Description

Technical Field

[0001] The present application relates to the technical field of power supply lightning arresters, and in particular to a conveniently replaceable power supply lightning arrester. Background Art

[0002] Power lightning arresters are widely used in distribution boxes. Their main function is to quickly reduce impedance through varistors, gas discharge tubes and other components in the case of instantaneous overvoltage caused by lightning, and guide lightning current to flow safely into the earth, thereby protecting the power system from damage. With the increase in modern industrial and civil electrical equipment, the requirements for power lightning protection are also getting higher and higher, especially for large facilities and important places, reliable power lightning protection measures are particularly important.

[0003] At present, common power supply lightning arresters are all one-time designs. Once struck by lightning, they lose their protective capabilities and need to be replaced in time to ensure the safety of the system. The main reason is that when the lightning arrester drains high voltage and high current to the ground, its internal components will be damaged, resulting in it being unable to play an effective protective role again. If you continue to use a lightning arrester that has been damaged, it may cause the equipment to be damaged by lightning. Not only will it fail to protect the equipment, but it will cause greater damage to the equipment.

[0004] In order to solve the above problems, lightning protection modules are usually designed to be pluggable. When the lightning arrester is aged or damaged, the lightning protection performance of the system can be restored by simply replacing a new lightning protection module to achieve continuous protection of the power distribution system. Although the pluggable lightning protection module is easy to replace, the close fit between the lightning protection module and the base leads to greater resistance during the disassembly and assembly process, making the operation inconvenient. Especially in emergency situations, this inconvenience may delay maintenance time and affect the safe operation of the entire power system. Therefore, how to further optimize the design of the lightning protection module so that it has good protection performance and can be replaced quickly and conveniently when necessary has become a technical problem that needs to be solved urgently. Summary of the invention

This locking method is simple, reliable, and easy to operate and maintain.

[0021] Preferably, the connector is slidably arranged on the base, and the spring tenon is fixedly connected to the connector; when the spring tenon moves and separates from the engaging portion, the connector is also separated from the plug.

[0022] By adopting the above technical solution, after the spring latch is separated from the engaging portion, the connector is also separated from the plug synchronously, thereby reducing the resistance encountered by the plug when it is retracted into the housing, thereby facilitating the removal of the lightning protection module.

DETAILED DESCRIPTION

[0040] The following is combined with the accompanying drawings Figures 1 to 5 The present invention is described in further detail. Example 1

[0041] The embodiment of the present application provides a conveniently replaceable power supply lightning arrester, referring to Figure 1 and Figure 2 , including a base 1 and a lightning protection module 2. A mounting groove 11 for mounting the lightning protection module 2 is provided on the base 1, and the lightning protection module 2 is loosely matched with the mounting groove 11. The lightning protection module 2 also includes a shell 21 and a plug 22, the plug 22 is electrically connected to the internal components, and two plugs 22 are provided and are respectively located on two opposite side walls of the shell 21. A storage hole 23 is provided on the shell 21, and the plug 22 is slidably arranged in the storage hole 23 and can be extended to the outside of the shell 21, so as to realize the extension and retraction of the plug 22. Plug holes 12 are provided on the opposite side walls of the mounting groove 11, and a connector 13 is provided in the plug hole 12, and the connector 13 is used to be electrically connected to an external circuit. The plug 22 can be inserted into the plug hole 12 and connected to the connector 13. The lightning protection module 2 also includes an operating mechanism 24, and the operating mechanism 24 includes an operating rod, one end of the operating rod is connected to the plug 22, and the other end extends to the outside of the shell 21.

[0042] During specific use, the lightning protection module 2 is inserted into the mounting groove 11. Since the lightning protection module 2 and the mounting groove 11 are clearance-matched, there is almost no insertion resistance. The operating rod is used to push the plug 22 to extend and retract. Through the operating rod, the plug 22 is inserted into the jack 12 and matched with the connector 13. The housing 21 has high stability due to the restriction of the matching between the plug 22 and the jack 12, and is not easy to fall off from the mounting groove 11, so that normal operation can be guaranteed. When disassembling the lightning protection module 2, it is only necessary to retract the plug 22 into the housing 21 through the operating rod to complete the separation of the lightning protection module 2 and the base 1. Since the lightning protection module 2 is subject to less resistance, the lightning protection module 2 can be directly removed.

[0043] In order to ensure the installation of other components inside the lightning protection module 2, a partition can be installed inside the outer shell 21 to form an interlayer space between the partition and the side wall of the outer shell 21. The operating mechanism 24 is arranged in the interlayer space, and other components are directly installed in other areas inside the outer shell 21 to avoid mutual interference between the operating mechanism 24 and other components, thereby further ensuring the normal operation of the lightning protection module 2. Example 2

[0044] Reference Figure 2 , based on Example 1, the embodiment of the present application further optimizes the structure of the plug 22 and the connector 13. Specifically, the plug 22 includes a bottom plate 221, a metal conductive sheet 222 and a bearing sheet 223. The bottom plate 221 is slidably matched with the receiving hole 23, and the operating rod is connected to the bottom plate 221 and pushes the bottom plate 221 to move in the receiving hole 23. Two bearing sheets 223 are provided and are fixedly connected to the bottom plate 221, and the metal conductive sheet 222 is provided between the two bearing sheets 223 and is fixedly connected to the bottom plate 221.

[0045] Therefore, when the plug 22 is inserted into the socket 12, the supporting sheet 223 will cooperate with the socket 12 and limit the movement of the shell 21. The supporting sheet 223 is made of a relatively strong insulating material, such as a plastic plate, and has a relatively high load-bearing performance, which effectively ensures the connection strength between the shell 21 and the base 1, thereby ensuring the stability of the lightning protection module 2 and the stability of the connection state between the metal conductive sheet 222 and the connector 13.

[0046] Furthermore, the length of the carrier sheet 223 is greater than the length of the metal conductive sheet 222, and when the metal conductive sheet 222 is retracted into the housing 21, the end of the carrier sheet 223 is located outside the housing 21 and forms a guide portion. A guide groove 14 that matches the guide portion is provided on the side wall of the mounting slot 11. This design improves the accuracy and stability of the docking between the plug 22 and the jack 12, and prevents poor contact caused by improper alignment. Example 3

[0047] Reference Figure 3, based on the embodiment 1, the embodiment of the present application further optimizes the operating mechanism 24. Specifically, the operating rod includes a handle 241 and a connecting rod assembly. One end of the handle 241 is arranged inside the housing 21 and is rotatably connected to the housing 21, and the other end extends to the outside of the housing 21. The handle 241 is connected to the plug 22 through the connecting rod assembly. The connecting rod assembly includes a first connecting rod 242, a second connecting rod 243 and a third connecting rod 244. The first connecting rod 242 and the second connecting rod 243 are hinged to the two plugs 22 one by one. The two connecting rods are hinged to each other through a rotating shaft. One end of the third connecting rod 244 is rotatably connected to the rotating shaft, and the other end is rotatably connected to the handle 241. Therefore, by turning the handle 241, the two plugs 22 can be controlled to move toward or away from each other, thereby realizing the synchronous extension and retraction of the two plugs 22, simplifying the user's operation steps, and only a simple rotation action is required to complete the installation and removal of the lightning protection module 2, thereby improving the user experience.

[0048] In addition to adopting the structural form of the turning handle 241, a push rod structural form can also be adopted. The push rod is inserted into the shell 21 and is slidably connected to the shell 21, that is, the push rod can move in its own length direction. One end of the push rod is connected to the plug 22 through a connecting rod assembly, and the other end extends to the outside of the shell 21. The operator controls the extension and retraction of the plug 22 by pulling the push rod.

[0049] The following will continue to further optimize the structure of the handle 241. Furthermore, the operating mechanism 24 also includes a paddle 245, which is arranged outside the housing 21 and fixedly connected to the handle 241. The housing 21 is provided with an arc portion 211 corresponding to the moving path of the paddle 245. The paddle 245 is arranged opposite to the arc portion 211 and moves along the length direction of the arc portion 211. The arrangement of the paddle 245 facilitates the user to operate the handle 241.

[0050] The present application also provides a locking mechanism 3 on the base 1, and the paddle 245 can cooperate with the locking mechanism 3 to lock the handle 241. Specifically, the locking mechanism 3 includes a spring latch 31, which is slidably disposed on the base 1, and the paddle 245 is provided with a clamping portion 246 that is engaged with the spring latch 31. After installing the lightning protection module 2, the user only needs to engage the spring latch 31 with the paddle 245 to lock the handle 241, thereby ensuring a stable connection between the plug 22 and the connector 13 and avoiding the risk of accidental loosening. When disassembling the lightning protection module 2, the handle 241 can be unlocked by moving the spring latch 31 to separate it from the paddle 245.

[0051] Furthermore, the spring latch 31 is fixedly connected to the connector 13, and the connector 13 is slidably arranged on the base 1 so as to be able to move synchronously with the connector 13. When the paddle 245 and the handle 241 are unlocked, the spring latch 31 moves while driving the connector 13 to move away from the plug 22, so that the plug 22 is separated from the connector 13, thereby reducing the resistance to the resetting of the handle 241 and the contraction of the plug 22, and facilitating disassembly.

[0052] In order to facilitate the operation of the spring tenon 31, the locking mechanism 3 further includes an operating part 32, which can be specifically configured as a pull rod, one end of which is fixedly connected to the spring tenon 31, and the other end extends to the outside of the base for easy operation by staff.

[0053] In order to make the two connectors 13 move synchronously, the present application further adds a transmission mechanism 4, referring to Figure 4 The transmission mechanism 4 includes a first rack 41, a second rack 42 and a gear 43. The first rack 41 and the second rack 42 are connected to the two connectors 13 one by one and are arranged in parallel. The gear 43 is arranged between the first rack 41 and the second rack 42 and is rotatably connected to the housing 21. The gear 43 is synchronously meshed with the first rack 41 and the second rack 42. Therefore, when the spring latch 31 drives one of the connectors 13 to move, the transmission mechanism 4 can drive the other connector 13 to move synchronously, thereby realizing the separation of the plug 22 and the connector 13.

[0054] The operating mechanism 24 also includes a reset spring 212 disposed inside the housing 21, one end of the reset spring 212 is fixedly connected to the housing 21, and the other end is fixedly connected to the operating handle. When the handle 241 is unlocked, it can automatically reset under the action of the reset spring 212, so that the plug 22 automatically retracts into the storage hole 23, which is convenient for subsequent disassembly operations. At the same time, when the lightning protection module 2 is installed, the elastic force provided by the reset spring 212 acts on the paddle 245, which can also enhance the tightness of the fit between the paddle 245 and the spring tenon 31, thereby improving the reliability and stability of the entire lightning protection module 2. Example 4

[0055] Based on the embodiment 3, the embodiment of the present application further optimizes the number of lightning protection modules 2 and the structure of the paddle 245. Specifically, there are multiple lightning protection modules 2, and the multiple lightning protection modules 2 are plugged and matched with the base 1.

[0056] Further, see Figure 5There are two clamping parts 246 on the paddle 245, and a clamping slot 2451 is formed between the two clamping parts 246. A connecting plate 247 is clamped in the clamping slot 2451. The connecting plate 247 can be connected to the paddles 245 on multiple lightning protection modules 2 at the same time, so that all the paddles 245 can move synchronously, and then the lightning protection module 2 can be unlocked and locked synchronously, which improves the efficiency of the synchronous operation of multiple modules.

[0057] In order to ensure the normal cooperation between the clamping portion 246 and the spring tenon 31 , an avoidance groove may be provided at a corresponding position of the connecting plate 247 .

[0058] In summary, the implementation principle of a conveniently replaceable power lightning arrester provided by the present application is: by designing the lightning protection module 2 to be pluggable, and introducing the operating mechanism 24 and the locking mechanism, the lightning protection module 2 can be quickly replaced and securely installed. Specifically, the user only needs to insert the lightning protection module 2 into the installation slot 11, and then use the operating rod (such as the turning handle 241) to push the plug 22 out and insert it into the jack 12, and then use the paddle 245 and the locking mechanism 3 to fix the turning handle 241, and then the lightning protection module 2 can be installed.

[0059] The locking mechanism 3 is unlocked, and under the action of the reset spring 212 , the plug 22 is automatically retracted into the receiving hole 23 , and the lightning protection module 2 can be separated from the base, thereby realizing the rapid disassembly of the lightning protection module 2 .

[0060] The above technical solution not only greatly reduces the difficulty of assembling and disassembling the lightning protection module 2, but also ensures its reliability during use, effectively solving the problems of inconvenient assembly and disassembly and poor stability in the prior art.

[0061] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
