Description
Technical field
The utility model relates to a kind of GIS partial discharge ultrasonic sensor fall-proofing device, belong to electric system GIS(Cubicle Gas-Insulated Switchgear) the dropproof technical field of shelf depreciation ultrasound examination sensor.
Background technology
GIS has higher reliability and applicability, but from ruuning situation, fault is still inevitable.Domesticly there occurs several more serious GIS faults, GIS is raw, and fault often causes long-time power failure, and recondition expense is high, certainly will bring about great losses.GIS has not allowed shelf depreciation to exist under normal operating voltage, national regulations: GIS is high-volume not more than 10pC at interval of office.Once cause shelf depreciation, as tip causes electric field uneven due to certain defect; Electrically conductive particles beat under high electric field produce electric discharge and superstructure loosening, loose contact electric discharge, all can reduce dielectric strength dramatically.
Ultrasound wave Partial Discharge Detection is a kind of GIS live detection technology of in recent years rising, and it utilizes portable ultrasonic sensor to gather GIS and operationally conducts to the ultrasonic signal of shell thus judgment device internal discharge degree or superstructure loosening etc.Just because of ultrasound examination is in the starting stage, practical level needs further, and as sensor still needs hand-held, and compression degree during test between sensor and GIS cylinder blanket will affect the collection of signal, reduce fault recall rate.At present, also sensor is avoided to fall without perfect measure and the present situation of insufficient compression between sensor and GIS shell.
At present, from operation and maintenance experience, GIS ultrasound wave Partial Discharge Detecting Technology is comparatively sensitive to defects such as the point discharge on GIS inner conductor, metal parts loosen.Sensor colligation not firmly can make the data distortion collected, and departs from actual value, causes the erroneous judgement of data, defect fails to judge.In order to improve ultrasound wave Partial Discharge Detection defect detection rate in GIS routine testing further, need improve existing checkout equipment, solving sensor when testing and easily falling the problem that can not fully contact with GIS surface with sensor.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to use and reliable, the security of portable measuring device with electricity, the stability of continuous coverage, the reliability of test data can be improved, ensure that the GIS partial discharge ultrasonic sensor fall-proofing device of GIS device safe operation.
The purpose of this utility model has been come by following technical solution, described GIS partial discharge ultrasonic sensor fall-proofing device, it comprises the metal framework that can be placed with ultrasonic sensor in the middle of, and described ultrasonic sensor is installed in the bottom of metal framework and can be contacted with the surface of apparatus casing with metal framework; Be provided with in the bottom of described metal framework and self absorption affinity can be utilized to be adsorbed in apparatus casing surface and make the adsorber of metal framework bottom surface and apparatus casing surface contact.
At least three edged surfaces of described metal framework bottom surface are respectively provided with an adsorber formed with the sucker that quality of rubber materials is made respectively, and described metal framework aluminum alloy materials is made, its periphery key fixing ultrasonic sensor is installed.
The utility model charged carry out Partial Discharge Detection time, the ultrasonic sensor being arranged on metal framework is fixed on GIS case surface by the adsorber being placed in corner by sensor fall-proofing device, it is made not easily to be subjected to displacement, fall, and fixing simple, sensor contacts is abundant, avoid in operation due to equipment operating vibration, the concussion that operational outfit etc. cause causes probe-shift, landing, cause because of factors such as Sasser intrusions thus make the data distortion collected, depart from actual value, erroneous judgement, the defect of making paired data are failed to judge; It is simple that it has structure, easy to use and reliable, can improve the security of portable measuring device with electricity, the stability of continuous coverage, the reliability of test data, ensure that the features such as GIS device safe operation.
Accompanying drawing explanation
Fig. 1 is metal framework earth construction schematic diagram described in the utility model.
Fig. 2 is the structural representation of sucker described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, GIS partial discharge ultrasonic sensor fall-proofing device described in the utility model, it comprises the metal framework 2 that can be placed with ultrasonic sensor 1 in the middle of, and described ultrasonic sensor 1 is installed in the bottom of metal framework 2 and can be contacted with the surface of apparatus casing with metal framework 2; Be provided with in the bottom of described metal framework 2 and self absorption affinity can be utilized to be adsorbed in apparatus casing surface and the adsorber 3 making metal framework bottom surface and apparatus casing surface contact.
It shown in an adsorber 3, Fig. 1 formed with the sucker that quality of rubber materials is made is four each settings in bight that at least three edged surfaces of described metal framework 2 bottom surface are respectively provided with respectively; Described metal framework 2 is made with aluminum alloy materials, its periphery key fixing ultrasonic sensor 1 is installed.
Sensor and adsorber are combined by the utility model, by the absorption affinity of adsorber, sensor are fixed on apparatus casing surface tightly, reach fully contact and dropproof object.This device adopts aluminum alloy frame, and 4 adsorbers are placed in framework corner respectively, and sensor occupy middle; Adsorber is the sucker of quality of rubber materials.
