Description

Technical Field

[0001] The utility model relates to the technical field of insulating brackets, in particular to an insulating bracket for power transmission and transformation equipment. Background Art

[0002] Power transmission and transformation equipment is the core part of the power system. They are responsible for the transmission and transformation of electric energy, ensuring that electric energy can be safely and efficiently transmitted from power plants to end users. The insulation bracket of power transmission and transformation equipment is an important component used in power systems to provide mechanical support and maintain electrical insulation. It is used to support and protect transmission cables.

[0003] In the Chinese utility model with publication number CN217692585U, an insulating bracket for power transmission and transformation equipment is disclosed. It can adjust the spacing between each insulating support plate according to the thickness of the cable after being laid flat, so it is convenient to make corresponding adjustments according to the cable wiring situation. By extending the component, the use length of the insulating support plate can be conveniently adjusted according to the laying length of the cable. It is flexible to use and has a wide range of applications.

[0004] Although the device can adjust the use length of the insulating support plate by extending the assembly, the cable is positioned only by the groove on the insulating support plate, which will cause the cable to move on the insulating support plate, resulting in the cable sheath being damaged due to the contact between adjacent cables, and then causing line short circuit or open circuit problems. To this end, we provide an insulating support for power transmission and transformation equipment to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-4 As shown, the utility model provides a technical solution: an insulating bracket for power transmission and transformation equipment, comprising a fixing bracket 1, a connecting assembly and at least two insulating plates 3.

[0027] The fixing frame 1 is provided with positioning blocks 2 arranged at equal distances. The fixing frame 1 is provided with two groups of fixing holes 4. The cross section of the fixing frame 1 is concave. The fixing holes 4 are located on the inner wall of the fixing frame 1. The fixing frame 1 can be fixed by installing expansion bolts in the fixing holes 4.

[0028] Each insulating plate 3 is provided with a positioning slot 13 that matches the positioning block 2. The insulating plate 3 can be inserted into the positioning block 2 through the positioning slot 13, so that the insulating plate 3 can be preliminarily positioned. The insulating plate 3 is provided with a slide groove 8, and a slider 9 is slidably connected in the slide groove 8. The cross-section of the slide groove 8 is cross-shaped, which enables the slider 9 to slide in the slide groove 8 without causing the slider 9 to slide out of the slide groove 8.

[0029] The slider 9 is fixedly connected with a slide rod 14 , and the slide rod 14 is provided with an insulating partition 12 that can be lifted and lowered. The insulating partition 12 is provided with a limiting component for limiting the slider 9 in the slide groove 8 .

[0030] The limiting assembly includes a positioning groove 10 opened on the insulating plate 3 and a positioning plug plate 11 fixedly connected to the insulating partition 12. The positioning groove 10 is connected to the slide groove 8, and the positioning plug plate 11 matches the positioning groove 10. When the insulating partition 12 drives the positioning plug plate 11 to be pulled out from the inside of the positioning groove 10, the limiting of the slider 9 in the slide groove 8 can be released, and the limiting of the insulating partition 12 can be completed by inserting the positioning plug plate 11 into the positioning groove 10, so that the distance between adjacent insulating partitions 12 can be adjusted.

[0031] The limiting assembly also includes a cavity 16 opened in the insulating partition 12, an adapter hole 15 opened in the positioning plug plate 11, and a linkage plate 17 fixedly connected to the slide rod 14. The top end of the slide rod 14 passes through the adapter hole 15 and the insulating partition 12 in sequence and extends into the cavity 16, so that the insulating partition 12 can rely on the cavity 16 to make the insulating partition 12 rise and fall and slide on the slide rod 14.

[0032] A return spring 18 is sleeved on the slide rod 14, and the two ends of the return spring 18 respectively abut against the linkage plate 17 and the inner bottom wall of the cavity 16. The linkage plate 17 is supported by the elasticity of the return spring 18 itself, thereby ensuring the stability of the positioning plug plate 11 in the positioning groove 10, and compressing the return spring 18 through the linkage plate 17 when the insulating partition 12 moves upward, which can release the external tension on the insulating partition 12 and enable the return spring 18 to drive the insulating partition 12 to quickly reset.

[0033] The connecting assembly is arranged on the fixing frame 1, and is used for placing the insulating plate 3 on the positioning block 2. The connecting assembly includes a through hole 5 opened on the fixing frame 1, a screw hole 6 opened on the positioning block 2, and a fixing bolt 7. A through hole matching the screw hole 6 is opened on the insulating plate 3, and one end of the fixing bolt 7 passes through the through hole 5 and the through hole in sequence and is threadedly connected to the screw hole 6.

[0034] When the insulating plate 3 is inserted into the positioning block 2 through the positioning slot 13, the fixing bolt 7 can be passed through the through hole 5 and the through hole thread and installed in the screw hole 6, so as to fix the insulating plate 3 on the positioning block 2. By installing the insulating plate 3 on the positioning block 2 at different positions, the distance between adjacent insulating plates 3 can be adjusted.

[0035] Working principle: When the spacing between adjacent insulating plates 3 needs to be adjusted, first, the fixing bolts 7 on the current insulating plate 3 are screwed out to release the limit on the positioning block 2 of the insulating plate 3, and then, the insulating plate 3 is installed on another positioning block 2 through the positioning card slot 13 to adjust the spacing between adjacent insulating plates 3. Finally, the fixing bolts 7 are passed through the through holes 5 and the through-hole threads and installed in the screw holes 6, so that the insulating plate 3 is fixed on the positioning block 2, and the spacing between adjacent insulating plates 3 can be adjusted. When the spacing between adjacent insulating partitions 12 needs to be adjusted, first, the insulating partition 12 is pulled upward, so that the insulating partition 12 can drive the positioning plug 11 to be pulled out from the inside of the positioning slot 10, thereby releasing the insulation board 3. In addition to the limitation of the slider 9 in the slide groove 8, the linkage plate 17 will compress the reset spring 18 at this time, and then drive the slider 9 to move in the slide groove 8 through the insulating partition 12, and move the insulating partition 12 to a suitable position. Finally, release the insulating partition 12. Under the action of the elasticity of the reset spring 18 itself, the insulating partition 12 can drive the positioning plug 11 to be inserted into the interior of the positioning groove 10, thereby fixing the insulating partition 12 and the slider 9, and enabling multiple insulating partitions 12 to form wire-laying spaces of different sizes on the insulating plate 3, so as to adaptively clamp and position the cable according to its thickness, thereby avoiding displacement of the cable on the insulating plate 3, thereby effectively reducing the wear of the cable sheath caused by friction between adjacent cables.
