Currently, self-healing power capacitors are mainly applied in low voltage cases. This is because that the geometry of the self-healing capacitor is not the most optimized solution. If the high voltage is applied, the temperature rise is significant. The lifetime of self-healing power capacitor is shortened.
From the typical waveform, it can be seen that during the self-healing process, the voltage across the specimen remains basically constant due to the presence of the shunt capacitor, and the duration of the self-healing current is about 1–2 μs. Based on the experimental waveform and Eq. (1), the self-healing energy E sh can be calculated.
A self-healing capacitor group with a rated voltage of 11/ 3 kV and a capacity of 334 kvar is designed and optimized. The temperature rise of the capacitor is appreciably reduced. The results agree well with the above conclusions.
As a result, the geometric optimization of self-healing capacitor should be studied further. To investigate the geometric optimization of self-healing capacitor systematically, the temperature distribution simulation model of self-healing power capacitors with different elements orientations are formulated in Fluent15.0.
