Tareenka dheereeya ee maglev ee ka shaqeeya Shanghai waa tareen TR08 maglev ah oo laga keenay Jarmalka, kaas oo isticmaala matoor dheer oo toosan oo toosan iyo nidaamka levitation conduction joogto ah. Nidaamkeeda korantada jiidista waxa lagu muujiyay sawirka 1, wuxuuna ka kooban yahay qaybaha ugu muhiimsan sida Transformer-ka korantada sare leh (110kv/20kv), Transformer-ka wax-soo-gelinta, beddelaha wax-soo-gelinta, roga-dhaliye, iyo wax-soo-saarka wax-soo-saarka.
Nidaamka sahayda korantada ee tareenka maglev waxaa laga soo rogaa korantada 110kv grid ilaa 20kv iyada oo loo marayo transformer-ka korantada sare, ka dibna loo rogo danab DC ah ± 2500v by transformer-ka wax gelinta iyo beddelaha wax gelinta. Korantada DC ee ka socota isku xirka DC waxaa loo beddelaa awood saddex-waji AC ah oo leh soo noqnoqoshada doorsoome (0 ~ 300Hz), baaxadda doorsoome (0 ~ × 4.3kv), iyo xagal waji la hagaajin karo (0 ~ 360 °) saddex waji saddex -rogrogiyaha dhibicda.Beddeliyaha tareenka maglev wuxuu leeyahay laba qaab oo shaqo:
(1) Habka wax-soo-saarka tooska ah ee is-beddelka ballaca garaaca wadnaha inverter waa habka wax-soo-saarka marka matoorku uu ku shaqeeyo soo noqnoqoshada hooseeya, oo leh inta jeer ee beddelka 0 ~ 70Hz. Waqtigan, laba qaybood oo rogaal-celiyeyaasha saddex-dhibcood ah ayaa si is-bar-bar socda isugu xidhan, wax-soo-saarkuna waxa uu ku xidhan yahay dabaylaha aasaasiga ah ee wax-soo-saarka sida ku cad sawirka 1-aad. fal-celinta dheellitirka isbar-bar-tagga, iyo sidoo kale wuxuu ciyaaraa door shaandhayn.
(2) Habka wax-soo-saarka Transformer waa habka wax-soo-saarka marka matoorku uu ku shaqeeyo inta jeer ee sarreeya, oo leh inta jeer ee beddelka 30Hz ~ 300Hz. Waqtigaan, labada qaybood ee beddelayaasha ee ku jira beddelaha jiidka weyn waxay si taxane ah ugu xidhan yihiin dhinaca hore ee wax-soo-saarka, wax-soo-saarku wuxuu soo baxayaa ka dib markii wax-soo-saarka wax-soo-saarka uu kor u qaado tamarta.

3.1 beddelka wax soo gelinta
Marxaladda hore ee beddelaha wax-soo-gelinta waxa uu ka kooban yahay koronto-bixiye-voltage-sare iyo qalab wax-is-beddele. Transformer-ku waxa uu ka kooban yahay laba Transformers rectifier, kuwaas oo shaqadoodu tahay in la yareeyo korantada korantada sare ee korontada iyada oo loo marayo transformer-ka sare ka dibna loo diro beddelaha wax-gelinta. Qalabka hagaajinta tayada sare leh ee awoodda weyn leh, si loo hagaajiyo waxtarka hagaajinta, laba qaybood oo ah buundooyinka hagaajinta garaaca wadnaha 6 ayaa la isticmaalaa. Qayb kasta oo ka mid ah transformers-ka toosiye waxa ku shaqeeya laba qaybood oo ah dabaylo saddex waji ah, hal y iyo hal isku xidhid d. Nidaamka beddelka ee joogtada ahi waxa uu qaataa qorshe ah saddex weji-hal-hal ah oo saddex-wareeg leh, kuwaas oo ku xidhan si ay u sameeyaan y/y, kooxda d nidaamka beddelka beddelka ee lagu muujiyey Jaantuska 2 iyada oo loo marayo xidhiidhka loo qoondeeyey ee dabayl kasta. Faa'iidooyinkeeda ugu waaweyn waa:
(1) Awood yar oo firaaqo ah, ka dhaqaale badan;
(2) Awood yar oo keli ah, oo sahlan in la buuxiyo shuruudaha gaadiidka ee cabbirka qalabka;
(3) Saddexda dabaysha waxa lagu habayn karaa isla tiirka xudunta u ah, taas oo ka caawinaysa in la yareeyo khasaaraha is-waafajinta ah ee beddelka.
Si loo xakameeyo korantada isku xirka DC ee wareegga dhexdhexaadka ah oo loo yareeyo kicinta dhinaca-grid-ka, dib-u-haye kasta oo nidaamku wuxuu ka kooban yahay buundada hagaajinta lix-waji saddex-waji oo si buuxda loo kontoroolo iyo lix-pulse saddex-waji oo aan la xakameynin buundada hagaajinta si taxane ah, sida ku cad Jaantuska 2. Sidan, labada qaybood ee dib-u-hagaajiyayaashu waxay isku xiran yihiin si isdaba-joog ah, barta dhexena waxay salka ku haysaa iska caabin sare (sida ku cad sawirka 1), samaynta isku-xidhka wareegga DC-ga ah ee saddexda suurtagal ah. . Korontada isku xirka DC-ga waa la kontarooli karo, laga bilaabo 2 × 1500V ilaa 2 × 2500V, iyo hadda la qiimeeyay waa 3200A. Si loo helo hadda siman oo DC ah, reactor-ka fududeeya ayaa si taxane ah ugu xidhan wareegga dhexe. Isla mar ahaantaana, si looga hortago buundada hagaajinta iyo isku xirka DC inay kor u kacdo, ilaalinta korantada dhinaca DC ayaa la qaatay. Isku xirka dhexe ee DC, waxaa jira thyristors iyo iska caabin awood sare leh oo leh ilaalinta dheecaanka sida aaladaha nuugista dhinaca DC si loo xakameeyo korontada. Intaa waxaa dheer, barta dhexe ee isku xirka DC-ga ee wareegga dhexdhexaadka ah wuxuu ku salaysan yahay ilaalinta caabbinta sare waxayna leedahay muuqaal qalad ah.
3.2 rogrogayaasha jiidashada
(1) Qaab-dhismeedka beddelka
Qaab dhismeedka hal weji ee rogaha saddexda weji ee tareenka Shanghai Maglev ayaa lagu muujiyay sawirka 3. Tuubada ugu weyni waxay qabataa GTO qalab koontarool buuxa ah. Wareegga ugu weyn wuxuu qaataa laba tuubbo oo waaweyn oo taxane ah oo leh diode isku dhejinaya barta dhexe. Wareegtan waxa kale oo loo yaqaan saddex-dhibcood (ama saddex-heer bar-dhexe oo ku dhegsan) rogaye. Tani waxay hoos u dhigi kartaa tuubada ugu muhiimsan ee u adkeysiga danabka kala bar. Isla mar ahaantaana, isla isla inta jeer ee isku beddelka iyo habka xakamaynta, harmonics-ka korantada wax soo saarkeeda ama hadda ayaa ka yar kuwa labada heer, iyo korantada-qaabka guud ee ay dhaliso danab wax-soo-saarka ee dhamaadka mootada ayaa sidoo kale ka yar. , taas oo faa'iido u leh in la kordhiyo nolosha adeegga matoorka.
Afarta tuubooyin ee cudud kasta oo weji ah waxay leeyihiin saddex isku-dhafan oo kala duwan, waxayna soo saaraan koronto kala duwan siday u kala horreeyaan (eeg Shaxda 1). Korantada ugu sarreysa ee GTO-ga ugu weyn waa 4.5kV, halka ugu sarreeyana hadda waa 4.3ka. Wareegtada saddexda dhibcood leh waxay u baahan tahay in V1-da iyo V4-ga ugu weyn aan la shidin karin isku mar, iyo garaaca wadnaha ee V1 iyo V3, V2 iyo V4 waa kuwo iska soo horjeeda. Intaa waxaa dheer, beddelka ugu weyn ee kor ku xusan waa in uu u hoggaansamaa mabda'a marka hore iyo ka dib.
Inverter-ka saddex-heer ah waxaa lagu horumariyaa iyadoo lagu salaynayo rogaha laba-heer ah. Soo bandhigida tignoolajiyada kontoroolka qaan-gaadhka ah ee rogaha laba-heer ee rogayaasha saddex-heer ayaa sameeyay istaraatiijiyado kala duwan oo lagu xakameynayo inverter.

Wareegga wadista GTO ee awoodda sare leh waa inuu marka hore xalliyo dhibaatooyinka go'doominta iyo ka-hortagga faragelinta. Calaamadaha garaaca garaaca wadnaha ee GTO ee rookaha ugu weyn ee tareenka Shanghai Maglev Train waxaa lagu kala qaadaa fiilada fiber indhaha, markaa dhibaatooyinka go'doominta iyo faragelinta ka hortagga ayaa la xalliyaa, iyadoo la hubinayo saxnaanta garaaca wadnaha GTO iyo si aan toos ahayn loo hubiyo badbaadada wadista Maglev Tareen. Intaa waxaa dheer, furaha in wareegga wadida GTO ee awoodda sare leh uu si caadi ah u shaqeyn karo waxay ku jirtaa sahayda korontada. Baaxadda garaaca garaaca albaabka GTO waa inuu ahaadaa mid sare oo ku filan, iyo cidhifkeeda hogaamineed waa inuu ahaadaa mid taajir ah, halka cidhifkeeduna yahay mid dabacsan. Si loo buuxiyo shuruudahan, sahayda korantada albaabka ee GTO ee ku taal rookaha ugu weyn ee tareenka Maglev Train waa 45V/27A, iyo calaamada cidhifka iyo calaamada korantada ee garaaca garaaca GTO ayaa dib loogu soo celinayaa nidaamka xakamaynta. Intaa waxaa dheer, rookaha ugu weyn ee tareenka Shanghai Maglev Train wuxuu qaataa ilaalin kala duwan: ilaalinta xad-dhaafka ah ee jebiya wareegga biriiga, ilaalinta xad dhaafka ah ee xadka hadda, joojinta garaaca wadnaha iyo ogaanshaha cilladaha dhulka.
(3) wareegga nuugista
Waxaa jira wareegyo badan oo nuugista GTO ah. Wareegga nuugista ee rookaha ugu muhiimsan ee saddexda heer ee tareenka Shanghai Maglev Train waxaa lagu muujiyey Jaantuska 3. Wareegga nuugista waa inuu xaqiijiyaa in di / dt iyo du / dt ee GTO aysan dhaafin qiyamka la oggol yahay ee la cayimay marka ay tahay shaqaynaysa. Sidan, wareegga nuugista ee GTO waa inuu lahaadaa inductor iyo capacitor C. Jaantuska 3, inductors L1, L2 iyo GTO waxay ku xiran yihiin taxane si loo xaddido di/dt ee GTO. Diodes-yada D11, D12, resistor R1 iyo inductor L1 waxay sameeyaan wareegga tamarta ee soo-saarka laftiisa. Capacitors C11 iyo C12 waxaa loo isticmaalaa in lagu xaddido du/dt ee GTO, iyo diodes D12 iyo D13 waxay sameeyaan wareegga tamarta ee capacitor. Marka la barbar dhigo wareegga nuugista RCD, wareegga nuugista ee kor ku xusan wuxuu ku darayaa capacitor weyn C12, sidaas darteed xirmada nuugista ee C11 waa nus ka mid ah qiimaha awoodda ee wareegga nuugista RCD, sidaas darteed khasaaraha sidoo kale waa la dhimay kala badh; Isla mar ahaantaana, capacitor C12 wuxuu ciyaaraa door xirida danab, kaas oo loo isticmaalo in lagu xakameeyo daminta dabka ee GTO. 1500kva rogaye, luminta wareeggan nuugista ayaa qiyaas ahaan la mid ah tan wareegga nuugista asymmetrical.
