POWER GENERATION MAIN CIRCUIT SWITCH |
摘要 |
A power-generation main circuit switchgear 1 includes a casing 1e with an axial direction thereof being an extending direction of an isolated-phase bus 2, internal conductors 1a and 1b arranged in the casing 1e and constituting a breaking unit 10, a duct 5 provided on the casing 1e and communicating with a space inside the casing 1e through a plurality of vent holes 5a and 5b, and a blower 4 arranged in the duct 5 to blow wind in the axial direction. The vent hole 5a is provided on the upstream side of the blower 4 and the vent holes 5b are provided on the downstream side of the blower 4. Wind blowing from the blower 4 circulates inside the duct 5 and inside the casing 1e through the vent holes 5a and 5b, and wind blowing from the inside of the duct 5 to the inside of the casing 1e through the vent holes 5b directly hits the internal conductors 1a and 1b |
