DETAILED DESCRIPTION
[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0021] See also Figure 1-Figure 3 The present embodiment provides a substation knife switch dual confirmation sensor mounting bracket with strong compatibility, including two ear brackets 1, two T-shaped brackets 7, a first combination bracket 8 and a second combination bracket 9. The two ear brackets 1, the two T-shaped brackets 7, the first combination bracket 8 and the second combination bracket 9 form a mounting bracket 13 as a whole. The mounting bracket 13 is mounted on the knife switch device of the substation as a whole. The shape of the ear bracket 1 is L-shaped, such as Figure 1 As shown, one end of the first combined bracket 8 and one end of the second combined bracket 9 are slidably connected, the vertical brackets of the two T-shaped brackets 7 are slidably connected to the other end of the first combined bracket 8 and the other end of the second combined bracket 9, respectively, the two ear brackets 1 are slidably set on the lateral brackets of the two T-shaped brackets 7, and the vertical brackets of the two T-shaped brackets 7 are set on the switch equipment of the substation. The sliding between the first combined bracket 8, the second combined bracket 9, the ear bracket 1 and the T-shaped bracket 7 forms a spatial rectangular coordinate system, so that the installation bracket 13 can adjust the distance along the spatial rectangular coordinate system as a whole;
[0022] The ear bracket 1, the first combined bracket 8 and the second combined bracket 9 are all L-shaped brackets. The first combined bracket 8 and the second combined bracket 9 are first combined into a whole. Both ends of the combined whole of the first combined bracket 8 and the second combined bracket 9 are connected to T-shaped brackets 7, and the two ear brackets 1 are respectively slidably arranged on the lateral brackets of the two T-shaped brackets 7. Figure 1 As shown, the transverse bracket of the first combined bracket 8 and the transverse bracket of the second combined bracket 9 are combined together, and the transverse bracket of the first combined bracket 8 and the transverse bracket of the second combined bracket 9 can slide, so as to adjust the overall length between the first combined bracket 8 and the second combined bracket 9. After the first combined bracket 8 and the second combined bracket 9 are adjusted to a suitable position, the first combined bracket 8 and the second combined bracket 9 are fixed by the second screw 10. After the ear bracket 1 slides to a suitable position on the transverse bracket of the T-shaped bracket 7, it is limited by the first screw 3. The first screw 3 is an M3*8 cross pan head screw, and the second screw 10 is an M4*10 cross pan head screw. The cross pan head screw is easy to tighten and disassemble, the notch is cross-shaped, and a bayonet connection is adopted to avoid sliding, Sliding, damage, etc., and the vertical bracket of the T-shaped bracket 7 and the vertical bracket of the first combined bracket 8 and the vertical bracket of the second combined bracket 9 are fixed together by the cooperation of the first nut 4, the spring washer 5 and the flat washer 6. The vertical bracket of the T-shaped bracket 7, the vertical bracket of the first combined bracket 8, and the vertical bracket of the second combined bracket 9 are all provided with a plurality of screw holes, and the plurality here is greater than or equal to three. When the first nut 4 penetrates through one of the groups of screw holes on the vertical bracket of the T-shaped bracket 7, the vertical bracket of the first combined bracket 8, and the vertical bracket of the second combined bracket 9 to fix the three, the vertical bracket of the T-shaped bracket 7 can be moved up and down along the vertical bracket of the first combined bracket 8 and the vertical bracket of the second combined bracket 9 to adjust the height by penetrating the different screw holes by the first screw 3;
[0023] In addition, sliding between the transverse bracket of the first combined bracket 8 and the transverse bracket of the second combined bracket 9 can achieve adjustment in the X-axis direction, sliding between the ear bracket 1 and the transverse bracket of the T-shaped bracket 7 can achieve adjustment in the Y-axis direction, and sliding between the vertical bracket of the T-shaped bracket 7 and the vertical bracket of the first combined bracket 8 and the vertical bracket of the second combined bracket 9 can achieve adjustment in the Z-axis direction. The X-axis, Y-axis and Z-axis here are only to represent the three directions of the spatial rectangular coordinates. The specific naming of the X-axis, Y-axis and Z-axis is not fixed. For the convenience of description, one of the naming methods is selected here.
[0024] The existing knife switch double confirmation sensor mounting bracket 13 is mostly non-standard design, and the corresponding mounting bracket 13 is designed according to different manufacturers. Since each knife switch is manufactured by a different manufacturer, many positions, the width of the beam 14, the moving distance of the detection point and other related installation data will be different, and the substation knife switch double confirmation sensor mounting bracket 13 generally requires on-site investigation before production. However, during the investigation, in order not to affect the use of the substation, power outages are generally not allowed. The surveyor cannot do any action beyond the safety range for the knife switch equipment on site, and the measurement can only be within the safe distance. However, the knife switch double confirmation project requires three-way three-way detection in many places, that is, all three phases must be detected, and the detection position has exceeded the safe distance. The on-site surveyor cannot obtain accurate size information through measuring tools, and can only estimate by visual estimation, which may cause a large error in the bracket. In addition, generally, the knife switch equipment in the older substation is basically not only manufactured by one manufacturer, some have multiple manufacturers, and some even have more than a dozen manufacturers. In this way, the design difficulty of the bracket will be very large, and due to the incompatibility of the bracket, the design time is greatly extended, and the processing cost is greatly increased.
[0025] In order to solve the above problems, in this embodiment, by using two ear brackets 1, two T-brackets 7, a first combined bracket 8 and a second combined bracket 9 as a mounting bracket 13 as a whole, the mounting bracket 13 is installed as a whole on the knife switch equipment of the substation, and one end of the first combined bracket 8 and one end of the second combined bracket 9 are slidably connected, the vertical brackets of the two T-brackets 7 are slidably connected with the other end of the first combined bracket 8 and the other end of the second combined bracket 9, respectively, the two ear brackets 1 are slidably set on the transverse brackets of the two T-brackets 7, and the vertical brackets of the two T-brackets 7 are set on the knife switch equipment of the substation. The sliding between the first combined bracket 8, the second combined bracket 9, the ear bracket 1 and the T-bracket 7 forms a spatial rectangular coordinate system, the sliding between the transverse bracket of the first combined bracket 8 and the transverse bracket of the second combined bracket 9 can realize the adjustment in the X-axis direction, and the sliding between the ear bracket 1 and the transverse bracket of the T-bracket 7 can realize the adjustment in the Y-axis direction, so that the mounting bracket 13 is adapted to the knife switch equipment of most manufacturers, which solves the problem that the existing substation knife switch double confirmation sensor mounting bracket 13 cannot adapt to the knife switch equipment of most manufacturers and has poor compatibility.
[0026] In order to further improve the compatibility of the substation knife switch dual confirmation sensor mounting bracket 13, while the mounting bracket 13 can be adjusted, if the position of the dual confirmation sensor 2 can also be adjusted, then the compatibility will be better. In this regard, in one embodiment, a slide groove for adjusting the installation position of the dual confirmation sensor 2 is provided on the ear bracket 1. After the ear bracket 1 is adjusted to a suitable position, the dual confirmation sensor 2 does not fully reach a suitable detection position due to an error. At this time, the dual confirmation sensor 2 can be slid in the slide groove again to adjust the dual confirmation sensor 2 to a suitable detection position.
[0027] Since the voltage station is located outdoors in addition to indoors, in order to ensure that the mounting bracket 13 can ensure ultra-high strength while also overcoming the harsh outdoor environment, in one embodiment, the ear bracket 1, the T-shaped bracket 7, the first combined bracket 8 and the second combined bracket 9 are all made of stainless steel, and the mounting bracket 13 composed of the ear bracket 1, the T-shaped bracket 7, the first combined bracket 8 and the second combined bracket 9 is made of 304 stainless steel as a whole, which can ensure ultra-high strength while also overcoming the harsh outdoor environment.
[0028] In order to ensure that the mounting bracket 13 has good compatibility as a whole, the stability is also required to be very good. In this regard, in one embodiment, the substation knife switch equipment includes two cross beams 14 and two longitudinal beams. The mounting bracket 13 is arranged on the cross beam 14. The two cross beams 14 and the two longitudinal beams are connected to form a rectangular support frame. A porcelain bottle base 12 is arranged on the four corners of the rectangular support frame. The porcelain bottle base 12 is provided with an isolating switch 11. A crank arm 15 is installed on the porcelain bottle base 12. The crank arms 15 of the porcelain bottle bases 12 opposite to each other on the two cross beams 14 are connected by the same horizontal connecting rod 16. The two T-shaped brackets 7 and the cross beam 14 are connected by bolts. The T-shaped bracket 7 and the cross beam 14 are fixed as one body, and the bolts are used to fix the T-shaped bracket 7 and the cross beam 14. On the one hand, it is ensured that the mounting bracket 13 as a whole can be firmly fixed to the cross beam 14, and on the other hand, the mounting bracket 13 as a whole can be disassembled from the cross beam 14, which is convenient for later maintenance. The substation knife switch equipment used here is the commercially available substation knife switch equipment. In order to facilitate the fixing position of the mounting bracket 13 and how the mounting bracket 13 is fixed to the substation knife switch equipment, it is mentioned that the substation knife switch equipment includes the cross beam 14, the longitudinal beam, the porcelain bottle base 12, the isolating switch 11 and the crank arm 15, which does not mean that the substation knife switch equipment is only These structures, and the crossbeams, longitudinal beams, porcelain bottle bases, crank arms and isolating switches on this substation knife switch equipment are only partially drawn in the diagram. This substation knife switch equipment is three-phase, so the crossbeams, longitudinal beams, porcelain bottle bases, crank arms and isolating switches are not just shown in the figure, and this application is mainly for the design of the mounting bracket structure. Therefore, the remaining components are possessed by commercially available substation knife switch equipment, and will not be elaborated here. They are not further drawn in the accompanying drawings. The monitoring point of the double confirmation sensor 2 is located directly below the connection point between the crank arm 15 and the horizontal connecting rod 16, that is, the connection point of the crank arm 15. The sensor mounting bracket 13 is fixed On the beam 14 of the knife switch device, the position of the sensor detection is located at the connection point of the crank arm 15, which is located below the porcelain bottle. It is the position that can most directly reflect whether the knife switch is in place, and all three-phase transformers have this position, so this detection point is selected. This detection point will move with the movement of the crank arm 15 and the horizontal connecting rod 16. The points of the open and closed positions are generally symmetrically distributed on the left and right sides of the beam 14, so the installation bracket 13 needs to be able to detect the positions on the left and right sides of the beam 14 of each phase, so that the installation bracket 13 of the present application is more compatible than the installation bracket 13 in the prior art.
[0029] It is worth mentioning that if the fixing between the mounting bracket 13 and the cross beam 14 of the knife gate device is fixed by bolts or screws after drilling holes in the cross beam 14, then a fire ticket is required, and only professional licensed personnel can operate it, which will greatly reduce the construction efficiency. In order to ensure that no fire ticket is required, the mounting bracket 13 and the cross beam 14 of the knife gate device can also be fixed without loss. In this regard, in one embodiment, the bolts used between the two T-shaped brackets 7 and the cross beam 14 are long bolts, and the number of bolts is greater than or equal to two. The two bolts and the two T-shaped brackets 7 form a closed area, and the cross beam 14 is located in the closed area. Here, the two bolts are formed with the bottom of the vertical bracket of the two T-shaped brackets 7. The closed area is formed, the crossbeam 14 is clamped in the closed area, and then the bolts are tightened. At the same time, the T-shaped bracket 7 is fixed to the crossbeam 14 again with the hexagon socket set screw 18. The purpose of using the hexagon socket set screw 18 is to expose the fixing point of the T-shaped bracket 7 and the crossbeam 14 to the outside, and the fixing point of the T-shaped bracket 7 and the crossbeam 14 is relatively narrow. The hexagon socket set screw 18 can be used in narrow occasions, ensuring that assembly and maintenance are very convenient. At the same time, the hexagon socket set screw 18 can sink the entire nut into the inside of the workpiece, which can maintain the flatness and aesthetics of the workpiece surface, and ensure that the fixing effect between the T-shaped bracket 7 and the crossbeam 14 is better, so that the T-shaped bracket 7 and the crossbeam 14 can be fixed. Figure 3 As shown, the bolts used to fix the T-shaped bracket 7 and the cross beam 14 are long hexagonal bolts 17. The purpose of using the long hexagonal bolts 17 is that, considering the possible sliding between the T-shaped bracket 7 and the cross beam 14, the long hexagonal bolts 17 can increase the area of action of the torque, prevent sliding, and improve the fastening effect.
