Mkpuchi larịị nke transformer

Dị ka ngwa eletriki dị mkpa na usoro ọkụ ọkụ, ọkwa mkpuchi nke ihe ngbanwe na-ejikọta ya na ọrụ nchekwa ma kwụsie ike nke usoro ike. Ọkwa mkpuchi bụ ikike nke onye na-agbanwe agbanwe na-eguzogide oke dị iche iche na oke ọkụ na-arụ ọrụ ogologo oge n'oge a na-arụ ọrụ, ma bụrụ isi ihe na-enweghị ike ileghara anya na nhazi, nrụpụta, ịrụ ọrụ na mmezi nke ihe ntụgharị.

1. Nkọwa nke ọkwa mkpuchi nke transformer ọkwa mkpuchi na-ezo aka n'ikike nke ihe mkpuchi mkpuchi nke transformer iji nọgide na-eguzosi ike n'ezi ihe na nchekwa mgbe ọ na-eguzogide oke dị iche iche na voltaji na-arụ ọrụ ogologo oge. Nke a gụnyere ọkwa voltaji nke enwere ike ịnabata ya na njide ọkụ na-echebe ma dabere na oke voltaji Um nke akụrụngwa.

2. Ihe mkpuchi mkpuchi nke transformer Dị ka ma ọkwa mkpuchi nke njedebe nke eriri ikuku na ebe na-anọpụ iche bụ otu ihe ahụ, enwere ike kewaa onye ntụgharị ahụ n'ime ihe mkpuchi abụọ: mkpuchi zuru oke na mkpuchi akara. Ihe ngbanwe nke nwere ihe mkpuchi mkpuchi zuru oke nwere otu ihe mkpuchi mkpuchi nke njedebe nke ikuku ikuku na ebe na-anọpụ iche, nwere oke mkpuchi dị elu, ọ dịkwa mma maka ndị na-agbanwe agbanwe nwere ọkwa voltaji dị elu na gburugburu ọrụ mgbagwoju anya. Ihe ngbanwe nke nwere ihe mkpuchi nke nwere akara ngosi na-edobe ọkwa mkpuchi dị iche iche n'etiti ngwụcha ahịrị winding na ebe na-anọpụ iche dabere na mkpa n'ezie iji bulie ihe mkpuchi mkpuchi ma belata ọnụ ahịa.

3. Nnwale nke mkpuchi mkpuchi nke onye na-agbanwe agbanwe Iji hụ na ọkwa mkpuchi nke onye na-agbanwe agbanwe na-emezu ihe ndị a chọrọ, a chọrọ usoro nyocha nke mkpuchi. Maka ndị ntụgharị nwere ọkwa voltaji nke 220kV na n'okpuru, a na-eme ugboro ugboro ike nkeji 1 na-anagide ule voltaji yana nnwale voltaji na-akpali akpali iji chọpụta ike mkpuchi ha. Maka ndị ntụgharị nwere ọkwa voltaji dị elu, a na-achọkwa nnwale mkpali dị mgbagwoju anya. N'ule ụlọ ọrụ mmepụta ihe, a na-eme ule na-eguzogide voltaji na ihe karịrị okpukpu abụọ nke voltaji a kwadoro n'otu oge iji nyochaa arụmọrụ mkpuchi nke isi mkpuchi na mkpuchi ogologo.

Tụkwasị na nke ahụ, ịlele nguzogide mkpuchi, absorption ratio na polarization index nke winding yana oke ohia bụkwa ụzọ dị mkpa iji nyochaa ọnọdụ mkpuchi n'ozuzu nke transformer. Ntụle ndị a nwere ike ịchọpụta nke ọma oke mmiri nke mkpuchi ihe ngbanwe, mmiri ma ọ bụ unyi dị n'elu ihe ndị ahụ, yana ntụpọ etinyere na ntinye.

4. Ihe ndị na-emetụta ọkwa mkpuchi nke onye na-agbanwe agbanwe N'oge a na-arụ ọrụ nke onye na-agbanwe agbanwe, ihe ndị na-emetụta ọkwa mkpuchi na-agụnye okpomọkụ, iru mmiri, usoro nchebe mmanụ na mmetụta overvoltage. 1) Okpomọkụ: Okpomọkụ bụ isi ihe na-emetụta arụmọrụ mkpuchi nke transformer. Ọrụ mkpuchi nke ihe mkpuchi na-ebelata na mmụba nke okpomọkụ, na ọnụnọ nke mmiri na mmanụ ga-eme ka ịka nká nke mkpuchi ahụ dịkwuo elu. Ya mere, ịchịkwa okpomọkụ na-arụ ọrụ nke transformer na ịnọgide na-enwe ọnọdụ dị mma nke ihe mkpuchi bụ ihe dị mkpa iji melite ọkwa mkpuchi.

2) iru mmiri: Ọnụnọ nke iru mmiri ga-eme ka ịka nká nke ihe mkpuchi ahụ dịkwuo elu ma belata ọrụ mkpuchi ya. Ya mere, n'oge ọrụ nke transformer, ambient iru mmiri kwesịrị ịchịkwa nke ọma iji gbochie ihe mkpuchi ahụ ka ọ ghara ịdị mmiri.

3) Usoro nchebe mmanụ: Ụzọ nchebe mmanụ dị iche iche nwere mmetụta dị iche iche na arụmọrụ mkpuchi. Ebe ọ bụ na a na-ekpuchi elu mmanụ nke ihe ngbanwe ahụ mechiri emechi site na ikuku, ọ nwere ike igbochi nkwụsịtụ na mgbasa nke CO na CO2 na mmanụ, si otú ahụ na-ejigide ọrụ dị mma nke mmanụ mkpuchi.

4) Mmetụta overvoltage: Mmetụta overvoltage bụ ihe ọzọ dị mkpa na-emetụta ọkwa mkpuchi nke ihe ntụgharị. Ma ọkụ ọkụ na oke ọkụ na-arụ ọrụ nwere ike imebi ihe mkpuchi mkpuchi nke ihe ngbanwe. Ya mere, mgbe ị na-emepụta ma na-arụ ọrụ nke transformer, mmetụta nke overvoltage ga-atụle n'ụzọ zuru ezu na a ga-emerịrị usoro nchebe kwekọrọ.
