Large cable paying-off, taking-up and testing device

Abstract

A large cable paying-off, taking-up and testing device comprises a left support and a right support. The left support and the right support are connected with a main shaft in a rotating mode, the main shaft is provided with a roller, a left baffle and a right baffle are arranged at the two ends of the roller, a storage battery, a motor and a gearbox are arranged on the left of the left support, the motor is in transmission connection with one end of the main shaft through the gearbox, the main shaft is coaxially provided with a connecting cylinder located between the left support and a bracket of the left baffle, the connecting cylinder is sleeved with an insulation sleeve, four annular grooves are formed in the outer surface of the periphery of the insulation sleeve in the circumferential direction, four copper rings are arranged in the four annular grooves respectively, two opposite sides of each copper ring are provided with a first conductive contact and a second conductive contact respectively, the four first conductive contacts are each connected with a copper bar, a wiring board is arranged at the outer ends of the four copper bars, and the left baffle is provided with a cable outlet. The large cable paying-off, taking-up and testing device can be used for achieving automatic fixing and automatic taking-up and paying-off and can also be used for conducting an insulation resistance test, a leakage current test, a direct-current withstand test, a dielectric loss factor test and an alternating current withstand test on cables.

Description

technical field [0001] The invention belongs to the technical field of electric power industry construction, and in particular relates to a large-scale cable release and take-up and testing device. Background technique [0002] At present, when the cable is drawn, the release and take-up frame is generally used as the release tool, and the manual release and take-up is generally used. However, when the cable is long or thick, it is more difficult to use manual take-up and take-off. In addition, The existing release and take-up racks generally do not have a device for fixing cables, but the feeder cables from the pay-off rack to the electric load are generally more than 25 meters long, and it takes several Only individuals can complete it, which is time-consuming and laborious, very inconvenient, and the construction efficiency is low. In addition, the existing cable take-up and take-off stand can only carry out take-up and take-off operations, and has a relatively singl...
