High-voltage direct-current cable joint detection method, device and system

The invention provides a high-voltage direct-current cable joint detection method, device and system. The method comprises the following steps: obtaining test data of a high-voltage direct-current cable joint to be detected; based on a preset adversarial network model and the test data, determining a cracking degree detection result of the to-be-detected high-voltage direct-current cable joint; the preset adversarial network model is obtained by pre-training based on historical test data of batch high-voltage direct-current cable joint samples and actual cracking degree detection results corresponding to the samples, and each high-voltage direct-current cable joint sample corresponds to historical test data under multiple temperature conditions. The detection accuracy and efficiency of the cracking degree of the high-voltage direct-current cable joint can be improved, and then the operation safety of the high-voltage direct-current cable can be improved. 本申请提供了一种高压直流电缆接头检测方法、装置及系统，该方法包括：获取待测高压直流电缆接头的测试数据；基于预设
