Banyere nchebe mgbanaka nmikpu mmanụ, ntụaka sitere na ụlọ ọrụ mgbanwe China
N’ebe a, SPL, ụlọ ọrụ mgbanaka China, na-enye gị ntụaka maka nchebe ụgbọ njem na-emikpu mmanụ. Enwere ngwaọrụ nchekwa nchekwa 3:
1, gas ọsọ agba anọ: eji maka 800kVA na n’elu mmanụ-mikpuru transformer. Mgbe ike kọntaktị nke gas relay dị ukwuu karịa 66VA ma ọ bụ 15W na mkpokọta gas bụ 250 ~ 300ml ma ọ bụ n’ime nso nke edobere na mmanụ ọsọ, ekwesịrị ijikọ kọntaktị kwekọrọ. Ọdịdị na nrụnye ọnọdụ nke relay gas kwesịrị inwe ike ịhụ ọnụọgụ na agba nke gas, ọ dịkwa mfe iburu gas. Wụnye ya na mmụba 1.5% na gradient. 220kV transformer mmanụ tank cover kwesịkwara inwe 1 ~ 1.5% ụba mkpọda.
2, valve ntọhapụ nrụgide: ejiri maka 800kVA na ndị na-agbanwe agbanwe; Mgbe nrụgide dị na igbe mmanụ nke ụzọ nchekwa nchekwa ma ọ bụ valve enyemaka nrụgide ruru 5.07 × 104Pa, a ga-ahapụ ya nke ọma. Ekwesịrị ịtọ valve enyemaka nrụgide abụọ maka onye ntụgharị na 120000kVA na n’elu.
3, valvụ, ventilashị plọg: niile mgbidi tank tank kwesịrị kwadebere na mmanụ sample valve, 110kV, 90000kVA na 220kV, 63000kVA na n’elu n’etiti tank mgbidi kwesịrị nwekwara mmanụ sample valve. 315kVA na n’elu tankị ga-enwe ngwaọrụ igbapu na ala. Akụkụ ala nke tankị nke na-atụgharị kwesịrị ịbụ nnukwu valvụ mgbapụta mmanụ zuru oke, onye ntụgharị 220kV kwesịkwara inwe valvụ mgbapụta mmanụ ihe mberede. Onye ntụgharị ahụ ga-ebunye gas mgbe ọ na-ejuputa mmanụ na ule, ya mere, akụkụ elu nke pedestal transformer, radiator, bushing, wdg, nwere ihe nkwụnye ikuku iji hụ na nchekwa nke transformer.
