s11 How to deal with transformer accident fault

s11 Transformer accident disposal Standard line for s11 transformer trip disposal: When s11 transformer trips, it shall stop inspection according to the on-site regulations, analyze the maintenance operation status and the external phenomenon at the time of the accident, identify the accident status and stop disposal. Gas maintenance and differential maintenance trip at the same time, before the cause is found out and the fault is eliminated, the power shall not be sent to s11 transformer differential maintenance trip at the same time, the main transformer shall be immediately inspected externally. At the same time, inform the working area, experiment, maintenance, relay personnel rushed to the scene, stop the inspection of the primary and secondary circuits of the s11 transformer, stop the oil and gas properties of the s11 transformer, and through the DC resistance, insulation and other experiments, the reason is found out after disposal.

When it is proved that there is no problem with the s11 transformer and its maintenance control loop, the s11 transformer can be stopped once. When the system is in urgent need, there is no abnormality after the external inspection and insulation test of the main transformer, and the test can be sent once after the guidance of the supervisor or the approval of the chief engineer. When the gas maintenance action of s11 transformer trips, As long as the exact evidence is found that the gas maintenance is misoperated or there is no problem inside the s11 transformer, the test can be sent.

In case of tripping of s11 transformer overcurrent maintenance action, comprehensive inspection and analysis should be stopped for s11 transformer and its load status and distribution line maintenance action status. If it is determined to be a traversal fault and a step trip is formed, the s11 transformer will stop power transmission after the fault line switch is immediately disconnected without inspection, and the non-fault line will be matched one by one, and then the working area will be notified for experimental inspection.
