A Simulation Platform for Cable Radial Insulation Damage in Humid Environment

Abstract

The invention discloses a cable radial insulation damage simulation platform in a wet environment. A left lateral sliding track and a right lateral sliding track are arranged at the bottom in a shielding shell; a first support component comprises a left support pillar and a right support pillar which are erected on the left lateral sliding track and the right lateral sliding track, and the left support pillar and the right support pillar are respectively connected with the left end and the right end of a longitudinal sliding bar; one or two lifting platforms which can move longitudinally sheathe the longitudinal sliding bar, and a U-shaped fixture is arranged at the top of the lifting platform; the U-shaped fixture comprises a lateral or longitudinal U-shaped chuck used for clamping a cable, and a hollow acupuncture component and a humidity sensor are also arranged in the U-shaped chuck; and a water filling pipe is respectively connected with each wedge-shaped hollow acupuncture component, and a water injection valve and a water pressure gauge are also respectively arranged at the front end of each connection position. The cable radial insulation damage simulation platform disclosed by the invention has the beneficial effects that fault simulation and radial insulation damage of a cable in different wet environments can be conveniently and effectively realized.

Description

technical field [0001] The invention belongs to the field of cable fault simulation, and in particular relates to a cable radial insulation damage simulation platform in a humid environment. Background technique [0002] In recent years, my country's high-speed railway has developed rapidly, and the electrification rate of railways has continued to increase. Vehicle-mounted cables, mainly ethylene-propylene rubber cables, play an important role in transmitting electric energy. Their usage has increased sharply, and the operating status of cables is directly related to To train operation safety. In actual application, due to factors such as complex railway lines and special structural requirements inside the train, cables often bend to varying degrees, and long-term bending will lead to various performance degradations at the bends. It is more susceptible to moisture intrusion, causing defects such as water branches and electric branches in the insulation of the cable to appe...

AI Technical Summary

Problems solved by technology

However, in actual operation, the radial damage failure of the cable is mainly caused by bending along the radial direction, so the torsion test cannot detect and reflect the ability of the cable to resist radial damage well, nor can it be well To carry out corresponding research on this type of fault, there is no fault simulation device for cable radial insulation damage fault in humid environment.
