High-voltage cable insulation testing device

Abstract

The invention relates to the technical field of cable insulation testing, and discloses a high-voltage cable insulation testing device which comprises a shell, two binding posts arranged on one side of the shell, a crank arranged on the other side of the shell, a bottom plate arranged at the bottom of the shell and a positioning part arranged between the bottom plate and the shell. The adsorption component is arranged at the bottom of the positioning component; the adsorption part is used for increasing the adsorption force between the bottom plate and the table top when the downward pressing assembly is pressed; the positioning part comprises a rotating column arranged at the bottom of the shell, two downward pressing assemblies arranged on the rotating column and positioning assemblies arranged at the bottoms of the downward pressing assemblies. By arranging the positioning part and the adsorption part, the adsorption force of the bottom plate to a table top can be increased, so that the stability of the bottom plate is improved, the situation that the bottom plate and the shell shake cannot occur when a tester rotates a crank for testing, the rotation in any direction can be adjusted, and positioning and fixing after adjustment can be achieved; and the stability, convenience and adaptability of device testing are improved.
