Residual Current Device Tester

Lub MOEORW-WKL15 Residual Current Device Tester yog tag nrho -featured test platform mob siab rau R&D, kev tshuaj xyuas ntau lawm, thiab kev tshuaj xyuas zoo ntawm cov khoom siv tiv thaiv tam sim no. Nws kuj tseem ua haujlwm raws li RCD tus yam ntxwv tester, lub chaw nres tsheb tiv thaiv kev tiv thaiv, lossis PCBA to tiv thaiv kev sib dhos debugging fixture. Tsim los ntawm Cortex M4 siab -kev ua tau zoo ntab- taw tes suav nrog 168MHz lub ntsiab zaus thiab 210DMIPS kev ua haujlwm muaj peev xwm, lub cuab yeej ua tiav qhov tsis siv neeg lossis phau ntawv ntsuas cov yam ntxwv ntawm ib zaug -theem thiab peb-theem RCD ua tiav chav nyob, kev tiv thaiv ib nrab ntawm PCs, thiab BA. chaw nres tsheb. Tag nrho cov txheej txheem tau txais 2000Vac tag nrho lub cev kev sib cais architecture, sib cais siab -voltage circuits los ntawm qis-voltage control circuits los xyuas kom meej tus neeg teb xov tooj muaj kev nyab xeeb ntawm cov kab ntau lawm thaum tiv thaiv kev puas tsuaj rau cov cuab yeej los ntawm kev tawm tswv yim yuam kev los ntawm cov qauv kuaj. Nruab nrog lub siab -ceev, siab ntsiag to ntse kub-tswj kiv cua, nws txhawb 24/7 tas mus li ntau lawm kab ua hauj lwm, tuav tag nrho cov kev ntsuam xyuas scenarios los ntawm R & D debugging rau loj ntau lawm Hoobkas tso tawm.

1.Second-Qib Siab Tsis Siv Neeg Test Plan Execution
Txhawb kev sib koom ua ke ntau yam khoom sim suav nrog kev mus ncig tam sim no, lub sijhawm ua haujlwm, thiab tsis yog - lub sijhawm taug kev mus rau hauv cov phiaj xwm sim hauv ib qho kev txiav txim. Cov cuab yeej cia li hloov cov waveforms, voltages, thiab daim ntawv thov txoj haujlwm thoob plaws hauv cov txheej txheem yam tsis muaj kev cuam tshuam tib neeg. Thaum ua tiav, nws cia li tsim ib daim ntawv qhia meej uas muaj cov ntaub ntawv yooj yim, cov ntsiab lus xeem, cov phiaj xwm tsis, cov txheej txheem, thiab ntsuas qhov tseem ceeb, txo qis cov kev xav tau kev txawj ntse thiab qhov ua yuam kev rau cov neeg ua haujlwm ntau lawm.
 

2.Intelligent Interlocking Mechanism rau kev xaiv iav
Thaum xaiv AC waveform ntawm lub vaj huam sib luag tswj, lub cuab yeej cia li kaw polarity-txog iav; hloov mus rau A+0℃waveform cia li qhib lawv. Cov yam ntxwv no tshwm sim los ntawm ntev - lub sij hawm taug qab cov txheeb cais ntawm qhov tseeb ntawm lub Hoobkas ua haujlwm tsis raug - kwv yees li 37% ntawm qhov ntsuas qhov tsis zoo yog tshwm sim los ntawm kev sib xyaw ua ke tsis raug. Kev sib cuam tshuam ntse tshem tawm cov neeg ua yuam kev ntawm qib kho vajtse, txhim kho cov kab ntau lawm ua ntej - kis tawm.
 

3. Cortex M4 Floating -Point Computing Core
Compared with traditional 8-bit/16-bit MCU solutions, the M4 core executes FFT spectrum analysis and true-RMS calculations via its hardware floating-point unit, with waveform synthesis latency below 50μs. This ensures that residual current waveforms remain distortion-free under superimposed DC conditions, maintaining 1% accuracy without degradation even at high leakage current outputs (>1000mA).
 

4.Heavy-Lub luag hauj lwm Connector nrog ruam-Cov ntaub ntawv thaiv kab tsim
Lub vaj huam sib luag tom qab kuaj qauv lub qhov hluav taws xob siv cov lej hnyav - lub luag haujlwm txuas, nrog tus pins 1 ~ 5 sib raug rau L1 / L2 / L3 / N / PE feem. Tsuas yog qhov sib txuam sib txuas tuaj yeem tso tau. Lub cev ruam-cov qauv pov thawj tshem tawm theem- mus rau-theem luv circuits lossis N{11}}wire misconnections tshwm sim los ntawm kev xaim tsis raug. Ntawm -site txheeb cais qhia tau hais tias qhov kev tsim no txo ​​qis cov kab hluav taws xob ntau lawm los ntawm qhov nruab nrab ntawm 4.3 ib hlis mus rau xoom.
 

5.Programmable Contact Detection Type
Hauv PCBA kev xeem hom, cov neeg siv tuaj yeem xaiv ib qho -kev sib cuag lossis arc- kev kuaj xyuas. Tib- hom kev sib cuag siv tau rau cov khoom siv hluav taws xob sib nqus RCDs, thaum arc- hom kev sib cuag nyob rau hauv hluav taws xob RCDs nruab nrog arc chambers. Ob hom siv cov teeb liab sib txawv hauv kev lim dej thiab qhov pib txiav txim siab algorithms, ua kom ntseeg tau tias kev ntes microsecond - theem teeb liab tsis hais txog hom kev mus los.

Scenario 1: Batch Final Inspection ntawm RCD Cov Kab Ntau Lawm
Tom qab luam theej duab barcode thiab ib qho - khawm pib, lub cuab yeej cia li ua tiav qhov kev sim mus ncig tam sim no thiab lub sijhawm ua haujlwm ntawm ib txoj kev npaj ua ntej, nrog kev txiav txim siab tsis siv neeg PASS / FAIL thiab lub Hoobkas tshaj tawm cov khoom tsim- tsis muaj kev cuam tshuam los ntawm phau ntawv, hloov mus rau qhov kev sib tw ntau lawm.

Scenario 2: PCBA Debugging thiab Fault Diagnosis
Txhawb ob qho tib si qis-voltage thiab siab-voltage trip coil drive txoj kev, nyeem PCBA cov lus tawm tswv yim ncaj qha los ntawm qhov chaw nres nkoj teeb liab kom ceev nrooj txheeb xyuas cov teeb meem xws li xoom- sib txawv transformer sib txawv lossis tsav tsis ua haujlwm.

Scenario 3: EV Charging Station Leakage Protection Validation
Txhawb IC-CPD hom thiab superimposed du DC xeem, npog GB/T 18487 thiab IEC 61851 tus qauv. Simulates Hom A/B/F seem tam sim no tsis raug los xyuas kom meej cov logic mus txawv tebchaws thiab lub sijhawm teb ntawm kev tsim-hauv cov qauv kev tiv thaiv tawm.

Scenario 4: Standard Compliance Testing in Third-Party Laboratories
Ua haujlwm ntau-ntau zaus waveforms, DC residual tam sim no, thiab theem- lub kaum sab xis ua kom rov ua tiav tag nrho cov ntawv xeem waveforms ib GB16916, IEC61008, thiab UL2231. Standard MODBUS-RTU raws tu qauv enables yooj yim kev koom ua ke rau hauv automated xeem benches.

Scenario 5: Kev Tshawb Fawb Txog Kev Tshawb Fawb thiab Kev Tshawb Fawb Tsis Ua Haujlwm rau Lub Chaw Haujlwm Zoo
Kev ceev debugging hom tso cai rau qhov hloov pauv hloov pauv ntawm cov nqi seem tam sim no thiab lub sijhawm thov rau ib zaug - kev ua tiav, sai sai rov ua cov tsos mob txhaum cai kom raug txheeb xyuas cov teeb meem khoom lag luam lossis cov txheej txheem tsim khoom.
