<p>PROBLEM TO BE SOLVED: To obtain a switchgear capable of miniaturization and cost reduction. SOLUTION: This switchgear is equipped with a main circuit switching part 71 which is installed in a vessel and has a moving electrode 27 and a fixed electrode 26, and a ground switching part 172 which is installed in the vessel and has a moving electrode 129 and a fixed electrode 128. The electrodes 27 and 26 close and open a part between a bus side conductor 30 and a load side conductor 32. The electrodes 129 and 128 close and open a part between the load side conductor 32 and a ground side earthed conductor 33, and are smaller than the electrodes 27 and 26.</p> |
