Chav Kawm 1E Hom Transformer Qhuav rau Cov Chaw Tsim Hluav Taws Xob Nuclear

1. Lub Transformer Hom Qhuav Class 1E yog dab tsi?

Ua ntej, nws yog ib qho tseem ceeb kom nkag siab txog lub ntsiab lus tseem ceeb ntawm "Chav Kawm 1E".

Chav Kawm 1E: Qhov no yog kev faib tawm kev nyab xeeb uas tau los ntawm cov qauv tsim hluav taws xob nuclear (piv txwv li, IEEE Std 323 hauv Tebchaws Meskas lossis GB/T 12727 hauv Suav teb). Nws hais txog cov khoom siv hluav taws xob thiab cov txheej txheem tseem ceeb rau kev ua cov haujlwm kev nyab xeeb tseem ceeb, xws li kev kaw lub reactor thaum muaj xwm txheej ceev, kev cais tawm, kev txias ntawm lub reactor, thiab kev tiv thaiv kev tso tawm cov khoom siv radioactive.

Hom Transformer Qhuav: Lub transformer uas nws cov windings tsis raug muab tso rau hauv cov roj rwb thaiv tsev tab sis raug tiv thaiv los ntawm cov khoom siv rwb thaiv tsev khov kho (piv txwv li, epoxy resin).

Yog li ntawd, Chav Kawm 1E Hom Transformer Qhuav yog txhais tias: Lub transformer qhuav-hom tsim tshwj xeeb los muab hluav taws xob rau cov kab ke kev nyab xeeb-chav kawm (1E) ntawm lub chaw tsim hluav taws xob nuclear. Nws yuav tsum muaj peev xwm ua haujlwm tau zoo thiab txuas ntxiv mus rau hauv cov xwm txheej ib txwm muaj, cov xwm txheej sib tsoo (piv txwv li, av qeeg, LOCA - Kev poob ntawm Coolant Accident), thiab cov chaw tom qab sib tsoo rau lub sijhawm teev tseg.

Hais yooj yim xwb, nws yog ib qho ntawm "cov chaw muab hluav taws xob cawm siav" rau lub tshuab hluav taws xob nuclear.

1. Vim li cas cov chaw tsim hluav taws xob nuclear yuav tsum siv cov Transformers Class 1E?

Kev nyab xeeb ntawm lub chaw tsim hluav taws xob nuclear yog qhov tseem ceeb tshaj plaws. Lub luag haujlwm ntawm Class 1E transformers yog los muab lub zog ruaj khov thiab txhim khu kev qha rau cov khoom siv kev nyab xeeb tseem ceeb hauv qab qhov xwm txheej hnyav tshaj plaws, suav nrog:

Cov txheej txheem faib khoom ntsig txog kev nyab xeeb

Cov khoom siv hloov pauv rau cov tshuab hluav taws xob diesel thaum muaj xwm txheej ceev

Cov txheej txheem tswj thiab tiv thaiv reactor

Cov Tsav Tsheb Rau Cov Twj Tso Kua Dej Kub Ceev (ECCS)

Cov txheej txheem saib xyuas tom qab muaj xwm txheej

Cov tshuab cua thiab kev cais tawm

Yog tias cov kab ke no tsis muaj zog lawm ces yuav ua rau muaj kev puas tsuaj loj heev. Yog li ntawd, cov tshuab hloov pauv Class 1E yog ib qho tseem ceeb hauv lub chaw tsim hluav taws xob nuclear txoj kev tiv thaiv tob tob.

1. Cov Kev Cai Tseem Ceeb & Cov Txuj Ci Tseem Ceeb rau Chav Kawm 1E Cov Transformers Qhuav

Cov transformers Class 1E txawv ntawm cov transformers qhuav uas siv rau hauv kev lag luam lossis kev lag luam. Lawv cov kev xav tau tseem ceeb yog raws li hauv qab no:

1. Kev Txhim Kho Zoo Tshaj Plaws & Kev Tsim Nyog Ib puag ncig (K1, K2, K3 Cov Khoom Siv)

Cov chaw tsim hluav taws xob nuclear faib cov khoom siv Class 1E raws li qhov hnyav ntawm cov xwm txheej ib puag ncig uas lawv yuav tsum tiv taus. Transformers poob rau hauv cov pawg sib xws:

Pawg K1: Nruab rau hauv qhov chaw kaw. Yuav tsum tiv taus cov xwm txheej ib txwm muaj, av qeeg (OBE/SSE), thiab qhov kub thiab txias, siab, av noo, thiab cov tshuaj tsuag uas tshwm sim los ntawm Kev Poob Dej Txias (LOCA), thiab yuav tsum ua haujlwm tau tom qab muaj xwm txheej. Qhov no yog pawg nruj tshaj plaws.

Qeb K2: Nruab rau hauv qhov chaw kaw tab sis tsuas yog yuav tsum tau tiv taus cov xwm txheej ib txwm muaj thiab av qeeg, tsis suav nrog LOCA ib puag ncig.

Qeb K3: Nruab rau sab nraum qhov chaw kaw tab sis yog ib feem ntawm lub kaw lus kev nyab xeeb, yuav tsum tau tiv taus cov xwm txheej ib txwm muaj thiab av qeeg.

Cov Txuj Ci Tseem Ceeb Sib Xws:

Lub Tshuab Rwb Thaiv Kub Tshwj Xeeb: Siv cov khoom siv rwb thaiv kub zoo, tiv taus hluav taws, tiv taus dej noo, thiab tiv taus hluav taws xob (piv txwv li, cov tshuaj epoxy zoo). Cov txheej txheem casting/impregnation siab heev (piv txwv li, thev naus laus zis rwb thaiv kub nyias, Lub Tshuab Nqus Pa Nqus Pa) siv los xyuas kom meej tias cov qauv rwb thaiv kub ntom tsis muaj qhov khoob, nrog rau cov qib tso tawm tsawg heev.

Kev Tiv Thaiv Hluav Taws Zoo Tshaj Plaws (F1 Chav Kawm): Cov ntaub ntawv tua nws tus kheej thiab yuav tsis ua kom kub hnyiab txawm tias raug hluav taws qhib, tiv thaiv hluav taws kub kis mus.

Lub Zog Kho Tshuab Ruaj Khoov: Tag nrho cov qauv transformer (xws li cov xov hlau, cov thav duab, thiab lwm yam) yuav tsum tiv taus qhov Kev Nyab Xeeb Kaw Av Qeeg (SSE) yam tsis muaj kev puas tsuaj, kom ntseeg tau tias muaj kev ua haujlwm zoo. Qhov no yuav tsum tau lees paub los ntawm kev tshuaj xyuas Finite Element Analysis (FEA) thiab kev sim ua kom muaj kev nyab xeeb ntawm av qeeg.

2. Kev Tswj Xyuas Zoo thiab Daim Ntawv Pov Thawj Zoo

Kev Pab Cuam QA Nuclear: Tag nrho lub neej—txij li kev tsim qauv, kev yuav khoom siv, kev tsim khoom, kev sim, mus txog rau kev xa khoom—yuav tsum ua raws li kev pab cuam kev lees paub zoo ntawm nuclear (feem ntau raws li HAF 003 lossis 10 CFR 50 Appendix B), kom ntseeg tau tias muaj kev tswj hwm tag nrho thiab kev taug qab tau.

Kev Tsim Nyog & Daim Ntawv Pov Thawj: Lub transformer yuav tsum dhau qhov kev xeem hom thiab kev xeem txog kev tiv thaiv av qeeg uas ua los ntawm lub koom haum uas tau lees paub los ntawm lub koom haum tswj kev nyab xeeb nuclear hauv tebchaws (piv txwv li, NNSA hauv Suav teb) los qhia tias ua raws li cov qauv Class 1E. Qhov no yog nws "daim ntawv tso cai" nkag mus rau hauv kev ua lag luam.

3. Kev Tsim Qauv thiab Kev Ntsuas Kev Ua Haujlwm Tshwj Xeeb

Kev Tiv Thaiv Kev Laus Hluav Taws Xob: Tshwj xeeb tshaj yog rau cov hloov pauv qeb K1, cov ntaub ntawv rwb thaiv tsev thiab cov khoom siv qauv yuav tsum tau soj ntsuam kom ntseeg tau tias tsis muaj kev puas tsuaj loj heev nyob rau hauv qhov xav tau ntawm cov hluav taws xob thoob plaws lawv lub neej.

Kev Ntsuas Ib Txwm & Hom: Dhau li ntawm cov kev ntsuas tus qauv (piv, kev tiv thaiv, tsis muaj-load / load poob, dielectric, suab nrov, thiab lwm yam), kev ntsuas tshwj xeeb yog qhov yuav tsum tau ua, xws li:

Kev Ntsuas Ib Nrab ntawm Kev Tso Tawm: Cov kev cai yog nruj heev, feem ntau xav tau cov theem qis dua 5-10 pC, kom ntseeg tau tias kev rwb thaiv tsev ruaj khov mus sij hawm ntev.

Kev Ntsuas Hluav Taws Xob Impulse (Xob laim & Hloov Impulse).
