    • An electrical energy meter comprises an electrically insulating housing (10) for securing relative to least two main cables (22, 24) each having a conductive core surrounded by a sheath of insulating material. The housing includes respective electrical contacts for piercing the insulating sheath of each cable, a current probe for measuring current flowing in at least one of the cables, and circuit means for calculating and displaying electrical energy as a function of the voltage across the contacts and the output of the current probe. An improved current probe is employed comprising a series of Rogowski coils equally spaced around the circumference of a circle, with the gap between two adjacent coils permitting the current-carrying conductor to be introduced into the loop. An alternative current probe employs two such concentric loops of coils, enabling compensation for the effects of external current source pickup.
    • 电能表包括电绝缘壳体(10),用于固定相对于至少两个主电缆(22,24),每个主电缆具有由绝缘材料的护套包围的导电芯。 壳体包括用于刺穿每根电缆的绝缘护套的相应的电触头,用于测量在至少一根电缆中流动的电流的电流探针,以及用于计算和显示电能的电路装置,该电能作为触点两端的电压的函数 输出电流探头。 使用改进的电流探针,其包括围绕圆周等距间隔的一系列罗氏线圈,两个相邻线圈之间的间隙允许载流导体被引入回路中。 一个替代的电流探头采用两个这样的线圈同心环,可以补偿外部电流源拾取的影响。

    • An electro-mechanical electricity consumption meter (1) of a type having a sealed housing (2) to prevent tamper therewith is described. The meter (1) is adapted to include a rotatable component (11) which is visible through a portion (23) of the sealed housing (2) and whose rate of rotation is related to the rate of consumption of electricity. The component (11) has at least one marking (15) on a surface thereof such that the rate of rotation of the component can be determined using a monitoring assembly (24) located outside the sealed housing (2) without the need to access the interior of the meter (1). The, or each, marking (15) comprises a visually distinctive boundary between two surface areas (15, 16) of the rotatable component in which the boundary is transverse to the direction of movement of the component. In an alternative arrangement, an existing component (11) is adapted to have markings (15) on its surface. In a particularly preferred arrangement the rotating component comprises a part (11) of the magnet suspension arrangement of the rotor assembly (6).
    • 描述了具有用于防止篡改的密封壳体(2)的类型的机电用电量表(1)。 仪表(1)适于包括通过密封壳体(2)的部分(23)可见的旋转部件(11),其旋转速率与电力消耗率相关。 组件(11)在其表面上具有至少一个标记(15),使得可以使用位于密封壳体(2)外部的监视组件(24)来确定组件的旋转速率,而不需要访问 仪表内部(1)。 或者每个标记(15)包括可旋转部件的两个表面区域(15,16)之间的视觉上独特的边界,其中边界横向于部件的移动方向。 在替代布置中,现有部件(11)适于在其表面上具有标记(15)。 在特别优选的布置中,旋转部件包括转子组件(6)的磁悬浮装置的一部分(11)。
