Application scope of high-voltage ceramic capacitors

High voltage ceramic capacitors, also known as high-voltage ceramic capacitors used in power systems, are generally used for metering, energy storage, voltage division, and other products in power systems. High voltage ceramic capacitors have been widely used in the LED light industry and occupy a prominent position. High voltage ceramic capacitors are made by extruding high dielectric constant capacitor ceramics (barium titanate oxide) into circular tubes, discs, or disks. Dielectric, and silver plating is used on ceramics as electrodes by sintering method.
Function of high-voltage ceramic capacitors.
High voltage ceramic capacitors have the characteristics of wear-resistant DC high voltage and are suitable for use in high-voltage bypass and coupling circuits. Low loss high-voltage chips have low dielectric loss and are particularly suitable for circuits such as television receivers and scanners.
High voltage ceramic capacitors only need to be designed for high frequencies. Based on their usage location, their typical function is to eliminate high-frequency interference.
High voltage ceramic capacitors are used in high-power and high-voltage fields, requiring characteristics such as small size, high voltage resistance, and good frequency characteristics. In recent years, with the advancement of materials, electrodes, and manufacturing processes, the development of high-voltage ceramic capacitors has made significant progress and has been widely applied. High voltage ceramic capacitors have become an indispensable component in high-power and high-voltage electronic products.
The main applications of high-voltage ceramic capacitors are power equipment and pulse energy processing equipment in transmission and distribution systems.
Due to the special characteristics of the power system, such as high AC voltage, high frequency, outdoor environment (-40 degrees to+60 degrees), and high lightning voltage/current, high-voltage ceramic capacitors are difficult to use in research and production, always in a dilemma: harsh environments require capacitors to have super strong stability, that is, the rate of change must be small. At the same time, high precision is required for products such as metering, energy storage, and voltage division, which places extremely strict demands on the partial discharge or partial discharge of high-voltage ceramic capacitors in such environments: zero partial discharge.
