Problems solved by technology
[0003] Existing GIS equipment SF6 leakage detection technology can only be measured by contact, or because the signal-to-noise ratio is too low, it can only be used for short-distance telemetry. The detection distance is short and the range is small. Only a single leak can be monitored online, or suspected Leak detection at close range
Unable to achieve large-scale, dynamic and uninterrupted online monitoring of the entire substation by a single device
At the same time, many GIS equipment and their pipelines in UHV substations are high above the ground, and it is difficult to detect leaks with existing short-distance detection equipment.

The invention discloses an SF6 leakage detection system and method of a GIS of a transformer station, and relates to the technical field of fluid tightness of structural parts. The system comprises a Fourier infrared spectrometer, a scanning holder and a programmable control robot dolly, wherein the scanning holder is arranged on the robot dolly, and can make horizontal and pitching rotation relative to the dolly, the spectrometer is fixed on the scanning holder, and the scanning holder can drive the spectrometer to make horizontal and pitching rotation relative to the dolly. The Fourier infrared spectrometer is used to realize long-distance, large-range and one-to-multiple SF6 leakage detection and location, use is convenient, and the working efficiency is high.
Description
technical field [0001] The invention relates to the technical field of testing methods for fluid tightness of structural components, in particular to a system and method for detecting SF6 leakage of substation GIS equipment. Background technique [0002] Due to the excellent insulation and arc extinguishing properties of sulfur hexafluoride (SF6) gas, at present, in my country's power system, sulfur hexafluoride electrical equipment, especially sulfur hexafluoride fully enclosed combined electrical equipment (GIS), has been widely used . The detection of sulfur hexafluoride gas leakage is an important part of equipment operation or daily maintenance. Up to now, SF6 gas leak detection still stays in contact measurement or short-distance telemetry, using single-to-single or multi-to-single detection methods, and there is still no long-distance, large-scale single-to-multi-point leak detection technology at home and abroad. The one-to-one online detection not only increases th...
