CHII CHINONZI CHINHU CHINHU CHINHU CHESIMBA? INOSHANDA SEI?

Kushandura ma transformer kunodiwa mukushandura magetsi.Saka chii chinonzi switching transformers?Ndeapi misimboti yekushanda uye mabasa ekuchinja ma transformer?Ngativanzwisise.

 

·Nhanganyaya

Iyo switching transformer inoreva shanduko inoshandiswa mumagetsi ekuchinja.Inoshanda mu pulse state ine frequency yegumi kusvika makumi e kilohertz kana kunyange mazana e kilohertz.Iyo iron core inowanzo gadzirwa neye ferrite zvinhu.

           

·Kushanda musimboti wekuchinja transformer

Transformer chishandiso chemagetsi chinogadzirwa uchishandisa musimboti wemagetsi induction.Kana iyo yekutanga coil yetransformer yakabatana kune AC magetsi sosi, iyo musimboti wesimbi inoburitsa inochinjana magineti flux.Simba rekushandura magetsi rinodzorwa nedunhu, uye switch chubhu inoshanduka pakumhanya kukuru.

Kushandura yakananga ikozvino kune yakakwirira frequency alternating ikozvino inopihwa kune transformer yekushandura, nekudaro ichigadzira imwe kana akawanda seti yemagetsi.Sezvo kushanda kweiyo yakakwira frequency AC munharaunda yetransformer yakakwira zvakanyanya kupfuura 50Hz, zvese zvinoshandura zvinoshandura zvinogona kuitwa diki kwazvo, nekudaro kuderedza mutengo.

 

·Tiye basa rekuchinja transformers

Basa guru rekushandura kushandura magetsi kufambisa magetsi, kushandura magetsi uye kuvhara.

Mabhenefiti ayo makuru saizi diki, kushanda kwepamusoro, uye kutambanudza zvakachipa.Sechinhu chikuru chakapfava magineti emagetsi emagetsi, machinjiro ekuchinja anoshandiswa zvakanyanya mukuchinja magetsi emagetsi tekinoroji uye magetsi emagetsi tekinoroji, uye anoshandiswawo mumaseketi akakwira-frequency sekuchinja magetsi.

 

Zvinoenderana nesimba rekufambisa reiyo switching transformer, magetsi emagetsi anogona kukamurwa kuita mamakisi akati wandei: 10kVA isimba rakakura, 10kVA ~ 0.5kVA isimba repakati, 0.5kVA ~ 25VA ine simba shoma, uye pazasi 25VA idiki simba.Simba rekutumira rakasiyana, dhizaini yemagetsi transformer zvakare yakasiyana.Iyo ferrite musimboti uye magineti saturation coefficient yemagetsi transformer haina kunaka seiyo yesilicon simbi sheet sheet, zvichikonzera kushoma simba paHertz yeAC simba rekufambisa.Asi anoshanda munzvimbo yakakwirira-frequency circuit, uye simba rekutsinhanisa nguva pane imwe nguva yeyuniti yakakwira zvikuru (1000 nguva iyo yepasi-frequency transformer).Kutorwa pamwe chete, kushanda kwayo kunogona kusvika makumi enguva iyo yepasi-frequency transformers.

 

·Rimwe basa rekushandura transformer nderekuti ine mhinduro inotenderera

Mhedzisiro yemhinduro inopa chiratidzo chemhinduro yakanaka kuPWM IC, zvichiita kuti igadzire yakakwira-frequency oscillation pamwe neyechipiri mhepo, kuitira kuti iyo DC ichipinda mumhepo yekutanga yetransformer ine yakakura AC chikamu, uye yakakwirira-frequency AC. chikamu chakaparadzaniswa neiyo transformer core, ichigadzira yechipiri Pure high-frequency AC, iyo inogadziriswa uye inosefa kuti ipe michina yemagetsi.Mhedziso inotenderera inogona kugadzirisa inobuda voltage kune yakagadzikana kukosha.Kupfupisa, iyo switching transformer inotamba basa rekufambisa simba, kushandura voltage uye kuvharira.
