The invention provides a GIS abnormal heating monitoring system based on a SiPM sensor, and the system mainly comprises the SiPM sensor, a Fresnel lens, a signal processing unit, a data collection unit, and a computer terminal, and the monitoring system is used for monitoring the abnormal heating of a GIS and carrying out the early warning. The SiPM sensor is arranged at the window of a GIS equipment cavity, the Fresnel lens is arranged between one end of the SiPM sensor and an internal discharge source of the GIS equipment, the other end of the SiPM sensor is connected with one end of the signal processing unit, and the other end of the signal processing unit is connected with the computer terminal through the data acquisition unit. According to the invention, the thermal infrared signal of abnormal heating in the GIS equipment is converted through the SiPM sensor, and the converted electric signal is processed by the signal processing unit, so that the temperature display and early warning of abnormal heating in the GIS equipment are realized, and the system has the advantages of strong anti-interference capability and high detection accuracy.
Description
technical field [0001] The present application relates to the technical field of power equipment status monitoring, and in particular to a monitoring system for abnormal heating of a GIS based on a SiPM sensor. Background technique [0002] In GIS equipment status detection, the diagnostic method used to detect abnormal heating defects and fault types inside GIS is usually used as an analysis method for partial discharge ultrasonic measurement results. GIS equipment has the advantages of small footprint, compact structure, high reliability, low noise and small daily maintenance workload, so it has been widely used in modern power systems. However, due to its complex structure and strong sealing, when an internal insulation fault occurs, it will cause a large-scale power outage, and the maintenance time required is longer than that of conventional equipment. With the increase of the voltage level, the increase of the number of equipment and the increase of the service life, ...
