Description

technical field [0001] The invention relates to an on-line monitoring device for a switchgear in a power system, in particular to a device that combines advanced MOEM (Micro-Optical-Electro-Mechanical System) optical fiber sensing technology with computer data acquisition and analysis technology. Combined with network communication, an online monitoring device for power system switchgear parameters based on optical fiber sensor technology is realized. Background technique [0002] The power system switchgear is an important equipment in the power system, and its good operation is of great significance to the safety of the power grid. However, during the operation of the power system switchgear, due to the inevitable influence of various factors such as electricity, heat, vibration, environment, and insulation aging, its technical performance continues to deteriorate, resulting in poor operating conditions. At present, regular maintenance and safety tests are the main means ...
