Description
Technical field
The present invention relates to the fixed device of power equipment and fixing means, and in particular to a kind of GIS ultrahigh frequency sensor is fixed
Device and its application method.
Background technique
Currently, the quantity of GIS substation is continuously increased with the development of power grid construction.But once insulating inside GIS
Defect easily causes equipment fault, and caused power off time is longer, maintenance expense it is also very high, the country have occurred that several compared with
For serious GIS accident.CIGRE investigation shows that 50% or more GIS failure can be found in advance.With sensor and letter
The development of number processing technique, superfrequency [UHF] Partial Discharge Detecting Technology are applied to GIS partial discharge by more and more extensive
Live detection, and succeed in many defect diagonsis cases.Although superfrequency detection technique is constantly mature, answering
With there is also many deficiencies to need to be promoted.In general, GIS ultrahigh frequency detection system is by being built in GIS shell or being arranged
Sensor outside disc insulator carries out signal acquisition, then carries out signal processing analysis by host.Currently, major part GIS
Superfrequency detection then rely on outer sensor carry out signal acquisition, since GIS device is all mounted in cylindrical tube, thus
The fixation of sensor is a problem.Current existing measure is it to be fixed using binding strap, but method is not only time-consuming takes
Power, application range are only limitted to the interval GIS of space spaciousness.And GIS device space occupied is small at present, and can be with stereoscopic configurations, institute
It is all very compact with the space in GIS distribution place, enough spaces even more are not reserved to the detection in later period and maintenance, especially
For remote apart from ground and be difficult to carry out at the fixed disc insulator of binding strap, UHF band electro-detection be faced with sensor without
The problem of method is reliably fixed:
1.GIS equipment component is higher apart from ground, and when detection generally requires by ladder, if still being sensed using man-hour manually hand-held
Device measures, and easily there is a situation where the person is in contact with GIS shell, and this adds increased operation Danger Electric shock risks, so that surveying
Amount worker is difficult to attentively measure, therefore is also difficult to accurately measure；
2. man-hour manually hand-held sensor measures, once GIS generation high-pressure conductor discharges over the ground or disconnecting switch abnormal operation,
Shell will become electrical body or have induced electricity at this time, this will directly threaten the personal safety of staff；
3. artificial long-time operation be easy to cause tired using traditional hand-held sensor or artificial progress high-rise working binding
Labor is unfavorable for continuing, efficiently detect.
Therefore, tester operator need be freed from original measurement method.
Summary of the invention
Main inventive purpose of the invention, one is to provide a kind of GIS ultrahigh frequency sensor fastening device, and two are to provide one kind
The application method of the GIS ultrahigh frequency sensor fastening device.
