Njengomvelisi ophambili ogxile kwiitransformer ze-voltage ephakathi nephezulu, i-JZP Power Transformer ivuya kakhulu ukuvakalisa ukuba sithatha inxaxheba kwi-ENLIT Europe 2025—umsitho ophambili kwilizwekazi wezinto ezintsha zamandla. Ukususela nge-18-20 kaNovemba 2025, siza kubonisa izisombululo zethu ezisemgangathweni kwiZiko leMiboniso laseBilbao (48100 Bilbao, Bizkaia, eSpain). Sityelele eBooth 3.F122 ukuze ufumane indlela esibumba ngayo ikamva lokudluliselwa kwamandla kunye nokusasazwa kwawo.

Kwindawo eguquguqukayo yeziseko zamandla zehlabathi, i-JZP imele njengeqela eliphambili eligxile kwi-transformers ze-voltage ephakathi nephezulu—umqolo wokudluliselwa kwamandla, ukusasazwa, kunye nokusetyenziswa kwawo ngokufanelekileyo. Ngolwazi lwamashumi eminyaka, ubuchwepheshe obuphambili, kunye nokuzibophelela okungagungqiyo kumgangatho, sixhobisa amashishini, iinkonzo, kunye neeprojekthi kwihlabathi liphela ukuze sifezekise izisombululo zamandla ezinokuthenjwa, ezizinzileyo, nezingabizi kakhulu.

Iswitshi sisebenza njengomqolo weenkqubo zamandla ze-voltage ephakathi nephezulu (MV/HV), senza imisebenzi emithathu ebalulekileyo kwiitransformer:

• ​Ukusasazwa koMbane: Ihambisa umbane ukusuka kwiitransformer ukuya kwimithwalo ngezixhobo zokuphakela, iibhasi, kunye nezixhobo zokukhusela.
• ​Ukukhuselwa kweMpazamo: Iphazamisa ukusebenza kwe-currents ngaphakathi kwee-milliseconds (umz., amandla okuphuka kwe-short-circuit engama-31.5kA–40kA) ukuthintela umonakalo kwizixhobo.
• ​Ukuzahlula kuKhuseleko: Iqinisekisa ukugcinwa okukhuselekileyo ngokusebenzisa iindlela zokudibanisa oomatshini kunye neendlela zokumisa umhlaba.

Umzekelo, inkqubo ye-12kV ifuna ubuncinci bokususwa kwe-phase-to-ground kwe-125mm (i-air-insulated) okanye i-40mm (i-gas-insulated) ukuthintela ukungqubana

​Uhlalutyo oluneenkcukacha lweeM&H Voltage Power Electronic Transformer Types, Structure Configurations, kunye neeKey Parameters

I-topology ye-Neutral Point Clamped (NPC) multilevel ibonisiwe. Ngaphandle kwe-topology ye-NPC ene-diode-clamped, ii-topology ze-NPC ziquka uhlobo lwe-flying capacitor kunye nohlobo lwe-hybrid clamped, phakathi kwezinye. Nangona kunjalo, ngenxa yomthamo omkhulu we-capacitor, ii-topology ze-NPC zisasebenzisa kakhulu izixhobo zokutshintsha ezingasebenziyo okanye ezisebenzayo zokucinezela. Ukuthatha i-topology ye-diode-clamped multilevel njengomzekelo, kwi-topology yesigaba se-rectifier esinezigaba ezintathu, umlenze ngamnye wesigaba uqulathe ii-transistors zokutshintsha ezicascaded kunye nee-diode zokubopha, eziqhagamshelwe ngokuhambelana nebhasi enye ye-DC ene-voltage ephezulu. Uncwadi lucebise i-topology ye-PET yesigaba esinye enesigaba sokulungisa kusetyenziswa isekethe ene-diode-clamped enezigaba ezine. Ibhasi enye ye-DC ene-voltage ephezulu ilandelwa yi-input-series-output-parallel DABs, njengoko kubonisiwe. Le topology inokwandiswa ibe yisakhiwo sesigaba sesithathu, kwaye inani lamanqanaba e-voltage linokutshintshwa ngokusekelwe kumanqanaba e-voltage amelana nesixhobo kunye nenqanaba le-voltage esecaleni ye-voltage ephezulu. Njenge-topology ye-MMC, i-topology ye-NPC ingasetyenziswa nakwisigaba sokuzihlukanisa, idibanisa ibhasi ye-DC ene-voltage ephezulu kwi-transformer yokuzihlukanisa, njengoko kubonisiwe. Uncwadi lusebenzise i-converter ye-NPC ene-diode-clamped yamanqanaba amathathu kwicala le-voltage ephezulu ye-converter ye-LLC resonant, iqinisekisa kwi-prototype ye-166kW/2kV ~ 400V. Uncwadi lusebenzise isekethe ye-NPC ene-diode-clamped yamanqanaba amathathu kwi-DAB yezigaba ezintathu, ifezekisa i-voltage ye-DAB efanelekileyo kunye neempawu zangoku.

Ii-topologies ze-PET zahlukile kakhulu. Ngokusekelwe kwinani lamanqanaba okuguqulwa kwamandla, anokwahlulwahlulwa abe ziintlobo zesigaba esinye, izigaba ezibini, kunye nezigaba ezintathu [7]. Izakhiwo zezigaba ezibini ziquka ezo zinebhasi ze-DC ezine-voltage ephezulu kunye ne-voltage ephantsi, njengoko kubonisiwe kuMfanekiso 1.

Ngesiphakamiso sengcamango ye-intanethi yamandla kunye nokusetyenziswa ngokubanzi kwezobuchwepheshe ezinxulumene negridi ekrelekrele, umlinganiselo wemithombo yamandla avuselelekayo njengamandla omoya kunye ne-photovoltaic kwinkqubo yamandla ekhoyo uya kwanda kakhulu. Oku kubonisa ukuba iigridi zamandla ezizayo ziya kuba nobuchule ngakumbi kwaye ziguquguquke. Kwi-intanethi yamandla, njengoko umlinganiselo wabasebenzisi abasasaziweyo kunye nezixhobo zamandla unyuka, ukuhanjiswa kombane kufuna amandla alawulekayo kakhulu. Kwiinethiwekhi zokusasazwa ezikrelekrele, igridi kufuneka igcine umbane ozinzileyo nosemgangathweni ophezulu ngelixa idibanisa inani elikhulu lemithombo yamandla avuselelekayo asasaziweyo kunye nokubeka esweni/ukulawula iimeko zokusebenza kwegridi. Ezi mfuno zibeka iimfuno ezingqongqo kubuchule bezixhobo zegridi yamandla, ngelixa ii-transformers zesiqhelo zamandla zijongene nemida yokusebenza.

I-transformer ye-high-voltage sisixhobo sombane esenzelwe ukuguqula amandla ombane phakathi kwamanqanaba ombane, esihlala sisebenza ngaphakathi koluhlu110 kV ukuya kwi-500 kVEzi transformers zibalulekile kwiinkqubo zokuhambisa umbane, zinciphisa ukulahleka kwamandla ngexesha lokuhambisa umgama omde ngelixa ziqinisekisa ukuhanjiswa kombane ngokukhuselekileyo kumakhaya, kumashishini nakwimizi-mveliso. Umzekelo, izityalo zamandla zivelisa umbane ngee-voltage eziphezulu, kwaye ii-transformers zilungisa le voltage—nokuba ziyayinyusa ukuze idluliselwe okanye ziyinciphise ukuze isetyenziswe ngabasebenzisi bokugqibela—ukuphucula ukusebenza kakuhle nokhuseleko.
