Development of an Ultrasonic Testing System for Press Connectors of Railway Catenary Wires
Abstract
This paper describes the development of an ultrasonic testing system for press connectors of railway catenary wires. With this system it is possible for the first time to detect the formation of cracks at an early stage. By means of a test gripper which is adapted to the hexagonal cross section of the press connector, several ultrasonic probes are pressed onto the crimped surfaces. With an appropriate wedge the ultrasound waves are guided to the inner cracks in order to generate echo signals in reflection and to ensure a stable coupling control. During inspection of new and existing installations, potentially damaged press connectors can be quickly detected and replaced if necessary. The system is based on IKTS’ proprietary PCUS® pro electronics and has been successfully evaluated in first field tests. The prototype consists of six ultrasonic probes integrated into the gripping pliers so that a complete compression joint can be tested without rotating the gripper.
