The temperature of the capacitor and the temperature of the shell is limited, but there are some reasons why the temperature of the capacitor is too high:
(1) Because of the unreasonable design of the capacitor chamber, the ambient temperature of the capacitor chamber is too high;
(2) The density of capacitors is too high and the ventilation is poor;
(3) Overcurrent of capacitors caused by overvoltage;
(4) The internal defects of the capacitor, the increase of the dielectric loss and the increase of the calorific value after the aging of the dielectric.
Solution: Stop running capacitors, and then analyze the causes (the four above are common causes) and find the appropriate solution.
