本设备共 14 个失效模式(FM),其中 0 个为高风险(S≥8 或 O≥8)。 主导风险来自「IGBT 功率模块失效」(S=7, O=3, AP=低)。 主要失效机理:IGBT 模块在功率循环热应力下键合线(wire bond)疲劳断裂与栅氧击穿(Coffin-Manson 热疲劳),导致短路/开路, 铝电解电容在纹波电流热应力下电解液蒸发干涸,等效串联电阻 ESR 上升、容值衰减(Arrhenius 温度模型),滤波劣化, 冷却风扇轴承磨损卡滞或电机绕组开路,强制风冷流量不足致 IGBT 结温上升。 RCM 维修决策以 PM 为主(CBM 5 / PM 9 / RTF 0)。 当前无高风险 FM,维持既定 ITPM 周期即可。This equipment has 14 failure modes (FM), of which 0 are high-risk (S≥8 or O≥8). The dominant risk is 'IGBT 功率模块失效' (S=7, O=3, AP=低). Main failure mechanisms: IGBT 模块在功率循环热应力下键合线(wire bond)疲劳断裂与栅氧击穿(Coffin-Manson 热疲劳),导致短路/开路, 铝电解电容在纹波电流热应力下电解液蒸发干涸,等效串联电阻 ESR 上升、容值衰减(Arrhenius 温度模型),滤波劣化, 冷却风扇轴承磨损卡滞或电机绕组开路,强制风冷流量不足致 IGBT 结温上升. RCM maintenance decisions are dominated by PM (CBM 5 / PM 9 / RTF 0). No high-risk FMs at present; maintain the established ITPM interval.

4.1 处方与成本权衡4.1 Prescription & Cost Trade-off

成本取自 crq 参数(cp=检验成本,cf=失效纠正成本),预期风险削减为不执行该工单的年度失效概率上限近似。当前 crq 未标实测来源,统一标注 prior-template(非装置实测成本);实测数据经 ingest_measured 审批并入后转 posterior,削减值将升级为风险成本率精算(goal_planning._cost_rate_at)。Costs are drawn from crq parameters (cp = inspection cost, cf = failure correction cost); expected risk reduction approximates the upper bound of annual failure probability if the work order is not executed. Current crq has no measured source, uniformly tagged prior-template (not as-found plant cost); once measured data is approved and ingested via ingest_measured it switches to posterior, and the reduction upgrades to a risk-cost-rate actuarial value (goal_planning._cost_rate_at).
