Description
Technical Field
The utility model relates to an electric power fitting technical field, concretely relates to wire conductor spacer.
Background
With the rapid development of the power industry, a large number of overhead transmission lines are built, the power transmission capacity and the transmission distance are rapidly increased, and large-capacity and long-distance transmission lines are continuously put into operation, so that the safe operation of the lines becomes more and more important. In an overhead transmission line, a wire is a carrier of electric power of the transmission line and is an important component for ensuring the safe operation of a power system. Since the wire is exposed to the open air for a long time, it is easily affected by natural conditions such as wind, rain, ice, snow, and lightning, and other external conditions, and various accidents are easily caused. Among them, the accidents caused by wind vibration are the most. Under the action of wind, the wire is in a vibration state at all times, and the vibration of the wire can be roughly divided into three types according to the difference of frequency and amplitude, namely high-frequency micro-amplitude breeze vibration, medium-frequency middle-amplitude sub-span vibration and low-frequency large-amplitude waving. Among the three types of vibration, the breeze vibration of the wire occurs most frequently, so that the research on the breeze vibration and the finding of corresponding vibration-proof measures have attracted general attention of scientific and technical workers at home and abroad.
The primary purpose of the spacer for split conductors is to limit the relative movement between the conductors and to maintain the split conductor geometry under normal operating conditions. In order to ensure that the distance between the split conductor wire harnesses is kept unchanged to meet the electrical performance, reduce the surface potential gradient and ensure that the conductor wire harnesses cannot generate electromagnetic force under the condition of short circuit to cause mutual attraction collision or even though instant attraction collision is caused, the conductor wire harnesses can be restored to a normal state after the accident is eliminated, therefore, the spacing rods are arranged in the span at certain intervals, and the arrangement of the spacing rods can also play a certain role in inhibiting the oscillation and breeze vibration of the sub-span, but the vibration inhibiting effect of the existing spacing rods still needs to be improved.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Example (b):
referring to fig. 1, the conductor spacer according to the present embodiment includes a damper connecting member 1, a damper 2, a clip arm 3, and a clip 4.
In the present embodiment, the damper connecting member 1 is a regular hexagon, that is, the conductor spacer provided in the present embodiment is a six-bundle conductor spacer. Correspondingly, six dampers 2 are fixedly arranged in the side surface of the damper connecting piece 1 in a welding mode respectively, a wire clamp supporting arm 3 is also fixedly arranged at one end of the damper 2 far away from the damper connecting piece 1 in a welding mode, and a wire clamp 4 is fixedly arranged in the wire clamp supporting arm 3; that is to say, six fastener 4 are the interval separately set up, can guarantee the interval of six split conductors, simultaneously through being provided with attenuator 2, under earthquake or great wind load condition, the power consumption ability reinforce reduces the vibration of wire, reduces the emergence of electric power accident.
Specifically, as shown in fig. 2, the damper 2 includes a first cylinder 21, a second cylinder 22, and a piston rod 23; one end of the piston rod 23 is installed in the first cylinder 21, the first cylinder 21 is filled with hydraulic oil 24 to form a damping oil tank, and the joint of the piston rod 23 and the first cylinder 21 adopts a rubber ring to ensure that the viscous hydraulic oil cannot leak; the other end of the piston rod 23 is installed in the second cylinder 22 and an elastic connection 25 is arranged between the other end of the piston rod and the inner wall of the bottom end of the second cylinder 22. That is to say, the elastic connecting member 25 is installed in the second cylinder 22, and the inner wall of the second cylinder 22 can play a role in fixing the annular deformation of the elastic connecting member 25, so as to increase the critical pressure that the elastic connecting member 25 can bear when being pressed. During normal operation, the damper 2 can perform double-index (namely damping oil tank and elastic connecting piece) parameter self-adaptive balanced consumption on uncertain weak power action which occurs immediately, when oscillation or vibration occurs, the mounting ends of the first cylinder 21 and the second cylinder 22 (namely the parts connected with the damper connecting piece 1 and the wire clamp support arm 3) generate relative displacement and relative speed excited by random pulses, the relative speed pulses are consumed in a balanced manner by viscous damping force between hydraulic oil 24 and a piston rod 23 related to speed index control, and the relative displacement pulses are dissipated in a balanced manner by a variable-stiffness self-adaptive elastic device between the piston rod 23 and the elastic connecting piece 25 related to displacement index control. In particular, the elastic connection 25 is a variable rate spring, i.e. the entire damper combines the hydraulic damping and spring damping characteristics, with an increased energy consumption and efficiency
Specifically, as shown in fig. 3 to 4, the wire clamp 4 is composed of two holding claws 41, and the two holding claws 41 are respectively disposed on two opposite sides of the clamp arm 3 and are fixed by bolts 5. That is to say, the wire clamp 4 is detachably installed, and the clamping claws 41 with different structural shapes can be replaced according to different wires, so that different wire separation requirements are met, and the wire clamp has wide applicability.
