This application is applicable to the technical field of electrical equipment insulation detection, and provides a quantitative evaluation method and device for the degree of insulation deterioration between turns of coil equipment, including: after injecting detection pulses into both ends of the coil to be detected through the pulse generating device, Receiving reflected pulses corresponding to the detection pulses at both ends of the coil to be detected by the pulse receiving device; calculating the characteristic waveforms of the two reflected pulses received, and calculating the fault degree factor corresponding to the characteristic waveforms; The insulation degradation degree grade corresponding to the fault degree factor is searched in a preset degree grade table. Through the above method, the degree of deterioration of the inter-turn insulation of the coil can be quantitatively evaluated, thereby effectively preventing the occurrence of inter-turn short circuit faults.
Description
technical field [0001] The present application relates to the technical field of electric equipment insulation detection, and in particular to a quantitative evaluation method, device and terminal equipment for the deterioration degree of inter-turn insulation of coil equipment. Background technique [0002] With the development of social economy and the continuous increase of power demand, higher requirements are put forward for the quality and reliability of power supply. Power equipment is the core of the power system, carrying the tasks of energy development, conversion, and transmission, and is also the specific executor of power generation, transmission, transformation, and transmission. Generators, switchgear, transformers, reactors, etc., as key power equipment in power systems, are important components for power generation, transmission and supply, and their safe and stable operation has a huge impact on power grids and even economic and social development.
