Kodi ndi zinthu ziti zomwe zimabweretsa phokoso lachilendo mu ma transfoma othamanga kwambiri?

Ma transfoma othamanga kwambiri nthawi zina amapanga phokoso panthawi yogwira ntchito, ndipo chimodzi mwa zifukwa za izi ndi kuzizira. Chifukwa zimakupiza zimapanga phokoso, khutu la munthu ndilomveka kwambiri ku harmonic ya burodibandiyi kuposa ma harmonics opangidwa ndi ma frequency apakati. Kuthamanga kwakukulu kumadalira zinthu zambiri, kuphatikizapo kuthamanga kwa mafani, kuchuluka kwa masamba ndi mawonekedwe a tsamba. Mphamvu yamphamvu yamawu imadalira kuchuluka kwa mafani komanso liwiro.

Mofanana ndi makina a phokoso la thupi la transformer high-frequency, phokoso la chipangizo chozizira limayambanso chifukwa cha kugwedezeka kwawo, ndipo gwero la kugwedezeka kwake ndi:

1. Kugwedezeka kopangidwa ndi fani yoziziritsa ndi pampu yamafuta panthawi yogwira ntchito;

2. Kugwedezeka kwa thupi la transformer lapamwamba kwambiri kumaperekedwa ku chipangizo chozizira pogwiritsa ntchito mafuta otsekemera, ophatikizana ndi mapaipi ndi zigawo zawo zosonkhana, zomwe zimakulitsa kugwedezeka kwa chipangizo chozizira ndikuwonjezera phokoso.

Kuonjezera apo, pachimake chikatenthedwa, chifukwa cha kusintha kwafupipafupi komanso kupanikizika kwa makina, phokoso lake lidzawonjezeka ndi kuwonjezeka kwa kutentha. Chilengedwe cha malo ogwirira ntchito (monga makoma ozungulira, nyumba ndi maziko oyika, etc.) amakhudzanso phokoso. Kwa ma transformer ambiri amphamvu oziziritsa mphepo, chowotcha chozizira ndi gwero laphokoso lodziwikiratu kuposa thiransifomayo.

Zomwe zimayambitsa phokoso lachilendo ndi chiyanima transfoma apamwamba kwambiri?

Potengera njira yopangira ma transfoma apamwamba kwambiri, pali zinthu zingapo izi:

1. Kachulukidwe ka maginito a thiransifoma ndi okwera kwambiri, pafupi ndi machulukitsidwe, ndipo kutulutsa kwa maginito ndikokulirapo, komwe kumapangitsa phokoso;

2. Zomwe zili pachimake ndizosauka kwambiri, kutayika kumakhala kwakukulu, ndipo phokoso limapangidwa;

3. Zomwe zili ndi harmonic ndi gawo la DC mu dera logwira ntchito lidzachititsanso phokoso pachimake komanso ngakhale koyilo;

4. Njira yopangira thiransifoma:

a. Koyiloyo imavulazidwa kwambiri;

b. Koyilo ndi pachimake sizimakhazikika;

c. Pachimake sichimakhazikika;

d. Pali kusiyana kwa mpweya pakati pa EI, yomwe imapanga "buzzing" panthawi ya ntchito;

e. Mapepala awiri achitsulo a silicon kunja kwa E-mtundu wapakati samayendetsedwa bwino, zomwe zimakhala zosavuta kupanga phokoso;

f. Chithandizo cha dipping process: kuwongolera kukhuthala kwa utoto wotsekereza;

g. Zigawo zazitsulo (maginito) zomwe zili kunja kwa thiransifoma sizikhazikika;

5. Ngati ndi chinthu chokwera kwambiri, padzakhala phokoso ngati kutsekemera sikukuyendetsedwa bwino.

●Zhongshan XuanGe Electronics ndi fakitale yomwe imagwira ntchito kwambiri popanga ma transfoma othamanga kwambiri,ma inductors, zoseferandi zida zina zamagetsi, zokhala ndi zaka 15 zopanga.
● Kampaniyo yakumana ndi akatswiri opanga ma skeleton design engineers, core design engineers, transformer development engineers ndi ena ogwira ntchito zaluso ndi magulu a R&D, omwe amatha kusinthidwa malinga ndi zofunikira za kasitomala kuti akwaniritse zosowa za makasitomala osiyanasiyana.
