摘要:
在统计分析电气设备实际运行故障情况的基础上，确定温度为计划维修周期的可变依据，提出将温度变量纳入电气设备计划维修周期的制定当中。以设备无故障运行时间为研究对象，分3种情况建立电气设备故障概率分布模型，采用极大似然估计和K-S拟合优度检验方法最终确定电气设备故障概率分布模型；结合多项式曲线拟合方法，确定温度变量与上述模型参数间的关系，建立电气设备故障条件概率分布模型；以可靠度为约束条件，制定电气设备的计划维修周期。以无锡地铁门禁工作站电气设备为例，验证了该方法的可行性。
Abstracts:
Based on the statistical analysis of electrical equipment failures during actual operation, temperature is defined as the variable basis for planned maintenance cycle. Temperature variable is proposed to be included in the formulation of the electrical equipment planned maintenance cycle. Taking the failure-free operating time of the equipment as research object, an electrical equipment failure probability distribution model is constructed in three conditions, which is finally determined by adopting maximum likelihood estimation and K-S goodness-of-fit test method. Combined with the polynomial curve fitting method, the relationship between temperature variables and the parameters of the above model is determined, on this basis, the electrical equipment failure condition probability distribution model is established. With reliability as the constraint condition, the planned maintenance cycle of electrical equipment is formulated. Taking Wuxi metro access control workstation electrical equipment as an example, the feasibility of the method is verified.
