Switchgear

A switchgear comprising:

• a tank having a first through hole formed therein;
• three fixed contacts accommodated in the tank;
• three movable contacts capable of reciprocating between a position in contact with the three fixed contacts and a position separated from the three fixed contacts;
• an operating rod capable of reciprocating in a direction parallel to a direction of movement of the three movable contacts, the operating rod penetrating through the first through hole;
• a connecting plate connecting the three movable contacts and the operating rod, the connecting plate to be movable with the three movable contacts and the operating rod;
• a shielding plate disposed closer to the three fixed contacts than the connecting plate and fixed to the tank, the shielding plate having a second through hole and three third through holes formed therein, the operating rod penetrating through the second through hole, each of the three movable contacts being capable of passing through a corresponding one of the third through holes;
• a first bearing provided in the first through hole to support the operating rod;
• and
• a second bearing provided in the second through hole to support the operating rod,
• wherein:
• each of the three fixed contacts and each of the three movable contacts are disposed at a vertex of a respective triangle when viewed from a direction parallel to the direction of movement of the three movable contacts, and
• the operating rod is connected to the connecting plate at a position corresponding to a center of gravity of the respective triangle when viewed from a direction parallel to the direction of movement of the three movable contacts.
