1000 KVA Pad Nkwanye Onye na-emepụta ihe na-emepụta ihe-12.47 / 0.48 KV|USA 2025

01 Izugbe

1.1 Ihe ndabere na ngwa

Ebutere ya na United States na 2025, a na-etinye 1000kVA pad pad atọ awụnyere n'ime usoro nkesa n'okpuruala{2}Fed ebe a na-atụ anya ịrụ ọrụ na-aga n'ihu, mgbanwe ngwa ngwa na ogologo oge{3} na nkwụsi ike oge na ọnọdụ ubi, ọ bụghị naanị na akwụkwọ.

N'ime ụdị netwọkụ a, a naghị emeso ihe ngbanwe nke mpe mpe akwa dị ka nkeji ngbanwe dị mfe; ọ na-eme ka ọnụ ọkụ eletrik edobere n'ime grid nkesa, ebe mgbanwe ibu, mmejọ, na mgbanwe voltaji niile na-agafe na a ga-ejikwa ya nke ọma.

Enyere ya na 12.47kV ruo 0.48kV, ihe mgbakwasa pad ahụ dabara na ọkọlọtọ North America ọkara - ruo - sistemu voltaji dị ala, nke a na-ejikarị na ngwa azụmahịa, ụlọ ọrụ ọkụ, na ngwa akụrụngwa nwere profaịlụ ibu agwakọta yana dị ike.

1.2 Nhazi voltaji na otu vector (YNd1)

Nke a1000kVA mpe mpe akwa arịọnụ transformerna-eji 12.47kV grounded wye primary na 0.48kV delta secondary, YNd1 vector group, ahọpụtara iji jikwaa omume ala, usoro nkwekọ, na enweghị ahaghị nhata na sistemu nkesa bara uru.

Akụkụ wye a gbanyere mkpọrọgwụ na-eme ka nkwụsi ike nke sistemu na ịchọpụta mmejọ, ebe ikuku delta na-enyere aka ibelata harmonics atọ ma gbochie mgbasawanye ọgba aghara, ọkachasị mgbe igwe nrụnye na-ebunye ibu na-adịghị adị dịka VFDs, sistemu UPS, ma ọ bụ ọdụ ụgbọ mmiri EV.

1.3 Mkpebi Mkpebi (5.75%)

Na 5.75% impedance, pad a na-ekpunye transformer na-eme ka mkpirisi - mmachi okirikiri ugbu a, ụkpụrụ voltaji, na nhazi nchedo.

Ọ na-enyere aka ịchịkwa ọkwa mmejọ, na-akwado nchikota nke mmebi, ma na-edobe omume voltaji kwụsiri ike n'oge mgbanwe dị iche iche nke ibu, na-ahụ na ọrụ a pụrụ ịdabere na ya n'okpuru ma ọnọdụ nkịtị na nke na-agafe agafe.

1.4 Nkọwa nka nka

1000kVA atọ na-adọ mpe mpe akwa ndokwasa transformer nkọwa na data mpempe akwụkwọ

1.5 Eserese

1000kVA atọ akụkụ mpe mpe akwa ndokwasa transformer ịbịaru na nameplate

02. Nhazi usoro, mkpuchi, nnabata na nchekwa

2.1 Nhazi usoro nkesa

Nke a 1000kVA atọ mpempe mpe mpe akwa ndokwasa transformer adopter a loop ndepụta na nwụrụ anwụ n'ihu Ọdịdị, na-enyere nchekwa ọrụ na-aga n'ihu ike ịmafe na North America n'okpuruala usoro nkesa.

N'ime ngwa ọrụ na ọrụ azụmahịa, a na-eji nhazi ihe nrụnye mgbanaka pad a ebe a na-achọ nkwụsi ike ogologo oge na ọrụ nchekwa nchekwa.

2.2 Arụmọrụ mkpuchi (mmanụ FR3)

Ihe ngbanwe a na-etinye na pad na-eji FR3 eke ester fluid, na-eme ka arụ ọrụ nchekwa ọkụ na-arụ ọrụ, nnabata gburugburu ebe obibi, yana nkwụsi ike mkpuchi ogologo oge{{1}.

N'oge nrụpụta, a na-achịkwa ihicha agụụ, ndochi mmanụ na usoro akara iji hụ na arụ ọrụ dielectric kwụsiri ike nke ihe mgbakwasa pad n'okpuru ezigbo ọnọdụ ọrụ.

2.3 Nrube isi na nchekwa

Ihe mgbakwasa ihe mkpuchi ahụ na-agbaso ihe achọrọ arụmọrụ DOE yana ụkpụrụ IEEE C57.12.34, na-ahụ na ndakọrịta na grid North America na nnabata akụrụngwa.

Nkwado nnabata UL/cUL na nhazi njide ịwa ahụ na-ejikọkarị ọnụ iji kwalite ntụkwasị obi arụmọrụ yana arụmọrụ nchekwa.

03 Isi ihe nrụpụta

3.1 Isi na Winding

A na-eji ígwè silicon ọkwa dị elu{0}} maka isi iji belata mfu, ebe ikuku aluminom na-enye nguzozi n'etiti arụmọrụ ọnụ ahịa yana arụmọrụ ọkụ.

Ejiri usoro nrụpụta ihe a na-achịkwa nke ọma iji hụ na arụmọrụ kwụsiri ike n'okpuru ibu na-aga n'ihu na mkpụmkpụ- ọnọdụ okirikiri.

3.2 Nhazi tank

Tankị a mechiri emechi nwere mkpuchi ntụ ntụ RAL 9003 na-eme ka nguzogide corrosion na ogologo oge- dị n'èzí.

A na-etinye usoro akara siri ike na usoro ọgwụgwọ elu iji hụ na a pụrụ ịdabere na pad na-agbanye n'ọnọdụ ọnọdụ gburugburu ebe obibi siri ike.

04 mbukota na njem

05 Saịtị na nchịkọta

Nke a 1000kVA pad pad mounted transformer bụ maka ọrụ a pụrụ ịdabere na ya na sistemụ nkesa North America, na-ejikọta nchekwa, arụmọrụ na arụmọrụ gburugburu ebe obibi.

Site na imewe ruo n'ichepụta, ihe a na-elekwasị anya bụ ịhụ na ihe ngbanwe nke ọ bụla nwere ike ịrụ ọrụ nke ọma na gburugburu grid site na nrube isi na ogologo oge{{0}.
