Under some conditions , short - circuit test on balanced transformers can be performed by means of 1 . 5 phase supply . it is proved to be equivalent to the short - circuit fault during their operation . the test results comply with gb1094 . 5 - 1985 建立一定的试验条件,在1 . 5相电源双臂预先短路情况下进行短路试验,使短路试验能够同时满足实际运行中发生短路时的短路电流有效值和短路电流峰值的要求,并进行试验验证。
In this study , the design procedures for mitigating radiation effects mechanisms have been implemented in a gate array design , we have obtained samples of integrated circuits test structures manufactured by wuxi csmc - hj using their 0 . 6 - m cmos process 在研究中,我们将降低辐射效应的设计方法应用到门阵列设计中,获得了华晶上华半导体有限公司采用0 . 6 m的cmos工艺生产的集成电路样片,具有100krad ( si )的抗总剂量辐射能力。
Impedance - matching balanced traction transformers ( balanced transformers in this paper for short ) are step - down transformers , they transfer symmetrical three phase voltage in primary side to perpendicular two phase voltage in secondary side . they are different from any other transformers , so their short - circuit current analysis and short - circuit test method must be taken into special account 阻抗匹配平衡牵引变压器(本文中简称平衡变压器)是一种将一次侧三相对称电压变换为二次侧二相垂直电压的降压变压器,它不同于已有的任何一种变压器,短路电流的分析计算和短路试验必须予以重新研究。
Abstract : according to the requirement of mineral processing for particle size of grinding and based on closed - circuit test to second - stage grinding and production shakedown , the possibility and effect of which two - stage classification technology is used for transformation of the second - stage grinding flowsheet were discussed through calculation and analysis 文摘:考虑到选矿工艺对磨矿产品的粒度要求,根据第2段磨矿机局部闭路生产调试的结果,通过计算和分析,探讨用两段分级技术改造第2段磨矿流程的可能性及其效果。
