Shaandheynta Wajiga Saddexaad ee Korantada Hoose ee Shaandheynta Wadaagga ah ee Vfd 400v Sawirka

Shaandheynta Wajiga Saddexaad ee Korantada Hoose ee Dadban ee Harmonic ee loogu talagalay Vfd 400v

Sharaxaad Gaaban:

Filterka harmonic dadban wuxuu adeegsadaa mabda'a soo-saarka korantada iyo reactor, wuxuu doortaa capacitor filtarka leh waxqabadka sare iyo aaladda shaandheynta oo leh khad sare, wuxuuna isku daraa nidaamka magdhowga filtarrada si uu u nuugo qaybaha iswaafajinta ee nidaamka isla markaana magdhabida awoodda falcelinta ee isku mar.

Shaqada magdhowga tamarta firfircoon ee firfircoon iyo shaandhaynta ayaa lagu dhex milmay mid, kaas oo si dhakhso ah ula socon kara isbeddelka rarka, oo leh saddex hawlood oo waaweyn: xakamaynta isbedbeddelka hadda, nuugista iswaafajinta iyo magdhowga awoodda falcelinta.Waxaa loo istcimaalaa in lagu dhimo mowjadaha aan-sine-ka ahayn ee ay dhaliyaan rogayaasha, servo drives, UPS, iwm, ee xadhkaha korantada warshadaha.

Astaamaha

Filterka harmonic dadban si weyn loogu isticmaalo saddex weji ee nidaamka silig.Waxay isticmaashaa mabda'a soo-saarka elektromagnetic-ka iyo reactor, waxay doorataa capacitor filtarka leh waxqabadka sare iyo aaladda shaandhada leh linearity sare, waxayna isku daraysaa nidaamka magdhowga filter si uu u nuugo qaybaha iswaafajinta ee nidaamka isla markaana magdhabida awooda falcelinta isla waqti isku mid ah.Shaqada magdhowga tamarta firfircoon ee firfircoon iyo shaandhaynta ayaa lagu dhex milmay mid, kaas oo si dhakhso ah ula socon kara isbeddelka rarka, oo leh saddex hawlood oo waaweyn: xakamaynta isbedbeddelka hadda, nuugista iswaafajinta iyo magdhowga awoodda falcelinta.Waxaa loo istcimaalaa in lagu dhimo mowjadaha aan-sine-ka ahayn ee ay dhaliyaan rogayaasha, servo drives, UPS, iwm, ee xadhkaha korantada warshadaha.

1. Heerka korantada: saddex-waji oo saddex-xarig ah oo lagu qiimeeyay danab 380-500V, leexsanaanta la oggol yahay ± 10%

2. Xakamaynta iswaafajinta: THDi<10%, nambarka wada siman 2n-1=1 ~ 40

3. Soo noqnoqda: 50± 5 (Hz);Qodobka awoodda: dhexroorka COS>0.9

4. Saamaynta shaandhaynta: waafaqsan IEC61000, GB/T14549-93

5. Heerkulka shaqada: -10 ~ +50 (℃);Heerkulka kaydinta: -40 ~ +65 (℃);Qoyaanka jawiga: 0 ~ 98(%) malaha uumi;Joog: <2000M

6. Qaab dhismeedka: Qaab dhismeedka caadiga ah, rakibida dabaqa, ama habaynta macaamiisha (ikhtiyaar)

7. Awoodda xad-dhaafka ah: culeyska 120% ee qiimaha la qiimeeyay wuxuu si caadi ah u shaqeeyaa 30 daqiiqo

8. Habka rakibaadda: rakibid gaar ah, rakibid taageeraya, ama habeynta macaamiisha (ikhtiyaar), dhig meel bannaan oo kuleyl ah oo 100mm ah oo ku wareegsan shaandhada harmonic

9. Loo isticmaalo shaandhaynta faragelinta xooggan ee warshadaha, gaar ahaan ku habboon beddelka.

Isticmaalka

1. Maamulka filtarrada is-waafajinta ballaaran ee shaandhaynta guddoomiyaha beddelka soo noqnoqda (VSD) iyo wareegyada kale ee saddex-waji ah ee hagaajinta ee ay dhaliso is-waafajinta muhiimka ah;

2. Yaree luminta iswaafajinta nidaamka duritaanka, sidaas darteed badbaadinta awoodda, waxtarka>99%;

3. Hubi in heerka qallooca hadda iyo korantada ee dhamaadka galitaanka shaandhada harmonic uu buuxiyo shuruudaha heerka 1EEE 51.9;

4. Wadarta heerka leexinta baahida hadda jirta (TDD) ee dhamaadka gelinta shaandhada iswaafajinta kama badanayso xadka lagu sheegay shaxda 10.3 ee heerka 1EEE 51 9;

5. Sababtoo ah awoodda falceliska kaabtiyeeed ee aadka u hooseeya, waxa si fiican loogu isticmaali karaa matoorada naaftada xitaa marka la dejiyo;

6. Awood yar oo firfircooni ah sidoo kale uma baahna in la isticmaalo xiriiriyaha beddelka capacitive (sidoo kale waxaa lagu dari karaa marka loo baahdo);

7. Dhexdhexaadinta culeyska caadiga ah, qodobka korantadu wuxuu ahaanayaa inta u dhaxaysa 0.95 iyo 0.98 (40 ilaa 100% load);

8. Uma ekaan doono qaybaha kale ee nidaamka awoodda, ma nuugi doono harmonics dhinaca khadka;

9. Waxa uu hor istaagi karaa farqiga hirarka korantada ee korantada, furitaanka iyo xidhida bangiyada capacitor-ka ama culayska kale ee si degdega ah isu beddelaya;

10. Hagaajinta qodobka awoodda ee nidaamka oo dhan ka dib markii la baabi'iyo harmonics;

11. Xaaladda kaliya ee culeyska beddelka soo noqnoqda ee guddoomiyaha, ku habboon sahayda korantada guddoomiyaha beddelka soo noqnoqda ee isku mar;
