In view of the lack of flexibility in the input and exit of the current metal sheath loop suppression device for high voltage cables，the problems such as excessive induced voltage of the sheath and excessive power loss were not considered when determining the suppression impedance value，a loop suppression device was designed which could dynamically input or exit the loop suppression impedance of the sheath according to the field conditions. Firstly，the structure and operation flow of the suppression device was described. Then，the variation characteristics of sheath circulation，induced voltage and sheath loss when the suppression impedance was pure resistance，pure inductance and combined resistance inductance were analysed. On this basis，an optimization model was established to solve the optimal impedance value which can minimize the power loss when meeting the requirements of sheath circulation and induced voltage. Based on the optimal impedance value，the parameters of thyristors and other components were configured. The results show that the proposed method can obtain the optimal value of cable suppression impedance that meets the engineering requirements，and achieve a good circulation suppression effect.
