Three Phase AC Filter Capacitor



Application

These capacitors are for use on AC/DC power converters and inverters (drives) that are very common today in the field of power electronics. Traction drives, wind power converters and solar inverters are examples of those applications. Capacitors are usually used in AC filters but also non-sinusoidal and pulsed currents are suitable for them.

Construction

Self-healing process, technology MKP and special metallizing patterns ensure low stray inductance and subsequently very high reliability. Capacitor elements are enclosed in Al cylindrical case filled with non toxic soft resin. Overpressure disconnector assures safe operation and right disconnection at the extreme conditions (high temperature, overloading) and at the end of operating life. Single phase units are usually equipped with two M6 or M8 bolts and three phase units with plastic terminal. Discharge resistors are not used.

Installation instruction

Capacitors should be mounted in vertical position. Max torgues are mentioned in table below. Flexible connection cables have to ensure movement of the capacitor top about 20 mm due to right function of the overpressure disconnector.
