Chii chinonzi Harmonics?

Vatengi vanowedzera vane hanya nezve harmonics, saka chii chinonzi harmonic, chii chiri kukuvadza kweharmonic, ikozvino regai ndikupe imwe sumo.

Mune izwi, mumagetsi emagetsi system, harmonic yeazvino kana voltage waveform is sinusoidal wave iyo frequency ndeye nhamba yakawanda yeiyo yakakosha frequency.

MuUSA, iyi yakakosha frequency ndeye 60Hz, asi mumisika yeEurope neAsia, inogona kunge iri 50Hz.Muhurongwa hwe60Hz hunogona kusanganisira 2nd-order harmonics pa120Hz, 3rd-order pa180Hz, 5th-order pa300Hz, etc. Mu50Hz system inogona kusanganisira 2nd-order harmonics pa100Hz, 3rd-order pa150Hz, 5th-order 250Hz, zvichingodaro. Zvakasanganiswa, zvinounza kukanganisa kwese kune yakakosha frequency waveform.

Iwe une mubvunzo mukuru pamusoro pekuti harmonics inogadzirwa sei?

Mitoro isina mutsetse inoburitsa maharonic frequency nekuchinja nekukurumidza, senge madhiraivha madhiraivha, anochinja-chinja madhiraivha, rectifiers, servo madhiraivha, mwenje we LED, kana michina yemagetsi yakazadza semidziyo yemagetsi.Mukuita kwekugadzirisa uye inverting, nekuda kweiyo yakakwira switching frequency, yakakwira harmonics ichagadzirwa.

Harmonics chero kukuvadza kune magetsi emagetsi system?Hongu, zvinofanira.

Sezvo akawanda uye akawanda emagetsi emagetsi emagetsi majenareta akasanganiswa mune yedu yekugovera magetsi network, magetsi emagetsi masisitimu achaona zvakanyanya kukuvadza harmonics.

Harmonics inofanira kuva nemigumisiro yakakomba zvikuru.Kana ma harmonics akakuvadza mudziyo unonzwisisika, zvinogona kukonzera kutadza kwekugadzira.Iyo harmonics inogona kukonzera kuti magetsi ese adzike.Nekuda kwesimba rinoshanda, kusaenzana kwechikamu, kushanduka kwemagetsi (flicker), uye yakakwira harmonic zvazvino zvinokanganisa, gidhi remagetsi rinofanirwa kusangana nekukanganisika kana kuremerwa zvine njodzi.

Kana paine nzira yatingagona kugadzirisa iyo harmonics?Ehe, Noker Electric ichakubatsira kuita izvi.

Xi'an Noker Electric inyanzvi yesimba remhando yechigadzirwa inogadzira, inopainoshanda simba sefa, reactive simba compensator, hybrid compensatornezvimwe zvigadziriso.Kana uine dambudziko remhando yemagetsi, ndapota inzwa wakasununguka kutibata nesu.
