Abstract

The invention provides a support device. The device comprises a support pipe of a wire and connecting devices; the support pipe of the wire is used for arranged outside the wire in a sleeving mode and supporting the wire; and the connecting devices are connected with the support pipe, and insulator strings can be connected to the upper portions of the connecting devices. Compared with the prior art, the support device has the advantages that due to the fact that the wire is wrapped by the support pipe, the wire cannot be in the shape similar to W, the purpose of constraining the shape of the wire is achieved, the electrical distance between the wire and a pole tower is guaranteed, and then the electricity transmission safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power transmission and transformation, in particular to a supporting device. Background technique [0002] The conductive device connecting the tension clamps of the conductors on both sides of the tension tower is called an overhead transmission line jumper. The jumper string is used to ensure sufficient electrical distance between the charged wire and the conductive part of the tower. [0003] At present, for low-voltage levels, such as 110kV transmission lines, many jumpers are single wires, and the jumper strings are directly pulled up by a structure similar to an I-shaped suspension string. Due to the difference in the operating level of the construction personnel, after construction, the shape of some jumpers is similar to a W shape, which cannot guarantee the electrical distance between the jumper and the tower, thereby affecting the safety of power transmission. Contents of the invention [00...
