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 in the prior art, the present invention provides a lightning arrester that can be quickly replaced. The present invention can facilitate the installation of the lightning arrester body and quickly replace the damaged lightning arrester body through the cooperation of the switching frame and the frame body; the present invention can ensure that the lightning arrester body can be successfully switched without getting stuck when the sliding switching frame is slid, and at the same time can improve the contact stability of the lightning arrester body to avoid the occurrence of unstable connection and disconnection; the present invention can also elastically limit the lightning arrester body at multiple angles, thereby improving the buffering performance of the lightning arrester body and further improving the installation stability of the lightning arrester body.

[0006] In order to achieve the above object, the present invention adopts the following technical solution: A lightning arrester that can be quickly replaced includes a frame, the top and bottom of the frame are vertically slidably connected to a connecting plate, and an electrical connection block is installed on the connecting plate for connecting the circuit; the interior of the frame is horizontally slidably connected to a switching frame, and a plurality of lightning arrester bodies are plugged into the switching frame; the conductive columns at the upper and lower ends of the lightning arrester bodies abut against the corresponding electrical connection blocks.

[0007] Furthermore, the frame body includes a square frame, and fixed blocks are fixed around the top and bottom of the square frame, and sliding holes are penetrated on the fixed blocks; sliding rods are fixed around the connecting plate, and the sliding rods are slidably connected with the corresponding sliding holes; a reset spring is sleeved on the sliding rod, and the reset spring is located between the connecting plate and the fixed block; a limiting protrusion is provided at one end of the sliding rod; a group of plug-in slide grooves are horizontally fixed on the upper and lower parts of the interior of the square frame, and the outer side of the switching frame is slidably connected with the plug-in slide grooves.

[0008] Furthermore, the connection plate is evenly provided with a plurality of connection ports, which are arranged corresponding to adjacent conductive columns; the electrical connection block is fixedly mounted on the connection port; positioning grooves are penetrated through the connection plate between adjacent connection ports; and both ends of the connection plate are fixedly connected to the inclined plate.

[0009] Furthermore, the switching frame includes two upper and lower plug-in boards, which are fixed together by fixing rods on all sides; multiple plug-in slots are evenly arranged on the plug-in boards, and the plug-in slots are connected to one side of the plug-in boards; positioning strips are fixed on the plug-in boards on both sides of the plug-in slots.

[0010] Furthermore, the number of plug-in slots=the number of arrester bodies+1.

[0011] Furthermore, a slide is provided at the inner bottom of the plug-in slot, and a first limiting mechanism is provided on the slide. The first limiting mechanism includes a first sliding rod slidably connected to the slide of the plug-in slot, one end of the first sliding rod is fixedly connected to the first curved plate, and a first limiting spring is sleeved on the first sliding rod, and both ends of the first limiting spring are respectively fixedly connected to the plug-in slot and the first curved plate.

[0012] Furthermore, the inner side wall of the connecting port is symmetrically provided with a second slide, and the second slide is provided with a second limiting mechanism, and the second limiting mechanism includes a second curved plate for conduction, and the convex side of the second curved plate is fixedly connected to a second sliding rod, and the second sliding rod is slidably connected to the corresponding second slide; a second limiting spring is sleeved on the second sliding rod, and the two ends of the second limiting spring are respectively fixedly connected to the connecting port and the second curved plate; and the top of the second curved plate is fixedly connected to a metal slider.

[0013] Furthermore, a slide groove is provided at the bottom of the electrical connection block, and a connecting metal slider is located in the slide groove and is slidably connected to the slide groove; a terminal is fixedly connected to the top of the electrical connection block, and the terminal is electrically connected to the corresponding circuit.

[0014] Furthermore, handles are fixedly provided at both ends of the switching frame; and dustproof nets are fixedly provided at both sides of the square frame.

[0015] The present invention also claims a method for installing the above-mentioned quick-replaceable arrester, comprising the following steps: S1. During normal operation, a group of slots are idle, and a new arrester body is inserted into the idle slots for standby use; S2. When a lightning arrester body far from one end of the idle plug-in slot is damaged, the switch frame is pushed to install a new lightning arrester body, the damaged lightning arrester body is pushed out and removed, and the switch frame waits for the next switch; S3. When the arrester body near one end of the idle plug-in slot or the arrester body in the middle of the frame is damaged, pull the switching frame to pull out the damaged arrester body, then replace the damaged arrester body with a new one, and finally push the switching frame to install it.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention can facilitate the installation of the arrester body and quickly replace the damaged arrester body through the cooperation between the switching frame and the frame body; specifically, the arrester body is flexibly plugged in through the multiple groups of plug-in slots on the switching frame, and the upper and lower connecting plates are used to press the conductive columns of the arrester body to achieve connection. When multiple positioning columns are limited on the corresponding positioning slots, the arrester body can be effectively limited and fixed, thereby facilitating the installation of the arrester body, and there is no need to connect one by one through bolts or the like; at the same time, the present application slides the switching frame horizontally inside the square frame, and during the sliding process, the positioning bars of the upper and lower plug-in plates of the switching frame push the corresponding inclined plates and the positioning slots, so that the upper and lower connecting plates are squeezed apart, and the connecting plates release the limit on the arrester body. At this time, the switching frame is continued to slide, so that the arrester body can be moved, so that the damaged arrester body can be quickly moved out of the frame and the new arrester body can be replaced at the same time, so that the damaged arrester body can be quickly replaced.

[0017] (2) The present invention can ensure that the arrester body can be successfully switched without getting stuck when the sliding switching frame is used, and can also improve the contact stability of the arrester body and avoid the occurrence of unstable connection and disconnection. Specifically, when the arrester body needs to be switched, the switching frame is slid. At this time, the two plug-in boards need to be squeezed apart after the positioning bar moves horizontally. The structural design of the second limiting mechanism allows the arrester body to be subjected to horizontal force when the switching frame slides, and squeezes the second curved plate on one side. Under the action of the second limiting spring and the second sliding rod, the arrester body can successfully achieve horizontal movement. The positioning bar on the moving switching frame can squeeze the two plug-in boards apart. After being squeezed apart, the conductive column of the arrester body is detached. The second limiting mechanism is limited, and the first limiting mechanism takes effect at this time. The elastic force of the first limiting spring prompts the first curved plate to push the lightning arrester body to slide on the plug-in slot, so as to achieve the misalignment of the lightning arrester body and the connecting port. Finally, after the subsequent sliding switching frame switches the position, the lightning arrester body is pushed and the first curved plate of the first limiting mechanism is squeezed, so that the conductive column is finally aligned with the two second curved plates. The lightning arrester body is successfully switched by resetting the connecting plate, avoiding the problem of the conductive column being misaligned and stuck under the second limiting mechanism due to the direct lateral movement of the lightning arrester body. At the same time, after the installation is successful, the conductive column is elastically limited and connected by the two second limiting mechanisms at the same time, which improves the contact stability of the lightning arrester body and avoids the occurrence of unstable connection and disconnection.

[0018] (3) The present invention can elastically limit the arrester body at multiple angles through the cooperation of the first limiting mechanism and the second limiting mechanism, thereby improving the buffering performance of the arrester body. In addition, under the elastic limitation of the two connecting plates, the arrester body can be effectively shock-absorbed and protected when vibration occurs, further improving the installation stability of the arrester body.

Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0022] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0023] Example

[0024] like Figure 1 to Figure 8 As shown, a lightning arrester that can be quickly replaced includes a frame 100, the top and bottom of the frame 100 are vertically slidably connected to a connecting plate 400, and an electrical connection block 500 is installed on the connecting plate 400 for connecting the circuit; the interior of the frame 100 is horizontally slidably connected to a switching frame 200, and a plurality of lightning arrester bodies 300 are plugged into the switching frame 200; the conductive columns 310 at the upper and lower ends of the lightning arrester bodies 300 abut against the corresponding electrical connection blocks 500.

[0025] The present invention can facilitate the installation of the arrester body 300 and quickly replace the damaged arrester body 100 by cooperating with the switching frame 200 and the frame body 100; this will be described in detail later.

[0026] It is worth noting that the upper and lower electrical connection blocks 500 correspond to the connection cables and the ground respectively, so as to achieve rapid conduction into the ground when overvoltage occurs, thereby protecting cables and other equipment from damage. This is an existing mature technology and will not be described in detail here.

[0027] Furthermore, the frame body 100 includes a square frame 120, and fixed blocks 130 are fixed around the top and bottom of the square frame 120, and sliding holes are penetrated on the fixed blocks 130; sliding rods 420 are fixed around the connecting plate 400, and the sliding rods 420 are slidably connected with the corresponding sliding holes; a reset spring 421 is sleeved on the sliding rod 420, and the reset spring 421 is located between the connecting plate 400 and the fixed block 130; a limiting protrusion is provided at one end of the sliding rod 420; a group of plug-in slide grooves 140 are horizontally fixed on the upper and lower parts of the square frame 120, and the outer side of the switching frame 200 is slidably connected with the plug-in slide grooves 140.

[0028] The switch frame 200 slides horizontally on the plug-in slide groove 140 , and the upper and lower connecting plates 400 press and limit the switch frame 200 through the action of the slide rod 420 and the return spring 421 .

[0029] It is worth noting that the frame 100 of the present invention is also installed and fixed by means of external brackets and electric poles, etc. This is a conventional setting and will not be described in detail here.

[0030] Furthermore, the connection plate 400 is evenly provided with a plurality of connection ports 440, and the connection ports 440 are arranged corresponding to adjacent conductive pillars 310; the electrical connection block 500 is fixedly mounted on the connection ports 440; a positioning groove 430 is provided through the connection plate 400 between adjacent connection ports 440; and both ends of the connection plate 400 are fixedly connected to the inclined plate 410. The inclined plate 410 facilitates the switching frame 200 to squeeze the upper and lower connection plates 400 apart.

[0031] Furthermore, the switching frame 200 includes two upper and lower plug-in boards 210, and the four sides of the two plug-in boards 210 are fixed together by fixing rods 220; a plurality of plug-in slots 250 are evenly arranged on the plug-in board 210, and the plug-in slots 250 are connected to one side of the plug-in board 210; and positioning bars 240 are fixed on the plug-in board 210 located on both sides of the plug-in slots 250. The positioning bars 240 are used to squeeze the inclined plate 410 and the positioning slots 430 so that the two connecting plates 400 are squeezed apart.

[0032] The present invention flexibly plugs the arrester body 300 through multiple groups of plug-in slots 250 on the switching frame 200, and uses the upper and lower connecting plates 400 to press the conductive columns 310 of the arrester body 300 to achieve connection. When multiple positioning columns 240 are limited on the corresponding positioning slots 430, the arrester body 300 can be effectively limited and fixed, thereby facilitating the installation of the arrester body 100, thereby eliminating the need for one-by-one connection through bolts, etc.; at the same time, the present application slides the switching frame 200 horizontally inside the square frame 120 During the sliding process, the positioning bars 240 of the upper and lower plug-in boards 210 of the switching frame 200 push the corresponding inclined panels 410 and the positioning grooves 430, so that the upper and lower connecting plates 400 are squeezed apart, and the connecting plates 400 release the limit on the arrester body 300. At this time, continue to slide the switching frame 200 to move the arrester body 300, so that the damaged arrester body 300 can be quickly moved out of the frame 100 and the new arrester body 300 can be replaced at the same time, so as to realize the rapid replacement of the damaged arrester body 100.

[0033] Furthermore, the number of the plug-in slots 250 = the number of the arrester bodies 300 + 1.

[0034] The present invention adopts a structural design in which the number of plug-in slots 250 is one more than the number of lightning arrester bodies 300, thereby ensuring that there is always a redundant plug-in slot 250 for placing a spare lightning arrester body 300, and at the same time, it can also be quickly replaced when only one lightning arrester body 300 is damaged, and the replacement is convenient without disassembling the installation equipment.

[0035] Furthermore, a slide is provided at the inner bottom of the plug-in slot 250, and a first limiting mechanism 600 is provided on the slide. The first limiting mechanism 600 includes a first slide rod 610 slidably connected to the slide of the plug-in slot 250, and one end of the first slide rod 610 is fixedly connected to the first curved panel 620. A first limiting spring 630 is sleeved on the first slide rod 610, and both ends of the first limiting spring 630 are respectively fixedly connected to the plug-in slot 250 and the first curved panel 620.

[0036] Through the structural design of the first limiting mechanism 600 , the arrester body 300 on the plug slot 250 can be pushed away by the first curved plate 620 in a non-limiting state, so that the conductive column 310 and the connecting port 440 are misaligned.

[0037] Furthermore, the inner wall of the connecting port 440 is symmetrically provided with a second slideway 441, and the second slideway 441 is provided with a second limiting mechanism 700, and the second limiting mechanism 700 includes a second curved plate 710 for conduction, and the convex side of the second curved plate 710 is fixedly connected to the second slide rod 720, and the second slide rod 720 is slidably connected to the corresponding second slideway 441; a second limiting spring 730 is sleeved on the second slide rod 720, and the two ends of the second limiting spring 730 are respectively fixedly connected to the connecting port 440 and the second curved plate 710; the top of the second curved plate 710 is fixedly connected to the metal slider 740.

[0038] Through the structural design of the two second limiting mechanisms 700 , the second curved plate 710 for conducting electricity is always in elastic contact with the corresponding conductive column 310 .

[0039] Furthermore, a slide groove is provided at the bottom of the electrical connection block 500, and the connecting metal slider 740 is located in the slide groove and is slidably connected to the slide groove; the top of the electrical connection block 500 is fixedly connected to the terminal post 510, and the terminal post 510 is electrically connected to the corresponding circuit.

[0040] The cooperation of the first limiting mechanism 600 and the second limiting mechanism 700 of the present invention can not only ensure that the arrester body 300 can be successfully switched without being stuck when the sliding switching frame 200 is slid, but also improve the contact stability of the arrester body 300 and avoid the occurrence of unstable connection and disconnection; specifically, when the arrester body 300 needs to be switched, the switching frame 200 is slid. At this time, the two plug-in boards 210 need to be squeezed apart after the positioning bar 240 moves horizontally. The structural design of the second limiting mechanism 700 enables the arrester body 300 to be subjected to horizontal force when the switching frame 200 slides, and squeezes the second curved plate 710 on one side. Under the action of the second limiting spring 730 and the second sliding rod 720, the arrester body 300 can successfully achieve horizontal movement, and the positioning bar 240 on the moving switching frame 200 can squeeze the two plug-in boards 210 apart to achieve subsequent switching; after squeezing apart, the conductive column 310 of the arrester body 300 is released The first limit mechanism 600 is limited by the second limit mechanism 700. At this time, the first limit mechanism 600 takes effect, and the elastic force of the first limit spring 630 causes the first curved plate 620 to push the lightning arrester body 300 to slide on the plug-in slot 250, so as to achieve the misalignment of the lightning arrester body 300 and the connecting port 440. Finally, after the subsequent sliding switching of the switching frame 200, the first curved plate 620 of the first limit mechanism 600 is pushed to the lightning arrester body 300 and squeezed to make the conductive column 310 finally aligned with the two second curved plates 710. Then, the lightning arrester body 300 is successfully switched by resetting the connecting plate 400, thereby avoiding the problem that the lightning arrester body 300 directly moves horizontally and causes the conductive column 310 to be misaligned and stuck under the second limit mechanism 700. At the same time, after the installation is successful, the conductive column 310 is elastically limited and connected by the two second limit mechanisms 700 at the same time, thereby improving the contact stability of the lightning arrester body 300 and avoiding the situation that the connection is unstable and disconnected.

[0041] The present invention can elastically limit the arrester body 300 at multiple angles through the cooperation of the first limiting mechanism 600 and the second limiting mechanism 700, thereby improving the buffering performance of the arrester body 300. In addition, under the elastic limitation of the two connecting plates 400, the arrester body 300 can be effectively shock-absorbing and protected when vibration occurs, thereby further improving the installation stability of the arrester body 300.

[0042] Furthermore, handles 230 are fixedly provided at both ends of the switching frame 200, and dustproof nets 110 are fixedly provided at both sides of the square frame 120. The handles 230 facilitate the sliding control of the switching frame 200, and the dustproof nets 110 improve the dustproof performance.

[0043] It is worth noting that the setting of the dustproof net 110 is not conducive to the subsequent control of the lightning arrester body 300 to slide on the plug-in slot 250. The problem of the lightning arrester body 300 sliding on the plug-in slot 250 can be solved by conventionally setting the pores of the dustproof net 110 and using long strip tools. This is a conventional setting and is not described in detail here.

[0044] A method for installing the quick-replaceable arrester comprises the following steps: S1. During normal operation, a group of plug-in slots 250 are in an idle state, and a new lightning arrester body 300 is inserted into the idle plug-in slots 250 for standby use; S2. When a lightning arrester body 300 away from one end of the idle plug-in slot 250 is damaged, the switch frame 200 is pushed to install a new lightning arrester body 300, the damaged lightning arrester body 300 is pushed out and removed, and the switch frame 200 waits for the next switch; S3. When the arrester body 300 near one end of the idle plug-in slot 250 or the arrester body 300 in the middle of the frame 100 is damaged, pull the switching frame 200 to pull out the damaged arrester body 300, then replace the damaged arrester body 300 with a new one, and finally push the switching frame 200 for installation.

[0045] Through this installation method, the present invention can quickly perform a replacement operation when only one arrester body 300 is damaged, without the need for cumbersome disassembly and installation.

[0046] It is worth noting that the present invention requires powering off the external circuit when installing or replacing the arrester, which is a conventional setting and will not be described in detail here.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
