Dry-type transformer
- Product Description
-
Structural Composition
Core: Made of stacked silicon steel sheets, coated with insulating varnish on the surface to reduce hysteresis and eddy current losses. Usually designed in "E" or "C" shapes, depending on the transformer's capacity and voltage level.
Windings: Made of copper or aluminum wire, divided into high-voltage and low-voltage windings. They transfer magnetic flux through the core to achieve voltage transformation. Common winding forms include winding, epoxy resin filled with quartz sand casting, and glass fiber reinforced epoxy resin casting.
Insulating Materials: Including insulating varnish, insulating paper, insulating tubes, etc., used to wrap the windings and core to improve insulation performance.
Temperature Control System: Equipped with temperature sensors and radiators, it can monitor the operating temperature of the transformer and automatically alarm or trip when the temperature is too high to prevent transformer overheating damage.
Working Principle
Based on the law of electromagnetic induction, when the transformer is powered on, alternating current generates a changing magnetic field in the high-voltage winding. This magnetic field induces an electromotive force in the core, forming a closed magnetic flux. The magnetic flux induces an electromotive force in the low-voltage winding, thereby achieving voltage transformation.
Cooling Methods
Natural Air Cooling (AN): The transformer can operate continuously at rated capacity for a long time.
Forced Air Cooling (AF): By installing cooling fans, the transformer's output capacity can be increased, generally by 50%, suitable for intermittent overload operation or emergency overload operation.
Product Advantages
Safety and Fire Prevention: Does not use insulating oil, eliminating the risk of oil combustion and explosion, and can operate directly at the load center.
Easy Maintenance: No oil impregnation, no need to replace insulating oil or perform other maintenance work, reducing maintenance costs.
Excellent Performance: High mechanical strength, strong short-circuit resistance, low partial discharge, good thermal stability, high reliability, and long service life.
Energy Saving and Low Noise: Low loss, low noise, and significant energy-saving effects.Strong Adaptability: Good moisture resistance, able to adapt to high humidity and other harsh environments, equipped with comprehensive temperature detection and protection systems.
Compact and Lightweight: Occupies less space and has low installation costs.Application Fields
Widely used in important buildings with high fire protection requirements and dense personnel, such as high-rise buildings, underground buildings, airports, theaters, subways, etc., as well as large industrial and mining areas requiring fire and explosion protection, such as self-use transformers in thermal power plants, hydropower plants, and nuclear power plants.
