Xov Xwm Kev Lag Luam

Kev faib tawm ntawm cov theem hluav taws xob hauv cov kab ke fais fab yog qhov tseem ceeb rau kev ua kom muaj kev xa hluav taws xob zoo, kev faib tawm, thiab kev nyab xeeb. Cov qib hluav taws xob txiav txim siab seb hluav taws xob raug thauj mus los li cas hla cov kab sib txuas, sib npaug rau kev ua tau zoo ntawm kev siv tshuab thiab kev lag luam, thiab hloov kho rau ntau yam kev siv. Tsab xov xwm no tshawb nrhiav cov qauv thiab cov qauv tswj hwm cov kev faib tawm no, nrog rau kev tsom mus rauhluav taws xob siab (HV), ​Qhov hluav taws xob nruab nrab (MV), ​Qhov hluav taws xob qis (LV), thiabLub zog hluav taws xob siab heev (UHV).Kev faib tawm ntawm cov theem hluav taws xob hauv cov kab ke fais fab yog qhov tseem ceeb rau kev ua kom muaj kev xa hluav taws xob zoo, kev faib tawm, thiab kev nyab xeeb.

Ua ib lub tuam txhab tsim khoom uas tshwj xeeb hauv cov transformers nruab nrab thiab siab voltage, JZP Power Transformer zoo siab tshaj tawm peb txoj kev koom tes hauv ENLIT Europe 2025—qhov kev tshwm sim tseem ceeb tshaj plaws hauv teb chaws rau kev tsim kho tshiab ntawm lub zog. Txij lub Kaum Ib Hlis 18–20, 2025, peb yuav nthuav tawm peb cov kev daws teeb meem tshiab ntawm Bilbao Exhibition Center (48100 Bilbao, Bizkaia, Spain). Tuaj saib peb ntawm Booth 3.F122 kom paub seb peb tab tom tsim lub neej yav tom ntej ntawm kev xa hluav taws xob thiab kev faib tawm li cas.

Nyob rau hauv lub ntiaj teb kev hloov pauv ntawm cov khoom siv hluav taws xob, JZP sawv cev rau lub zog ua thawj coj tshwj xeeb hauv cov hloov pauv hluav taws xob nruab nrab thiab siab - lub hauv paus ntawm kev xa hluav taws xob zoo, kev faib tawm, thiab kev siv. Nrog ntau xyoo ntawm kev txawj ntse, kev siv tshuab tshiab, thiab kev cog lus tsis hloov pauv rau qhov zoo, peb txhawb nqa cov lag luam, cov khoom siv hluav taws xob, thiab cov haujlwm thoob ntiaj teb kom ua tiav cov kev daws teeb meem hluav taws xob txhim khu kev qha, ruaj khov, thiab pheej yig.

Switchgear ua haujlwm ua tus txha nqaj qaum ntawm nruab nrab thiab siab voltage (MV / HV) fais fab systems, ua peb lub luag haujlwm tseem ceeb rau transformers:

• ​Kev Faib Fais FabKev xa hluav taws xob los ntawm transformers mus rau cov khoom thauj los ntawm cov khoom noj, cov busbars, thiab cov khoom siv tiv thaiv.
• ​Kev Tiv Thaiv Kev Txhaum Cai: Cuam tshuam cov teeb meem tam sim no hauv milliseconds (piv txwv li, 31.5kA–40kA luv-circuit breaking peev xwm) kom tiv thaiv cov khoom siv puas tsuaj.
• ​Kev Cais Tawm Kev Nyab Xeeb: Xyuas kom muaj kev saib xyuas zoo los ntawm kev sib txuas lus thiab cov txheej txheem av.

Piv txwv li, ib lub tshuab 12kV xav tau qhov tsawg kawg nkaus ntawm theem mus rau hauv av ntawm 125mm (cua-insulated) lossis 40mm (gas-insulated) kom tiv thaiv arcing.

​Kev Tshawb Fawb Txog M&H Voltage Power Electronic Transformer Hom, Kev Teeb tsa Qauv, thiab Cov Txheej Txheem Tseem Ceeb

Cov ntaub ntawv qhia txog Neutral Point Clamped (NPC) multilevel topology. Ntxiv rau qhov diode-clamped NPC topology, NPC topology kuj suav nrog flying capacitor hom thiab hybrid clamped hom, thiab lwm yam. Txawm li cas los xij, vim muaj cov capacitor loj, NPC topology feem ntau tseem siv cov khoom siv passive lossis active switching rau clamping. Piv txwv li, siv diode-clamped multilevel topology, hauv peb-theem rectifier theem topology, txhua ceg theem muaj cov cascaded switching transistors thiab clamping diodes, txuas nrog parallel rau ib lub tsheb npav DC siab-voltage. Cov ntaub ntawv tau hais txog ib-theem PET topology nrog ib theem rectifier siv plaub-theem diode-clamped circuit. Ib lub tsheb npav DC siab-voltage ua raws li input-series-output-parallel DABs, raws li qhia. Cov topology no tuaj yeem nthuav dav mus rau hauv peb-theem qauv, thiab tus lej ntawm cov theem voltage tuaj yeem hloov pauv raws li cov khoom siv voltage thiab qib siab-voltage sab voltage. Ib yam li MMC topology, NPC topology kuj tseem siv tau rau theem cais tawm, txuas lub tsheb npav DC siab-voltage rau lub transformer cais tawm, raws li qhia. Cov ntaub ntawv tau siv lub tshuab hloov pauv NPC peb-theem diode-clamped rau sab high-voltage ntawm LLC resonant converter, txheeb xyuas nws ntawm 166kW / 2kV ~ 400V prototype. Cov ntaub ntawv tau siv lub voj voog NPC peb-theem diode-clamped rau peb-theem DAB, ua tiav cov yam ntxwv DAB voltage thiab tam sim no zoo tagnrho.

Cov qauv PET sib txawv ntau heev. Raws li tus lej ntawm cov theem hloov pauv zog, lawv tuaj yeem faib ua ib theem, ob theem, thiab peb theem [7]. Cov qauv ob theem suav nrog cov uas muaj cov tsheb npav DC siab thiab qis, raws li pom hauv Daim Duab 1.

Nrog rau kev pom zoo ntawm lub tswv yim ntawm lub zog hauv internet thiab kev siv dav dav ntawm cov thev naus laus zis ntsig txog smart grid, qhov feem pua ​​ntawm cov khoom siv hluav taws xob rov ua dua tshiab xws li cua thiab photovoltaic fais fab hauv lub zog uas twb muaj lawm yuav nce ntxiv ntau heev. Qhov no qhia tau hais tias cov fais fab yav tom ntej yuav ntse dua thiab yoog tau yooj yim dua. Hauv lub zog hauv internet, thaum qhov feem pua ​​ntawm cov neeg siv faib tawm thiab cov peev txheej hluav taws xob nce siab, kev xa hluav taws xob xav tau cov peev xwm tswj tau zoo heev. Hauv cov tes hauj lwm faib tawm ntse, lub grid yuav tsum tswj hwm cov khoom siv hluav taws xob ruaj khov thiab zoo thaum sib koom ua ke ntau ntawm cov khoom siv hluav taws xob rov ua dua tshiab thiab saib xyuas / tswj hwm cov xwm txheej ua haujlwm ntawm lub grid. Cov kev cai no tso cov kev xav tau nruj rau kev txawj ntse ntawm cov khoom siv hluav taws xob grid, thaum cov hloov pauv zaus fais fab ib txwm muaj kev txwv kev ua haujlwm.

Lub tshuab hluav taws xob high-voltage yog ib lub cuab yeej hluav taws xob uas tau tsim los hloov lub zog hluav taws xob ntawm cov theem voltage, feem ntau ua haujlwm hauv qhov ntau ntawm110 kV txog 500 kVCov transformers no yog qhov tseem ceeb hauv cov kab ke xa hluav taws xob, txo qhov kev poob hluav taws xob thaum lub sijhawm xa hluav taws xob mus deb thaum ua kom muaj kev xa hluav taws xob mus rau tsev neeg, cov lag luam, thiab cov lag luam kom muaj kev nyab xeeb. Piv txwv li, cov chaw tsim hluav taws xob tsim hluav taws xob ntawm cov hluav taws xob siab, thiab cov transformers kho qhov hluav taws xob no - txawm tias nce nws rau kev xa hluav taws xob lossis txo nws rau cov neeg siv kawg - kom ua kom zoo dua qub thiab kev nyab xeeb.
