一起倒闸现象的分析

通过对西站变电所倒闸操作中控制盘计量表计异常指示的分析,判断出电流经B3开关倒送到7#馈线的可能原因是A→2032→2042→高压母排2→B段母排有接续点接触不良或松动或母联隔开的铜铝过渡接线板处接触不良。经过实地测试,发现各接续点和铜铝过渡接线板连接牢固,接触电阻符合要求,现象产生的原因是6、7馈线末端并联的断路器在分位,6#馈线没有机车负荷,7 KX上有机车负荷引起的。

Some remarks on the dynamical conformity of rock joints

A recently developed computerized method for assessing the rock joint coefficients is discussed. The performances of formerly introduced relative similarity indicators, along with the correlation coefficient, are subjected to critical analysis. These relative numerical indicators are replaced by two absolute indicators whose properties better describe surface textures of rock joints. The first absolute indicator results from the Fourier Matrix and evaluates wavy shapes of surfaces. The second absolute indicator quantifies the heights of surface reliefs, and is defined as the root mean square height of the surface outline. The behavior of the newly introduced numerical indicators are investigated by means of the deterministic periodic surface reliefs. The practical application of the new indicators is presented and the convenient performances of both the indicators are documented.
