Iyo yepakati frequency induction heating equipment inogona kutangwa asi mamiriro ekushanda haana kunaka. Nzira yekugadzirisa sei uye kugadzirisa nayo?

(1) Dambudziko rechiitiko Midziyo inogona kutanga isina mutoro asi iyo DC voltage haisvike pachiyero chakayerwa, uye iyo DC inotsvedzerera reactor ine impulsive sound uye inoperekedzwa nejitter.

Ongorora uye kubata nekudzima inverter inodzora magetsi, kubatanidza dummy mutoro kune inobuda yebhiriji rekugadziridza, uye nekutarisa kubuda waveform yebhiriji rectifier ine oscilloscope. Zvinogona kuonekwa kuti chikonzero chekushayikwa kwechikamu mune yakabuda waveform ye rectifier bhiriji inogona kunge iri: iyo inoyerera inokonzeresa pulse inorasika; Iyo amplitude ye-trigger pulse haina kukwana uye hupamhi hwakanyanya kutetepa, zvichiita kuti simba rive risina kukwana rinokonzera, izvo zvinoita kuti thyristor ishandurwe uye ichidzimwa nguva dzose; iyo pulse time ye-double-pulse trigger circuit haina kururama kana kupindirana kwemhepo kunoshaikwa;

(2) Dambudziko rechiitiko Midziyo inogona kutangwa zvakajairika uye zvakanaka, uye kana simba richikwira kune imwe kukosha, overvoltage kana overcurrent kuchengetedzwa kunopihwa.

Kuongorora nekugadzirisa zvakakamurwa kuita matanho maviri ekutsvaga chikonzero chekukanganisa: kutanga shandisa midziyo isina mutoro uye ona kana iyo voltage inogona kusimudzwa kune yakarongwa kukosha; kana iyo voltage isingakwanisi kusimudzwa kune yakatemerwa kukosha uye kuchengetedzwa kwepamusoro kuri pedyo nehumwe kukosha kwevoltage kakawanda, iyi inogona kunge iri muripo capacitor Kana iyo yekumira voltage ye thyristor haina kukwana, asi haina kubviswa kuti inokonzerwa nechimwe chikamu chedunhu. Kana iyo voltage inogona kukwira kune yakatemerwa kukosha, mudziyo unogona kuendeswa kune inorema basa rekushanda uye tarisa kana kukosha kwazvino kunogona kusvika kune yakatarwa kukosha; Iyo haigone kusimudzwa kune yakatemerwa kukosha, uye iyo overcurrent kudzivirira iri pedyo nehumwe kukosha kweiyo nguva yakawanda. Uku kungava kukanganisa kukuru kwazvino. Chengetedza zvakanyanya kukanganiswa kweiyo electromagnetic munda wepakati frequency uye yakakura ikozvino pane yekudzora chikamu uye mutsara wechiratidzo.
