PROBLEM TO BE SOLVED: To provide a three-phase bulk operation circuit breaker which allows for compaction of a gas-insulated switchgear.SOLUTION: A three-phase bulk operation circuit breaker consists of three interrupt section tanks 2, 3, 4 each having an interrupt section internally and filled with insulation gas, an operation unit for switching the interrupt section, and a drive mechanism 5 for transmitting the drive force of the operation unit to the interrupt section. The operation unit consists of a drive motor 8, and a control/power supply section 9 for outputting a switching command to the drive motor 8. The drive motor 8 is provided in the vicinity of the drive mechanism 5, the control/power supply section 9 is disposed in a place different from the drive motor 8, and the drive motor 8 and control/power supply section 9 are connected electrically. |
