Toshiba Large capacity gas insulated transformer

Specifications and Ratings

Rising demand for electric power in large cities has encouraged large- scale substations to be tucked away underground in overpopulated urban

areas, leading to strong demand for incombustible and non- explosive, large- capacity gas insulated transformers from the view point of accident

prevention and compactness of equipment.

In line with this requirement, several types of large- capacity gas insulated transformer have been

developed.

The gas- forced cooling type was considered to be available for up to approximately 60MVA, while all other gas insulated transformer with

higher ratings are liquid cooled.

But the liquid cooling type has the disadvantage of a complex structure for liquid cooling.

Thus, TOSHIBA

began development of gas forced cooling type gas insulated transformer, making best use of accumulated experience, latest analyzing technique

and the results of innovative research activities.

As a result, TOSHIBA has delivered 275kV- 300MVA gas cooled and gas insulated

transformer, of which its structure is as simple as the oil immersed type and is the largest capacity gas insulated transformer in the world.

Realization of gas insulated transformer

Since heat capacity of SF6 gas is much smaller than that of insulating oil, the following measures are taken into account.

1 - Raise the SF6 gas pressure to 0.5MPa

2 - Produce as large flow as possible by optimizing the layout of gas ducts in the windings

3 - Develop high capacity gas blower with high reliability

4 - Apply highly thermal- resistant insulating materials to raise the limit of winding temperature rises
