SS_3型电力机车是1978年设计的,到1985年共生产22台,已在线路上投入运用。由于当时因生产周期问题,未能对车体进行静强度试验,八六年三月份,在工厂领导的重视下,由电力机车研究所机械室负责对车体进行了静强度试验。 SS_3型电力机车车体的底架长度为20200毫米,车体总长度为21416毫米,车顶高度(至轨面)为4359毫米,,车体宽度为3106毫米,车体两端各有一个司机室,除司机室顶盖与司机室骨架焊接为一体外,其中部有五个活动顶盖。在活动顶盖分界处,焊有连接两侧墙的横梁(共6根),侧墙为框架式
SS_3 electric locomotive was designed in 1978, a total of 22 production by 1985, has been put into operation on the line. Due to the production cycle at that time, the static strength test of the vehicle body was not conducted. In March 1986, under the leadership of the factory, the static strength test of the vehicle body was carried out by the machine room of the Electric Locomotive Research Institute. SS_3 electric locomotive chassis length of 20,200 mm, the total body length of 21416 mm, the roof height (to rail) is 4359 mm, body width of 3106 mm, the body at each end of a driver Room, in addition to the driver’s cab roof cab and chassis welding as one, there are five activities in the middle of the roof. In the activities of the top of the demarcation, welded to connect the two sides of the wall beams (a total of 6), the side wall of the frame
