Umuvuduko ukabije wa mazutu yashizeho gahunda yo guhindura umuvuduko mwinshi

Abstract: Amashanyarazi ya voltage ntoya kuri ubu aribwo buryo bwihutirwa bwo gukoresha ingufu kubakoresha benshi, kandi iyi moderi mubisanzwe yerekeza kuri 230V / 400V ya moteri ikoreshwa mumasoko.Icyakora, ahantu hamwe na hamwe, kubera intera iri hagati yicyumba cya moteri ya mazutu n’ibikoresho by’amashanyarazi, hashobora kubaho ibitonyanga bya voltage, bigatuma badashobora gukoresha amashanyarazi bisanzwe, ndetse no mu bihe bikomeye, ndetse bagatwika ibikoresho by’amashanyarazi.Kubwibyo, kubakoresha bamaze kugura amashanyarazi make ya mazutu yamashanyarazi, gufata ingamba zo kuzamura kuva kumuvuduko muke ukagera kumuvuduko mwinshi bihinduka inzira nziza, kugirango udakuraho umwimerere wa moteri itanga ingufu nkeya kandi bigatera igihombo kinini mubukungu.

1 、 Kugereranya ibyiza nibibi byumuvuduko mwinshi kandi muto

1. Ibyiza bya moteri itanga amashanyarazi menshi:

.Ibi ni ukubera ko, iyo bisohora ingufu zimwe, ikigezweho cya generator yumuriro mwinshi irashobora kuba nto cyane ugereranije niy'amashanyarazi make.Imashini itanga amashanyarazi menshi rero irashobora gukoresha diameter ntoya.Nkigisubizo, gutakaza umuringa wa stator ya generator yumuriro mwinshi nabyo bizaba bito ugereranije nibyuma bitanga ingufu nke.Kumashanyarazi afite ingufu nyinshi, mugihe ukoresheje ingufu za voltage nkeya, hasabwa umwanya munini wa stator bitewe no gukenera insinga nini, bikavamo diameter nini ya stator nini hamwe nubunini bunini bwa generator yose;

.By'umwihariko kuri 10KV itanga amashanyarazi menshi, barashobora gukoresha mu buryo butaziguye amashanyarazi, azagabanya ishoramari mu bikoresho by'amashanyarazi, koroshya imikoreshereze, kandi bigabanye igipimo cyo gutsindwa.

2. Ingaruka za generator yumuriro mwinshi

.

.

2 method Uburyo bwo kuzamura amashanyarazi

Ahantu hasabwa amashanyarazi menshi, usibye kugenerwa amashanyarazi menshi, amashanyarazi asanzwe hamwe na transformateur-intambwe nayo irashobora gukoreshwa.

1. Ibyiza byumuvuduko muke kuri gahunda ya voltage nini

.

(2).Hatariho umurongo wa zeru, nta murongo wa zeru woherejwe;Gutandukanya ubwuzuzanye buterwa n'imitwaro itari kumurongo kuruhande rwumuvuduko mwinshi uva kuruhande rwa voltage nkeya, bigatuma uruhande ruke rwa voltage ruba rufite isuku kandi ntirugire ingaruka kumikorere yumuteguro wa voltage wikora (AVR) imbere ya generator, kimwe no gukemura ibibazo bitandukanye biterwa no kwimura umurongo wa zeru;

(3) Imikorere ikomeye ya Inertia ifasha cyane mugutangiza moteri nini.Impinduka nini zububasha zirimo ibintu byinshi byumuringa, kandi nini nini ya magneti ifite uruhare runini, bigabanya ingaruka kuri generator no kunoza umuvuduko wa voltage ako kanya.

2. Ingaruka za Gahunda yo Kuringaniza Gahunda ya Generator Ntoya

Muri generator ya 380-415Vac, niba amashanyarazi menshi yahujwe ahwanye kuruhande rwa voltage ntoya hanyuma akazamurwa na transformateur-intambwe;Icyifuzo cyo hejuru gisabwa ni 7500 kVA, 6000 kWt.Iyo urenze imipaka yo hejuru, hagomba gusuzumwa ibintu bikurikira: -

Ubushobozi bwumubyigano muto wa busbar bugomba kuba hafi ya 10kA, urebye ubushobozi bwa busbar bwo guhangana ningaruka zumuriro hamwe nubuvuzi bwubushyuhe imbere mumashanyarazi make (kuzamuka kwubushyuhe bwa ecran ya voltage ntoya);

• Ubushobozi bwo kugendagenda kuri voltage ntoya (kugeza guhangana ningaruka zumuriro), nka 65kA na 100kA;

• Birakenewe kubara niba kwishyiriraho insinga za ampere hafi 10000, guhinduranya amashanyarazi make, hamwe nigiciro kuruhande rwa voltage nkeya birumvikana;

3 case Urubanza rwo kuvugurura

1. Ibikoresho nibikoresho

Umukoresha: Umushinga muri Macau

Kubika amashanyarazi: UPS + 6000kVA

Ubushobozi bwihutirwa bwose: 4500kVA, 3600kW

Sisitemu ya voltage: Umuvuduko mwinshi 11kV, 50Hz na voltage nto 415 Vac50Hz

Imbaraga: Moderi 4 ya KTA50-GS8 / amashanyarazi ya 1200kW

Imashini itanga amashanyarazi: 3 nyamukuru na 1 backup, hamwe 1 yagenewe kubungabunga.Buri generator irashobora guhuzwa na gride ya power kugirango ikoreshwe

Imashini itanga amashanyarazi: 415Vac / ibyiciro bitatu / 50 cycle

Screen Umuvuduko muke wa ecran ya ecran ya generator:

5000A busbar / amasegonda 80kA1 / ibyiciro bitatu-bine insinga / 50 cycle

BusA 5000A igabanijwemo ibice A na B.

Igice A cya busbar ihujwe na generator ebyiri, imwe na ebyiri

Igice B cya busbar ihujwe na generator ebyiri, 3 na 4

Kwinjiza 5000A4 pole ihuza imiyoboro ya busbar ibice A na B.

○ 4 × 2500A guhinduranya ikirere → ihujwe na 4 ya generator

3 × 3200A guhinduranya ikirere → ihujwe na 3 intambwe yo hejuru (uruhande ruke rwa voltage)

Transform Guhindura intambwe: amaseti 3 ya 2000kVA11kV / 0.415kV

Screen Umuyoboro mwinshi wa ecran ya transformateur: vacuum switch, 15kV600A → ihujwe na 3-intambwe ihinduranya (uruhande rwo hejuru rwa voltage)

2. Isesengura rya gahunda

.Hatitawe ku gice gikeneye kubungabungwa, ntabwo bigira ingaruka kumashanyarazi yihutirwa;

. -guhindura amashanyarazi kugirango itange ingufu mu turere dutandukanye;

.Gukemura mu buryo butaziguye ibibazo byo kubika ibikoresho byaka, umwotsi w’umwotsi, n urusaku rwatewe nicyumba cya generator;

.Kandi bitatu 6000A byihuta cyane byahinduwe byakiriye gahunda yikizamini kandi byanze bikunze byahagaritse gufunga.Bisi ya 5000A yakoreshejwe, kandi buri generator yashizwe hamwe na busbar.Nyuma yo kugenzura guhuza, 2500A ya voltage ntoya yarafunzwe;Nyuma yo gufunga, amashanyarazi yashizwemo ikizamini cyuzuye.Ikizamini kimaze kurangira, generator yashizeho mbere ikuraho umuvuduko mubi ningendo zo kurangiza ikizamini (urugendo rwa mbere 2500A ya voltage ntoya -3200A ya voltage ntoya -600A ya voltage nini);

.Kugeza imbaraga zingenzi zagaruwe, generator yashizeho ihuza hamwe nimbaraga nyamukuru munsi yumutwaro.Nyuma ya gride ihuza, imashini itanga amashanyarazi ikurwaho kandi igasohoka, kandi uyikoresha ntabwo yumva ingaruka zigihe gito zumuriro wamashanyarazi cyangwa guhinduranya inzira zose;
