| Our country power plant electrical equipment maintenance carries out continuously take the time as the foundation regular preventative maintenance system, but enhances, the single plane capacity along with the power plant electrical equipment voltage rank increases, as well as the movement fixed number of years change, again continues to use take the fixed time reveals as the basis preventative maintenance system is more and more inappropriate. Therefore, develops unceasingly take the on-line examination as the fundamental mode each kind of electrical equipment state of insulation monitor technology, developed unceasingly from the regular plan maintenance to the condition maintenance has also become the power equipment maintenance system reform inevitable trend.The realization condition maintenance, must hold three key links: Equipment information grasping;Synthesis condition diagnosis;Maintenance management. The present paper through to equipment the and so on generator, transformer, circuit breaker, isolator, line insulator insulation breakdown appraised that, has analyzed each kind of equipment implementation condition examination technical plan, and briefed my factory practical application situation.The equipment condition appraisal if also merely is qualitative "good" or "is bad", cannot carry on the condition maintenance, for this, we has established "the hundred-mark system" the condition appraisal system, then completes the synthesis equipment history information, the current condition, the environment data, the system demand and so on many factors based on the fail-safe analysis maintenance plan optimization formulation.In the victory power plant existing equipment management system management system foundation, has completed the condition maintenance management system management system development, to optimized the maintenance plan flow to carry on the research summary, and has carried on the analysis explanation to my factory improvement maintenance several instances. |
