Transformer yeClass 1E Dry-Type yeNyukireya Power Plants

1. Chii chinonzi Class 1E Dry-Type Transformer?

Chekutanga, zvakakosha kunzwisisa pfungwa huru ye "Kirasi 1E".

Kirasi 1E: Uku kupatsanurwa kwekuchengetedzwa kunobva pamatanho ekugadzira zvivakwa zvemagetsi enyukireya (semuenzaniso, IEEE Std 323 muUS kana GB/T 12727 muChina). Zvinoreva zvishandiso zvemagetsi nemasisitimu akakosha pakuita mabasa akakosha ekuchengetedza, akadai sekuvharwa kwechimbichimbi kwereactor, kupatsanurwa kwecontainment, kutonhora kwereactor core, uye kudzivirira kuburitswa kwezvinhu zvine mwaranzi.

Transformer yemhando yakaoma: Transformer ine mawindings asina kunyudzwa mumafuta ekudzivirira asi anodzivirirwa nezvinhu zvakasimba zvinodzivirira kupisa (semuenzaniso, epoxy resin).

Saka, Transformer yeClass 1E Dry-Type inotsanangurwa se: Transformer yemhando yakaoma yakagadzirirwa kupa simba kumasisitimu emhando yekuchengetedza (1E) echigadzirwa chemagetsi enyukireya. Inofanira kukwanisa kushanda zvakavimbika uye nguva dzose mumamiriro ezvinhu akajairwa, mamiriro enjodzi (semuenzaniso, kudengenyeka kwenyika, LOCA - Kurasikirwa neAccident yeCooler), uye nzvimbo dzepashure petsaona kwenguva yakatarwa.

Zvichitaurwa zviri nyore, ndeimwe ye "nzvimbo dzinobatsira zvikuru" kuchengetedza michina yemagetsi enyukireya.

1. Sei Zvivako zveMasimba eNyukireya Zvichifanira Kushandisa MaTransformer eClass 1E?

Kuchengetedzeka kwezviteshi zvemagetsi enyukireya ndiko kunonyanya kukosheswa. Basa rematransformer eClass 1E nderekupa simba rakasimba uye rakavimbika kumidziyo yekuchengetedza yakakosha mumamiriro ezvinhu akaipisisa, anosanganisira:

Masisitimu ekugovera ane chekuita nekuchengetedzeka

Switchgiya yemajenareta edhiziri ekukurumidzira

Masisitimu ekudzora nekudzivirira reactor

Mota dzemapombi eEmergency Core Cooling System (ECCS)

Masisitimu ekutarisa mushure metsaona

Masisitimu ekudzivirira mhepo uye ekuzviparadzanisa

Kurasikirwa nesimba kune aya masisitimu kunogona kukonzera migumisiro yakaipa. Saka, ma transformer eClass 1E chinhu chakakosha muhurongwa hwakadzama hwekudzivirira simba renyukireya.

1. Zvinodiwa Zvikuru & Matekinoroji Akakosha eMatransformer eClass 1E Dry-Type

Matransformer eClass 1E akasiyana zvikuru nematransformer emhando ye "dry-type" akajairwa eindasitiri kana ebhizinesi. Zvinodiwa zvikuru zvinoonekwa munzvimbo dzinotevera:

1. Kuvimbika Kwekupedzisira & Kufanirwa Kwezvakatipoteredza (K1, K2, K3 Equipment)

Zvivako zvemagetsi enyukireya zvinoisa michina yeClass 1E mumapoka zvichienderana nekuoma kwemamiriro ekunze azvinofanira kutsungirira. Matransformer anowira muzvikamu zvinoenderana:

Rudzi rweK1: Rwakaiswa mukati memuchina. Runofanira kutsungirira mamiriro ezvinhu akajairwa, kudengenyeka kwenyika (OBE/SSE), uye tembiricha yakakwira, kumanikidzwa kwakakwira, hunyoro hwakawanda, uye makemikari anopfapfaidza anokonzerwa neKurasikirwa neAccident yeCooliant (LOCA), uye runofanira kuramba ruchishanda mushure metsaona. Iri ndiro boka rakanyanya kuomarara.

Rudzi rweK2: Yakaiswa mukati memuchina wekuchengetedza mvura asi inongodiwa chete kuti ikwanise kutsungirira mamiriro ezvinhu akajairwa uye kudengenyeka kwenyika, kunze kwenzvimbo yeLOCA.

K3 Rudzi: Yakaiswa kunze kwemuchina wekuchengetedza asi chikamu chehurongwa hwakabatana nekuchengetedzeka, hunodiwa kuti hurambe hwakajairwa uye kudengenyeka kwenyika.

Matekinoroji Akakosha Anoenderana:

Sisitimu Yekudzivirira Yakakosha: Inoshandisa zvinhu zvekudzivirira zvinodzivirira moto, zvinodzivirira hunyoro, uye zvinodzivirira mwaranzi (semuenzaniso, resin yepamusoro-soro ye epoxy). Maitiro epamusoro ekukanda/kuisa mvura (semuenzaniso, tekinoroji yekudzivirira yakatetepa, Vacuum Pressure Impregnation) anoshandiswa kuona kuti chimiro chekudzivirira chakakora chisina maburi, chine huwandu hwakaderera hwekuburitsa mvura.

Kudzivirira Murazvo Mukuru (F1 Class): Zvinhu zvinozvidzima zvega uye hazvizorambi zvichibvira kunyangwe zvikaiswa murazvo wakashama, zvichidzivirira kupararira kwemoto.

Simba Remuchina Rakasimba: Chimiro chose chetransformer (kusanganisira mawindings, mafuremu, nezvimwewo) chinofanira kutsungirira Kudengenyeka Kwepasi Kwakachengeteka (SSE) pasina kukuvara, zvichiita kuti mashandiro acho ave akasimba. Izvi zvinofanirwa kusimbiswa kuburikidza neFinite Element Analysis chaiyo (FEA) uye kuyedzwa kwakasimba kwekuyedzwa kwepasi.

2. Kuvimbiswa Kwemhando Yakasimba & Chitupa

Chirongwa cheNyukireya QA: Kutenderera kwehupenyu hwese—kubva pakugadzira, kutenga zvinhu, kugadzira, kuyedza, kusvika pakuendesa—kunofanirwa kutevedzera chirongwa chekusimbisa hunhu hwenyukireya (chinowanzo shandiswa paHAF 003 kana 10 CFR 50 Appendix B), zvichiita kuti maitiro acho aonekwe uye aonekwe zvakanaka.

Zvikwaniriso & Chitupa: Transformer inofanira kupasa bvunzo dzemhando yepamusoro uye bvunzo dzezvikwaniriso zvekudengenyeka kwenyika dzinoitwa nesangano rinozivikanwa nesangano renyika rinoona nezvekuchengetedzwa kwenyukireya (semuenzaniso, NNSA muChina) kuratidza kutevedzera mitemo yeClass 1E. Iri ndiro "rezinesi" rayo rekupinda mumusika.

3. Kugadzira & Kuedza Kwakanangana Nekushanda

Kuramba Kukwegura Nemwaranzi: Kunyanya kune ma transformer emhando yeK1, zvinhu zvinodzivirira kupisa uye zvikamu zvemuumbi zvinofanirwa kuongororwa kuti zvive nechokwadi chekuti hapana kuora kwakakosha kwekushanda pasi pehuwandu hwemwaranzi hunotarisirwa muhupenyu hwavo hwese.

Miedzo Yakaoma Yemaitiro & Mhando: Kunze kwemiedzo yakajairwa (chiyero, kuramba, kurasikirwa nemutoro/mutoro, dielectric, nhanho yeruzha, nezvimwewo), miedzo yakakosha inofanirwa kuitwa, yakaita se:

Kuyerwa Kwekubuda Kwemvura Zvishoma: Zvinodiwa zvakanyanya kuomarara, zvinowanzoda mazinga ari pasi pe5-10 pC, kuti ive nechokwadi chekuti insulation inogara kwenguva refu.

Kuedzwa kweMagetsi eKuvhundutsa (Mheni & Kuchinja Magetsi).
