Chii chandinofanira kuita nekudzivirira kwepamusoro apo kudonhedzwa kunyorera vira yazara simba rekubuda?

1. Chiitiko chekutadza

Iyo inverter inotadza kana iyo yepakati frequency simba ichibuda nesimba rakazara, uye iyo overcurrent chengetedzo yakaitwa. Pane yakaderera simba kubuda, iyo yepakati frequency inodonha kamwe kamwe, Ua inoderera uye Id inowedzera.

2. Kukundikana kuongorora uye kurapwa

Zvinoenderana nechakaipa chiitiko, zvinogara zvichitongwa kuti rimwe bhiriji ruoko rweinverter bhiriji harisi conductive. Kana iyo No. 3 bhiriji ruoko rusina conductive, iyo No. 4 bhiriji ruoko haigone kudzimwa.

Kuona U4 ine oscilloscope zvakare mutsara wakatwasuka. Iyo voltage yeNo. 3 bhiriji ruoko yakaenzana nemhepo inotakura, saka iyo U3 waveform izere sine wave. Kana kukanganisa kwataurwa pamusoro pakaitika, tanga waona kuti thyristor haisi kuitisa here kana chimwe chikamu cheruoko rwebhiriji chakavhurika.

Kana iyo thyristor isiri kuitisa, iyo oscilloscope inogona kushandiswa kuenderera mberi kuona kana iyo trigger yedunhu yakanganisa, iyo thyristor control pole inotadza, kana mutsara wakashata.

Chekutanga shandisa oscilloscope kutarisa kana pane chinokonzeresa kupomba paruoko rwebhiriji uye kana kupuruzira kupuruzira kwakajairika. Kana iyo trigger pulse isiri yakajairika, kukanganisa kuri mumutsara wedunhu. Shanduko inofanira kuiswa panzvimbo yekuongorora, uye mafungu ega ega ega ega edunhu rinokonzeresa anofanira kutariswa nhanho nhanho kuti awane kukanganisa. point. Kana iyo trigger pulse iri yakajairika, shandisa multimeter kuti uone kana danda rekutonga re thyristor rakazaruka kana pfupi.

Kana zvakajairika, tarisa kushorwa pakati peiyo control electrode uye cathode ye thyristor. Kana kupikisa kwemukati kwedanda rekutonga kwakanyanya, shandura thyristor.

Kana iyo thyristor ichigara yakadzimwa, tarisa kana boka rema thyristors riri kure rakapfupika. Kana zvakajairika, tarisa kana nguva yekudzima ye thyristor yakarebesa.
