Abstract

The invention relates to GIS ultrahigh frequency-optical signal consistency test equipment, device and method. The equipment comprises a pulse generator, a light source controller, a switch, a test chamber, an ultrahigh-frequency transmitting sensor, a light source, an ultrahigh-frequency receiving sensor, a photomultiplier tube and an oscilloscope. The input end of the switch is connected with the pulse generator and the light source controller; the output end of the switch is connected with the ultrahigh-frequency transmitting sensor and the light source; the ultrahigh-frequency receiving sensor and the photomultiplier tube are connected with the oscilloscope; the ultrahigh-frequency transmitting sensor and the light source are arranged at one end of the test chamber; the ultrahigh-frequency receiving sensor and the photomultiplier tube are arranged at the other end of the test chamber; the test chamber is internally provided with an accommodation groove for holding an obstacle; andthe accommodation groove is arranged between the light source and the photomultiplier tube, and between the ultrahigh-frequency transmitting sensor and the ultrahigh-frequency receiving sensor. Compared with the prior art, the GIS ultrahigh frequency-optical signal consistency test equipment, device and method can test influence laws of various obstacles on the consistency of light and ultrahigh-frequency signals generated through discharge.

Description

Technical field [0001] The invention relates to the field of electrical equipment measurement, in particular to a GIS medium and high frequency-optical signal consistency test equipment, device and method. Background technique [0002] Large-scale power transformers and gas-insulated metal-enclosedswitchgear (GIS) are the most important equipment in the current power system, and their operational reliability is directly related to the safety and stability of the grid system. Inside the GIS, defects such as metal tip and floating potential occur from time to time. Once the defect occurs, it will cause partial discharge. The use of UHF method to detect partial discharge of GIS internal defects has been widely used. Although UHF method itself has strong anti-interference ability, there are still various sources of external space in field testing and laboratory research. Class interference, sometimes it is difficult to distinguish the partial discharge signal of the interfering sign...
