Description
Technical field
This utility model relates to a kind of for electro-detection aid, is specifically related to a kind of GIS equipment partial discharge detection bar.
Background technology
Shelf depreciation refers to the electric discharge phenomena occurred in certain region in insulation of electrical installation structure, and this electric discharge is the most absolutely
Edge structure is destroyed in this region, and major insulation does not occur penetrability to puncture, if but shelf depreciation long-term existence, at certain bar
Decline and the damage of equipment major insulation electrical strength can be caused under part.If there is internal field in insulation system, higher (field intensity is divided
Cloth is uneven), or insulate in manufacturing process imperfection, operation Organic substance decomposition, solid insulation are by mechanical force generation cracking etc.
Reason forms defect, and these positions operating are easy for insulation breakdown is occurred, shelf depreciation occurs.Superfrequency detection technique,
The office utilizing superfrequency sensor detection electrical equipment puts, thus avoids electrical hazard.
Present stage, in SF6 combined electrical apparatus partial discharge detection, when GIS device is carried out by testing staff with superfrequency sensor
During superfrequency detection, need superfrequency sensor to be positioned over above disc insulator.In practical operation, often run into frame
The air chamber pipeline that sky additionally arranges, being now accomplished by ascends a height with insulating ladder or scaffold detects, owing to test point is than comparatively dense, must
Must frequently move ladder and become detection position.Owing to whole detection is to carry out in charging equipment district, frequently ascends a height and move, can be right
Testing staff constitutes security threat, and work efficiency is extremely low.
Summary of the invention
The purpose of this utility model is aiming at the defect that prior art exists, it is provided that a kind of GIS equipment partial discharge inspection
Measuring staff.
Its technical scheme is: a kind of GIS equipment partial discharge detection bar, including superfrequency sensor and insulating bar, described
Insulating bar includes motion bar, locating part and sleeve pipe, is provided with female thread in described sleeve pipe, and one end of described motion bar is provided with transmission
Head, driving head is provided with external screw thread being rotatably assorted with sleeve pipe female thread and is connected, and the other end of motion bar is provided with universal joint, special
High frequency sensors is arranged on the front end of universal joint by fixture, and the one end that sleeve pipe intersects with motion bar is provided with locating part,
The rear end of sleeve pipe is provided with fast fitting.
Wherein, the length of described motion bar is more than the length of sleeve pipe.The diameter of described driving head is identical with the internal diameter of sleeve pipe
And more than the diameter of motion bar.Described locating part be longitudinal section be the column structure of convex character shape, be provided with in the middle part of this column structure with
The through hole that motion bar diameter matches, the taper end of locating part convex character shape column structure is provided with external screw thread.Described fast fitting is arranged on
The external screw thread of insulating bar sleeve pipe rearward end or female thread.Described insulating bar middle sleeve rear portion is provided with insulation protective jacket.
The beneficial effects of the utility model are:
1, utilize insulation rod device auxiliary detection, avoid the need for ascending a height operation greatly and the potential safety hazard brought, with
Time be easy to quickly detect；Without security threat, and work efficiency is high；
2, telescopic insulating bar is easy to detect the electrical equipment of differing heights, simultaneously, moreover it is possible to increase extension rod, user
Just；
3, adjustable universal joint so that it is have certain damping force, maintains the operating angle of manual alignment jig.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of this utility model；
Fig. 2 is the structural representation of motion bar in this utility model；
Fig. 3 is the structural representation of locating part in this utility model.
Detailed description of the invention
