Description
Technical field
The utility model relates to GIS partial discharge monitoring field, is specifically related to the uhf sensor for a kind of novel local On-line Discharge monitoring of transformer station's GIS power equipment.
Background technology
Shelf depreciation refers to the electric discharge that Electric Power Equipment Insulation occurs in subrange under enough strong electric field action.The initial stage that shelf depreciation occurs does not affect the normal operation of switch, but due to the continuous destruction of shelf depreciation to dielectric strength, runs through after insulation until form path, and switchgear accident just can occur.The most accidents of transformer station are all caused by power equipment shelf depreciation, office puts on-line monitoring and can monitor and follow the trail of the shelf depreciation occurring in GIS equipment, the development trend that this innings of forecast in time put and prediction relevant device insulation degradation degree, prevent paroxysmal electrical hazard, improve the safe reliability of GIS operation.
It is exactly that sensor is put in ultrahigh frequency office that office is placed on line monitoring system important component part, the external ultrahigh frequency office existing at present puts sensor one end and is fixedly connected with by bandage with GIS equipment disc insulator or plug hole, the other end is connected with detecting signal unit by concentric cable, swivel nut is connected with the protective jacket outside concentric cable, sensor contact is connected with concentric cable, swivel nut and sensor contact are all fixed sturcture, can not flexible rotating, narrow and small when running into the device space, concentric cable and protection tube are installed and are had certain difficulty, concentric cable and protective jacket can be forced to wide-angle bending, when serious, cause poor contact of contacts.
Utility model content
The utility model mainly solves the technical matterss such as uhf sensor complex structure, installation and use inconvenience, contact and the swivel nut sensitvity constraint system of existing partial discharge monitoring, and a kind of uhf sensor of simple in structure, easy for installation, highly sensitive partial discharge monitoring is provided.
For achieving the above object, the utility model provides following technical scheme: a kind of uhf sensor of novel local On-line Discharge monitoring, comprises composition surface, inductor, swivel nut, contact, swivel nut base, rotor and armature spindle; Described composition surface is closely connected to inductor lower end, described inductor inside is provided with rotor, in the middle of described internal rotor, be provided with armature spindle, be rotated by armature spindle, described swivel nut base, contact are fixedly mounted on rotor, can rotate freely zero degree with rotor arbitrarily angled to 90 degree, described swivel nut is connected with swivel nut base, described contact is located at swivel nut inside, and bottom, described contact is provided with wire, and described wire is connected with inductor through rotor.
Compared with prior art, the beneficial effects of the utility model are: the uhf sensor of partial discharge monitoring is placed in GIS device external by composition surface, installation and use are more convenient, inductor with contact near distance with GIS equipment, there is higher sensitivity, can monitor in time the partial discharge phenomenon in GIS equipment; Swivel nut, contact are connected with the rotor of inductor inside, rotor is rotated by armature spindle, swivel nut and contact can 0 ° ~ 90 ° Arbitrary Rotations, solve the installation difficulty that narrow space causes, concentric cable and protection tube needn't wide-angle bendings, simple in structure, good looking appearance, practical.

Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
A uhf sensor for novel local On-line Discharge monitoring, comprises composition surface 1, inductor 2, swivel nut 3, contact 4, swivel nut base 5, rotor 6 and armature spindle 7; Described composition surface 1 is closely connected to inductor 2 lower ends, the uhf sensor of partial discharge monitoring is all crossed composition surface 1 and is placed in GIS device external, inductor 2 with contact near distance with GIS equipment, there is higher sensitivity, can monitor in time the partial discharge phenomenon in GIS equipment; Described inductor 2 inside are provided with rotor 6, described rotor 6 bosoms are provided with armature spindle 7, described rotor 6 is rotated by armature spindle 7, described swivel nut base 5, contact 4 are fixedly mounted on rotor 6, can rotate freely 0 degree with rotor 6 arbitrarily angled to 90 degree, and described swivel nut 3 is connected with swivel nut base 5, described contact 4 is located at swivel nut 3 inside, 4 bottoms, described contact are provided with wire, and described wire is connected with inductor 2 through rotor 5, is convenient to signal transmission.
The utility model is in the time of work, because swivel nut base 5 and contact 4 are fixedly mounted on rotor 6, contact 4 is located at swivel nut 3 inside, it is arbitrarily angled to 90 degree that swivel nut 3 can rotate freely 0 degree with rotor 6 by armature spindle 7, contact 4 ends have wire to pass rotor 6 to be connected with inductor 2, so that signal transmission, wire has certain flexibility, in rotor 6 rotation processes, can not affect the transmission of signal, assurance function and stablizing of contacting, and inductor 2 with contact near distance with GIS equipment, there is higher sensitivity, can monitor in time the partial discharge phenomenon in GIS equipment.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the present invention.
In addition, be to be understood that, although this instructions is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
