IS200EHPAG1ABB GE EXCITER GATE PULSE AMPLIFIER BOARD
The is200ehpag1a ndi gawo la mndandanda wa ex2100. Chochita cha pulse amplifier ndikuwongolera mwachindunji silicon controlled rectifier (scr).
Zolumikizira zamapulagizi zimasiyana pakusankha kwawo komanso nambala. 8 mwa iwo ndi awiri, 4 ndi 4 ndi 2 ndi 6. Cholumikiziracho chili pakona yakumanja kwa bolodi la dera pafupi ndi maimidwe anayi ndipo angagwiritsidwe ntchito ngati chowonjezera chamagulu.
Kabati yosinthira mphamvu imakhala ndi gawo losinthira mphamvu (PCM), bolodi yothamangitsa chipata cha pulse amplifier (EGPA), AC circuit breaker ndi DC contactor. Mphamvu ya magawo atatu ku PCM imachokera ku PPT kunja kwa exciter. Mphamvu ya AC imalowa mu nduna kudzera pa AC circuit breaker (ngati ipatsidwa mphamvu) ndipo imasefedwa ndi mzere wa magawo atatu mu nduna yothandizira.
Lumikizani Mphamvu Pamanja (Mwasankha)
Chosinthira chowongolera mpweya chowongolera ndi chipangizo cholumikizira pakati pa thiransifoma yamagetsi yachiwiri ndi static exciter. Ndi chiwongolero chopangidwa, chamagulu atatu, chopanda chodziwikiratu, chokhazikika chomwe chimagwiritsidwa ntchito pamanja kuti chizipatula mphamvu yolowera ya AC. Ndi chipangizo chopanda kulumikiza.
Power Conversion Module (PCM)
PCM yosangalatsa imaphatikizapo chowongolera mlatho, ma fuse a DC mwendo, mabwalo achitetezo a thyristor (mwachitsanzo, ma dampers, zosefera, ndi ma fuse), ndi zigawo za reactor. Kutengera ndi mphamvu zomwe zimafunikira, zigawozo zimasiyana mosiyanasiyana pamilatho.
Bridge Rectifiers
Chiwongolero chilichonse cha mlatho ndi mlatho wa 3-phase full-wave thyristor, monga momwe zasonyezedwera pa Chithunzi 2-3, chokhala ndi 6 SCRs (thyristors) yoyendetsedwa ndi gulu la Excitation Gate Pulse Amplifier board (EGPA). Kutentha kumatayidwa ndi masinki akuluakulu otentha a aluminiyamu ndi kutuluka kwa mpweya wokakamiza kuchokera ku mafani apamwamba.
Zopangira Miyendo ndi Zopangira Ma cell
Ma reactors osinthira amakhala mumiyendo ya AC yopereka ma SCRs, ndipo ma dampers ndi mabwalo a RC kuchokera ku anode kupita ku cathode ya SCR iliyonse. Ma cell dampers, ma line-to-line dampers, ndi ma reactors a mzere amagwira ntchito zotsatirazi palimodzi kuti ateteze ntchito yolakwika ya SCRs.
-Kuchepetsa kuchuluka kwa kusintha kwapano kudzera mu SCRs ndikupereka njira yomwe ilipo kuti ithandizire kuyambitsa kuyendetsa.
- Chepetsani kuchuluka kwa ma voliyumu pakati pa ma cell ndikuchepetsa mphamvu yamagetsi yomwe imachitika pakati pa ma cell panthawi yakusintha kwa ma cell.
Zomangira za SCR zikuphatikiza ma PRV resistors kuti achepetse nsonga yamagetsi. Zotsutsa izi zitha kuchotsedwa ngati kuli kofunikira
Mphamvu yolowera ya magawo atatu imadyetsedwa kuchokera ku sekondale ya PPT kupita ku rectifier ya mlatho, mwachindunji kapena kudzera pa AC circuit breaker kapena disconnect switch and line-to-line filters. Ndi kamangidwe ka inverting bridge rectifier, chowongolera mlatho chimatha kuyika voteji yoyipa, kupereka kuyankha mwachangu pakukana katundu ndi kutulutsa chisangalalo. Kutulutsa kwaposachedwa kwa DC kwa mlatho wokonzanso mlatho kumadyetsedwa kudzera pa shunt ndipo, m'mapangidwe ena, kudzera pa cholumikizira (41A kapena 41A ndi 41B) kulowa mugawo la jenereta. Mapangidwe okonzanso mlatho amagwiritsa ntchito ma fuse a miyendo ya DC kuteteza ma SCR kuti asapitirire.
