LB-10W current transformer   

 

 Description

The type current transformer is a kind of steel tank oiI-immersed type of current transformer  providing current and electric energy measurement and relaying protection to system with the frequency of 50 Hz.
The current transformer carries out the long operation under the conditions for 20%of rated current,lt iS used in the fields of altitude not exceed 4000m,and max.Change of ambient temperature not exceed-25°C~+40°C.

 

Type description

     

Construction

The transformer is made of single-phase oil immersed type self-cooling type,which can be used indoors or outdoors.There are insulation and oil for cool down the transformer insalled inside the transformer.It adopts vacuum oiI-filter and vacuum oiIing arts.The distance between Class 10kV fuel and cover is about 15mm,there is an oiIing valve instaIled above the cover,(there is an air hole on the valve)with water-proof and snow-proof cover.There is an oil tank inside the class 35kV tube.The diaph ragm imside the oil tank can make the oil be seperated from the air.which decreases the oil oxidizing speed.Transformer thermaI stabiIity 187.5 times.The product has four models:Sinale-ratio single secondary,single ratio double secondary,double ratio Single secondary and double ratio double secondary.CT for measurement,it is Class 0.2,CT for continuous protection control,it iS Class 0.2,0.5 and 1.3(D),etc.
