Iwo anoshanda musimboti we2021 nyowani induction inonyunguduka vira

1. Kubva pamufanidzo wedhisheni wedunhu guru re kudonhedzwa kunyorera vira pamusoro, zvinogona kuoneka kuti simba rekugovera chikamu cheiyo induction inonyungudika chirahwe inoumbwa neyemagetsi yekudyidzana inosangana neyechitatu-chikamu AC kunwa; iyo inogadziridza chikamu chinoumbwa netatu-chikamu chakazara chinodzorwa gadziriso bhiriji rinoumbwa neakawanda thyristors, Inoita kuti iro rinoburitsa simba reiyo induction yakanyunguduka vira kuti irambe ichigadziriswa kubva ku0.1Pn (Pn inomiririra iro rakatemerwa simba) kuenda kuPn. Kana ichivharwa kana kutadza uye ichimira kumhanya, iyo inogadzirisa inogona kushandurwa kubva kune inogadzirisa mamiriro ekushandira kuenda kune inverter inoshanda nyika, zvekuti inonyanyo chengetwa muDDC Simba riri mudanho repakati rinopihwa kudzoka kune magetsi emagetsi network. Kuti udzivirire iyo inogadzirisa thyristor, inokurumidza fiyuzi uye DC inodzosera pamusoro pekudzivirira kuchengetedza yakaiswawo mudunhu.

Iyo DC yepakati redunhu inonyatso kuve inoumbwa neyakadziirwa mvura-yakadzipwa neiyo simbi simbi. Basa rayo kusefa iyo pulsating DC kuburitsa yeanogadzirisa uye kudzvinyirira iko kweanopindirana frequency voltage pane yemagetsi gridhi. Kana mutoro wacho wapfupikiswa, inoitawo basa mukudzivirira ikozvino kuti isasimuke nekukurumidza.

Iyo inverter inoumbwa neyechete-chikamu yakazara-kutonga inverter bhiriji inoumbwa neakawanda anokurumidza thyristors. Neimwe nzira yekukonzeresa maristristors, iyo yazvino inoburitswa kune zviteshi zvekuisa iwe uye v zveiyo yakafanana resonant mutoro mune inochinja nzira padanho repakati.

Uye zvakare, iyo dunhu hombe yeiyo induction inonyunguduka chiravira zvakare inosanganisira AC uye DC kutanga macircuit.

2. Kudzora dunhu

Iyo dunhu mune huru yedunhu musimboti dhayagiramu ndiyo inodzora wedunhu yeiyo induction inonyunguduka vira. Kune ichi chikamu, kwakadzama kudzora uye kugadzirisa block dhayagiramu inopihwa. Inogona kuoneka kubva pamufananidzo iyo iyo inogadziriswa yeiyo induction inonyunguduka chirau inodzorwa nezvikamu zviviri: inogadzirisa inogadzirisa uye inogadzirisa inokonzeresa. Shanduka kupomba gudzazwi kudzora.

Iko kukanganisa kuongorora uye kudzivirirwa kweiyo yese induction inonyunguduka vira inodzorwa nechengetedzo yemagetsi uye inverter yekutarisa, uye iwo maratidziro azvino nemagetsi anonyanya kuzadzikiswa neanoratidza mhinduro bhodhi.

Kutanga kweiyo yose induction inonyunguduka choto inopedzwa nekutetemera kwekutetema.

Iko kufambiswa kwezvikamu zvese zviri pamusoro zvinotongwa ne programmable controller (PLC).
