Dc Reactor Smoothing Reactor

Faʻamatalaga Tekenikali o le DC Reactor (Smoothing Reactor)

Tupu Faʻatasi

Suppression o le Harmonic: Faʻalavelave le AC ripple (20–150Hz) i le tauga DC (typical ≤10% o le ao faʻatagatai).

Mafuaʻaga o le Power Factor: Tautala ai le input PF mai 0.75 ki 0.95 (toʻonui 50Hz).

Faʻavae o le Fesoasoani: E faʻamafuina mai le faʻatino kritikali lea mo le tatau e faʻapito ai le fesoasoani o le rectifier.

Mea Faʻatupu Matua

Inductance: 1–30 mH (faʻavave i mea inverter power rating)

Fesoasoani Rating: 100–3000 A

Voltage Drop: <2% o le tatau voltage

Faʻamatalaga o le Afeafe

Klasa A (Tātasi Maumau):

Grid THDv >5% e tā lea short-circuit capacity >40× rating o le inverter

Sisiemi maumau faʻatatau fiafia (≥3 unite)

Klasa B (Toatoa Maumau):

Transformer faʻatasi e >10× i le toʻonui o le inverter (impedance <4%)

Faʻasaga voleesi: 1.8–3%

Klasa C (Vaai Faʻamafai):

Sistemu mea faʻatupu fesoasoani (tala atoa e talaiga)

Tautau kable puipui (>100 m)

Fa‘avaeaga Fa‘atatalaina

Vaega i le inverter: <5 m (e tatau atamai ai le fa‘aumu o le lalolagi)

Vaega mai le capacitors: ≥3× la‘enga o le mea

Taufua mo le feiloa‘i IGBT (e fa‘amaulalo 2–8 kHz)

Feautupega Ma‘ana

Sensona temperatūra i lalolagi (85°C alarm, 105°C tipi)

Klaso fa'atatau: F (155°C)

Fomula Fa'amamafa:L min =( 2π⋅f⋅ΔIΔU)⋅K(ΔU: faʻamaulalo lea o le fakatatau vola, f: fakatatau faʻasolo, ΔI: faʻamaulalo lea o le fakatatau ampera, K: faʻasaga faʻamanino 1.2–1.5)

Manuia i mea fa'aainumaina:

Fa'amanino lea e fai i le vavega harmonika i le toto ampera e 40–60%

Faʻamālie le faʻatatau moeaga o le kapasita i 15–25%

E fai ma le tusi IEEE 519-2014 mo le faʻatatau o le harmonika.
