Outdoor Power Transformer 10 Mva 33 to 6.6 Kv

The outdoor power transformer 10 mva 33 to 6.6 kv with a capacity of 10 mva and a voltage range of 33 to 6.6 kv,  is a type of outdoor power transformer. Its rated voltage is 10 mva, with the high voltage side at 33 kv and the low voltage side at 6.6 kv. It is a mainstream medium sized transformer equipment for industrial and mining enterprises as well as industrial parks, and fully complies with IEC standards. Outdoor power transformer 10 mva 33 to 6.6 kv mainly concludes windings, iron core and insulating oil three parts.

The windings are the electrical part of the transformer. It is generally made by winding insulated flat copper wire or round copper wire on a winding mold. The windings are installed on the iron core column of the outdoor power transformer 10 mva 33 to 6.6 kv. The low voltage windings are on the inner layer, and the high-voltage windings are installed outside the low voltage winding. Between the low voltage windings and the iron core, and between the high voltage windings and the low voltage windings, insulating materials are used to make sleeves to separate them, so as to achieve insulation.

The iron core is the main magnetic path part of the outdoor power transformer 10 mva 33 to 6.6 kv. It is usually made by stacking silicon containing hot rolled or cold rolled silicon steel sheets with a thickness of 0.35 or 0.5 mm and coated with insulating paint. The iron core is divided into two parts: the iron core column and the yoke. The iron core column is equipped with the winding, and the yoke is used to close the magnetic circuit. The basic forms of the iron core structure include the heart type and the shell type.

What are the various installation forms of outdoor power transformer 10 mva 33 to 6.6 kv?

In power engineering, the installation of outdoor transformers mainly consists of two forms: pole mounted installation and ground mounted installation. No matter which method is adopted, safety always comes first. At the most prominent place around the transformer, a conspicuous warning sign must be hung to remind passers-by not to approach.

For outdoor power transformer 10 mva 33 to 6.6 kv installed on the ground, a protective fence with a height of no less than 1.7 meters must be added around it, and there should be sufficient safe operation space between the fence and the transformer platform.

For the installation on poles or towers, it is required that all high and low voltage leads must use insulated conductors and the low voltage part can also use bare busbars. All the iron parts used must be galvanized to prevent rust and corrosion.

If the installation is done on the ground, the base height is usually set at around 500mm. This base is typically constructed using bricks or poured concrete, and then the surface is smoothed with 1:2 cement mortar. Flat steel or channel steel needs to be laid on the surface to serve as the running track for the transformer.

During installation, it is essential to ensure that the track is level and that the track gauge perfectly matches the wheel gauge of the transformer to ensure stable operation.
