FAQ

1. Insulation aging: Insulating materials in transformers will age over time, reducing their insulating properties and making them prone to insulation breakdown faults.
2. Winding short circuit: A short circuit between the transformer windings can lead to an insulation breakdown fault.
3. External factors: External factors such as lightning strikes and overvoltage can also easily cause insulation breakdown faults.

1. Short circuit fault: A short circuit fault between the transformer windings or with external equipment can lead to a tripping fault.
2. Overload fault: When the transformer carries an excessive load, it can easily trigger the overload protection device, leading to a tripping fault.
3. Operational error: Tripping faults caused by operator errors are also quite common.

1. Insulation aging: The aging of transformer insulating parts can lead to insulation failure, resulting in oil leakage faults.
2. Condensation retention: Due to significant temperature changes during transformer operation, condensation is likely to form. If not removed in time, it can cause internal oil leakage.
3. Manufacturing quality issues: Some transformers have substandard manufacturing quality, leading to oil leakage faults.

Hardware fracture is one of the typical failure phenomena of overhead line hardware. Fractures usually occur near the connection points or key parts of the hardware. Fractures may be caused by poor hardware quality, fatigue, overload, or material defects.

Hardware corrosion refers to the phenomenon of surface corrosion and internal material strength reduction of hardware during its use. Hardware corrosion makes the hardware more fragile when subjected to force, making it prone to fractures and deformation.

Hardware loosening is one of the common failure phenomena of overhead line hardware. Hardware loosening may be caused by improper installation, external vibration, or thread damage. The loosening of hardware affects its fixing effect, thereby affecting the safe operation of the line.

Hardware oxidation refers to the oxidation reaction that occurs on the surface and inside of hardware when it is exposed to the atmosphere for a long time. Hardware oxidation can lead to a decline in mechanical and electrical properties of the hardware, leading to faults.
