Gịnị bụ mmetụta nke oké mkpali ọnwụ na Generator

N'oge ọrụ nkịtị nke generator, mkpali ahụ na-apụ na mberede kpamkpam ma ọ bụ akụkụ ụfọdụ, nke a na-akpọ ọnwụ nke excitation nke generator.

N'ime ihe ndị dị na mmanụ dizel generator set, generator dị ezigbo mkpa.Ka ejiri ogologo oge ejiri igwe na-emepụta mmanụ diesel, igwe na-emepụta ihe nwere ike ịla n'iyi.Ọnọdụ a bụ ihe nkịtị.Ma ọnọdụ a ga-emetụta usoro ahụ. Gịnị bụ mmetụta nke excitation loass na generator?

1.Low-excitation na ọnwụ-nke-excitation generators na-amịkọrọ ike reactive si usoro, na-eme ka voltaji nke ike usoro ịdaba.Ọ bụrụ na reactive ike idobere na ike usoro bụ ezughi oke, voltaji nke ụfọdụ ihe na ike usoro ga-adị ala karịa The allowable uru ebibi anụ ọrụ n'etiti ibu na onye ọ bụla ike isi iyi, na ọbụna na-akpata voltaji nke ike usoro. daa.

2.Mgbe a generator tụfuru mkpali ya, n'ihi voltaji dobe, ndị ọzọ generators na ike usoro ga-amụba ha reactive ike mmepụta n'okpuru edinam nke akpaka ukpụhọde nke excitation ngwaọrụ, si otú na-eme ka ụfọdụ. ndị na-emepụta ihe , Transformers ma ọ bụ ahịrị na-agafe agafe , Nchekwa ndabere ya nwere ike ime ka ọ ghara ịrụ ọrụ n'ihi na ọ na-emebiga ihe ókè, nke ga-agbasawanye ihe mberede ahụ.

3.Mgbe a generator tụfuru magnetization ya, n'ihi na swing nke generator si arụ ọrụ ike na dobe nke usoro voltaji, o nwere ike ime ka n'akụkụ nkịtị arụ ọrụ generators na usoro, ma ọ bụ n'etiti akụkụ dị iche iche nke ike usoro, ida. mmekọrịta, na-eme ka usoro ahụ kwụsị mmekọrịta.Oscillation na-eme.

4.The ukwuu gosiri ike nke generator, ukwuu nke reactive ike mpe nke mere site ala excitation na ọnwụ nke excitation, na obere ikike nke ike usoro, ndị nta ikike iji kwụọ ụgwọ nke a reactive ike mpe.Ya mere, ọnụ ọgụgụ dị ukwuu nke otu onye na-emepụta ihe na-arụ ọrụ na ike zuru ezu nke usoro ike, otú ahụ ka mmetụta ọjọọ na-emetụta usoro ike.

Kedu ihe kpatara ọnwụ nke mkpali nke generator?

(1) Akara ngosi mgbe generator tụfuru mkpali ya: stator ugbu a na ike na-arụ ọrụ nke generator na-ebili ngwa ngwa mgbe otu ntabi anya dobe, na ruru na-abawanye na-amalite siwing.

(2) The generator ka nwere ike izipu ụfọdụ ego nke na-arụsi ọrụ ike ike mgbe ọnwụ nke excitation, na-na-nduzi nke arụ ọrụ ike ezipụ, ma pointer nke ike mita swings kwa oge.

(3) Ka stator ugbu a na-abawanye, akara ammeter ya na-atụgharị kwa oge.

(4) Site na ike reactive nke ezigara ruo na ike mmeghari etinye uche, ihe ntụnye ahụ na-efegharị kwa oge.Ọnụ ọgụgụ nke ike reactive na-etinye uche n'ihe dị ka nha nha nke ike mmeghachi omume tupu ọnwụ nke mkpali.

(5) The rotor sekit na-akpali ọzọ na-agbanwe agbanwe ugbu a na ike magnetomotive ike na-atụgharị ugboro ugboro, ya mere pointer nke rotor voltmeter na-atụgharị kwa oge.

(6) Ihe nrịbama nke rotor ammeter na-emegharị kwa oge, na uru dị ugbu a dị ntakịrị karịa nke ahụ tupu nkwụsị nke mkpali.

(7) Mgbe sekit rotor meghere, a na-akpalite ụfọdụ eddy ugbu a n'elu rotor ahụ iji mepụta oghere magnetik na-atụgharị, nke na-ewepụtakwa ụfọdụ ike asynchronous.

Olee otú obibi nsogbu nke excitation ọnwụ nke generator?
