Perkins Generator EMC Design Criteria

Nhazi ndakọrịta elektrọnik nke Perkins generator maka ojiji etiti data.

(1) Jiri ma nye egwuregwu zuru oke maka ndakọrịta elektrọnik nke akụrụngwa eletrọnịkị eji.Gụnyere: ① ịhọrọ akụrụngwa eletrọnịkị nwere nnukwu nnabata mgbaama;② Họrọ akụrụngwa eletrọnịkị nwere ọsọ kwesịrị ekwesị;③ Belata mgbochi ntinye nke sekit ntinye (karịsịa sekit ntinye ihe dịpụrụ adịpụ) dị ka o kwere mee;④ Belata mgbochi mmepụta nke ọma.

(2) Ike ọkọnọ usoro imewe nke Perkins diesel generator .Gụnyere: ① họrọ modul ike nke nwere obere ikike njikọ dị n'akụkụ nke mbụ na akụkụ nke abụọ na nnukwu njikọ njikọta na ala n'akụkụ isi;② Nabata usoro ike kesara dị ka o kwere mee;③ Oke arụ ọrụ nke voltaji AC nke modul ike ga-abụrịrị nnukwu.

(3) Nhọrọ nke grounding mode.① N'ozuzu, a na-anakwere grounding ozugbo;② Mgbe a na-ejikọta akụkụ njikwa ọkụ eletrik na akụrụngwa voltaji dị elu, a na-anabata ọnọdụ ala na-ese n'elu mmiri;③ A ga-achịkwarịrị ike nkesa nkesa nke sistemu ala na-ese n'elu mmiri.

(4) Nhazi nke ikesa ike nke sistemu njikwa.① Gbalịa belata njikọ njikọ n'etiti isi na nke abụọ iji gbochie ụzọ nke nnyonye anya nkịtị;② A na-ekpuchi mgbanaka magnetik na-emekarị n'ebe ntinye nke ọdụ ụgbọ mmiri ahụ, mgbe ahụ, a na-ejikọta ọnụ ọgụgụ dị elu nke ogologo oge na ala;③ Debe waya mgbada n'ebe waya mgbama ndị ọzọ nọ;④ Belata ikike nkesa nke usoro;⑤ Nyochaa ike nkesa nke akụkụ nke ọ bụla n'ala, nyochaa nkesa nkesa nke nnyonye anya ọnọdụ nkịtị, tụọ mmetụta nke nnyonye anya ụdịdị nkịtị, wee mepụta usoro teknụzụ iji kwụsị nnyonye anya.

Kedu ihe bụ isi ihe ngosi teknụzụ nke nnukwu mgbaàmà na obere njirimara mgbaàmà?

Isi ihe nrịbama teknụzụ nke sistemu mkpali gụnyere:

(1) Main teknuzu indexes nke nnukwu mgbaàmà e ji mara: ① maka ot nzaghachi excitation usoro, na oru indexes bụ top voltaji multiple na excitation voltaji nzaghachi ruru;② Maka usoro mkpali na nzaghachi mbụ dị elu, ntinye aka na teknụzụ bụ ọtụtụ voltaji dị elu na oge nzaghachi voltaji na-akpali akpali.

(2) The isi teknuzu indexes nke obere mgbaàmà àgwà bụ: ịrị elu oge, mgbanwe oge, overshoot na oscillation ugboro.Ndekọ ọkọlọtọ bụ: overshoot ≤ 50%, oge mgbanwe ≤ IOS, oge oscillation ≤ 3 ugboro.

Kedu ihe kpatara tụọ mkpuchi ngwa ngwa rotor mgbe a malitere generator?Maka ụfọdụ rotors generator, mmejọ ọdịda nke generator rotor winding na-ejikọkarị ya na ike centrifugal mgbe rotor na-atụgharị, mana ụdị mmejọ a enweghị ike igosipụta n'ule n'okpuru mmechi.Ya mere, mgbe generator na-ebili site na ọsọ efu gaa na ọsọ ọsọ, ịlele mkpuchi nke rotor winding n'oge a nwere ike ikpebi ma enwere mmejọ dị otú ahụ na ikuku rotor, iji chọpụta n'ụzọ ziri ezi ma hụ na ọ dịghị ihe ize ndụ zoro ezo. ọrụ nkịtị nke rotor winding.

Semiconductor excitation regulator

N'ime usoro mkpali nke semiconductor, ihe na-akpali akpali bụ semiconductor rectifier na ọkụ ọkụ AC ya, onye na-ahụ maka ihe na-eme ihe na-emepụta ihe na-emepụta ihe mejupụtara semiconductor, ihe siri ike na sekit eletrọnịkị.Onye na-ahụ maka mmalite gosipụtara naanị ngbanwe voltaji generator wee mee mgbazi voltaji.A na-akpọkarị voltaji regulator (voltaji regulator maka mkpụmkpụ).Onye na-achịkwa ugbu a nwere ike igosipụta n'ụzọ zuru ezu ụdị njikwa njikwa dị iche iche gụnyere mgbama mgbanaka voltaji maka iwu mkpali, yabụ a na-akpọ ya onye na-ahụ maka mgbake.N'ụzọ doro anya, onye na-ahụ maka excitation na-agụnye ọrụ nke njikwa voltaji.
