Poyankha kagwiritsidwe ntchito kaukadaulo waukadaulo watsopano pamaulendo apanjanji, eni eni aku China adaganizira kale momwe angapangire njira yatsopano yogwirira ntchito mwanzeru komanso kukonza mayendedwe a njanji kuti zitsimikizire kukhala zotetezeka, zobiriwira, zodalirika, zogwira ntchito kwambiri, komanso zotsika. -ndalama zoyendera zoyendera anthu akutawuni.
Sitima yapamtunda yothamanga kwambiri yamagetsi: imagwiritsa ntchito mphamvu yamagetsi yamagetsi, imatembenuza mphamvu yamagetsi kukhala mphamvu yamakina, ndikusunga mphamvu.Mphamvu yowunikira magetsi imapereka mphamvu zowunikira zosiyanasiyana, ma escalators, blowers, mapampu ndi zida zina zamakina amagetsi pamasiteshoni ndi magawo, komanso mphamvu yolumikizirana, ma sign, automation ndi zida zina.Kusintha kwamagetsi amagetsi opangira magetsi kumaphatikizapo malo ochepetsera kuthamanga kwa magazi komanso nyali zowunikira zamagetsi zamagetsi ndi zida zogawira nyali.
Dongosolo lamagetsi lomwe likufotokozedwa likufotokozedwa mwatsatanetsatane kuchokera pakuwona malo amkati, momwe zida zambiri zamagetsi zili pansi pa siteshoni iliyonse yogawa.AC ndi DC amatha kugawa zida zamagetsi mu AC system ndi DC system.
Ma Harmonics mu njanji yakutawuni makamaka amachokera ku traction belt power supply rectifier inverter unit, kutsatiridwa ndi magawo athunthu amagetsi a DC, kuyatsa, ma elevator, ma monitor, ma air conditioners, mapaipi a ngalande ndi zida zina.Ma harmonics ofunikira ndi ma harmonics a 5, 7, 11 ndi 13, ndi ma harmonics ena achitatu akuphatikizidwanso.Zosungira zosagwira bwino pamakina ogwiritsira ntchito ma harmonic apamwamba zimawonjezera kutayika kwa mizere, zimakhudza magwiridwe antchito odalirika achitetezo cholumikizirana ndi zowongolera zokha, ndikuchepetsa chitetezo chazida zamagetsi zomwe zimagwiritsidwa ntchito, potero kumapangitsa kusokoneza kwamagetsi pamalumikizidwe ndi ma siginecha.Ma Harmonics amathanso kukhala ndi zotsatira zowononga pazida zina zolipirira mphamvu zamagetsi pamzere.Panthawi imodzimodziyo, chipangizo chothandizira mphamvu zowonjezera chidzakulitsa ma harmonics, ndikupanga bwalo loipa.
Mtengo Wogwiritsa Ntchito Harmonic Governance
Sitima zapamtunda za m'tauni, makamaka njira yopangira magetsi ndi kugawa masiteshoni apansi panthaka, imafuna kudalirika kwambiri kwamagetsi.Pulse current ndiye chifukwa chachikulu chakuwopseza kudalirika kwamagetsi ake.Kugwiritsa ntchito zosefera zogwira ntchito kumatha kuwongolera ma harmonics, kuchepetsa kuvulaza kwa ma harmonics pamakina operekera magetsi ndi kugawa, ndikuwonetsetsa kuti njanji yamtawuni ikuyenda bwino komanso mokhazikika.Panthawi imodzimodziyo, pambuyo pa fyuluta ya harmonic, kutayika kwa harmonic kwa dongosolo kumachepetsedwa, ndipo chipangizo choyambirira cha capacitor chikhoza kugwiritsidwa ntchito mwachizolowezi, kuchepetsa kutayika kwa dongosolo.
Mavuto omwe mungakumane nawo?
1. Mphamvu yamagetsi ndi yotsika, ndipo chipangizo cholipirira champhamvu chokhazikika sichingagwire ntchito kapena chimawonongeka nthawi zambiri;
2. Kusintha kwa katundu
3. Kusinthasintha kwakukulu kwa mphamvu zamakono kumakhudza ntchito yodalirika ya chitetezo cha relay ndi zida zodzitetezera zokha;
4. Kusalinganika kwa magawo atatu a intaneti pamagetsi amagetsi ndikovuta.
Yankho lathu:
1. Pofuna kuchepetsa zomwe zili muzinthu zomveka bwino, chipangizo chosefera gwero chimayikidwa pa basi yachiwiri ya 400V ya siteshoni yotsika kuti isefa.
2. Kutengera mawonekedwe amphamvu a Hongyan mndandanda zotakasika zotakasika mphamvu jenereta kupereka mphamvu zotakasika gawo lililonse la dongosolo ndi kusamalira harmonics dongosolo pa nthawi yomweyo.
3. Sankhani Hongyan zazikulu chitetezo zida chipukuta misozi, moyenera kupanga capacitor ndi magawo angapo riyakitala magawo malinga ndi zimachitika panopa udindo wa dongosolo, kusintha mphamvu chinthu kudzera zotakasika chipukuta misozi mphamvu, ndi kusintha mphamvu khalidwe la m'tauni njanji magetsi ndi kugawa dongosolo.
4. Hongyan a mphamvu chitetezo chipukuta misozi zida utenga wosakanizidwa chipukuta misozi njira ya magawo atatu kulekana chipukuta misozi ndi magawo atatu co-chipukuta misozi, ndipo amaona zofunika chipukuta misozi ya magawo atatu unbalance dongosolo mapulogalamu.
