Inverter intermediate frequency furnaces must have advantages over parallel intermediate frequency furnaces

1. The thyristor parallel circuit is parallel resonance intermediate frequency furnace. Munguva yekunyunguduka, kunyanya kunyunguduka kwealuminium, mhangura uye zvimwe zvinhu, mutoro wacho wakareruka, uye simba rayo rinobuda iduku kwazvo, rine zvakawanda zvine chokuita nemhando yemutoro, saka kunyunguduka kwayo kunononoka , Kuoma. mukupisa. Iyo thyristor yakatevedzana yepakati frequency yekunyungudutsa choto inogadzirisa simba kuburikidza ne frequency modulation, saka haina kukanganiswa nehunhu hwemutoro. Kunyungudika kwese kunenge kunochengetedza simba rinogara richibuda. Nekuti iri nhevedzano resonance, kureva, voltage resonance, iyo induction coil voltage yakakwira uye yazvino idiki, saka Iko kurasikirwa kwesimba kudiki.

2. Nemhaka yokuti inverter yakatevedzana, simba remagetsi rakakwirira uye harmonics idiki, saka hapana chikonzero chekuisa reactive simba rekubhadhara mudziyo. Izvi zvinogona kuchengetedza vashandisi mari yakawanda, uye zvakare chishandiso chepamberi icho dhipatimendi rekupa magetsi rinosimudzira nesimba.

3. Kana iyo yakatevedzana yepakati frequency furnace iri kushanda, iyo rectifier inogara ichishanda mu-yakazara-panyika, uye inobuda simba reinverter redunhu rinoshandurwa nekudzora inverter trigger pulse frequency. Uye iyo yazvino mutoro ndeye sine wave, saka iyo yakatevedzana yepakati frequency choto haizoshatise zvakanyanya gidhi remagetsi neakakwira harmonics, uye iyo simba chinhu chakakwira. Parallel inverters haigone kuwana imwe-kusvika-mbiri otomatiki magetsi ekugadzirisa mashandiro, nekuti gadziriso yemagetsi yeparallel inverter magetsi inogona kuwanikwa chete nekugadzirisa yakabuda voltage yebhiriji rectifier. Kana iyo parallel inverter rectifier bhiriji ichishanda pane yakaderera voltage, iyo yekugadziridza conduction angle idiki kwazvo. Munyika, iyo simba chinhu chemidziyo ichave yakaderera kwazvo, uye parallel inverter mutoro ikozvino ndeye square wave, iyo inosvibisa zvakanyanya grid. Kana simba racho richigadziriswa nekugadzirisa inverter back pressure angle, simba rekugadzirisa mararamiro rakanyanya kutetepa. Naizvozvo, parallel inverter magetsi emagetsi haagone kuita imwechete-ku-vaviri kushanda.
