Single Bottle Interrupter

Single Bottle Interrupter

SEECO manufactures a single bottle interrupter for those applications where the recovery voltage does not exceed 30 kV peak and the maximum interrupting current is 3000 amps or less.  Less expensive than multi bottle interrupters, single bottle devices offer substantial cost savings but with reduced functionality and more limited switching applications.  An off-setting disadvantage can be the occasional confusion experienced by field personnel who often struggle with understanding the limitations of the single bottle device relative to the broader functionality of the multi bottle interrupter.   Single bottle interrupters can be installed initially with the switch or added later as a field retrofit or upgrade.

Common switching applications for single bottle interrupters include:

• Load dropping – 70% pf of load interruption up to 25 kV on ungrounded systems and 34.5 kV on solidly grounded systems

• Line dropping – to 25 kV or 72.5 kV with voltage limiter

• Loop splitting (parallel break) – to 230 kV if recovery voltage does not exceed 30 kV peak
