The method of equivalent complex puncturing depth is proposed to calculate mutual inductance between current and voltage leads under multi-layers soil st...

该方法在某50 0kV变电站的接地阻抗测试中进行了实际应用,如果不考虑测量引线间的互感,在本文的实例中可导致接地阻抗增加 7 3%,影响是比较大的。本文提出的方法可为电力部门提供参考。

A multiplayer chip LC resonator was fabricated using planar inductor and parallel plate capacitor. Because lumped inductor has small Q value and there is stray parameter effect in high permittivity substrate, the Q value of chip LC resonator is not high. Resonators based on λ/4 stripline with end short circuited were designed and fabricated. Input and output pads, coupled to the stripline using gap-coupling capacitor, are in the same layer with the center conductive strip. This new structure is very convenient for manufacturing in comparison with the conventional structure.

采用间隙电容耦合结构实现的谐振频率为1.8GHz四分之一波长终端短路带状线单端口谐振器的Q值最大值为225,谐振频率为1GHz双端口谐振器的Q值为83,谐振频率和Q值与耦合间隙、带状线的厚度和耦合引线长度有关;二分之一波长带状线谐振器的Q值和四分之一波长相比较尺寸较大,由于导电带较长,造成金属的损耗增加,从而导致谐振器的Q值较低;带状线结构的谐振器频率调节困难,本文提出了改变接地端的宽度实现谐振频率的微调方法,可实现频率调节量约1.5%。

Grounding grid is essential to the safety of substation, however, the corrosion caused by earth may result in thinness even break of the grounding down-lead and horizontal equal-voltage conductor. This will lead to fault spread when grounding fault occurs, and will be dangerous to human and facilities.

接地网对变电站安全运行至关重要,但土壤的腐蚀可能使接地引线和水平均压导体变细甚至断裂,当系统发生接地故障时可能造成事故扩大,危及设备和人身安全。
