Product Description

JDJJ2-11 Model outdoor Oil-Immerse Potential Transformer
Product Description
General Summary:

Application
Series JDJJ2 of non-earthed voltage transformer is single-phase, oil-immersed. It's designed for voltage, electric energy measurement and relay protection in a ineffectively earthed neutral point power system with rated frequency of 50Hz and rated voltage of 11kV.

Service Condition
  • Altitude: up to 1000m above sea level;
  • Ambient temperature: -25ºC to +40ºC;
  • Relative humidity: 85%,at 20ºC
Construction
The voltage transformer is single-phase, three-winding and core type. The active parts are attached to tank cover and put in square oil-tank. The terminals of windings are led out of tank through HV and LV bushings respectively. The conservator is located on the top of HV bushing on which primary terminal is fixed and provided with rubber diaphragm inside to avoid oil from contacting with air. The conservator is fitted with oil level gauge. The tank is provided with drain valve at bottom and mounting holes on the base for fixing. Oil tank and bushing, filled with transformer oil is oilpaper-insulated structure and the conservator is.
