SWITCHGEAR

摘要

A switchgear (100) is provided with a switch mechanism (103) that can connect or disconnect a movable contact (2a) to/from a fixed contact (1a); a magnet (4) that generates a magnetic field for extending an arc generated when the contacts (1a) and (2a) separate; and an elongated magnetic body (3), one end of which is in contact with a magnetic pole face of the magnet. The other end of the magnetic body (3) is disposed near an arc-generating area between the fixed contactor (1) and the movable contactor (2), and the magnetic field generated by the magnet (4) extends the arc along a longitudinal side face of the magnetic body (3).
