Detailed introduction

MKKThe capacitor has a self-healing function. It uses a dry winding and is installed in an aluminum cylinder. Its dielectric is a low-loss metallized polypropylene film. Due to the use of new technology in the manufacture of windings, the performance of capacitors has been greatly improved. The capacitor is composed of three groups of capacitors, which are electrically insulated from each other and arranged concentrically on the aluminum die core. The three groups of capacitors can be star-connected or delta-connected. The structure and test of the capacitor are as followsEN60831-1Proceeds. Due to the dry structure, the capacitor can be installed in any place, and its internal protection gas (nitrogen) is non-flammable.

MKKCapacitors are equipped with over-pressure expansion fuses. If the fault point repeatedly self-healing, resulting in the internal pressure rise and reach a certain value, the expansion fuse that action. At this time, the fuse is broken at the designed break. The expansion fuse can safely disconnect the capacitor from the power system.
