Problems solved by technology
[0002] For ultra-high voltage transmission lines of 220KV and above, in order to transmit power over long distances and reduce line reactance, each phase conductor uses more than 2 to 4 split conductors, and the arrangement is various, and the spacing and sag of the sub-conductors of the same phase are required to be the same Yes, due to the difference in construction, installation and operation, the spacing and sag of the sub-conductors will change, which will affect the normal operation of the transmission line. In the past, tools such as zipper hoists were used to adjust the sag. The method is complicated and there are many operators. The use of tools is heavy, the construction is difficult, and the labor intensity increases

Embodiment Construction
[0009] Examples, see attached figure 1 , The sag adjustment tool for the split conductors of the transmission line is that a tensioner boss 11-1 is provided on the left end of a horizontal side of the triangular tensioner 11, and the tensioner boss 11-1 passes through the clamping boss 1-1 Use the positioning pin 12 to connect the wire clamping body 1. In the middle of the wire tensioner 11, there is an arc chute 11-2 under the wire clamping body 1, and a sliding pin 2 is used in the chute 11-2. Connect the card line body 1. An arc-shaped chute 2 11-3 is provided at a long oblique side of the tensioner 11, and the connecting pin 5 is used in the chute 2 11-3 to be movably connected to the adjusting plate 6, and the long oblique side of the tensioner 11 Two spring seats 3 are fixed at the middle of the side, a return spring 4 is installed between the two spring seats 3, and a spring cover 10 is provided on the return spring 4. Connect the left end of the labor-saving screw 7 w...

The invention belongs to power transmission and transformation tools in the electric power industry, and particularly relates to a power transmission line bundled connector sag adjustment tool. The power transmission line bundled connector sag adjustment tool comprises a wire grip (11), a positioning pin (12), a connecting hinge pin (5), an adjustment plate (6), a labor saving lead screw (7), a ratchet wheel spanner (8) and a connecting plate (9). A wire grip boss (11-1) is arranged on a horizontal edge of the triangular wire grip (11) and connected with a wire clamping body (1) by means of the positioning pin (12) and through a wire clamping boss (1-1). An arc-shaped first sliding groove (11-2) is formed in the wire grip (11). An arc-shaped second sliding groove (11-3) is formed in the long inclined edge of the wire grip (11) and is movably connected with the adjustment plate through the connecting hinge pin (5). A reset spring (4) is arranged in the middle of the long inclined edge of the wire grip (11) through a spring base (3). A spring cover (10) is arranged on the upper face of the reset spring (4). The power transmission line bundled connector sag adjustment tool is light in weight and convenient to use, the construction difficulty is lowered, the number of operators is lowered, and operation is safe and reliable.
Description
Technical field [0001] The invention belongs to a power transmission and transformation construction tool in the power industry, and particularly relates to a sag adjustment tool for a split conductor of a power transmission line. Background technique [0002] For ultra-high voltage transmission lines of 220KV and above, in order to transmit power over long distances and reduce the line reactance, each phase conductor adopts 2~4 or more split conductors, and the arrangement methods are various, and the spacing and sag of the in-phase sub-conductors are required to be the same Yes, due to the difference in construction, installation and operation changes, the spacing and sag of the sub-conductors have changed, which affects the normal operation of the transmission line. In the past, the sag was adjusted using tools such as zipper hoists. The method was complicated and there were many operators. The tools are cumbersome, the construction is difficult, and the labor intensity increa...
