<p><P>PROBLEM TO BE SOLVED: To provide a gas-blast circuit breaker which reduces operation vibration added to the setting floor surface of the circuit breaker, through an extremely simple constitution, and which is simplified in the constitution and excellent in maintenance properties. <P>SOLUTION: The operation mechanism boxes 2a to 2c and tanks 3a to 3c in single-phase circuit breakers 1a to 1c are laterally connected, and respective tanks 3a to 3c are radially disposed at an angle interval of 120°from a predetermined center point. The operation mechanism boxes 2a to 2c are attached to the end on the center side of the single-phase circuit breakers 1a to 1c when viewed from the radial center point. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
