Brief Introduction
The"JDCF"series voltage transformers are inducitive type,single phase,oil filled,outdoor type.It accords to the GB 1207-1997<voltage transformer>,IEC 186 and IEC60044,This type of voltage transformer is of cascade full seal construction,The product consists of winding assembly,porcelain housing,transformer oil,base and stainless steel Bellow.
The primary winding of 110KV or 132KV voltage transformer is divided into two parts,wound separately around the upper and lower core,Wound around the lower core,three secondary windings are respectively measuring winding,protective winding and residual voltage winding.
The primary winding of 220KV or 230KV voltage transformer is divided into four parts,wound separately around two cores.Wound around the lower core,three secondary windings are respectively measuring winding.protective winding and residual voltage winding.
The active part is located to the base by suporting frame made of high quality insulation materials and is put into porcelain housing with degassed and de-watered transformer oil after vacuum treatment,All outlet wires of secondary winding and the terminal "N" of primary wnding are connected to the epoxy resin board which is in the waterproof and dust-proof terminal box of the base.There is a valve for oil-filling or oil-exhausting on the base.
