<p><P>PROBLEM TO BE SOLVED: To provide a gas insulated switchgear in which a space for dismantling inspection work is assured when a circuit breaker fails, and installation area can be reduced. <P>SOLUTION: A space (S1) for dismantling inspection work is formed between two adjoining circuit breakers 3 and 4 out of three circuit breakers 3-5 connected between main buses 1 and 2. By utilizing the common dismantling inspection work space furthermore, branch buses 14 and 16 are arranged above while intersecting the insulation lead-out directions in order to balance the voltage. Even if the three circuit breakers 3-5 are arranged in the axial direction of the main buses 1 and 2, installation area can be reduced in the juxtaposing direction of circuit breakers by sharing the dismantling inspection work space and arrangement of the branch buses 14 and 16. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
