Detailed Description
It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.
As shown in fig. 1, the butt joint dust-proof device of the high-voltage electrical equipment of the transformer substation is formed by combining three triangular prisms 1 up and down, the cross sections of the triangular prisms 1 are isosceles triangles, the triangular prisms 1 are vertically arranged, the tops of the lower triangular prisms 1 are connected with the positions of triangles formed by the median lines of the upper triangular prisms 1 in the adjacent triangular prisms 1, the triangular prisms 1 are provided with through holes, the cross sections of the through holes of the lowermost triangular prism 4 are circular, the through holes of the triangular prisms 1 are communicated, and the arcs of the inner wall surfaces of the through holes of the triangular prisms 1 which are more than the second last are excessive.
In the invention, the butt joint device is formed by overlapping the triangular prisms 1, the side lengths of the triangular prisms 1 are sequentially increased from bottom to top, and the top of the lower triangular prism 1 is connected with the position of a triangle formed by a median line at the bottom of the upper triangular prism 1. Therefore, the high-voltage bushing above the positioning device can easily enter the butting device, the problem that in the existing positioning process, a plurality of people need to judge and cooperate through eyes and feelings to realize alignment is solved, and the time is long in the aligning and positioning process, so that the entering of dust or dust is influenced.
The reason why the triangular prism 1 is used in the present invention is: the triangle-shaped that the median line of triangular prism 1 formed can first guarantee that the diameter of opening diminishes gradually, the diameter of compound high-voltage tube, the second is the alignment butt joint end that guarantees that high-voltage bushing can be accurate, and the third is, the triangle-shaped that the median line formed is intermediate position, and the diameter on each limit of triangle-shaped is the same, helps forming the structure of symmetry, and the circular opening of the triangular prism of below is the interior circle of triangle-shaped, the accurate location of formation that can be convenient.
Triangle-shaped that the median line of triangular prism 1 formed meets with triangular prism 1 of below, and when high-voltage bushing got into in the opening, can slide into the position of centre all the time along the opening, the preparation process of whole device also is fairly simple, is favorable to forming accurate location simultaneously, has brought the convenience for the preparation process, only need aim at triangle-shaped interface position can, avoid because the error leads to the device about the structure inaccurate, the difference of precision is brought to the location.
The inside of triangular prism 1 is the slope setting to for the arc is excessive, the opening top of the triangular prism more than the penultimate triangular prism 5 is the arc limit that the limit of median line triangle-shaped outwards expanded formation. The shape of opening top cross section for compriseing three arc limits, the bottom of opening is the same with the shape of next triangular prism top opening, is favorable to smooth gliding of high-voltage bushing.
As shown in FIG. 2, it can be seen that the ports of the triangular prisms are communicated up and down and gradually reduced in diameter. The function of guiding is formed. When the high-voltage bushing enters the circular through opening 3 in the triangular prism at the bottom, the high-voltage bushing vertically falls down, and finally the conducting rod in the high-voltage bushing accurately enters the center position of the butt joint end. The inside wall of circular opening 3 and high-voltage bushing's lateral wall laminating. The high-pressure high pipe can be prevented from moving.
In the process of butt joint, hoisting equipment can be used in an auxiliary mode.
The butt joint dustproof device has a dustproof effect, the butt joint position is protected by installing the device, and the high-voltage bushing is not exposed to the external environment in the butt joint process after entering.
Set up gas inlet 8 on the lateral wall of below triangular prism 4, gas inlet 8 departments set up the adsorbed layer, and gas inlet 8 helps in the balancing unit and the effect of device external pressure, and when high-voltage bushing did not insert in the opening, the air passed through in the 8 entering openings of gas inlet, after the adsorbed layer, filtered the dust, in the clean air entering opening, prevented that external dust from getting into from the opening at top.
The cylinder 6 is sleeved outside the bottommost triangular prism 4. The phenomenon that the triangular prism below is unstable and inclined in the alignment process of the high-voltage bushing is prevented. The cylinder has the function of balancing force.
The cone 7 is established to the bottom outside cover of cylinder 6, and cone 7 has the effect of further balancing power, prevents that high-voltage bushing from touching the inside wall of triangular prism at the in-process of aiming at, has solved the unstable problem that leads to the triangular prism.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
