 LAZBJ-10 current transformer

Description and meaning of model

This type of transformer is to wear the wall epoxy resin cast fuly enclosed structure.For the rated  frequency 50Hzrated voltage of 10kV and below the line for energy measurment and relay protection .

This type of transformer with high dynamic and thermal stability,high accuracy full working  condition condensing type epoxy resin casting and so on.To facilitate the interchangeability.Be improved on the basis of the original LAJ-10 package size unchanged for energy measurment and protection monitoring for switchgear and metering cabinet,is a good power management necessary equipment.

Characteristic of structure

LAZBJ-10 type current transformer is completely closed casting resin structure.High tension coil forming the epoxy resin cast mold positioning,core made quailty cold-rolled silicon steel sheet around the ring,the secondary therminal on the sidewall next to the secondary terminals marked with1$1,1$2and 2$1,2$2,corresponding to the measurement,protection level.
