    • A method and means for diagnosing transformer tap changers is provided. Pressure is monitored in an insulating liquid of a tap changer for a period of time in which switching of the tap changer is carried through. Switching-related information is then extracted from the pressure diagram. The method, preferably used for single-phase tap changers, comprises the step of relating quantities from pressure peaks to specific arcings of the switching sequence. Early error detection is achieved, whereby transformed failures may be avoided. Repeated measurements ae followed by trend evaluation. If a trend indicating tap changer problems is detected, an alarm signal is triggered. The invention may include switching off the transformer if the pressure exceeds a predetermined emergency value as well as extracting information of the base pressure in the tap changer and converting it to level of insulating liquid.
    • 提供了用于诊断变压器抽头变换器的方法和装置。 在分接开关的绝缘液体中监测压力,持续一段时间,分接开关切换进行。 然后从压力图中提取开关相关信息。 优选用于单相抽头变换器的方法包括将来自压力峰值的数量与切换序列的特定弧形相关联的步骤。 实现早期错误检测,从而可以避免变形的故障。 重复测量,然后进行趋势评估。 如果检测到指示分接开关故障的趋势,则触发报警信号。 如果压力超过预定的紧急值,本发明可以包括关闭变压器,以及提取分接开关中的基础压力的信息并将其转换成绝缘液体的水平。

    • A device for influencing light has a polarizer, a ferroelectric or electroclinic response type liquid crystal halfwave plate whose liquid crystals are in the smectic phase with bookshelf geometry and have molecular axes which are rotatable around a first direction corresponding to the direction of incoming light in response to an electric field applied across the electrodes on either side of the halfwave plate, a quarter wave retarder plate, and a mirror. The polarizer, plates and mirror are arranged such that incoming light is passed from the polarizer through the liquid crystal plate and the retarder plate, and is reflected by the mirror in a second direction opposite to the first direction back through the retarder and the liquid crystal plate so as to provide a reflected polarized light plane to the polarizer. The polarizer has a first polarization direction set parallel to one electrically selectable molecular axis direction of the liquid crystal molecules, which is selected in response to a first electric field level. The retarder plate has its slow axis inclined either 45.degree. or 135.degree. relative to the optic axis of the liquid crystal. The liquid crystal, furthermore, is of a material which produces an angular difference 2.theta. in optic axis direction in response to a second electric field level whose polarity is opposite that of the first electric field level. This allows the device to rotate the reflected polarized light plane by an angle of 8.theta. in response to the second electric field level.
