Iron core
The core is cold rolled silicon steel sheet with high permeability magnetic grain orientation. The iron core is a core type iron core, the full oblique joint stacking type iron core, the iron core column is a multi-step circular cross-section, the iron bar and the iron core are equal cross-section.
winding
The winding adopts corrugated oil channel, no paint dipping process, and tight tape binding; The windings are concentric coils: the high voltage winding has a tap required for the tap voltage, which is led to the tap switch, the switch is installed on the box cover, and the voltage transfer of 10kV and 20KV can be achieved after the power is cut off, and the tap voltage is changed.
Safety protection device
30~2000kVA transformer equipped with pressure relief valve:
Gas relays with alarm and tripping terminals can be installed according to user requirements; |
