Isihlungi Se-Passive Harmonic Sesithombe Esifakiwe se-Vfd Isigaba Sesithathu esingu-400v

Isihlungi se-Passive Harmonic Se-Vfd Isigaba Sesithathu 400v

Incazelo emfushane:

Isihlungi se-harmonic esingenzi lutho sisebenzisa isimiso sokungeniswa kwe-electromagnetic kanye ne-reactor, sikhetha i-capacitor yesihlungi esebenza kahle kanye nedivayisi yokuhlunga enomugqa ophezulu, futhi sihlanganisa uhlelo lwesinxephezelo sokuhlunga ukuze lumunce izingxenye eziyinhloko ze-harmonic ohlelweni futhi lunxephezele amandla asebenzayo Ngisikhathi esifanayo.

Umsebenzi wesinxephezelo samandla asebenzayo ashukumisayo nokuhlunga kuhlanganiswe kokukodwa, okungalandela ngokushesha ushintsho lomthwalo, futhi kunemisebenzi emithathu eyinhloko: ukucindezela ukushintshashintsha kwamanje, ukumunca i-harmonic kanye nokunxephezela amandla asebenzayo.Isetshenziselwa ukunciphisa i-non-sine wave yamanje ekhiqizwa ama-inverters, ama-servo drives, i-UPS, njll., kumagridi wamandla wezimboni.

Izici

Isihlungi se-harmonic ye-passive esetshenziswa kabanzi ohlelweni lwezintambo zesigaba sesithathu.Isebenzisa isimiso sokungeniswa kwe-electromagnetic kanye ne-reactor, ikhetha i-capacitor yesihlungi esebenza kahle kanye nedivayisi yokuhlunga enomugqa ophezulu, futhi ihlanganisa uhlelo lwesinxephezelo sokuhlunga ukuze lumunce izingxenye eziyinhloko ze-harmonic ohlelweni futhi lunxephezele amandla asebenzayo ngesikhathi esifanayo.Umsebenzi wesinxephezelo samandla asebenzayo ashukumisayo nokuhlunga kuhlanganiswe kokukodwa, okungalandela ngokushesha ushintsho lomthwalo, futhi kunemisebenzi emithathu eyinhloko: ukucindezela ukushintshashintsha kwamanje, ukumunca i-harmonic kanye nokunxephezela amandla asebenzayo.Isetshenziselwa ukunciphisa i-non-sine wave yamanje ekhiqizwa ama-inverters, ama-servo drives, i-UPS, njll., kumagridi wamandla wezimboni.

1. Izinga lamandla kagesi: i-voltage elinganiselwe yezigaba ezintathu enezintambo ezintathu 380-500V, ukuchezuka okuvumelekile ±10%

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

3. Imvamisa: 50±5(Hz);Isici samandla: Ububanzi be-COS >0.9

4. Umphumela wokuhlunga: ngokuhambisana ne-IEC61000, GB/T14549-93

5. Izinga lokushisa lokusebenza: -10 ~ +50 (℃);Ukushisa kwesitoreji: -40 ~ +65 (℃);Umswakamo we-ambient: 0 ~ 98(%) akukho ukujiya;Ukuphakama: <2000M

6. Isakhiwo: Isakhiwo esijwayelekile, ukufakwa phansi, noma ukwenza ngokwezifiso ikhasimende (uyazikhethela)

7. Umthamo wokulayisha ngokweqile: ukulayisha ngokweqile okungu-120% yenani elilinganiselwe lisebenza ngokujwayelekile imizuzu engama-30

8. Indlela yokufaka: ukufakwa okuhlukene, ukufaka okusekelayo, noma ukwenza ngokwezifiso ikhasimende (uyazikhethela), bekela eceleni isikhala esingu-100mm sokulahla ukushisa esizungeze isihlungi se-harmonic.

9. Isetshenziselwa ukuhlunga okuqinile kokuphazamiseka kwezimboni, kulungele ikakhulukazi inverter.

Ukusetshenziswa

1. Ukulawulwa kwesihlungi se-spectrum esibanzi se-harmonic nge-frequency conversion governor (VSD) kanye nesekhethi yokulungisa izigaba ezintathu ekhiqizwe ama-harmonic amakhulu;

2. Yehlisa ukulahleka kwe-harmonic yesistimu yomjovo, ngaleyo ndlela wonge amandla, ukusebenza kahle> 99%;

3. Qinisekisa ukuthi izinga lamanje nelokuhlanekezelwa kwamandla kagesi ekugcineni kokufaka kwesihlungi se-harmonic lihlangabezana nezimfuneko zezinga le-1EEE 51.9;

4. Isamba sesilinganiso samanje sokuhlanekezela kwesidingo (TDD) ekugcineni kokufaka kwesihlungi se-harmonic aweqi umkhawulo oshiwo kuThebula 10.3 lezinga le-1EEE 51 9;

5. Ngenxa yamandla aphansi we-capacitive reactive, angasetshenziswa kahle namajeneretha edizili ngisho nalapho elayishiwe;

6. Amandla asebenzayo aphansi we-capacitance nawo awadingi ukusebenzisa i-capacitive switching contactor (ingaphinde yengezwe lapho kudingeka);

7. Ngaphakathi kwebanga elijwayelekile lomthwalo, isici samandla sihlala siphakathi kuka-0.95 no-0.98 (umthwalo ongu-40 kuya ku-100%);

8. Ngeke ihambisane nezinye izingxenye zesistimu yamandla, ngeke imunce ama-harmonics ohlangothini lomugqa;

9. Ingakwazi ukuvimbela igebe le-voltage ye-waveform eshintshayo, ivule futhi ivale amabhange e-capacitor noma omunye umthwalo oshintsha ngokushesha okhiqizwa u-overvoltage;

10. Thuthukisa isici samandla salo lonke uhlelo ngemva kokuqeda ama-harmonics;

11. Endabeni yomthwalo we-frequency conversion governor kuphela, ofanele ukunikezwa kwamandla kambusi wokuguqulwa kwamafrikhwensi amaningi ngesikhathi esisodwa;

12. Nciphisa i-frequency conversion governor (VSD) edalwa ukuphazamiseka kokuqhutshwa komsakazo;

13. Izihlungi ze-reactor zomugqa zokucaciswa okuhlukahlukene ziyatholakala kudrayivu ye-AC, idrayivu ye-DC noma amanye amadivaysi okulungisa izinto alawulekayo.
