Kupanikizika kotsika kwa divelosel disction kusinthira kwa zovuta zambiri

Abrstract: Makonda otsika a volitor omwe ali ndi mwayi wosankha kwambiri kwa ogwiritsa ntchito ambiri, ndipo nthawi zambiri amatanthauza zomwe amagwiritsa ntchito 230v / 400V. Komabe, m'malo ena, chifukwa cha mtunda pakati pa senelsel enel ndi magetsi, madontho a m'manja amatha kuchitika, chifukwa cholephera kugwiritsa ntchito magetsi nthawi zonse, komanso kuwotcha zida zamagetsi. Chifukwa chake, kwa ogwiritsa ntchito omwe adagula kale zotsika kwambiri za dizilo, amatenga miyeso kuti ikhale yotsika kwambiri kuti ikhale yabwino kwambiri, kuti musatulutse jereta yotsika kwambiri, kuti isawonongeke pachuma.

1, kufanizira kwabwino ndi zovuta za zovuta komanso zochepa

1. Ubwino wa magetsi apamwamba kwambiri:

. Izi ndichifukwa choti, potulutsa mphamvu yomweyo, zamakono zopatsirana kwambiri zimatha kukhala zazing'ono kwambiri kuposa zomwe zimapangitsa jenereta yamagetsi. Kotero kuti kuwonongeka kwamphamvu kwambiri kumatha kugwiritsa ntchito ma wimer ang'onoang'ono. Zotsatira zake, cholembera chazomwe zimapangitsa kuti magetsi am'madzi azikhala ochepa kwambiri kuposa opanga magetsi ochepa. Kwa amitundu yambiri, mukamagwiritsa ntchito mphamvu zamagetsi ochepa, slot yayikulu kwambiri imafunikira chifukwa chosowa cha mawaya, zomwe zimapangitsa kukula kwakukulu kwa choyimira pachimake ndi voliyumu yayikulu;

. Makamaka opangira magetsi okwanira 10kv, amatha kugwiritsa ntchito magetsi a Gridi, omwe angachepetse ndalama mu zida zamagetsi, kugwiritsidwa ntchito mophweka, ndikuchepetsa wolephera.

2. Zovuta za magetsi okwera kwambiri

.

2, kukulitsa njira yopanga jenereta

Pamalo omwe amafunikira magetsi kwambiri, kuwonjezera pa kuperekedwa kwa genetirer generar-voltor enertor amapezeka ndi omasulira amathanso kugwiritsidwanso ntchito.

1. Ubwino wa voliyumu yotsika kuti ikhale yamphamvu kwambiri

.

. Popanda mzere wa zero, palibe chosinthira zero; Sinthani mahule omwe amapangidwa ndi katundu wosanjidwa ndi magetsi kumtunda kwa magetsi kuchokera kumbali ya magetsi kuchokera kumbali yamagetsi yotsika, ndikupangitsa kuti mbali yotsika kwambiri ikhale yoyera ndipo osakhudzanso ntchito ya magetsi osakhazikika (avr) mkati mwa jenereta, komanso kuthetsa Mavuto osiyanasiyana obwera chifukwa cha njira yosinthira zero;

. Kutumiza kwakukulu kumakhala ndi kuchuluka kwa mkuwa, ndipo chachikulu maginiki akuluakulu amagwira ntchito yovuta yobwezeretsa jenereta pompopompo.

2. Zovuta za kulumikizana komwe kumayenderana ndi mayunitsi am'madzi otsika

Mu mtundu wa 380-415Vac, ngati ma genereta angapo amalumikizidwa mofananamo mbali yotsika kwambiri kenako ndikuyenda ndi wosinthitsa wosinthira; Malire olimbikitsidwa ndi 7500 kva, 6000 kw. Mukapitilira malire apamwamba, zinthu zotsatirazi ziyenera kulingaliridwa: -

Kuthekera kwa malo otsika mabizinesi otsika ayenera kukhala pafupi ndi 10ka, poganizira luso la busbar kuti athe kupirira magetsi olakwika komanso chithandizo chamagetsi mkati mwa chiwongola dzanja chotsika kwambiri);

• Kutulutsa kwa magetsi othamanga (mpaka kupirira magetsi mapiri), monga kupitirira 65ka ndi 100ka;

• Ndikofunikira kuwerengera kaya chingwe cha Amperar Amperar, magetsi otsika kwambiri, ndipo mtengo wa m'manja ndi wololera;

3, kukonzanso mlandu

1. Mapangidwe a zida ndi magawo

Wogwiritsa: Ntchito ku Macau

● Kutumiza Magetsi: UPS + 6000Kva Jerereta

Kukula kwathunthu kwadzidzidzi: 4500kva, 3600kW

Makina a voliyumu: mphamvu yayikulu 11kv, 50hz ndi magetsi otsika 415 tchuthi

Mphamvu: 4 Kta50-GS8 Models / 1200kW Jenereta

Kugwira ntchito ku Generetor: 3 Main And 1 Sungani, ndi 1 yosungidwa. Mtundu uliwonse jenereta ikhoza kulumikizidwa ndi mphamvu yogwiritsira ntchito

Kupanga kwa jenereta kuyika magetsi: 415Vac / gawo la magawo atatu / 50

● Kusintha kochepa kwa voliyumu yopanda jenereser:

5000a Busbar / 80ka1 masekondi / magawo atatu a waya / 50

The 5000a Busbar imagawidwa magawo a ndi b

Gawo la Basibali limalumikizidwa ndi jenereta awiri, imodzi ndi awiri

Gawo b la busbar yolumikizidwa ndi jenereta awiri, 3 ndi 4

Kukhazikitsa kwa 5000a4 Porckenection Switch ya mabasi a basi a ndi b

○ 4 × 2500a Air Switch → Olumikizidwa ndi ma 4 jenereta

3 × 3200a Air Switch → olumikizidwa ndi ma transformers atatu (mbali yotsika kwambiri)

● Matembenuzidwe oyenda: 3 seti ya 2000kva11kv / 0.415KV

● Kusintha kwa magetsi kwambiri kwa Stevicer: Vacuum switch, 15kv600a → olumikizidwa ndi ma transformers atatu (magetsi apamwamba)

2. Kusanthula

(1) Magawo anayi a P1500 a P1500 amalumikizidwa ndi gululi kuti agwiritse ntchito, pogwiritsa ntchito magawo atatu + 1 ofanana. Mosasamala kanthu kuti ndi gawo liti lomwe limafunikira kukonza, sizikhudza magetsi adzidzidzi;

. -Voltage amasintha kuti apereke mphamvu kumadera osiyanasiyana;

. Fotokozani mosapita m'mbali zovuta zonyamula zida zoyaka, utsi utsi, ndi phokoso loyambitsidwa ndi jenereta;

. Ndipo ma 3000 a ma evani ambiri amalandila pulogalamu yoyeserera ndipo adathetsa mkati kuti atseke. The 5000babar inali yoyendetsedwa, ndipo jenereta iliyonse idalumikizidwa ndi busbar. Kutsegulira Kuyendera, kusintha kwa 2500a kotsika kwambiri kunatsekedwa; Pambuyo pa kutseka, jenereta yokhazikitsidwa ndi mayeso okwanira. Mayeso atamalizidwa, jenereta imakhazikitsidwa koyamba kuti amalize mayeso (paulendo woyamba wa 2500a otsika-voliyumu yotsika-voliyumu yotsika-voliyumu yotsika kwambiri);

. Mpaka mphamvu yamphamvu yobwezeretsedwa, jenereta imayikidwanso ndi mphamvu yolumikizidwa. Pambuyo polumikizana, jenereta yachotsedwa ndikuchotsedwa, ndipo wogwiritsa ntchito samamvanso kwakanthawi kwa mphamvu kapena kusintha konsekonse;
