01 Izugbe

1.1 Ihe ndabere oru ngo

Ihe oru ngo a gụnyere inye 500 kVA atọ -phase pad - nkwụnye nkesa nkesa, emebere maka sistemu 60 Hz na voltaji bụ isi nke 13.2 kV GrdY / 7620 V na voltaji nke abụọ nke 480 V. Ihe ntụgharị nwere atụmatụ ONAN (Oil Natural Air Natural) na-eme ka obi dị jụụ, na-arụ ọrụ nchekwa nchekwa, ma na-eme ka nhazi nri nwuru anwu. Ejiri otu vector YNd1 wuo ya ma nwee ihe mgbochi nke 5.75%.

Emepụtara ya na nrube isi n'ụkpụrụ nrụpụta ike ike DOE 2016, ihe mgbanaka 500 kva na-ebunye ihe nrụnye dị elu na mfu ume dị ala{3}}5.75 kW enweghị ibu na ọnwụ 0.65 kW n'ike.

Nke a 500 kVA 13.2 kV / 480 V atọ -phase pad - mgbakwasa transformer dị mma maka ọkara{5}}voltaji ruo ala- nkesa voltaji na obodo mepere emepe na mpaghara ime obodo. Ngwa a na-ahụkarị gụnyere:

• Obodo obibi, na-enye ike maka ọkụ ọkụ, HVAC, na ngwa ụlọ

• Ụlọ ahịa dị ka ụlọ ọrụ, nnukwu ụlọ ahịa, na ogige ndị na-ere ahịa

• Ụlọ ọrụ mmepụta ihe dị ọkụ, na-enye ike obere ruo etiti{0} akụrụngwa na igwe

• Ụlọ ọrụ dị ka ụlọ akwụkwọ na ụlọ ọgwụ chọrọ ike a pụrụ ịdabere na ya na nchekwa

• Sistemụ nkesa n'okpuru ala, ejiri na netwọk ndepụta loop maka nkwalite ntụkwasị obi na nchekwa

Mpempe akwụkwọ ya- atụkwasịkwara, loop{1} nri, yana nwụrụ anwụ{2} imewe ihu na-eme ka ọ dabara maka nrụnye n'èzí ma ọ bụ n'ala{3} ebe oghere, nchekwa na nnweta bụ isi.

2.1 Isi

Nhazi isi ụkwụ ise - na-eme ka ụzọ mgbagharị magnetik kwụ ọtọ maka usoro atọ niile. Ọbụna n'okpuru efu -usoro mmiri - dị ka nke otu -ahịrị - na -mmejọ ala{7}}ma ọ bụ n'oge ọnọdụ nbudata na-ezighi ezi, magnetik flux nwere ike na-aga nke ọma site na ụkwụ mpụta abụọ. Nke a na-ebelata enweghị mmasị magnetik, na-ebelata ịrị elu okpomọkụ, ma na-ebelata ịma jijiji.

Nhazi isi a bara uru nke ukwuu maka ndị na-agbanwe ihe nke YNd vector, n'ihi na ọ na-enye ụzọ doro anya maka mgbanwe efu-usoro mgbe kpakpando - jikọtara elu dị elu{2}} voltaji n'akụkụ na-anọpụ iche gbadoro ụkwụ, wee na-eme ka nkwụsi ike eletrik na ntụkwasị obi sistemụ.
