Description
Technical field
The invention belongs to electric power system device technique field, particularly relate to the indoor rectangular bus bar fixed hardware fittings of a kind of easily detachable.
Background technology
At present in electric power system; the discharge accident such as high-tension apparatus there will be flashover, short circuit often, puncture; wherein occur that the frequency of above-mentioned accident is higher in bus bar canister or bus-bar room; trace it to its cause; main with ambient humidity change, in air contained by suspended components and have before relatively big difference (such as salt fog and other composition more complicated can suspended material) outward; simultaneously the factor such as less than normal with insulation distance is relevant, and therefore the conventional fixing gold utensil of current indoor rectangular bus bar is fixed.Fig. 1 is a kind of indoor rectangular bus bar fixed hardware fittings structure side view conventional at present.As shown in Figure 1, this indoor rectangular bus bar fixed hardware fittings comprises lower plate 10, upper plate 11, connecting screw 12 and two hold-down screws 13; Wherein lower plate 10 is oval aluminium sheet, and two ends are formed with a fixed screw through hole respectively; Connecting screw 12 is fixed on the middle part of lower plate 10, for connecting insulator; Upper plate 11 is also aluminium sheet, is positioned at above lower plate 10, and top is with rib, and two ends are formed with a fixed screw through hole corresponding with the fixed screw through hole at lower plate 10 two ends respectively; Two hold-down screws 13 are separately fixed at two fixed screw through holes lower plate 10 and upper plate 11 being positioned at the same side, are fixed by the indoor rectangular bus bar 14 between lower plate 10 and upper plate 11 thus.But there is following point in this indoor rectangular bus bar fixed hardware fittings:
1) described above, the lower plate 10 of this indoor rectangular bus bar fixed hardware fittings and upper plate 11 all adopt aluminium to make, because the mechanical strength of this material is low, pliability is poor, therefore in actual installation practice process, often there will be the situation of lower plate 10 and upper plate 11 fracture;
2) this indoor rectangular bus bar fixed hardware fittings generally adopts cast aluminium hot dip galvanizing process to process, because this technics comparing falls behind, in addition manufacturer is in cost control needs, therefore technique is not tight to check on, so inevitably leave the defects such as a large amount of wedge angles, burr on this fixing gold utensil surface, and these defects can bring very large hidden danger to the safe operation of equipment in high voltage electric field;
3) in order to fix and clamp indoor rectangular bus bar 14, hold-down screw 13 need be installed additional at the two ends of lower plate 10 and upper plate 11, simultaneously in order to meet the requirement of corresponding mechanical strength and screw installation dimension, need the length increasing lower plate 10 and upper plate 11, thus increase phase spacing L, phase spacing L=(L1-L2) × 2, through actual measurement, this phase spacing L is about 40 ~ 50mm, this just means, air insulation distance between indoor rectangular bus bar 14 decreases 40 ~ 50mm, and therefore how many discharge inception voltage reductions just well imagines;
4) high-tension apparatus can need to increase or reduce the number of plies of indoor rectangular bus bar 14 because load or ampacity change when reality uses, in this case, just need the indoor rectangular bus bar fixed hardware fittings changing different size, Master Cost so not only can be caused to increase, also increase the labour intensity of maintainer simultaneously, add interruption duration simultaneously, thus reduce electricity sales amount, and then have influence on the benefit of Utilities Electric Co..
Summary of the invention
In order to solve the problem, the object of the present invention is to provide the indoor rectangular bus bar fixed hardware fittings of a kind of easily detachable.
In order to achieve the above object, the indoor rectangular bus bar fixed hardware fittings of easily detachable provided by the invention comprises two fixed components, two spheroids, stationary body, screw and two springs; Wherein stationary body is rectangle tabular, a cuboid slot is formed with respectively to sunken inside in the middle part of two sides, and the bottom surface of slot has been recessed to form a spring providing holes downwards, be provided with screw in the middle part of the bottom surface of simultaneously stationary body, the lower end of screw is used for connecting insulator; Be provided with a spring in each spring providing holes, and the upper port place of each spring providing holes is provided with a spheroid, the lower end of spheroid is connected with spring upper end; Fixed component is connected to upper plate by upper plate, lower plate and upper and lower side, the vertical panel of end, lower plate the same side is formed, and wherein the outer end of lower plate can be inserted in the slot on stationary body, and the bottom surface of lower plate is formed with a hemispherical groove.
The upper plate length of described fixed component is greater than lower plate length, and upper plate, lower plate and vertical panel are integrally formed.
Described fixed component can be divided into plurality of specifications according to the height difference of vertical panel.
On the indoor rectangular bus bar fixed hardware fittings of described easily detachable, each parts adopt copper material to make, and bight is fillet.
Advantage and the effect of the indoor rectangular bus bar fixed hardware fittings of easily detachable provided by the invention are as follows:
1) material that on it, each parts adopt is identical with the material of copper indoor rectangular bus bar, because the ductility of copper material is relatively high compared with aluminium with pliability, so there will not be the problems such as fracture;
2) fillet process has all been carried out in the place all parts likely producing wedge angle or burr, and does not adopt hot dip galvanizing process, therefore farthest can reduce the adverse effect that wedge angle or burr bring high-tension apparatus safe operation;
3) after the material that parts adopt changes copper material into, reducing and reducing of fixing and supporting construction overall dimensions can be realized, through actual measurement, the actual size of phase spacing L is about 8 ~ 10mm, add 80% compared with the air insulation distance of traditional indoor rectangular bus bar fixed hardware fittings, thus can discharge inception voltage be improved.
4) remove and install simple and convenient, structure is simple, labour intensity is low when changing, operating efficiency is high, reduces the labour cost of unit interval.
