Problems solved by technology

In the actual application process, some tension clamps are caused by wire galloping or other extreme weather failure or breakage. This type of tension clamp fracture causes the load applied to the backup clamp to be an impact load. Cord clips do a lot of damage

Embodiment 1

[0033] The standard parts used in the present invention can be purchased from the market, and the special-shaped parts can be customized according to the actual needs according to the instructions and drawings. The specific connection methods of each part adopt mature bolts and rivets in the prior art. , Welding, pasting and other conventional means will not be described in detail here.

[0034] The purpose of the present invention is to provide an experimental device for testing the effectiveness of the line backup clamp. The experimental device is simple in structure, can simulate the impact load that the line backup clamp may receive in actual use, and test the effectiveness of the line backup clamp. and improve the carrying capacity of transmission lines.

[0035] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawi...

Embodiment 2

[0043] Such as Figure 4 As shown, an experimental method for testing the effectiveness of line backup clips is applied to an experimental device for testing the effectiveness of line backup clips, and specifically includes the following steps:

[0044] The first step: install the device;

[0045] Step 2: Set the failure load;

[0046] The third step: apply the load;

[0047] Step 4: the value of the force sensor 10 reaches the failure load;

[0048] Step 5: Disconnect the electromagnetic chuck 2;

[0049] Step 6: Judging the state of the backup clamp 8, if it fails, it is judged as unqualified, and if it does not fail, it is judged as qualified.

[0050] In the specific implementation, the installation device refers to the experimental device for installing and testing the effectiveness of the backup line clamp of the test line. During installation, the square connector 5 is adjusted according to the type of the backup line clamp to be tested and the backup line clamp of ...

Abstract

The invention provides an experimental device and an experimental method for testing the effectiveness of a line backup wire clamp. The experimental device comprises a reaction wall, an electromagnetic chuck, a circular connecting piece, a strain clamp, a square connecting piece, a U-shaped hanging ring, a connecting rod, a backup clamp, a wire, a force sensor, a connecting chain, a pulley, a gravity box, a bottom plate, a first strain gauge, a second strain gauge and a single chip microcomputer. According to the experimental method, connection and disconnection of the electromagnetic chuck and the circular connecting piece are controlled through the single-chip microcomputer, the impact load borne by the line backup wire clamp in reality after the strain clamp fails is simulated, the performance and effectiveness of the line backup wire clamp are comprehensively tested, it is guaranteed that the line backup wire clamp put into application is qualified, line breaking accidents are reduced, and the overall bearing capacity of the power transmission line is improved.

Description

technical field [0001] The invention relates to the technical field of important cross-span overhead transmission lines, in particular to an experimental device and an experimental method for testing the effectiveness of line backup clips. Background technique [0002] Important crossing and crossing lines are overhead power transmission lines that span high-speed railways, expressways, first-class highways, first- and second-level navigable rivers, and important overhead transmission lines. If an important crossing and crossing line occurs, a disconnection accident may cause serious damage to the crossed area. More serious consequences may even cause casualties or major economic losses. [0003] When erecting conductors, the traditional compression strain clamps used at the connection between conductors and pole towers are likely to damage the conductors or cause fatigue, broken strands or even fracture accidents, which seriously affect the service life of overhead lines an...
