The Joslyn Universal Vac-RupterÒ Interrupter (UVI) converts an isolating switch into a load interrupter switch. The Vac-Rupter allows the switch to be used for full load interruption up to 34.5kV or for the reduced recovery voltage application of loop splitting or parallel switching up to 230kV depending upon system voltage, grounding considerations of the system and load, and the characteristics of the load.
Universal Vac-Rupters can be quickly mounted on most types of group operated isolating switches of all manufacturers. Conversion of an existing air switch is easily achieved since no special tools or training is required. Procedures are simple for installing the interrupter, fixed and moving arc horns, and verifying proper operation. Adding a Vac-Rupter will not affect the mechanical operation of the switch.
|Long life of 5,000 operations.|
|Ease of Installation|
|Three phase sets can be installed quickly and easily in approximately 4 hours.|
|Anodized aluminum mechanism housing protects against corrosive action and sealed vacuum interrupter chamber is sealed against moisture, ultraviolet activity, and contamination - no SF-6 gas or oil is used.|
|Interruption is noiseless and liberates no hot exhaust or ionized gases.|
|Installations of more than 35 years demonstrate the reliability and proven performance of the interrupter.|
|Air Switch Ratings Unaffected|
|The continuous, momentary, and impulse ratings of the switch are unaffected since the UVI is in the power circuit for a few seconds.|
