Amakuru y'inganda

Gushyira mu byiciro urugero rw'amashanyarazi mu buryo bw'ingufu ni ingenzi mu gutuma ingufu zikwirakwizwa neza, zikwirakwizwa neza, kandi zitekanye. Ingano z'amashanyarazi zigena uburyo amashanyarazi atwarwa mu miyoboro y'amashanyarazi, zigahuzwa mu rwego rwa tekiniki n'ubukungu, kandi zigahuzwa n'ikoreshwa ritandukanye. Iyi nkuru irasuzuma ibipimo ngenderwaho n'amahame agenga aya matsinda, hibandwa cyane kuingufu nyinshi z'amashanyarazi (HV),voltage iri hagati (MV),voltage nke (LV)navoltage iri hejuru cyane (UHV)Gushyira mu byiciro ingano y'amashanyarazi mu buryo bw'ingufu ni ingenzi mu gutuma ingufu zikwirakwizwa neza, zikwirakwizwa neza, kandi zitekanye.

Nk'inganda ikomeye yibanda ku mashini zihindura ingufu ziciriritse n'izikoresha ingufu nyinshi, JZP Power Transformer yishimiye gutangaza ko twitabiriye ENLIT Europe 2025—igikorwa cy'ingenzi ku mugabane w'Afurika cyo guhanga udushya mu by'ingufu. Kuva ku ya 18 kugeza ku ya 20 Ugushyingo 2025, tuzerekana ibisubizo byacu bigezweho mu kigo cy'imurikagurisha cya Bilbao (48100 Bilbao, Bizkaia, Esipanye). Dusure kuri Booth 3.F122 kugira ngo umenye uko turimo gushyiraho ahazaza ho kohereza no gukwirakwiza ingufu.

Mu rwego rw’ibikorwa remezo by’ingufu ku isi, JZP ni itsinda ry’abambere ryibanda ku gukwirakwiza ingufu ziciriritse n’izifite ingufu nyinshi—inkingi y’ingenzi mu kohereza, gukwirakwiza no gukoresha ingufu neza. Dufite ubunararibonye bw’imyaka myinshi, ikoranabuhanga rigezweho, n’umuhate udashira wo kuvugurura ireme ry’ingufu, duha imbaraga inganda, ibigo by’imirimo n’imishinga ku isi yose kugira ngo tugere ku bisubizo by’ingufu byizewe, birambye kandi bihendutse.

Switchgear ikora nk'inkingi y'ingufu z'amashanyarazi ziciriritse n'izifite ingufu nyinshi (MV / HV), ikora imirimo itatu y'ingenzi kuri transformers:

• Ese?Gukwirakwiza Ingufu: Itwara amashanyarazi kuva kuri transfomasiyo kugera ku mitwaro binyuze mu byuma bitanga amashanyarazi, utubari tw'imodoka, n'ibikoresho byo kurinda.
• Ese?Uburinzi bw'amakosa: Ihagarika imiyoboro y'amashanyarazi mu masegonda make (urugero, ubushobozi bwo kugabanya umuvuduko wa 31.5kA–40kA) kugira ngo hirindwe kwangirika kw'ibikoresho.
• Ese?Kwishyira mu kato k'umutekano: Igenzura ko ibungabungwa neza binyuze mu gufunga no gufunga ubutaka.

Urugero, sisitemu ya 12kV isaba nibura uburebure bwa 125mm (ifite ubwishingizi bw'umwuka) cyangwa 40mm (ifite ubwishingizi bw'umwuka) kugira ngo hirindwe ko uruziga ruhagarara.

Ese?Isesengura rirambuye ry'ubwoko bwa M&H Voltage Power Electronic Transformer, Imiterere y'imiterere, n'ibipimo by'ingenzi

Hagaragajwe topolojia ya Neutral Point Clamped (NPC). Uretse topolojia ya NPC ifite diode-clamped, topolojia ya NPC irimo kandi ubwoko bwa capacitor iguruka n'ubwoko bwa hybrid clamped, n'ibindi. Ariko, kubera ingano nini ya capacitor, topolojia ya NPC iracyakoresha ibikoresho byo guhindura ibintu bidakora cyangwa bikora mu gufunga. Dufashe urugero rwa topolojia ya diode-clamped multilevel, muri topolojia y'icyiciro cya gatatu cyo gukosora, buri gice cy'icyiciro kigizwe na transistors zihinduranya zicassed na diodes zifatana, zihujwe hamwe na bisi imwe ya DC ifite voltage nyinshi. Inyandiko zatanze topolojia ya PET y'icyiciro kimwe ifite urwego rwo gukosora hakoreshejwe circuit ifite diode y'icyiciro cya kane. Bus imwe ya DC ifite voltage nyinshi ikurikirwa na DABs zinjira-uruhererekane-zisohoka-zikwirakwira, nk'uko bigaragazwa. Iyi topolojia ishobora kwaguka mu buryo bw'icyiciro cya gatatu, kandi umubare w'urwego rwa voltage ushobora guhinduka hashingiwe ku rugero rwa voltage yihanganira igikoresho n'urwego rwa voltage nyinshi ku ruhande rwa voltage nyinshi. Kimwe na topolojia ya MMC, topolojia ya NPC ishobora no gukoreshwa mu cyiciro cyo kwitandukanya, ihuza bisi ya DC ifite voltage nyinshi na transformateur yo kwitandukanya, nk'uko bigaragazwa. Ubuvanganzo bwakoresheje converter ya NPC ifite diode eshatu ku ruhande rwa converter ya resonant ya LLC, buyigenzura kuri prototype ya 166kW/2kV ~ 400V. Ubuvanganzo bwakoresheje circuit ya NPC ifite diode eshatu kuri DAB ifite phase eshatu, bigeza kuri voltage nziza ya DAB n'imiterere y'amashanyarazi.

Topologiya za PET ziratandukanye cyane. Hashingiwe ku mubare w'ibyiciro byo guhindura ingufu, bishobora gushyirwa mu byiciro by'icyiciro kimwe, iby'icyiciro bibiri, n'iby'icyiciro bitatu [7]. Imiterere y'icyiciro kibiri irimo ifite bisi za DC zifite voltage nyinshi n'ifite voltage nkeya, nk'uko bigaragara ku Ishusho ya 1.

Hamwe n’igitekerezo cy’igitekerezo cy’ingufu kuri interineti no gukoresha ikoranabuhanga rigezweho rijyanye n’imiyoboro y’amashanyarazi, igipimo cy’ingufu zishobora kuvugururwa nk’ingufu z’umuyaga n’amashanyarazi ya photovoltaic mu buryo bw’ingufu buriho kiziyongera cyane. Ibi bigaragaza ko imiyoboro y’amashanyarazi y’ejo hazaza izarushaho kuba umuhanga kandi ihindagurika. Muri interineti y’ingufu, uko igipimo cy’abakoresha n’ingufu zikwirakwira kigenda cyiyongera, kohereza amashanyarazi bisaba ubushobozi bwo kugenzura cyane. Mu miyoboro y’amashanyarazi igezweho, imiyoboro y’amashanyarazi igomba kugumana ingufu zihamye kandi nziza mu gihe ihuza umubare munini w’ingufu zishobora kuvugururwa zikwirakwira hamwe no gukurikirana/gucunga imiterere y’imikorere y’imiyoboro y’amashanyarazi. Ibi bisabwa bisaba ingufu zikomeye ku bwenge bw’ibikoresho by’amashanyarazi, mu gihe transformers zisanzwe z’amashanyarazi zihura n’imbogamizi mu mikorere.

Transformateur ifite voltage nyinshi ni igikoresho cy'amashanyarazi cyakorewe guhindura ingufu z'amashanyarazi hagati y'urugero rw'amashanyarazi, akenshi gikora mu rugero rwa110 kV kugeza 500 kVIzi transformateur ni ingenzi cyane mu buryo bwo kohereza ingufu, zigabanya igihombo cy'ingufu mu gihe cyo kohereza ingufu kure, ariko zigatanga amashanyarazi mu buryo bwizewe mu ngo, mu bigo by'ubucuruzi no mu nganda. Urugero, inganda zitanga amashanyarazi ku muvuduko mwinshi, kandi transformateur zihindura uyu muvuduko—ziba ziyongera kugira ngo zikoreshwe cyangwa zigabanye kugira ngo zikoreshwe n'abazikoresha—kugira ngo zirusheho kunoza imikorere n'umutekano.

JZP Transformer ni ikigo gikomeye ku isi mu gukorera urwego rw'ingufu zisubira ku isi. Dufite amateka meza, twatanze ibihumbi bya transformateurs mu mishinga yo kubika ingufu za fotovoltaic no kuzibika muri Amerika ya Ruguru, i Burayi, na Ositaraliya. Ibicuruzwa byacu ntabwo byujuje gusa amahame akomeye nka IEEE, ANSI, CSA, AN, IEC, na BS, ahubwo bifite n'ibyemezo birimo UL, cUL, CSA, CE, SGS, n'ibindi, bishyigikiwe na raporo zuzuye z'ibizamini.
