为节省投资，研制的电气传动系统利用了６Ｙ＿２型电力机车的牵引电机、平波电抗及制动电阻设备；采用加馈制动及高精度稳速技术，简化了试验台的结构。本文对该传动系统的机电配置，主电路构成及调节系统结构等关键问题进行了分析和论述。
In order to save investment, the electric drive system developed utilizes the traction motor, the smoothing reactance and the braking resistance equipment of the 6Y_2 electric locomotive. The adoption of feed-in braking and high-precision steady speed technology simplifies the structure of the test bench. This paper analyzes and discusses the key problems such as the mechanical and electrical configuration, the main circuit structure and the adjustment system structure of the transmission system.
