Description

technical field [0001] The invention belongs to the field of electrical technology, and relates to a high-voltage GIS online monitoring technology, in particular to an IEC61850-based high-voltage GIS mechanical state online monitoring system. Background technique [0002] High-voltage GIS is a very critical equipment in the power system. If a fault occurs during operation and cannot be dealt with in time, it may bring serious harm to the operation of the power grid. In recent years, with the prosperity and development of my country's economic construction, the demand for power system capacity and energy has increased, and higher and higher requirements have been put forward for the reliability and economy of the power system. For high-voltage GIS, the mechanical failure of the operating mechanism and the transmission mechanism, as well as the failure of the electrical control and auxiliary circuits often cause serious mechanical failures. In order to avoid serious mechanica...
