What should be noted when assembling the transformer winding? (2)

In transformer manufacturing, the winding assembly process is of crucial importance and directly relates to the performance and operational reliability of the transformer. The following focuses on the key points in the winding assembly process.

1. Symmetry and alignment in the height direction

(1) Height difference and reasons of high-voltage and low-voltage windings:

Winding assembly needs to maintain symmetry in the height direction. Due to the high voltage to ground, the high-voltage winding has a large insulation distance and is generally shorter than the low-voltage winding. Moreover, due to manufacturing tolerances, there are tolerances in the heights of high-voltage and low-voltage windings. These factors need to be considered during assembly.

(2) Importance of geometric center alignment:

Ensuring the alignment of the geometric centers of high-voltage and low-voltage windings is of crucial importance. Misalignment will increase the axial electromagnetic force, leading to a further expansion of the height difference, affecting the overall structural stability and performance of the transformer. For example, it may cause winding loosening and deformation, affect electromagnetic coupling, increase losses, and even cause local overheating.

2. Core protection and optimization of assembly method during the assembly process

(1) Protective measures for the upper end of the core:

When assembling windings on the iron core bound with glass adhesive tape, the upper end of the core column should be clamped and tied firmly in advance with clamps and straps to prevent the iron core sheets from toppling and causing the adhesive tape to crack, thus destroying the integrity and insulation performance of the core and affecting the operation of the transformer.

(2) Advantages of overall combined assembly:

For winding assembly, it is advisable to assemble the windings together first and then assemble them as a whole on the iron core column. This can speed up the assembly speed of the transformer body, improve production efficiency, and at the same time reduce the possibility of moisture absorption and ensure insulation performance and operational reliability.

Подводя итог

In short, during the transformer winding assembly process, points such as winding direction, misalignment control, height alignment, iron core protection, and assembly method all need to be strictly controlled. Operators must have a high sense of responsibility and professional skills to ensure that each link is accurate and error-free to guarantee the quality and performance of the transformer and provide strong support for the stable operation of the power system. Any negligence may cause serious problems and must be taken seriously.
