Semugadziri anotungamira mukugadzira ma transformer emagetsi epakati nepamagetsi akakwira, JZP Power Transformer inofara kuzivisa kuti tave kutora chikamu mu ENLIT Europe 2025—chiitiko chikuru chekuvandudza simba mukondinendi. Kubva muna Mbudzi 18–20, 2025, ticharatidza mhinduro dzedu dzemazuva ano kuBilbao Exhibition Centre (48100 Bilbao, Bizkaia, Spain). Tishanyirei paBooth 3.F122 kuti muone kuti tiri kuumba sei ramangwana rekutumira nekugovera simba.

Mumamiriro ezvinhu anochinja-chinja esimba repasi rose, JZP inomira sesimba guru rinoona nezvema transformer emagetsi ari pakati nepakati nepamusoro—musimboti wekutumira, kugovera, uye kushandisa simba zvinobudirira. Nemakumi emakore ehunyanzvi, tekinoroji yemazuva ano, uye kuzvipira kusingazununguki kune mhando, tinosimudzira maindasitiri, makambani emagetsi, nemapurojekiti pasi rese kuti vawane mhinduro dzesimba dzakavimbika, dzinogara kwenguva refu, uye dzinodhura zvishoma.

Switchgear inoshanda semusana wemagetsi epakati nepakakwirira (MV/HV), ichiita mabasa matatu akakosha kune matransformer:

• ​Kugoverwa Kwesimba: Inofambisa magetsi kubva kumatransformer kuenda kumitoro kuburikidza nemafeeder, mabhazi, uye zvishandiso zvekudzivirira.
• ​Dziviriro Yemhosva: Inovhiringidza ma currents mukati mema milliseconds (semuenzaniso, 31.5kA–40kA short-circuit break capacity) kudzivirira kukuvara kwemidziyo.
• ​Kuzviparadzanisa Nevamwe Vakachengeteka: Inoita kuti pave nekugadziriswa kwakachengeteka kuburikidza nekubatanidza michina uye nzira dzepasi.

Semuenzaniso, sisitimu ye12kV inoda nzvimbo shoma kubva pasi kuenda pasi ye125mm (inodzivirirwa nemhepo) kana 40mm (inodzivirirwa negesi) kudzivirira kutenderera kwemugero.

​Kuongororwa Kwakadzama kweM&H Voltage Power Electronic Transformer Types, Structural Configurations, uye Key Parameters

Nzvimbo ine Neutral Point Clamped (NPC) ine mazinga akawanda inoratidzwa. Kunze kwenzvimbo ine diode-clamped NPC, nzvimbo dzine NPC dzinosanganisirawo mhando ye flying capacitor uye mhando ine hybrid clamped, pakati pezvimwe. Zvisinei, nekuda kwehuwandu hukuru hwe capacitor, nzvimbo dzine NPC dzichiri kushandisa zvakanyanya passive kana active switching devices passive kana active switching devices. Tichitora nzvimbo ine diode-clamped multilevel semuenzaniso, mune three-phase rectifier stage topology, phase leg yega yega ine cascaded switching transistors uye clamping diodes, dzakabatana zvakafanana ne single high-voltage DC bus. Mabhuku akakurudzira single-phase PET topology ine rectifier stage ichishandisa four-level diode-clamped circuit. Single high-voltage DC bus inoteverwa ne input-series-output-parallel DABs, sezvakaratidzwa. Iyi nzvimbo inogona kuwedzerwa kuita three-phase structure, uye huwandu hwe voltage levels hunogona kuchinjwa zvichienderana ne device standing voltage levels uye high-voltage side voltage level. Kufanana neMMC topology, NPC topology inogonawo kushandiswa padanho rekupatsanura, ichibatanidza bhazi reDC rine voltage yakakwira netransformer yekupatsanura, sezvakaratidzwa. Mabhuku akashandisa converter yeNPC ine diode-clamped yemazinga matatu kudivi revoltage reLLC resonant converter, vachiisimbisa paprototype ye166kW/2kV~400V. Mabhuku akashandisa circuit yeNPC ine diode-clamped yemazinga matatu kuDAB ine phase nhatu, zvichiita kuti DAB voltage yakanakira uye hunhu hwemazuva ano huve hwakakodzera.

Matoporiji ePET anosiyana zvakanyanya. Zvichienderana nehuwandu hwematanho ekushandura simba, anogona kuiswa muzvikamu zveimwe-nhanho, zviviri-nhanho, uye zvitatu-nhanho [7]. Maumbirwo ezvikamu zviviri anosanganisira ayo ane mabhazi eDC ane voltage yakakwira uye yakaderera, sezvakaratidzwa muMufananidzo 1.

Nekukurudzirwa kwepfungwa yeinternet yesimba uye kushandiswa kwakapararira kwetekinoroji ine chekuita negrid yakangwara, huwandu hwesimba rinogona kudzokororwa senge simba remhepo nemagetsi aripo muhurongwa hwesimba huripo huchawedzera zvakanyanya. Izvi zvinoratidza kuti magrid emagetsi emangwana achava akangwara uye anochinjika. Muinternet yesimba, sezvo huwandu hwevashandisi vakagoverwa uye zviwanikwa zvesimba zvichikwira, kutapurirana kwemagetsi kunoda kugona kudzorwa zvakanyanya. Munetwork dzemagetsi dzakangwara, grid inofanira kuchengetedza simba rakasimba uye remhando yepamusoro uku ichibatanidza huwandu hwakawanda hwesimba rinogona kudzokororwa rakagoverwa uye mamiriro ekutarisa/kutarisira mashandiro egrid. Izvi zvinodiwa zvinoisa zvinodiwa zvakanyanya pahungwaru hwemidziyo yemagetsi, nepo ma transformer emagetsi echinyakare anotarisana nemiganho yekushanda.

Muchina wemagetsi une simba guru (high-voltage transformer) mudziyo wemagetsi wakagadzirwa kushandura simba remagetsi pakati pemazinga emagetsi, unowanzo shanda mukati mehuwandu hwemagetsi.110 kV kusvika 500 kVMatransformer aya akakosha muhurongwa hwekutumira magetsi, anoderedza kurasikirwa kwesimba panguva yekutumira magetsi kure ukuwo achivimbisa kuti magetsi anosvika kumhuri, mabhizinesi, nemaindasitiri zvakachengeteka. Semuenzaniso, mafekitori emagetsi anogadzira magetsi ane voltage yakakwira, uye matransformer anogadzirisa voltage iyi—kungave kuiwedzera kuti iendeswe kana kuideredza kuti ishandiswe nevashandisi vekupedzisira—kuti iwedzere kushanda zvakanaka uye kuchengetedzeka.
