Kusakaniza kwa maginito kungathe kusakaniza bwino kusungunuka kwa aluminiyamu popanda kukhudzana, kusintha kapangidwe ka mankhwala ndi kutentha kwa kusungunuka, kuchepetsa kupangika kwa oxide slag, kufupikitsa nthawi yosungunula, kukulitsa zokolola, komanso kuchepetsa kwambiri mphamvu ya ogwira ntchito. Chifukwa cha zabwino zambiri za kusakaniza kwa maginito, chosakaniza cha maginito chakhala chida chofunikira kwambiri mumakampani osungunula ndi kuponyera aluminiyamu.

Kusakaniza kwa maginito kungathe kusakaniza bwino kusungunuka kwa aluminiyamu popanda kukhudzana, kusintha kapangidwe ka mankhwala ndi kutentha kwa kusungunuka, kuchepetsa kupangika kwa oxide slag, kufupikitsa nthawi yosungunula, kukulitsa zokolola, komanso kuchepetsa kwambiri mphamvu ya ogwira ntchito. Chifukwa cha zabwino zambiri za kusakaniza kwa maginito, chosakaniza cha maginito chakhala chida chofunikira kwambiri mumakampani osungunula ndi kuponyera aluminiyamu.

Chosakaniza chamagetsi chimapangidwa makamaka ndi magetsi osinthasintha komanso chotulutsira mpweya. Mphamvu yosinthasintha imasintha mphamvu ya 50/60Hz kukhala magetsi otsika a magawo atatu okhala ndi ma frequency a 0.5 ~ 5Hz. Mphamvu yamagetsi ikalumikizidwa ku coil ya inductor, mphamvu yamagetsi yoyendayenda imapangidwa. Mphamvu yamagetsi yoyendayenda imalowa mu mbale yachitsulo chosapanga dzimbiri pansi pa ng'anjo ndi mkati mwa ng'anjo ndikugwira ntchito pa aluminiyamu yosungunuka, kotero kuti aluminiyamu yosungunuka imayenda nthawi zonse, kuti ikwaniritse cholinga chosakaniza. Kukula ndi komwe mphamvu yosakaniza imatha kusinthidwa posintha magetsi, ma frequency ndi gawo la magetsi osinthasintha.

Mphamvu yaposachedwa ya AC, DC, AC yokhala ndi ufulu wodziyimira pawokha wa chidziwitso yopangidwa ndi HuateKampani ndi Yunivesite ya Nankai, Yunivesite ya Shandong ndi makoleji ndi mayunivesite ena, amapangidwa ndi kabati yowongolera ndi kabati yamagetsi yosinthasintha kuti apange dongosolo loyendetsa magetsi lamagetsi.

Ukadaulo waposachedwa wa PWM control umaswa kapangidwe kogwirizana ka chosinthira ma frequency kale. Malinga ndi mawonekedwe a katundu wa electromagnetic stirrer, kapangidwe kapadera ka mapulogalamu ndi zida kumachitika. Imatha kunyamula katundu waukulu wopangira popanda kuwonjezera kufananiza kwa impedance pakati pa magetsi ndi katundu, ndipo imatha kugwira ntchito pama frequency otsika. Ntchito yokhazikika. Mphamvu yaposachedwa ya PWM variable frequency ndiyoyenera kugwiritsidwa ntchito pa electromagnetic stirrers; poyerekeza ndi mphamvu yachikhalidwe ya variable frequency, mphamvu yaposachedwa ya PWM variable frequency ya Huateali ndi makhalidwe awa:

1. Mphamvu: Mphamvu yamagetsi yamagetsi atsopano a AC-DC-AC variable frequency imatha kufika pa 0.95, zomwe zimagwirizana mokwanira ndi malamulo adziko lonse a ma circuits amphamvu a magawo atatu (0.9-1). 0.95 kapena kuposerapo ndiye yabwino kwambiri. Ngati mphamvu yamagetsi ili yokwera kwambiri, magetsi adzakhala okwera kwambiri. Poyerekeza ndi mphamvu yamagetsi ya kapangidwe ka AC-AC, mphamvu yoyikidwa ya chipangizocho imatha kuchepetsedwa kwambiri.

2. Kutayika kwa ntchito kosasinthasintha: Mbali yokonzanso ya mphamvu yaposachedwa ya PWM AC-DC-AC variable frequency power supply sikufuna dera lowongolera lovuta, zida zokha zimataya pang'ono, ndipo mphamvu yosinthira imakhala yokwera kuposa ya dera lachikhalidwe la PWM. Zipangizo zikamayima, mphamvu yachikhalidwe ya frequency variable frequency imafunika kusinthana mphamvu yayikulu ndi gridi yamagetsi kuti isunge bata la DC bus, pomwe mphamvu yaposachedwa ya PWM variable frequency power supply ilibe kusinthana mphamvu ndi gridi yamagetsi. Ponena za mphamvu yotsika kuposa yachikhalidwe.

3. Kutayika kwa ntchito: Popeza choyambitsa ndi katundu woyambitsa, osati katundu wamtundu wa mota, palibe njira yosinthira kuchokera ku mphamvu yamakina kupita ku mphamvu yamagetsi, kotero palibe mphamvu yobwezera mphamvu panthawi yogwira ntchito. Mphamvu yatsopano ya PWM imazindikira kusinthana kwa mphamvu yosinthika ndi katundu woyambitsa kudzera mu capacitor yapakati yayikulu ya DC, chosungira mphamvu chokha ndicho chofunikira, ndipo palibe kusintha kwa mphamvu, Chifukwa chake, magetsi aposachedwa a PWM ali ndi zotayika zochepa zogwirira ntchito kuposa magetsi achikhalidwe osinthika.

4. Magetsi amagetsi: Popeza mphamvu yamagetsi ya PWM yosinthasintha imapangidwa ndi zida zamagetsi zamagetsi ndipo imasinthidwa ndi ma frequency okwera, mphamvu yamagetsi yachikhalidwe ya ma frequency osinthasintha imakhala ndi magawo awiri: PWM rectifier ndi PWM inverter. PWM rectifier yoyesedwa ndi gridi yamagetsi imapanga ma harmonics ambiri apamwamba ikagwira ntchito. Ngakhale kusefa kwa LC kumagwiritsidwa ntchito kumbali ya gridi, kumayambitsabe kusokoneza kwa ma radiation ku gridi ndi zida zozungulira; mphamvu yamagetsi yaposachedwa ya PWM ilibe kusintha kwa ma frequency apamwamba kumbali ya gridi, ndipo Pogwiritsa ntchito kusefa kwa LC kwa magawo ambiri ndi kusiyanitsa kwa transformer, mayesowa akuwonetsa kuti kusokoneza kwa ma radiation kumbali ya gridi ndi kochepa kwambiri, ndipo kumagonjetsanso mphamvu ya dziko lakunja pamagetsi oyambitsa ma electromagnetic.

5. Kukhazikika kwa zida: mphamvu yaposachedwa ya PWM variable frequency, mbali yokonzanso imagwiritsa ntchito njira yowongolera yosalamulirika ya kusintha kwachilengedwe, palibe dera lowongolera lovuta lomwe likufunika, ndipo derali ndi losavuta. Kuphatikiza apo, chifukwa chogwiritsa ntchito ma circuits angapo oteteza, kuphatikiza kuzindikira mzere wolowera, DC capacitor braking unit, kutentha kwa madzi, kuthamanga kwa madzi, ndi zina zotero, makamaka chitetezo chambiri cha IGBT, zimapangitsa kuti dongosololi ligwire ntchito modalirika, ndipo mawonekedwe ake apamwamba, kukhwima ndi kukhazikika kwake ndizodziwikiratu.

Chosakaniza chamagetsi chopangidwa ndi Huate chili ndi makasitomala apakhomo oposa 200, ndipo chatumizidwa kumayiko ndi madera opitilira khumi monga Brazil, Thailand ndi India, ndipo chayamikiridwa kwambiri ndi makasitomala.

Shandong Huate Magnetoelectric Technology Co., Ltd. idakhazikitsidwa mu 1993 (khodi ya stock: 831387). Kampaniyi ndi kampani yopanga zinthu payekha padziko lonse, kampani yapadera, yapadera, komanso yatsopano ya "giant" pamlingo wadziko lonse, kampani yatsopano padziko lonse, komanso kampani yatsopano padziko lonse. Ndi kampani yofunika kwambiri yaukadaulo wapamwamba, kampani yowonetsera chuma chanzeru padziko lonse, kampani yotsogola mu Linqu magnetoelectric equipment yomwe imadziwika ndi National Torch Program, wapampando wa National Magnetoelectric and Low Temperature Superconducting Application Technology Innovation Strategic Alliance, komanso wapampando wachiwiri wa China Heavy Machinery Industry Association. Pali malo ogwirira ntchito ofufuza zasayansi pambuyo pa udokotala padziko lonse, malo ogwirira ntchito ophunzirira, malo ogwirira ntchito ofunikira a chigawo chaukadaulo wamagetsi ndi zida, komanso malo ogwirira ntchito aukadaulo wamagetsi ndi zamagetsi m'chigawo ndi nsanja zina za R&D. Pokhala ndi malo okwana 270,000 sqm, ili ndi chuma choposa 600 miliyoni yuan ndi antchito oposa 800. Ndi imodzi mwa malo akuluakulu opangira ndi kupanga zida zamaginito ku China. Yodziwika bwino popanga zithunzi za maginito zogwiritsa ntchito maginito, maginito okhazikika, maginito ogwiritsira ntchito maginito ogwiritsira ntchito maginito ndi kutentha kochepa, olekanitsa chitsulo, zida zonse za migodi, maginito osakaniza, ndi zina zotero, ntchito yogwirira ntchitoyi imakhudza migodi, malasha, mphamvu yamagetsi, zitsulo, zitsulo zopanda chitsulo ndi malo azachipatala, zomwe zimagulitsidwa ku Australia, Germany, Brazil, India, South Africa ndi mayiko opitilira 30.
