Description
Technical field
The utility model relates to high-tension electricity detection technique field, particularly relates to a kind of GIS partial discharge locating device.
Background technology
Shelf depreciation refers to the electric discharge phenomena that the insulation system of power equipment occurs in regional area under enough strong electric field action.Although this shelf depreciation only can cause, the subrange of insulation system is breakdown causes local short circuit, and the insulation between the conductor of power equipment penetrability does not occur and punctures, and shelf depreciation all can have some to affect on insulating medium each time.In addition, the impact of slight shelf depreciation on Electric Power Equipment Insulation is less, and the decline of dielectric strength is comparatively slow, and strong shelf depreciation, then dielectric strength can be made to decline very soon.
Therefore, in power equipment runs, need to detect partial discharge position and position is determined, to ensure insulation quality.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of GIS partial discharge locating device, can improve the reliability of partial discharge monitoring.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of GIS partial discharge locating device, comprise GIS housing, sensing electrode, operational amplifier, wave filter, signal amplifier and measuring instrument, the outside surface of described GIS housing has been sticked insulation film, described sensing electrode comprises medium substrate, metal patch and feeder pillar, described metal patch is sticked at the upper surface of described medium substrate and bonding with described insulation film, described feeder pillar is fixed in described medium substrate, one end of described feeder pillar is connected with described metal patch, the other end of described feeder pillar passes the lower surface of described medium substrate and is connected with the positive input of described operational amplifier, the reverse input end ground connection of described operational amplifier, the output terminal of described operational amplifier is connected with described wave filter, described wave filter connects described measuring instrument by described signal amplifier.
Be different from the situation of prior art, the beneficial effects of the utility model are: carry out partial discharge monitoring by sensing electrode to GIS device, can realize fault pre-alarming, hidden danger of fixing a breakdown in advance, thus the reliability that can improve partial discharge monitoring.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment GIS partial discharge locating device.
Fig. 2 is the structural representation of the sensing electrode of the GIS partial discharge locating device shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In the lump see Fig. 1 and Fig. 2, the GIS partial discharge locating device of the utility model embodiment comprises GIS housing 1, sensing electrode 2 operational amplifier 3, wave filter 4, signal amplifier 5 and measuring instrument 6.
The outside surface of GIS housing 1 has been sticked insulation film 11, sensing electrode 2 comprises medium substrate 21, metal patch 22 and feeder pillar 23, metal patch 22 is sticked at the upper surface of medium substrate 21 and bonding with insulation film 11, feeder pillar 23 is fixed in medium substrate 21, one end of feeder pillar 23 is connected with metal patch 22, the other end of feeder pillar 23 passes the lower surface of medium substrate 21 and is connected with the positive input of operational amplifier 3, the reverse input end ground connection of operational amplifier 3, the output terminal of operational amplifier 3 is connected with wave filter 4, wave filter 4 connects measuring instrument 6 by signal amplifier 5.
Wherein, metal patch 22 and GIS housing 1 form electric capacity, utilize this electric capacity can extract the pulse signal of shelf depreciation, and after being amplified by filtering and signal, measuring instrument 6 just can obtain local discharge signal and determine discharge position.
By the way, the GIS partial discharge locating device of the utility model embodiment carries out partial discharge monitoring by sensing electrode to GIS device, fault pre-alarming can be realized, to fix a breakdown in advance hidden danger, thus the reliability of partial discharge monitoring can be improved, there is volume little, lightweight, easy to carry, the advantages such as antijamming capability is strong.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
