TYD110 series high-voltage transformerDetailed product description：

The TYD110 series high-voltage transformer is an outdoor product consisting of a capacitive voltage divider and an electromagnetic unit. It is suitable for voltage and energy measurement relay protection in neutral point effective grounding systems with a rated voltage of 110kV and a rated frequency of 50Hz.



3、 Structure Introduction and Product Features
The TYD110 series high-voltage transformer consists of a capacitive voltage divider and an electromagnetic unit. The medium voltage terminal and low voltage terminal of the capacitive voltage divider are directly introduced into the oil tank containing the electromagnetic unit. The electromagnetic unit consists of an intermediate transformer, a compensating reactor, and a damper. The capacitive voltage divider consists of a ceramic sleeve, a capacitor core, capacitor oil, and a metal expander. The capacitor core is composed of several film paper composite media and aluminum foil wound components connected in series, and is subjected to vacuum impregnation treatment. Equipped with a metal expander to compensate for changes in oil volume with temperature. The secondary junction box is equipped with carrier communication terminals and overvoltage protection gaps.
The mutual inductance 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.
