Dry Type Air-Core Series Reactor
Structure
The Dry Type Air-Core Series Reactor consists of multiple concentric cylindrical windings. These windings are connected in parallel using aluminum or copper conductors and are encapsulated with epoxy resin and fiberglass to form a robust structure. Ventilation channels are provided between the windings to facilitate natural convection for heat dissipation. The surface is coated with a protective layer to resist UV radiation and contamination.
Advantage
◆ Coreless Design
The dry-type air-core reactor does not have an iron core, eliminating the risk of magnetic saturation. This ensures good linearity of inductance, allowing the reactor to maintain stable reactance characteristics over a wide range of currents. It is particularly suitable for applications requiring high linearity.
◆ Oil-Free Structure
The reactor is designed without oil, eliminating the risks of oil leakage and flammability. This design enhances operational safety and environmental friendliness, with no fire hazards.
◆ Excellent Heat Dissipation
The reactor features a multi-layer parallel winding structure with air channels between the enclosures, facilitating natural air convection. This design ensures good heat dissipation and low hotspot temperatures.
◆ High Mechanical Strength
The coil is encapsulated with epoxy resin and fiberglass, forming a robust structure after high-temperature curing. This high mechanical strength enables the reactor to withstand significant short-circuit current impacts.
◆ Low Losses
The winding uses multiple strands of small-section conductors, reducing eddy current losses and stray magnetic losses. This results in low overall losses.
◆ Low Noise
The reactor operates with low noise levels, making it suitable for noise-sensitive applications.
◆ Maintenance-Free
The dry-type air-core reactor requires virtually no maintenance, with a long service life of up to 30 years.
◆ Flexible Installation
The reactor is compact and lightweight, facilitating easy installation. It can be mounted vertically or horizontally and is suitable for both indoor and outdoor environments.
◆ Strong Environmental Adaptability
The outer surface is coated with UV-resistant and anti-aging materials, allowing it to withstand harsh outdoor weather conditions over the long term.
◆ Economic Efficiency
Compared to traditional oil-immersed or iron-core reactors, the dry-type air-core reactor has lower costs and reduced installation and maintenance expenses.
These advantages make the dry-type air-core series reactor widely used in power systems.
