Treatment Methods For Scratches On Constant Voltage Transformers

If minor scratches are found on the surface or insulation layer during operation, the extent of the damage should be immediately determined, and the surrounding structure and insulation medium should be carefully inspected. If such scratches are left untreated, they can easily cause localized partial discharge or insulation degradation, potentially affecting the overall performance of 3 phase constant voltage transformer.

The following procedures can be followed for discovered scratches:

Inspect the functional properties of the component at the damaged location. If necessary, stop power supply to the relevant circuits. Use professional testing instruments to assess the insulation layer thickness and conductor exposure status. For scratches in the insulation layer, repair with suitable insulating tape or insulating material. Adjust the repair layer thickness according to the damage depth and mark the location for future use. The maintenance site should also verify the tightness and mechanical stress of surrounding connecting components to prevent further damage during subsequent operation.

For deeper or larger damage, a shutdown and disassembly inspection can be arranged. Based on the site conditions, decide whether to replace the affected insulation components or take reinforcement measures. After repair, conduct a local withstand voltage test and operational observation to ensure there are no abnormal electrical phenomena before resuming normal operation. Scientific evaluation and standardized processing procedures help maintain the overall performance stability and safe operation of constant voltage transformer for home.
