Research on Reliability Optimization of Maintenance Cycle for Power Distribution Equipment Based on Fixed Repair Theory
For the traditional power distribution equipment malfunction maintenance problems of labor intensity,high maintenance cost and accident shutdown affect output,this paper studies the optimization strategy of power distribution equipment maintenance under the theory of power distribution equipment cycle maintenance,establish the distribution equipment maintenance countermeasure model in different fault modes,and build the distribution equipment fault tree model,optimize the distribution equipment maintenance cycle based on the fault model tree and the reliability theory.After on-site application in a distribution network company,it was shown that the optimized maintenance cycle of distribution equipment effectively improved the operation and maintenance efficiency and maintenance quality of 110 kV distribution equipment,reduced the maintenance cost,and saved the inspection cost of about 150 000 yuan per year,and achieved satisfactory application results.
