Mfundo zoyika za 250KW Yuchai Genset ndi UPS

Choyamba, tiyenera kumvetsetsa zambiri za katunduyo momwe tingathere, ndipo pazifukwa izi, moyenerera kukulitsa mphamvu yotulutsa jenereta.Pansi pamalingaliro awa, zidzakhala zopindulitsa kwambiri kuti jenereta yokhazikitsidwa ifike 60% ~ 80% kuchuluka kwa katundu momwe ndingathere.

Yesani kusankha jenereta yokhala ndi zoletsa zotsika komanso kuthekera koyankha kwakanthawi;Ndibwino kuti mugwiritse ntchito mtundu womwe umakhudzidwa kwambiri ndi ma harmonics, monga jenereta ya maginito ya PMG.

Kuti muzindikire voteji ya jenereta ya AVR, tikulimbikitsidwa kugwiritsa ntchito kuzindikira kwa magawo atatu kuti mutenge mtengo wapakati m'malo mozindikira gawo limodzi, kuti mupititse patsogolo kukhazikika kwa kuzindikira kwamagetsi ndikuchepetsa kusinthasintha kwamagetsi pa jenereta.Ma jenereta okhala ndi mitundu yosiyanasiyana yogwirira ntchito amakhala ndi zotsatira zopanda mzere.Kuchuluka kwa katundu kudzakhalanso kosiyana.Mwachitsanzo, awiri sitiroko dizilo seti yabwino kuposa anayi sitiroko dizilo seti.Kuyenera kudziŵika kuti ngati chizindikiro kolowera wa generator set controller sizolondola, zipangitsanso kusagwirizana ndi UPS.Panthawi yotumiza UPS, ngati mtengo wamagetsi a jenereta ndi ma frequency counter apezeka kuti ndi osakhazikika, kuchepetsa bwino kondomu ya AVR kumatha kuthetsa vutoli.

Pofuna kupewa chizindikiro chosokoneza cha AC kuti chisakhudze magwiridwe antchito a kazembe wamagetsi a injini, nyumba ya abwanamkubwa iyenera kukhala yokhazikika bwino ndipo njira zodzitetezera ziyenera kuchitidwa kuti zizindikiritse liwiro.Ndikofunikira kuti jeneretayo iperekedwe pang'onopang'ono komanso motsatizana.M'malo mwake, katundu wolemetsa amayamba koyamba ndipo zopepuka zimayamba pambuyo pake.

Kachiwiri, mphamvu yogwira yofalitsidwa ndi jenereta imatengera mphamvu ya injini, ndipo mphamvu yowonekera makamaka imadalira mphamvu ya jenereta.Choncho, pamene jenereta seti okonzeka ndi katundu nonlinear monga inverter, yekha mphamvu jenereta ayenera kuonjezeredwa, ndipo makhalidwe ake osakhalitsa adzakhala bwino kwambiri, pamene linanena bungwe mphamvu yogwira gulu n sichikuwonjezera Practice watsimikizira kuti ndizotheka kuthetsa vuto lofananira la inverter ndi jenereta yokhazikitsidwa pogwiritsa ntchito galimoto yokoka pony iyi, ndipo imatha kupulumutsa ndalama zina kwa ogwiritsa ntchito, ndipo ndalamazo ndizochulukirapo.

Chachitatu, kuti musankhe inverter yoyenera kwambiri pamakhalidwe a jenereta, inverter yokhala ndi mphamvu yayikulu yolowera ndi ma harmonic otsika ayenera kusankhidwa.Kwa fyuluta, mbali yolowera ya UPS imakhala yogwira mtima pamene UPS ilibe katundu kapena katundu wopepuka.Makhalidwe, tikulimbikitsidwa kuti tisankhe mitundu yomwe ingapereke njira zowongolerera ndikuwongolera.Ngati inverter ili ndi ntchito ndi mawonekedwe a liwiro lalikulu la Broadband rectifier control circuit, bypass voltage, frequency protection range, pa site adjustable inverter synchronization rate, kuchedwetsedwa koyambira kuyenda mkati, rectifier pang'onopang'ono, njira yanzeru ya jenereta, etc., akhoza kufananiza bwino ndi jenereta.

Chachinayi, pakugawa kwamagetsi otsika, mawonekedwe owonjezera a inductive katundu ndi capacitive katundu angagwiritsidwe ntchito kusunga mphamvu ya inductive ya katundu wonse pafupifupi 0.9 momwe angathere;Makina osinthira okha, omwe amatha kulumikiza katundu wolowetsa monga chowongolera mpweya kutsogolo kwa inverter.

Nthawi yosinthira yokha ya Mtengo wa ATS imagwedezeka kuti iteteze katundu wonse kuti ayambe nthawi yomweyo pamene mphamvu ya mains imadulidwa, zomwe zimapangitsa kusinthasintha kwakukulu kwa jenereta kapena kutsekedwa kwa chitetezo;Pewani zotakataka mphamvu chipukuta misozi ya seti jenereta;Owongolera okhwima komanso odalirika a chipukuta misozi amagwiritsidwa ntchito pobwezera, capacitive reactive power compensation ndi harmonic control in power system.

1. Malo oyikapo azikhala ndi mpweya wabwino, wokhala ndi mpweya wokwanira kumapeto kwa jenereta ndi mpweya wabwino kumapeto kwa injini ya dizilo.Dera lotulutsa mpweya liyenera kukhala lalikulu kuwirikiza nthawi 1.5 kuposa thanki yamadzi.

2. Malo ozungulira malo oyikapo azikhala aukhondo kuti asaike chilichonse chomwe chingatulutse mpweya ndi gasi.Ngati zinthu zilola, zida zozimitsira moto ziyenera kuperekedwa.

3. Mukagwiritsidwa ntchito m'nyumba, chitoliro chotulutsa mpweya chidzalumikizidwa ndi kunja.The awiri a chitoliro ayenera kukhala wamkulu kuposa kapena wofanana ndi awiri a muffler utsi chitoliro.Chiwerengero cha ziboliboli za chitoliro sichiyenera kupitirira 3 kuti zitsimikizire kutulutsa kosalala.Chitolirocho chiyenera kulumikizidwa ndi kupendekera kwa madigiri 5 mpaka 10 kuti mupewe jekeseni wamadzi amvula.Ngati chitoliro cha utsi chayikidwa chokwera pamwamba, chipangizo chopanda mvula chiyenera kuikidwa.

4. Mukamagwiritsa ntchito konkriti ngati maziko, kutsetsereka kwa chipangizocho kudzayesedwa ndi mlingo wa mlingo panthawi ya kukhazikitsa kuti mukonze chipangizocho pa maziko opingasa.Payenera kukhala pad shockproof pad kapena nangula pakati pa unit ndi maziko.

5. Chipolopolo cha unit chiyenera kukhala chokhazikika.Kwa jenereta yomwe imayenera kukhala yokhazikika yopanda ndale, malo osalowerera ndale ayenera kukhazikitsidwa ndi akatswiri komanso okhala ndi zida zoteteza mphezi.Ndizoletsedwa kuyendetsa malo osalowerera ndale ndi mains grounding chipangizo.Kutera molunjika.

6. Njira ziwiri zosinthira pakati pa jenereta ndi mphamvu zamagetsi ziyenera kukhala zodalirika kwambiri kuti ziteteze kufalikira kwa mphamvu.Kudalirika kwa njira ziwiri zosinthira mawaya kuyenera kuyang'aniridwa ndikuvomerezedwa ndi kampani yamagetsi yakumaloko.
