Yintoni enokuyenza ukuba i-high-frequency izixhobo zokufudumeza ine-overcurrent

Okokuqala, yenza kucace ukuba ingqiqo yoyilo lomatshini wokufudumeza ophezulu we-Tongcheng, ekubeni inkqubo ye-alamu yenzelwe, kufuneka ibe nentsingiselo kunye nexabiso layo. Isiqalo esisisiseko sesi silumkiso sesixokelelwano kukuba,

A. Ibonisa ukuba kukho ukungaphumeleli, nceda umise umatshini ngokukhawuleza ukwenzela ukulungisa ingxaki.

B. Bonisa inqaku lesiphoso, unokukhawuleza ukugqiba indawo yesiphoso, kwaye unike uncedo lokugcinwa. Ke ngoko, xa i-alam isenzeka, nceda umise umatshini ukuze uhlolwe kwaye uxazulule kwangethuba ukunqanda ilahleko enkulu.

Izinto ezibangela ukugqithisa ngokweqile:

I-coil ye-self-made induction inemilo kunye nobukhulu obungalunganga, umgama phakathi kwe-workpiece kunye ne-coil induction incinci kakhulu, kukho isiphaluka esifutshane phakathi kwe-workpiece kunye ne-coil induction okanye i-coil induction ngokwayo, kwaye i-coil induction induction ichaphazelekayo. ngentsimbi yomthengi ngexesha lokusetyenziswa okanye isondele kuyo. Impembelelo yezinto zetsimbi, njl.

Indlela:

1. Yenza kwakhona i-coil induction, i-gap yokudibanisa phakathi kwe-coil induction kunye nenxalenye yokufudumala kufuneka ibe yi-1-3mm (xa indawo yokufudumala incinci)

Kucetyiswa ukuba kusetyenziswe ityhubhu yobhedu ejikelezileyo okanye ityhubhu yethusi yesikwele enobunzima be-1-1.5mm nangaphezulu kwe-φ5 ​​umoya we-coil induction.

2. Sombulula isiphaluka esifutshane kunye nokutshisa i-coil induction

3. Xa imathiriyeli enokungenwa kakuhle kwemagnethi efana nobhedu kunye ne-aluminiyam ifudunyezwa ngokucokisekileyo, inani leekhoyili zokungeniswa kufuneka linyuswe.

4. Isixhobo kufuneka siphephe ukukhanya kwelanga, imvula, ukufuma, njl.

Jonga ukuba amandla okufudumeza ahambelana nomkhuseli. Ukuba umdlalo uchanekile, khangela ukuba umsebenzi uchanekile na, ingakumbi ixesha lokufudumeza.

5. Tshintshela kwisitshixo esikhulu somkhuseli, ngaphandle kokuba inkqubo yokufudumala iyinto eqhelekileyo

C. Ukuqalisa ngokugqithisileyo: Izizathu ziqhelekile:

1. Ukuqhekeka kwe-IGBT

2. Ukungaphumeleli kwebhodi yomqhubi

3. Ibangelwa ukulinganisa amakhonkco amancinci amancinci

4. Ibhodi yesekethe imanzi

5. Ukunikezelwa kwamandla ebhodi yokuqhuba akuqhelekanga

6. Isiphaluka esifutshane senzwa

Indlela:

1. Faka indawo yebhodi yomqhubi kunye ne-IGBT, susa i-ring magnetic encinci kwi-lead, khangela umzila wamanzi, nokuba ibhokisi yamanzi ivaliwe, vuthela ibhodi esetyenziswe ngesomisi seenwele, kwaye ulinganise umbane.

2. I-Overcurrent emva kokusetyenziswa ixesha elithile emva kokuqalisa: isizathu ngokuqhelekileyo kukutshabalalisa ubushushu bomqhubi. Indlela yonyango: phinda usebenzise igrisi ye-silicone; khangela ukuba indlela yamanzi ivaliwe na.

D. Ukonyuka kwamandla ngaphezu kwangoku:

(1) Umlilo we-transformer

(2) Inzwa ayihambelani

(3) Ukungaphumeleli kwebhodi yokuqhuba

Indlela:

1. Ingaphakathi lomtshini kunye ne-coil induction kufuneka ipholile ngamanzi, kwaye umthombo wamanzi kufuneka uhlambuluke, ukuze ungavimbeli umbhobho wokupholisa kwaye ubangele ukuba umatshini ugqithise kwaye wonakalise.

Ubushushu bamanzi okupholisa akufunekanga bube phezulu kakhulu, kufuneka bube ngaphantsi kwe 45℃.

2. Musa ukusebenzisa i-tape yezinto eziluhlaza xa ufaka i-coil induction ukuphepha uxhulumaniso olubi lombane

Musa ukutshintsha i-coil soldering ye-induction kwi-brazing okanye i-solder yesilivere!

3. Kukho izizathu ezininzi zempembelelo yenani lokujika kwe-coil induction kwi-current, kwaye iya kubangela i-overcurrent.

Okokuqala, inxulumene nezinto eziphathekayo ze-workpiece;

Okwesibini, ukuba ikhoyili inkulu kakhulu, i-current iya kuba yincinci;

Kwakhona, i-coil incinci kakhulu, ngakumbi inani lokujika ikhoyili, incinci yangoku iya kuba.
