Fix the vertical connecting rod: Connect the other end of the telescopic arm (8) to the V-shaped clamp (9), fix the vertical connecting rod with the V-shaped clamp (9), adjust the position of the V-shaped clamp (9) so that it fits the vertical connecting rod (3) without shaking, check whether the entire vertical connecting rod fixing device is stable, and ensure that the disconnector body will not rotate or move during the replacement process; Step 4: Remove the manual operating mechanism and install the electric operating mechanism, including the following steps: S14. Dismantle the manual operating mechanism: loosen the fixing bolts of the old operating mechanism, gradually remove the connecting parts, and protect the vertical connecting rod (3) and its connection point to avoid impact or displacement during operation; S15. Install the electric operating mechanism: Align the output shaft (4) of the electric operating mechanism with the bottom end of the vertical connecting rod (3) and connect them with an elastic coupling to ensure that the two are aligned. Adjust the fixed position of the electric operating mechanism to align it with the opening on the top of the disconnector mechanism box. Tighten the fixing bolts of the electric operating mechanism to ensure stability. Step 5, testing and verification, includes the following steps: S16, power-on test: Turn on the power of the electric operating mechanism, simulate the opening and closing operations through the control circuit, observe the operating status of the new mechanism, and ensure that its operation is smooth and without jamming; S17, verifying the open and closed positions: checking whether the positions of the disconnector in the open and closed states are consistent with the simulation results, and using a rotation angle measuring device to verify the rotation angle of the vertical connecting rod (3); S18, fine-tuning the limit bolt: If the deviation between the open and closed positions is large, stop the operation and readjust the position of the limit bolt (6) to adjust the rotation angle to ensure that the adjusted angle meets the simulation requirements; S19, Operation stability test: Run the disconnector opening and closing operations for multiple times, observe the working status of the electric operating mechanism, and check whether there is abnormal noise, vibration or jamming during operation; S20, Final calibration and recording: Confirm that the connection and adjustment of all components meet the design requirements, record the adjustment results, and save the simulation files and field test data for subsequent maintenance reference.
