dry type transformer Buying Guide
1. What is a dry type transformer?
There are two kinds of transformers we commonly use, dry type transformers and oil-immersed transformers.
Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Simply put, dry-type transformers are transformers whose cores and windings are not impregnated in insulating oil.
Dry-type transformer cooling method is divided into natural air cooling (AN) and forced air cooling (AF).
With natural air cooling, the transformer can operate continuously at rated capacity for a long period of time. With forced air cooling, the transformer output capacity can be increased by up to 50%.
It is suitable for intermittent overload operation, or emergency accident overload operation; because of the load loss and impedance voltage increase during overload, it is in a non-economic operation state, so it should not be in long time continuous overload operation.
2. How dry type transformers work?
As with other transformers, following the physical principles of electrical and magnetic coupling required for the use of voltage technology, when current flows through the wire, it generates a changing magnetic field or “magnetic” around it. The magnetic field fluctuates around the wire and it generates a current in the wire.
Therefore, the second wire and the first wire will have fluctuating magnetic fields placed next to each other, and the current is induced to flow in the second wire. Therefore, the electricity is passed through the two wires from the first second wire, without actually touching each other.
A dry-type transformer is actually an electrical appliance that uses the principle of electromagnetic induction to transfer electrical energy or transmit signals from one circuit to another is an important element for electrical energy transfer or as a signal transmission.
It is widely used in local lighting, high-rise buildings, airports, terminals, CNC machinery and equipment, etc. Simply put, dry-type transformers are transformers whose cores and windings are not impregnated in insulating oil.
Dry-type transformers are mainly divided into three forms: open type, closed type and cast type.
3.How dry type transformers are cooled
Dry-type transformers are cooled using a variety of methods, depending on the type of transformer. Air-cooled transformers use fans to circulate air around the transformer, while water-cooled transformers use water jackets or cooling towers. Oil-cooled transformers use either oil-filled cooling coils or oil-filled radiators.
You can also install a separate fan heating device for the dry-type transformer, such as an air conditioner.
4.Dry type transformer applications
Dry-type transformers are used in a variety of applications, from small electronic devices to large industrial plants. Their unique design makes them well-suited for use in environments where space is limited or where there is a risk of fire or explosion.
Dry-type transformers are also used in power generation and distribution, providing a safe and efficient way to transfer electricity from one place to another.
Dry-type transformers are an important part of the electrical grid, and their use is growing in popularity due to their many advantages.
5.Dry-type transformer construction
Dry-type transformers are built with a few key components that work together to provide power transformation. The core is made of stacked laminations of silicon steel that create a thin, strong magnetic circuit. The coil is made of insulated copper or aluminum wire that is wound around the core. The frame holds everything together and provides support.
There are two types of dry-typetransformers: air-cooled and liquid-filled. Air-cooled transformers have fans that circulate air around the transformer to keep it cool. Liquid-filled transformers are filled with a dielectric fluid that helps to dissipate heat.
Dry-type transformers are more efficient than oil-filled transformers and can be used in a variety of applications, including industrial, commercial, and utility.
6.The benefits of dry type transformers
Dry-type transformers are becoming increasingly popular in a variety of settings. That’s because they offer a number of advantages over their oil-filled counterparts.
One of the biggest benefits of dry-type transformers is that they are much less likely to catch fire. That’s because there is no oil inside them to ignite. If a dry-type transformer does catch fire, it will usually be contained to the transformer itself.
Dry-type transformers are also more environmentally friendly. That’s because they don’t use oil, which can be a pollutant. They also don’t require the same level of maintenance as oil-filled transformers.
Finally, dry-type transformers are typically more efficient than oil-filled transformers. That means they waste less energy and can help to lower your energy bills.
If you’re considering a transformer for your home or business, a dry-type transformer is definitely worth considering.
7.The difference between dry type and oil-filled transformers
Dry-type transformers are often used in residential and industrial applications because they are more efficient and have a longer lifespan than oil-filled transformers. But how do they work?
Dry-type transformers use air as the insulating medium, whereas oil-filled transformers use oil. The advantage of using air as the insulating medium is that it is a better conductor of heat, which means that the transformer can operate at a higher temperature without being damaged.
Another advantage of dry-type transformers is that they are less likely to catch fire than oil-filled transformers. This is because the oil in the transformer can act as a fuel source for a fire, whereas air is not flammable.
So, if you’re looking for a more efficient and longer lasting transformer, a dry-type transformer is the way to go.
8. Dry type transformer price
Dry-type transformers are usually cheaper than oil-immersed transformers.
The price of dry-type transformers of different powers is quite different, and there are also price differences in brands and materials.
