Momwe mungathanirane ndi overcurrent ya Kutentha kwapafupipafupi?

Zifukwa zochulukirachulukira kwa zida zotenthetsera zothamanga kwambiri ndi izi:

1. Coil yodzipangira yokha ili ndi mawonekedwe olakwika ndi kukula kwake, mtunda pakati pa chogwirira ntchito ndi koyilo yolowera ndi yaying’ono kwambiri, pali kagawo kakang’ono pakati pa chogwirira ntchito ndi coil induction kapena coil induction palokha, ndi koyilo yopangira induction. imakhudzidwa ndi chitsulo cha kasitomala pakugwiritsa ntchito kapena Chikoka cha zinthu zachitsulo zapafupi, etc.

Njira:

1. Panganinso koyilo yolowera. Kusiyana kolumikizana pakati pa koyilo yolowera ndi gawo lotenthetsera kuyenera kukhala 1-3mm (pamene malo otenthetsera ndi ochepa), ndipo koyilo yolowera iyenera kuvulazidwa ndi chubu chamkuwa chozungulira kapena chubu chamkuwa chokhala ndi makulidwe a 1-1.5mm. pamwamba φ5;

2. Onani ngati mphamvu yotenthetsera ikufanana ndi chitetezo. Ngati machesi ali olondola, fufuzani ngati ntchitoyo ndi yolondola, makamaka nthawi yotentha;

3. Zida zokhala ndi maginito osakwanira bwino monga mkuwa ndi aluminiyamu zimatenthedwa movutikira, kuchuluka kwa ma koyilo olowera kuyenera kuchulukidwa;

4. Zidazi zipewe kuwala kwa dzuwa, mvula, chinyezi, ndi zina;

5. Sinthani ku chotchinga chachikulu choteteza, pokhapokha ngati chowotcha chimakhala chachilendo.

Awiri, kuyambitsa mopitirira muyeso

1. Kuwonongeka kwa IGBT

2. Kulephera kwa board board

3. Zimayambitsidwa ndi kulinganiza mphete zazing’ono zamaginito

4. Bwalo lozungulira ndilonyowa

5. Mphamvu yamagetsi ya board board ndi yachilendo

6. Dera lalifupi la sensa

Njira:

1. Bwezerani bolodi la dalaivala ndi IGBT, chotsani mphete yaing’ono ya maginito kuchokera kutsogolo, yang’anani njira yamadzi, ngati bokosi lamadzi latsekedwa, kuwombera bolodi logwiritsidwa ntchito ndi chowumitsira tsitsi, ndikuyesa magetsi;

2. Overcurrent pambuyo ntchito kwa nthawi pambuyo booting: chifukwa zambiri osauka kutentha dissipation wa dalaivala. Njira yothandizira: perekaninso mafuta a silicone; onani ngati njira yamadzi yatsekedwa.

Chachitatu, mphamvu ikuwonjezeka kuposa panopa

1. Kuyatsa kwa Transformer

2. Sensa sichikugwirizana

3. Kulephera kwa board board

Njira:

1. Mkati mwa makina ndi coil induction ayenera kuziziritsidwa ndi madzi, ndipo gwero la madzi liyenera kukhala loyera, kuti lisatseke chitoliro chozizira ndikupangitsa makinawo kutenthedwa ndi kuwonongeka. Kutentha kwa madzi ozizira sikuyenera kukhala kokwera kwambiri, kuyenera kukhala kochepa kuposa 45 ℃;

2. Osagwiritsa ntchito tepi yazinthu zopanda madzi pakuyika koyilo yolowera kuti mupewe kulumikizidwa koyipa kwamagetsi. Osasintha ma coil soldering kukhala brazing kapena kuwotcherera siliva;

3. Pali zifukwa zambiri zomwe zimakhudzira kuchuluka kwa kutembenuka kwa coil induction pakali pano, komanso kungayambitse kupitilira.
