Provided is a power switchgear having a current transformer having a small size, a light weight, and reduced fabrication steps. The power switchgear is equipped with a current transformer (21) for measuring current flowing through a circuit of a power system, switches the current flowing through the circuit, and is characterized in that: the current transformer (21) is configured by winding a coil (32) around a circular ring-shaped iron core (31); and a high thermal conductivity member (40) is disposed between the iron core (31) and the coil (32). |
