Isihluzo se-Passive Harmonic seVfd iSigaba seSithathu se-400v Umfanekiso obonakalayo

Isihluzi sePassive Harmonic seVfd isiGaba esiThathu se-400v

Inkcazelo emfutshane:

Isihluzi esisebenzayo se-harmonic sisebenzisa umgaqo wokungeniswa kwe-electromagnetic kunye ne-reactor, ikhetha i-capacitor yokucoca ngokusebenza okuphezulu kunye nesixhobo sokucoca esinomgca ophezulu, kwaye sidibanisa inkqubo yembuyekezo yokucoca ukufunxa awona macandelo e-harmonic kwinkqubo kwaye ubuyekeze amandla asebenzayo kwisixhobo. xeshanye.

Umsebenzi wembuyekezo yamandla asebenzayo asebenzayo kunye nokucoca idityaniswe kwelinye, elinokuthi lilandele ngokukhawuleza utshintsho lomthwalo, kwaye linemisebenzi emithathu ephambili: ukucinezela ukuguquguquka kwangoku, ukufunxa i-harmonic kunye nokuhlawula amandla asebenzayo.Isetyenziselwa ukunciphisa i-non-sine wave yangoku eyenziwa ngabaguquli, ii-servo drives, i-UPS, njl., kwiigridi zamandla oshishino.

Isihluzo se-harmonic esisebenzayo sisetyenziswa ngokubanzi kwisigaba sesithathu senkqubo yocingo.Isebenzisa umgaqo wokungeniswa kwe-electromagnetic kunye ne-reactor, ikhetha i-capacitor yokucoca ngokusebenza okuphezulu kunye nesixhobo sokucoca esinomgca ophezulu, kwaye idibanisa inkqubo yembuyekezo yokucoca ukufunxa izinto eziphambili ze-harmonic kwisistim kwaye ibuyekeze amandla asebenzayo ngaxeshanye.Umsebenzi wembuyekezo yamandla asebenzayo asebenzayo kunye nokucoca idityaniswe kwelinye, elinokuthi lilandele ngokukhawuleza utshintsho lomthwalo, kwaye linemisebenzi emithathu ephambili: ukucinezela ukuguquguquka kwangoku, ukufunxa i-harmonic kunye nokuhlawula amandla asebenzayo.Isetyenziselwa ukunciphisa i-non-sine wave yangoku eyenziwa ngabaguquli, ii-servo drives, i-UPS, njl., kwiigridi zamandla oshishino.

1. Inqanaba lombane: isigaba sesithathu sombane olinganiswe ngocingo 380-500V, ukutenxa okuvumelekileyo ± 10%

2. Ulawulo lwe-Harmonic: I-THDi<10%, inombolo ye-harmonic 2n-1=1 ~ 40

3. Ukuphindaphinda: 50±5(Hz);Umba wamandla: I-COS idayamitha>0.9

4. Isiphumo sokuhluza: ngokuhambelana ne-IEC61000, GB/T14549-93

5. Ubushushu bokusebenza: -10 ~ +50 (℃);Ubushushu bokugcina: -40 ~ +65 (℃);Ukufuma kwendawo: 0 ~ 98(%) akukho ukujiya;Ukuphakama: <2000M

6. Ulwakhiwo: Ulwakhiwo olusemgangathweni, ufakelo lomgangatho, okanye ukulungelelanisa umthengi (ukhetho)

7. Umthamo wokugcwala: ukulayisha ngaphezulu kwe-120% yexabiso elilinganisiweyo lisebenza ngokuqhelekileyo kwimizuzu engama-30

8. Indlela yokufakela: ufakelo olwahlukileyo, ufakelo oluxhasayo, okanye ulungelelwaniso lomthengi (ukhetho), bekela bucala indawo yokuchitha ubushushu eyi-100mm ejikeleze isihluzo seharmonic.

9. Isetyenziselwa ukuhluza okuqinileyo kokuphazamiseka kwimizi-mveliso, ilungele ngakumbi i-inverter.

Ukusetyenziswa

1. I-wide spectrum ye-harmonic filter governance by frequency conversion governor (VSD) kunye nezinye izigaba ezithathu zokulungisa isekethe eveliswa zii-harmonics eziphambili;

2. Ukunciphisa ilahleko ye-harmonic yenkqubo yokutofa, ngaloo ndlela igcina amandla, ukusebenza kakuhle> 99%;
