Abstract

The present invention provides a cable test device. The cable test device comprises a fixing table and a pressing mechanism which is fixedly mounted on a base or the fixing table; the upper end surface of the fixing table is provided with a plurality of clamping portions which are distributed in a right-left direction; the upper end surfaces of the clamping portions are provided with cable clamping grooves which are communicated in a front-back direction; the pressing mechanism includes a pressing plate opposed to the clamping portions; an end surface of the pressing plate, which faces the clamping portions, is provided with an elastic insulating layer; and the pressing mechanism can drive the pressing plate to move linearly in a perpendicular direction. With the cable test device adopted, operation is simple and quick in a testing experiment process, so that operating efficiency is improved; a cable can be fixed reliably and firmly; a false test rate can be decreased; the safety of a testing experiment can be improved; local resources are not required to support a cable in the testing experiment, and therefore, dependence of a test process on a field environment can be decreased.

Description

technical field [0001] The invention relates to the field of cable testing tooling, in particular to a device for supporting and fixing high-voltage cables when testing high-voltage cables. Background technique [0002] A cable is usually a rope-like wire twisted by several wires or groups of wires, each group of wires is insulated from each other, and is often twisted around a center, and the entire outside is covered with a highly insulating covering. [0003] Cables are mostly erected in the air or buried underground or underwater to complete telecommunications or power transmission, so the on-off of cables is directly related to the safe and stable operation of the entire power grid and communication system. In view of the importance of cable on-off for power transmission and communication and the complexity of cable erection or embedding work, it is necessary to conduct multiple tests such as live insulation resistance, conduction resistance and withstand voltage tests ...
