Kufotokozera

SPM-A Synchronizer imakondera liwiro la jenereta yopanda pa intaneti kuti ma frequency ndi gawo zifanane ndi za jenereta ina kapena mabasi othandizira.Kenako imangotulutsa chizindikiro chotseka cholumikizira kuti mutseke chowotcha pakati pa ziwirizi pomwe ma frequency ndi gawo zimagwirizana mkati mwa malire anthawi yofananira.SPM-A ndi gawo-lokhoma-loop synchronizer ndipo imayesetsa kuti ifanane ndi ma frequency ndi gawo.

The SPM-A Synchronizer yokhala ndi ma voltage yofananira imapanga ma siginolo owonjezera okweza ndi otsika (kutsekeka kolumikizana ndi ma relay) kwa chowongolera magetsi cha jenereta.Magetsi ayenera kugwirizana mkati mwa kulolerana kwa SPM-A kusanatseke kosokoneza.Pa kulumikizana kwa unit imodzi, kukhazikitsa synchronizer imodzi pa jenereta iliyonse kumalola gawo lililonse kuti lifanane ndi basi.Kuti mulunzanitse mayunitsi ambiri, cholumikizira chimodzi chimatha kulunzanitsa mpaka mayunitsi asanu ndi awiri ofananira nthawi imodzi ndi basi ina.Mitundu yonse ya ma synchronizers ali ndi njira zitatu zotulutsa: high impedance, low impedance, ndi EPG.

Sankhani kutulutsa kwamphamvu kwapang'onopang'ono kwa kulumikizana kwa unit imodzi pamene injini imayendetsedwa ndi Woodward 2301 control.Sankhani zotulutsa zocheperako pakulumikizana kwa unit imodzi pomwe injini ikuwongoleredwa ndi Woodward 2301A, 2500, kapena kuwongolera kwa Magetsi a Governor (EPG) kudzera pa Jenereta Load Sensor.Gwiritsani ntchito kutulutsa kwa EPG mukamagwiritsa ntchito Woodward EPG control popanda kumva katundu.Mayunitsi onsewa ali ndi izi:

 120 kapena 208/240 Vac input

 10 digiri gawo zenera

 1/8, 1/4, 1/2, kapena 1 sekondi yokhala nthawi (kusintha kwamkati kosankhidwa, fakitale yokhazikitsidwa kwa 1/2 sekondi) Synchronizer ya SPM-A yokhala ndi ma voteji imakhala ndi 1% machesi amagetsi monga muyezo.Onani tchati cha nambala kuti musankhe zina.

Chiphunzitso cha Ntchito

Gawoli likufotokoza za kagwiritsidwe ntchito ka mitundu iwiri ya SPM-A Synchronizer.Chithunzi 1-1 chikuwonetsa SPM-A Synchronizer yokhala ndi ma voliyumu ofanana.Chithunzi 1-2 chikuwonetsa chojambula chofananira cha synchronizer system block.Chithunzi 1-3 chikuwonetsa chojambula chogwira ntchito cha synchronizer.

Zolowetsa za Synchronizer

SPM-A Synchronizer imayang'ana mbali ya gawo ndi mafupipafupi a basi ndi jenereta yopanda mzere yomwe iyenera kufananizidwa.Ma voliyumu a mabasi ndi jenereta amayikidwa koyamba kuti asiyanitse ma frequency owongolera ma siginecha.Chizindikiro chilichonse chimakhala ndi fyuluta yomwe imasintha mawonekedwe a ma voliyumu olowetsamo kuti athe kuyeza bwino.Gawo lochepetsera potentiometer mu gawo lowongolera ma signal limasinthidwa kuti libwezere zolakwika za gawo.(Kusintha uku kumayikidwa ndi fakitale yokhala ndi zolowetsa za basi ndi jenereta zofanana. Ziyenera kusinthidwa kokha pamene gawo lochepetsera layambika kudzera muzitsulo zosinthira mzere wa kuyika.) Zowonetsera zizindikiro zimakulitsanso zizindikiro za basi ndi jenereta ndikuziyika pagawo. chodziwira.

Mayendedwe Ogwiritsira Ntchito Siwichi yoyika wogwiritsa ntchito (ndondomeko imodzi, malo anayi) imayang'anira dalaivala wotumizirana mauthenga.

Chosinthiracho chiyenera kukhala ndi mawaya olumikizirana 10 mpaka 13 (onani chithunzi cha mawaya).Maudindo anayi ndi OFF, RUN, CHECK, ndi PERMISSIVE.
