Through setting a first measurement plate and a second measurement plate on two sides of the expansion joint, a center of the first measurement plate is provided with a measurement scale possessing a telescoping function and a circular scale indication is marked on the second measurement plate so that the displacement monitoring device can accurately measure a relative displacement between units of the combined electric appliance. A guarantee is provided for safe operation of equipment.
Description
Technical field
The utility model relates to high-voltage combined electrical apparatus telescopic joint field, relates in particular to a kind of displacement monitor of high-voltage combined electrical apparatus telescopic joint.
Background technology
High-voltage combined electrical apparatus is that the air that is under the atmospheric pressure of a kind of all or part of employing gas and not adopting is as the metal enclosed switchgear of insulating medium, be filled with the SF6 insulating gas of certain pressure in high-voltage combined electrical apparatus inside, so also claim the SF6 fully closed combined electric unit.It is the high voltage distribution installation that is combined by short-circuiting device, bus, disconnector, voltage transformer (VT), current transformer, lightning arrester, 7 kinds of High-Voltage Electrical Appliances of sleeve pipe, and full name is gas insulated substation (GIS).
High-voltage combined electrical apparatus is because its floor area is little at present, and the safety coefficient advantages of higher is widely adopted.But owing to be subject to the impact of natural conditions, have certain displacement between unit and the unit, so the connecting portion between each unit is generally the telescopic joint with Telescopic.Be in operation should keep a close eye on telescopic joint change in displacement, in case combined electrical apparatus inner conductor distance changes, cause security incident.Usually we can only roughly judge change in displacement between each unit with vision, and accuracy is low, are easy to cause erroneous judgement disconnected.
The utility model content
Order of the present utility model provides a kind of displacement measuring device that can accurately measure relative displacement between each unit of combined electrical apparatus, for equipment safety operation provides guarantee.
The displacement monitor of a kind of high-voltage combined electrical apparatus telescopic joint of the present utility model, it comprises: be installed on first of telescopic joint both sides and measure plate and the second measurement plate, the surveyors' staff with Telescopic is installed at the first center of measuring plate, and second measures plate is marked with the limbus indication.
Wherein, described the first measurement plate is provided with some left sides fixed screw.
Wherein, this left side fixed screw is two.
Wherein, described the second measurement plate is provided with some right sides fixed screw.
Wherein, this right side fixed screw is two.
Wherein, surveyors' staff is fixed on the first measurement plate by a gib screw.
The beneficial effects of the utility model are, by the both sides at telescopic joint first, second is set and measures plate, the surveyors' staff with Telescopic is installed at the first center of measuring plate, second measures plate is marked with the limbus indication, this displacement monitoring device can accurately be measured the displacement measuring device of relative displacement between each unit of combined electrical apparatus like this, for equipment safety operation provides guarantee.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of instructions, and for above-mentioned and other objects, features and advantages of the present utility model can be become apparent, below especially exemplified by embodiment, and the cooperation accompanying drawing, be described in detail as follows.
Description of drawings
Fig. 1 is the synoptic diagram of the displacement monitor of high-voltage combined electrical apparatus telescopic joint.
Fig. 2 is the another synoptic diagram of the displacement monitor of high-voltage combined electrical apparatus telescopic joint.
Fig. 3 is another synoptic diagram of the displacement monitor of high-voltage combined electrical apparatus telescopic joint
Embodiment
Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, displacement monitor embodiment, structure, feature and effect thereof to according to the high-voltage combined electrical apparatus telescopic joint that the utility model proposes are described in detail as follows:
Relevant aforementioned and other technology contents of the present utility model, Characteristic can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation by embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model, yet appended graphic only provide with reference to the usefulness of explanation, the utility model is limited.
The telescopic joint of high-voltage combined electrical apparatus of the present utility model, telescopic joint mainly be absorb that the GIS bus expands with heat and contract with cold, displacement that the installation adjustment of the displacement at basic expansion joint, equipment room and earthquake and operation cause, therefore mainly be configured in the positions such as being connected of bus and each equipment, transformer inlet wire, circuit outlet.
As shown in Figure 1, the displacement monitor of high-voltage combined electrical apparatus telescopic joint comprises: be installed on first of telescopic joint both sides and measure plate 10 and the second measurement plate 20, this first, second measure plate 10,20 material is consistent with the material of high-voltage combined electrical apparatus device housings, the surveyors' staff 30 with Telescopic is installed at the first center of measuring plate 1, have some scales on the surveyors' staff 30, as shown in Figure 3; Second measures plate 20 is marked with the limbus indication, said such as Fig. 2.
Described first measures plate 10 is provided with some left sides fixed screw 11, measure plate by this left side fixed screw 11 with first and be fixed on the telescopic joint, and this left side fixed screw 11 is two; Described second measures plate 20 is provided with some right sides fixed screw 21, measure plate 20 by this right side fixed screw with second and be fixed on the telescopic joint, and this right side fixed screw 21 is two; And surveyors' staff 30 is fixed on first by gib screw 31 and measures on the plate 10.
Because the first center of measuring plate 1 has the surveyors' staff 3 of Telescopic, when telescopic joint two side apparatus generation transversal displacement, the distance of the transversal displacement of telescopic joint observes accurately by this surveyors' staff 3; Be marked with the limbus indication because second measures plate 2, when telescopic joint two side apparatus generation length travel, can measure plate 2 by second and observe accurately with the relative displacement of measuring pointer 3.
The above, only be embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
