Monga wopanga wotsogola wodziwa bwino ntchito zosinthira magetsi apakati ndi okwera, JZP Power Transformer ikusangalala kulengeza kutenga nawo gawo kwathu mu ENLIT Europe 2025—chochitika chachikulu kwambiri cha kupanga mphamvu mu kontinenti. Kuyambira pa Novembala 18–20, 2025, tidzawonetsa njira zathu zamakono ku Bilbao Exhibition Centre (48100 Bilbao, Bizkaia, Spain). Tiyendereni ku Booth 3.F122 kuti mudziwe momwe tikupangira tsogolo la kutumiza ndi kugawa magetsi.

Mu gawo losinthasintha la zomangamanga zamphamvu padziko lonse lapansi, JZP ndi gulu lotsogola lomwe limayang'anira ma transformer apakati ndi okwera kwambiri—msana wa kutumiza mphamvu moyenera, kugawa, ndi kugwiritsa ntchito. Ndi zaka zambiri zaukadaulo, ukadaulo wapamwamba, komanso kudzipereka kosalekeza ku khalidwe labwino, timapatsa mphamvu mafakitale, mautumiki, ndi mapulojekiti padziko lonse lapansi kuti tikwaniritse mayankho amagetsi odalirika, okhazikika, komanso otsika mtengo.

Switchgear imagwira ntchito ngati maziko a makina amphamvu apakati ndi okwera kwambiri (MV/HV), ikugwira ntchito zitatu zofunika kwambiri pa ma transformer:

• ​Kugawa Mphamvu: Imayendetsa magetsi kuchokera ku ma transformer kupita ku katundu kudzera m'ma feeder, mabasi, ndi zipangizo zotetezera.
• ​Chitetezo cha Zolakwa: Imalepheretsa mafunde mkati mwa ma millisecond (monga, mphamvu ya kusweka kwa mafunde afupiafupi a 31.5kA–40kA) kuti iteteze kuwonongeka kwa zida.
• ​Kudzipatula pa Chitetezo: Imaonetsetsa kuti ikusamalidwa bwino pogwiritsa ntchito makina olumikizirana ndi njira zomangira pansi.

Mwachitsanzo, makina a 12kV amafunika malo ocheperako a 125mm (otetezedwa ndi mpweya) kapena 40mm (otetezedwa ndi mpweya) kuti asagwere pansi.

​Kusanthula Kwatsatanetsatane kwa Mitundu ya M&H Voltage Power Electronic Transformer, Makonzedwe a Kapangidwe, ndi Magawo Ofunika

Topology ya Neutral Point Clamped (NPC) multilevel ikuwonetsedwa. Kupatula topology ya NPC yokhala ndi diode-clamped, ma topology a NPC akuphatikizaponso flying capacitor type ndi hybrid clamped type, pakati pa ena. Komabe, chifukwa cha kuchuluka kwa capacitor, ma topology a NPC amagwiritsabe ntchito zida zosinthira zosagwira ntchito kapena zogwira ntchito poyimitsa. Potengera topology ya diode-clamped multilevel monga chitsanzo, mu topology ya magawo atatu yoyimitsa, gawo lililonse limapangidwa ndi ma transistors osinthira ndi ma clamping diode, olumikizidwa motsatira basi imodzi ya DC yamagetsi amphamvu. Mabuku adapereka topology ya gawo limodzi la PET yokhala ndi gawo loyimitsa pogwiritsa ntchito dera la magawo anayi loyimitsa diode. Basi imodzi yamagetsi amphamvu ya DC imatsatiridwa ndi ma DAB olowera-mndandanda-wotulutsa-wofanana, monga momwe zasonyezedwera. Topology iyi ikhoza kukulitsidwa kukhala kapangidwe ka magawo atatu, ndipo kuchuluka kwa milingo yamagetsi kumatha kusinthidwa kutengera milingo yamagetsi yopirira chipangizo komanso mulingo wamagetsi amphamvu. Monga topology ya MMC, topology ya NPC ingagwiritsidwenso ntchito pa gawo lodzipatula, kulumikiza basi ya DC yamagetsi amphamvu kwambiri ku transformer yodzipatula, monga momwe zasonyezedwera. Mabuku adagwiritsa ntchito chosinthira cha NPC chokhala ndi ma diode atatu mbali ya voltage yapamwamba ya chosinthira cha resonant cha LLC, ndikuchitsimikizira pa prototype ya 166kW/2kV ~ 400V. Mabuku adagwiritsa ntchito dera la NPC lokhala ndi ma diode atatu ku DAB ya magawo atatu, zomwe zidakwaniritsa mphamvu ya DAB komanso mawonekedwe ake amagetsi.

Ma PET topologies amasiyana kwambiri. Kutengera kuchuluka kwa magawo osinthira mphamvu, amatha kugawidwa m'magulu a magawo amodzi, awiri, ndi atatu [7]. Kapangidwe ka magawo awiri kakuphatikizapo omwe ali ndi mabasi a DC amphamvu komanso otsika, monga momwe zasonyezedwera pa Chithunzi 1.

Ndi lingaliro la lingaliro la intaneti yamagetsi komanso kugwiritsa ntchito kwambiri ukadaulo wanzeru wokhudzana ndi gridi, kuchuluka kwa magwero amagetsi obwezerezedwanso monga mphamvu ya mphepo ndi photovoltaic mu dongosolo lamagetsi lomwe lilipo lidzawonjezeka kwambiri. Izi zikusonyeza kuti ma gridi amagetsi amtsogolo adzakhala anzeru komanso osinthasintha. Mu intaneti yamagetsi, pamene kuchuluka kwa ogwiritsa ntchito ogawidwa ndi zinthu zamagetsi kukukwera, kutumiza magetsi kumafuna mphamvu zowongolera kwambiri. Mu ma netiweki ogawa magetsi anzeru, gridi iyenera kukhala ndi magetsi okhazikika komanso apamwamba kwambiri pomwe ikuphatikiza magwero ambiri amagetsi obwezerezedwanso ogawidwa komanso kuyang'anira/kuyang'anira magwiridwe antchito a gridi. Zofunikira izi zimayika zofunikira kwambiri pa luntha la zida zamagetsi, pomwe ma transformer amagetsi achikhalidwe amakumana ndi zoletsa zogwirira ntchito.

Chosinthira chamagetsi champhamvu ndi chipangizo chamagetsi chomwe chimapangidwa kuti chisinthe mphamvu zamagetsi pakati pa milingo yamagetsi, nthawi zambiri chimagwira ntchito mkati mwa ​110 kV mpaka 500 kVMa transformer awa ndi ofunikira kwambiri mu makina otumizira magetsi, amachepetsa kutayika kwa mphamvu panthawi yotumizira magetsi mtunda wautali komanso kuonetsetsa kuti magetsi afika bwino m'nyumba, m'mabizinesi, ndi m'mafakitale. Mwachitsanzo, mafakitale opanga magetsi amapanga magetsi pamagetsi okwera kwambiri, ndipo ma transformer amasintha magetsi awa—kaya kuwawonjezera kuti apereke magetsi kapena kuwachepetsa kuti agwiritsidwe ntchito ndi ogwiritsa ntchito—kuti awonjezere magwiridwe antchito ndi chitetezo.

JZP Transformer ndi mtsogoleri padziko lonse lapansi pantchito yotumikira gawo la mphamvu zongowonjezwdwa padziko lonse lapansi. Ndi mbiri yotsimikizika, tapereka ma transformer zikwizikwi a mapulojekiti osungira mphamvu ndi ma photovoltaic ku North America, Europe, ndi Australia. Zogulitsa zathu sizimakwaniritsa miyezo yokhwima monga IEEE, ANSI, CSA, AN, IEC, ndi BS, komanso zili ndi ziphaso kuphatikizapo UL, cUL, CSA, CE, SGS, ndi zina, zothandizidwa ndi malipoti athunthu a mayeso.
