Description
Technical field
The utility model relates to GIS partial discharge detection technique field, particularly relates to a kind of device for improving hand-held Partial discharge detector portability.
Background technology
Closed gas insulation in combined electric appliance is that isolating switch, disconnector, grounding switch, current transformer, voltage transformer (VT), lightning arrester, bus and outlet casing tube etc. are combined, and high-voltage charged body is sealed in and is full of SF
6in the canister of gas-insulated medium, it has good insulating property, is widely used in high voltage power transmisson system.What GIS was nearly all cut-offs, measure and excess voltage preventer is all sealed in pressure vessel, and device interior is hardly by the impact of air, and the SF used
6gas medium insulating property and arc extinction performance excellent, therefore GIS has the features such as reliable height, maintenance work is little, the time between overhauls(TBO) is longer.Although but GIS operational reliability is very high, and the GIS overall operation situation that in-site installation puts into operation is good, but because GIS is totally enclosed combined electric appliance equipment, once there be accident to occur, equipment can be opened wide than general separate type and cause even more serious consequence, and breakdown maintenance will be very complicated, repair time is long, and repair process reaches more than two weeks.
GIS have an accident many main causes there is certain burr in the mill, install in loosening appears in parts, inside has metallic impurity, insulator surface to occur dirty to move or inside has numerous reasons such as defect and causes.When there are these problems, under hyperbaric environment, device interior often shows as shelf depreciation, in various degree and under long-term electric discharge existent condition, its potential defect result in shelf depreciation and constantly occurs, apparatus insulated performance also will follow progressively deteriorated and expansion, finally cause whole apparatus insulated environment breakdown, to largely threaten the safe operation of GIS like this, thus cause equipment failure and have a power failure, bring about great losses.Along with the application of the switchgears such as GIS in electric system is more and more extensive, its safe and stable operation is most important to stablizing of safeguards system.Partial Discharge Detection grasps GIS internal operation situation, and the effective method of one of the potential insulation defect of Timeliness coverage, also by Partial Discharge Detection can be classified to inherent vice and identify, contributes to scene and analyze accident GIS.
Have developed the on-the-spot Partial Discharge Detection equipment of multiple GIS both at home and abroad, current checkout equipment main frame build used is comparatively large, and detection probe is connected with main frame by signal transmssion line; Carry ultrasonic probe by operating personnel in testing process to be at the scene placed in GIS surface of shell and to be adjacent to and to observe, detect degree of accuracy need smear silicone grease at detecting head surface for improving.In testing process, operating personnel need a hand-held probe, a hand-held silicone grease, by another people observation signal before main frame.Domesticly develop a kind of hand-held type multifunctional Partial Discharge Detection equipment at present, whole main frame is less, can grip on the other hand, gripped on the other hand by testing staff, one hand-held probe is tested, substantially increase the convenience of detection, but still need in practical operation and will be coated with silicone grease to detecting head surface, increase the complicated property of operation.And on-the-spot GIS device is more, check point is intensive, and sometimes needs to climb or bore unprecedentedly to enter for different check point, is difficult to operation when two hands divide and hold and detect main frame and probe.
Utility model content
The purpose of this utility model is exactly to solve the problem, propose a kind of device for improving hand-held Partial discharge detector portability, make operating personnel only need hand hold transducer in practical operation, liberation another hand is used for smearing silicone grease or climbing, boring in null process and hold up for climbing.
To achieve these goals, the utility model adopts following technical scheme:
For improving a device for hand-held Partial discharge detector portability, comprising: the oversheath of parcel Partial discharge detector main body, described oversheath is provided with bandage; Described oversheath is provided with high strength material outlet pipeline in the junction of Partial discharge detector's main body and probe.
Position corresponding with Partial discharge detector display screen on described oversheath adopts transparent material.
Position corresponding with Partial discharge detector body operation button on described oversheath is provided with perforate.
Described oversheath shape and close contact consistent with Partial discharge detector body shape.
Described bandage is connected with oversheath, and bandage length is adjustable.
Described bandage can be stablized and is fixed on operating personnel's arm or wrist location.
Described oversheath is removably fixed on outside Partial discharge detector's main body.
The beneficial effects of the utility model are:
The utility model structure is simple, easy to use; Can effectively improve checkout equipment portability; Make operating personnel only need hand hold transducer in practical operation, liberation another hand is used for smearing silicone grease or climbing, boring in null process and hold up for climbing.
There is protection tube in main body and signal wire junction, improve signal wire serviceable life, prevent from causing signal wire to rupture because operational issue makes wiring place repeatedly bend in actual use.
Accompanying drawing explanation
Fig. 1 is the utility model apparatus structure schematic diagram;
Wherein, 1. oversheath, 2. transparent material, 3. button operation perforate, 4. outlet pipeline.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
For improving a device for hand-held Partial discharge detector portability, as shown in Figure 1, comprise the oversheath 1 of parcel detector main body, oversheath is with bandage.
Oversheath 1 for the protection of detector main body, and is adopting transparent material 2 with main body display screen correspondence position.Button operation perforate 3 is had in body operation button relevant position.
Oversheath 1 has a high strength material outlet pipeline 4 at main frame and probe junction, for the protection of signal wire and main body wiring place, prevents from causing signal wire to rupture because operational issue makes wiring place repeatedly bend in actual use.
Bandage is connected with oversheath 1 and connects closely and length is adjustable, can firmly be tied on operating personnel's arm.
During use, detector main body is placed in oversheath, and by bandage, equipment is tied to operating personnel's left forearm, and device display screen outwardly.Pop one's head in by operating personnel on the other hand gripping, so improve detector main frame portability, liberation operating personnel hand, improves its operation flexibility.
The ultrasonic instrument for measuring partial discharge main body of certain company domestic being produced loads oversheath, and ultrasonic probe is connected with main body by signal wire, bandage is tied to operator's left forearm, the right hand hold transducer of operator, silicone grease is put in pocket on the left of operator, can take out at any time, ultrasonic Partial Discharge Detection is carried out to certain transformer station 220kV GIS.Take out silicone grease in operation at any time to carry out smearing silicone grease work, after being painted with, probe is placed in GIS housing, main body screen signal situation in observation left arm, by this kind of method, isolating switch, isolation, bus place GIS are checked comprehensively, greatly increase work efficiency, and can testing be completed by a people.
By reference to the accompanying drawings embodiment of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
