FUNCTIONAL DESCRIPTION:

IS200EGDMH1AFG iExciter Ground Detector Module yakagadzirwa uye yakagadzirwa neGeneral Electric sechikamu cheEX2100 Series inoshandiswa muGE Excitation Control Systems. Iyo IS200EGDMH1 Ground Detection Module inoshandiswa muEX2100 Excitation Control. Iyo yakapetwa kaviri, yakapetwa kureba (6U) fomu factor bhodhi inokwira muExciter Power Backplane rack (EPBP). Munda wepasi detector inoona munda wekudonhedza-zera kuramba pakati pechero poindi mujenareta redunhu remumunda kusvika pasi, kungave kudivi reac kana dc. A simplex system ichange iine EGDM imwe chete, uye redundant system ichava nematatu. Nzvimbo yeEGDM (s) inoratidzwa muMufananidzo 1. EXAM, iyo attenuator module, inonzwa mhepo pamhepo inopikisa pasi uye inotumira chiratidzo kune EGDM (s) pamusoro pepfumbamwe-conductor cable. Iyo EXAM module yakaiswa muHigh Voltage Module iri muAixiliary Panel.

Mukudzora kusingadzoreki, seti yemabhodhi matatu eEGDM inogadziriswa seMutongi (C), Master 1 (M1), uye Master 2 (M2). Kugadziriswa kweEGDM yega yega inodzorwa neseti yemapini epurogiramu paP2 connector. Mashoko pamusoro pekuti tenzi anopa chiratidzo chekufambisa kune pfungwa inopikisa muAttenuator Module inotumirwa kubva kuDSPX, kuburikidza neEISB mune rack controller, kune EGDM C. Paakagamuchira ruzivo urwu pamusoro pe fiber-optic link, C inogona kupa simba relay muAttenuator Module kana M2 ari mutyairi, kana kuti anosiya asina simba kana M1 ari tenzi akasarudzwa. Panguva imwecheteyo, chiratidzo chekusiyanisa chinotumirwa kuM1 neM2 chinoratidza tenzi akasarudzwa. Ichi chiratidzo chinogonesa jenareta pane anoshanda tenzi uye anosarudza bvunzo yekuraira sosi pane yega module (M1, M2, uye C). Iye zvino tenzi anoshanda anogamuchira Oscillator Signal pamusoro peiyo fiber optic link kubva kuDSPX kuburikidza neEISB iyo inoshandura kuita yakanaka kana yakaipa 50-volt chiratidzo. Iyi square wave voltage inotumirwa netambo kune iyo EXAM module uye inoshandiswa kune imwe mugumo weSense Resistor.

Iyo yechiratidzo conditioner inogamuchira yakaderedzwa (10: 1) chiratidzo chekusiyanisa kubva kuSense Resistor mune EXAM module. Iyo sigineti conditioner iri nyore kubatana kuwana mutsauko amplifier ine yakakwira yakajairika-modhi yekuramba reshiyo inoteverwa neA-to-D inoshandura (Voltage Controlled Oscillator VCO). VCO inopa fiber optic transmitter. Iyo sign conditioner circuitry inofambiswa neiyo yakasarudzika magetsi kuchengetedza vashandi uye kuchengetedzwa kwemidziyo nekuda kweiyo yakakwira yakajairika-modhi voltage paSense Resistor. Iyo siginecha conditioner inogona kuyera iyo simba amplifier yekubuda nhanho nekudzika bhiriji padivi reattenuated Sense Resistor pakuraira kubva kuchikamu chekutonga.

ZVINHU:

• Chikamu cheC chemutongi chinogashira ese ehurongwa uye kudzora masaini kubva kwakasiyana masosi kuti aone kuti ndeipi module ichave tenzi. Iyo zvakare inogamuchira iyo oscillator chiratidzo kubva kuDSPX kuitira kuti igone kuburitsa bvunzo yekuraira pane imwe neimwe shanduko yeiyo oscillator chiratidzo.

• Muyedzo wekuraira ndeye 250 ms kureba siginecha inogona kudzoserwa pane yega shanduko yeiyo oscillator chiratidzo (kunyangwe kana nguva yechiratidzo isingasviki 250 ms).

• Uyu murairo webvunzo unozotumirwa kuchikamu chekutonga chemodule yega yega (M1, M2, uye C) kugadzira 250 ms refu chiratidzo chekuyedza pane yega yega shanduko yakanaka yemirairo yebvunzo. Ichi chiratidzo hachidzokerike uye saka shanduko dzinofanirwa kupatsanurwa neinopfuura 250 ms isati yagadzirwa imwe chiratidzo chekuyedza.

• Chikamu chekugovera magetsi chinogamuchira 24 V dc kubva kuEPSM yakakodzera kuburikidza neEPBP (backplane). Ichishandisa dc kune dc converter, inoshandura iyi kuita ± 65 V dc (isina-yakasarudzika) yemagetsi amplifier muchikamu chejenareta chechiratidzo, uye +5 V dc (yakasarudzika) uye ± 15 V dc (yakasarudzika) yechiratidzo chekugadzirisa.

• Iyo simba amplifier inobuda ndeye voltage sosi ine inobuda impedance isingasviki 1.0 Ohm. Mhepo inobuda ndeye ± 50 Volt squarewave ine ikozvino inogumira kusvika ku80 mA, uye ine yakajairwa nguva yekushandisa yemasekonzi mashanu. Panguva yekushanda kwekuedza, nguva yacho inoderedza kusvika ku400 ms.
