Abstract In order to study the application of electromagnetic pulse welding technology in the field of power cable joint welding, this paper designed a set of electromagnetic pulse welding device that can be used for welding different types of cable joints. The device included high-current pulse generator, welding coil and system control module. The high-current pulse generator consisted of six parallel pulse generation modules. Each module included four parallel capacitors and one triggered vacuum switch. According to different welding requirements, the voltage and quantity of the module can be adjusted to output current pulses of different parameters. In addition, to reduce the effect of loop spurious parameters on the pulse current peak and improve the welding effect, a low-impedance coaxial cable and a welding coil with a collector function were designed. Combining the theoretical and simulation calculations of the structure and parameters of the welding device, a prototype of the electromagnetic pulse welding device was finally developed. After testing, the device has a working voltage of 15 kV and a peak current of 600 kA, and can successfully complete the welding of the cable joint.

Key words： Electromagnetic pulse welding cable connectors triggered vacuum switches coaxial cables welding coil
