MEDIUM VOLTAGE SWITCHGEAR FOR USING PIPE TYPE BUSBAR AND AIR BLOWER

摘要

PURPOSE: A medium voltage switchgear using pipe busbar and air blower are provided to cool down the heat temperature due to the amount of used current by enforcing the suction or ventilation of the heat. CONSTITUTION: A first busbar(310) takes the form of cylinder having a hollow inside the busbar. One end of a first busbar(310) is directly connected to the main circuit breaker or the branch blocker. A second busbar(320) extends in a direction perpendicular to the first busbar. One side of the second busbar comprises a suction blower(500) or a ventilation blower(500).
