Single Phase Oil Immersed Transformer

Normal standard configuration:

The transformer tanks are all cylindrical sealed structure, all transformers are grounded

Hooks and hooks, US standard mounting slings, pressure relief valves. One (or Two) high-pressure bushings are led out at the cover, and the low-pressure bushings are led out at the wall of the box.

There are bolted terminal blocks with holes. The high voltage tap changer should be turned off

In the case, follow the adjustment position indicated on the nameplate.

Full white protection standard configuration:

The transformer is fully self-protected and protects itself from lightning, short-circuit and overload.

The self-protection system can protect the transmission and distribution lines from failure of the transformer itself.

And causing power failure, its structural features are the same as ordinary ones, such as

Cylindrical fuel tank with hooks outside the box, installation of slings, grounding devices, nameplates,

First-class iron core and winding structure, with the following features and equipment:

One (or two) high-pressure bushings, which are led out from the cover, and the casing has a built-in current limiting fuse Breaker.

One (or two) arresters mounted on the wall of the box with the end close to the high pressure sleeve

The end of the tube is connected by a copper strip. a secondary disconnect switch is placed in the box,

The box wall is equipped with an operating handle, overload reset and signal light. Low pressure casing

At the wall of the box, X2 is equipped with a grounding device, and one end of the single sleeve passes through the high voltage bushing.

Lead out and ground the other end.

Application:

Rural power grids, remote mountainous areas, scattered villages, agricultural production, lighting and power

Electricity can also be used for energy-saving retrofit on-column distribution lines for railways and urban power grids. It can be operated in single-phase or three-phase single-phase as three-phase operation.
