Recently, a controllable reactor model which can be used ultra-high or super-high voltage power network construction has been manufactured, this model is made to the scale of 100:1 include the complete part of the real reactor and its static, dynamic Characteristics which can be used to the research, development and experiment of the similar product and the provision of the elative experiment data. The real reactor of the model will be used as a test on the spot important product in the 500kV converter station in Jingzhou which is an ultra-high 500kV transmission and transformation project in China. The practical application of the reactor will fill the vacant of high voltage controllable reactor in China.
