Ntọala mmanụ dizel dakọtara na UPS

Edemede a na-enyocha ma na-akọwa mmetụta nke ihe ntinye ike ntinye UPS na ntinye ntinye na ike generator iji dokwuo ihe kpatara nsogbu ahụ, wee chọta azịza ya.

1. Nchikota n'etiti dizel generator set na UPS.

Ndị na-emepụta na ndị na-arụ ọrụ nke sistemu ọkụ na-adịghị akwụsị akwụsị achọpụtala nsogbu nhazi dị n'etiti igwe na-emepụta ọkụ na UPS, karịsịa nkwekọ dị ugbu a nke ndị na-emezigharị na-emepụta na-emepụta na usoro ọkụ ọkụ dị ka voltaji regulators nke generator sets na synchronization circuits nke UPS.Mmetụta ọjọọ nke nke a pụtara nnọọ ìhè.Ya mere, ndị injinia sistemu UPS haziri ntinye ntinye wee tinye ya na UPS, na-ejikwa nke ọma nkwekọ dị ugbu a na ngwa UPS.Ihe nzacha ndị a na-arụ ọrụ dị mkpa na ndakọrịta nke UPS na usoro generator.

Ihe fọrọ nke nta ka ọ bụrụ ihe nzacha ntinye niile na-eji capacitors na inductor na-enweta nkwekọ kachasị njọ ugbu a na ntinye UPS.Nhazi nke nzacha ntinye na-eburu n'uche pasent nke oke nkwekọ nkwekọ zuru oke nke dị na sekit UPS na n'okpuru ibu zuru oke.Uru ọzọ nke ọtụtụ nzacha bụ imeziwanye ihe ntinye ike nke UPS eburu.Agbanyeghị, nsonaazụ ọzọ sitere na ntinye ntinye ntinye bụ iji belata arụmọrụ UPS zuru oke.Ọtụtụ nzacha na-eri ihe dịka 1% nke ike UPS.Nhazi nke ntinye ntinye na-achọ mgbe niile nguzozi n'etiti ihe dị mma na nke na-adịghị mma.

Iji kwalite arụmọrụ nke usoro UPS dị ka o kwere mee, ndị injinia UPS emela mmelite n'oge na-adịbeghị anya na oriri ike nke ntinye ntinye.Ọganihu nke nzacha nzacha dabere na ntinye teknụzụ IGBT (Insulated Gate Transistor) na nhazi UPS.Ịrụ ọrụ dị elu nke IGBT inverter emeela ka ọ gbanwee UPS.Ihe nzacha ntinye nwere ike ịmịkọrọ ụfọdụ harmonics dị ugbu a ka ọ na-etinye obere akụkụ nke ike nọ n'ọrụ.Na nkenke, a na-ebelata ihe ndị na-emepụta ihe na ihe ndị na-emepụta ihe na nzacha, na-ebelata olu nke UPS, na-arụ ọrụ nke ọma.Ihe dị na mpaghara UPS yiri ka edozila ya, ma ndakọrịta nke nsogbu ọhụrụ na generator apụtala ọzọ, dochie nsogbu ochie.

2. Nsogbu resonance.

Nsogbu nke mkpali onwe onye capacitor nwere ike ịkawanye njọ ma ọ bụ kpuchie ya site na ọnọdụ eletriki ndị ọzọ, dị ka usoro resonance.Mgbe uru ohmic nke generator's inductive reactance na ohmic uru nke ntinye nzacha capacitive reactance dị nso na ibe ya, na uru nguzogide nke usoro ahụ dị ntakịrị, oscillation ga-eme, na voltaji nwere ike gafere uru nke ike. usoro.Sistemu UPS emebere ọhụrụ bụ n'ezie 100% impedance capacitive.UPS 500kVA nwere ike inwe ikike nke 150kvar yana ihe ike dị nso na efu.Shunt inductor, usoro chokes, na ntinye ihe ngbanwe dị iche iche bụ ihe a na-emekarị nke UPS, ihe ndị a niile na-emepụta ihe.N'ezie, ha na capacitance nke nzacha ọnụ na-eme ka UPS na-akpa àgwà dị ka capacitive n'ozuzu ya, na enwere ike ịnweworị ụfọdụ oscillations n'ime UPS.Ejikọtara ya na njirimara capacitive nke eriri ike jikọtara na UPS, mgbagwoju anya nke usoro dum na-abawanye nke ukwuu, gafere nyocha nke ndị injinia nkịtị.

3. Diesel generator set na ibu.

Ndị na-emepụta mmanụ dizel na-adabere na onye na-ahụ maka voltaji iji jikwaa voltaji mmepụta.Onye na-ahụ maka voltaji na-achọpụta voltaji mmepụta nke ụzọ atọ ma jiri nkezi uru ya tụnyere ihe achọrọ voltaji.Onye na-achịkwa na-enweta ike site na isi iyi inyeaka n'ime generator, na-abụkarị obere generator coaxial na isi generator, na-ebufe DC ike na magnetik excitation eriri igwe nke generator rotor.Igwe mmiri dị ugbu a na-ebili ma ọ bụ daa iji chịkwaa oghere ndọta na-atụgharị nke generator stator eriri igwe , ma ọ bụ nha nke ike electromotive EMF.Igwe magnetik nke eriri stator na-ekpebi voltaji mmepụta nke generator.

Nguzogide n'ime nke eriri stator nke igwe na-emepụta mmanụ dizel bụ nke Z na-anọchi anya ya, gụnyere akụkụ inductive na mgbochi;ike electromotive nke generator nke rotor excitation coil na-achịkwa bụ E site na isi iyi voltaji AC.Na-eche na ibu ahụ bụ naanị inductive, nke ugbu a m na-akwụ ụgwọ voltaji U site na 90º elekere eletrik na eserese vector.Ọ bụrụ na ibu ahụ bụ ihe mgbochi, vectors nke mụ na U ga-adaba ma ọ bụ na-aga n'ihu.N'ezie, ọtụtụ ibu dị n'etiti naanị resistive na naanị inductive.Mbelata voltaji nke ugbu a na-agafe na eriri stator na-anọchi anya vector I × Z.Ọ bụ n'ezie nchikota nke abụọ obere voltaji vector, mgbada voltaji na-eguzogide na-adọ na I na inductor voltaji dobe 90° n'ihu.Na nke a, ọ na-eme na-na-adọ na U. N'ihi na electromotive ike ga- hà na nchikota nke voltaji dobe nke generator si esịtidem nguzogide na mmepụta voltaji, ya bụ, vector nchikota nke vector E = U na I ×Z.Onye na-ahụ maka voltaji nwere ike ijikwa voltaji U nke ọma site n'ịgbanwe E.

Ugbu a, tụlee ihe na-eme ọnọdụ dị n'ime nke generator mgbe a na-eji ihe na-arụ ọrụ nke ọma eme ihe kama ibu ibu na-emepụta ihe.Ihe dị ugbu a n'oge a bụ ihe dị iche na ibu inductive.Ugbu a m na-eduga ugbu a voltaji vector U, na esịtidem iguzogide voltaji dobe vector I×Z bụkwa na-abụghị akụkụ.Mgbe ahụ ọnụọgụ vector nke U na I×Z erughị U.

Ebe ọ bụ na otu ike electromotive E dị ka ibu inductive na-arụpụta voltaji mmepụta dị elu nke U na ibu capacitive, onye na-ahụ maka voltaji ga-ebelata nke ukwuu oghere magnetik na-atụgharị.N'ezie, onye na-achịkwa voltaji nwere ike ọ gaghị enwe oke zuru oke iji chịkwaa voltaji mmepụta nke ọma.The rotors nke niile generators na-anọgide na-enwe obi ụtọ n'otu ntụziaka na nwere a magnetik na-adịgide adịgide.Ọbụna ma ọ bụrụ na onye na-ahụ maka voltaji emechiela nke ọma, rotor ka nwere oghere magnet zuru ezu iji kwụọ ibu capacitive ma mepụta voltaji.A na-akpọ ihe a na-akpọ "mkpali onwe onye".Nsonaazụ nke mkpali onwe onye bụ oke voltaji ma ọ bụ nkwụsị nke onye na-ahụ maka voltaji, na sistemụ nleba anya nke generator na-ewere ya dị ka ọdịda nke njikwa voltaji (ya bụ, “mfu nke mkpali).Nke ọ bụla n'ime ọnọdụ ndị a ga-eme ka generator kwụsị.Ibu ejikọrọ na mmepụta nke generator nwere ike ịnọrọ onwe ya ma ọ bụ ihe yiri ya, dabere na oge na ntọala nke kabinet mgbanwe akpaka.N'ime ngwa ụfọdụ, usoro UPS bụ ibu mbụ ejikọrọ na generator n'oge ọdịda ike.N'ọnọdụ ndị ọzọ, UPS na ibu ọrụ na-ejikọta n'otu oge.The n'ibu ibu na-enwekarị onye na-amalite contactor, na ọ na-ewe oge ụfọdụ reclose mgbe a ike ọdịda.Enwere igbu oge n'ịkwụghachi ibu moto inductive nke capacitor ntinye ntinye UPS.UPS n'onwe ya nwere oge a na-akpọ "mmalite dị nro", nke na-ebufe ibu site na batrị gaa na generator iji welie ihe ntinye ike ya.Agbanyeghị, ihe nzacha ntinye UPS anaghị eso na usoro mmalite dị nro.Ejikọtara ha na njedebe ntinye nke UPS dịka akụkụ nke UPS.Ya mere, n'ọnọdụ ụfọdụ, isi ibu nke mbụ jikọtara na mmepụta nke generator n'oge ọdịda ike bụ ntinye ntinye nke UPS.Ha na-enwe oke ike (mgbe ụfọdụ naanị capacitive).

Ihe ngwọta maka nsogbu a bụ n'ụzọ doro anya iji mgbazi ihe ike.Enwere ọtụtụ ụzọ iji nweta nke a, dịka ndị a:

1. Wụnye akpaka ịmafe kabinet na-eme ka moto ibu jikọọ tupu gbasie.Ụfọdụ ụlọ ngbanwe nwere ike ọ gaghị enwe ike itinye usoro a.Na mgbakwunye, n'oge a na-arụzi ihe, ndị injinia ihe ọkụkụ nwere ike ịdị mkpa ka ha mebie UPS na ndị na-emepụta ọkụ.

2. Tinye a na-adịgide adịgide reactive reactance iji kwụọ ụgwọ capacitive ibu, na-emekarị na-eji a yiri winding reactor, jikọọ na EG ma ọ bụ generator mmepụta yiri osisi.Nke a dị nnọọ mfe iji nweta, na ọnụ ahịa dị ala.Ma n'agbanyeghị na ibu dị elu ma ọ bụ dị ala, reactor na-etinye oge niile ugbu a ma na-emetụta ihe ike ibu.Na n'agbanyeghị ọnụ ọgụgụ nke UPS, a na-edozi ọnụ ọgụgụ nke reactors mgbe niile.

3. Wụnye ihe inductive reactor na onye ọ bụla UPS ka dị nnọọ akwụ ụgwọ maka capacitive reactance nke gbasie.N'ihe banyere ibu dị ala, onye kọntaktị (nhọrọ) na-achịkwa ntinye nke reactor.Usoro a nke reactor bụ nke ziri ezi karị, ma ọnụ ọgụgụ ahụ buru ibu na ọnụ ahịa ntinye na njikwa dị elu.

4. Wụnye onye kọntaktị n'ihu capacitor nzacha ma kwụpụ ya mgbe ibu dị ala.Ebe ọ bụ na oge kọntaktị ga-abụrịrị nkenke na njikwa ahụ dị mgbagwoju anya, ọ nwere ike itinye ya na ụlọ ọrụ mmepụta ihe.

Kedu usoro kachasị mma dabere na ọnọdụ dị na saịtị na arụmọrụ nke akụrụngwa.
