Dangers of Using Rusty Transformer Silicon Steel Sheets!
When introducing the raw materials used in our transformers, we emphasize that STB selects brand-new silicon steel sheets as the core material. If non-new silicon steel sheets are used, the probability of rust formation increases significantly, leading to the following potential safety hazards during operation:
- Inter-sheet short circuits: Rust between sheets can create short circuits, increasing core losses and reducing transformer efficiency.
- Core overheating: Short circuits caused by rust can lead to excessive core heating. Prolonged overheating compromises the insulation performance of the transformer and shortens its service life.
- Reduced magnetic permeability: Rust on silicon steel sheets impairs the magnetic permeability of the transformer, preventing the magnetic flux from reaching expected levels and affecting normal operation.
- Increased energy losses: Transformer losses include hysteresis loss and eddy current loss. Rust can exacerbate both, raising induced currents in the core and resulting in additional heat generation and energy waste.
As shown, rusty transformer silicon steel sheets represent a serious fault. To prevent this issue, we recommend:
- Conducting on-site inspections of transformer manufacturers to verify the use of new silicon steel sheet materials.
- Ensuring impregnation treatment during transformer manufacturing to extend the lifespan of silicon steel sheets and prevent rust.
- Implementing proper maintenance and care during operation to ensure preventive measures are in place.
