  • Page 18: Installing The Operator

    Installation Installing the Operator CAUTION Do not attempt to set the operator upright by sling- ing to the skid. The skid is not designed to carry the weight of the switch operator . Damage to the operator and minor personal injury may result . Wrap a lifting sling around the stored-energy STEP 13.

  • Page 19: Connecting The Operator To The High-Speed

    Installation STEP 15. Reposition the lifting sling around the front of the stored-energy housing and wrap another lifting sling around the back of the stored-energy housing, Uni-ball as shown in Figure 21. Face the operator door the coupling same direction as the Switch Position indicator on the high-speed base.

  • Page 20: Connecting Conductors

    Installation Connecting Conductors STEP 19. DANGER Conductors must be de-energized and grounded in accordance with standard system operating practice . Failure to do so can result in serious injury or death . Attach the high-voltage conductors to their respective circuit- switcher terminal pads using flexible-conductor connections.

  • Page 27: Operation

    Operation Understanding Trip-Free Operation The stored-energy mechanism has an instantaneous trip-free capability. If the Series 2000 Circuit-Switcher is closed into a fault sensed by the user-furnished relaying, the mechanism will immediately trip. To accomplish trip-free operation, the stored-energy mechanism uses two spring assemblies: one for closing and one for opening.

  • Page 28: Manual Operation

    Operation To close the Circuit-Switcher, press the CLOSE pushbut- ton or send a remote close signal to the switch operator. See Figure 23 on page 22. The motor-driven cam in the stored-energy mechanism will immediately start retracting. The closing latch will release, discharging the closing spring.

  • Page 29: Understanding The Optional Remote

    Operation Understanding the Optional Remote Gas- Density Monitor The remote gas-density monitor provides local and remote indication of the gas-density in each interrupter in terms of percent full. The system can be wired to provide remote indication of the gas density of each interrupter via three analog 0 to 1.0 mA dc outputs.
