True cable fault simulation system

Abstract

The invention discloses a real cable fault simulation system. The system comprises an ablation simulation unit which is used for carrying out ablation simulation on a target cable, and the target cable is a cable which needs to be subjected to ablation simulation; the voltage applying unit is used for applying voltage to the target cable in the ablation simulation process of the ablation simulation unit on the target cable; the gas detection unit is used for collecting predetermined gas generated by the ablation simulation unit in the ablation simulation process of the target cable by the ablation simulation unit; and the gas detection unit is also used for analyzing the predetermined gas so as to determine ablation information of the buffer layer of the target cable based on an analysis result. The technical problem that certain potential safety hazards are caused to safe and stable operation of a power system due to the fact that whether the buffer layer of the high-voltage cable is damaged or not cannot be effectively detected in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of power system detection, in particular to a true cable fault simulation system. Background technique [0002] At present, the 110kV high-voltage cables in my country are mainly water-blocking cables with corrugated aluminum sheaths, and the buffer layer is located between the aluminum sheath and the insulating outer shield. The buffer layer can effectively buffer the extrusion, twisting and bending stress during the construction process, and can effectively prevent the extension of moisture along the length of the cable. However, in the power system, a large number of cable body insulation breakdown accidents are prone to occur due to the ablation failure of the cable buffer layer, which seriously threatens the stability of the power system operation. From the on-site cable buffer layer failure, it can be found that a large number of ablation white spots appear on the surface of the cable buffer layer and...
