Mhedzisiro huru yeharmonics

Harmonics inoonekwa zvakanyanya uye kazhinji muhupenyu hwedu hwezuva nezuva.The kakawanda kuwana yakakwirira kuvapo harmonics kazhinji muzvipatara, mumayunivhesiti, hurumende nzvimbo, zvitoro, marabhoritari, anorema maindasitiri, redhiyo, TV, kutepfenyura, zvokudya indasitiri, hotera uye casino, zvikuru otomatiki indasitiri, mvura kurapwa plant.The zvikuru common harmonic generating midziyo inosanganisira: switching power rectifiers, welders,Ups, old frequency converter ne thyristor power converter tekinoroji, madhiraivha emota, maconverter ane controlled rectifiers, DC controller yeDC madhiraivha, Induction oveni.
Mhedzisiro mikuru yeharmonics senge pazasi:
1.Kupisa zvakanyanya uye kudengenyeka nekukwegura kusati kwasvika kwezvikamu zvose, nemigumisiro yenguva pfupi uye yepakati pane tarisiro yehupenyu.
2.Kukanganisa pamagetsi emagetsi emagetsi.
3.Kukuvadza kune zvakadhindwa zvikamu zvebhodhi redunhu.
4.Electric motor overload.
5.Premature aging capacitors uye kukuvara nekuda kweresonance.
6.Power factor kuderedza.
7.Kuwedzeredza kwetambo isina kwayakarerekera.
8.Electromagnetic pesvedzero.
9.Measurement kukanganisa pamamita emagetsi.
10.MCCB uye contactor kukanganisa kukanganisa.
11.Kutadza kutenderera kwekuchinja.
Active harmonic filtersndiwo midziyo yemhando yesimba iyo inopa zvine simba inodzorwa ikozvino ine amplitude yakafanana neye harmonic ikozvino, iyo inobaiwa inopesana neharmonics pane network.Izvi zvichabvisa harmonic ikozvino mumagetsi emagetsi.Nekuda kweizvozvo, iyo yazvino inopihwa neiyo sosi yemagetsi icharamba iine sinusoidal sezvo maharmonics achadzima mumwe nemumwe kunze uye kukanganiswa kweharmonic kunoderedzwa kusvika kune yakaderera kukosha.
Masefa anoshandainogona kuiswa chero pane network uye inopa akawanda maficha:
1.Kubvisa yose harmonic currents kusvika ku50th order kubva kune zvisiri-mutsara mitoro.
2.Compensate reactive simba uye kugadzirisa simba chinhu.
3.Compensate for flicker inokonzerwa ne reactive simba.
Noker Electricinoshanda simba sefainotora tekinoroji yepamusoro-yepamusoro-nhatu, ine hunhu hudiki, huwandu hwesimba, hwakagadzikana uye hwakavimbika kuita, hunofarirwa nevatengi. Inogona kungoita harmonic hutongi, reactive simba muripo, zvakare inogona kuita harmonic hutongi + reactive simba. muripo, harmonic frequency kubva pa3 kusvika pa50 harmonic, inogona kuwedzera optimization yegridi yako mhando.
