The invention discloses an electrified highway pantograph head with a self-protection function and a pantograph. The pantograph head comprises a positive electrode sliding plate and a negative electrode sliding plate, second pantograph angles are installed at the inner end of the positive electrode sliding plate and the inner end of the negative electrode sliding plate respectively, each second pantograph angle comprises a fixed pantograph angle and a limiting insulating plate parallel to the fixed pantograph angle, and the upper end of each fixed pantograph angle is fixedly connected with the inner end of the positive electrode sliding plate or the inner end of the negative electrode sliding plate. The lower end of the limiting insulating plate is hinged to the limiting insulating plate, a reset spring and a triggering mechanism are installed between the limiting insulating plate and the fixed bow angle, and the limiting insulating plate has two working states: when the contact net line slides within the specified range of the pantograph head, the free end of the limiting insulating plate is higher than the fixed bow angle by a limited height; the triggering mechanism sends out a pantograph normal working signal; when the contact net line slides out of the specified range of the pantograph head, the free end of the limiting insulating plate moves downwards under the pressure of the contact net line, and the triggering mechanism sends a pantograph descending signal.
本发明公开了一种具有自我保护功能的电气化公路受电弓弓头及受电弓。所述受电弓弓头包括正极滑板和负极滑板,正极滑板的内端和负极滑板的内端分别安装第二弓角,第二弓角包括固定弓角和与固定弓角并列布置的限位绝缘板,固定弓角的上端与正极滑板或负极滑板的内端固定连接,下端与限位绝缘板铰接,且限位绝缘板与固定弓角之间安装复位弹簧和触发机构,限位绝缘板具有两个工作状态:接触网线在受电弓弓头规定范围内滑动时,限位绝缘板的自由端高出固定弓角一限定高度,触发机构发出受电弓正常工作信号;接触网线滑出受电弓弓头规定范围时,限位绝缘板的自由端受到接触网线压力向下移动,触发机构发出受电弓降弓信号。
