GE IS220PPRAH1A Pākuʻi Turbine Backup Protection I/O Module
ʻO ka IS220PPRAH1A kahi pahu I/O Emergency Turbine Protection (PPRA) a me TREA Terminal Board e hāʻawi ana i kahi ʻōnaehana pale kūʻokoʻa overspeed. Aia i loko o ka ʻōnaehana pale ʻekolu mau ʻeke Triple Modular Redundant PPRA I/O i kau ʻia ma ka TREA Terminal Board, me ka papa koho WREA. ʻO ka PPRA kahi mea i loaʻa i ka pahu maʻamau Mark VIe PPRO Emergency Turbine Protection I/O pack. ʻO ka hapa nui o ka hoʻonohonoho, nā ʻano a me nā ʻano o ka PPRA e like me ka PPRO. He kiko'ī ka PPRA i ka TREA Terminal Board i lako me ka papa koho WREA. Piʻi pololei ka PPRA ma luna o ka TREA, a i ka wā e hoʻohana ai i ka TREA, pono e kau ʻia ka papa koho WREA ma ka PPRA i hoʻolaʻa ʻia i ka poʻomanaʻo poʻo. E holo pono ana ka PPRA a me WREA i kau ʻia ma TREA ke hoʻohana ʻia ʻekolu pāpaʻi PPRA I/O.
ʻO nā nīnau i nīnau pinepine ʻia e pili ana i ka huahana penei:
-He aha ke kumu o ka module IS220PPRAH1A?
He modula I/O ka hoʻopaʻa ʻana i ka turbine pilikia i hoʻolālā ʻia e hāʻawi i ka pale pale no nā turbine.
-He aha nā ʻōnaehana i kūpono me ka IS220PPRAH1A?
Hoʻohui maikaʻi ʻia me nā mea ʻē aʻe Mark VI e hāʻawi i ka pale turbine piha.
-He aha nā hana nui o ka IS220PPRAH1A?
Hāʻawi i ka redundancy no nā ʻōnaehana pale mua. E hōʻoia i ka nānā ʻana a me ka pane ʻana i ka manawa maoli. ʻO ka module i kūkulu ʻia a me ka ʻōnaehana olakino hiki ke diagnostic.
