The invention relates to an arc-extinguishing end elbow, and belongs to equipment for urban rail transit power supply. A steel-aluminum composite conductor rail is bent upwards at the gradient of 1: 20, and enamel is coated on the slope, so that arc extinction is realized when a current collector electric brush on an electric locomotive leaves the steel-aluminum composite conductor rail, and electric sparks are reduced or not generated. The service lives of the end elbow and the electric brush can be prolonged, and the running speed of the electric locomotive is improved.
本发明涉及一种消弧的端部弯头,属于城市轨道交通供电用的设备。其主要采用钢铝复合导电轨以1∶20的坡度上弯,并在斜坡上涂搪瓷,使电力机车上的受电器电刷离开钢铝复合导电轨时消弧,减少或不产生电火花。可延长端部弯头和电刷的使用寿命,提高电力机车运行速度。
