Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to a disconnecting switch bracket. Background Technology

[0002] High-voltage disconnect switches are important switching devices in the electrical systems of power plants and substations. They need to be used in conjunction with high-voltage circuit breakers. Traditionally, when disconnect switches are installed on poles, they are directly installed horizontally or vertically on the two crossarms of the pole. This installation method makes the disconnect switch perpendicular or parallel to the ground.

[0003] Currently, when installing disconnect switches, the length of the knife plate on the disconnect switch is limited. Therefore, the position of the disconnect switch needs to be adjusted during installation to ensure that it can meet the requirements of the connection point when the switch is closed. During installation, holes need to be drilled on the mounting bracket to determine the assembly position. Moreover, high-altitude construction is inconvenient, and the disconnect switch can easily fall when adjusting its position. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a disconnector switch bracket.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A disconnector bracket includes a mounting frame, with multiple bridging plates disposed between the inner walls of the mounting frame, and an aluminum alloy frame disposed between the tops of the mounting frame. The interior of the aluminum alloy frame is hollow, and the top is open. Three insulating sliders are slidably disposed inside the aluminum alloy frame, with the tops of the three insulating sliders extending to the top of the aluminum alloy frame. A ceramic resistor is fixed to the top of each of the three insulating sliders, and a copper sleeve is fixed to the top of each of the three ceramic resistors.

[0007] Optionally, the top of the copper sleeve located in the middle is provided with a side opening that extends to both sides, and one side of each of the other two copper sleeves is fixed with a U-shaped copper plate.

[0008] Optionally, a gate plate is provided between the two U-shaped copper plates, and the gate plate is engaged between the inner walls of the two sides of the side opening.

[0009] Optionally, an insulating guide rod is fixed between the inner walls of both sides of the aluminum alloy frame, and the three insulating sliders are slidably connected to the outer surface of the insulating guide rod.

[0010] Optionally, side grooves are provided on both outer surfaces of the aluminum alloy frame, and guide grooves penetrating into the interior of the aluminum alloy frame are provided on the bottom surface of both side grooves.

[0011] Optionally, both sides of the three insulating sliders are slidably engaged inside the guide groove, and a sliding groove is provided between the top and bottom surfaces of the guide groove.

[0012] Optionally, locking bolts are provided on both sides of the three insulating sliders, and limiting rings are fitted on the outer surfaces of the locking bolts. Two sliding plates that are slidably engaged inside the sliding grooves are fixed on the outer surfaces of the limiting rings, and one end of each locking bolt is located inside the side groove.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. In this utility model, the ceramic resistor is set on the top of the insulating slider to facilitate the adjustment of the position of the ceramic resistor inside the aluminum alloy frame. The ceramic resistor is also set in the middle so that it can support the middle part of the switch plate when the ceramic resistors at both ends close the switch plate. Especially when the length of the switch plate is large, the span generated during the connection process will also be large. At this time, the support of the ceramic resistor in the middle part for the switch plate is particularly critical, which can ensure the stability of the switch plate.

[0015] 2. In this utility model, when adjusting the position of the ceramic resistor, the ceramic resistor can first be slid to the corresponding position by sliding the insulating slider. Then, the ceramic resistor and the aluminum alloy frame can be fixed and limited by rotating the locking bolt. During the sliding process, the limiting ring can constrain the locking bolt, so that the thread end of the locking bolt is aligned with the mounting part on the insulating slider. At the same time, it can prevent the locking bolt from falling off after the insulating slider becomes loose. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, as Figure 1-4 As shown, this utility model provides a technical solution for a disconnector bracket: it includes a mounting frame 1, multiple bridging plates 2 are arranged between the inner walls of the mounting frame 1, and an aluminum alloy frame 3 is arranged between the tops of the mounting frame 1. The interior of the aluminum alloy frame 3 is hollow and the top is open. Three insulating sliders 10 are slidably arranged inside the aluminum alloy frame 3. The tops of the three insulating sliders 10 extend to the top of the aluminum alloy frame 3. Ceramic resistors 4 are fixed to the tops of the three insulating sliders 10, and copper sleeves 5 are fixed to the tops of the three ceramic resistors 4.

[0026] The overall effect of embodiment 1 is that the ceramic resistor 4 is set on the top of the insulating slider 10 to facilitate the adjustment of the position of the ceramic resistor 4 inside the aluminum alloy frame 3, and the ceramic resistor 4 is set in the middle part so that it can support the middle part of the switch plate 8 when the ceramic resistors 4 at both ends close the switch plate 8. Especially when the length of the switch plate 8 is large, the span generated during the docking process will also be large. At this time, the support of the ceramic resistor 4 in the middle part for the switch plate 8 is particularly critical, which can ensure the stability of the switch plate 8.

[0027] Example 2, as Figure 1-4As shown, the top of the copper sleeve 5 located in the middle has a side opening 7 that extends to both sides. U-shaped copper plates 6 are fixed to one side of each of the other two copper sleeves 5. A gate plate 8 is positioned between the two U-shaped copper plates 6, and the gate plate 8 engages between the inner walls of the side openings 7. Insulating guide rods 9 are fixed between the inner walls of the aluminum alloy frame 3. Three insulating sliders 10 are slidably connected to the outer surface of the insulating guide rods 9. Side grooves 16 are formed on the outer surfaces of both sides of the aluminum alloy frame 3, and through-holes are formed on the bottom surfaces of the two side grooves 16. The guide groove 11 inside the aluminum alloy frame 3 is provided with three insulating sliders 10 on both sides corresponding to the guide groove 11. The guide groove 11 has a sliding groove 12 between the top and bottom surfaces. Locking bolts 15 are provided on both sides of the three insulating sliders 10. Limiting rings 13 are fitted on the outer surface of the multiple locking bolts 15. Two sliding plates 14 are fixed on the outer surface of the multiple limiting rings 13 and are slidably engaged in the sliding groove 12. One end of the multiple locking bolts 15 is located inside the side groove 16.

[0028] The effect achieved by the entire embodiment 2 is that when adjusting the position of the ceramic resistor 4, the ceramic resistor 4 can first be slid to the corresponding position by sliding the insulating slider 10, and then the ceramic resistor 4 and the aluminum alloy frame 3 can be fixed and limited by rotating the locking bolt 15. During the sliding process, the locking bolt 15 can be constrained by the limiting ring 13, so that the thread end of the locking bolt 15 is aligned with the mounting part on the insulating slider 10, and at the same time, it can prevent the locking bolt 15 from falling off after the insulating slider 10 is loose.

[0029] Working principle: The ceramic resistor 4 is placed on the top of the insulating slider 10 to facilitate the adjustment of the position of the ceramic resistor 4 inside the aluminum alloy frame 3. The ceramic resistor 4 is also placed in the middle so that it can support the middle part of the switch plate 8 when the ceramic resistors at both ends close the switch plate 8. When adjusting the position of the ceramic resistor 4, the ceramic resistor 4 can be slid to the corresponding position by sliding the insulating slider 10. Then, the ceramic resistor 4 can be fixed and limited between the aluminum alloy frame 3 by rotating the locking bolt 15. During the sliding process, the locking bolt 15 can be constrained by the limiting ring 13, so that the thread end of the locking bolt 15 can be aligned with the mounting part on the insulating slider 10. At the same time, it can prevent the locking bolt 15 from falling off after the insulating slider 10 loosens.
