Dabeeto mawjad sine ah

Sharaxaad Gaaban:

U beddelaa shucaaca wax soo saarka mootada PWM hir sine ah oo simanIska yaree ifafaale dhawaaqa ka dhasha awood qaybsan iyo inductance la qaybiyey oo ay ugu wacan tahay dhererka fiilada, baabi'inta korantada matoorka ee ay keento dv/dt sare, baabi'inta dhaawaca degdega ah ee matoorka ee ay keento luminta hadda jirta, shaandhada ayaa yaraynaysa maqalka buuqa matoorka.

380V sine filter miiska xulashada alaabta caadiga ah

Odhaah

(1) Moodooyinka kor ku xusan waa badeecadaheena caadiga ah, iyo tilmaamo kale ayaa loo habeyn karaa iyadoo loo eegayo shuruudaha macaamiisha;
(2) Haddii aad u baahan tahay cabbirro gaar ah iyo qiimayaal inta lagu jiro xulashada moodalka, fadlan la tasho ganacsigeenna;
(3) Qiyaaso gaar ah iyo cabbirro, fadlan tixraac qeexitaannada iyo sawirrada ay bixiso shirkadeena wixii faahfaahin ah.
Tixgelinta xulashada shaandhaynta mawjada wabiga
1. Ka dib marka la isticmaalo shaandhada sine-wave, awoodda culeyska ee beddelka waxay noqon doontaa mid ka hooseysa awoodda culeyska culeyska soo noqnoqda ee matoorka.
2. Shaandheeyaha sine wave wuxuu keeni doonaa qayb go'an oo ah hoos u dhaca danabka ee danabka la sifeeyay.Inta jeer ee aasaasiga ah ee 50Hz, hoos u dhaca danabku waa qiyaastii 10%.Saamigoodu wuxuu u dhigmaa isbeddelka inta jeer ee aasaasiga ah.
3. Shaandheeyaha ayaa soo saara tiro badan oo ka mid ah qaybaha iswaafajinta ee nidaamka sare ee habka lagu sifeynayo mowjadda PWM ee mawjadda sinaha, sidaas darteed rogaha ayaa yeelan doona wax ku saabsan wax soo saarka hadda la qiimeeyay ee rookaha marka filtarku aanu culeys lahayn.
4. Kadib markaad isticmaasho shaandhada mawjada sine, dhererka siliga la isku xidhi karo waa 300m-1000m
5. Alaabta shaandhada sine wave ee caadiga ah, inta jeer ee wax-soo-saarka inverter-ku waa 4-8KHz.Haddii inta jeer ee sidaha codsigaagu aanu ku jirin xadkan, fadlan u sharax shirkadda.Haddii kale, isticmaalka shaandhada ayaa saameyn doonta, shaandhada ayaa guban doonta xaalado daran.
6. Shaandheeyaha waa inuu xaqiijiyaa hawo wanaagsan marka la isticmaalayo.

Qiyaasaha Farsamada

Astaamaha
Qaab dhismeedka dabaysha ee waxqabadka sare leh ayaa la qaatay, safka aluminiumka ayaa la soo saaray, kaas oo leh iska caabin yar oo DC ah, awood xoog leh oo ka hortagga elektromagnetic, iyo awood xad dhaaf ah oo waqti gaaban ah;Waxqabadka sare ee qalabka dahaadhka ee heerka Japan ayaa loo isticmaalaa si loo hubiyo in badeecada wali lagu sii hayn karo xaalado shaqo oo daran.Waxqabad la isku halayn karo;reactor-ku waxa uu leeyahay awood dielectric sare ah oo u adkeysan kara saamaynta danab aad u sarreeya.Reactor-ku wuxuu qaataa habka impregnation cadaadiska vacuum, iyo sanqadha la maqli karaa waa yar tahay.
