life index
Examples
- The endurance function of the insulation field is widely concerned in the power system . according to the equality between the two dimensional weibull distribution and the law of electrical aging , after the method for estimation of the voltage endurance coefficient is presented by the maximum likelihood estimation and the minimum square estimation of the two dimensional weibull distribution parameters , on the basis of the analysis of the test disadvantages under invariable voltage , the method of obtaining the voltage endurance coefficient under the intension increased by degrees is considered
电气绝缘电老化性能是电力系统普遍关注的问题,由于二元weibull分布与电老化定律在评价绝缘老化特性上存在等价性,本文首先介绍了二元weibull分布参数采用极大似然法和最小二乘法估计获得电压寿命指数的方法,同时在分析其在恒定电压下试验容易出现,由于电压选择不当导致试验时间过长现象的基础上,讨论了利用场强递增方式确定电压寿命指数的方法。
