Otu esi ahọrọ nha nke sistemụ nchekwa mmanụ transformer

Okwu Mmalite;

N'ọrụ transformer ọkara na elu voltaji, sistemụ nchekwa mmanụ dị oke mkpa maka nchekwa gburugburu ebe obibi, nrubeisi iwu, na nchekwa ọrụ. Na JZP, anyị bụ ọkachamara n'ịmepụta ngwọta nchekwa siri ike nke dabara na mkpa pụrụ iche nke transformers ụlọ ọrụ mmepụta ihe na nke ọrụ. Nduzi a na-akọwapụta ihe ndị dị mkpa na usoro maka ikpebi nha kacha mma nke sistemụ nchekwa mmanụ transformer, na-ahụ na ha dabara na ụkpụrụ mba ụwa na ihe achọrọ maka ọrụ kpọmkwem.

Ihe Ndị Dị Mkpa Na-emetụta Nhazi Sistemụ Nchekwa;

 

Olu Mmanụ Transformer;

 

Isi Ụkpụrụ: Sistemụ njide kwesịrị ịnabata 100% nke ikike mmanụ kachasị ukwuu nke transformern'ọnọdụ nkịtị na 110% n'oge ọnọdụ ọkụ(gụnyere mmiri ọkụ na mmiri ozuzo)

 

Ngụkọta Ihe Nlereanya:

 

Transformer 110 kV nke nwere ikike mmanụ tọn 30 (≈34 m³) chọrọ olu nchekwa nke 37.4 m³(34 m³ × 1.1) iji mezuo ụkpụrụ nchekwa ọkụ.

 

Ntụaka Iwu:

 

GB50060-2008iwu ka e nwee sistemụ nchekwa maka Transformer dị n'èzís nwere ikike mmanụ ≥1,000 kg ga-ejidePasent 60 nke olu tankị kachasị ukwuuọ bụrụ na emejuputa nkewa mmanụ na mmiri.

 

Ọnọdụ Ebe A Kpọmkwem;

 

 

Ntinye ime ụlọ na mpụga:

 

Transformers dị n'ime ụlọ (dịka ọmụmaatụ, n'ime obere ọdụ ụgbọ ala) na-achọkarị obere njide n'ihi gburugburu ebe a na-achịkwa, ebe sistemụ dị n'èzí ga-akọwa maka mmiri ozuzo na ikuku na-abanye.

 

Nkwụsị Nchekwa Ọkụ:

 

Nọgide na-enwe opekempe anya mita 1.5n'etiti transformers na mgbidi ndị nwere ike ire ere, na 1 mita gafere nsọtụ transformermaka mgbasa mmiri ọkụ

 

Ihe Ndị Dị na Geotechnical na Gburugburu Ebe Obibi;

 

Ike Ibu Ala: Nyochaa ụdị ala (dịka ọmụmaatụ, ụrọ, ajịrịja) iji chọpụta nkwụsi ike ntọala na ihe achọrọ maka mmiri ozuzo

 

Oke Mmiri ozuzo: Maka sistemụ dị n'èzí, gbakọọ onyinye mmiri ozuzo site na iji data ihu igwe mpaghara (dịka ọmụmaatụ, 100 mm/hr maka mpaghara okpomọkụ).

 

 

Usoro nhazi nzọụkwụ site na nzọụkwụ;

 

Chọpụta Oke Mmanụ Kachasị Elu;

 

Nyochaa eserese teknụzụ nke transformer iji chọpụta oke mmanụ kachasị (dịka ọmụmaatụ, lita 10,000 maka nkeji 60 MVA).

 

Tinye ihe achọrọ n'iwu;

 

Nrubeisi SPCCMaka nrụnye ndị dị na US, soro iwu 110% nke EPA (olu mmanụ + 10% freeboard)

 

Ụkpụrụ ndị China:

 

GB50053-2013: Ọ chọrọ nchekwa 20% maka transformers dị n'ime ụlọ nwere mmanụ ≥100 kg, nke na-abawanye ruo 100% ma ọ bụrụ na mmiri anaghị arụ ọrụ.

 

Gbakọọ Olu Nchekwa;

 

Usoro:

 

Namkpokọta​=(Nammanụ​×1.1)+(Nammiri × 0.35)

 

V_mmiri: Olu mmiri ọkụ (mpaghara elu × ọnụego mmiri × oge).

 

0.35: Akụkụ efu nke ihe e ji ajịrịja jupụta (40% porosity)

 

Nhazi maka ọtụtụ ihe mgbanwe;

 

 

Gbakọọ oke mmanụ maka transformers a chịkọtara ma tinye 20% nke enweghị ike ịgbasa n'ọdịnihu.

Simenti E Siri Ike: A na-ahọrọ ya maka ngwa ime ụlọ n'ihi iguzogide ọkụ na ịdịte aka.

 

Ihe mkpuchi geomembrane: Jiri ihe mkpuchi HDPE mee ihe n'èzí iji gbochie mmiri ịbanye n'ime ala

 

Nkọwapụta nke Akara Nkịtị;

 

Ọkpụrụkpụ: ≥250 mm.

 

Nha nkume: Dayameta 50–80 mm maka porosity kacha mma na mbelata ọkụ
