However, in the switchgear constructed as described above, the mounting interval between the vacuum circuit breaker 42 and the wire-type current transformer 51 may be stuck on the surface during a long-term operation. Alternatively, since the size of the box must be large in consideration of the accumulated dust, the outer shape of the box increases, and the floor area of the installation location increases. In addition, especially in places where the installation environment is bad, frequently cut off the upstream circuit breaker to stop the load,
Since dust on the surface of the insulator of the main circuit device must be removed, not only maintenance is required, but also the load operation rate is reduced. Therefore, in particular, a switchgear installed in a substation in an urban area cannot cope with a switchgear having such a large installation area due to soaring land prices.
