Choyambitsa mwachindunji cha kutentha kwa PCB kumachitika chifukwa cha zida zamagetsi zamagetsi, zida zamagetsi zimakhala ndi madigiri osiyanasiyana osungunuka mphamvu, ndipo kuthirira kutentha kumasiyanasiyana ndi magetsi.

2 Phenomena ya kutentha kwa kutentha ku PCB:

(1) Kutentha kwakomweko kumakwera kapena kutentha kwakukulu kwa malo;

(2) Kutentha kwakanthawi kochepa.

Powunikira mphamvu ya PCB yamagetsi, mbali zotsatirazi nthawi zambiri zimasanthulidwa:

1. Magetsi amagetsi

(1) Pewani kugwiritsa ntchito mphamvu pagawo lililonse;

(2) Pendani kayendedwe ka mphamvu pa PCB.

2. Kapangidwe ka PCB

(1) Kukula kwa PCB;

(2) Zipangizo.

3. Kukhazikitsa PCB

(1) Njira yokhazikitsa (monga kuyika kolunjika ndi kuyika kwapamwamba);

(2) kusindikizidwa ndi mtunda kuchokera kunyumba.

4. Ma radiation yamafuta

.

(2) Kuchulukitsa kutentha pakati pa PCB ndi malo oyandikana ndi kutentha kwawo kwathunthu;

5.

(1) Ikani radiator;

(2) Kuphatikiza kwina kwa makonzedwe ena.

6. Makina opangira mafuta

(1) Zachilengedwe;

(2) Kukakamizidwa Kuzizira.

Kusanthula kwa PCB kwa zinthu zomwe zili pamwambapa ndi njira yothandiza kuti ithetse kutentha kwa PCB, nthawi zambiri muzochitika ndi dongosololi
