TYD-35/66/110/220kV high capacitor voltage transformer
Summary
It is outdoor,single phase and oil capacitor voltage transformer,which is used for metering and relay protection of 35~220kv,50hz system.its capacitor divider is also used as coupling capacitor in carrier wave coupling device in power line unit.
Structure feature
consists of capacitor voltage divider and electromagnetic unit The capacitor divider is making up of one or several coupling capacitors to series H.V. terminal is at top of capacitor divider. Medium and low voltage terminal is in electromagnetic unit for leading from magnetic on lowest H.V. capacitor chassis Neutral transformer, compensation reactor and damper are filled in the tank, it makes up electormagnetic unit. Transformer oil is filled in the tank and sealed. Volume of oil and internal pressure are adjusted by air at top of tank. Neutral transformer primary side coil can regular coil and voltage error. Compensation reactor regular coil can regular error of phase, secondary winding come out from wiring terminal box of tank front
