Cast resin Dry Type 750KVA 13.8KV Excitation Transformer
Product Description
Description about 750KVA Excitation Transformer
Three-phase dry type transformers are a vital component in modern electrical power distribution systems. Their combination of safety, low maintenance, environmental benefits, and reliable performance makes them an attractive option for a wide range of applications. As the demand for efficient and sustainable power solutions continues to grow, three-phase dry type transformers are expected to play an increasingly important role in meeting these needs.
Our Advantages
- Dry-Type Construction: Unlike oil-filled transformers, dry-type transformers use air as the cooling and insulating medium. This eliminates the risk of oil leaks and reduces fire hazards, making them safer for indoor and environmentally sensitive applications.
- Excitation Function: The primary function of an excitation transformer is to supply the excitation voltage required for the rotor windings of synchronous machines. This excitation is essential for controlling the magnetic field in the rotor, which in turn controls the output voltage and power factor of the machine.
- Applications: Dry-type excitation transformers are commonly used in power plants, industrial facilities, and other environments where synchronous generators or motors are employed. They are particularly suitable for indoor installations where oil-filled transformers might pose safety or environmental concerns.
- Cooling System: These transformers rely on natural air circulation or forced air cooling to dissipate heat. This can involve fans or other cooling mechanisms to maintain optimal operating temperatures.
