Core Summary:
The horizontal winding machine is a classic piece of equipment for transformer coil manufacturing, suitable for most standard power transformers. Its characteristic is that the coil rotates on a horizontal axis, allowing operators to observe and operate from ground level or a platform.
Technical Analysis:
Structural Composition: Modern horizontal winding machines (such as the DRX series) mainly consist of a headstock, bed, tailstock, and control system. To accommodate large-tonnage coils (e.g., over 10 tons), the equipment requires deep foundation pits and anchor bolt fixation to prevent resonance.
Application Scope:
Coil Shapes: Supports circular, elliptical, and rectangular shapes (elliptical/rectangular typically require special formwork).
Conductor Types: Suitable for CTC (continuously transposed cable), rectangular copper wire, and foil windings.
Reference Technical Parameters:
Load Capacity: Ranges from small 1-ton equipment to large units over 10 tons.
Speed Range: Typically uses AC variable frequency motors with adjustable speeds from 0-240 r/min. High-torque equipment operates at lower speeds (e.g., 0-15 r/min) to ensure smooth start/stop.
Advantages and Disadvantages:
Advantages: Intuitive operation, easy observation of turn arrangement, suitable for precision winding of high-voltage coils.
Limitations: When the coil's radial thickness is extremely large, gravity can cause the coil to sag and deform. Also, large-diameter coils are difficult to hoist.
