Abstract

PURPOSE:To control the temperature rise of a conductor placed in a bus-duct by letting cooling water of a semiconductor rectifier flow through a waterpipe attached to the conductor. CONSTITUTION:A semiconductor rectifier 1 is connected to an equipment in a building via DC conductors 3, 4 and 5 in a bus-duct. Cooling water which cools semiconductor elements in the rectifier 1 is supplied to a waterpipe 9 attached to the conductor 3 and cools the conductor 3.
