A kind of sensor support device for GIS device superfrequency shelf depreciation live detection.
Background technology
With China gas-insulated stacked switch (hereinafter referred to as GIS) extensive use of the equipment in power network, it is in electric power
Importance in system becomes increasingly conspicuous, and GIS breaks down will constitute huge threat to power system security, have a strong impact on power supply
Stability, gently then cause economic loss, it is heavy then cause large-area power-cuts, endanger social stability and safety, therefore
The operation conditions of GIS must be paid much attention to, GIS failure odds is reduced as far as possible.Although what GIS device was run can
Common electrical equipment is higher than by property, but it still occurs more accident in operation, is insulated in GIS failures, cut-off
And close, external force and other three class defects account for more than the 80% of total breakdown, can be divided into the reason for cause these failures manufacture,
Install and other classes of reason three, metal particle and powder for being remained in manufacture etc. are likely to cause GIS failures, in installation process
Conductor overheat when being also possible to cause operation of scratch, the debris that invade, moisture, misloading and neglected loading, flashover even punctures
Etc. accident, other failure causes include designing improper, maloperation and external force destruction etc..
Operating experience shows that GIS can occur shelf depreciation (hereinafter referred to as PD) mostly before it there is electric fault, and PD is
Because internal field's concentration causes dielectric part to puncture produced electric discharge in GIS.GIS inside inevitably exists
Various insulation defects, the electric field that these defects have distorted around it, at some positions, electric field is greatly enhanced, so that exceeding
The disruptive field intensity of dielectric, so as to cause PD to occur, PD long-run developments may cause serious insulation fault.On the one hand
PD is the sign of insulation degradation, and the insulation status of GIS can be learnt by carrying out PD live detections to GIS device, so as to be GIS
Maintenance reference frame is provided, prevention and prevent the generation of major accident, on the other hand, PD is also cause insulation degradation important
Reason, it is necessary to paid attention to, the PD in detection GIS, the safe and reliable operation to ensureing GIS has important practical significance.
Therefore, State Grid Corporation of China's foundation《Q/GDW 1168-2013 power transmission and transformation equipment state overhauling testing regulations》《Q/
