通过对电阻制动元件结构进行分析,找出SS3及SS3B型电力机车电阻制动元件烧损的主要原因,并在SS3系列电力机车电阻元件上增加瓷夹组数,改进后效果明显。
Through the analysis of the structure of the resistance braking element, the main reason of the burning of the resistance braking element of the SS3 and SS3B electric locomotives is found, and the number of the porcelain clamps is added to the resistance element of the SS3 series electric locomotive. The improvement is obvious.
