<p>PURPOSE:To provide a gas-blast circuit breaker having a drive mechanism of high efficiency of transmitting force with a simple structure such as capable of installing gas-blast circuit breaker total unit and facilitating installation construction in a work site. CONSTITUTION:A drive mechanism 57 is provided with a drive lever 63 rotated by a drive shaft 62 of a operating mechanism 56. The drive lever 63 is constituted so as to provided three branches protruded respectively in a different direction. Of the three branches, the one branch is connected through an idle rod 67 relating to a breaker part stored in a central earth vessel 52b of the three- phase breaker parts. The rest of two branches are connected respectively through individual idle rods 64, 68 to turnable individual levers 65, 69. The levers 65, 69 are connected through idle rods 66, 70 relating to a breaker part stored in both end earth vessels 52c, 52a.</p> |
