GE IS200EXAMG1A Exciter Attenuation Module

IS200EXAMG1A Module ne na Ƙarfafawa na Exciter wanda General Electric (GE) ya tsara don EX2100 ™ da EX2100e ™ Tsarin Sarrafa Hankali. Wannan tsarin yana aiki tare da Exciter Ground Detector Module (EGDM) ko Hukumar Kula da Taimako (EAUX) don samar da cikakken tsarin gano ƙasa, wanda ake amfani da shi don lura da yanayin rufewa na kewaye filin janareta zuwa ƙasa. Tsarin IS200EXAMG1A an ɗora shi a cikin Module na Babban Wutar Lantarki (HVI) wanda ke cikin majalisar taimako. Babban aikinsa shi ne attenuate babban ƙarfin lantarki daga bas ɗin filin zuwa siginar ƙaramar sigina mai amfani don sarrafawa ta hanyar kewayawar ƙasa.

A cikin tsarin sarrafa tashin hankali na EX2100, IS200EXAMG1A yana haɗawa da Exciter Power Backplane (EPBP) ta hanyar kebul na 9-pin guda ɗaya, yayin da EGDM ya shiga cikin EPBP ta hanyar haɗin 96-pin, P2. EGDM tana sarrafa kunna gwaje-gwajen ƙasa da zaɓin babban mai sarrafa ta hanyar relay dake cikin EXAM. Lokacin da aka kunna gwajin ƙasa, ana rarraba wutar lantarki ta bas a kan masu adawa da attenuation da masu adawa da hankali. Gwajin na iya ɗaukar har zuwa daƙiƙa 10. Idan mataccen gajere zuwa ƙasa ya auku akan bas ɗin, duk ƙarfin wutar lantarkin bas ɗin zai bayyana a cikin sashe ɗaya na resistors na attenuation, kuma tsarin zai haifar da kuskure kuma ya rufe injin a cikin daƙiƙa 10.

A cikin tsarin sarrafawa na EX2100e, IS200EXAMG1A yana hulɗa tare da hukumar EAUX. EAUX yana ba da siginar raƙuman murabba'in ± 50 V zuwa EXAM kuma yana karɓar siginar martani na analog daidai da ƙasa na yanzu baya daga EXAM. EAUX yana ba da abubuwan fitar da direba guda biyu zuwa EXAM: ɗaya don zaɓar M1 ko M2 mai gano ƙasa mai yawa, ɗayan kuma don sarrafa relay na gwaji (wanda ke kan EXAM_B da na baya) wanda ke sanya juriya na ɗan lokaci don gwada aikin gano ƙasa.

Tsarin IS200EXAMG1A yana da ƙira mai sauƙi kuma abin dogaro ba tare da maki gwaji, fuses, ko alamun LED ba. Tsarin ya ƙunshi abubuwa masu zuwa:

• J2 Connector: 9-pin D-nau'in haɗin haɗin don siginar gwaji, sarrafawar relay, da ɗigogi na halin yanzu.

• J1 Connector: 3-pin kulle haši don kebul zuwa filin mai walƙiya relay lambar sadarwa.

• E1, E2 Stab-on Connectors: Haɗa ingantattun ƙarfin ƙarfin bas ɗin filin da mara kyau.

• Terminal TB1: Ma'anar haɗi don ƙasan garkuwar hukumar EXAM zuwa ƙasan chassis na majalisar.

• JP1, JP2, JP3 Jumpers: Ana amfani da su don saita tsarin don matakan ƙarfin lantarki na biyu na PPT daban-daban.
