What are theReasons and Prevention Methods for Excessive Verticality Deviation of the Core?

Core verticality deviation can lead to damage in the electrical performance and mechanical structure of transformers. Therefore, it is crucial to strictly control the verticality of the core during manufacturing to ensure the normal operation and long lifespan of the transformer. Below are the main causes of core verticality deviation and the corresponding preventive methods.

Main Causes:

●Uneven Stacking Work Surface:

During the core stacking process, if the stacking work surface is not flat enough, it can cause the core column to bend after stacking. Without strict flatness control of each layer during stacking, the entire core's verticality may deviate, affecting its structural stability and electrical performance.

●Insufficient Clamping of the Core:

If the core is not fully clamped before being set upright, it may deform during the lifting and handling process. An unclamped core is prone to deformation due to uneven stress from gravity or handling, leading to verticality deviation.

●Non-Vertical Installation of the Turning Platform:

If the turning legs of the core turning platform are not installed vertically with respect to the stacking work surface, it can cause additional deformation during the setting upright process. The precise installation of the turning platform is crucial for ensuring the core's verticality. Incorrect installation angles can cause the core to shift or bend.

Preventive Methods:

●Adjusting the Level of the Stacking Work Surface:

Before stacking the core, ensure that the level of the stacking work surface has been strictly inspected and adjusted. Use high-precision leveling instruments to measure and adjust the work surface to ensure its flatness, thereby reducing core bending due to uneven surfaces.

●Fully Clamping the Core:

Before setting the core upright, it must be fully clamped to ensure its stability during the process. Additionally, check the turning legs of the turning platform to ensure they are vertical with the stacking work surface and locked in place to prevent position shifts during the upright process.

●Slow and Steady Handling of the Core:

During the handling process, use a crane to perform slow and steady lifting operations. Strictly control the lifting speed to avoid shocks or vibrations to the core, ensuring that the core maintains stable verticality throughout the transportation and installation process.

In summary

By implementing these measures, core verticality deviation can be effectively prevented and controlled, ensuring the reliability and stability of the transformer during operation. Additionally, regularly inspecting and maintaining the precision of the stacking and turning platforms, and ensuring all equipment and operations meet standards, are critical steps in guaranteeing accurate core verticality.
