静变电源培训Maintena,1,培训内容 (Training for Maintenance) 基本介绍 操作说明 故障排除与日常维护,静变电源培训Maintena,2, the safe choice .,400Hz静变电源 ( *MTBF是一个统计数字,其中63%的设备是无故障运行无故障时间后才出现故障。例如100.000小时。而失效则用平均指数等式表示。) Failed systems = F(t) = (1-e(-t / MTBF)*100%. where “t” is the operation time in hours. (失效系统 = F(t) = (1-e(-t / MTBF)*100%. “”的含义是操作小时数。) This equation gives 63 % at t = MTBF. The MTBF figure as such is a theoretical figure which is a bit difficult to relate to in real life. (这个等式当t = MTBF 时为63%。MTBF数字是一个理论化的数字,因此与设备的实际情况有稍许不同。), the safe choice .,
