Abstract

The invention discloses a cable tensile strength detection device, which comprises a guide rod and a tensile test group slidably connected to the guide rod and used for fixing the test cable, and is arranged on one side of the tensile test group There is a control device for driving the tensile test group to perform a tensile test on the test cable. The tensile test group includes two tensile test blocks, and at least one auxiliary test block is arranged on the two tensile test blocks. , the two tensile test blocks are respectively used to clamp the two ends of the test cable. When in use, a plurality of connectors can be shrunk synchronously through the driving device, and further the tension test block and the auxiliary test block can be connected to each other. Increase or decrease the spacing between them synchronously, so that when the cable is stretched, the offset of the auxiliary test block can be used to intuitively reflect the change data of the stretching amount between the segments of the test cable. When , the detection steps of the cable can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of power transmission cables, in particular to a cable tensile strength detection device. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In order to ensure the operation and life of the cables, not only the cables are required to have excellent The insulation performance of the cable, and considering the thermal performance of the cable, the way of laying and the tensile performance of the cable, the corresponding requirements are put forward for the conductive core, insulation and sheath of the cable. [0003] In order to ensure that the produced cables meet the various indicators, it is necessary to carry out relevant inspections on the cables w...
