Single-bundle conductor tension backup complete device

Abstract

The invention relates to a single-bundle conductor tension backup complete device which is composed of a backup tension device, an extension pull rod, a wire protecting strip, a supporting wire clamp,a wire pulling device, a U-shaped ring, a tensioning device, a parallel hanging plate and a connecting plate. The wedge-shaped backup tension device has a large gripping force on a conductor, is convenient to install, and tensions the conductor tighter and tighter in the using process. The outer surface of the backup tension device is designed into an arc structure, so that the stress concentration is effectively prevented, and the structure is reliable. With the arrangement of an extension pull rod, a rigid connecting corner is formed by a back-up tension hanging plate and a stay wire device, and the connection of the whole device is more reliable. Due to the adoption of a support wire clamp, the galloping between the complete set of backup device and the wire is avoided, and the servicelife of the wire is greatly prolonged. The whole set of device can share the tension for the original compression type tension, so that the service life of the original compression type tension is prolonged. With the reasonable structure, great practical and promotional values are achieved.

Description

technical field [0001] The invention relates to a safety protection device for power transmission and distribution lines in the electric power industry, in particular to a complete set of tension-resistant backup devices for single-split conductors. Background technique [0002] After retrieving the relevant patent documents, no single-split wire tension backup complete set with the same structure as the present invention has been retrieved. At present, some transmission line conductors use compression type strain clamps, but the actual construction process is affected by the construction conditions and the construction personnel's technology, the quality of the crimped conductors is difficult to control, and it cannot be monitored by monitoring means on site.

Problems solved by technology

At present, some transmission line conductors use compression type strain clamps, but the actual construction process is affected by the construction conditions and the construction personnel's technology, the quality of the crimped conductors is difficult to control, and it cannot be monitored by monitoring means on site. However, as the application time becomes longer, the crimping part of the clamp will break and easily cause a major electric shock accident. The existing method of preventing wire breakage is to wind the pre-twisted wire at the connection part, which increases the weight of the line and causes damage to the tower. Therefore, it is necessary to design a backup device to prevent the failure of compression-type tension, which can ensure the safe and reliable operation of the power grid, avoid accidents caused by wire drop, and gain valuable time for emergency repairs to meet the development needs of modern power grids.
