    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 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 16 Page 6 Installation & Adjustment Procedures Figure 3: 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 17 Page 7 Installation & Adjustment Procedures Figure 4: Jack Screw Adjustment • To adjust the insulator stack, first loosen all four nuts (A). Tilt the insulator to the required position by screwing up or down on nuts (B). Re-tighten nuts (A). The rotating insulator requires special attention to ensure good switch operation.
  • Page 18 Page 8 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 19 This procedure can cut a significant amount of time from installation, and will work in all cases except on the center insulator of the double-side-break RDA, RDA-1, and RDC switches. Where alignment difficulties are encountered with the center stack on double side break switches, match mark and remove the top insulator unit (after adjustment for concentric rotation) and bolt the parts together on the ground, where alignment will be easier.

The jaws also may be mounted at this time. Note: If applicable, at this time also mount accessories such as: grounding switch jaw, quick break devise, outriggers, etc., as shown on the Op.

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.

    Page 12 Installation & Adjustment Procedures Contact Misalignments and Corrective Procedures A. Blade tip moves, or attempts to move, vertically, during final rotation in contacts. Corrective Procedure: The center insulator is not rotating true. Recheck adjustments described in Figure 5. Figure 12: Blade tip attempts to move up or down during final blade rotation.
  • Page 23 Page 13 Installation & Adjustment Procedures • Corrective Procedure for Misalignments “B” and “C” on previous page: If either condition “B” or “C” is encountered, and if it is certain that both jaw insulator stacks are properly plumbed, it will be necessary to adjust the rotating insulator bearing.

Included with every switch is an Operating Mechanism Drawing (Op. Mech. Drawing). Study this drawing carefully, and with all switch poles closed, install mounting brackets, bushings, manual operation devices (if used), vertical pipe, adjustable crank arm, reach rod, and interphase pipe.
  • Page 28 Page 18 Installation & Adjustment Procedures Figure 22: Adjustable arm assembly Pipe collar must support full weight of pipe. 5. ADJUSTMENT: If a motor operator is used, DO NOT use electrical operations until all adjustments are made. All grounding switch poles should be closed, all line switch poles open.

  • Page 32 Page 22 General Instructions for Threaded Clevises Be sure the initial setting is correct, and do not adjust beyond the maximum allowable dimension. If adjustment beyond the maximum allowable dimension is needed loosen the U-bolts on the outboard phase clevis and reposition the pipe toward the center phase.
