• Capacitor voltage Transformer(abbreviate:CVT))is composed of a Shunt of a composed capacitor device and a electromagnetic unit.
• Capacitor shunt device
CTVis composed ofhigh voltage capacitor and medium voltage;apacitor, which is sited inner ceramic conduit and the conduit is filled with insulation oil
• Electromagnetic Unit
The electromagnetic unit is composed of midway transformer reactor compensator damper and lightning arrester inside the oil tank the terminals ofsecond oil CVD low voltage terminals grounding terminals and protective clearances are inside the terminal box.
• Oil sealing
The capacitor elements ofCVD are sealed inner ceramic conduit whichis processed with procedures of heating, vacuum dried and filling with de-hydraulic and air-free insulation oil and keep the vacuum then The oil volume variation out of temperature changing shall be adjusted through the expansion box outside the upper side ofthe ceramic conduit, so as to keep the positive oil pressure inside stable at 0.0005~0.05/cm?
