  • Page 3 ATTENTION: Southern States will begin supplying a portion of new operating mechanism designs with Rapid-Set clevises for orders designed after 9/1/23. If your Operating Mechanism print calls for Rapid-Set clevises (see image below for an example), please utilize the instructions on the following pages for all linkage adjustments.
  • Page 4 Please scan or use the link below for video instructions of Rapid-Set. Southern States Rapid Set Instructions S T E P 1 : Install the auxiliary arm by aligning the straight edge of the arm with the center of the vertical pipe and bolting it into place using two of the provided mounting holes.
  • Page 5 S T E P 2 : Install the adjustable arm with the radius “R” set to the recommended length provided in the operating mechanism drawings. S T E P 3 : Install the auxiliary arm Rapid-Set clevis and drive pipe. Ensure that roughly 12” of pipe extends beyond the adjustable arm clevis connection so that the pipe makes contact with the adjustable arm in the position shown.
  • Page 6 S T E P 4 : With the auxiliary arm properly aligned with the vertical pipe and the switch phase in the full closed position, pierce the pipe at both ends. NOTE: U-bolt style clevises require pre-drilling on all pipes thicker than SCH40.
  • Page 7 S T E P 6 : After the drive phase is adjusted to operate correctly, set all phases to full closed, and install the interphase pipe following the procedure below. For switches driven by the center phase: a. With the interphase pipe centered and all clevises in place, pierce the interphase pipe at the locations shown.
  • Page 8 For switches driven by one of the end phases: a. With the interphase pipe centered and all clevises in place, pierce the interphase pipe with at the locations shown. Do not remove plastic caps at this time. b. Adjust the timing of the center phase by adjusting the length “L” of the Rapid-Set clevis attached to the drive phase.
  • Page 9 c. Set the timing of the last phase by adjusting the length “L” of the Rapid-Set clevis attached to the last phase. S T E P 7 : With all the phases adjusted, open and close the three phase assembly and inspect for proper operation. Once adjustments are finalized, pierce all remaining connections (switch operator, adjustable arm, etc).

    Summary & Introduction Introduction Southern States switches designated RDA and RDA-1 that are rated 345kV come in current ratings of 1600, 2000, and 3000 continuous amperes. The illustration below shows the basic design configuration of these switch lines; however, individual differences may exist between models due to different mounting schemes, insulator types and sizes, and customer requirements.

    Page 5 of 23 Installation & Adjustment Procedures Installation & Adjustment Procedures Assembly The general procedure for installing these switches is as follows: 1. Uncrate the switches, remove the shipping ties, and check for damage in transit. If any damage is found, immediately file a claim with the carrier and notify the factory. 2.
  • Page 22 Page 6 of 23 Installation & Adjustment Procedures Figure 3: Insulator Mounting Spacers (“A”) are mounted above the corona shields (“B”) to maintain equal height of live parts when live part accessories are used. Otherwise, no spacers are supplied. 5. Use a plumb bob or level and true up the end insulators. It is important that they be perpendicular to the base in both planes.
  • Page 23 Page 7 of 23 Installation & Adjustment Procedures The rotating insulator requires special attention to ensure good switch operation. It is necessary that this stack rotate about its axis uniformly; that is, it must not “wobble” as it rotates. However, due to irregularities in the mounting faces of individual insulator units, it is not unusual for an insulator stack to be out of alignment six inches or more.
  • Page 24 Page 8 of 23 Installation & Adjustment Procedures Preparation Place a mark on the exact center of the rotating insulator Make a marker of any convenient material such as metal angle or lumber. Make a sharp pointer and attach it to the center of the marker. Place the marker over the center of the rotating insulator in such a manner that it can be used as a reference point but does not drag on the insulator top during rotation.
  • Page 25 Page 9 of 23 Installation & Adjustment Procedures TIMESAVING TIP for mounting live parts when hardware must be placed between the insulator and the live parts: Use two studs of sufficient length to allow later removal (easily made by cutting the heads off two bolts) to align the parts.

The blade tips must hit the stop in the jaws simultaneously (Figure 9). Minor misalignments can be corrected by tilting the jaw insulator stacks with the jack screws.

Corrective Procedure: The center insulator is not rotating true. Recheck adjustments described in Figure 5. Figure 12: Blade Tip Vertical Misalignment Blade tip attempts to move up or down during final blade rotation.

  • Page 38: Recommended Inspection Maintenance

    Recommended Inspection Maintenance Recommended Inspection Maintenance Southern States’ disconnect switches are designed to operate with minimum maintenance. While disconnecting switches are not readily serviced at frequent intervals, periodic inspection is important for satisfactory operation and maximized overall life. Frequency of inspection and maintenance depends on the installation site, weather, atmospheric conditions, experience of operating personnel, and any special operation requirements.
