The TYD220-220kV capacitive voltage transformer product consists of two parts: a capacitive voltage divider and an electromagnetic unit. The capacitive voltage divider consists of a ceramic sleeve, a capacitor core, a capacitor oil, and a metal expander, while the electromagnetic unit consists of an intermediate transformer, a compensating reactor, and a damper. This series of transformers adopts a speed saturation damping device, which has a fast transient response speed and can reliably dampen ferromagnetic resonance. The product has optimized the sealing structure and has good sealing performance.
