SHARAXA SHAQEEYA:

IS200EGDMH1AFG waa Exciter Ground Detector Module oo ay soo saartay oo ay naqshadaysay General Electric taas oo qayb ka ah Taxanaha EX2100 ee loo isticmaalo Nidaamyada Xakamaynta Dhiirigelinta GE. IS200EGDMH1 Module Detection Ground waxaa lagu isticmaalaa Xakamaynta Xakamaynta EX2100. Waa boos labajibbaaran, dherer labanlaab ah (6U) qaabka looxa qaabaysan kaas oo ku dul koraya rackka dambe ee Exciter Power Backplane (EPBP). Baaraha dhul-beereedka waxa uu ogaadaa iska caabbinta da'da daadinta goobta inta u dhaxaysa meel kasta oo ka mid ah wareegga beerta koronto-dhaliyaha ee dhulka, ha ahaato dhinaca ac ama dc. Nidaamka simplex wuxuu lahaan doonaa hal EGDM, iyo nidaamka aan caadiga ahayn wuxuu yeelan doonaa saddex. Goobta EGDM(-yada) waxa lagu muujiyay Jaantuska 1. EXAM, moduleka attenuator, waxa uu dareemaa danabka guud ahaan iska caabinta dareenka dhulka oo u diraya calaamada EGDM(-yada) korka xadhig sagaal-conductor ah. Module EXAM waxa lagu rakibay Module Voltage High oo ku yaala Gudida Kaaliyaha.

Xakamaynta aan badnayn, saddexda loox ee EGDM waxaa loo habeeyey sidii Controller (C), Master 1 (M1), iyo Master 2 (M2). Qaabaynta EGDM kasta waxa gacanta ku haya biinanka barmaamijka ah ee isku xidhka P2. Macluumaadka ku saabsan sayidku bixiyo signalka drive in resistor dareenka ee Module Attenuator waxaa laga soo diray DSPX ah, iyada oo loo sii marayo EISB ee rack kontoroolka, si EGDM C. Marka la helo macluumaadka this ka badan xidhiidhka fiber-optic, C midkood awood u gudbinta ee Module Attenuator ah haddii M2 waa darawalka, ama ka tago iyada oo aan la awoodin haddii M1 waa sayidkii la doortay. Isla mar ahaantaana, calaamad ka duwan ayaa loo diraa M1 iyo M2 taas oo muujinaysa sayidkii la doortay. Digniintu waxay awood u siinaysaa koronto-dhaliyaha calaamadaha sayidkaaga firfircoon oo doorta isha amarka tijaabada ee cutub kasta (M1, M2, iyo C). Hadda sayidkii firfircooni wuxuu ka helayaa ishaarka Oscillator ee isku xirka fiber optic-ga ee DSPX iyada oo loo sii marayo EISB taasoo u beddeleysa calaamad 50-volt togan ama taban. Danabkan mowjad labajibbaaran ayaa fiilo loo diraa moduleka EXAM waxaana lagu dabaqaa hal daraf oo ka mid ah iska caabinta Dareenka.

Qaboojiyaha calaamaduhu wuxuu helayaa calaamad la dhimay (10:1) oo ka duwan dareenka iska caabbinta ee qaybta EXAM. Qaboojiyaha calaamaduhu waa cod-weyneeye ka duwan faa'iido midnimo fudud oo leh saamiga diidmada qaab-cameed sare oo ay ku xigto beddelaha A-to-D (Voltage Controlled Oscillator VCO). VCO waxay quudisaa gudbiyaha fiber optic-ga. Wareegga kondeeyaha signalka waxa ku shaqeeya sahay koronto oo go'doonsan si loo ilaaliyo badbaadada shaqaalaha iyo qalabka taas oo ay ugu wacan tahay korantada-habka caadiga ah ee sare ee Dareemaha iska caabinta. Qaboojiyaha calaamaduhu waxa uu cabbiri karaa heerka soo saarida cod-weyneeye-koronta isaga oo dhulka dhigaya dhinaca buundada ee iska caabbinta Dareenka la yareeyey ee amarka qaybta kantaroolka.

MEESHA:

• Qaybta C ee maamuluhu waxay helaysaa dhammaan barnaamijyada iyo calaamadaha xakamaynta ee ilaha kala duwan si loo go'aamiyo cutubka noqon doona sayidkiisa. Waxa kale oo ay ka heshaa signalka oscillator-ka DSPX si ay u soo saarto amar tijaabo ah mar kasta oo kala guurka ah ee signalka oscillator-ka.

• Amarka tijaabadu waa calaamad dheer oo 250 ms ah oo dib loo soo celin karo mar kasta oo kala-guurka signalka oscillatorka (xitaa haddii muddada calaamaduhu ka yar tahay 250 ms).

• Amarka tijaabada ayaa markaa loo diraa qaybta kantaroolka ee cutub kasta (M1, M2, iyo C) si ay u dhaliyaan calaamad tijaabo ah oo dhererkeedu yahay 250 ms meel kasta oo togan oo amarka tijaabada ah. Digniintu maaha mid dib loo soo celin karo, sidaas darteed kala-guurka waa in la kala saaraa in ka badan 250 ms ka hor inta aan la soo saarin calaamad kale oo tijaabo ah.

• Qaybta korontadu waxay ka helaysaa 24 V dc EPSM ku habboon iyada oo loo marayo EPBP (diyaaradaha dambe). Isticmaalka dc ilaa dc beddele, waxay tan u beddeshaa ± 65 V dc (aan go'doon ahayn) cod-weyneeye korantada qaybta koronto-dhaliyaha, iyo + 5 V dc (go'doon) iyo ± 15 V dc (go'doon) qaboojinta calaamadaha.

• Wax-soo-saarka korantadu waa il danab leh oo wax-soo-saarku uu ka yar yahay 1.0 Ohm. Korantada wax soo saarku waa ± 50 Volt mawjad laba jibaaran oo hadda xaddidan oo ku saabsan 80 mA, iyo muddada hawlgalka caadiga ah ee 5 ilbiriqsi. Inta lagu jiro hawlgalka tijaabada, wakhtiga ayaa hoos u dhacaya ilaa 400 ms.
