<p>PROBLEM TO BE SOLVED: To reduce the installation space of a generation plant by accommodating a transformer for measuring instrument and a surge absorber in a second metal container accommodating the operation device of a breaking part and an isolating part. SOLUTION: First and second insulation support members 67 and 68 are arranged on a second metal container 74 as a support trestle, that is connected to the lower portion of a first metal container 71. Also, first and second insulation bushings 83 and 85, that are arranged through the connection part of the metal containers 71 and 74, are connected to a breaking part fixation side conductor 57 and an isolating part movable side conductor 64 with connection wires 84 and 86, respectively. A breaking part operation device 75, an isolating part operation device 77, a breaking part grounding operation device 79, and an isolating part grounding operation device 81 are arranged in the second metal container 74. Also, a transformer 87 for a measuring instrument that is arranged in the second metal container 74 is connected by the first insulation bushing 83 and a connection wire 88. Similarly, a transformer 89 for measuring instrument and an adjacently arranged surge absorber 90 are connected to the second insulation bushing 85 with a connection wire 91.</p> |
