The kudonhedzwa kunyorera vira haigone kushanda zvakajairwa mushure mekutanga, kazhinji inoratidzwa mune zvinotevera zvinhu:

1. Kurasikirwa kwechikamu chemugadziri: Mhosva inoratidzwa seruzha rusina kujairika panguva yekushanda. Iyo yakakura kubuda voltage inokwira pasi peiyo yakatemerwa kukosha. Kana iyo kabati yemagetsi ichiburitsa ruzha rusina kujairika, magetsi ekubuda anogona kudzikiswa kusvika pa200V, uye kubuda kweanogadzirisa kunogona kutariswa neoscilloscope Voltage waveform (iyo oscilloscope inofanirwa kuiswa mumagetsi). Kana iyo yekuisa voltage waveform yakajairika, kune matanhatu mafungu padenderedzwa, uye maviri anorasika kana chikamu chisipo. Kukanganisa kwerudzi urwu kunowanzo kukonzerwa nevamwe vanogadzirisa. Chete thyristor haina trigger pulse kana trigger haina kuvhurwa. Panguva ino, unofanira kushandisa oscilloscope kuona gedhi pulses matanhatu akagadziridzwa thyristors. Kana zvirizvo, ndapota shandisa multimeter kuyera kushorwa kwegidhi yega yega pazasi 200Ω mushure mekunge yadzimwa, ichavharika, kana kristaro ine yakanyanya kukwirisa grid resistance inongoda kutsiva brake chubhu.

2. Inverter matatu mabhiriji maoko anoshanda: iyo inobuda ikozvino yakakura kwazvo, choto chakafanana kana choto chisina chinhu, iyo kabati yemagetsi inonzwika zvakanyanya panguva yekushanda, uye inoratidzika seyakakanganisa. Mushure mekutanga, shandura iyo knob yemagetsi kune diki chinzvimbo, uye iwe unowana iyo induction inonyungudutsa choto Iyo inobuda voltage yakakwira kupfuura yakajairika nhanho. Shandisa oscilloscope kuona voltage waveform pakati peanode uye cathode yeina inverter thyristors. Kana maoko matatu ebhiriji ari kushanda, unogona kuona kuti maviri ari pedyo thyristors ari inverter achabudisa mafungu. .

3. Induction coil kukundikana: Iyo induction coil ndiyo mutoro weiyo induction inonyungudika choto. Yakagadzirwa nesquare copper tube ine madziro emadziro e3 kusvika ku5 mm. Izvo zvinowanzoitika zvinokundikana ndezvizvi:

Iyo induction coil inodonhedza mvura, izvo zvinogona kukonzera moto pakati pekoiri inotendeuka, saka inofanirwa kugadziriswa nenguva. Simbi yakanyungudutswa inonamira kune induction coil uye simbi slag inopisa uye yakatsvuka, izvo zvinozoita kuti chubhu yemhangura inopisa. Inofanirwa kucheneswa nenguva, uye iyo induction coil ipfupi-inotenderera. Kukundikana kwerudzi urwu kunonyanya nyore kuitika mumavira madiki ekunyungudika, nekuti choto idiki uye chinopisa panguva yekushanda.

Pamusana pekugadzirisa kunokonzerwa nechisimba, pfupi pfupi pakati pekutendeuka inokonzerwa. Mhosva inoratidzwa seyepamusoro ikozvino uye yakakwirira yekushanda frequency pane yakajairwa. Muchidimbu, kuitira kuti ugone kushandisa nzira yakarurama yekugadzirisa kukanganisa kwechoto chekunyunguduka kwemoto, unofanira kunge uchiziva induction Maitiro uye zvikonzero zvekukundikana kwakajairika kwevira rekunyunguduka, kuitira kuti udzivise kutsauka, kuchengetedza nguva. , gadzirisa dambudziko nekukasira, uye udzorere zvakajairika kushanda kweiyo induction yekunyungudutsa choto, kuitira kuti uve nechokwadi chekufambira mberi kwakanaka kwekugadzira.
