Baoding oil-immersed transformer is important electric power equipment, guarantee the safe operation of the oil-immersed transformer is very necessary, but in baoding oil-immersed transformer fault occurs in the operation of the problem is also inevitable, therefore, how to deal with the problem of transformer fault, reduce the damage, much attention has been paid to also become the primary problem of relationship between users. Next, the supplier of oil-immersed transformer will analyze the common faults of oil-immersed transformer.
The common faults in the operation are winding, casing and tapping switch and failure of iron core, fuel tank and other accessories. The details are as follows:
1. Winding failure.
The fault of oil-immersed internal winding mainly includes interturn short circuit, winding grounding, interphase short circuit, broken wire and joint welding.
Second, the core
The fault of the core is mainly caused by the insulation damage of the core screw or the clamping screw of the core.
3. Casing failure.
The deposit of oil-immersed transformer bushing is caused by pollution flashover in fog or light rain, which makes the transformer high voltage side single phase grounding or interphase short circuit.
4. Tapping switch.
The common faults of the transformer tap switch are the contact or position of the tapping switch, the contact surface of the contact surface is melted and burned, and the contact discharge of the interphase contact is discharged.
5. External overvoltage of the voltage device.
Running transformer is struck by lightning, because of lightning potential is very high, will cause variable voltage external overvoltage, when some parameters change of the power system, because of electromagnetic oscillation, will cause the transformer internal overvoltage, these two types of overvoltage caused by the damage of transformer windings are mostly the main insulation breakdown, the transformer fault.
Vi. Leakage oil
Transformer oil leakage serious or continuous from lesions spillover, lead to the oil level of transformer oil is too low, the casing and tap-changer lead exposure to air, low insulation level will be greatly reduced, so easy cause breakdown discharge. Once the transformer is leaking oil problem, it is necessary to stop the transformer immediately, find the cause and make up the leakage and refueling. In general, the cause of oil leakage of transformer is the weld crack or seal failure, and the operation is affected by the vibration of external forces.
