Drainage wire quick connecting device for strain clamp and use method thereof

Abstract

The invention discloses a drainage wire quick connecting device for a strain clamp and a using method thereof, the drainage wire quick connecting device comprises a clamp body, a lower clamping plate used for clamping a drainage wire is connected below the clamp body, the upper end of a frame body is rotatably connected with symmetrically arranged upper clamping rings through a first rotating shaft, and a cable space for a cable to pass through is reserved between the two upper clamping rings; the frame body is slidably connected with a sliding rod, the upper end of the sliding rod is arranged in the cable space, and the lower end of the sliding rod is rotatably connected with symmetrically-arranged swing rods. The swing rod is connected with the clamp body through the spring and rotationally connected with the clamp body, and the upper end of the swing rod is movably connected with the upper clamp ring. The high-altitude construction problem of drainage wire connection is solved, rapid connection work of the drainage wire and the cable can be achieved without power off, and therefore the accident that the drainage plate of the strain clamp is burnt out is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a quick connection device for drain wires for strain clamps and a method for using the same. Background technique [0002] With the expansion of the grid scale and the continuous improvement of the importance of electric energy to people's life, the society has higher and higher requirements for the reliability of power supply. Transmission lines are an important part of the power system, and its reliability is crucial to the safety of the entire power system Stable operation plays an important role. However, the heating problem of the diversion plate of the strain clamp is an important factor affecting the safe and stable operation of the transmission line. The heating of the diversion plate is caused by the thermal effect of the current. The diversion plate itself has a certain resistance. Increase the temperature of the drain plate. Under normal circumstances, the contact res...

Problems solved by technology

Although this design can divert heat and avoid overheating of the strain clamp drainage plate, it also has the following disadvantages: it still needs manual climbing operation, which is not only time-consuming and laborious, but also has unsafe factors, and even needs a power outage, and it is connected by bolts. For a long time, it is easy to cause the bolts to loosen and the sparks generated by the loose connection to damage the cables and even cause large-scale power outages, causing losses to people's production and life.
