The invention provides a spacing rod vibration test device. The spacing rod vibration test device comprises a first supporting rod, a second supporting rod, a base, a vibration device, a first cross beam and a first clamping device, wherein the first supporting rod and the second supporting rod are arranged on the base, and both ends of the first cross beam are connected with the first supporting rod and the second supporting rod separately; the first clamping device is connected with the first cross beam in a rotatable manner, the first clamping device is fixedly connected with the first cross beam by means of a first fastener, and the first clamping device is used for clamping a spacing rod; and the vibration device is connected with the base, and is used for being in contact connection with the spacing rod and providing vibration for the spacing rod. The spacing rod vibration test device provided by the invention can fix the spacing rod in the height direction of the test device by means of the first clamping device, so as to complete IEC-standard aeolian vibration fatigue detection and subspan oscillation fatigue detection on the spacing rod, further can learn about vibration resistance of the spacing rod before the spacing rod is installed, and ensures the safety of a power transmission line.
Description
technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a spacer bar vibration test device. Background technique [0002] At present, since the reform and opening up, my country's electric power industry has developed rapidly. Especially in recent years, with the continuous high-speed growth of electricity demand, the speed of electric power development has been further accelerated. [0003] The main purpose of spacer bars for split conductors of power transmission lines is to limit the relative movement between the sub-conductors and maintain the geometry of the split conductors under normal operating conditions. Two, four or more split conductors are used for each phase conductor of long-distance and large-capacity EHV transmission lines. For example, 220kV and 330kV transmission lines use two-split conductors, 500kV transmission lines use three-split or four-split conductors, and ultra-high voltage t...
