Inkcazo

I-SPM-A Synchronizer biases isantya se-off-line generator iseti ukwenzela ukuba i-frequency kunye nesigaba sihambelane nezo zomnye umvelisi okanye ibhasi yomsebenzi. Emva koko ikhupha ngokuzenzekelayo isignali yokuvala uqhagamshelwano ukuvala i-breaker circuit phakathi kwezi zibini xa i-frequency kunye nesigaba zihambelana phakathi kwemida yexesha elichaziweyo lomdlalo. I-SPM-A yi-phase-locked-loop synchronizer kwaye ilwela umdlalo ogqibeleleyo wokuphindaphinda kunye nesigaba.

I-SPM-A Synchronizer ehambelana nombane yenza imiqondiso eyongezelelweyo yokunyuswa kunye nesezantsi (ukuvalwa konxibelelwano lwe-relay) kwisilawuli sombane wejenereyitha. Amandla ombane kufuneka ahambelane nokunyamezelana kweSPM-A phambi kokuba kuvalwe ibreaker. Ungqamaniso lweyunithi enye, ukufakelwa kwe-synchronizer enye kwijeneretha nganye ivumela iyunithi nganye ukuba ihambelane nebhasi. Kungqamaniso lweeyunithi ezininzi, isingqamanisi esinye sinokungqamanisa ukuya kutsho kwiiyunithi ezisixhenxe ezihambelanayo zejenereyitha ngaxeshanye kwenye ibhasi. Zombini iinguqulelo ze-synchronizers zineenketho ezintathu zokuphuma: i-impedance ephezulu, i-impedance ephantsi, kunye ne-EPG.

Khetha imveliso ye-impedance ephezulu yongqamaniso lweyunithi enye xa injini ilawulwa yi-Woodward 2301 yolawulo. Khetha imveliso ephantsi ye-impedance yongqamaniso lweyunithi enye xa i-injini ilawulwa yi-Woodward 2301A, 2500, okanye i-Electric Powered Governor (EPG) ngokulawula i-Generator Load Sensor. Sebenzisa imveliso ye-EPG xa usebenzisa ulawulo lwe-Woodward EPG ngaphandle kokuva umthwalo. Zombini ezi yunithi zinezi mpawu zilandelayo:

 120 okanye 208/240 igalelo leVac

 ifestile yesigaba se-10 degree

 I-1/8, 1/4, 1/2, okanye i-1 yexesha lokuhlala lesibini (ukutshintsha kwangaphakathi okukhethiweyo, i-factory isetelwe i-1/2 isekhondi) I-SPM-A Synchronizer ene-voltage ehambelanayo inomdlalo we-voltage we-1% njengomgangatho. Jonga itshathi yenxalenye yenombolo yolunye ukhetho.

Ithiyori yokuSebenza

Eli candelo lichaza ithiyori jikelele yokusebenza kweenguqulelo ezimbini ze-SPM-A Synchronizer. Umzobo 1-1 ubonisa i-SPM-A Synchronizer ehambelana nombane. Umzobo 1-2 ubonisa umzobo webhloko ye-synchronizer eqhelekileyo. Umzobo 1-3 ubonisa umzobo webhloko osebenzayo we-synchronizer.

Ungeniso lwe-synchronizer

I-SPM-A Synchronizer ihlola i-angle yesigaba kunye nokuphindaphinda kwebhasi kunye nejeneretha engaxhunyiwe kwi-intanethi ekufuneka ihambelane. Igalelo lamandla ombane elisuka kwibhasi kunye nejenereyitha liqale lisetyenziswe kwiisekethe zomguquli wophawu olwahlukileyo. Isilungisi ngasinye sophawu sisihluzo esitshintsha ubume beempawu zegalelo lombane ukuze zilinganiswe ngokuchanekileyo. I-potentiometer yesigaba sokunciphisa kwi-signal conditioner circuit ilungelelaniswa ukuhlawulela iimpazamo zesigaba. (Olu lungelelaniso lusetelwe kwi-factory kunye ne-bus efanayo kunye ne-generator inputs. Kufuneka ihlaziywe kuphela apho ukutshatyalaliswa kwesigaba kuye kwabangelwa ngabaguquli bomgca wofakelo.) I-conditioner yesignali iphinda ikhulise iimpawu zebhasi kunye nejeneretha kwaye zisebenzise kwisigaba. umtshini.

Iindlela zokuSebenza Iswitshi yemowudi efakwe ngumsebenzisi (ipali enye, indawo emine) ilawula umqhubi we-relay.

Iswitshi kufuneka ifakwe kwi-synchronizer zoqhagamshelwano 10 ukuya ku-13 (jonga umzobo wocingo lweplanti). Ezo zikhundla zine ZIVALIWE, BALEKA, KHANGELA, kwaye UVUMELE.
