High-voltage ceramic capacitors have the characteristics of wear-resistant DC high voltage, and are suitable for high-voltage bypass and coupling circuits. The low-loss high-voltage wafers have low dielectric loss and are particularly suitable for use in television receivers and scanning circuits.
As long as the high-voltage ceramic capacitors are targeted at high frequencies, the high-voltage ceramic capacitors depend on what is used, and the typical role can eliminate high-frequency interference.
High-voltage ceramic capacitors used in high-power, high-voltage fields require small, high withstand voltage and good frequency characteristics. With the progress of materials, electrodes and manufacturing technology in recent years, the development of high-voltage ceramic capacitors has made great progress and has been widely used. High-voltage ceramic capacitors have become one of the indispensable components of high-power high-voltage electronic products.
The use of high-voltage ceramic capacitors is mainly divided into power equipment for power transmission and distribution systems and equipment for processing pulse energy.
Because of the special characteristics of the power system: high AC voltage, high frequency, outdoor environment (-40 degrees to +60 degrees), high lightning voltage / current, etc. Has been in a difficult situation: the harsh environment requires capacitors to have super stability, that is, the rate of change is small; at the same time, products such as metering, energy storage, and voltage division require high precision. The partial discharge, that is, the partial discharge volume has extremely strict requirements: the partial discharge is zero. [1]
