Description

Technical Field

[0001] The invention belongs to the technical field of cable connection of power distribution lines, and in particular relates to a disconnection quick connection device for power distribution lines. Background Art

[0002] Distribution lines are power lines that are responsible for distributing electric energy in the power grid, and they directly transmit electricity to the user end. According to different voltage levels, distribution lines can be divided into different types: high-voltage distribution lines: voltage range is 3.6kV~40.5kV. Low-voltage distribution lines: voltage does not exceed 1kV, frequency does not exceed 1000Hz, and DC does not exceed 1500V. Distribution lines can be divided into two categories according to their structure: overhead lines and cable lines; overhead lines: composed of conductors, insulators, lightning conductors, poles, foundations, guy wires, crossarms, hardware, grounding devices, etc. Cable lines: mainly include cable bodies, cable line structures, cable joints, etc. When the distribution line is working normally, lightning strikes, strong winds breaking branches and falling on the line, or throwing metal objects on the guide line will cause the distribution line to break. When a line is broken, the line needs to be repaired and connected.

[0003] At present, when repairing a broken line, it is generally done by crimping with crimping pliers or crimping with a connecting tube, but the repair time is relatively long; some use quick-connect devices for repair, such as the patent with publication number CN207053063U, which discloses a quick-connect device for broken overhead insulated distribution lines. During the tightening process, the device rotates the transmission shaft to achieve the opposite movement of the first traction hook and the second traction hook, and then simultaneously moves the two broken wires at the broken point in the direction close to the housing, realizing bidirectional tightening, and can achieve quick connection of the broken wire by quick tightening. However, the quick-connect device for broken overhead insulated distribution lines does not have a self-locking function when in use. When the two ends of the broken wire are pulled by two traction hooks, the wire rope where the traction hook is located and the broken wire are both in a straight state. At this time, it is necessary to fix the rotating wrench by other means to quickly connect the broken wire, which has certain limitations. Summary of the invention
