<p><P>PROBLEM TO BE SOLVED: To obtain a gas circuit breaker which reduces cost and improves the reliability on setup, by minimizing the setup work and test in a factory and on site. <P>SOLUTION: The gas circuit breaker includes a grounding tank 1 for two or more phases, a bushing 2, an upper housing 3, a lower housing 4, a base 5 on which the grounding tank 1 of each phase where the bushing 2 is installed, the upper housing 3, and the lower housing 4 are installed, and a frame 8 which supports a base 5 on which the grounding tank 1 of each phase where the bushing 2 is installed, the upper housing 3, and the lower housing 4 are installed. The gas circuit breaker includes a hinge structure which switches the lower housing 4 from a first state for operation where it is arranged under the upper housing 3 and the grounding tank 1 to a second state for transportation where it is installed on roughly the same level as the upper housing 3 and the grounding tank 1 and vice vesa. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
