Automatic cable swing arm system for power-on test of refrigerating unit

The utility model relates to an automatic cable swing arm system for a power-on test of a refrigerating unit, and the system comprises a support which is fixedly disposed on a wall, and the support is provided with a swing arm in a horizontal rotating manner. A cable conveyor is arranged on the swing arm, and a cable moves in the length direction of the swing arm through the cable conveyor. The swing arm rotates along the support and can drive the cable to complete circular motion around the support, the cable conveyor can drive the cable to do linear motion along the swing arm, and the two motions are combined so that the interface end of the cable can form a fan-shaped motion area. Therefore, no matter the refrigerating unit is arranged at any position of the fan-shaped area, the cable can quickly and accurately move to the position to be connected, so that the cable is prevented from being dragged on the ground, and the use safety and convenience are improved. 本申请涉及一种制冷机组通电测试用电缆自动摆臂系统，包括：固定设置在墙体上的支架，所述支架上水
