| | This paper presents a detecting principle of the break in secondary circuit of current transformer in wnich method of initiation of sudden increasing with signal is introduced. The fault break and breaking off switcher are distinguished respectively, so that they are independent each other in the detecting period. Based on it, nigh-speed algorithm is used to detect the inner faults of power transformer which enable the trip impulse to be given out within about 10me. Meanwhile, ... | | 本文提出的CT二次回路断线判别原理,首次引入有符号突变量启动的方法,并将故障、断线、拉闸等分开来,使三者在判别时间上相互独立.在此基础上对故障采用高速的算法,使动作速度仅在10ms左右;同时充分利用断电时的特征量和计算机的记忆存储和计算功能,并采用全波富氏加一阶差分滤波器算法,使断线判断具有很高的准确性,对拉闸采用躲过暂态的方法.上述原理在SWBB-10型变压器保护装置的静态及动态模拟试验中效良好. | | 文摘来源 | | A tentative analysis of the mechanism of mantle circulation flow, continent drifting and earthquake origin is first clearly made, giving a simple mechanics-based explanation of the nature. Then the effects of earthquake mechanism on ground motion and wave propagation are delineated in a simple manner by accounting for the different types of earthquake source, break propagation, as well as the variations of rock property. It is shown on the basis of principles of mechanics that at least two physical pa... | | 首先对地幔对流、大陆漂移和地震起源的机制做了尝试性分析,给出一个简单的力学解释。然后,考虑不同的震源类型,破裂传播以及岩体性质,探讨了震源机制对地面运动和波传播的影响。根据间断(阶跃)波理论阐明了至少应该有两个物理参量才能表征地震烈度,因为在震源处同时有应力阶跃和质点速度阶跃发生。也阐明了断层的破裂速度连同断层面积一起应是第三个重要影响参量,因为它对震源处卸载的时间函数的形式有决定性的影响。由于断层破裂是一个瞬间卸载过程,并引起应力和速度阶跃,而现行惯用的一些概念均未考虑到这一点,所以笔者对工程地震和地震工程中若干概念提出了一些看法,意在引起学术界讨论 | | 文摘来源 | | Introduces that the small diameter presuress anchor is suited for the tunnel support of the larger span room,crosspoint,fault break belt and influced mining.its technique is simple,support is timlier,bearing capacity is bigger.as a reinforce measure for other support,it is a kind of effective reinforce support. | | 小直径预应力锚索适应于大跨度硐室、交叉点、断层破碎带和受采动影响的巷道支护中 ,作为其它支护的补强措施 ,其工艺简单、支护及时、承载力大 ,是一种有效的补强支护新手段。 | | 文摘来源 | |   | | << 更多相关文摘 |
