Basic Info.
Product Description
Capacitor voltage transformer series products are suitable for current, electric energy measurement and relay
protection in a system with effectively earthed neutral with rated voltage 35kV, 66kV, 110kV or 220kV and rated
frequency 50Hz. It can also be used for carrier wave communication concurrently.
This product consists of capacitor voltage divider and electromagnetic unit the medium voltage terminal and low
voltage terminal of capacitor voltage divider are lead out into an oil tank equipped with electromagnetic unit. The electromagnetic unit consists of middle transformer, a compensation reactor and a damper.
The capacitor voltage divider consists of a bushing, a core and a metal expander. The core of capacitor is
combined by several film-paper composite media and serial parts which are made by coiling aluminum foils, it is
carried out vacuum dipping treatment, the porcelain bushing is filled with transformer oil, and it is equipped with
the metal expander to compensate the change of oil volume at different temperatures.
This series transformer has a quick saturation damping device with a quick transient response speed, and it
also can damp ferroresonance reliably.
There is a carrier wave communication terminal in the secondary outlet box, and it also has an over-voltage
protection clearance.
There are an oil level gauge, an outlet box, a nameplate, an oil-discharge plug and an earthing base outside
the oil tank.
The sealing structure of product is optimized, so it has a good sealing performance.
