[0002] The overhead contact line busbar is an important component of the rigid overhead contact line, primarily used to clamp and fix the contact wire, and to carry and transmit electrical energy. The testing of overhead contact line busbars must adhere to strict standards to ensure the safe and stable operation of the railway power supply system. Among the many testing items for overhead contact line busbars, the clamping performance test is as follows: A horizontal tension perpendicular to the conductor direction is applied to one side of the dovetail groove of the busbar, causing a displacement of 2.5 mm, then unloaded. This process is repeated until the required number of tests are reached. The sample should not show cracks or plastic deformation. Currently, the busbar clamping opening test is conducted manually. Manually applying the load to one side of the dovetail groove of the busbar is prone to deviations in magnitude and direction, and the amount of displacement is difficult to control accurately, thus affecting the accuracy of the test results.
