Tiknoolajiyada braking degdega ah ee isku xidhka awooda sare leh

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.Badankoodu waxay adeegsadaan biriiga korantada, kuwaas oo isticmaala cadaadiska ka dhasha ilo-biyoodyada 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.

Joojinta korantada waxa ay dhalisaa quwadda korantada ee ka soo horjeeda isteerinka inta lagu jiro habka joogsiga mootada, kaas oo u shaqeeya sidii xooga bareegga lagu joojiyo 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 wanaagsan 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 wuxuu u baahan yahay in lagu xidho dhinaca DC ee beddelka oo keliya waxa lagu dabaqi karaa rogo-rogayaasha wata baska caadiga ah ee DC.Xaaladdan oo kale, AC tamar-cunida iska caabbinta bireega waxay si toos ah ugu xiran tahay matoorka dhinaca AC, kaas oo leh cabbir codsi oo ballaaran.

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 biraynta iyo matoorka.Duruufaha caadiga ah marka ay jiraan, vacuum circuit breaker ayaa ku jira xaalad furan oo 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 mootada 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 xawaaraha hadda taagan ee stator iyo braking motor synchronous, si loo gaaro 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 istaagi karo wakhti cayiman (in ka yar 300 ilbiriqsi) xaalad degdeg ah, nidaamka joojinta degdega ah ee ku salaysan tamarta iska caabinta bareegga isticmaalka ayaa la habeeyey.

Nidaamka wadista korantada waxaa ka mid ah inverter-voltage-ka sare, matoor laba-laaban leh oo awood sare leh, qalab kicin, 2 qaybood oo 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 mootada, iyo afar armaajooyin koronto-gooye sare leh 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 tamarta sare AH13 iyo AH23 waa la xiray, caabiyaha bireega ayaa bilaabay inuu shaqeeyo.Jaantuska jaantuska nidaamka bareegga waa sida soo socota:

Halbeegyada farsamada ee resistor weji kasta (R1A, R1B, R1C, R2A, R2B, R2C,) waa sida soo socota:

Farsamadani waxay adeegsataa bareegga korantada si ay u garwaaqsato joojinta 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 korantada waxay leedahay sifooyinka soo socda:
