The factors such as the presence of electric impurity, the Ageing of Insulators all most likely result in electric discharge and flashover within GIS.And GIS device is customary
In the routine test having a power failure project fewer it is difficult to find its internal insulation defect, these defects are often through sending out further
Exhibition, can lead to GIS to damage.
With the popularization of grid equipment repair based on condition of component theory, all kinds of hotline maintenance technology are developed rapidly.To operation
In GIS device carry out superfrequency Partial Discharge Detection, diagnosis whether there is partial discharge phenomenon, and be acknowledged as one kind has very much
The live detection means of effect, can timely find conductor burr, metallic particles, insulant present in GIS operation equipment
The defects such as air gap, it is to avoid major accident occurs.Need during superfrequency Partial Discharge Detection each air chamber of equipment is carried out sternly
The detection of lattice, reliably excludes the interference signal, and just can accurately analyze the situation of GIS device operation.But hold with transformer station
The continuous expansion of gauge mould, the electrical separation data of GIS device is also on the increase, and leads to detect that workload is very huge.According to
The requirement of DL/T393-2010 power transmission and transformation State Overhaul Test code, power transformation every half a years more than 330 kilovoltage grades is to GIS
Equipment carries out a superfrequency Partial Discharge Detection.But find in real work, carried out by testing staff's hand-held sensor
The mode of detection has significantly limit the efficiency of detection, and a lot of GIS device erection is higher, has personnel to carry out
Under the mode that hand-held sensor is detected, need, by insulation step ladder, to carry seat belt of ascending a height, placement sensor of ascending a height enters
Row detection, when changing test point, will move insulating ladder again, re-start placement sensor, substantial amounts of time consumption in detection work
Take in carrying insulating ladder, in the work placing sensor of ascending a height, this kind is placed approach sensor and greatly limit detection work
Efficiency.
