Abstract

The invention discloses a GIS fault diagnosis system and method thereof. The system includes a vibration signal acquisition module, a UHF signal acquisition module, an ultrasonic signal acquisition module and a PC. The vibration signal acquisition module includes a vibration signal processing module, a vibration signal acquisition instrument and Several vibration sensors, each vibration sensor collects vibration signals and sends them to the vibration signal acquisition instrument after being processed by the vibration signal processing module. The UHF signal acquisition module includes UHF signal processing module, UHF signal acquisition instrument and several UHF antennas. The high-frequency antenna collects UHF signals and sends them to the UHF signal acquisition instrument after being processed by the UHF signal processing module. The ultrasonic signal acquisition module includes an ultrasonic signal processing module, an ultrasonic signal acquisition instrument and several ultrasonic sensors. The signal processing module sends it to the ultrasonic signal acquisition instrument after processing. The invention solves the problem that a single diagnosis method cannot comprehensively evaluate the running state of the GIS.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment maintenance, and in particular relates to a GIS fault diagnosis system and a method thereof. Background technique [0002] Gas-insulated metal-enclosed switchgear (GIS), which combines circuit breakers, disconnectors, fast (earth) switches, current transformers, voltage transformers, surge arresters, busbars (three-phase or single-phase), connecting pipes and transition elements, etc. Combined in a fully enclosed metal shell, the medium used for insulation and arc extinguishing in the shell is SF6 gas of 0.4-0.6MPa. [0003] GIS equipment was born in the mid-1960s. With the continuous maturity of technology, the area and volume of GIS equipment are getting smaller and smaller, and the operation is becoming more and more reliable. The failure rate and maintenance workload of GIS put into operation in the early stage are also obvious. It is lower than other types of switchgear in the s...
