    • A system for carrying electrical energy in connections in underground cables. In particular, it relates to a method of laying cables and a trench filler having a low thermal resistivity, used for laying underground cables for carrying electrical energy. More particularly, it relates to the use of an inert filler to be disposed in an area around the cables or the parts of the system, such as joints, which are disposed underground. The method of laying cables disposed in a trench includes: removing the original soil to prepare the trench; disposing a first layer of a first composition in the trench; disposing the cables on top of the first layer; disposing a second layer of the first composition on top of the cables; disposing a third layer on top of the second layer formed by a second composition to fill the trench. The first composition comprises: 60-90% by weight of crushed sand; 4-15% by weight of silt; 2-12% by weight of cement; and 4-15% by weight of water.
    • 在地下电缆连接中承载电能的系统。 特别地,本发明涉及一种铺设电缆的方法和具有低热阻的沟槽填料,用于铺设用于承载电能的地下电缆。 更具体地,涉及使用惰性填料来设置在电缆或系统的诸如接地处的地下部分的区域中。 布置在沟槽中的敷设电缆的方法包括:去除原始土壤以准备沟槽; 在沟槽中设置第一组合物的第一层; 将电缆布置在第一层的顶部; 将第一组合物的第二层设置在电缆的顶部上; 在由第二组合物形成的第二层的顶部上设置第三层以填充沟槽。 第一组合物包括:60-90重量%的碎砂; 4-15重量%的淤泥; 水泥2-12%; 和4-15重量%的水。

    • A method and system for transporting electric power in a link and for the analysis of the status of an electric power transmission link and the relevant current rating capability control. The method includes dividing the link into a predetermined number of segments, each segment having an associated prediction model and at least two associated temperature sensors. Upon receiving sensor values, an expected operating condition in one of the segments is determined based on the sensor value and the electric current value. Next, an actual operating condition in the segment is determined and compared with the expected operating condition. If there is a difference between the conditions, a second predetermined prediction model is associated with the segment.
    • 一种用于在链路中传送电力并分析电力传输链路的状态以及相关的电流额定能力控制的方法和系统。 该方法包括将链路划分成预定数量的段,每个段具有相关联的预测模型和至少两个相关联的温度传感器。 在接收到传感器值时,基于传感器值和电流值来确定其中一个段中的预期操作条件。 接下来,确定段中的实际操作条件并将其与预期操作条件进行比较。 如果条件之间存在差异,则第二预定预测模型与段相关联。
