[Abstract]:Power transformer is one of the most important electrical equipment in power system. The real-time on-line monitoring of transformer's running state can timely warn transformer faults and avoid serious accidents. At the same time, it can also provide the main reference information for transformer maintenance after failure, saving maintenance costs. It is of great significance to the whole power industry. The sensor used in transformer on-line monitoring is the key device of transformer on-line monitoring. The research on the design and application of transformer sensor for on-line monitoring has high research value and application prospect. In this paper, the development status of transformer on-line monitoring is analyzed, and several main sensors used in transformer on-line monitoring are listed. Then, the main fault characteristic signals (overvoltage) are given. Partial discharge (PD) and dielectric loss are studied. Theoretical analysis and simulation of main fault signals on transformer bushing are carried out. Combined with the research results, the design requirements of on-line monitoring sensor performance are obtained. At the same time, the principle of various transformer on-line monitoring sensors is analyzed theoretically. According to the research results of the fault signal, the sensor is designed and manufactured for on-line monitoring the main fault signals of the transformer. Finally, an experimental system is built to test the performance of the transformer. The installation position of the designed sensor and the fusion design of the sensor and transformer are described, and the design and application of the integrated sensor are proposed.
