110kV LEVEL THREE-PHASE ON-LOAD TAP-CHANGING

ELECTRIC POWER TRANSFORMER

Summary

We have adopted series of important reforms on the 110kV level three-phase oil-immersed on-load tap-changing transformer referring material,
process and structure. The transformer has the features of small size, light weight, high efficiency, low loss, low noise, reliable operation etc,
which can reduce a large amount of power network loss and operation expenses with significant economic beneffts. It is suitable for power plant substation,
heavy section plant ore enterprises etc.

Note 1:-5% tapping position is maximum current tapping.
Note 2: For boost transformer, it is advisable to adopt non-tapping structure. If there is any requirement for operation, sub-connectors can be set up.
Note 3: When the average annual load rate of transformer is between 42% and 46%, the maximum operating efficiency can be obtained by using the loss value in the table.
