Abstract

Disclosed is a high voltage GIS device breakdown discharge positioning system based on vibration signals. The system comprises a wireless vibration detection device, a controlling and receiving device and an upper computer. The vibration detection device captures vibration signals of a GIS shell during the discharging instant through a piezoelectric acceleration sensor and transmits data to the controlling and receiving device through a beige wireless module; the controlling and receiving device controls the operation, data acquisition and transmitting functions of the wireless vibration detection device through keys and displays the vibration signal peak values and accumulation values of terminals through a liquid crystal screen; the upper computer has the functions of acquired waveform displaying, analysis and historical data calling. By the aid of the system, the breakdown discharge fault position can be judged rapidly and accurately during GIS voltage resistance tests, and the testing efficiency of products can be improved greatly for GIS manufacture factories.

Description

technical field [0001] The invention relates to the field of penetrating discharge fault location of switchgear in a power system, in particular to a high-voltage GIS equipment penetrating discharge location system based on vibration signal detection and analysis. Background technique [0002] High-voltage GIS equipment is a power equipment that combines busbars, circuit breakers, isolating switches, grounding switches, lightning arresters, transformers and other electrical equipment in a closed metal shell, because of its compact structure, small footprint, and reliable operation High and obvious advantages, more and more widely used in power transmission and transformation systems. At present, the factory inspection of the insulation performance of high-voltage GIS equipment is mainly through the power frequency withstand voltage test. However, due to problems such as high-voltage GIS equipment assembly, product component manufacturing, and processing, the insulation perfo...
