Cable performance testing device and cable performance testing method applying same

Abstract

The invention discloses a cable performance testing device and a cable performance testing method applying the same. The device comprises a control console and clamping mechanisms on two sides, a resistance tester and a pair of high-voltage derivation poles, wherein the high-voltage derivation poles are used for applying testing voltage to two ends of a to-be-tested cable, the resistance tester isused for measuring resistance of the to-be-tested cable, the clamping mechanisms are symmetrically arranged on two sides of the control console, and used for clamping and fixing the two ends of the to-be-tested cable, and a conductive adapter assembly is further arranged between the high-voltage derivation poles and the to-be-tested cable. A mechanical chuck is started while the high-voltage derivation poles are electrified, so as to twist the to-be-tested cable and synchronously perform electrification withstand voltage test and record resistance change value and the torsion times of the to-be-tested cable, higher and more precise evaluation values can be achieved by evaluating the durability of the to-be-tested cable through the correlation of the resistance value change and the torsiontimes, meanwhile, the testing efficiency of performance test can be higher, and the cost and time of testing processes can be further lowered and shortened.

[0002] Before all kinds of cables are pushed to the market, their products are generally tested for their environmental tolerance and mechanical properties, such as the conventional torsion resistance test. At present, in the torsion resistance test of cables, usually Clamping mechanisms such as machine tool consoles and mechanical chucks are used to twist the cable. However, in the current test process, the torsion test device can only measure the torsion performance of the cable to be tested, and cannot perform the withstand voltage test. At present, it is usually treated The cable to be tested is twisted for a fixed number of times, for example, 500 turns, and the sheath damage of the cable to be tested is observed after the fixed number of times, as the first evaluation method of the cable to be tested, and then the cable to be tested is removed from the clamping mechanism. Then carry out a withstand voltage test and dissect the cable to check the integrity of the cable conductor. Because the internal conductor damage of the cable to be tested cannot be observed, the test results of the cable to be tested are inaccurate, and it is impossible to accurately judge the cable to be tested. The internal conductor of the cable is damaged after several turns of twisting. Therefore, it is difficult to evaluate the actual service life of the product. In the actual test process, the cable needs to be subjected to withstand voltage tests and torsion tests many times. The process is very troublesome. and waste a lot of manpower
