Problems solved by technology
[0005] In recent years, with the rapid development of the power industry towards high voltage, large units, and large capacity, the transformers in power equipment are also developing towards complexity, large scale, and multi-function. The failure mechanism is complex, the fault concealment is strong, and the type and degree are not easy to detect. Therefore, if the power transformer can be synchronously and accurately obtained from the temperature of the winding hot spot in the power transformer, the temperature of the oil chamber of the on-load tap changer, and the oil level of the oil conservator, etc. The characteristics of multiple key physical parameters of the real-time state provide a reliable basis for the effective monitoring of the power system operating state. In this way, the conventional monitoring system for local equipment and a single parameter of the power transformer can no longer meet the requirements of the actual application field for accuracy, real-time Higher requirements for performance, reliability and stability

Embodiment Construction
[0028] figure 1 It is the model diagram of the multi-agent fiber grating transformer intelligent monitoring system constructed in this embodiment. In the model diagram, firstly, the whole system is decomposed into a plurality of easy-to-implement subsystems, and converted into corresponding intelligent agents, so that the original The serial processing optical fiber intelligent monitoring system implemented by the central processor becomes a parallel distributed monitoring system.
[0029] First, in the optical fiber sensing layer, the winding hot spot temperature optical fiber sensing body, the oil conservator oil level fiber optic sensing body, and the on-load tap changer oil chamber temperature fiber optic sensing body respectively collect the relevant physical parameter data of the power transformer. After the data is transmitted to the data processing layer, the data processing layer analyzes and processes the corresponding data obtained, and the processed data is transmi...

Description
Technical field: [0001] The invention belongs to the technical field of transformer monitoring, and in particular relates to an intelligent monitoring system based on a multi-body technology for distributed transformer winding hot spot temperature, on-load tap changer oil chamber temperature, and transformer oil level based on a fiber grating sensor. Background technique: [0002] As the country's pillar energy and economic lifeline, electric power's safe and stable operation is not only related to the country's economic development, but also maintains national security. In the power system, the power transformer is the core of energy conversion and transmission in the power grid, and is the only way for the energy source of all walks of life in the national economy and thousands of households. If a large-scale power transformer fails during system operation, it may cause a large-scale power outage, and its maintenance period generally takes more than half a year, causing hu...
