Wire clamp for circuit

Abstract

The invention belongs to the technical field of power supply devices, and relates to a wire clamp for a circuit. The wire clamp at least comprises a group of supporting units, each group of supporting units comprises two triangular elastic connecting assemblies; a first wire winding rod is connected between vertex angles of the two triangular elastic connecting assemblies, and second winding rods are correspondingly connected between the two base angles of each triangular elastic connecting assembly respectively; each group of supporting units can be independently connected to a wire in a line in series, or the multiple groups of supporting units can be connected in series and share one second winding rod in pairs in sequence to form a supporting unit group to be arranged on the wire, and the wire can be wound around one second winding rod of the single group of supporting units and then sequentially wound around the first connecting rod and the other second winding rod of the group of supporting units. According to the wire clamp, the wire in the line can have a telescopic elastic function, when the line is built, more redundant allowance does not need to be reserved for the line, and the requirement for thermal expansion and cold contraction of the wire can be met.

Description

technical field [0001] The invention belongs to the technical field of power supply devices, and in particular relates to a wire clamp for lines. Background technique [0002] Transmission lines and distribution lines are an important part of the power grid, in which they are responsible for the task of transmitting electric energy. When erecting the line, due to the gravity of the wire in the line and considering the phenomenon of thermal expansion and contraction, it is necessary to reserve a certain sag for the line. The size of the sag should not only meet the safety distance of the line to the ground, Also in the winter season, when the wires in the line shrink when they are cold, it is guaranteed that there is a certain margin so as not to snap the wires in the line. [0003] When the line crosses roads, bridges, and buildings, special attention should be paid to the safety distance of the line to the ground. It must not only meet the safety requirements for the groun...

Problems solved by technology

[0003] When the line crosses roads, bridges, and buildings, special attention should be paid to the safety distance of the line to the ground. It must not only meet the safety requirements for the ground, but also leave a certain margin for the line to meet the thermal expansion and contraction of the conductor in the line. Requirements, the usual practice is to heighten the poles across the two ends of the line, which will increase the construction cost and even the construction difficulty of the power company. In view of this, it is urgent to develop an adaptive device for adjusting the sag height of the line to overcome the line construction these difficulties in
