Embodiment
[0017] Example: see figure 1 — figure 2 , in the figure, 1-Arc adjustment plate; 2-Right-angle hanging plate; 3-Triangular plate; 4-U-ring; Tension protection wire clamp; 8- overhead wire; 9- U-ring; 10- connecting rod; 11- crimping wire clamp.
[0018] The technical scheme of the method and device for double-connection and double-protection in the important spanning area of an overhead wire is: it includes a crimping wire clamp 11, wherein: one end of the crimping wire clamp 11 is connected with the overhead wire 8, and the other end is adjusted by a U-shaped ring and an arc. One end of the plate 1 is connected, the other end of the arc-shaped adjustment plate 1 is connected with one end of the connecting rod 10 through the U-shaped ring 9, and the tension protection wire clamp 7 is arranged on the overhead wire 8, and the tension protection wire clamp 7 passes through. The two tensile protective wire clip structural frames 6 are respectively connected with one end of th...

The invention discloses a duplex double-protection method and device for important crossing regions of an overhead conductor. The duplex double-protection device comprises a crimping wire clamp, and is characterized in that one end of the crimping wire clamp is connected with the overhead conductor, the other end of the crimping wire clamp is connected with one end of an arc-shaped adjusting plate through a U-shaped ring, the other end of the arc-shaped adjusting plate is connected with one end of a connecting rod through a U-shaped ring, the overhead conductor is provided with a tension protection wire clamp chuck, the tension protection wire clamp chuck is connected with one ends of two tension protection wire clamp connecting rods respectively through two tension protection wire clamp structural frames, the other ends of the two tension protection wire clamp connecting rods are hinged with base angles of a triangular plate, a vertex angle of the triangular plate is connected with the arc-shaped adjusting plate through a right-angle hanging plate, and duplex double-protection for the connecting rod is formed. According to the invention, the backup tension protection wire clamp chuck acts immediately after the primary load-bearing wire clamp is damaged, the backup tension protection wire clamp chuck converts from slight load bearing into bearing for all tensile forces of the overhead conductor, and the rated pulling strength of various feasible backup tension protection wire clamp chucks can meet an instantaneous impact force generated by various types of overhead conductors.
Description
Technical field: [0001] The invention relates to a method for safely crossing overhead wires, in particular to a method and a device for double-connection and double-protection in important crossing areas of overhead wires. Background technique: [0002] With the rapid development of the power grid and the drastic changes in the social environment, the operation and maintenance management of high-voltage transmission lines presents the characteristics of diversification and complexity. , highways, houses, schools and other important areas, once the overhead line falls off and disconnection accident in the important crossing area, it will cause huge loss of personnel and property, and cause extremely bad social impact. [0003] Currently used overhead ground wire and wire connection gold include hydraulic wire clamps, bolt-type wire clamps, and pre-twisted wire clamps. On the one hand, the transmission lines at important crossovers cannot be double-connected and protected by...
