简介：吐哈油田甲醇厂采用了两台功率为3300kW的正压通风型交流高压无刷励磁同步电动机、配套静态励磁装置(WLK-02H型),运行以来,同步电动机励磁装置曾出现故障,本文摘取其中较为典型的几例故障进行分析。

简介：针对采用输出电容电流和电感电流作为主反馈变量的两种多闭环控制策略的特点进行了详细的研究，提出了对这两种运算的谐波差异和瞬态性能的估计。通过向输出电压调节环巾引入交流PI调节器完全消除了稳态误差，并且有效地运用电容电流反馈，得到了令人满意的稳态和瞬态特性。

简介：译者说明：电——气压力调节器通常称为EP阀，也有的生产厂家称其为电——气比例阀或电——气比例压力阀。这种装置一般用在自动化程度比较高，电子和空气联合远程摇控的大型设备上。湘潭电机股份有限公司生产的Q6W-2型城市轻轨车上安装的模拟制动机就采用了这种EP阀。它的工作原理是什么、有哪些结构特点、如何操作?下面就以美国Parker公司制造的P3P—R系列集成电子控制的电气压力调节器为实例，对以上问题加以综合描述。

简介：断路器的发展主要体现在断路技术的发展和新绝缘材料的应用上。在20世纪50-70年代，应用较多的是油断路器和空气断路器。70年代后，主要采用SF6断路器，该断路器绝缘性能好，结构相对简单，因而得到了广泛推广与应用。在过去的几十年里，随着材料科学的进步，SFS断路器的可靠性有

简介：对特定的性能参数（如效率）进行优化时，其他参数总是要作一些调整。本文目的是对决定电动机可靠性的各种性能参数和要素进行比较。除了电动机耐用性外，还考虑了对电动机寿命的影响。本文仅对根据1992年能源法生产的三相笼型感应电动机与普通电动机进行比较。
