Abstract: This research designs an intelligent electrical operating device to verify the operational performance of an external operating lever disconnector which used to realize thousands of on-load/no-load operation opening and closing cycles. The device consists of a lifting test-bed, electrical power system, and electrical control system. This paper used the lifting test-bed to evaluate load-bearing and center of gravity displacement during operation and adjusted load-bearing steel structure by hydraulic pressure to meet the demand of load stability.The electrical power system employed the servo motor to fit various coupling joints, occlude the operating shaft of isolating switch to realize multi-applicability. The electrical control system stably controlled the motor rotation rate and the opening and closing position of the switch.It used a fuzzy self-tuning PID control algorithm for feedback regulation and realized high-precision control of the motor rotation position.The test results showed that the device could realize electrical intelligent control operation of the disconnector, and the reliability of the operation was ensured under thousands of experiments.
Key words: disconnector; operational performance; electrical operation; fuzzy self-tuning PID control algorithm
