[0003] The publication number is CN111082283A, which provides an auxiliary tensile device for high-voltage cable docking. Due to the high-voltage cable has a certain weight, it will generate a relatively large tensile force, and the tensile device is used to clamp the two parts of the cable. The relative position between them is fixed, so it cannot be adapted to insert new cables of different lengths when in use

The invention provides an auxiliary device for a butt joint of an open circuit cable in a charged state, and the device comprises two support frames, a connecting rod, a hoop assembly, a large gear, arotating shaft, a rack, a connecting shaft, a telescopic rod assembly, a small gear and a turntable, wherein the two support frames are in butt joint through the connecting rod, the hoop assembly isarranged at the bottoms of the support frames, and the large gear is arranged on the connecting rod through the rotating shaft; the two racks are connected with the two supporting frames respectivelyand meshed with the large gear respectively, the connecting shaft is sleeved with the rotating shaft, the telescopic rod assembly is arranged on the connecting rod, one end of the telescopic rod assembly makes contact with the end face of the large gear, and the small gear at the end of the telescopic rod assembly is meshed with the small gear at the end of the connecting shaft. The large gear isrotated to drive the two racks to move in the direction close to each other or away from each other, so that the hoop assembly can clamp two electric wires with different spans, reverse pull force generated between the electric wires and the hoop can drive the two supporting frames to move in the direction away from each other, and then the telescopic rod assembly can lock the electric wires.
Description
technical field [0001] The invention relates to the technical field of power grid connection, in particular to an auxiliary device for disconnecting cables in a charged state. Background technique [0002] When the wire is used for a long time, it will be disconnected due to tension or external force. After the wire is disconnected, the current cannot pass through and an open circuit is formed. Then the wire at the break needs to be replaced again. The conventional replacement method is: Cut off the wire at the broken part, and then reconnect a wire at the gap, then the cut wire is divided into two sections during the wiring process, and the wires have a force in the direction away from each other, so you need to use auxiliary tools Fasten the two lengths of wires for wiring. [0003] The publication number is CN111082283A, which provides an auxiliary tensile device for high-voltage cable docking. Due to the high-voltage cable has a certain weight, it will generate a relati...
