Hunhu hwehunyanzvi hwe kudonhedzwa kunyorera vira, zvidziviriro zvekushandisa, kuchengetedza uye kurapwa kwekukurumidzira

Rega ndizvizivise kune wese.

A. Chengetedzo yekushandiswa kwechoto chekunyungudutsa induction

1. Tarisa uone kana zvikamu zvese zviri muchimiro chakanaka;

2. Tarisa uone kana zvisungo zvese zviri muchimiro chakanaka;

3. Tarisa uone kana zvakakochekera zvese zvadonha, uye kana majoini akatengeswa asina kunyungudika;

4. Tarisa kana kubatanidzwa mukuiswa kwakarurama;

5. Shandisa multimeter kuti utarise dunhu guru, kuvharwa kwekasi uye kuvhara pakati pezvikamu zvekugadzirisa dunhu;

6. Tarisa kana iyo control plug-in yakaiswa munzvimbo chaiyo;

7. Vhura vharuvhu yekupinza mvura, gadzirisa kudzvanywa kwemvura kusvika pa 0.1～0.2Mpa, uye tarisa kana paine kuvuza munzira yega yega yemvura;

8. Nyatsotarisa kutevedzana kwechikamu, moto wekunyunguduka uri 120 ° mberi kwechikamu chepakati chemasimba emagetsi, uye chigadziko chekubata chiri 120 ° shure kwechikamu chemagetsi chepakati;

9. Shingairira kutonga uye kushandura simba, chiratidzo chesimba chega chega chekutonga chinofanira kunge chiri;

10. Shandisa oscilloscope kutarisa kuti zvinokonzeresa pulses rectification uye inverter inofanira kunge yakajairika;

11. The thyristor yekudzivirira inotangwa, uye chiratidzo chekudzivirira chinoenderana chinovhenekera;

12. Isai simba rekugadzirisa potentiometer panzvimbo ye0, dhonza kunze kwebhodhi rekutonga, uye chengetedza kuti chiito chekudzorera chinofanira kuva chemazuva ose. To

B. Unyanzvi hunoita hwe induction melting virace

Iyo induction yekunyungudutsa choto inotora iyo “yakatevedzana inverter thyristor yepakati frequency magetsi emagetsi tekinoroji”. Kunyangwe iyo thyristor inodzorwa zvizere rectifier yemagetsi vira inoshandiswa, haishandise iyo kugadzirisa voltage. Iyo inongoshandisa iyo kuti iwane yakapfava kutanga uye kuita seyemagetsi switch kana yatadza kukurumidza kudzima magetsi. Paunenge uchishanda, thyristor inogara iri mumamiriro ekugadzirisa zvakakwana, kuitira kuti magetsi emagetsi ane simba guru uye anoderedza kupindira kweharmonic. Iyo rectifier control circuit inotora dhijitari yekuchinja inokonzeresa wedunhu. Iyo yedhijitari yekuchinja inokonzeresa yedunhu ine zvakanakira kudzokororwa kwakanaka, kugadzikana kwakanaka, symmetry yakanaka, kugona kwakasimba kwekurwisa-kupindira, uye kugadzirisa kwakaringana. Kana iyo yedhijitari yehuwandu yekumisikidzwa yakagamuchirwa, inogona kuramba ichiona kure kure. Kupfupisa, iyo induction yakanyunguduka choto choto chinonyunguduka chine simba rakakwirira. Nokudaro, kuti tiwedzere simba rayo repamusoro, tinofanira kuchenjerera kune mamwe maitiro ekushandisa kwayo uye maitiro ayo akasiyana-siyana. Kuti unyatso kutamba basa repamusoro rekunyunguduka kwayo, pamwe chete nekudzivirira kunoshanda kweiyo nguva yekushandiswa kweiyo yepakati frequency furemu.
