Research on intelligent detection technology of oil-immersed current transformer based on ubiquitous electricity internet of things
Aiming at the existing methods of long inspection cycles, failure to identify subtle fault symptoms, delay in processing time, and causing vicious accidents such as equipment injection, explosion, fire, etc, this article introduces a design of an intelligent detection device for NB-IoT narrowband IoT data transmission Solution, the detection system is divided into perception layer, network layer and application layer.Minimize the risk of sensor installation while maintaining the original structure of the device, and adopt a portable design, plug and play.Using the narrowband IoT, the coverage is wide, the transmission is stable, the abnormal working conditions of the equipment can be quickly identified and diagnosed, and early detection and early treatment of equipment failures are realized.It is proposed to formulate double criterion standards for oil level and oil temperature, further optimize the online monitoring method based on the oil and gas pressure monitoring device, and use equipment intelligent pre-diagnosis technology to facilitate personnel to perform horizontal and vertical comparison.
