摘要： PROBLEM TO BE SOLVED: To allow diagnosis of corrosion of a copper stranded wire without being affected by ultrasonic coupling efficiency.SOLUTION: A diagnostic device 10 includes: an ultrasonic probe 2 which makes an ultrasonic wave incident on a copper stranded wire and receives a reflected wave of the incident ultrasonic wave; a determination value calculating unit which calculates a determination value not including the coupling efficiency of the copper stranded wire on the basis of the intensity of back scattering component being a reflected wave of the ultrasonic wave from a region of the copper stranded wire, to which the distance from the ultrasonic probe 2 is within a prescribed range, and the intensity of the reflected wave of the ultrasonic wave from a target region where the degree of corrosion should be determined; and a determination unit which determines the degree of corrosion of the copper stranded wire on the basis of the determination value calculated by the determination value calculating unit.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic probe capable of diagnosing easily a steel stranded wire. SOLUTION: A groove 20A is formed so that suspension wires 100 are fitted thereto, along a propagation direction of an ultrasonic wave, on a transmission/reception surface for an ultrasonic wave on the probe 1. Hereby, a contact area between the probe 1 and the suspension wires 100 is increased, and coupling efficiency is improved, to thereby improve accuracy for detecting an ultrasonic wave reflected by a corrosion part or the like of the suspension wires 100. Further, since the groove 20A is fitted to the suspension wires 100 when diagnosing the suspension wires 100, a center line between the probe 1 and the suspension wires 100 is hardly deviated, and measurement dispersion can be reduced. Thus, suspension wire diagnosis dispensing with dismantlement of a cable terminal becomes possible by utilizing the ultrasonic wave. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：提供能够容易地诊断钢绞线的超声波探头。解决方案：沿着超声波的传播方向，在探针1上的超声波的发送/接收表面上形成有用于将悬挂线100安装到其上的槽20A。因此，探针1和悬挂线100增加，耦合效率提高，从而提高了检测由悬挂线100的腐蚀部分等反射的超声波的精度。此外，由于槽20A装配到悬架线100在诊断悬挂线100时，探针1和悬挂线100之间的中心线几乎不偏离，并且可以降低测量分散。因此，通过利用超声波，能够拆卸电缆终端的吊线诊断成为可能。版权所有（C）2011，JPO＆INPIT
