In the power industry, the safety of the transformer has always been a subject of concern. But in the operation of the transformer in practical inevitably happen one way or the other fault, therefore, how to reduce the transformer faults occur, ensure safe operation of power system become the chief concern of the manufacturer. So, what are the common failure problems in the operation of the baoding oil immersed transformer? The following is with the baoding oil immersed transformer supplier to understand.
Baoding oil-immersed transformer supplier, now in power system, the common faults in the operation of the transformer in a winding, casing and tap-changer and failure of iron core, fuel tanks and other accessories. The details are as follows:
1. Winding fault
There are interturn short circuit, winding grounding, interphase short circuit, broken wire and joint open welding, etc.
2, 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
Transformer casing fouling, causing pollution flashover in fog or light rain, make transformer high voltage side single phase grounding or interphase short circuit.
4. Tapping switch
The common faults include the contact or position of the tapping switch, the surface melting and burning of the contact surface, and the discharge of the contact discharge.
5. Overvoltage
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.
6. Leakage oil
The oil level of the transformer oil is too low, so that the casing leads and tapping switch are exposed to the air, the insulation level will be greatly reduced, and therefore the breakdown discharge will be easily caused. The transformer will be immediately stop using for leakproof and refueling, the causes of transformer oil leakage are welding crack or seal failure, in the operation of the shock force collision tank of serious corrosion and damage.
