Xob laim worgulse withstand ntsuas yog ib txoj kev xeem siv los ntsuas cov khoom siv hluav taws xob hauv cov roj hluav taws xob hauv hluav taws xob. Nws simulates qhov kev cuam tshuam ntawm xob laim poob siab ntawm cov khoom siv kom ntseeg tau tias cov cuab yeej tuaj yeem ua haujlwm nyab xeeb hauv kev teeb meem lossis lwm yam kev hloov pauv hloov pauv.
1. Kuaj lub hom phiaj
Tshawb xyuas cov rwb thaiv tsev rwb thaiv tsev muaj zog: sim cov rwb thaiv tsev kev ua haujlwm ntawm cov khoom siv hluav taws xob ua kom ntseeg tau tias nws tuaj yeem tiv taus hluav taws xob lossis lwm yam kev hloov pauv.
Txheeb xyuas cov cuab yeej kev ntseeg tau: Tshawb nrhiav cov cuab yeej siv hluav taws xob muaj peev xwm los ntawm kev xeem kom tsis txhob muaj kev ua haujlwm.
Raws li cov qauv kev cai: ua raws li cov qauv hauv ntiaj teb thiab hauv tebchaws (xws li IEC, GB, thiab lwm yam) rwb thaiv hluav taws xob ua kev ua haujlwm yuav tsum tau ua.
2. Kuaj hauv paus ntsiab lus
Xob laim nrog cov kev ntsuas voltage yog thov rau cov tshuaj insulated ntawm cov tshuaj ntsuam qib (feem ntau 1.2 / 50μs waveForm) uas simulates txoj kev xob laim laim. Cov kauj ruam tshwj xeeb suav nrog hauv qab no;
WaveForm ntau tiam: Siv ib qho kev siv hluav taws xob tsim hluav taws xob los tsim cov qauv xob laim immulse pab pawg.
Daim ntawv thov kev voltage: kev ntsuas siab siab pulses tau thov rau qhov insulated ib feem ntawm lub cuab yeej.
Saib xyuas cov ntaub ntawv: Saib seb cov cuab yeej siv puas muaj kev puas tsuaj los yog sau cov ntaub ntawv ntsuas.
3. Kuaj Hom
Txheem xob laim ua poob siab: 1.2 / 50μs WaveForm yog siv los simulate cov yam ntxwv ntawm xob laim poob siab.
Kev Ua Haujlwm Kev Ua Haujlwm Kev Ua Haujlwm: Simulate Kev Ua Haujlwm Txheej Txheem, feem ntau nrog cov nthwv dej ntawm 250 / 2500μs.
Kev ntsuas polarity cuam tshuam: qhov cuam tshuam zoo thiab tsis zoo voltages tau siv los ntsuas cov rwb thaiv tsev insulation to taub.
4. Kuaj cov khoom siv
Impulse voltage generator: tsim cov hluav taws xob siab siab.
Diam photion: ntsuas cov ntawv thov voltage muaj nuj nqis.
Oscilloscope: Cov ntaub ntawv voltage WaveForm thiab ntaus ntawv teb.
Kuaj cov khoom: xws li transformers, cable, hloov pauv, thiab lwm yam khoom siv hluav taws xob.
5. Kuaj cov qauv
Xob laim immulse withstandy kev ntsuas thiab cov qauv hauv tebchaws, xws li:
Iec {60060-1: Heev voltage chant kev qhia.
GB / T 16927.1: Tuam Tshoj tus qauv hauv lub teb chaws, cov hluav taws xob siab tshaj tawm Technology.
IEEE C62.41: Txhais thiab kev thov ntawm laim hluav taws xob cov vagforms.
6. Kev tshuaj ntsuam ntawm cov ntawv xeem
Cov Qauv dhau: Cov khoom siv tsis tawg lossis nyem dua hauv kev sim, thiab cov kev ua haujlwm rwb thaiv tsev coj cov tseev kom muaj.
Lub sijhawm tsis muaj mob: Yog tias cov khoom siv tau muaj kev puas tsuaj lossis rwb thaiv tsev kev puas tsuaj, nws yog qhov tsim nyog los tshuaj xyuas qhov ua rau thiab txhim kho tus qauv.
