Abstract: Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions. These SH events have the potential to inflict damage on both the polypropylene (PP) film and the electrode layer.
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.
RP serves as a valuable tool for evaluating the safety of MFCs with an unknown SH history, contributing to the assessment of their reliability. Metallized film capacitors (MFCs) are known for their self-healing (SH) properties, enabling efficient and reliable operation, even under challenging conditions.
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.
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 seen from analysis in Section 2.2, the capacitor power loss mainly consists of two parts: dielectric loss in insulation film and electrode loss in electrode (Zinc). The dielectric loss depends finally upon the insulation film itself. With the exception of applicability of the better film, it is hard to decrease dielectric loss further.
