IS200EHPAG1ABB GE EXCITER GATE PULSE AMPLIFIER BOARD
Lub is200ehpag1a yog ib feem ntawm ex2100 series. Qhov kev txiav txim ntawm pulse amplifier yog tswj ncaj qha rau silicon tswj rectifier (scr).
Cov plug connectors no txawv ntawm lawv xaiv thiab tus lej. 8 ntawm lawv yog ob npaug, 4 yog 4 thiab 2 yog 6. Lub connector yog nyob rau sab xis sab xis ntawm lub rooj tsav xwm Circuit Court nyob ze ntawm plaub qhov sawv thiab tuaj yeem siv los ua vaj huam sib luag.
Lub hwj chim hloov dua siab tshiab txee muaj lub hwj chim hloov dua siab tshiab module (PCM), lub rooj tsav xwm excitation pulse amplifier (EGPA), AC Circuit Court breaker thiab DC contactor. Peb-theem fais fab mov rau PCM los ntawm PPT sab nraum lub exciter. Lub zog AC nkag mus rau hauv lub txee los ntawm AC Circuit Court breaker (yog tias siv hluav taws xob) thiab raug lim los ntawm peb-theem kab lim hauv cov khoom pabcuam.
Kev tuav fais fab Disconnect (yeem)
Phau ntawv cua Circuit Court breaker disconnect hloov yog ib tug disconnect ntaus ntawv ntawm lub mov voltage transformer theem nrab thiab lub static exciter. Nws yog cov ntaub ntawv molded, peb-theem, tsis siv neeg, vaj huam sib luag mounted hloov uas yog manually ua los cais cov AC input zog. Nws yog ib tug tsis-load disconnect ntaus ntawv.
Fais fab Hloov Module (PCM)
Lub exciter PCM suav nrog tus choj rectifier, DC ceg fuses, thyristor tiv thaiv circuits (xws li, dampers, lim, thiab fuses), thiab ceg reactor Cheebtsam. Nyob ntawm qhov xav tau lub zog tso zis, cov khoom sib txawv yuav sib txawv rau qhov sib txawv ntawm tus choj ntsuas.
Choj Rectifiers
Txhua tus choj rectifier yog 3-theem puv-yoj thyristor choj, raws li qhia hauv daim duab 2-3, muaj 6 SCRs (thyristors) tswj los ntawm Excitation Gate Pulse Amplifier board (EGPA). Thaum tshav kub kub yog dissipated los ntawm loj aluminium kub dab dej thiab yuam airflow los ntawm overhead kiv cua.
Leg Reactors thiab Cell Snubbers
Commutating reactors nyob hauv AC ob txhais ceg muab SCRs, thiab cov dampers yog RC circuits los ntawm anode mus rau cathode ntawm txhua SCR. Cov dampers ntawm tes, kab-rau-kab dampers, thiab kab reactors ua cov haujlwm hauv qab no ua ke los tiv thaiv kev ua haujlwm yuam kev ntawm SCRs.
-Txhais tus nqi ntawm kev hloov pauv tam sim no los ntawm SCRs thiab muab qhov kev sib tw tam sim no los pab pib ua haujlwm.
-Txhim tus nqi ntawm qhov hloov pauv ntawm cov cell thiab txwv qhov rov qab voltage uas tshwm sim ntawm cov hlwb thaum lub sijhawm hloov pauv ntawm tes.
SCR ntes suav nrog PRV resistors los txwv qhov siab tshaj qhov rov qab voltage. Cov resistors tuaj yeem raug tshem tawm yog tias tsim nyog
Peb-theem input zog yog pub los ntawm theem nrab ntawm PPT mus rau tus choj rectifier, ncaj qha los yog los ntawm AC Circuit Court breaker los yog disconnect hloov thiab kab-rau-kab lim. Nrog rau tus choj rectifier inverting, tus choj rectifier muaj peev xwm siv tau qhov tsis zoo voltage, muab cov lus teb ceev ceev rau kev tsis lees paub thiab de-excitation. DC tam sim no cov zis ntawm tus choj rectifier yog pub los ntawm shunt thiab, nyob rau hauv ib co qauv, los ntawm ib tug contactor (41A los yog 41A thiab 41B) mus rau hauv lub generator teb. Choj rectifier tsim siv DC ceg fuses los tiv thaiv SCRs los ntawm overcurrent.
