また、実施の形態1において、開閉器は、遮断器あるいは断路器であるので、様々な開閉器のモジュール化が可能となる。さらにまた、モールド絶縁体14の外側表面は、導電性の塗料あるいは樹脂により接地されていてもよい。これにより、感電のおそれが減少し、安全性が高くなるのみでなく、モジュールを覆う筺体が不要となり、コストの削減が可能となる。さらにまた、電磁操作機構3は、固定側電極5aと可動側電極5bとの間の距離を例えば2段階に変更させることにより、可動側電極5bを遮断位置と断路器位置とに変更させ、開閉器を遮断器と断路器の複合開閉装置とすることができる。これにより、遮断器と断路器を同一電極で構成することが可能となり、スイッチギヤに必要な主回路構成の構築時に、部品点数の削減と、必要モジュール数の削減が可能となる。
In Embodiment 1, since the switch is a circuit breaker or a disconnector, various switches can be modularized. Furthermore, the outer surface of the mold insulator 14 may be grounded with a conductive paint or resin. This not only reduces the risk of electric shock and increases safety, but also eliminates the need for a housing that covers the module, thereby reducing costs. Furthermore, the electromagnetic operating mechanism 3 changes the distance between the fixed side electrode 5a and the movable side electrode 5b in, for example, two stages, thereby changing the movable side electrode 5b between the cutoff position and the disconnector position, and opens and closes it. The switch can be a combined switchgear of a circuit breaker and a disconnect switch. As a result, the circuit breaker and the disconnecting device can be configured with the same electrode, and the number of parts and the number of necessary modules can be reduced when constructing the main circuit configuration necessary for the switchgear.
