On-line test device for power cable insulation

Abstract

The invention provides a power cable insulation on-line test device. The power cable insulation on-line test device includes a cable extruder, a cooling device, a power frequency withstand voltage spark test device, a cable traction machine and a cable collecting wheel arranged behind the cable traction machine; the cooling device includes a cooling water tank and a cooling pipeline arranged in the cooling water tank; the cooling water pipeline passes through the cooling water tank; a cooling coil is laid on the inner wall of the cooling pipeline; the inlet of the cooling pipeline is corresponding to the outlet of the cable extruder; the outlet of the cooling pipeline is corresponding to the inlet of the power frequency withstand voltage spark test device; the outlet of the power frequency withstand voltage spark test device is corresponding to the inlet of the cable traction machine; the power frequency withstand voltage spark test device includes a controller; and the controller is connected with a sound and light alarm. The power cable insulation on-line test device has the advantages of scientific design, comprehensive detection, simple operation and reliable production quality.

Description

technical field [0001] The invention relates to a cable insulation test device, in particular to an on-line test device for power cable insulation. Background technique [0002] Due to the limitation of the use environment of the power cable, its insulation performance must meet the standard. Due to the limitation of the production process, the power cable produced will inevitably have poor insulation such as uneven cable insulation layer, exposed cable conductor, broken skin, and pinholes. Directly affect the insulation performance of the cable. The existing detection methods mostly use batch sampling inspection after the finished cable is finished. Obviously, this method will inevitably lead to unqualified cables due to missed inspections. Even if the problem is found, it will be too late, wasting raw materials and increasing production costs. [0003] In order to solve the above existing problems, people have been seeking an ideal technical solution. Contents of the in...
