The physical mechanism of CVT ME is as follows: From Fig. 1, the high voltage U p on the primary side is divided into medium voltage by the CVD, and then the medium voltage is reduced into the low voltage output U s by the IVT. Since the high voltage U p is stepped down by the CVD, the insulation requirement for the IVT is reduced. The CVD is composed of hundreds

Customer ServiceThe effectiveness of water cooling is dependent on the properties of the water used. The water for use in water cooled capacitors should be chemically neutral, mechanically pure, and its electrical conductivity should not exceed the value specified by the manufacturer, typically 500µS/cm.
The water for use in water cooled capacitors should be chemically neutral, mechanically pure, and its electrical conductivity should not exceed the value specified by the manufacturer, typically 500µS/cm. The performance characteristics of water cooled capacitors are significantly dependent on the stability of the cooling water supply system.
In most modern water cooled capacitors, the cooling medium passes through the interior of the component. These modern water-cooled capacitors are more efficient compared to their predecessors. There are various ways of achieving cooling in water cooled capacitors. The most commonly used designs are transverse cooling and foil cooling.
Due to the influence of aggregate capacitance output characteristics, when the moisture content is greater than 1.0%, the capacitance output change is not obvious, so the capacitive moisture content detection method is more suitable for micro water detection, that is, to evaluate the level of inner water in aggregate.
Capacitors with integrated water cooling systems are suitable for such applications. Using water cooled capacitors also helps to reduce the cost and the number of components used. Film and ceramic capacitors with integrated liquid cooling systems are increasingly becoming popular for high-current applications.
Capacitors for use in high-power and high-frequency applications are cooled using various methods. The most common cooling methods include self-cooling, forced ventilation, and liquid cooling. These methods are all aimed at ensuring that the temperature of a capacitor is maintained within the acceptable limits.
