摘　　要：分析了机车采用动力制动对列车在长大下坡道上安全运行的重要作用、动力制动功率值与牵引功率值的关系及国外经验,提出我国机车动力制动的标称功率至少应达到机车牵引持续功率值。Adopting the dynamic brake is of great im portance in safe train operation on long and sharp grade. The paper states the relation between the power for dynamic brake and tractive power, introduces good experiences abroad. Besides,it proposes that the nominal power for locomotive dynamic brake in China should reach the continued power rate for locomotive traction at the minimun.

关 键 词：机车 动力制动 功率 安全
