Study on the Applicable Frequency of Ultrasonic Phased Array Detection Probe for Tension Clamp

In recent years,the demand for electric power&energy is increasing,so higher requirements for the security and stability of power grid components are put forward in China.Tension clamp is a kind of hardware that bears the tension of the wire or lightning protection wire,whose structural security is related to the security operation of the whole power grid.For this reason,this paper explores the applicable frequency of ultrasonic phased array probes in the crimping quality detection of tension clamps with the combination of simulation and experiment,to achieve the purpose of improving resolution and accuracy of the detection.
