawv thov sib txawv ntawm AC voltage ntawm cov conductors ntawm hluav taws xob rwb thaiv tsev raug kuaj. Nws generates ib tug sine wave voltage xws li ntawm 0.1 Hz mus rau 1 Hz zaus. Qhov voltage amplitude tuaj yeem hloov kho, thiab qhov hluav taws xob waveform tuaj yeem pom ntawm qhov screen interface. Qhov voltage amplitude yog ib kauj ruam-tsawg adjustable, thiab cov cuab yeej los nruab nrog ib tug overvoltage thiab overcurrent tiv thaiv mechanism, kom muaj kev ruaj ntseg thaum lub sij hawm ntsuas voltage.
Lub tshuab generates voltage waveforms uas yuav ntsuas ntau yam hluav taws xob rwb thaiv tsev Cheebtsam 'voltage breakdown yam ntxwv. Qhov no ua kom ntseeg tau tias cov khoom siv tuaj yeem tiv taus qhov kev ntxhov siab tsawg zaus tsis muaj strain. Cov ntaub ntawv ntsuam xyuas tau los ntawm cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob tiv thaiv hluav taws xob tuaj yeem siv los ntsuas qhov zoo ntawm cov ntaub ntawv rwb thaiv tsev, thiab pab tswj cov khoom siv hluav taws xob zoo tsim, kev sim, thiab kev tsim cov theem.
Ultra-low zaus tiv taus voltage tester muaj ntau yam kev siv, xws li hauv cov hluav taws xob transformers, high voltage cables, transistors, capacitors, breakers, relays, thiab lwm yam khoom siv hluav taws xob. Nws yog ib qho tseem ceeb rau kev ntsuas ntsuas hauv kev tshawb fawb hauv hluav taws xob thiab rau kev daws teeb meem engineering.
Qhov tseeb, qhov hluav taws xob tsis tshua muaj hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob yog lwm txoj hauv kev rau lub zog zaus tiv thaiv qhov ntsuas hluav taws xob. Nyob rau hauv lub hwj chim zaus tiv taus qhov ntsuas hluav taws xob ntawm cov tshuab hluav taws xob loj thiab nruab nrab, lub cev muaj zog, lub zog hluav taws xob thiab lwm yam khoom siv, vim lawv cov peev txheej loj hauv cov txheej txheej rwb thaiv tsev, yuav tsum muaj lub peev xwm loj ntsuas transformer lossis resonance transformer. Qee yam ntawm cov cuab yeej loj no tsis tsuas yog hnyav thiab kim, tab sis kuj siv tsis yooj yim. Yuav kom daws tau qhov kev tsis sib haum xeeb no, txoj kev txo qhov kev sim ntau zaus thiab lub peev xwm ntawm qhov ntsuas hluav taws xob tau siv dav hauv ntiaj teb. Nws tau raug pov thawj los ntawm ntau xyoo ntawm txoj kev xav thiab kev xyaum hauv tsev thiab txawv teb chaws uas hloov lub zog zaus tiv thaiv qhov ntsuas hluav taws xob nrog 0.1Hz ultra-low zaus tiv thaiv qhov ntsuas hluav taws xob tsis tau tsuas yog muaj qhov sib npaug, tab sis kuj txo qis heev. ntim thiab qhov hnyav ntawm cov khoom siv, theoretically, lub peev xwm yog kwv yees li ib feem tsib ntawm lub zog zaus, thiab kev ua haujlwm yooj yim. Qhov no yog qhov laj thawj tseem ceeb vim li cas txoj kev no tau siv dav hauv cov tebchaws tsim.
Raws li qhov teeb meem tiag tiag ntawm Tuam Tshoj lub zog hluav taws xob, lub teb chaws txoj kev loj hlob thiab Reform Commission tau tsim cov qauv kev lag luam ntawm ultra-low zaus (0.1Hz) withstand voltage test method for 35kV and below XLPE insulated power cables. Xyoo 2004, kev lag luam tus qauv DL / T 849. Txawm hais tias DC qhov hluav taws xob tiv thaiv cov cuab yeej ntsuas muaj qhov zoo ntawm qhov me me, lub teeb yuag thiab tus nqi qis, DC voltage tiv thaiv kev ntsuas kuj yog qhov cuam tshuam tshaj plaws rau cov rwb thaiv tsev ntawm cov khoom kuaj. (saib Table 2) yog li ntawd, cov kev cai hauv teb chaws tshiab kawg ntawm kev tiv thaiv cov khoom siv hluav taws xob tau qhia meej tias DC high voltage tsis siv rau qhov ntsuas hluav taws xob tiv thaiv cov khoom siv hluav taws xob, thiab AC voltage withstand test yog pom zoo.
Lub cim tshiab ntawm 0.1Hz ultra-low zaus high voltage generator tsim los ntawm peb lub tuam txhab txais cov khoom siv hluav taws xob tshiab thiab qhov tseeb ARM7 ib leeg-chip thev naus laus zis, ntxiv txo qhov ntim thiab qhov hnyav ntawm cov khoom siv, kev ua haujlwm ruam, kev ua haujlwm ruaj khov dua, kov yeej qhov tsis txaus ntawm thawj tiam ntawm kev siv tshuab ua haujlwm, xws li kev pabcuam luv luv, kev ua haujlwm siab tsis zoo thiab ntim loj. Los ntawm kev xyaum ntau xyoo, ntau tus neeg siv tswv yim qhia tau hais tias: - 80kV ultra-low zaus high voltage technology yog ua nyob rau hauv lub teb chaws, nrog cov nqi siab tshaj!
Nyob rau hauv xaus, lub ultra-low zaus withstand voltage tester muaj ib tug high degree ntawm qhov tseeb thiab kev ntseeg tau. Nws muab cov ntaub ntawv tseem ceeb rau kev ntsuam xyuas cov khoom siv hluav taws xob thiab pab txhawb kev tsim cov khoom siv hluav taws xob zoo. Nws cov kev siv ntau yam hauv kev lag luam hluav taws xob ua rau cov cuab yeej no tau yooj yim rau ob qho tib si me me thiab loj ntsuas qhov ntsuas hluav taws xob.
