[0002] At present, the major training institutions in the industry provide training programs for the shutdown and power-on operations of transmission lines, which are single 10kV transformer drop insurance shutdown and power-on operations. The training programs are single and limited by the space of the training institutions. The voltage level of the equipment and the electrical equipment such as hardware fittings and insulators are all lower than the actual operating conditions of the wind power 35kV transmission line.

[0003] The existing practical training platform for power transmission lines cannot truly simulate the composition of a 35kV transmission line system.

[0082] In some embodiments, the data analysis device is specifically used to determine whether the actual opening and closing timing information is consistent with the preset opening and closing timing information. If so, the opening and closing operation is determined to be qualified and the training qualified information is output; if not, the opening and closing operation is determined to be unqualified and the training unqualified information is output; wherein the comparison result information is the training qualified information or the training unqualified information.

[0083] For example: when the wind direction information is downwind direction information and the phase fault information is phase A fault, if the practical operation steps are, in sequence, pulling the drop fuse corresponding to B, pulling the drop fuse corresponding to C, closing the drop fuse corresponding to C, closing the drop fuse corresponding to A, and closing the drop fuse corresponding to B; then the timing signals in the corresponding practical opening and closing timing information are, in sequence, the second opening discrete time signal is high and the second closing discrete time signal is low, the third opening discrete time signal is high and the third closing discrete time signal is low, the third opening discrete time signal is low and the third closing discrete time signal is high, the first opening discrete time signal is low and the first closing discrete time signal is high, the second opening discrete time signal is low and the second closing discrete time signal is high; it can be seen that the practical opening and closing timing information is consistent with the preset opening and closing timing information, then the opening and closing operation is determined to be qualified and the training qualified information is output.

[0084] When the wind direction information is downwind direction information and the phase fault information is phase A fault, if the actual operation steps are, in sequence, pulling the drop fuse corresponding to C, pulling the drop fuse corresponding to B, closing the drop fuse corresponding to A, closing the drop fuse corresponding to C, and closing the drop fuse corresponding to B; then the timing signals in the corresponding preset opening and closing timing information are, in sequence, the third opening discrete time signal is high and the third closing discrete time signal is low, the second opening discrete time signal is high and the second closing discrete time signal is low, the first opening discrete time signal is low and the first closing discrete time signal is high, the third opening discrete time signal is low and the third closing discrete time signal is high, the second opening discrete time signal is low and the second closing discrete time signal is high; it can be seen that if the actual opening and closing timing information is inconsistent with the preset opening and closing timing information, the opening and closing operation is judged to be unqualified and the training unqualified information is output.

[0085] Through the travel switch installed at the drop insurance, the 35kV terminal tower three-phase drop insurance position switch quantity is introduced into the PLC input contact. After the examiner specifies the on-site wind direction through the control platform, the wind direction information is input into the display screen, the on-site drop insurance information is manually judged to be intact and the status switch quantity information is manually entered. According to the opening sequence of the drop insurance under different faults or normal conditions, the operation sequence logic of the A, B, and C three-phase drop insurances is programmed. If the trainee completes the operation according to the correct process, the voice output is "Congratulations, you passed the test". If a misjudgment occurs during the operation or the operation is not performed according to the standard process, the voice output is "Unfortunately, you failed the test" to terminate the operation. The intelligent drop insurance operation assessment system strengthens the trainees' standardized operation of electrical equipment by solidifying the operation process to prevent electrical misoperation incidents.

[0086] The embodiment of the present invention realizes the simulation of the terminal tower in the actual power grid by building a high-voltage collector line training terminal tower similar to the actual line terminal tower and setting a drop fuse on the high-voltage collector line training terminal tower. Then, by setting the simulated training information, the trainees can operate the drop fuses of each phase through the training information, and record the opening and closing sequence of the trainees' operation of each drop fuse through the data acquisition device, so as to judge whether the trainees' operation is qualified through the opening and closing sequence. Compared with traditional practical training and assessment, the present invention does not require on-site assessment personnel to provide on-site guidance and judgment, and can judge the assessment results of the operators by themselves through the equipment, thereby improving the efficiency and effect of the training of the drop fuse power outage operation of the high-voltage transformer.
