Description

An anti-galling reinforced tension clamp

technical field

The utility model relates to a wire clip for a transmission line, in particular to an anti-galling reinforced tension wire clip used for fixing a steel-cored aluminum stranded wire in an overhead transmission line in a power system.

Background technique

The tension clamp is a metal tool used to fix the wire on the tension tower in the overhead transmission line. Its main body is crimped with the wire and connected in series with the tension insulator to bear all the tension from the wire. The tension-resistant drainage plate is connected with the jumper, which not only acts as a diversion, but also must bear the gravity and tension exerted by the jumper. Ordinary strain clamp drainage plates are mostly made of bent aluminum tubes and then pressed. This structure is easy to process, but the transition between the aluminum tube and the drainage plate is a weak part. If the force on the jumper is uneven or the force changes suddenly It is easy to cause the transition part of the drainage plate to break.

With the change of meteorological conditions in the area of the transmission line, the problem of galloping of the transmission line appears in some areas. The galloping section, especially the galloping section of the resistant line, is more serious. When the tension clamp is galloping, the impact force of the drainage plate from the jumper will be doubled. If it is in a dancing state for a long time, it will inevitably cause the wire-resistant drainage plate to break. This requires the reinforcement of the tension drain plate. Generally, the reinforced strain clamp adopts double drain plates. If the distance between the two plates is too large, the contact between the wire drain clamp and the tension double plate drain clamp will not be tight, which will affect the conduction. flow, and prone to tension heat, if the distance between the two plates is too small, it will be difficult to install the wire drainage plate and the tension double drainage plate during the construction process.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide an anti-galling strengthened strain clamp that can effectively avoid the problem of the breakage of the drainage plate caused by the galloping of the line.

In order to achieve the above purpose, the utility model adopts the following technical solutions: an anti-galling strengthened strain clamp, which is characterized in that it includes a main body of the strain clamp, a steel anchor ring, a drainage plate of the strain clamp, and an aluminum tube of the main body and the drainage clamp, one end of the main body of the tension clamp is crimped with the steel-reinforced aluminum stranded wire, and the other end is crimped with the steel anchor ring; the top of the drain plate of the tension clamp is sleeved on the aluminum tube of the main body and welded integrally therewith, and the bottom of the drain plate of the tension clamp is connected with the drain clamp.

The strain clamp drainage plate is integrally formed by extruding a thickened veneer.

The main body of the strain clamp adopts an I-shaped structure.

Because the utility model adopts the above technical scheme, it has the following advantages: the utility model uses the top of the strain clamp drainage plate to be sleeved on the main aluminum tube and welded into one body with it, and the tension clamp drainage plate is thickened The veneer is extruded into one piece, which not only greatly improves the strength of the tension clamp drainage plate, but also improves the impact resistance, fatigue performance and electrical conductivity of the tension clamp drainage plate, which can effectively prevent the tension clamp drainage plate from The drain plate breaks during operation. The utility model can be widely applied in overhead power transmission lines of electric power systems.
