3.3.3. If detuning low voltage series reactor is installed at the front end of the capacitor, the rated voltage of the capacitor should be selected as below: If the reactance rate of the reactor is 6% or 7%, the rated voltage of the capacitor should be 0.45kV or 0.48kV, if the reactance rate of the reactor is 12% or 14%, the rated
Unfortunately, this mechanism can be dificult to control, and in the worst case, a run-away process can result, causing the destruction of the entire capacitor in short order. To avoid this, KYOCERA AVX developed a controlled self-healing process in 1974 based on the segmentation of overall capacitance into elementary cells protected by fuse gates.
Catastrophic failures and associated explosions or fires are unacceptable. Just as importantly, service lifetime and predictability for optimizing up-time are critical to the product's success. Film capacitors with controlled self-healing are the ideal solution to these challenges and can be obtained in various sizes and technical specifications.
The biggest benefit of organometallic film capacitors is that they are self-healing, which makes these capacitors one of the fastest growing capacitors today. There are two different mechanisms for self-healing of metalized film capacitors: one is discharge self-healing; the other is electrochemical self-healing.
In high voltage, high energy applications such as electric trains and solar power grids, the safety and reliability of capacitors are paramount. Catastrophic failures and associated explosions or fires are unacceptable. Just as importantly, service lifetime and predictability for optimizing up-time are critical to the product's success.
High voltage capacitors for energy storage are generally divided into two distinct technologies: aluminum electrolytic and metal film. Electrolytic capacitors rely on an aluminum oxide dielectric grown on aluminum foil electrodes to form the basic structure.
Aluminum electrolytics tend to be cost-efective in applications requiring high capacitance values at DC voltages less than 800V. These applications include DC-DC converters, motor starters, and frequency converters. When higher voltages are required, especially in non-polarized AC circuits, metal film capacitors are the only alternative option.
