The invention discloses a pantograph lower guide rod load sensor, a measuring system, a measuring method and a pantograph. The load sensor comprises a sensor body. The sensor main body is provided with N stress surfaces, each stress surface is integrated with a load chip, the N load chips are located on the circumference of the same section, one end of the sensor main body is provided with a stud, the other end of the sensor main body is provided with a stud hole, and N is an even number greater than or equal to 2. The embodiment of the invention provides a pantograph lower guide rod load sensor which can monitor the stress and bending moment of a lower guide rod in real time in the normal current collection working state of a pantograph and judge whether spherical hinges at the two ends of the lower guide rod are clamped or not through the stress and the bending moment.

    一种受电弓下导杆载荷传感器、测量系统、测量方法及受电弓,所述载荷传感器包括传感器主体;所述传感器主体具有N个受力面,每一受力面上集成有载荷芯片,N个载荷芯片位于同一截面圆周,所述传感器主体的一端设有螺柱,所述传感器主体的另一端设有螺柱孔,N为大于等于2的偶数。本发明实施例提供一种受电弓下导杆载荷传感器,能够在受电弓正常受流工作状态下实时监测下导杆应力、弯矩,以及通过应力和弯矩判别下导杆两端球型铰链是否卡滞。
