In Power Systems, asynchronous opening and closing of disconnect switches may lead to abnormal equipment operation and affect system safety. First, the mechanical condition of the operating mechanism should be inspected to ensure proper lubrication and the absence of jamming. Next, verify that the control circuit is functioning correctly to avoid malfunctioning due to insufficient voltage or electrical faults. Regular calibration of the contact positions and travel is also necessary to ensure accuracy. If the switching operation times are found to be inconsistent, adjustments should be made to the corresponding displacement detector or travel switch. In addition, for equipment that frequently experiences asynchronous behavior, installing a time relay can be considered to achieve more precise control of the opening and closing actions. These measures can effectively prevent instability of the disconnect switch under high-current conditions and enhance the reliability of the entire power system.
