Kuyerekeza zabwino ndi kuipa kwa mndandanda inverter magetsi ndi parallel inverter magetsi:
1. Zigawo zazikulu ndi miyezo | |||
Nambala ya siriyo | dzina | Series resonant inverter wapakatikati pafupipafupi magetsi | Parallel resonance inverter wapakatikati pafupipafupi magetsi |
1 | Mphamvu za Mphamvu | Mphamvu yanthawi zonse 0.98 | Mphamvu yamagetsi ndi 0.7-0.92, ngati mphamvu yapakati sifika 0.90, Electric Power Bureau idzalipira chindapusa. |
2 | Kusungunuka kwamagetsi | 550±5% kW.h/t (1600 ℃) | ≤620±5% kW.h/t (1600℃) |
3 | Njira ya resonance | Mphamvu yamagetsi, kutayika kwa mzere wochepa (mkuwa wamkuwa ndi mphete ya ng’anjo) | Resonance yamakono, mzere (mkuwa ndi mphete ya ng’anjo) kutaya kwakukulu |
4 | zachuma | Ma harmonics otsika, kuwonongeka kochepa kwa gridi yamagetsi | High harmonics, kuipitsa kwakukulu kwa gridi yamagetsi |
5 | Mulingo woyambira bwino | Mphamvu imasinthidwa ndikusintha ma frequency a inverter, kotero kuti kuchuluka koyambira kumakhala kwakukulu. 100% chiwongola dzanja choyambira | N’zovuta kuyambitsa chipangizo pansi pa katundu wolemera |
6 | imayenera | Kuchita bwino kwambiri kumatha kukhala 10% -20% kuposa mphamvu yofananira | Kuchita bwino pang’ono chifukwa cha mphamvu zochepa komanso kuipitsidwa kwakukulu kwa harmonic |
7 | Yosavuta kugwiritsa ntchito | Series resonant magetsi amatha kuzindikira imodzi-kwa-imodzi, imodzi-kuwiri, imodzi-mpaka-tatu ntchito modes | Parallel resonant magetsi amatha kukwaniritsa ntchito imodzi ndi imodzi. |
8 | kuteteza | Malizitsani chitetezo ntchito | Pafupifupi ntchito zonse zachitetezo |
9 | Ndalama zakuthupi | Mtengo wazinthu ndi wokwera, chowongolera chimawonjezera capacitor ya fyuluta, ndipo magawo a gawo la voltage resonance amasankhidwa ndimitengo yayikulu. | Mtengo wazinthu ndi wotsika, wokonzanso safunikira kukulitsa capacitor ya fyuluta, ndipo magawo apano a resonance amasankhidwa ndi otsika. |
Kufotokozera: 1. Mphamvu yamagetsi
Mndandanda wa resonance power factor ndi wapamwamba: ≥0.98, chifukwa ma thyristors onse a gawo lokonzanso magetsi amakhala otseguka, ndipo dera lowongolera nthawi zonse limakhala lochita bwino. Kuwonjezeka mphamvu zimatheka ndi kusintha voteji wa mndandanda inverter mlatho. Choncho, mu ntchito yonse yogwira ntchito (kuphatikizapo mphamvu yochepa, mphamvu yapakati, mphamvu yapamwamba) ikhoza kuonetsetsa kuti zipangizozo zakhala zikuyenda bwino.
Parallel resonance power factor is low: ≤0.92, chifukwa ma thyristors onse a rectifier gawo la magetsi ali mu semi-open state (malipiro owonjezera amafunikira malinga ndi zofunikira za gridi ya dziko). , Mphamvu yamagetsi yamagetsi ndiyotsika kwambiri, nthawi zambiri 40% -80%; ma harmonics apamwamba ndi aakulu kwambiri, omwe amasokoneza kwambiri gridi yamagetsi.
