The utility model discloses a busbar arc protection device, which relates to the technical field of electric power equipment and comprises a partition plate, which is arranged at the lower end inside the main body of the busbar arc protection device. The main body of the busbar arc protection device is welded and connected to the partition plate. The device can make the connecting wires wrapped around the outside of the device squeeze the flexible hydraulic tube when being pulled by external force, so that the flexible hydraulic tube is deformed, and then the connecting wires have a certain margin to be stretched, so as to avoid the connecting wires being damaged due to excessive force, and to avoid the insulation performance of the connecting wires being reduced. At the same time, hydraulic oil is arranged inside the flexible hydraulic tube. When the flexible hydraulic tube is deformed, the hydraulic oil is forced to enter the inside of the transmission hydraulic box, wherein the hydraulic oil converts the violent pulling force of the connecting wire into the pressure internal energy of the hydraulic oil, and then absorbs the impact force, so as to prevent the connecting wires from being subjected to excessive force, and make the device more practical.
