Operation Sequence:First, open the load switch; then, operate the disconnector. When energizing the circuit, reverse this sequence.
Status Verification:Confirm the switch position by observing the mechanical indicator window; strictly avoid relying solely on signal lamps to determine the status.
Routine Inspections:Check the pressure gauge readings monthly, and visually inspect insulation components for any signs of surface tracking.
Anomaly Handling: If abnormal discharge sounds are heard coming from within the cabinet, immediately cut off the power supply; do not attempt to forcibly operate the switching mechanism.
