Tua o le Afeafe
1. Le faʻatasi paʻa e faʻaigoai manatuina i mea e tali atu (manatuina, vaega mauga)
2. Le mafuaʻaga fai fai o le vaitūtū > 1.8% o le vaitūtū faʻamaulalo
3. Līni lē mafuaʻaga faʻatino maumau (manuia Transformer o le a e lelei i mea 10 feamatai o le uiga o le fequency converter)
4. O le a fiafia e tutusa vā i mea e tofiā i le tala sola mo le faʻatupu i le afuafa o le aoao
5. Tauvaʻo o le capacitors cosφ (faletolu manatu) e sui mai ai le faletolu manatu e faʻatupu ai le afuafa o le aoao
Faʻamatalaga Mea Faʻatupu Faʻamanino
1. Mea Faʻatupu Faʻamanino
Faʻatatau Faletolu
- Faʻaisolation faʻalava: E faʻatupu atu i na harmonika ki luga mai le fesoasoani faʻamataga ma le faʻatupu atu i na harmonika (e.g., 5th, 7th, 11th) e sili ai le fesoasoani i le tala tele.
- E lelei manatuina mo na harmonika faʻamafanafana tele mai le IGBT rectification.
Faʻamanataina Voltage/Current
- Faʻatupu i le overvoltage: E faʻamau atu i na overvoltages faʻamataga (e.g., lightning strikes, switching surges).
- Faʻatasi i le phase: E faʻatasi atu i le mafai o le faʻamataga phase (faʻatoetoe: 1.8%), e faʻaopoopo atu i le mafai o le ena i 3–5%.
- Faʻamatalaga pauga: E faʻaumu i le mafu o le vave e faʻatasi ma le taimi loa e ia ai i mea alofa-vaega (10x le vaega togi a le fakapunipuni pauga).
2. Mea faʻatupu tipikali
- Mea alofa faʻatauina: Le faʻatoʻotoʻoga, faʻavae-vae, ma uo latou e faʻatasi mea alofa (≥400V/50Hz sistemu).
Fuifui tautele:
- Laina e oti i mea kapasita faʻatuai pauga faʻaalamalama (e tusi le resona).
- Sistemu faʻatatau fua (e togi mai i le tatalo magaiga).
- Faʻalavelave e o le a e mafai ona faʻatatau THD (<5%), ifoa o se meaaga vaʻaola/laboratoriki.
3. Mea faʻatupuliamaina Tekenikalia
- Faʻatatau matagi: E agiagi i ni uo o le tausaga i le taimi matafaoaiga (10ms-level).
- Lelei lona faʻamanatuina: Suporta i ni topolojia faʻamanatuina fua (12-pulse, 18-pulse, etc.).
- E paia le fa'atasi ma'a o lea: E silosi le mafaiina moega e 15–20% totonu na'uoi le tali falefakata'e tolu.
pauga Fa'amatalaga Fa'asolo
Mea e molotai:
1. Le amio matagofie moega i le tausitili (e molotai pe a >20kA).
2. Le ao THD matua (e fofopea pe a >8%).
3. Fa'avae o le fa'aogaina (fa'amatalaga i ni mea e fo'i ma le taumuli).
Tēnā le mea e fa'atupu ai le fa'avae fa'atautai ma le fa'asamau manatu i le taimi e fa'amanana, e fa'atasi ai lea i se fa'atatau pa'ia mo lea e fa'apulupulu i se vaitau fakafola ma le vaega fa'amaulalo. I le taimi e tutusa, e feau mai le a e fofo'a ai le fa'avae matagi i lea e fa'atatau i lea o le a e fa'amasinoga i lea o le mea e fa'atatau.
