Kuyesa Mphamvu ya Hydrogen Yodalirika Kwambiri ya "Sentinel" — Chida Chowunikira Voltage cha N1200 Series

Pamene kapangidwe ka mphamvu padziko lonse kakusintha kukhala njira zothetsera mpweya wochepa komanso mphamvu zoyera, mphamvu ya haidrojeni yakhala ngati chonyamulira champhamvu chodalirika kwambiri. Unyolo wake wa mafakitale ukukwera mofulumira pa chitukuko cha ukadaulo komanso malonda. Pakati pa izi, maselo amafuta ndi ma electrolysis amadzi machitidwe opangira haidrojeni (ma electrolyzers) akuyimira mizati iwiri yayikulu ya "kupanga mphamvu" yochokera ku haidrojeni ndi "kupanga haidrojeni."

Mu ntchito zonse ziwiri, stack ndiye gawo lofunika kwambiri. Kugwira ntchito kwake, nthawi yogwirira ntchito, ndi chitetezo chake zimatsimikiza mwachindunji kupambana kapena kulephera kwa dongosolo lonse. Kuyang'anira molondola, mwachangu, komanso modalirika mphamvu ya ma cell mazana kapena masauzande ambiri mkati mwa stack ndi chinthu chofunikira kwambiri panthawi yonse ya kafukufuku ndi chitukuko, kupanga, kuyesa, ndi kugwiritsa ntchito ndi kukonza.

Kuyesa Zopinga mu Makampani a Hydrogen: Mavuto Aukadaulo Okhudza Kuwunika Voltage

Ma cell amafuta ndi ma electrolyzer onse amapangidwa polumikiza ma cell ambiri ku masauzande ambiri kuti akwaniritse mphamvu zambiri komanso mphamvu zambiri. Ngakhale kuti kapangidwe kameneka kamalola kusonkhanitsa mphamvu, kamayambitsa zovuta zomwe sizinachitikepo kuti pakhale kuyeza mphamvu molondola.

Mafuta a haidrojeni

Choyezera madzi

Pa nthawi yogwira ntchito kwa maselo amafuta, mphamvu ya selo lililonse—nthawi zambiri pakati pa 0.5 V ndi 1.0 V—ndi chizindikiro chodziwikiratu komanso chodziwikiratu cha thanzi la selo. Kusakhazikika kwa mphamvu yamagetsi monga kusakhala ndi mphamvu yamagetsi, kutembenuka kwa polarity, kapena kusasinthasintha kumawonetsa mwachindunji kuwonongeka kwa magwiridwe antchito, kulephera kwa malo, kapena ngakhale zolakwika zoopsa. Chifukwa chake, kuwunika mphamvu yamagetsi nthawi yeniyeni, yogwirizana, komanso yolondola kwambiri ya selo lililonse ndikofunikira.

Kuchepetsa Mphamvu ya Voltage ya Common-Mode (CMV)

Poyesa selo yomwe ili pafupi ndi pamwamba pa mulu, mphamvu yake yaying'ono yosiyana (pafupifupi 0.8 V) imayikidwa pa mphamvu yapamwamba kwambiri ya common-mode poyerekeza ndi nthaka ya makina oyesera. Mphamvu yochulukirapo ya common-mode ingawononge zida zoyezera ndikuwononga kwambiri kulondola kwa muyeso, zomwe zimapangitsa kuti kuletsa kwa CMV kukhala vuto lalikulu laukadaulo.

Malo Ovuta a Magetsi a Magetsi

Mabenchi oyesera mphamvu ya haidrojeni nthawi zambiri amakhala ndi zida zamagetsi zamagetsi zamphamvu kwambiri, magetsi, ndi ma inverter. Zipangizozi zimapanga kusokoneza kwamphamvu kwa electromagnetic (EMI) panthawi yogwira ntchito. Malo ovuta otere a electromagnetic amatha kusokoneza kwambiri kukhazikika kwa sampling ya voltage, zomwe zimapangitsa kuti deta yoyesedwa isinthe kwambiri.

Kupeza Magalimoto Othamanga Kwambiri Pamodzi Pama Channel Aakulu

Njira zoyezera zachikhalidwe zosanthula kapena zoyesera pogwiritsa ntchito mavoti zimasintha njira motsatizana, zomwe zimayambitsa kuchedwa kwa nthawi. Pamene njira mazana ambiri zaskenidwa, kusiyana kwa nthawi pakati pa njira yoyamba ndi yomaliza kumatha kufika makumi kapena mazana a ma millisecond. Pansi pa mikhalidwe yosinthasintha mwachangu, deta yotereyi imakhala yosagwira ntchito, kulephera kuwonetsa momwe mkati mwa stack imakhalira nthawi yomweyo ndikupangitsa kuti isayenerere kuzindikira zolakwika kapena kupanga chitsanzo molondola.

Yankho Lowunikira Voltage Yapamwamba ya NGI

Pogwiritsa ntchito kafukufuku wa nthawi yayitali komanso luso lothandiza mumakampani opanga mphamvu za hydrogen, NGI yapanga chida chowunikira mphamvu zamagetsi cha N1200 Series cha njira zambiri. Kudzera mu kapangidwe ka modular isolation, N1200 imathetsa vuto la mphamvu zamagetsi zamagetsi zamagetsi zamagetsi. Pogwiritsa ntchito ukadaulo wowongolera womwe umachokera ku FPGA, imapeza chitukuko chachikulu pakupeza deta yothamanga kwambiri. Kuphatikiza apo, kapangidwe kodalirika ka mafakitale kamaonetsetsa kuti ntchito yodalirika ikugwira ntchito m'malo ovuta oyesera.

Pamodzi, matekinoloje atatu ofunikira awa amakhazikitsa N1200 Series ngati yankho lofunikira kwambiri laukadaulo poyesa mphamvu ya hydrogen, lomwe limagwiritsidwa ntchito kwambiri pakuwunika magetsi amagetsi ndi ma cell amafuta.

Kulondola Kwambiri ndi Chitetezo Champhamvu cha Voltage cha Common-Mode

Mndandanda wa N1200 umagwiritsa ntchito njira yopezera zinthu modular grouped ndi multi-level isolation architecture, kugawa magetsi mu stack ya high-voltage kukhala "magulu a cell" angapo otsika mphamvu. Gulu lililonse limayang'aniridwa ndi front-end acquisition module yodziyimira payokha, yomwe imathetsa mavuto a common-mode voltage m'ma volts mazana ambiri mpaka zikwizikwi.

Chiŵerengero chapamwamba kwambiri cha common-mode rejection ratio (CMRR) ndicho chofunikira kwambiri pakuyesa molondola kwambiri, kuletsa bwino phokoso ndi kusinthasintha komwe kumachitika chifukwa cha mphamvu ya common-mode ndikuwonetsetsa kuti muyeso ndi wolondola.

Kupirira EMI Yovuta Kwambiri Kuti Mukhale Wodalirika Kwambiri

Kusokoneza kwa maginito komwe kumachitika ndi zingwe zamagetsi zamagetsi ambiri nthawi zambiri kumakhala pamwamba pa mizere yazizindikiro mu mawonekedwe a phokoso la common-mode, zomwe zimapangitsa kuti deta yamagetsi isinthe kwambiri.

N1200 Series imagwiritsa ntchito mayunitsi oyesera amagetsi omwe ali ndi ma modular electrically isolated front-end sampling units ophatikizidwa ndi differential signal processing (ma amplifier a zida), omwe amapereka chitetezo chapadera ku EMI ndi phokoso la common-mode pomwe akuwonjezera voliyumu yeniyeni yosiyana - yomwe ndi voliyumu ya selo iliyonse.

Kupeza Mayendedwe Othamanga Kwambiri a Ma Channel Aakulu

N1200 Series imasiya njira zachikhalidwe zosinthira ma multiplexed kapena zomangamanga za ADC polling. M'malo mwake, imagwiritsa ntchito FPGA yayikulu ngati chowongolera chachikulu. Deta ya digito yomwe imasinthidwa ndi mayunitsi opeza ma front-end imatumizidwa payokha komanso mofanana ndi FPGA kudzera mu zopatula zapadera za digito.

Kapangidwe kameneka kamalola kuti zitsanzo zenizeni zofanana zipezeke ndikusinthidwa mkati mwa 10 ms. Chifukwa chake, mainjiniya amatha kujambula momwe magetsi alili m'maselo onse nthawi imodzi, zomwe zimapangitsa kuti pakhale maziko olimba a deta yowunikira magwiridwe antchito komanso kuwunika kolondola kwa kusinthasintha.

Kuyang'ana Patsogolo

Pamene ukadaulo wa mphamvu ya haidrojeni ukupitirirabe kusintha, zofunikira pakuwunika mphamvu yamagetsi zidzakhala zovuta kwambiri. Mavuto amtsogolo akuphatikizapo ma voltage stacks apamwamba (>1500 V), mayankho ofulumira (kuchuluka kwa zitsanzo), komanso kusakanikirana kwa deta mozama ndi magawo ena akuthupi monga kutentha, kupanikizika, ndi kulephera kwa magetsi.

Ndi zaka zambiri zaukadaulo woyesa mafakitale komanso zida zambiri zoyesera ma cell amafuta, NGI ili pamalo abwino popereka zinthu zosiyanasiyana zoyesera komanso mayankho aukadaulo oyesera mphamvu ya hydrogen, nthawi zonse kupereka maziko olimba komanso odalirika a data kuti apititse patsogolo makampani opanga mphamvu ya hydrogen.
