Switchgear and switchgear operating method

摘要

The present invention provides switchgear that contributes toward the formation of a smart electrical distribution network. The switchgear provided by the present invention includes a main circuit, a bus bar 60, a disconnector 121a, 121b, 121c, and a load-break switch 10. The main circuit includes a main disconnector 111a, 111b, 111c capable of selectively closing or opening a circuit and a cable 42a, 42b, 42c connected to one end of the main disconnector 111a, 111b, 111c. The bus bar is connected to the other end of the main disconnector 111a, 111b, 111c. The disconnector 121a, 121b, 121c is disposed in parallel with the main disconnector 111a, 111b, 111c. The load-break switch 10 is disposed in parallel with the main disconnector 111a, 111b, 111c and in series with the disconnector 121a, 121b, 121c.
