摘要
为准确评估1 000 k V等电位户外固定式在线验电器的寿命,以铝电解电容、半导体元件、电阻以及LED四类组成元件的寿命函数为基础,使用Palisade Risk软件对户外固定式在线验电器系统的预期寿命进行蒙特卡洛模拟,得到的模拟结果显示1 000 k V户外等电位固定式验电器平均寿命为60 000 h左右,失效分布为指数分布。
To accurately evaluate the lifetime of 1 000 kV outdoor equipotential ifxed online charge detector, based on the lifetime func-tions of four kinds of constituent components including aluminum electrolytic capacitor, semiconductor component, resistance and light-emitting diode （LED）, this paper used the software Palisade Risk to do a Monte-Carlo simulation on the overall detector system’s lifespan. The simulation result shows that the 1 000 kV outdoor equipotential ifxed charge detector has a mean time to failure of 60 000 h, and the failure rate distribution is an exponential distribution.
