Description
technical field [0001] The invention belongs to the field of real-time on-line measurement and detection of the temperature rise of live high-voltage cables, and in particular relates to an on-line measurement and detection device for realizing the temperature rise of cables by reflection high-energy electron diffraction spectrum. Background technique [0002] The safe operation of power equipment has always been an issue that departments at all levels in the power, steel, petrochemical and other industries attach great importance to. Over the years, although many safety measures and technologies have been adopted, there are still many hidden dangers and safety accidents still occur from time to time. In power plants and substations, cable trays, cable tunnels, cable interlayers, cable trenches, cable shafts, switchgears, transformers, resistors and other power equipment in the long-term high voltage heating and aging cause fires. After years of fire investigation and resear...
