Ungabhekana kanjani ne-overcurrent ye imishini yokufudumeza efrikhwensi ephezulu?

Izizathu zokudlula ngokweqile kwemishini yokushisisa imvamisa ephezulu yilezi:

1. Ikhoyili ye-induction eyenziwe ngokwayo inomumo nosayizi ongalungile, ibanga phakathi kwe-workpiece ne-induction coil lincane kakhulu, kukhona isifunda esifushane phakathi kwe-workpiece ne-induction coil noma i-induction coil ngokwayo, kanye nekhoyili yokungeniswa elungiselelwe. kuthintwa insimbi yekhasimende ngesikhathi sokusetshenziswa noma Ithonya lezinto zensimbi eziseduze, njll.

Indlela:

1. Yenza kabusha ikhoyili yokungeniswa. Igebe lokuhlanganisa phakathi kwekhoyili yokungeniswa kanye nengxenye yokushisa kufanele libe ngu-1-3mm (lapho indawo yokushisa incane), futhi ikhoyili yokungeniswa kufanele ilinyazwe ngeshubhu lethusi eliyindilinga noma ishubhu lethusi lesikwele elinogqinsi luka-1-1.5mm futhi ngenhla φ5;

2. Hlola ukuthi amandla okushisa afana nesivikeli. Uma ukufanisa kunembile, hlola ukuthi ukusebenza kulungile, ikakhulukazi isikhathi sokushisa;

3. Uma izinto ezikwazi ukungena kahle kazibuthe njengethusi ne-aluminiyamu zishiselwa ngendlela eguquguqukayo, inani lamakhoyili okungenisa kufanele lenyuswe;

4. Izinto ezisetshenziswayo kufanele zigweme ukukhanya kwelanga, imvula, umswakama, njll.;

5. Shintsha ekushintsheni kokuvikela okukhulu, inqobo nje uma isistimu yokushisa ijwayelekile.

Okwesibili, ukuqala kabusha kwe-overcurrent

1. Ukuhlukaniswa kwe-IGBT

2. Ukwehluleka kwebhodi lomshayeli

3. Ibangelwa ukulinganisa izindandatho ezincane kazibuthe

4. Ibhodi lesifunda limanzi

5. Ukunikezwa kwamandla kwebhodi lokushayela akujwayelekile

6. Isifunda esifushane senzwa

Indlela:

1. Faka esikhundleni ibhodi lomshayeli kanye ne-IGBT, susa indandatho yamagnetic encane ekuholeni, hlola umzila wamanzi, ukuthi ibhokisi lamanzi livinjiwe, vuthela ibhodi elisetshenziswa ngesomisi sezinwele, futhi ulinganise i-voltage;

2. I-Overcurrent ngemva kokusebenzisa isikhathi esithile ngemva kokuqalisa: isizathu ngokuvamile ukungashisi kahle komshayeli. Indlela yokwelapha: phinda usebenzise amafutha abicah; hlola ukuthi umgwaqo wamanzi uvaliwe yini.

Okwesithathu, amandla akhuphuka ngaphezu kwamanje

1. Ukushisa kwe-Transformer

2. Inzwa ayifani

3. Ukwehluleka kwebhodi lomshayeli

Indlela:

1. Ingaphakathi lomshini kanye nekhoyili yokungeniswa kufanele kupholiswe ngamanzi, futhi umthombo wamanzi kufanele uhlanzeke, ukuze ungavimbi ipayipi lokupholisa futhi ubangele umshini wokushisa nokulimala. Izinga lokushisa lamanzi okupholisa akufanele libe phezulu kakhulu, kufanele libe ngaphansi kuka-45 ℃;

2. Ungasebenzisi itheyiphu yezinto eziluhlaza ezingangeni manzi lapho ufaka ikhoyili yokungeniswa ukuze ugweme ukuxhunywa kukagesi okubi. Ungashintshi i-solder ye-induction ikhoyili ibe yi-brazing noma i-silver welding;

3. Kunezizathu eziningi zokuthonya inani lokuphenduka kwekhoyili ye-induction ku-current, futhi kungase kubangele i-overcurrent.
