Description

An energy-saving dry-type transformer and its application method

technical field

The invention relates to the field of transformers, in particular to an energy-saving dry-type transformer and a use method thereof.

Background technique

The dry-type transformer is mainly composed of an iron core composed of silicon steel sheets and a coil casted by epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and restrained by pads, and fasteners for overlapping parts Both have anti-loose performance. Widely used in local lighting, high-rise buildings, airports, wharf CNC machinery and equipment and other places. At present, the pace of construction of urban and rural power grids is accelerating, and my country's power generation and consumption are increasing day by day.

Transformers can be divided into outdoor and indoor types according to installation conditions. Traditional dry-type transformers are generally used for indoor installation because they do not have waterproof effects. A corresponding protective shell is added to the transformer to form a waterproof dry-type transformer together with the dry-type transformer, which is used to protect the internal high-voltage coil. When working, rainwater easily enters the interior through the heat sink of the outer shell, so that the rainwater easily erodes the high-voltage coil. After rainwater erosion, the iron core on the surface of the high-voltage coil will rust, which will cause short circuit, no-load loss and The problem of no-load current increase occurs, and at the same time, the insulation layer on the outer surface of the pull plate will be lost, resulting in short-circuit loss of the dry-type transformer.

Therefore, we improve this and propose an energy-saving dry-type transformer.
