Katundu Katundu Amagwiritsidwa ntchito kwambiri posungunula ndi kutenthetsa zitsulo zopanda ferrous ndi ferrous.Monga chitsulo chosungunula mu smelters, zitsulo wamba, mbale zitsulo zosapanga dzimbiri, aloyi zitsulo, mkuwa, zotayidwa, golide, siliva ndi zotayidwa aloyi, etc.;Zitsulo ndi mkuwa mbali ya diathermy forging, aluminiyamu ingots kwa akamaumba extrusion, etc. Chitani quenching ndi kutentha mankhwala monga kutentha kutentha ndi kutentha mankhwala pa zipangizo zitsulo.Chida chotenthetsera ng'anjo yapakatikati ndi yaying'ono, yopepuka kulemera, yogwira bwino kwambiri, yabwino kwambiri pakuwongolera matenthedwe, komanso yabwino ku chilengedwe.Ndi m'badwo wotsatira wa zida zotenthetsera zitsulo zochotsa mwachangu ng'anjo za malasha, ng'anjo za gasi, ng'anjo zamafuta, ndi ng'anjo wamba zosakanizidwa.
Katundu harmonic makhalidwe;ng'anjo zapakatikati zosungunula zimagwiritsidwa ntchito kwambiri posungunula, kuponyera ndi mafakitale ena.Komabe, pogwira ntchito, ng'anjo yamagetsi yapakati pafupipafupi imatenga ukadaulo wowongolera komanso inverter, zomwe zimapangitsa kuti pakhale ma harmonics apano ndi ma voltage.Kuwonongeka kwa Harmonic pamakina opangira magetsi kumapangitsa zida zolondola kugwira ntchito pakalakwitsa ndikuwonjezera kutayika kwa zida zamagetsi.Dongosolo lamagetsi la ng'anjo yapakatikati ya ng'anjo yapakatikati ndi gwero lalikulu kwambiri lamagetsi pamagetsi opangira magetsi, ndipo nthawi zambiri pamakhala magetsi osinthira ma ng'anjo apakati pafupipafupi komanso ng'anjo zoyatsira ma frequency apamwamba.Nthawi zambiri, ng'anjo 6 zokhala ndi ma single-pulse intermediate frequency induction makamaka zimapanga ma harmonics a 5, 7, 11, ndi 13 nthawi.Kwa 12 single-pulse converter intermediate frequency induction ng'anjo, ma harmonics ofunikira ndi 11, 13, 23 ndi 25th ma harmonics.Nthawi zambiri, ma pulse 6 amagwiritsidwa ntchito pazida zazing'ono zosinthira, ma pulse 12 amagwiritsidwa ntchito pazida zazikulu zosinthira, monga Y/△/Y mtundu wa ng'anjo yamoto, kapena 2 zosinthira ng'anjo zimagwiritsidwa ntchito popangira magetsi.
Malinga ndi mavuto omwe amakumana nawo muzochita zenizeni, chinyezi cha harmonic cha ng'anjo yapakatikati ndi yochepera 85%, koma makina osungiramo zinthu amalamulidwa kwambiri ndi ma harmonics, kusintha kwa ma harmonics kumatha kunyalanyazidwa, ndipo mphamvu yopulumutsa mphamvu ndi osakhutiritsa.Choyipa kwambiri ndichakuti mphamvu ya harmonic imaposa zida zololeza zopulumutsa mphamvu komanso zoteteza zachilengedwe, ndipo ndizosavuta kuwonongeka pakagwiritsidwa ntchito nthawi yayitali, ndipo ngozi zimachitika pafupipafupi.Chifukwa chake, poyankha chikhumbo chofulumira cha zinthu zambiri zomaliza, kuteteza chilengedwe ndi kupulumutsa mphamvu kwa ng'anjo zapakati pafupipafupi zakhala vuto lanthawi yayitali mumakampani opanga mphamvu, zomwe zimasokoneza mafakitale ndi mabizinesi ambiri.
1. Ng'anjo yapakati yapakati imapanga ma harmonics ambiri pakagwiritsidwe ntchito, ndipo kuwonongeka kwa harmonic mu gululi yamagetsi kumakhala koopsa kwambiri.
2. Ma Harmonics achepetsa mphamvu yotumizira ndi kugwiritsa ntchito mphamvu, kutenthetsa zida zamagetsi, kupanga kugwedezeka ndi phokoso, kuwononga kutsekeka, kuchepetsa moyo, ngakhale kusagwira ntchito ndi kupsa.
3. Ma Harmonics apangitsa kuti ma resonance am'deralo azimveka komanso kumveka kwadongosolo lamagetsi,
4. Kukulitsa zili harmonic, kuwotcha capacitance chipukuta misozi zida ndi zipangizo zina;
5. Ma Harmonics amayambitsa chitetezo cha relay ndi kuwonongeka kwa chipangizo;
5. Kunja kwa mphamvu zamagetsi, ma harmonics amasokoneza kwambiri zipangizo zoyankhulirana ndi zipangizo zamagetsi.
6. Ngati mphamvu yamagetsi sichikugwirizana ndi malamulo a 0.90 a ofesi yamagetsi, chilango chowongolera ndalama za magetsi chidzaperekedwa.
7. Mphamvu yotsika ya ng'anjo yopangira mafupipafupi komanso kuchuluka kwa katundu wokhazikika woperekedwa ndi thiransifoma yapadera kumawonjezera kulemetsa kwa transformer.
8. Palinso zinthu zina: mphamvu yamagetsi ya ng'anjo yapakatikati yamakasitomala yamakasitomala sakhala yotsika akamayikidwa, ndipo amangofunika kuwongolera mayendedwe apano.
Chifukwa chake, kuwongolera mphamvu ya ng'anjo yapakati pafupipafupi kwakhala chinsinsi chakuyankhidwa.Mayankho omwe mungasankhe:
plan 1
Kasamalidwe kapakati (ikani zosefera za harmonic m'chipinda chogawa magetsi choyenera kugwira ntchito nthawi imodzi ya ng'anjo zamagetsi zamagetsi zingapo zapakati)
1. Gwiritsani ntchito nthambi yolamulira ya harmonic (5, 7, 11 fyuluta) + nthambi yoyendetsera mphamvu yogwira ntchito.Chida cholipirira chosefera chikayamba kugwira ntchito, chiwongolero cha harmonic ndi kubwezeranso mphamvu kwamagetsi amakwaniritsa zofunikira.
2. Adopt yogwira fyuluta (chotsani dongosolo la ma harmonics amphamvu) ndi harmonic countermeasure nthambi dera (5, 7, 11 dongosolo fyuluta) # + chosayenera kusintha nthambi dera, ndipo mutatha kupereka kwa fyuluta zida chipukuta misozi, perekani patsogolo Pempho la chipukuta misozi cholakwika cha dongosolo lamagetsi.
Nkhani 2
Kuwongolera pamalo (khazikitsani chipangizo chosefera chapamwamba kwambiri pamalopo pafupi ndi gulu lamagetsi la ng'anjo yapakati)
1. Adopt anti-harmonic bypass (5th, 7th, 11th fyuluta), tsatirani basi ntchito ya ng'anjo yapakati pafupipafupi, thetsani ma harmonics pamalopo, ndipo musakhudze magwiridwe antchito a zida zina panthawi yopanga, ndipo ma harmonics samafika. muyezo utatha kugwiritsidwa ntchito.
2. Adopt yogwira fyuluta (bandwidth adjustment unit) ndi fyuluta bypass circuit (5th, 7th fyuluta), ma harmonics apamwamba pambuyo poyatsa samafika pa benchmark.
Njira 3:
Zosefera zathu zapamwamba zobwerezabwereza zamphamvu kwambiri zogwiritsa ntchito mphamvu.Mphamvu yathu ya Hongyan APF yoyima yokha ili ndi 100A, 200A, 300A, 500A ndi zina, ndipo mayunitsi 6 akhoza kufanana.Imayendetsa mgwirizano wa ma frequency awiri awiri.
