Inappropriate temperature and voltage effects on film capacitors (2)

Putting into operation at a temperature lower than its allowable low temperature, it is likely to cause partial discharges inside the capacitor, thereby accelerating its electrical aging and reducing the actual life of the capacitor. On the other hand, if the film capacitor is operated longer than its high allowable temperature, it will accelerate the thermal aging of the capacitor. Therefore, on the one hand, the capacitor whose temperature category is suitable for the actual operating environment temperature should be selected. On the other hand, the installation, use and use of the capacitor must pay special attention to the problem of ventilation, heat dissipation, and radiation of the capacitor under practical operating conditions. The heat generated in the operation can be emitted in a timely manner to reduce the temperature of the dielectric inside the capacitor under high temperature conditions so as to achieve the purpose of extending the actual service life of the capacitor.
