Kugwiritsa ntchito fyuluta yogwira ntchito ya harmonic ndi chiyani

Pogwiritsa ntchito kwambiri liwiro loyendetsa, servo, ups ndi zinthu zina, ma harmonics ambiri awonekera mu gridi yamagetsi, ndipo ma harmonics abweretsa mavuto aakulu kwambiri.Pofuna kuthetsa vuto la harmonic mu gridi yamagetsi, kampani yathu yapanga magawo atatufyuluta yogwirakutengera sefa yogwira ya magawo awiri.

Chosefera chogwira ntchitoangagwiritsidwe ntchito kwambiri m'mafakitale, malonda ndi mabungwe kugawa maukonde, monga: machitidwe magetsi, electrolytic plating mabizinesi, zipangizo madzi mankhwala, mabizinesi petrochemical, masitolo akuluakulu ndi nyumba maofesi, mwatsatanetsatane mabizinesi zamagetsi, ndege/doko magetsi magetsi, mabungwe azachipatala , etc. Malinga ndi zinthu zosiyanasiyana ntchito, ntchito yafyuluta yamphamvu yogwiraidzatenga gawo pakuwonetsetsa kudalirika kwamagetsi, kuchepetsa kusokoneza, kukonza zinthu zabwino, kuwonjezera moyo wa zida ndi kuchepetsa kuwonongeka kwa zida.

The 3rd harmonic m'mafakitale ambiri a semiconductor ndizovuta kwambiri, makamaka chifukwa cha kuchuluka kwa zida zowongolera gawo limodzi zomwe zimagwiritsidwa ntchito m'mabizinesi.Harmonic yachitatu ndi ya zero sequence harmonics, yomwe ili ndi mawonekedwe osonkhanitsidwa mumzere wosalowerera ndale, zomwe zimapangitsa kuti pakhale kukakamizidwa kwambiri pamzere wosalowerera ndale, komanso chodabwitsa choyaka moto, chomwe chimakhala ndi zoopsa zobisika pachitetezo chopanga.Ma Harmonics amathanso kupangitsa kuti ophwanya madera aziyenda, kuchedwetsa nthawi yopanga.Haronic yachitatu imapanga kufalikira mu thiransifoma ndikufulumizitsa ukalamba wa thiransifoma.Kuipitsa kwakukulu kwa harmonic kudzakhudza momwe ntchitoyo ikuyendera komanso moyo wa zida mu dongosolo logawa mphamvu.

Maulalo ambiri owongolera ma inverter ndikugwiritsa ntchito ma pulses 6 kuti asinthe AC kukhala DC, kotero ma harmonics omwe amapangidwa amakhala makamaka 5, 7, 11.Zowopsa zake zazikulu ndizowopsa kwa zida zamagetsi ndi kupatuka kwa kuyeza.Kugwiritsa ntchitofyuluta yogwiraikhoza kukhala njira yabwino yothetsera vutoli.

Kugwiritsa ntchitoyogwira harmonicfyuluta:

1. Zosefera panopa harmonics, amene angathe efficiently zosefera kunja harmonics 2-25 nthawi katundu panopa, kuti kugawa maukonde woyera ndi kothandiza, ndi kukwaniritsa zofunikira za muyezo dziko kwa kugawa maukonde kudula.Zosefera zogwira ntchito zowongolera zolondola, zimatha kuzindikira zosintha zonse ndikuyika zosintha zamtundu uliwonse ndikutsata chipukuta misozi, kuyankha kwa 80us posintha kusintha, 20ms kuti mupeze chipukuta misozi chonse.

2. Kupititsa patsogolo kusalinganika kwa dongosolo, kungathe kuthetsa kusamvana kwadongosolo komwe kumayambitsidwa ndi ma harmonics, pankhani ya zilolezo za mphamvu za zida, zikhoza kukhazikitsidwa malinga ndi wosuta kuti apereke malipiro a dongosolo lokhazikika lokhalokha ndi ziro zomwe zimayenderana bwino komanso mphamvu zolimbitsa thupi zolipirira.

3. Imalepheretsa kugwedezeka kwa gridi yamagetsi, yomwe siidzagwirizana ndi gridi yamagetsi, ndipo imatha kutsanzira mogwira mtima kumveka kwa gridi yamagetsi yokha mkati mwa mphamvu yake.

4. Ntchito zosiyanasiyana zodzitetezera, zokhala ndi magetsi opitilira apo, voteji, pansi pa voteji, kutentha kwambiri, vuto la dera loyezera, kugunda kwamphezi ndi ntchito zina zoteteza.

5. Kugwiritsa ntchito digito kwathunthu, ndi mawonekedwe ochezeka a makina a munthu, kupangitsa kuti ntchitoyi ikhale yosavuta, yosavuta kugwiritsa ntchito komanso yosamalira.
