Dry Type Transformer

Overview of Dry Type Transformer

Dry-type transformers are a specific kind of transformer where the windings and the core are not encased in insulating oil but are open to the air. Dry-type transformers are typically employed in high-rise and local lighting docks, airports, buildings, CNC mechanical equipment, and other locations. Compared to traditional oil-immersed transformers, dry-type transformers offer advantages such as lower loss, quiet, simple design, and easy maintenance.

The Characteristics of Dry-type Transformers

• Safe and reliable: Dry-type transformers have high technical capabilities, high mechanical strength, intense short-circuit resistance, slight partial discharge, good thermal stability, and high reliability, thus ensuring safe and reliable operation.
• Environmental Protection and Energy Conservation: Dry-type transformers use advanced insulation materials and process technology, which have low losses, low noise, and apparent energy-saving effects. They do not use oil and will not produce oil waste or pollute soil and water sources, making them a more green choice.
• Easy maintenance: As no oil is used, dry-type transformers do not require oil replacement or insulation system maintenance, resulting in a low maintenance workload and long service life.
• Fire and explosion prevention: Dry-type transformers can operate directly at the load center, and the loaded core can operate safely, fireproof, and with zero pollution simultaneously.
• Good heat dissipation performance: The dry-type transformer adopts forced air cooling technology, which has strong overload working ability and can improve the transformer capacity for operation.
• Small size and lightweight: Dry-type transformers are small and light, have a small footprint, and have a low installation cost.
• Intelligentization: Dry-type transformers can be equipped with a comprehensive temperature detection and protection system, adopting an intelligent signal temperature control system that can automatically detect and display the working temperature of each three-phase winding and have functions such as alarm and trip settings

FAQ

What is a dry-type transformer?

Re: A dry-type transformer is a special type of transformer where the iron core and winding are not immersed in insulating liquids, but are completely exposed to air. This type of transformer is usually used in some special environments, such as flammable, explosive, or humid environments.

What are the advantages of dry-type transformers?

Re: Dry type transformers have many advantages, including good fire resistance, safe and reliable operation, and convenient maintenance. In addition, due to the lack of insulation oil, dry-type transformers will not have oil leakage problems and will not pollute the environment.

What situations are dry type transformers suitable for?

Re: Dry type transformers are suitable for many different occasions, such as residential, commercial, and industrial fields. Due to its excellent fire resistance, it is particularly suitable for use in flammable and explosive environments. In addition, dry-type transformers are also suitable for environments that require oil-free operation.

What are the common faults of dry-type transformers?

Re: Common faults in dry-type transformers include open circuit, short circuit or grounding faults in the winding, and multiple grounding faults in the iron core. In addition, there may be issues such as transformer overheating and abnormal sound. To prevent these malfunctions from occurring, regular maintenance and inspections are necessary.

How to maintain dry-type transformers?

Re: Regular inspections are required to maintain dry-type transformers, including checking for any abnormalities in appearance, checking if all connecting parts are tight, and measuring insulation resistance. In addition, the surrounding environment of the transformer should be kept clean to prevent dust and debris from entering the interior of the transformer. If any problems are found, they should be dealt with promptly to ensure the normal operation of the transformer.
