1.1 Nkọwa oru ngo

Emepụtara maka onye ahịa South Africa na 2024, ụdị nkesa nkesa 2100 kVA akọrọ na-egosipụta windings nke etinyere nke ọma na resin epoxy. N'ịbụ mmanụ na-efu -, ọ na-ebelata ohere nke ọkụ na mmetọ gburugburu ebe obibi. Site na mkpuchi klaasị F akwadoro maka okpomọkụ na-arụ ọrụ ruo ogo 155.

A na-atụle ihe ngbanwe ahụ na 2100 kVA, yana voltaji bụ isi nke 13.8 kV na voltaji nke abụọ nke 0.468 kV (468 V). Ọ dị mma maka ịgbanye igwe mgbọ m na ngwa nhazi dị arọ nke na-arụ ọrụ na 468 V.

Otu vector ya bụ D (+15 ogo )d0, ebe akụkụ dị elu{2}} voltaji na-egosipụta mgbanwe usoro ogo +15. Nhazi a na-egbo mkpa usoro usoro ma na-enyere aka belata harmonics na ikesa mmiri n'oge arụ ọrụ yiri ya.

A na-eme isi ya bụ silicon steel nke nwere ọka, nke na-enye mfu dị ala yana njupụta magnetik dị elu, na-enye aka na mfu enweghị obere{{0} nke 3.2 kW.

Ejiri onye na-ahụ maka okpomọkụ na ihe ntụgharị dị ugbu a (5000/1 CT), onye na-agbanwe agbanwe na-akwado nlekota ikuku na nchedo ikuku, yana nha nke ugbu a, na-eme ka ntinye aka na nchebe na usoro nlekota oru.

2.1 Isi

Ihe nkesa 2100 kVA atọ - nkesa ụdị nkụgharị ihe nkesa isi na-eji ọka{2}} na-eji mpempe akwụkwọ nchara silicon nke nwere nnukwu ike ndọta, na-eme ka arụmọrụ elektrọnịk dịkwuo mma yana ibelata mfu ndị bụ isi. Ibé akwụkwọ ndị a nwere ihe arụrụ arụ siri ike iji nagide nhazi yana nrụgide ogologo oge{{4}. SCOTECH na-eme ka ọ bụrụ ihe na-erughị ma ọ bụ nhata 0.02mm na enweghị ntụpọ. A na-eji mmiri kpuchie isi isi okwu - resin epoxy na-egosi maka ịdịte aka yana nchebe iru mmiri.

2.2 Ikuku

Ụdị ihe ngbanwe akọrọ akọrọ na-egosipụta windings abụọ, nke ejiri ndị na-eduzi aluminum na-adịgide adịgide rụọ ya iji hụ na arụmọrụ dị mma na ogologo ndụ ọrụ. A na-eji ihe mkpuchi klaasị F kpuchie ikuku niile, yana ikuku epoxy klaasị F nwere oghere, na-etolite sistemu mkpuchi siri ike, iru mmiri{1} na nke na-ekpo ọkụ.

2.3 ikpeazụ mgbakọ

A na-achịkọta isi ihe ndị a kpụrụ akpụ na ikuku, n'oge a na-eme njikọ eletriki, mkpuchi, na nhazi nhazi.

N'okpuru oghere, a na-awụsa resin epoxy n'etiti windings na isi, na-eme ka usoro siri ike, gwọọ.

Mgbe mgbakọ na ọgwụgwọ gasịrị, a na-eme usoro ule eletriki na ígwè ọrụ iji hụ na onye na-agbanwe agbanwe na-ezute ụkpụrụ nhazi na nchekwa.

Nke a 2100 kVA resin nkedo ụdị nkesa ihe ngbanwe a, bụ nke ahaziri maka onye ahịa South Africa. Ihe ngbanwe a dabara adaba maka igwe ọrụ dị arọ-, nnukwu moto, na akụrụngwa nhazi na ngwa Ngwuputa na ngwa nrụpụta chọrọ nnukwu ibu. SCOTECH dị njikere ịnye ahaziri ọkachamara na ọrụ dị mma iji gboo ihe ị chọrọ.

Dị ka ọkachamara na-emepụta ihe ngbanwe ụdị akọrọ, SCOTECH na-enye ngwaahịa ndị kwekọrọ n'ụkpụrụ mba ụwa dịka IEC, ANSI/IEEE, NEMA, CSA, na BS. Ụdị ihe ngbanwe resin nke akọrọ anyị na-ekpuchi ike sitere na 50 kVA ruo 15 MVA, yana nnukwu voltaji ruo 36 kV. Ma ugboro 50 Hz na 60 Hz dị, yana njikọ delta ma ọ bụ kpakpando. A na-ekpuchi windings voltaji nke etiti na resin epoxy, yana klas mkpuchi sitere na A, E, B, F ruo H, yana ọkwa nchebe nwere ike ịhazi ya site na IP 2X ruo IP 4X.

Nhọrọ oyi na-agụnye oyi ikuku eke (ONAN) na mmanye ikuku jụrụ oyi (ONAF), nke nwere otutu ihe mmetụta okpomọkụ na relays okpomọkụ maka nchebe ọkụ a pụrụ ịdabere na ya.
