Kugwiritsa ntchito ma frequency apamwamba a DC magetsi

Magetsi amagetsi apamwamba kwambiri a DC amachokera ku ma IGBT apamwamba kwambiri omwe amatumizidwa kunja monga chida chachikulu chamagetsi, ndi ultra-microcrystalline (yomwe imadziwikanso kuti nanocrystalline) yofewa ya maginito alloy monga chigawo chachikulu cha thiransifoma.Dongosolo lalikulu lowongolera limatenga ukadaulo wowongolera maulendo angapo, ndipo mawonekedwe ake ndi umboni wa mchere, miyeso ya acidification ya chifunga.Mphamvu yamagetsi imakhala ndi dongosolo loyenera komanso lodalirika kwambiri.Mphamvu yamtunduwu yakhala chinthu chosinthidwa chamagetsi a SCR chifukwa cha kukula kwake kochepa, kulemera kwake, kuchita bwino kwambiri komanso kudalirika kwambiri.

Amagwiritsidwa ntchito kwambiri m'mafakitale akuluakulu amagetsi, ma hydropower, ma Ultra-high voltage substations, malo osayang'aniridwa monga kuwongolera, chizindikiro, chitetezo, kutsekanso, kuyatsa mwadzidzidzi, pampu yamafuta a DC, kuyesa, makutidwe ndi okosijeni, electrolysis, plating ya zinki, kupaka faifi tambala, malata plating, Chrome plating, photoelectric, smelting, mankhwala kutembenuka, dzimbiri ndi mwatsatanetsatane malo mankhwala pamwamba.Mu anodizing, vacuum coating, electrolysis, electrophoresis, kuthira madzi, kukalamba kwazinthu zamagetsi, kutentha kwamagetsi, electrochemistry, etc., imakondedwanso ndi ogwiritsa ntchito ambiri.Makamaka m'mafakitale a electroplating ndi electrolysis, chakhala chisankho choyamba kwa makasitomala ambiri.

Zofunikira zazikulu:

1. Kukula kochepa ndi kulemera kochepa:

Voliyumu ndi kulemera kwake ndi 1 / 5-1 / 10 yamagetsi a SCR, omwe ndi abwino kwa inu kukonzekera, kukulitsa, kusuntha, kusamalira ndi kukhazikitsa.

2. Mawonekedwe ozungulira ndi osinthika komanso osiyanasiyana, ndipo amatha kugawidwa m'lifupi-wosinthidwa, ma frequency-modulated, amodzi-omaliza komanso awiri.Magetsi amagetsi amtundu wa DC omwe ali ndi mawonekedwe ogwiritsira ntchito amatha kupangidwa molingana ndi momwe zilili.

3. Zabwino zopulumutsa mphamvu:

Kusintha magetsi kumatengera ma frequency apamwamba kwambiri, kutembenuka kwachangu kumakhala bwino kwambiri.Munthawi yanthawi zonse, magwiridwe antchito ndi apamwamba kuposa zida za SCR zopitilira 10%, ndipo kuchuluka kwa katundu kukakhala pansi pa 70%, kugwira ntchito bwino kumakhala kwakukulu kuposa zida za SCR zopitilira 30%.

4. Kukhazikika kwapamwamba:

Chifukwa cha liwiro la kuyankha mwachangu kwa dongosolo (mlingo wa microsecond), limakhala ndi kusinthika kwamphamvu pamagetsi amtaneti ndi kusintha kwa katundu, ndipo kulondola kwake kumatha kukhala bwino kuposa 1%.Mphamvu yosinthira imakhala ndi magwiridwe antchito apamwamba, kotero kuwongolera kuwongolera ndikwapamwamba, komwe kumapindulitsa kuwongolera mtundu wazinthu.

5. Mawonekedwe a ma wave wave ndi osavuta kuwongolera:

Chifukwa cha kuchuluka kwa magwiridwe antchito, mtengo wachibale wosinthira kusintha kwa ma waveform ndiwotsika kwambiri, ndipo mawonekedwe otulutsa amatha kusinthidwa mosavuta malinga ndi zosowa za ogwiritsa ntchito.Izi zimakhudza kwambiri kukonza magwiridwe antchito a malo ogwirira ntchito komanso kukonza zinthu zomwe zakonzedwa.
