2. Tsarin Gine-gine da Matsayin Aiki
IS200TPROH1C tana taka rawar sigina da cibiyar rarrabawa a cikin tsarin gine-ginen kariyar. Gabaɗayan tsarin kariyar gaggawa da farko ya ƙunshi sassa uku:
IS200TPROH1C Hukumar Tasha: Mai alhakin karɓar duk danyen siginar kariya daga firikwensin filin.
Kwamitocin Kariya na VPRO Sau uku-Riple (VPRO-R8, VPRO-S8, VPRO-T8): Karɓa sigina daga IS200TPROH1C, aiwatar da dabarun kariya da kai (misali, ƙayyadaddun ƙayyadaddun saurin gudu, duban aiki tare), da umarnin tafiyar fitarwa.
TREx Trip Relay Boards (misali, TREG): Karɓi umarni daga VPRO kuma kai tsaye sarrafa da'irar wutar lantarki na solenoids na tafiya.
Babban aikin IS200TPROH1C shine samar da siginonin shigarwa iri ɗaya, keɓance ga dukkan allunan VPRO guda uku a lokaci guda. Wannan yana nufin cewa kowace sigina, daga masu ɗaukar sauri zuwa na'urorin wutan lantarki da thermocouples, suna daidaitawa da rarraba ta TPRO zuwa tashoshi na VPRO masu zaman kansu guda uku.

Bugu da ƙari, tubalan tasha a kan TPRO nau'in ƙira ne na shinge kuma ana iya cire su gaba ɗaya daga allon, yana sauƙaƙe kulawa da aikin wayoyi.
3. Cikakken Ayyuka da Ka'idodin Aiki
3.1 Ayyukan Kariya na Gaggawa
Wannan shine mafi mahimmancin aikin IS200TPROH1C. Ka'idarsa ita ce saka idanu gudun turbin da haifar da kashewar gaggawa lokacin da saurin ya wuce madaidaicin madaidaicin.
Sayen sigina: An ƙera allon tashar tashar IS200TPROH1C don haɗa har zuwa tara masu ɗaukar saurin maganadisu. Wadannan tara tara yawanci ana kasu kashi biyu: rukuni ɗaya (na uku na farko) suna ba da babban mai kula don sarrafa saurin gudu da kariya ta farko; ɗayan rukunin (na gaba uku ko fiye) an sadaukar da su ga IS200TPROH1C don kariyar gaggawar gaggawa. TPRO yana ba da siginar sigina daga waɗannan na'urori masu saurin gaggawa na gaggawa zuwa allunan VPRO guda uku ta hanyar igiyoyi daban-daban da masu haɗawa, tare da kowane VPRO yana karɓar sigina daga ɗauka ɗaya.
Sarrafa sigina da watsawa:
Magnetic pickups suna jin haƙoran gear, suna haifar da siginar wutar lantarki na sinusoidal. Girman sigina da mitar suna ƙaruwa tare da haɓakar gudu.
Na'urar shigar da bayanai akan hukumar IS200TPROH1C tana aiwatar da waɗannan sigina masu girma. Da'irar shigarwar sa yana da takamaiman halaye na kaya kuma yana alfahari da kewayon ƙimar bugun bugun jini da babban hankali.
Za a iya samun abubuwan da za a ɗauka har zuwa mita 300 daga ma'aikatar IS200TPROH1C ta amfani da kebul mai murɗaɗɗen garkuwa, yana ba da kariya mai ƙarfi.
Maƙasudin Ragewa: Allolin VPRO guda uku suna ƙididdige saurin gudu bisa kan siginar da suka karɓa. Umurnin balaguron gaggawa yawanci yana amfani da dabaru na zaɓe 'biyu-daga-uku'; wato, tsarin zai fara tafiya ne kawai idan aƙalla VPRO guda biyu a lokaci guda sun gano yanayin da ya wuce kima. Wannan yana hana duka tafiye-tafiye na karya saboda ɗauka ɗaya ko gazawar VPRO da gazawar tafiya saboda kuskuren tashar guda ɗaya.
3.2 Ajiyayyen Aiki tare da Duba Ayyukan Kariya
Wannan aikin yana hana mai fasa janareta rufewa lokacin da janareta da grid ba su daidaita ba, ta haka ne ke nisantar babban lalacewar injina da na lantarki ga janareta da grid.
Sayen sigina: IS200TPROH1C tana karɓar sigina daga ɓangaren na biyu na masu taswira masu ƙarfi guda biyu: Voltage na Generator da Voltage Bus. Waɗannan sigina yawanci ana ƙididdige su a 115 V RMS.
Rarraba Sigina da Warewa: TPRO na ciki yayi daidai da waɗannan siginonin ƙarfin lantarki guda biyu kuma yana rarraba su zuwa allunan VPRO guda uku. Kowane shigarwar PT tana keɓanta da maganadisu a cikin TPRO, yana nuna shingen warewar 1500 V RMS, kuma kowane shigarwar PT yana gabatar da nauyin ƙasa da 3 VA, yana tabbatar da daidaito da aminci.
Ƙa'idar Aiki: Kowane kwamiti na VPRO yana ƙunshe da babban madaidaicin daidaita-check module wanda ke ci gaba da lura da bambancin girman ƙarfin lantarki, bambancin mita, da bambancin kusurwa tsakanin janareta da ƙarfin bas.
Fitar Kariya: Ana ba da siginar izini ne kawai lokacin da aka tabbatar da sharuɗɗan 'daidaitacce' daga tashoshin VPRO guda uku ta hanyar dabaru na zaɓe. Wannan yana tafiyar da gudun ba da sanda na K25A akan allon TREG. Lambobin sadarwar K25A suna da waya a jeri tare da babban haɗin kai-izinin gudu da lambobi ta atomatik. Wannan haɗin yanar gizo mai ƙarfi yana samar da ingantacciyar ma'amala ta aminci: za a iya ba da umarnin kusa da janareta idan sync-check na madadin, babban tsarin daidaitawa, da sauran izini duk an ba da su, yadda ya kamata ke hana umarnin rufewar karya.
3.3 Thermocouple da Ayyukan shigar da Analog
IS200TPROH1C kuma yana ba da ƙarin tashoshi na shigar da kariya ta analog don injin turbin gas, da farko ana amfani da shi don madadin zafin jiki da kariyar siga.
Abubuwan shigar da Thermocouple: IS200TPROH1C tana ba da abubuwan shigar da wutar lantarki guda 9, da farko ana amfani da su don kariya daga zafin jiki akan injin turbin gas. Wadannan 9 thermocouples ana rarraba su a ko'ina zuwa allon VPRO guda uku, tare da kowane VPRO yana karɓar 3. Wannan rarraba yana ba da damar sakewa: koda kuwa aikin ma'aunin zafin jiki na tashar VPRO daya ya kasa gaba daya, sauran tashoshi biyu na iya yin kariya daga zafin jiki.
Analog Inputs: IS200TPROH1C tana ba da abubuwan shigar analog guda 3:
1 Multi-aikin shigarwa: Mai daidaitawa ta hanyar masu tsalle JP1A da JP1B don karɓar siginar 4-20 mA na yanzu, ± 5 V DC, ko ± 10 V DC siginar wutar lantarki.
2 sadaukar da 4-20mA abubuwan shigarwa na yanzu.
Ana iya amfani da waɗannan abubuwan shigar na analog don saka idanu masu mahimmanci kamar matsa lamba mai lube ko matsin iskar gas, yin aiki azaman kariya ta ajiya ga babban tsarin sarrafawa. Allolin VPRO suna ba da wutar lantarki 28 V DC don waɗannan firikwensin. Ana daidaita wannan ƙarfin ta hanyar da'irori akan TPRO kafin a aika daidaitattun sigina na 4-20mA zuwa VPRO guda uku.
4. Hardware Design and Installation
IS200TPROH1C itace tasha tasha allo mai girman 17.8 cm Fadi x 33.02 cm High, wanda aka ƙera don hawa kai tsaye zuwa ƙarfen panel, yawanci ta amfani da tsarin hawan maɓalli.
Tubalan Tasha: Tubalan tasha a kan allo an raba su a fili zuwa wurare masu aiki, gami da Generator/Bas Voltage, Inputs Analog, Thermocouple Inputs, da Abubuwan shigar da Saurin Magnetic. Kowane tasha zai iya karɓar har zuwa wayoyi biyu na AWG #12 tare da rufin 300-volt.
Kulawa: Za a iya cire tubalan nau'in shinge gaba ɗaya daga allon kewayawa, wanda ya dace sosai don maye gurbin waya ko dubawa ba tare da sarrafa allon kanta ba.
Masu haɗawa: Ana samun haɗin kai zuwa allunan VPRO guda uku ta hanyar haɗin haɗin 37-pin 'D' -harsashi, waɗanda ke fasalta hanyoyin latching don ingantaccen haɗin gwiwa a cikin mahallin girgiza.
Iko: Allolin VPRO suna ba da wutar lantarki 28 V DC zuwa TPRO, musamman ana amfani da su don kunna na'urori masu auna firikwensin analog.
5. Bincike da Kulawa
Tsarin IS200TPROH1C da VPRO sun haɗa da cikakken bincike kan layi don tabbatar da lafiyar tsarin kariya.
Gano Sigina: VPROs suna ci gaba da lura da duk siginar shigarwa daga TPRO. Idan shigarwar analog ɗin ya wuce saiti mai girma/ƙananan iyakoki, ko kuma idan ingancin siginar ba ta da kyau, VPRO zai haifar da kuskure.
Hardware Identification da Compatibility Diagnostics: Masu haɗin kan tashar tashar ta TPRO sun haɗa guntu mai karantawa kawai. Wannan guntu yana da lamba tare da lambar serial na hukumar tasha, nau'in allo, lambar bita, da wurin filogi. Lokacin da hukumar VPRO ta yi ƙarfi ko aiki, tana karanta wannan bayanin ID. Idan aka gano rashin daidaituwa, nan da nan VPRO ya haifar da kuskuren 'hardware incompatibility', yana hana rashin daidaituwar aikin kariya wanda ya haifar da kuskuren tsarin hardware.
Takaitacciyar ƙararrawa: Idan kowane sigina daga TPRO ko igiyoyin haɗin kai an gano shi azaman mara lafiya, ana kunna ƙararrawar ganowa ta VPRO daidai. Ana iya kulle waɗannan sigina na bincike daban-daban kuma a sake saita su da zarar siginar ta dawo lafiya.
