Nzira yekusarudza yemhando yepamusoro induction yakanyungudika choto?

1. Iyo rectifier circuit ye ​​induction melting furnace ndeye bhiriji rectifier, iyo yakakamurwa kuita zvikamu zvitatu uye zvitanhatu zvikamu. Pakati pavo, matatu-phase bridge rectifier circuit inoumbwa nemapoka matatu e thyristors, anowanzozivikanwa se matanhatu-pulse rectification; nhanhatu-chikamu bhiriji rectifier circuit inoumbwa nemapoka matanhatu e thyristors, anowanzozivikanwa segumi nemaviri-pulse rectification; inoshandiswawo mune yakakwirira-simba induction kunyungudutsa mavira. Kune makumi maviri nemana pulse rectification kana makumi mana nesere pulse rectification.

Nheyo yekushanda yerectifier circuit ye kudonhedzwa kunyorera vira ndiko kuronga thyristor inoenderana kuti ibatidzwe uye ichidzimwa panguva yakakodzera maererano neimwe mutemo, uye pakupedzisira kuona kutendeuka kwetatu-chikamu chinochinjisa ikozvino mune yakananga ikozvino.

2. The inverter circuit ye ​​induction melting furnace ndeye kushandura yakagadziriswa yakananga ikozvino kune yakakwirira frequency alternating current kuti ipe coil load, saka iyi induction inonyungudutsa furnace inverter ndeye “AC-DC-AC” maitiro.

Iyo inverter dunhu reiyo induction yakanyunguduka choto yakakamurwa kuita parallel resonance inverter furnace uye akateedzana resonance inverter wedunhu. Iyo parallel resonant inverter yedunhu inoshandiswa zvakanyanya, uye ingangoita ese ekutanga induction kunyungudutsa mavira anoshandisa iyi control circuit, iyo ine kukura. Izvo zvisingabatsiri ndezvokuti simba rinowedzera nekuwedzera kwechaji, uye simba guru rinenge rinenge 0.9; the series inverter induction melting furnace yakaonekwa mumakore gumi apfuura, uye chakanakira ndechekuti iyo simba chinhu chakakwira, kazhinji pamusoro pe0.95, inogona kuona miviri miviri yevira inoshanda panguva imwe chete, saka inodaidzwa kuti imwe-ye-maviri kunyunguduka. choto muindasitiri yekuwana.

3. Yekusefa kwe kudonhedzwa kunyorera vira, nekuda kwekushanduka kukuru kwemagetsi akagadziridzwa, zvakakosha kubatanidza inductor huru munhevedzano munharaunda kuitira kuti ikozvino iite zvakanaka, iyo inogona kuita kuti magetsi ane kushanduka kukuru kuve nyore. Izvi zvinonzi kusefa. Iyi inductance inowanzonzi reactor. Chimiro che reactor ndechekuchengetedza ikozvino kubva pakushanduka kamwe kamwe.

Iyo induction yakanyunguduka choto inopihwa kune inverter wedunhu kuburikidza neyakatsetseka DC simba mushure mekusefa. Series midziyo inosefa nema capacitors kuti iwane voltage yakapfava.
