| 摘 要： | 提出了一种应用可控硅技术并采用全新的高短路阻抗变压器式可控消弧线圈的新的谐振接地消弧系统。消弧线圈由一个一次线圈及两个二次线圈构成，通过两组SCR控制消弧线圈二次电流，结合电流调节算法能有效抑制谐波，系统电抗具有优良的伏安特性，采用拟合曲线法确定可控硅的导通角与消弧线圈补偿电流的关系。模拟实验与现场运行验征了设计的有效性。

| Abstract: | This paper introduces a new system of arc extinguishing coil. It consists of one primary coil and two secondary coils. By using two SCRs for the secondary coils to control the currents flowing by means of harmonic suppressing algorithm, the inductance viewing from the primary side is linear. The actual device based on the above principle shows that its operating volt-ampere characteristics is good. Through proper method for regulating the secondary current, the harmonics occurring with SCR control can be suppressed effectively. The simulation experiment and the actual operation prove that the design is successful. |
