JSJW-3,6,10 Indoor Voltage Transformer 6kV Voltage Transformer 10kV Voltage Transformer
The iron-core of this voltage transformer employs side-iron structure, made of stripe
silicon steel plate. Every phase has three windings: residual voltage winding,
secondary winding and primary winding. The wiring diagram, please refer to
Diagram 3-1-22. The residual voltage winding is wound onto an insulated paper
sleeve and wrapped with insulated paper board, the secondary winding is wound
onto the paperboard, then wound the primary winding onto the square ring outside
of the secondary winding. The outer of the primary winding has electrostatic shield
respectively and wrapped with paperboard and cloth. The three phases of A,B and C
totally have three winding, wound onto three iron poles of the iron-core.
The transformer is fixed on the cover of tank by clamp, the cover of tank has high-
and low-voltage output porcelain sheathes, nameplate, hanger and oil-feed plug
with inhale hole. The circular barrel shaped oil tank is welded with steel plate and has
a hanger on the upper wall of the tank for lifting up the transformer, the lower wall
of the tank has grounding bolt and oil-discharge plug. The octagonal bottom of tank
is made of steel plate and has four installment holes.
