Features of Dry Type Transformer Split Transformer with Multiple Windings

Robust Dry Construction: Adopting a dry design with high insulation level and dust-proof and moisture-proof ability.

Maintenance-free and fire-safe: Without oil, so there is no risk of fire in oil immersed transformers, and there is no need for routine maintenance and oil replacement operations.

Split Winding Capacity Equivalence: The total capacity of each split winding in a dry-type split transformer is the rated capacity of the split transformer. Usually, the low-voltage winding is divided into two or three branches as a split winding, with the line end marked with lowercase letters and numbers. The non-split high-voltage winding is composed of two parallel branches, with the line end markings unchanged. The total capacity of each split winding is the rated capacity of the split transformer.

Applications of Dry Type Transformer Split Transformer with Multiple Windings

Pearl Electric provides reliable and stable dry-type split transformers in multiple fields. The following are some common application scenarios:

Photovoltaic power generation field: In photovoltaic power plants, dry-type split transformers are often used to convert the direct current generated by solar panels into alternating current, which is then integrated into the grid through a step-up transformer. This type of transformer can meet the needs of large-scale photovoltaic power generation; improve the stability and reliability of the power system.

In the field of hydrogen production: Dry split transformers have also been widely used in hydrogen production and storage systems. Dry split transformers are used to convert water electrolysis into hydrogen and store it in underground gas storage facilities. This type of transformer can improve electrolysis efficiency, control the direction and speed of electrolysis reactions, and ensure the safe operation of the equipment.

Power system distribution: In the distribution system, dry-type split transformers are usually used as main transformers to convert high voltage into low voltage suitable for industrial, commercial, residential and other places. This type of transformer can meet the needs of different voltage levels, improve power quality, and ensure the stable operation of the power system.

Special industrial applications: In certain special industrial applications, such as metallurgy, mining, petrochemicals, etc., dry-type split transformers also play an important role. In these fields, dry-type split transformers can meet special working environments and equipment requirements, providing reliable power supply and protection.
