As one of the very excellent power transformer types, dry type transformers are selected and installed in large and small power distribution projects. As one of the transformer manufacturers, ZTelec Group takes stock of the various characteristics and advantages of dry type transformers for you.
What are dry type transformers?
First, let’s understand what is a dry type transformer. Dry type transformers, also known as cast resin transformers, are power transformers with windings encased in epoxy resin. This makes the installation process easier because they are dry and do not require cooling oil. Plus, they do not need to be contained in a fire-proof vault. The layer of epoxy helps protect it against dust and corrosion. Dry-type transformers are used in a wide variety of applications and can be installed indoors or outdoors.
A dry-type transformer has no moving parts, it is a static device that uses environmentally friendly temperature insulation systems. Traditional liquid-type transformers rely on environmentally taxing materials like oil or fire resistant liquid dielectric. “Dry” refers to the fact the system is cooled through natural ventilation as opposed to using oil, silicone or a liquid to cool coils and the electrical core. This type of transformer is defined as “voltage changing,” which means air is cooled instead of cooling liquid. The case the transformer sits inside is ventilated so air can cool coils.
Why are dry type transformers more popular?
Dry type transformers are more popular for the following reasons:
Green environmental protection:
Dry type transformer adopts new technology and new materials, which is in line with modern environmental protection concept.
Compared with traditional oil-immersed transformers, dry type transformers do not contain harmful substances and are conducive to environmental protection.
Strong adaptability:
The dry type transformer is small in size, light in weight and occupies less space. It has low installation cost and is easy to install and use in various environments.
It can adapt to high humidity and other harsh environments, such as solar photovoltaic, wind power and other projects in the field of new energy.
High energy efficiency:
Dry type transformer has the characteristics of low loss and low noise. And the energy saving effect is obvious.
It has good heat dissipation performance, strong overload capacity, and can maintain efficient operation under various load conditions.
Safe and reliable:
Dry type transformer has higher safety performance, which is especially suitable for fire, explosion-proof and other performance requirements of high places.
In flammable and explosive situations, such as factories and workshops, dry type transformers are more widely used because they can effectively reduce the risk of fire and explosion.
High-tech materials and advanced manufacturing processes make dry type transformers outstanding in terms of capacity expansion and stable operation.
Easy maintenance:
The dry type transformer has the advantages of simple structure, small maintenance workload and reduced operation and maintenance cost.
It is also equipped with a perfect temperature detection and protection system, which can automatically detect and display the respective working temperature of the three-phase winding and has functions such as alarm and tripping to further improve the safety and reliability of operation.
Extensive use:
Dry type transformers have been widely used in factories, workshops, commercial buildings, rail transit, new energy fields and residential areas.
With the continuous improvement of the market environment for high efficiency, energy saving and environmental protection requirements, the application prospects of dry type transformers will be broader.
