Triple Phase Yakaderera Voltage Passive Harmonic Sefa yeVfd 400v
Iyo passive harmonic sefa inoshandiswa zvakanyanya muchikamu chetatu waya system.Inoshandisa musimboti we electromagnetic induction uye reactor, inosarudza iyo sefa capacitor ine yakanyanya kuita uye sefa mudziyo ine yakakwira mutsara, uye inosanganisa iyo sefa yekubhadhara system kuti itore iyo huru harmonic zvikamu muhurongwa uye kudzoreredza iyo inoshanda simba panguva imwe chete.Basa rekugadzirisa reactive simba rekubhadhara uye kusefa rinosanganiswa mune imwe, iyo inogona kukurumidza kutevera kuchinja kwemutoro, uye ine mabasa matatu makuru: kudzvinyirira ikozvino kuchinja, kutora harmonic uye kubhadhara simba rinoshanda.Inoshandiswa kudzikisa isiri-sine wave ikozvino inogadzirwa nemainverters, servo madhiraivha, UPS, nezvimwewo, mumaindasitiri emagetsi magidhi.
1. Voltage level: matatu-chikamu matatu-waya yakatarwa voltage 380-500V, inobvumirwa kutsauka ± 10%
2. Harmonic control: THDi<10%, harmonic nhamba 2n-1=1 ~ 40
3. Frequency: 50±5(Hz);Simba chinhu: COS dhayamita> 0.9
4. Kusefa maitiro: zvinoenderana neIEC61000, GB/T14549-93
5. Kushanda tembiricha: -10 ~ +50 (℃);Kuchengetedza tembiricha: -40 ~ +65 (℃);Ambient humidity: 0 ~ 98(%) hapana condensation;Kureba: <2000M
6. Chimiro: Chimiro chakajairwa, kuisirwa pasi, kana kugadzirisa mutengi (sarudzo)
7. Kuwedzera simba: kuwedzeredza 120% yehuwandu hwehuwandu hunoshanda kazhinji kwemaminitsi makumi matatu
8. Kuisa nzira: kupatsanura kuisirwa, kutsigira kuisirwa, kana kugadzirisa mutengi (kusarudza), isa parutivi 100mm kupisa kwekupisa nzvimbo yakatenderedza harmonic sefa.
9. Inoshandiswa kune indasitiri yakasimba kupindira kusefa, kunyanya yakakodzera inverter.
1. The wide spectrum harmonic filter governance by frequency conversion governor (VSD) uye mamwe matatu-phase rectifier circuit inogadzirwa neharmonics huru;
2. Deredza kurasikirwa kweharmonic yejekiseni system, nokudaro kuchengetedza simba, kushanda zvakanaka> 99%;
3. Iva nechokwadi chokuti ikozvino uye kukanganiswa kwemagetsi pamagumo ekupinza kweharmonic filter inosangana nezvinodiwa zve 1EEE 51.9 standard;
4. Iyo yakazara ikozvino inoda kukanganisa chiyero (TDD) pamugumo wekupinza weharmonic sefa haipfuuri muganhu unotsanangurwa muTebhu 10.3 ye1EEE 51 9 muyero;
5. Nekuda kweiyo yakaderera capacitive reactive simba, inogona kushandiswa zvakanaka nemajenereta edhiziri kunyange kana yaburitswa;
6. Low capacitance reactive simba zvakare haidi kushandisa capacitive switching contactor (inogonawo kuwedzerwa kana zvichidiwa);
7. Mukati memutoro wenguva dzose, simba rinoramba riri pakati pe0.95 ne0.98 (40 kusvika 100% mutoro);
8. Hazvizopindirana nezvimwe zvikamu zvesimba remagetsi, hazvizotora harmonics padivi remutsara;
9. Inogona kurambidza commutation voltage waveform gap, kuvhura nekuvhara capacitor mabhangi kana imwe inokurumidza kuchinja mutoro unogadzirwa overvoltage;
10. Kuvandudza simba rekugadzirisa kwese mushure mekubvisa harmonics;
11. Panyaya yenguva chete yekutendeuka gavhuna mutoro, yakakodzera kune akawanda frequency kutendeuka gavhuna magetsi panguva imwe chete;
12. Deredzai frequency conversion governor (VSD) inogadzirwa nekukanganiswa kweredhiyo conduction;
13. Line reactor mafirita ezvakasiyana siyana anowanikwa kune AC drive, DC drive kana zvimwe zvinodzoreka zvinodzoreredza midziyo.
Iyo passive harmonic sefa inogona kushandiswa zvakanyanya senge pazasi:
Dc inokurumidza kuchaja mudziyo
Heating ventilation uye air conditioning unit
Exhaust mhepo uye pombi system
Industrial otomatiki uye marobhoti midziyo
Ac uye DC mota inotyaira, inverters
Mudziyo une chemberi six-pulse rectifier
1. ODM/OEM sevhisi inopiwa.
2. Kurumidza kurongeka kusimbiswa.
3. Kurumidza kutumira nguva.
4. Yakanaka nguva yekubhadhara.
Parizvino, kambani iri kuwedzera nesimba misika yemhiri kwemakungwa uye marongero epasi rose.Takazvipira kuve rimwe remabhizinesi gumi epamusoro ekutengesa kunze kwenyika muChina chigadzirwa chemagetsi otomatiki, kushandira nyika nezvigadzirwa zvemhando yepamusoro uye kuwana mukana wekuhwina nevatengi vakawanda.
