Background technique

Power distribution is a link in the power system that is directly connected to users and distributes electric energy to users. The power distribution system is composed of distribution substations, high-voltage distribution lines, distribution transformers, low-voltage distribution lines and corresponding control and protection equipment. In the process of power distribution, a line transfer device is required to transfer the wires. However, the existing transfer device has a poor fixation effect on the wires, which leads to the instability of the wires during the transfer process. In addition, the wires are easy to fall off during the transfer process, so that the normal use of the transfer joint cannot be guaranteed, which has brought certain adverse effects to the actual use, so it needs to be improved. The application number is to disclose a line transfer device, which consists of two distribution line bodies, copper wires and connecting plates. The inner walls of the two distribution line bodies are fixed with copper wires, and the surface of the distribution line body is movably connected with connecting plates. Both sides of the connecting plate are fixedly connected with U-shaped frames. The inside of the U-shaped frame is slidingly inserted with two limit blocks. The side walls of the two limit blocks are fixedly connected with groove plates. The fixing part is a cone thorn, which solves the problem that if the copper wires on the two distribution lines are directly entangled together, the two distribution lines are easy to fall off under the condition of straightening and stress. However, the thorn awl provided in the grooved plate of this scheme is easy to pierce the cable skin and cause damage.

In this regard, a new power distribution line switching device is developed to replace the existing switching device, and to solve the problem that the wires are easy to fall off during the switching process.
