    摘 要:基于TCR(晶闸管控制电抗器)阀组正常运行时候的电压、电流应力的特点,给出了一种应用于TCR 双向晶闸管阀组的合成回路试验方案。通过Y 型TCR连接的方式实现TCR大电流的输出,通过直流电压源和电压振荡回路实现阀组大电压的施加,并完成了最高电压110 kV、最大电流4 000 A合成回路试验系统的建设。在此试验回路中完成额定电压20 kV、额定电流2 700 A的TCR阀组的运行试验,试验结果表明,该试验系统完全能够满足IEC和国标中对TCR阀组型式试验的要求,可以完成阀组全工况性能测试,大大加快TCR阀组的开发速度并保证所开发阀组的性能。

    Abstract: Based on the characteristics of the voltage and current stress during the normal operationofthyristor control reactor (TCR) valve bank, this paper gave a synthetic circuit test scheme for TCR bidirectional thyristor valve bank.The Y type connection mode was used to realize the big current output of TCR and the direct current voltage source and the voltage oscillation circuit was used to realize the infliction of valve bank big voltage. On this basis, a test system with the highest voltage of 110 kV and a maximum current of 4 000 A was built. In this test circuit the running test of TCR valve bank with nominal voltage of 20 kV and nominal current of 2 700 A was completed. The test results show that the test system can fully meet the requirements of the TCR valve type test which was requested in IEC and national standard, and it can complete the full operating performance test.Through the use of the synthetic circuit, the development speed of TCR valve can be greatly accelerated, and the developed valve can be guaranteed.
