Abstract
Aiming at the over-reliance on the inefficient operation of transformers and circuit breakers in the field of substation, introduced the special advantages of fault wave recorder on-site monitoring of substation primary equipment, and expounded the technical principle of extracting transformer and circuit breaker state parameters by wave recording data. This paper presented a design scheme of remote on-line monitoring, acquisition, evaluation and distribution of integrated platform for transformer and circuit breaker equipment based on dispatching data network, and realized the wide area monitoring, information sorting, feature recognition, fault research and status evaluation, and introduced the long-term mechanism of regular feature library with self-learning ability to ensure the scientific and applicability of system decision-making. The operation effect of Guangzhou Power Supply Bureau has verified the accuracy of system failure judgment and potential defect prediction, and enhanced the state evaluation ability of transformer and circuit breaker, and raised the level of operation and maintenance of high equipment.
