Description

Technical Field

[0001] The invention belongs to the technical field of cable lightning arrester installation, and in particular relates to a lightning arrester that can be quickly replaced and an installation method thereof. Background Art

[0002] Cable lightning arrester is a device used to protect cable systems from lightning and overvoltage damage. Its principle is to guide lightning or overvoltage energy through electrical discharge paths, safely into the ground, and avoid damage to cable equipment. Cable lightning arrester usually consists of voltage limiter, discharge device, etc., which can quickly respond to high voltage transients in the power grid and suppress them to a safe range, thereby effectively protecting the power system from lightning or transient overvoltage.

[0003] The Chinese patent application number is 202110101009.1. It discloses a lightning arrester installation structure that is easy to install, including a mounting frame and a lightning arrester body. The outer side of the lightning arrester body is fixedly connected to an insulating frame with one end passing through the mounting frame. Two sleeves are fixedly installed on the right side of the mounting frame. The interiors of the two sleeves are fixedly installed with tension springs with one end extending to the inside of the insulating frame. A clearance hole is provided on the top of the insulating frame. The top of the mounting frame is movably connected to a pin with one end passing through the clearance hole and extending to the outside of the mounting frame. The lightning arrester installation structure that is easy to install has the advantage of easy installation, and solves the problem that in the bracket-type installation method, bolts are generally used to lock the insulating bracket equipped with the lightning arrester with the metal bracket for installation. However, this installation method requires the user to carry auxiliary workpieces such as wrenches with him, which is not convenient enough for aerial work and has low efficiency.

[0004] When installing a lightning arrester with bolts, the installation is not only troublesome, but if the lightning arrester is damaged, it is also troublesome to replace it. At the same time, for some equipment that can quickly replace lightning arresters, the connection stability of the lightning arrester is usually not guaranteed, resulting in circuit disconnection problems, making the installation unstable. In addition, how to ensure smoothness and avoid jamming when quickly switching lightning arresters is also a research focus. Summary of the invention

[0005] In order to solve the deficiencies existing in the prior art, the present invention provides a lightning arrester that can be quickly replaced. Through the cooperation of the switching frame and the frame body, the present invention can not only facilitate the installation of the lightning arrester body, but also quickly replace the damaged lightning arrester body; through the cooperation of the first limiting mechanism and the second limiting mechanism, the present invention can not only ensure that the lightning arrester body can be successfully switched without jamming when sliding the switching frame, but also improve the contact stability of the lightning arrester body and avoid the occurrence of unstable connection disconnection; the present invention can also elastically limit the lightning arrester body at multiple angles, improve the buffering performance of the lightning arrester body, and further improve the installation stability of the lightning arrester body.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A lightning arrester that can be quickly replaced, including a frame body. A connecting plate is vertically slidably connected to both the top and bottom of the frame body. An electrical connection block is installed on the connecting plate for connecting the circuit. A switching frame is horizontally slidably connected inside the frame body. Multiple lightning arrester bodies are inserted into the switching frame. The conductive columns at the upper and lower ends of the lightning arrester body are in contact with the corresponding electrical connection blocks.

[0008] Further, the frame body includes a square frame. Fixed blocks are fixedly provided around the top and bottom of the square frame. A sliding hole is penetrated through the fixed block. Sliding rods are fixedly provided around the connecting plate. The sliding rods are slidably connected to the corresponding sliding holes. A return spring is sleeved on the sliding rod. The return spring is located between the connecting plate and the fixed block. A limiting protrusion is provided at one end of the sliding rod. A set of insertion chutes are horizontally fixed above and below the inside of the square frame. The outside of the switching frame is slidably connected to the insertion chutes.

[0009] Further, a plurality of connection ports are evenly opened on the connecting plate. The connection ports are correspondingly arranged with the adjacent conductive columns. The electrical connection blocks are fixedly installed on the connection ports. A positioning groove is penetrated through the connecting plate between adjacent connection ports. Diagonal panels are fixedly connected to both ends of the connecting plate.

[0010] Furthermore, the switching frame includes two upper and lower insertion plates. The four sides of the two insertion plates are fixedly connected by fixing rods. A plurality of insertion slots are evenly penetrated through the insertion plates. The insertion slots communicate with one side of the insertion plates. Positioning strips are fixedly provided on both sides of the insertion plates where the insertion slots are located.

[0011] Furthermore, the number of insertion slots = the number of lightning arrester bodies + 1.

[0012] Furthermore, a slideway is provided at the inner bottom of the insertion slot, and a first limiting mechanism is arranged on the slideway. The first limiting mechanism includes a first sliding rod slidably connected to the slideway of the insertion slot. One end of the first sliding rod is fixedly connected to a first curved panel. A first limiting spring is sleeved on the first sliding rod, and two ends of the first limiting spring are respectively fixedly connected to the insertion slot and the first curved panel.

[0013] Furthermore, second slideways are symmetrically arranged on the inner side wall of the connection port. A second limiting mechanism is arranged on the second slideways. The second limiting mechanism includes a second curved panel for conducting electricity. One convex side of the second curved panel is fixedly connected to a second sliding rod, and the second sliding rod is slidably connected to the corresponding second slideway. A second limiting spring is sleeved on the second sliding rod, and two ends of the second limiting spring are respectively fixedly connected to the connection port and the second curved panel. The top end of the second curved panel is fixedly connected to a metal slider.

[0014] Furthermore, a chute is provided at the bottom of the electrical connection block. The connecting metal slider is located in the chute and is slidably connected to the chute. A wiring column is fixedly connected to the top of the electrical connection block, and the wiring column is electrically connected to the corresponding circuit.

[0015] Furthermore, handles are fixedly arranged at both ends of the switching frame; dust-proof nets are fixedly arranged on both sides of the square frame.

[0016] The present invention also claims to protect an installation method of using the above-mentioned lightning arrester that can be quickly replaced, including the following steps:

[0017] S1. When operating normally, a group of insertion slots are in an idle state. Insert a new lightning arrester body into the idle insertion slot for standby.

[0018] S2. When one lightning arrester body at the end far from the idle insertion slot is damaged, push the switching frame to install the new lightning arrester body, and the damaged lightning arrester body is pushed out and removed. The switching frame waits for the next switch.

[0019] S3. When the lightning arrester body at the end close to the idle insertion slot or the lightning arrester body in the middle of the frame body is damaged, pull the switching frame to pull out the damaged lightning arrester body, then replace the new lightning arrester body with the damaged lightning arrester body, and finally push the switching frame for installation.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) Through the cooperation of the switching frame and the frame body, the present invention can not only facilitate the installation of the arrester body, but also quickly replace the damaged arrester body. Specifically, the arrester body is flexibly inserted through multiple sets of insertion slots on the switching frame, and the connection is realized by pressing the conductive columns of the arrester body with the upper and lower connecting plates. Under the limit of multiple positioning columns on the corresponding positioning slots, the arrester body can be effectively limited and fixed, thus facilitating the installation of the arrester body and eliminating the need for one-by-one connection through bolts, etc. At the same time, in the present application, through the lateral sliding of the switching frame inside the square frame, during the sliding process, the positioning strips of the upper and lower insertion plates of the switching frame push the corresponding inclined panels and positioning slots, so that the upper and lower connecting plates are pushed apart, and the connection plates release the limit on the arrester body. At this time, by continuing to slide the switching frame, the arrester body can be moved, so that the damaged arrester body can be quickly removed from the frame body and a new arrester body can be replaced at the same time, realizing the quick replacement of the damaged arrester body.

[0022] (2) Through the cooperation of the first limiting mechanism and the second limiting mechanism, the present invention can not only ensure the successful switching of the arrester body without jamming when sliding the switching frame, but also improve the contact stability of the arrester body and avoid the occurrence of unstable connection and disconnection. Specifically, when it is necessary to switch the arrester body, by sliding the switching frame, at this time, the two insertion plates need to be pushed apart after the positioning strips move horizontally. Through the structural design of the second limiting mechanism, when the switching frame slides, the arrester body can be horizontally stressed and squeeze one side of the second curved panel. Under the action of the second limiting spring and the second sliding rod, the arrester body can successfully achieve horizontal movement, and the positioning strips on the switched switching frame can push apart the two insertion plates. After being pushed apart, the conductive columns of the arrester body are disengaged from the limit of the second limiting mechanism. At this time, the first limiting mechanism comes into play. Through the elastic force of the first limiting spring, the first curved panel is prompted to push the arrester body to slide on the insertion slot, realizing the dislocation of the arrester body and the connection port. Finally, after the subsequent sliding of the switching frame to switch to the correct position, by pushing the arrester body and squeezing the first curved panel of the first limiting mechanism, after the conductive columns are finally aligned with the two second curved panels, the successful switching of the arrester body is achieved through the reset of the connecting plate, avoiding the problem that the conductive columns are misaligned and stuck under the second limiting mechanism due to the direct horizontal movement of the arrester body. At the same time, since the conductive columns are elastically limited and connected by the two second limiting mechanisms after successful installation, the contact stability of the arrester body is improved, and the occurrence of unstable connection and disconnection is avoided.

[0023] (3) Through the cooperation of the first limiting mechanism and the second limiting mechanism, the present invention can also elastically limit the arrester body at multiple angles, improving the buffering performance of the arrester body. And under the elastic limitation of the two connecting plates, when vibration occurs, the arrester body can be effectively shock-absorbed and protected, further improving the installation stability of the arrester body.

[0036] Embodiment

[0037] As Figures 1 to 8 shown, a lightning arrester that can be quickly replaced includes a frame body 100. A connecting plate 400 is vertically slidably connected to both the top and bottom of the frame body 100. An electrical connection block 500 is installed on the connecting plate 400 for connecting a circuit. A switching frame 200 is horizontally slidably connected inside the frame body 100. A plurality of lightning arrester bodies 300 are inserted into the switching frame 200. The conductive columns 310 at the upper and lower ends of the lightning arrester body 300 are in contact with the corresponding electrical connection blocks 500.

[0038] Through the cooperation of the switching frame 200 and the frame body 100, the present invention can not only facilitate the installation of the lightning arrester body 300, but also quickly replace the damaged lightning arrester body 100. A detailed description will be given later.

[0039] It is worth noting that the electrical connection blocks 500 above and below are respectively connected to the cable and the ground, so as to quickly conduct and introduce to the ground during overvoltage, thereby protecting equipment such as cables from being damaged. This is a mature existing technology and will not be described in detail here.

[0040] Further, the frame body 100 includes a square frame 120. Fixed blocks 130 are fixedly provided around the top and bottom of the square frame 120. A sliding hole is penetrated through the fixed block 130. Slide bars 420 are fixedly provided around the connecting plate 400. The slide bars 420 are slidably connected to the corresponding sliding holes. A return spring 421 is sleeved on the slide bar 420. The return spring 421 is located between the connecting plate 400 and the fixed block 130. A limit protrusion is provided at one end of the slide bar 420. A group of insertion chutes 140 are horizontally fixed above and below the inside of the square frame 120. The outside of the switching frame 200 is slidably connected to the insertion chutes 140.

[0041] The switching frame 200 slides horizontally on the insertion chute 140, and the upper and lower connecting plates 400 press and limit the switching frame 200 through the action of the sliding rod 420 and the return spring 421.

[0042] It should be noted that the frame body 100 of the present invention will also be installed and fixed to a wire column or the like through an external bracket, which is a conventional setting and will not be described in detail herein.

[0043] Furthermore, a plurality of connection ports 440 are uniformly opened on the connecting plate 400, and the connection ports 440 are correspondingly arranged with adjacent conductive columns 310; the electrical connection blocks 500 are fixedly installed on the connection ports 440; positioning grooves 430 are penetrated through the connecting plate 400 between adjacent connection ports 440; inclined panels 410 are fixedly connected to both ends of the connecting plate 400. The inclined panels 410 facilitate the switching frame 200 to push open the upper and lower connecting plates 400.

[0044] Even further, the switching frame 200 includes upper and lower insertion plates 210, and the peripheries of the two insertion plates 210 are jointly fixed by fixing rods 220; a plurality of insertion slots 250 are uniformly penetrated through the insertion plates 210, and the insertion slots 250 communicate with one side of the insertion plates 210; positioning strips 240 are fixedly provided on the insertion plates 210 on both sides of the insertion slots 250. By the positioning strips 240, the inclined panels 410 and the positioning grooves 430 are squeezed, so as to realize the pushing open of the two connecting plates 400.

[0045] The present invention flexibly inserts the arrester body 300 through multiple groups of insertion slots 250 on the switching frame 200, and realizes the connection by using the upper and lower connecting plates 400 to press the conductive columns 310 of the arrester body 300. Under the limitation of a plurality of positioning columns 240 on the corresponding positioning grooves 430, the arrester body 300 can be effectively limited and fixed, so as to facilitate the installation of the arrester body 100, thus eliminating the need to connect one by one through bolts, etc.; at the same time, in the present application, through the horizontal sliding of the switching frame 200 inside the square frame 120, during the sliding process, the positioning strips 240 of the upper and lower insertion plates 210 of the switching frame 200 push the corresponding inclined panels 410 and positioning grooves 430, so that the upper and lower connecting plates 400 are pushed open, and the connecting plates 400 release the limitation on the arrester body 300. At this time, by continuing to slide the switching frame 200, the position of the arrester body 300 can be moved, so that the damaged arrester body 300 can be quickly removed from the frame body 100 and a new arrester body 300 can be simultaneously replaced, realizing the quick replacement of the damaged arrester body 100.

[0046] Even further, the number of the insertion slots 250 = the number of the arrester bodies 300 + 1.

[0047] Through the structural design that the number of the insertion slots 250 is one more than the number of the arrester bodies 300, it can not only ensure that there is always an extra insertion slot 250 for placing the spare arrester body 300, but also can quickly perform the replacement operation when only one arrester body 300 is damaged, and the replacement is convenient without disassembling and installing the equipment.

[0048] Furthermore, a slideway is opened at the inner bottom of the insertion slot 250, and a first limiting mechanism 600 is arranged on the slideway. The first limiting mechanism 600 includes a first sliding rod 610 slidably connected to the slideway of the insertion slot 250. One end of the first sliding rod 610 is fixedly connected to a first curved panel 620. A first limiting spring 630 is sleeved on the first sliding rod 610, and two ends of the first limiting spring 630 are respectively fixedly connected to the insertion slot 250 and the first curved panel 620.

[0049] Through the structural design of the first limiting mechanism 600, the arrester body 300 on the insertion slot 250 will be pushed away by the first curved panel 620 when it is in a non-limited state, so that the conductive column 310 is misaligned with the connection port 440.

[0050] Furthermore, second slideways 441 are symmetrically opened on the inner side wall of the connection port 440, and a second limiting mechanism 700 is arranged on the second slideways 441. The second limiting mechanism 700 includes a second curved panel 710 for conducting electricity. One convex side of the second curved panel 710 is fixedly connected to a second sliding rod 720. The second sliding rod 720 is slidably connected to the corresponding second slideway 441. A second limiting spring 730 is sleeved on the second sliding rod 720, and two ends of the second limiting spring 730 are respectively fixedly connected to the connection port 440 and the second curved panel 710. The top end of the second curved panel 710 is fixedly connected to a metal slider 740.

[0051] Through the structural design of the two second limiting mechanisms 700, the second curved panel 710 for conducting electricity is always elastically abutted against the corresponding conductive column 310.

[0052] Furthermore, a chute is opened at the bottom of the electrical connection block 500, and the connecting metal slider 740 is located in the chute and slidably connected to the chute. A wiring column 510 is fixedly connected to the top of the electrical connection block 500, and the wiring column 510 is electrically connected to the corresponding circuit.

[0053] Through the cooperation of the first limiting mechanism 600 and the second limiting mechanism 700, the present invention can not only ensure the successful switching of the arrester body 300 without jamming when sliding the switching frame 200, but also improve the contact stability of the arrester body 300 and avoid the occurrence of unstable connection disconnection. Specifically, when it is necessary to switch the arrester body 300, through the sliding switching frame 200, at this time, the two plugging plates 210 need to be pushed open after the positioning strip 240 moves horizontally. Through the structural design of the second limiting mechanism 700, when the switching frame 200 slides, the arrester body 300 can be horizontally stressed and squeeze one side of the second curved panel 710. Under the action of the second limiting spring 730 and the second sliding rod 720, the arrester body 300 can successfully achieve horizontal movement. Only after the positioning strip 240 on the moved switching frame 200 pushes open the two plugging plates 210 can the subsequent switching be realized. After being pushed open, the conductive column 310 of the arrester body 300 is disengaged from the limit of the second limiting mechanism 700. At this time, the first limiting mechanism 600 comes into play. Through the elastic force of the first limiting spring 630, the first curved panel 620 is urged to push the arrester body 300 to slide on the plugging slot 250, realizing the dislocation of the arrester body 300 and the connection port 440. Finally, after the subsequent switching frame 200 slides to the good position, by pushing the arrester body 300 and squeezing the first curved panel 620 of the first limiting mechanism 600, after the conductive column 310 is finally aligned with the two second curved panels 710, the switching of the arrester body 300 is successfully realized through the reset of the connecting plate 400, avoiding the problem that the conductive column 310 is misaligned and stuck under the second limiting mechanism 700 due to the direct horizontal movement of the arrester body 300. At the same time, since the conductive column 310 is elastically limited and connected by the two second limiting mechanisms 700 after successful installation, the contact stability of the arrester body 300 is improved, and the occurrence of unstable connection disconnection is avoided.

[0054] Through the cooperation of the first limiting mechanism 600 and the second limiting mechanism 700, the present invention can also elastically limit the arrester body 300 at multiple angles, improving the buffering performance of the arrester body 300. And under the elastic limit of the two connecting plates 400, when vibration occurs, the arrester body 300 can be effectively shock-absorbed and protected, further improving the installation stability of the arrester body 300.

[0055] Furthermore, handles 230 are fixedly provided at both ends of the switching frame 200; dust-proof nets 110 are fixedly provided on both sides of the square frame 120. The sliding of the switching frame 200 is conveniently controlled through the handles 230, and the dust-proof performance is improved through the dust-proof nets 110.

[0056] It should be noted that after the dust-proof net 110 is set, it is not conducive to the subsequent sliding of the arrester body 300 on the insertion slot 250. The problem of the arrester body 300 sliding on the insertion slot 250 can be solved by conventionally setting the pores of the dust-proof net 110 and by means of a long-strip tool. This is a conventional setting and will not be described in detail here.

[0057] An installation method of an arrester using the above-mentioned arrester that can be quickly replaced includes the following steps:

[0058] S1. When operating normally, one set of insertion slots 250 is in an idle state. Insert the new arrester body 300 into the idle insertion slot 250 for standby.

[0059] S2. When one arrester body 300 at the end far from the idle insertion slot 250 is damaged, push the switching frame 200 to install the new arrester body 300, and the damaged arrester body 300 is pushed out and removed. The switching frame 200 waits for the next switching.

[0060] S3. When the arrester body 300 at the end close to the idle insertion slot 250 or the arrester body 300 in the middle of the frame body 100 is damaged, pull the switching frame 200 to pull out the damaged arrester body 300, then replace the new arrester body 300 with the damaged arrester body 300, and finally push the switching frame 200 for installation.

[0061] Through this installation method, the present invention can quickly perform replacement operations when only one arrester body 300 is damaged, without cumbersome disassembly and installation.

[0062] It should be noted that when installing or replacing the arrester of the present invention, a power-off operation of the external circuit is required. This is a conventional setting and will not be described in detail here.

[0063] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several improvements and transformations can be made, and these all belong to the protection scope of the present invention.
