Description

Technical Field

[0001] The utility model relates to the technical field of application of substation lightning arresters, in particular to a lightning arrester positioning and installation component based on an intelligent substation. Background Art

[0002] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltages and limit the follow current time. It is usually connected between a live wire and the ground, in parallel with the protected equipment. When the overvoltage value reaches the specified operating voltage, the lightning arrester immediately operates, conducts charges, limits the overvoltage amplitude, and protects the equipment insulation; after the voltage value returns to normal, the lightning arrester quickly returns to its original state to ensure normal power supply of the system.

[0003] When the existing lightning arrester is installed and fixed, generally a fixed mounting part needs to be connected to its bottom for bolt connection and fixation. When installing and fixing the position of the lightning arrester, it is necessary to connect the required cables. Different connection methods are required for installations at different positions, which results in the inability of traditional mounting parts to be adjusted adaptively, thereby reducing the convenience during installation. Moreover, when connecting and fixing the cables, tools are needed to bolt-lock the cable joints, which makes it difficult for workers to operate during high-altitude operations, thus reducing the connection and installation efficiency. Therefore, the present utility model proposes a lightning arrester positioning and installation component based on an intelligent substation. Summary of the Utility Model

Specific embodiments

[0029] The following will elaborate on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0030] As Figures 1 - 3 shown, the positioning and installation assembly of the arrester based on the intelligent substation includes an arrester body 100. The bottom of the arrester body 100 is bolted to an installation structure 200. The installation structure 200 includes a fixing member 201 and an adjusting member 202 that is slidably adjusted therewith. The end face of the adjusting member 202 is fixedly connected with a slider 202a. The slider 202a is slidably connected to the inside of a sliding groove 201b opened at the bottom of the fixing member 201. An installation notch 202c is opened on the end face of the adjusting member 202, facilitating bolt connection and fixation when installing the adjusting member 202 through the installation notch 202c, and also facilitating the fixing member 201 to quickly slide onto the slider 202a through the sliding groove 201b at the bottom for installation and fixation later. A limiting connection groove 202b is opened at the top of the slider 202a. A tightening bolt 201a is threadedly connected through the top of the fixing member 201 near the end face. The end face of the tightening bolt 201a abuts against the inside of the limiting connection groove 202b, facilitating the fixing member 201 to carry the arrester body 100 and insert it onto the slider 202a, and at the same time using the tightening bolt 201a to lock the fixing member 201 on the fixed slider 202a. An opening is opened on the end face of the adjusting member 202, and an anti-slip pad 202d is adhered to the inside of the opening and is located on both sides of the two installation notches 202c respectively, facilitating anti-slip setting through the anti-slip pad 202d when installing the adjusting member 202 to prevent shaking during installation. The end face of the adjusting member 202 is connected and fixed to the equipment of the substation through bolts. The fixing member 201 is sleeved on the outer wall of the arrester body 100 near the bottom and is in abutting contact with it through an insulating sleeve 101 sleeved on the bottom of the arrester body 100.

[0031] As Figures 4 - 6As shown in the figure, a connection component 300 is bolted to the top of the arrester body 100. The connection component 300 includes an L-shaped frame 301 bolted to the top of the arrester body 100. A positioning hole 302 is formed in the side wall of the L-shaped frame 301 near the top. A limiting boss 303 is arranged on the outer wall of the positioning hole 302. Slide bars 304 are symmetrically and fixedly connected to the outer wall of the side wall of the L-shaped frame 301 near the outer wall of the positioning hole 302. Springs 305 are wrapped around the outer walls of the two slide bars 304. The clamping frames slide on the two slide bars 304 near the end faces respectively and are in abutting contact with the end faces of the two springs 305. It is convenient to utilize the elasticity of the spring 305 to make the clamping frames on the slide bars 304 press and fix the cable connector to prevent it from falling off. A clamping frame is slidably connected to the two slide bars 304. The clamping frame includes a sliding plate 307. Elastic members 308 are symmetrically and fixedly connected to the side wall of the sliding plate 307 near the end face. Blocks 309 are fixedly connected to the end faces of the two elastic members 308. The two blocks 309 are respectively inserted into two clamping grooves formed in the limiting boss 303. At the same time, a plurality of anti-slip grooves 309a are formed on the same side. It is convenient to relatively squeeze the elastic members 308 connected by the blocks 309 when installing and fixing the cable connector, so as to conveniently sleeved the cable connector on the limiting boss 303, and then loosen the block 309 and clamp and fix it. Limiting caps 306 are fixedly connected to the end faces of the two slide bars 304. The elastic members 308 connected by the blocks 309 are relatively squeezed, so as to conveniently sleeved the cable connector on the limiting boss 303. Then, the block 309 drives the sliding plate 307 to slide on the slide bar 304 to squeeze the spring 305. Finally, the block 309 is loosened and the cable connector is clamped and fixed by the restoring elasticity of the spring 305.

[0032] When the utility model is in use, first, the adjusting member 202 is fixed on the external equipment of the substation through the installation slot 202c, and anti-slip setting is carried out under the action of the anti-slip pad 202d. Then, the fixing member 201 is bolted to the bottom of the arrester body 100, slides into the slider 202a through the chute 201b at the bottom of the fixing member 201, and then the fixing member 201 is locked on the fixed slider 202a through the tightening bolt 201a. Then, the elastic members 308 connected by the blocks 309 are relatively squeezed, so as to conveniently sleeved the cable connector on the limiting boss 303. Then, the block 309 drives the sliding plate 307 to slide on the slide bar 304 to squeeze the spring 305. Finally, the block 309 is loosened and the cable connector is clamped and fixed by the restoring elasticity of the spring 305.
