The TYD35 series of capacitive voltage transformers are suitable for outdoor neutral point effective grounding systems with a rated voltage of 35kV and a rated frequency of 50Hz for voltage and energy measurement and relay protection, and can also serve as carrier communication;
The TYD35 capacitive voltage transformer is directly introduced from the medium voltage terminal of the capacitive voltage divider and equipped with an electromagnetic unit consisting of an intermediate transformer, a compensating reactor, and damping
Equipment composition;
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. Inject capacitor oil into the porcelain sleeve and install a metal expander to compensate for changes in oil volume with temperature;
The TYD35 capacitive voltage transformer adopts a speed saturation damping device, which has a fast transient response speed and can reliably dampen ferromagnetic resonance;
The secondary outlet box is equipped with a carrier communication terminal and an overvoltage protection gap;
There is an oil level gauge, outlet box, nameplate, drain plug, and grounding seat outside the fuel tank;
The product has optimized the sealing structure and has good sealing performance.
