How to improve the life of high voltage capacitors
How to improve the life of high-voltage capacitors is a topic that we have always been concerned about. According to this topic, I will tell you about the life of high-voltage capacitors. As long as you understand the factors that determine the life of high-voltage capacitors, you can carry out targeted maintenance and improve the lifespan.
1) Current capability: Large overcurrent, long life of the capacitor
2) Partial discharge: This is the bottleneck of many domestic manufacturers. The larger the size, the harder it is to handle partial discharge.
But after our long-term market practice, we found that the more the partial discharge is connected to 0PC, the better the performance and life in all aspects. For example, in the high-frequency pulse circuit, the partial discharge is small, and the ability to withstand high-frequency pulses is stronger. Longer life
3) Frequency characteristics: The frequency characteristics are often determined by the capacitor’s medium, which means that no matter whose product is used, as long as the same ceramic medium is used, the frequency characteristics of the capacitor are the same. For the same reason, use more A porcelain manufacturer with good frequency characteristics will have a longer lifespan for his capacitors, so pay attention to the choice of materials when choosing capacitors.
4) Voltage level: usually the voltage of the CT8G series capacitors we marked on the high-voltage ceramic capacitors refers to DC voltage, but in practical applications, military products use DC voltage, and the power industry uses AC voltage. Judgment The life or quality of a capacitor, we can first judge from the voltage, whether it is used in military, civilian, or industrial use, everyone should remember that only capacitors with high AC voltage levels, the life of high-voltage capacitors is equal to Indirect cost savings, so we need to understand the source of the factors to solve the problem.
