1. wareegga gacanta ee gacanta
Kani waa wareegtada gacanta lagu maamulo ee adeegsata furayaasha mindida iyo furayaasha wareegga si ay u xakameeyaan hawlgalka socda ee wareegyada kontoroolka mootooyinka asynchronous ee saddex-waji ah
Wareeggu wuxuu leeyahay qaab-dhismeed fudud wuxuuna kaliya ku habboon yahay matoorada yar-yar ee si aan caadi ahayn u bilaabma.Matoorka si toos ah looma koontarooli karo, kamana ilaalin karo koronto eber iyo luminta danab.Ku rakib fiyuusyo FU ah si matoorku u yeesho culays xad-dhaaf ah iyo ilaalinta wareegga gaaban.
2. Wareegga xakamaynta orodka
Bilawga iyo joogsiga mootada waxaa gacanta ku haya badhanka badhanka, xidhiidhiyahana waxa loo isticmaalaa in lagu garto hawlgalka off-ka ee matoorka.
Cilad: Haddii matoorka ku jira wareegga kontoroolka orodka uu si joogto ah u socdo, badhanka bilowga SB waa in had iyo jeer gacanta lagu hayaa.
3. Xakamaynta hawlgalka joogtada ah (xakamaynta dhaqdhaqaaqa dheer)
Bilawga iyo joogsiga mootada waxaa gacanta ku haya badhanka badhanka, xidhiidhiyahana waxa loo isticmaalaa in lagu garto hawlgalka off-ka ee matoorka.
4. Wareegga xakamaynta orodka iyo dhaqdhaqaaqa dheer
Qaar ka mid ah mishiinada wax soo saarka waxay u baahan yihiin in matoorku awood u yeesho inuu dhaqaajiyo socodka iyo dheerba labadaba. Tusaale ahaan, marka qalabka guud ee mishiinka uu ku jiro habka caadiga ah, matoorku si joogto ah ayuu u wareegayaa, taas oo ah, wakhti dheer, halka inta badan loo baahan yahay in la ordo inta lagu jiro komishanka iyo hagaajinta.
1. Jog iyo wareegga kontoroolka dhaqdhaqaaqa dheer ee lagu xakameynayo wareejinta wareejinta
2. Jog iyo wareegyada kontoroolka dhaqdhaqaaqa dheer ee ay gacanta ku hayaan badhamada isku dhafan
Isku soo wada duuboo, furaha lagu ogaanayo kontoroolka dheer ee orodka iyo orodka ee xariiqa ayaa ah inay xaqiijin karto in laanta isku xirta ay isku xirto ka dib marka gariiradda KM la tamarsiiyo.Haddii laanta is-qufulka ah lagu xidhi karo, dhaqdhaqaaq dheer ayaa la gaari karaa, haddii kale kaliya dhaqdhaqaaqa orodka ayaa la gaari karaa.
5. Wareegga kontoroolka hore iyo gadaal
Xakamaynta hore iyo gadaalba waxaa sidoo kale loo yaqaannaa xakamaynta dib-u-celinta, taas oo xaqiijin karta dhaqdhaqaaqa qaybaha wax-soo-saarka labadaba jihooyinka togan iyo kuwa taban inta lagu jiro wax-soo-saarka.Matoorka asynchronous ee saddex-waji ah, si loo xaqiijiyo hor-u-socodka iyo dib-u-celinta kontoroolka, waxay u baahan tahay oo kaliya in ay bedesho isku xigxiga wejiga awooddeeda, taas oo ah, in la hagaajiyo wax kasta oo laba weji ah oo ka mid ah xadhkaha korantada ee saddexda weji ee wareegga ugu weyn.
Waxaa jira laba hab oo caadi ahaan loo isticmaalo xakamaynta: mid waa in la isticmaalo isku-dhafka isku-dhafka ah si loo beddelo taxanaha wajiga, midda kalena waa in la isticmaalo xiriirka ugu muhiimsan ee xiriiriyaha si loo beddelo taxanaha wajiga.Midka hore wuxuu inta badan ku haboon yahay matoorrada u baahan horudhac joogta ah iyo dib u celin, halka kan dambe uu inta badan ku habboon yahay matoorada u baahan wareegyo badan oo hore iyo gadaal ah.
1. Wareegga xakamaynta-joojinta-celinta ee togan
Dhibaatada ugu weyn ee koronto-ku-xirnaanta hore iyo dib-u-celinta kontoroolka kontoroolka ayaa ah in marka laga gudbayo isteerinka kale, batoonka joogsiga ee SB1 waa in marka hore la riixaa, kala-guurka si toos ah looma samayn karo, taas oo iska cad in ay tahay mid aad u dhib badan.
2. wareegga kontoroolka hore-u-rogista-joojinta
Wareeggani wuxuu isku daraa faa'iidooyinka isku-xirnaanta korantada iyo isku-xidhka badhanka, waana wareeg dhammaystiran oo aan buuxin karin oo keliya shuruudaha bilawga tooska ah ee hore iyo dib-u-celinta, laakiin sidoo kale waxay leedahay badbaado iyo isku-kalsoonaan sare.
Isku xirka ilaalinta khadka
(1) Ilaalinta gaaban ee wareegga wareegga ugu weyn waxaa gooyaa dhalaalka fiyuuska haddii ay dhacdo wareeg gaaban.
(2) Ilaalinta culeyska xad dhaafka ah waxaa lagu xaqiijin karaa gudbinta kulaylka.Sababtoo ah inertia kulaylka ee gudbinta kulaylku waa mid aad u weyn, xitaa haddii hadda dhowr jeer la qiimeeyay uu ku qulqulo walxaha kulaylka, gudbinta kulaylku isla markiiba ma dhaqmi doonto.Sidaa darteed, marka wakhtiga bilawga ah ee matoorku aanu aad u dheerayn, gudbinta kulaylku waxay u adkeysan kartaa saameynta bilawga hadda ee matoorka mana dhaqmi doonto.Kaliya marka matoorku uu ku badan yahay waqti dheer, wuu dhaqmi doonaa, gooyaa wareegga xakamaynta, gariiradda xiriiriyaha ayaa lumin doonta awoodda, gooyn doonta wareegga ugu weyn ee matoorka, oo ogaan doonta ilaalinta culeyska.
(3) Ilaalinta korantada iyo korantada yar Korantada yar iyo ilaalinta korantada yar waxaa lagu xaqiiqsadaa xiriirka is-qufulka ee xiriiriyaha KM.Hawlgalka caadiga ah ee matoorka, korantada korantada ayaa baaba'a ama hoos u dhacda sabab qaar ka mid ah. Marka danabku uu ka hooseeyo korantada la sii daayo ee gariiradda xiriiriyaha, xiriiriyaha ayaa la sii daayaa, xiriirka is-qufulka waa la gooyaa, xiriirka ugu muhiimsan waa la gooyaa, gooyaa awoodda mootada. , matoorku istaago.Haddii korontadu ay caadi ku soo noqoto, sababtoo ah is-qufulka sii-deynta, matoorku ma bilaabi doono keligiis, isaga oo iska ilaalinaya shilalka.
Hababka bilowga wareegga kore ee kor ku xusan waa bilowga korantada buuxda.
Marka awoodda isbeddelku ogolaato, mishiinka asynchronous-ka-qafiska ah waa in si toos ah loo bilaabo tamarta buuxda ee suurtogalka ah, taas oo aan hagaajin karin oo kaliya kalsoonida wareegga xakamaynta, laakiin sidoo kale waxay yaraynaysaa shaqada dayactirka ee qalabka korontada.
6. Wareeg-hoos u bilaw wareegga matoorka asynchronous
• Bilowga korantada buuxda ee matoorka asynchronous wuxuu guud ahaan gaari karaa 4-7 jeer inta hadda la qiimeeyay.Bilawga xad-dhaafka ah ee hadda socda wuxuu yareynayaa nolosha matoorka, wuxuu sababi doonaa koronta labaad ee transformer-ka inuu si aad ah hoos ugu dhaco, hoos u dhigo qulqulka bilawga matoorka laftiisa, xitaa wuxuu ka dhigayaa matoorku inuu awoodi waayo inuu bilaabo gabi ahaanba, wuxuuna sidoo kale saameeyaa shaqada caadiga ah ee kuwa kale. qalabka ku jira shabakad koronto oo isku mid ah.Sidee lagu qiyaasaa in matoorku ku bilaabi karo danab buuxa?
Guud ahaan, kuwa leh awoodda matoorka ee ka hooseeya 10kW si toos ah ayaa loo bilaabi karaa.Haddii matoorka asynchronous ee ka sarreeya 10kW loo oggol yahay inuu si toos ah u bilaabo waxay ku xiran tahay saamiga awoodda mootada iyo awoodda korontadu.
• Matoor awood la siiyay, guud ahaan isticmaal qaacidooyinka soo socda si aad u qiyaasto.
•Iq/Ie≤3/4+ Awood beddelka korontadu (kVA)/[4× awoodda mootooyinka (kVA)
• Qaaciddada, Iq-motor danab buuxa oo hadda bilaabmaya (A); Ie — mooto lagu qiimeeyay hadda (A).
Haddii natiijada xisaabinta ay ku qanacdo qaacidada sare ee sare, guud ahaan waa suurtogal in lagu bilaabo cadaadis buuxa, haddii kale, looma oggola in lagu bilaabo cadaadis buuxa, iyo bilawga korantada ee la dhimay waa in la tixgeliyaa.
• Mararka qaarkood, si loo xaddido loona yareeyo saamaynta dabaysha bilawga ah ee qalabka makaanikada, matoorka u oggolaanaya bilawga korantada buuxa sidoo kale wuxuu qaataa habka bilawga korantada ee la dhimay.
• Waxaa jira dhowr habab oo hoos hoos loogu bilaabayo matoorada daba-qallaalka ah ee asynchronous-ka: iska caabinta wareegga wareegga wareegga (ama falcelinta) hoos-u-dhigga bilowga, beddelka-is-beddelka tallaabo-hoos-u-bilaabida, Y-△ tallaabo-hoos bilaw, △-△ tallaabo Hababkan waxaa loo isticmaalaa in lagu xaddido hadda bilawga ah (guud ahaan, hadda bilawga ah ka dib dhimista danabku waa 2-3 jeer heerka hadda la qiimeeyay ee matoorka), la yareeyo hoos u dhaca tamarta korontada, iyo in la hubiyo hawlgalka caadiga ah ee qalabka korontada ee isticmaale kasta.
1. Iska caabin taxane ah (ama falcelin) wareegga kontoroolka bilawga ah ee hoos u dhaca
Inta lagu jiro habka bilawga ah ee matoorka, caabbinta (ama falcelinta) ayaa inta badan ku xiran si isdaba-joog ah wareegga seddex-waji ee stator si loo yareeyo danabka ku jira dabaylaha stator, si matoorka loo bilaabi karo korantada la dhimay si loo gaaro ujeedada ee xaddidaya bilowga hadda.Marka xawaaraha matoorku uu ku dhawaado qiimaha la qiimeeyay, jar iska caabbinta taxanaha ah (ama falcelinta), si uu matoorku u galo shaqada caadiga ah ee tamarta buuxda.Fikradda naqshadeynta ee wareegga noocan oo kale ah ayaa badanaa ah in la isticmaalo mabda'a wakhtiga si loo gooyo iska caabinta (ama falcelinta) ee taxanaha ah marka la bilaabayo dhamaystirka habka bilawga ah.
Iska caabbinta xadhigga Stator-ka-soo-baxa wareegga kontoroolka bilawga ah
• Faa'iidada bilawga caabbinta taxanaha ah waa in wareegga xakamaynta uu leeyahay qaab-dhismeed fudud, qiimo jaban, ficil la isku halleyn karo, koronto koronto, oo ku habboon hubinta tayada shabakada korontada.Si kastaba ha ahaatee, ay sabab u tahay dhimista danab ee iska caabin ah string stator ah, bilowga hadda hoos u qaybsanaan in danab stator ah, iyo labilawga bilawga hoos u sida ay times square of ratio danab danab.Isla mar ahaantaana, bilaw kastaa wuxuu cunaa awood badan.Sidaa darteed, mashiinka saddex-waji-squirrel-cage asynchronous motor wuxuu qaataa habka bilawga ah ee iska caabbinta hoos-u-dhaca, kaas oo kaliya ku habboon matoorada yar-yar iyo kuwa dhexdhexaadka ah ee u baahan bilawga fudud iyo munaasabadaha bilawga ah ee aan soo noqnoqon.Matoorada awooda waaweyn inta badan waxay isticmaalaan falcelinta taxana ah ee hoos u socota bilawga.
2. Xadhiga autotransformer tallaabo-hoos u bilaw wareegga xakamaynta
• In wareegga xakamaynta auto-transformer tallaabo-hoos bilaabay, xaddidaya hadda bilowga ah ee mootada waxaa xaqiiqo ah tallaabada hoos-hoos ee auto-transformer.Aasaaska is-beddelka is-beddelka wuxuu ku xiran yahay korontadu, iyo kan labaad ee autotransformer wuxuu ku xiran yahay matoorka.Dugsiga sare ee autotransformer guud ahaan wuxuu leeyahay 3 qasabad, iyo 3 nooc oo danab ah oo qiimayaal kala duwan ah ayaa la heli karaa.Marka la isticmaalo, waxaa loo dooran karaa dabacsanaan iyadoo loo eegayo shuruudaha bilawga hadda iyo bilowga.Marka matoorku bilaabmo, danabka uu helo dabaylaha stator-ku waa tamarta labaad ee autotransformer. Marka bilawga la dhammeeyo, autotransformer waa la gooyaa, matoorku wuxuu si toos ah ugu xiran yahay qalabka korontada, taas oo ah, korantada asaasiga ah ee autotransformer ayaa la helayaa, matoorku wuxuu galaa hawl gal buuxda.Noocan autotransformer waxaa badanaa loo tixraacaa magdhow bilow ah.
• Inta lagu jiro habka bilawga ah ee bilawga ah ee autotransformer, saamiga bilawga bilawga ah ee bilawga bilawga ah ayaa hoos u dhigaya labajibbaaran ee saamiga isbeddelka.Marka la eego shuruudaha helitaanka isla bilawga bilawga ah, hadda laga helay korantada korantada ee autotransformer-ka bilawga bilawga ah ayaa aad uga yar marka loo eego hoos u dhigista iska caabinta bilawga ah, saameynta hadda ee shabakada ayaa yar, iyo khasaaraha korontada waa yar yahay.Sidaa darteed, autotransformer-ka waxaa loo yaqaan magdhow bilow ah.Si kale haddii loo dhigo, haddii bilawga hadda la midka ah ee cabbirka la midka ah laga helo korantada korantada, hoos udhaca ka bilaabmaya autotransformer wuxuu dhalin doonaa qulqulka bilawga weyn.Habkan bilawga ah waxaa badanaa loo isticmaalaa matoorada leh awood weyn iyo hawlgalka caadiga ah ee xiriirka xiddigaha.Khasaaraha ayaa ah in autotransformer uu qaali yahay, qaabdhismeedka iska caabbinta qaraabo waa mid adag, mugga waa weyn yahay, waxaana loo qaabeeyey oo la soo saaray iyadoo loo eegayo nidaamka shaqada ee joojinta, sidaas darteed hawlgal joogto ah lama ogola.
3. Y-△ wareegga kontoroolka bilawga ah ee hoos u dhaca
Faa'iidada saddex-waji-squirrel-cage asynchronous motor leh Y-△ tallaabo-hoos bilawga ah waa: marka dabaylaha stator ku xiran yahay ee star, danab bilowga ah waa 1/3 ka mid ah marka xiriirka delta si toos ah loo isticmaalo, iyo bilawga hadda waa 1/3 marka la isticmaalo isku xirka delta. / 3, markaa sifooyinka hadda bilawga ah ayaa wanaagsan, wareeggu waa sahlan yahay, maalgashiguna wuu yar yahay.Khasaaraha ayaa ah in qulqulka bilawga ah sidoo kale la yareeyo 1/3 ee habka isku xirka delta, iyo sifooyinka qulqulka ayaa liita.Markaa khadkani waxa uu ku haboon yahay culayska fudud ama bilaa-load ee bilowga ah.Intaa waxaa dheer, waa in la ogaadaa in joogtaynta jihada wareegga waa in fiiro gaar ah loo yeesho marka la isku xirayo Y-
