Problems solved by technology
[0002] Abnormal mechanical vibrations often occur in gas insulated metal-enclosed switchgear (GIS) operation, and long-term vibration may lead to loosening of conductive rods and insulating parts, causing partial discharge, and even insulation accidents
[0003] At present, GIS equipment online monitoring and fault diagnosis technologies, such as UHF method, are mostly aimed at discharge defects, and it is difficult to detect mechanical vibration defects early. The existing vibration tester and ultrasonic partial discharge detector can reflect the vibration of GIS equipment , but manual single-point measurement is required, which is time-consuming and laborious, and cannot reflect the vibration and load changes of GIS equipment

The invention discloses a device and method for wirelessly monitoring vibration and load change of GIS equipment, which belong to the technical field of GIS wireless monitoring. The device comprises a sensor unit which is installed on the surface of GIS equipment or a potential connection bar of the GIS equipment and obtains a vibration signal and a load current signal of the GIS equipment, an acquisition unit which is used for acquiring the vibration signal and the load current signal acquired by the sensor unit and transmitting the acquired vibration signal and the load current signal to an edge calculation unit, the edge calculation unit which is used for extracting diagnosis results of the vibration signals and the load current signals and transmitting the diagnosis results to a man-machine interaction unit, and the remote man-machine interaction unit which is used for receiving the diagnosis result transmitted by the edge calculation unit and carrying out wireless monitoring on vibration and load change of the GIS equipment according to the diagnosis result. Thus, the power supply reliability of the GIS equipment is improved.
Description
technical field [0001] The invention relates to the technical field of GIS wireless monitoring, and more particularly, to a device and method for wirelessly monitoring vibration and load changes of GIS equipment. Background technique [0002] Abnormal mechanical vibrations often occur in gas insulated metal-enclosed switchgear (GIS) operation, and long-term vibration may lead to loosening of conductive rods and insulating parts, causing partial discharges, and even insulation accidents. [0003] At present, GIS equipment online monitoring and fault diagnosis technologies, such as UHF method, are mostly aimed at discharge defects, and it is difficult to detect mechanical vibration defects early. The existing vibration tester and ultrasonic partial discharge detector can reflect the vibration of GIS equipment , but manual single-point measurement is required, which is time-consuming and laborious, and cannot reflect the vibration and load changes of GIS equipment. Therefore, ...
