Isimiso Sokusebenza Se-Voltage Regulator ye-Diesel Generator

I-AVR isenhliziyweni yamadivayisi avame ukubizwa ngokuthi ama-power conditioners noma izinzisi zamandla.I-conditioner yamandla ejwayelekile iyisilawuli se-voltage esizenzakalelayo esihlanganiswe namandla ekhwalithi eyodwa noma ngaphezulu, njengalokhu:

1) Ukunciphisa ukucindezeleka

2) Ukuvikelwa kwesekethe emfushane (i-circuit breaker)

3) Ukunciphisa umsindo womugqa

4) Ukulinganisa kwamandla kagesi wesigaba ukuya kwesinye

5) Ukuhlunga kwe-Harmonic, njll.

Ama-conditioner kagesi ngokuvamile asetshenziswa ku-voltage ephansi (<600V) izinhlelo kanye nosayizi abangaphansi kuka-2,000KVA.

Ngokuvamile, i-AC automatic voltage regulator (AVR) iyithuluzi eliklanyelwe ukulawula i-voltage ngokuzenzakalelayo isethi ye-diesel generator , okungukuthi, ukuthatha izinga le-voltage eguquguqukayo bese uyiguqula ibe ileveli ye-voltage engashintshi.

Umgomo wokusebenza we-AVR

I-voltage regulator iyisisetshenziswa sokulungisa esilawula i-voltage ye-generator ephumayo ngaphakathi kwebanga elithile.Umsebenzi wayo ukulawula ngokuzenzakalelayo i-voltage ye-generator nokuyigcina ingashintshi lapho ijubane elijikelezayo lejeneretha lishintsha, ukuze kuvinjwe amandla kagesi aphehla ugesi ukuba abe phezulu kakhulu ukuze ashise izinto zikagesi futhi kubangele ukuthi ibhethri lishaje ngokweqile.Ngesikhathi esifanayo, iphinde ivimbele i-voltage ye-generator ekubeni iphansi kakhulu, okuholela ekungasebenzini kahle kwezinto zikagesi kanye nokushajwa kwebhethri okwanele.

Njengoba isilinganiso sokudluliswa kwe-generator kuya enjinini sinqunyiwe, isivinini se-generator sizoshintsha ngokushintsha kwesivinini senjini.Ukunikezwa kwamandla kwejeneretha ezintweni zikagesi kanye nokushaja ibhethri kokubili kudinga i-voltage yayo ukuthi izinze, ngakho-ke kuyadingeka ukulungisa ugesi ophumayo wejeneretha uma i-voltage igcinwa enanini elithile ngokuyisisekelo.

Isilawuli sejeneretha esivumelanayo esigcina i-voltage yejeneretha evumelanayo ngenani elinqunywe kusengaphambili noma sishintsha i-terminal voltage njengoba kuhleliwe.

Lapho i-terminal voltage namandla asebenzayo e-synchronous motor eshintsha, amandla aphumayo e-exciter alawulwa ngokuzenzekelayo ngokuya ngesignali yempendulo ehambisanayo ukuze kufezwe injongo yokulawula ngokuzenzakalelayo i-terminal voltage noma amandla asebenzayo enjini ehambisanayo.

Ngokusho kwesimiso sokusebenza, isilawuli se-voltage ye-alternator sihlukaniswe:

1. Isilawuli se-voltage yohlobo lokuxhumana

Isilawuli se-voltage yohlobo lokuxhumana sasetshenziswa ngaphambili, imvamisa yokudlidliza yokuxhumana nomlawuli ihamba kancane, kukhona inertia yemishini kanye ne-electromagnetic inertia, ukunemba kokulawulwa kwamandla kagesi kuphansi, ukuthintana kulula ukukhiqiza izinhlansi, ukuphazamiseka okukhulu komsakazo, ukwethembeka okubi, impilo emfushane, manje sekukhona. kuqedwe.

2. Umlawuli we-Transistor

Ngokuthuthukiswa kobuchwepheshe be-semiconductor, isilawuli se-transistor siyamukelwa.Izinzuzo imvamisa yokushintsha okuphezulu kwe-triode, azikho izinhlansi, ukunemba okuphezulu kokulungiswa, isisindo esincane, ivolumu encane, impilo ende, ukuthembeka okuphezulu, ukuphazamiseka okuncane komsakazo nokunye.Manje isetshenziswa kabanzi kumodeli yemoto yebanga eliphakathi neliphansi.

3. Isilawuli se-IC (Isilawuli sesekethe esihlanganisiwe)

Ngaphezu kwezinzuzo zomlawuli we-transistor, isilawuli sesifunda esihlanganisiwe sinobukhulu obuncane kakhulu futhi sifakwe ngaphakathi kwejeneretha (eyaziwa nangokuthi isilawuli esakhelwe ngaphakathi), esinciphisa izintambo zangaphandle futhi sithuthukise umphumela wokupholisa.Manje isisetshenziswa kakhulu eSantana, Audi nakwezinye izinhlobo zezimoto.

4. Isilawuli esilawulwa yikhompyutha

Ngemuva kokuthi ingqikithi yomthwalo wesistimu ikalwe ngomtshina wokulayisha ugesi, isignali ithunyelwa kukhompyutha ekhiqiza ijeneretha, bese isilawuli se-voltage ye-generator silawulwa yikhompyutha yenjini, bese kuthi isekethe ye-magnetic field ivulwe futhi ivalwe ngesikhathi esifanele. ngendlela, ngaleyo ndlela iqinisekise ngokuthembekile ukusebenza okuvamile kwesistimu kagesi, ibhethri ishajwe ngokugcwele, futhi inganciphisa umthamo wenjini futhi ithuthukise ukonga kukaphethiloli.Izilawuli ezinjalo zisetshenziswa kumajeneretha ezimoto afana neShanghai Buick neGuangzhou Honda.

Ulwazi olungenhla luwumgomo wokusebenza wesilawuli sikagesi kusethi yejeneretha.Kuyingxenye ebalulekile ye ukukhiqiza isethi .Amajeneretha Amandla e-Dingbo afakwe i-AVR.Uma unentshisekelo, sicela usithinte nge-imeyili dingbo@dieselgeneratortech.com, sizokuqondisa ukuthi ukhethe i-genset ekufanele kakhulu.
