II. Babban Ayyuka
Babban ayyuka na IS200EACFG2A sun haɗa da, amma ba'a iyakance su ba, masu zuwa:
1. Exciter Voltage Aunawa
Hukumar IS200EACFG2A tana goyan bayan shigarwar wutar lantarki mai kashi uku na AC, musamman an ƙera shi don ƙarancin ƙarfin lantarki na 1000 V rms. Takamammen bayanansa sune kamar haka:
Rage Wutar Wutar Lantarki na Input: Har zuwa 1000 V rms
Ƙarfin Ƙarfafawa: + 20% (watau ci gaba mai dorewa shigarwar har zuwa 1200 V rms)
Matsakaicin Mitar: 50/60 Hz
Fitar da Wutar Lantarki: Mai iya Canjin Canjin Kan Jirgin (PPT) fitarwa na biyu shine 1.6 V rms.
Ana amfani da masu juyawa T1 zuwa T4 akan allo don jujjuya wutar lantarki mai matakai uku. Ana haɗa wutar lantarki ta shigarwa ta tashoshi masu zaman kansu guda uku: TB1, TB2, da TB3. An ƙera ma'aunin ma'aunin wutar lantarki daidai don samar da ingantattun siginonin martani na ƙarfin lantarki zuwa tsarin sarrafa kuzari don tsari, kariya, da dalilai na aiki tare.
2. Air Core CT/Flux Coil Inputs
Hukumar IS200EACFG2A tana ba da tashoshi biyu masu zaman kansu na Flux/Air Core shigar da tashoshi don auna sigina na yanzu ko juyi daga tsarin tashin hankali. Waɗannan sigina na shigarwa galibi sun samo asali ne daga Air Core Current Transformers (CTs) ko coils, tare da halayen fitarwa na yau da kullun:
Rage Wutar Wutar Lantarki na Ƙarfafa: 0 ~ 0.8 V rms (50/60 Hz)
Terminal Input: Terminal toshe TB4, yana ba da ƙungiyoyin shigarwa guda biyu (kowanne tare da manyan tashoshi da ƙananan)
Ana yin siginar shigar da siginar Air Core CT ga babban hayaniyar amo a wurin shiga hukumar don kawar da tasirin kutse a wurin kan daidaiton aunawa. Ana iya haɗa garkuwar igiyoyin shigarwar zuwa ƙasan chassis ta skru na ƙasa kusa don tabbatar da ingancin sigina.
3. Fitowar sigina da mu'amala
Hukumar IS200EACFG2A tana bin hanyoyin da aka auna ƙarfin lantarki da sigina na yanzu zuwa allunan EMIO na tsarin sarrafawa (ta hanyar EBKP backplane) ta hanyar haɗin Sub-D mai 9-pin uku (J504, J509, J514). Waɗannan masu haɗa guda uku sun dace da:
J504: Haɗa zuwa mai sarrafa M1
J509: Haɗa zuwa mai sarrafa M2
J514: Haɗa zuwa mai sarrafa C
Ayyukan fil na kowane mai haɗawa iri ɗaya ne, yana tabbatar da cewa siginonin da masu sarrafa guda uku suka karɓa sun yi daidai, suna biyan buƙatun tsarin kulawa da yawa.
4. Abubuwan Gwaji
Allon yana da zoben gwajin ƙarfin lantarki TP1 ta TP4 don auna matakan ƙarfin lantarki na lokaci-zuwa-lokaci daga masu iya canzawa:
Tsakanin TP1 da TP2: Auna Layin Voltage AB
Tsakanin TP3 da TP4: Auna Layin Voltage BC
Tsakanin TP4 da TP1: Auna Layin Voltage CA
Waɗannan wuraren gwaji suna sauƙaƙe ƙaddamarwa a kan wurin aiki da magance matsala, ba da damar masu fasaha su ɗauki ma'auni kai tsaye tare da multimeter ko oscilloscope ba tare da cire haɗin wayar waje ba.
III. Aikace-aikacen Tsarin
1. Aikace-aikace a cikin EX2100 Excitation Control System
IS200EACFG2A babban allo ne a cikin EX2100 Excitation Control System don samun siginar martani na AC daga mai jan hankali. Ayyukansa a cikin tsarin sun haɗa da:
Feedback Voltage: Yana auna ƙarfin wutar lantarki na AC mai kashi uku daga PPT mai ban sha'awa, yana ba da sigina na amsawar wutar lantarki zuwa Mai sarrafa Wutar Lantarki ta atomatik (AVR) don sarrafa madauki da tsarin wutar lantarki.
Feedback na Yanzu/Flux: Yana karɓar sigina daga Air Core CTs ko juzu'i mai jujjuyawa don saka idanu mai haɓaka halin yanzu ko yanayin juzu'i, samar da bayanai don kariyar tashin hankali da tsarin sa ido.
Rarraba Siginar Rarraba: Lokaci guda yana rarraba siginar da aka auna zuwa masu sarrafawa guda uku (M1, M2, C), saduwa da buƙatun sakewa na tsarin EX2100 da haɓaka amincin tsarin.
