Problems solved by technology
If the natural exposure aging test is adopted, the rising and setting of the sun due to the rotation of the earth makes the sunlight fully and relatively uniformly irradiate the surface of the sample from all angles, but if the artificial light aging test is adopted, the test chamber Both the light source and the sample holder are fixed, so the sample cannot receive uniform irradiation, resulting in different performance attenuation of the light-receiving surface and the backlight surface of the composite mandrel after aging by artificial light, which affects Reliability of test results

Embodiment Construction
[0021] refer to figure 1 , the present invention is used for the test device of composite material mandrel light aging test, comprises box body 4 and box cover 3, and described box cover 3 is provided with lamp tube 1, and described box body 4 is provided with sample rack 5, the sample rack 5 includes a motor 6 arranged on a rack body 30, a transmission mechanism, and a plurality of sample clamping and rotating mechanisms 31 arranged side by side. The test frame 5 can be integrated into the light aging test machine and fixed on the inner wall of the box body 4 . The number of sample clamping and rotating mechanisms 31 included in the test rack 5 can be freely increased or decreased according to the size of the box body 4, that is, the number of samples 2 can be changed flexibly. When carrying out the test, it is only necessary to clamp the sample 2 on the two ends of the test frame 5, and close the case cover 3 to open the testing machine for the light aging test.

The invention discloses a testing device for a composite core rod illumination ageing test, which comprises a box body and a box cover and is characterized in that lamp tubes are arranged in the box cover; a test sample holder is arranged in the box body; the test sample holder comprises a motor, a transmission mechanism and one or a plurality of side-by-side test sample clamping and rotating mechanisms, which are all arranged on a holder body; each test sample clamping and rotating mechanism comprises a pair of test sample clamping mechanisms arranged at both left and right sides of the box body and a straight gear; and each test sample clamping mechanism comprises a sealed cover, a rubber plug and a center shaft. Due to the adoption of the testing device, composite core rod test samplescan be conveniently clamped and rotated; and when being irradiated, the test samples are rotated, so that the circumferential directions of the test samples can be irradiated under the condition of uniform and controllable irradiation and the performances of the test samples are ensured to be uniformly attenuated in the process of the illumination ageing test, and thus, the simulated conditions are closer to the actual conditions and the reliability of the test is improved. Moreover, the testing device has simple, convenient and controllable structure.
Description
technical field [0001] The invention relates to the testing field of wires used for power transmission lines, in particular to a testing device for composite material core rods, in particular to a testing device for composite material core rod light aging tests. Background technique [0002] Conductors for transmission lines generally consist of aluminum wires for conducting electricity and core wires for bearing tension. With the continuous improvement of power grid transmission capacity, continuous improvement of material technology and increasingly urgent demand for energy saving and emission reduction, wire manufacturers at home and abroad have introduced a new type of wire that uses composite material mandrels to replace traditional steel cores. This kind of wire has a series of advantages of light weight, high strength, small thermal expansion coefficient, large carrying capacity, and good corrosion resistance. It can be widely used in large-capacity, large drop, and h...
