| 目的 探究磁脉冲技术在铜线夹与钢芯铝绞线(ACSR)电缆线束压接接头中的应用，以及放电能量对电缆接头性能的影响。方法 利用磁脉冲放电设备在40 kJ和45 kJ放电能量下压接Cu-ACSR电缆接头，观察接头宏观形貌，进行接头拉伸试验，观察接头失效情况并评价接头性能。结果 压接的位置越靠近末端，压接区直径的变形量越大。40 kJ放电能量下对应失效后，电缆线束末端发生了较为明显的弹性回复，其外圈铝合金线束张开，而在45 kJ时没有明显张开现象。45 kJ放电能量下对应失效后的铝合金线束延长量明显高于40 kJ时。同时，45 kJ放电能量下压接电缆接头截面可以观察到更大且更均匀的变形。结论 使用磁脉冲技术可以实现异种材料的铜线夹和ACSR电缆线束的有效连接。在45 kJ放电能量下压接电缆接头的最大拉伸载荷相对于40 kJ时提升了55%，由此说明在45 kJ放电能量下压接电缆接头性能优于40 kJ时。 |

| This paper aims to explore the application of magnetic pulse technology on the crimping joints between copper clamp and aluminum cable steel reinforced (ACSR) cable harness, and analyze the effect of discharge energy on the performance of cable joints. The magnetic pulse discharge equipment was used to crimp Cu-ACSR cable joints at 40 kJ and 45 kJ discharge energies, and the macroscopic morphology of the joints was observed. The tensile test was carried out to observe the joint failure and evaluate the joint performance. The test results showed that the closer the crimping position was to the end, the greater the deformation of the crimping zone diameter was. The end of the cable harness had obvious elastic recovery after the failure at the discharge energy of 40 kJ. The aluminum alloy harness of the outer ring opened, but there was no obvious opening phenomenon at 45 kJ. The extension of the aluminum alloy harness at 45 kJ discharge energy after failure was significantly higher than that at 40 kJ. Simultaneously, larger and more uniform deformation could be observed in the cross section of crimped cable joint at 45 kJ discharge energy. Consequently, the use of magnetic pulse technology enabled the efficient connection of copper clip and ASCR cable harness of heterogeneous materials. The maximum tensile load of the crimping cable joint at 45 kJ discharge energy was increased by 55% compared with that at 40 kJ, which indicated that the crimping cable joint performance at 45 kJ discharge energy was better. |
