12月16日,中国电科院自主研发的直流换流阀成套运行试验装置顺利投运,标志着我国已具备世界最高合成试验电压80 kV、最大稳态合成直流试验电流6 kA、最大峰值故障电流55 kA的试验能力,打破了国外技术垄断,成为世界第三个同时具备高压大功率串联晶闸管阀和直流换流阀成套试验能 On Dec. 16, the complete set-up test set-up of DC converter valve independently developed by China Electric Power Research Institute shows that China has already had the world’s highest synthetic test voltage of 80 kV and the maximum steady-state synthesized DC test current of 6 kA with the maximum peak failure Current 55 kA test capability, breaking the monopoly of foreign technology, as the world’s third at the same time with high-voltage high-power thyristor valve and DC converter valve set of test
