At present, all substations have unattended conditions, but the switching of the secondary protection pressure plate is still on-site. When the mode is adjusted, the line is live, and the device sends an abnormal signal, it is necessary to send personnel to the unattended substation to perform manual switching. The operation of the pressing plate, and the substation is mostly far away from the operation team. Due to the influence of road and traffic, it takes a relatively long time to complete the operation task, which increases the system’s unsafe factors, and the operators need to go to the substation at least three times a day to manually switch on and off. Gate hard plate. Therefore, electric power enterprises have increasingly strong requirements for remote switching control of line reclosing gates. Due to the old version of the system currently used by the ground surveying system, there is no reclosing soft clamp graphic element in the electrical graphic library, and the remote control of the reclose soft clamp cannot be realized.
