Abstract
The invention provides a cable bending test machine. The machine comprises a control device, a power device, a first rotating wheel with adjustable diameter and a second rotating wheel with adjustablediameter; the first rotating wheel is parallel to the second rotating wheel; the first rotating wheel is used for driving the second rotating wheel to make to make a to-be-detected cable test samplewinding the second rotating wheel wind the first rotating wheel; the power device is electrically connected with the first rotating wheel and the second rotating wheel and used for driving the first rotating wheel and the second rotating wheel to rotate; the control device is used for controlling the power device to drive the first rotating wheel and the second rotating wheel to rotate at a presetspeed and a preset number of turns. By means of the cable bending test machine, the to-be-tested cable test sample sequentially winds the second rotating wheel and the first rotating wheel at the preset speed and the preset number of turns, various performances after the to-be-detected cable test sample is bent are detected, and the detection efficiency is improved.
Description
Technical field [0001] The invention relates to the technical field of electrical measurement and detection, in particular to a cable bending test machine. Background technique [0002] When the cable is laid, the environment is complicated and needs to be bent, and its performance should not be reduced or damaged in the case of bending. Therefore, its bending performance is an important part of the cable type test. For high-voltage and ultra-high voltage cables of 35kV and above, this test is a prerequisite for other type tests. At present, the cable bending test device on the market is mainly for the bending test of low-voltage wires and cables, so as to detect the mechanical performance of the bending in the experiment. However, the test of large medium and low voltage cables mainly relies on manual coiling and bending tests on large cable reels, which is inefficient and dangerous for experimenters. However, the high flexibility and heavy weight of the medium and high volta...
