Ka dib marka la gooyo sahayda korontada, matoorku wuxuu weli u baahan yahay inuu wareego muddo ka hor inta uusan istaagin sababtoo ah dhaqdhaqaaqiisa. Xaaladaha shaqada ee dhabta ah, culeysyada qaarkood waxay u baahan yihiin in matoorku si dhakhso ah u istaago, taas oo u baahan xakamaynta bareegga ee matoorka.Waxa loogu yeero bareegga waa in la siiyo matoorka qulqulka ka soo horjeeda jihada wareegga si uu dhaqso u istaago.Guud ahaan waxaa jira laba nooc oo hababka bareegga ah: bareegga makaanikada iyo bareegga korontada.
Baarista makaanikada waxay isticmaashaa qaab dhismeed si ay u dhamaystirto biriiga. Intooda badan waxay adeegsadaan biriiga korantada, kuwaas oo isticmaala cadaadiska ka yimaada ilo si ay ugu riixaan suufka biriiga (kabaha biriiga) si ay u sameeyaan is-qab-qabsi leh giraangiraha biriiga.Farriinta makaanikada waxay leedahay isku hallayn sare, laakiin waxay soo saari doontaa gariir marka biriiga la jarayo, garaaca bareegu waa yar yahay. Waxaa guud ahaan loo isticmaalaa xaaladaha ay ku jiraan firfircooni yar iyo xoog.
biriiga korantada waxa ay dhalisaa quwad korantada oo ka soo horjeeda isteerinka inta lagu jiro habka joogsiga mootada, kaas oo u shaqeeya sidii xooga bareegga ee lagu joojinayo mootada.Hababka biriiga korantada waxaa ka mid ah braking roga, bareegga firfircoon, iyo bareegga dib u curashada.Waxaa ka mid ah, bareegga isku xirka gadaale waxaa guud ahaan loo isticmaalaa joojinta degdega ah ee matoorrada korantada yar iyo kuwa yar yar; biriiga dib u curinta ayaa shuruudo gaar ah u leh beddelayaasha soo noqnoqda. Guud ahaan, matoorada yar yar iyo kuwa dhexdhexaadka ah ayaa loo isticmaalaa joojinta degdega ah. Waxqabadka bareegga waa fiican yahay, laakiin qiimuhu aad buu u sarreeyaa, korontadu waa inay awood u yeelato inay aqbasho. Jawaab celinta tamarta ayaa ka dhigaysa mid aan suurtagal ahayn in la jebiyo matoorada tamarta sare leh.
Marka loo eego booska uu taagan yahay iska caabiyaha bareegga, biriiga tamarta cunaysa waxaa loo qaybin karaa biriiga tamar-cuntada ee DC iyo bareegga tamarta-cunaya. Resistors-ka tamar-cunida ee DC-ku wuxuu u baahan yahay in lagu xidho dhinaca DC ee beddelka oo keliya waxa lagu dabaqi karaa rogo-rogayaasha wata baska DC-ga caadiga ah. Xaaladdan oo kale, AC tamar-cunida iska caabbinta bireega waxay si toos ah ugu xidhan tahay matoorka dhinaca AC, kaas oo leh kala duwanaansho codsi oo ballaadhan.
Iska caabiyaha bareegga ayaa loo habeeyey dhanka mootada si uu u isticmaalo tamarta matoorka si loo gaaro joogsiga degdega ah ee mootada. Xakamaynta wareegtada faakuumka sare ee korantada ayaa lagu habeeyey inta u dhaxaysa iska caabiyaha bireega iyo matoorka. Duruufaha caadiga ah marka ay jiraan, vacuum circuit breaker ayaa ku jira xaalad furan, matoorku waa caadi. Nidaaminta xawaaraha ama hawlgalka soo noqnoqda korantada, xaalad degdeg ah, furaha wareegga wareegga ee u dhexeeya mootada iyo beddelaha soo noqnoqda ama korantada korantada waa la furayaa, waxaana la xiraa furaha wareegga wareegga ee u dhexeeya matoorka iyo iska caabiyaha braking, iyo isticmaalka tamarta biriiga matoorka waxaa lagu gartaa caabiyaha bireega. , si loo gaaro saamaynta baarkin degdeg ah.Jaantuska hal xariiqa nidaamka waa sida soo socota:
Jaantuska Hal Xariiqda Degdegga ah
Habka bareegga degdega ah, iyo marka loo eego shuruudaha wakhtiga desceleration, xamaasadda xamaasadda ayaa la hagaajiyaa si loo hagaajiyo istator-ka hadda iyo biriiga ee matoorka synchronous, taas oo lagu gaadhayo xakamaynta deceleration degdeg ah oo la xakameyn karo ee mootada.
Mashruuca sariirta tijaabada ah, maadaama shabkada korantada ee warshadu aanay ogolayn jawaab celinta korantada, si loo hubiyo in nidaamka korantadu uu si badbaado leh u joogsan karo wakhti cayiman gudahood (in ka yar 300 ilbiriqsi) xaalad degdeg ah, nidaamka joogsiga degdega ah ee ku salaysan tamarta iska caabinta bareegga isticmaalka ayaa la habeeyey.
Habka wadista korantada waxaa ka mid ah inverter koronto-sare ah, koronto laba-laabanaysa matoor sare oo koronto ah, qalab kicin, 2 qaybood oo iska caabiyeyaasha bireega ah, iyo 4 armaajooyinka korantada sare leh. Inverter-ka-sare waxa loo istcmaalay in lagu xaqiijiyo bilawga soo noqnoqda doorsoomiyaha ee bilawga iyo xakamaynta xawaaraha matoorka-sare. Aaladaha xakamaynta iyo kicinta ayaa loo istcimaalay si ay u siiyaan kicinta hadda ee mootada, iyo afar armaajooyin koronto-gooye sare ah ayaa loo isticmaalaa si loo xaqiijiyo beddelka habaynta xawaaraha beddelka soo noqnoqda iyo bareegga mootada.
Inta lagu jiro joojinta degdega ah, armaajooyinka korantada sare AH15 iyo AH25 waa la furay, armaajooyinka korantada sare AH13 iyo AH23 waa la xiray, caabiyaha bireega ayaa bilaabay inuu shaqeeyo. Jaantuska jaantuska nidaamka bareegga waa sida soo socota:
jaantuska nidaamka bareegga
Halbeegyada farsamada ee resistor weji kasta (R1A, R1B, R1C, R2A, R2B, R2C,) waa sida soo socota:
- Tamarta bareegga (ugu badnaan): 25MJ;
- Iska caabin qabow: 290Ω± 5%;
- danab la qiimeeyay: 6.374kV;
- Awoodda la qiimeeyay: 140kW;
- Awoodda culeyska badan: 150%, 60S;
- Korontada ugu badan: 8kV;
- Habka qaboojinta: qaboojinta dabiiciga ah;
- Waqtiga shaqada: 300S.
Farsamadani waxay adeegsataa bareega koronto si ay u ogaato bareegga matoorada awoodda sare leh. Waxay khusaysaa falcelinta armature-ka ee matoorrada isku midka ah iyo mabda'a isticmaalka tamarta joojinta si loo jebiyo matoorada.
Inta lagu jiro habka bareegga oo dhan, garaaca bareegga waxaa lagu xakameyn karaa iyadoo la xakameynayo dhaqdhaqaaqa kacsanaanta. Joojinta korontada waxay leedahay sifooyinka soo socda:
- Waxay ku siin kartaa garaaca bareegga weyn ee looga baahan yahay bareegga degdegga ah ee cutubka oo waxay ku gaadhi kartaa saamayn braking oo heer sare ah;
- Wakhtiga dhimashadu waa gaaban yahay oo bareegga waa la samayn karaa inta lagu jiro hawsha;
- Inta lagu jiro habka bareegga, ma jiraan habab ay ka mid yihiin bareegga iyo giraangiraha kuwaas oo keena nidaamka bareegga farsamada inuu isku xoqo midba midka kale, taas oo keeneysa kalsooni sare;
- Nidaamka bareegga degdega ah wuxuu u shaqeyn karaa kaligiis sidii nidaam madax-bannaan, ama waxaa lagu dhex dari karaa nidaamyada kale ee kantaroolka sida nidaam hoose, oo leh nidaam is-dhexgalka dabacsan.
