Abstract

A high-voltage GIS equipment breakdown discharge location system based on vibration signals, including: a wireless vibration detector, a control and receiver, and a host computer. Among them, the vibration detector captures the vibration signal of the GIS shell at the moment of discharge through the piezoelectric acceleration sensor and transmits the data to the control and receiver through the zigbee wireless module; the control and receiver can control the startup, data collection and transmission of the vibration detector through buttons function, and display the peak vibration signal and accumulated value of each terminal on the LCD screen; the upper computer completes the display and further analysis of the collected waveform, the call of historical data and other functions. Through the detection system, it is possible to quickly and accurately determine the fault location of the penetrating discharge during the GIS withstand voltage test, which greatly improves the test efficiency of the products of the GIS manufacturing enterprise.

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...
