Klas 1E Igwe Transformer Akọrọ maka Osisi Ike Nuklia

1. Kedu ihe bụ Class 1E Dry-Type Transformer?

Nke mbụ, ọ dị mkpa ịghọta isi echiche nke "Klas 1E".

Klas nke 1E: Nke a bụ nhazi nchekwa sitere na ọkọlọtọ imewe ụlọ ọrụ ike nuklia (dịka ọmụmaatụ, IEEE Std 323 na US ma ọ bụ GB/T 12727 na China). Ọ na-ezo aka na ngwa eletriki na sistemụ dị mkpa maka ịrụ ọrụ nchekwa dị mkpa, dịka mmechi mberede reactor, ichekwa ihe nchekwa, oyi isi reactor, na mgbochi mwepụta ihe redioaktivu.

Transformer Ụdị Akọrọ: Transformer nke eriri ya anaghị abanye n'ime mmanụ mkpuchi mana ihe mkpuchi siri ike (dịka ọmụmaatụ, resin epoxy) na-echebe.

Ya mere, a na-akọwa Transformer nke Klas 1E Dry-Type dị ka: Transformer nke a kpọrọ nkụ nke e mere kpọmkwem iji nye ike na sistemụ nchekwa (1E) nke ụlọ ọrụ ike nuklia. Ọ ghaghị inwe ike ịrụ ọrụ nke ọma ma na-aga n'ihu n'okpuru ọnọdụ nkịtị, ọnọdụ ihe mberede (dịka ọmụmaatụ, ala ọma jijiji, LOCA - Mfu nke Ihe Mberede Coolant), na gburugburu ebe ihe mberede gasịrị ruo oge akọwapụtara.

N'ikwu ya n'ụzọ dị mfe, ọ bụ otu n'ime "isi iyi ike ndụ" maka sistemụ nchekwa nke ụlọ ọrụ ike nuklia.

1. Gịnị mere ụlọ ọrụ ike nuklia ji kwesị iji Transformers Klas 1E?

Nchekwa ụlọ ọrụ ike nuklia bụ ihe kachasị mkpa. Ọrụ nke transformers Klas 1E bụ inye ike kwụsiri ike na nke a pụrụ ịtụkwasị obi nye akụrụngwa nchekwa dị mkpa n'okpuru ọnọdụ kachasị njọ, gụnyere:

Sistemụ nkesa metụtara nchekwa

Switchgear maka ihe nrụpụta dizel mberede

Sistemụ njikwa na nchekwa nke ihe mmeghachi omume

Moto maka mgbapụta Sistemụ Mberede Isi Oyi (ECCS)

Sistemụ nlekota mgbe ihe mberede gasịrị

Sistemụ ikuku na mwepụ nkewa

Mfu nke ike na sistemụ ndị a nwere ike ibute nnukwu ihe egwu. Ya mere, transformers Klas 1E bụ ihe dị mkpa na atụmatụ nchekwa miri emi nke ụlọ ọrụ ike nuklia.

1. Ihe Ndị Dị Mkpa na Teknụzụ Dị Mkpa Maka Transformers Klas 1E Akọrọ

Transformers Klas 1E dị iche nke ukwuu na transformers ụlọ ọrụ ma ọ bụ nke azụmahịa. Ihe ha chọrọ bụ isi n'ebe ndị a:

1. Ntụkwasị Obi na Asambodo Gburugburu Ebe Obibi Kachasị Elu (Ngwa K1, K2, K3)

Ụlọ ọrụ ike nuklia na-ekewa akụrụngwa Klas 1E dabere na oke ọnọdụ gburugburu ebe obibi ha ga-eguzogide. Transformers na-adaba n'ụdị ndị kwekọrọ:

Ụdị K1: E tinyere ya n'ime ebe a na-echekwa ihe. Ọ ghaghị iguzogide ọnọdụ nkịtị, ala ọma jijiji (OBE/SSE), na okpomọkụ dị elu, nrụgide dị elu, oke iru mmiri, na gburugburu ebe a na-agba mmiri kemịkalụ sitere na Mfu nke Ihe Mberede Coolant (LOCA), ma ga-anọgide na-arụ ọrụ mgbe ihe mberede ahụ gasịrị. Nke a bụ ụdị kachasị sie ike.

K2 Category: E tinyere ya n'ime ebe a na-echekwa ihe mana ọ dị mkpa ka ọ ghara ịdaba n'ọnọdụ nkịtị na ala ọma jijiji, ewezuga gburugburu ebe obibi LOCA.

K3 Category: E tinyere ya n'èzí ebe a na-echekwa ihe mana ọ bụ akụkụ nke sistemụ nchekwa, nke achọrọ iji nagide ọnọdụ nkịtị na ala ọma jijiji.

Teknụzụ Ndị Dị Mkpa:

Sistemụ Mkpuchi Pụrụ Iche: A na-eji ihe mkpuchi dị elu, nke na-egbochi ire ọkụ, nke na-eguzogide mmiri, na nke na-eguzogide radieshon (dịka ọmụmaatụ, resin epoxy dị elu). A na-eji usoro nhazi/mkpuchi dị elu (dịka ọmụmaatụ, teknụzụ mkpuchi dị gịrịgịrị, Mkpuchi Nrụgide Vacuum) iji hụ na ihe owuwu mkpuchi dị oke njọ enweghị oghere, yana ọkwa mwepụ akụkụ dị ala.

Ike Na-eguzogide Ọkụ Kachasị Elu (Klas F1): Ihe ndị a na-emenyụ onwe ha ma ha agaghị anọgide na-ere ọkụ ọbụlagodi mgbe e tinyere ha n'ọkụ mepere emepe, na-egbochi mgbasa ọkụ.

Ike Mekaniki Siri Ike: Nhazi transformer dum (gụnyere windings, fremu, wdg) ga-eguzogide Safe Shutdown Ala Ọma Jijiji (SSE) na-enweghị mmebi, na-ahụ na arụmọrụ ya ziri ezi. A ghaghị ịkwado nke a site na Nyocha Ihe Ndị Dị Mkpa (FEA) na nnwale asambodo ala ọma jijiji siri ike.

2. Nkwenye na Asambodo Ogo siri ike

Mmemme QA nuklia: Usoro ndụ dum—site na imewe, ịzụta ihe, nrụpụta, nnwale, ruo na nnyefe—ga-agbaso usoro nkwenye mma nuklia (nke dabere na HAF 003 ma ọ bụ 10 CFR 50 Mgbakwunye B), na-ahụ na njikwa na nchụso usoro zuru oke.

Asambodo na Asambodo: Transformer ahụ ga-agafe ule ụdị na ule asambodo ala ọma jijiji nke ụlọ ọrụ nke ndị na-ahụ maka nchekwa nuklia mba ahụ (dịka ọmụmaatụ, NNSA na China) kwadoro mere iji gosi na ha na-agbaso ụkpụrụ Klas 1E. Nke a bụ "ikikere" ya ịbanye n'ahịa.

3. Nhazi na Nnwale Arụmọrụ Pụrụ Iche

Nguzogide Radiation Aging: Karịsịa maka transformers nke K1, a ga-enyocha ihe mkpuchi na akụkụ nhazi iji hụ na enweghị mmebi arụmọrụ dị ukwuu n'okpuru dose radieshon a tụrụ anya ya n'oge ndụ ha niile.

Usoro na Ule Ụdị siri ike: Karịa ule ọkọlọtọ (oke, nguzogide, enweghị ibu/mfu ibu, dielectric, ọkwa ụda, wdg), ule pụrụ iche bụ iwu, dịka:

Ntụle nke Mwepụ Akụkụ: Ihe achọrọ siri ike nke ukwuu, nke na-achọkarị ọkwa dị n'okpuru 5-10 pC, iji hụ na a pụrụ ịtụkwasị mkpuchi ogologo oge.
