Description

Technical Field

[0001] The present invention belongs to the technical field of lightning arresters, and in particular relates to a plug-in lightning arrester and an assembling method thereof. Background Art

[0002] A lightning arrester is an important electrical protection device used to reduce the damage that lightning may cause to electronic equipment and electrical systems. It protects electrical equipment from damage by providing a low-impedance discharge channel to discharge excessive voltage to the ground. A lightning arrester is a device used to protect electronic equipment and electrical systems from lightning overvoltage and induced lightning. It is mainly divided into two categories: external lightning arresters and internal lightning arresters. External lightning arresters mainly include lightning rods, down conductors and grounding devices, which are used to prevent direct lightning strikes from damaging buildings and equipment; internal lightning arresters mainly include surge protectors, equipotential connectors and electromagnetic shielding.

[0003] Problems with existing technologies: Existing lightning arresters, especially surge protectors, will have their internal components damaged after a lightning strike or surge current. However, if they experience continuous surge current or lightning strikes, when the surge protector is damaged, the damaged components or disconnected metal conductive structures will generate arcs or sparks, causing the surge protector to burn out or even cause the entire circuit to malfunction. Summary of the Invention

[0004] The purpose of the present invention is to provide a plug-in lightning arrester and an assembly method thereof, which can realize that the internal structure of the surge protector can automatically disconnect and pop out after experiencing a surge current impact, thereby avoiding burning of the entire surge protector.

[0005] The technical solutions adopted by the present invention are as follows: A plug-in lightning arrester, comprising a base, and at least one surge plug module movably plugged into the base; The surge plug module is provided with a first plug and a second plug for plugging into the base at the end thereof, and the base is provided with a first connecting metal member and a second connecting metal member respectively adjacent to the first plug and the second plug for clamping and sleeved connection, and the first connecting metal member and the second connecting metal member are both provided with an elastic clamping plate on the side away from the surge plug module, and the elastic clamping plate is used to clamp the first plug and the second plug on both sides; A conductive member is provided between the first plug and the second plug and is embedded in the end of the surge plug module. An embedded plate is embedded in one side of the conductive member corresponding to the base. The conductive component and the embedded plate are moved away from each other after electricity is supplied between the first plug and the second plug.

[0006] A set of varistors is fixed inside the surge plug-in module. The first plug is electrically connected to the second plug through the first connection contact plate, metal connector, metal wire, second connection contact plate and conductive component arranged in sequence. The metal connector and the first connection contact plate are heating elements, and the metal connector and the first connection contact plate are soldered together with solder.

[0007] The conductive component is a heating element, and the embedded plate component is a shape memory metal element. A positioning plate is arranged in the middle of the embedded plate component for fixedly connecting multiple shape memory metal strips on both sides. The shape memory metal strips are deformed into a bent shape after heating.

[0008] The conductive component is an electromagnetic element, and the embedded plate component is a magnetic element.

[0009] A hinge rod is rotatably installed inside the surge plug-in module. One end of the hinge rod is provided with an indicator board. A return spring is fixedly connected to the top of the hinge rod adjacent to the indicator board. The other end of the hinge rod is used for interference coupling with the metal connector. When the metal connector is fixedly welded to the first connection contact plate, the return spring is in a tensioned state. When the metal connector is separated from the first connection contact plate, the return spring resets and contracts, dragging the indicator board to rotate and move upward.

[0010] A wiring terminal is fixedly connected to one side of one first connection metal part, and a wiring terminal is fixedly connected to one side of the second connection metal part on the other side. The number of insertions of the first connection metal part into the surge plug-in module is the same. The second connection metal part is used for inserting the second plugs on the other side of multiple surge plug-in modules.

[0011] An insulating end is fixed to the end of the first plug, and the insulating end is made of insulating material. When the embedded plate component is separated from the conductive component, the insulating end moves between the elastic clamping plates and is clamped and fixed by the elastic clamping plates.

[0012] The back surface of the elastic clamping plate on the adjacent side of the first connection metal part and the second connection metal part is set as a smooth surface. The opposite surface of the elastic clamping plate on the opposite side of the first connection metal part and the second connection metal part is set as a rough surface.

[0013] An assembly method of a plug-in lightning arrester includes the following steps: Based on at least one surge plug-in module that can be movably inserted into the base, the first plug and the second plug arranged on the surge plug-in module are movably inserted into the base. After the conductive component embedded on one side of the surge plug-in module is inserted into and plugged with the embedded panel component embedded on one side of the base, they are in positive alignment and fit together. After being energized from the first plug to the second plug, the driving separation between the conductive component and the embedded panel component is realized. At this time, the metal connecting piece and the first connection contact plate are also in a separated state. At this time, the surge plug-in module and the base are in a primary separation state. The insulating end is clamped and connected with the elastic splint, and the first plug and the second plug are in an open circuit state.

[0014] An assembly system of a plug-in lightning arrester includes lightning arresters composed of multiple groups of bases and surge plug-in modules, and the multiple lightning arresters are distributed. A corresponding temperature monitoring device is arranged at the installation position of the independently arranged lightning arrester. The temperature monitoring device is distributed corresponding to the lightning arrester. The temperature monitoring device is connected to a monitoring terminal through an electrical signal, and the monitoring terminal is signal-connected to a data processing terminal.

[0015] The technical effects achieved by the present invention are as follows: In the present invention, through the interaction between the conductive component and the embedded panel component, the surge plug-in module can be pushed to separate from the inside of the base by a certain distance. Since an insulating end is fixed at the end of the first plug and the insulating end is made of insulating material, the first connection metal piece is connected to the insulating end at this time, so as to physically disconnect the electrical connection between the surge plug-in module and the base, avoid being burned when a surge current impact occurs again, and also avoid the current continuously flowing into the surge plug-in module, causing the surge plug-in module to be burned, thus improving the overall safety of the base and the surge plug-in module.

[0016] In the present invention, the insulating end is clamped and fixed by the elastic splint. Through the insulating end, the disconnection between the first plug and the second plug at both ends of the surge plug-in module can be realized. Through the disconnection, the protection of the base and the surge plug-in module can be achieved, and the damage caused by secondary power-on can be avoided. Description of the Drawings

[0019] In order to make the purpose and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

For example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0021] The associated method embodiments can also be executed in an electronic device including a memory and a processor, a similar control device or the cloud. Taking the electronic device as an example, the electronic device may include one or more processors and a memory for storing data. Optionally, the above electronic device may further include a communication device for communication functions and a display device. Those of ordinary skill in the art can understand and know that the above structural description is only illustrative and does not limit the structure of the above electronic device. For example, the pre-positioning system may further include more or fewer components than the above structural description, or have a configuration different from the above structural description.

[0022] Such as Figure 1-3As shown, a pluggable lightning arrester includes a base 11 and at least one surge pluggable module 12 movably plugged into the base 11.

[0023] The surge plug module 12 has a first plug 129 and a second plug 130 at its ends for plugging into the base 11 . The base 11 has a first connecting metal piece 112 and a second connecting metal piece 113 respectively disposed adjacent to the first plug 129 and the second plug 130 for clamping and sleeve connection.

[0024] In addition to the plug-in connection between the first plug 129 and the second plug 130, the plug-in positioning is also achieved through the plug-in connection between the surge plug module 12 itself and the base 11, as well as the friction between them. When the first plug 129 is plugged into the first connecting metal member 112, and the second plug 130 is plugged into the second connecting metal member 113, the connection and transmission of electrical signals are achieved through the tight plug-in connection between the two.

[0025] Please refer to Figure 6 The first connecting metal member 112 and the second connecting metal member 113 are both located on the side away from the surge plug module 12 and are provided with an elastic clamping plate 1121 . The elastic clamping plate 1121 is used to clamp the first plug 129 and the second plug 130 on both sides.

[0026] Furthermore, a conductive member 131 is provided between the first plug 129 and the second plug 130 and is embedded in the end of the surge plug module 12 . The conductive member 131 is embedded in the side of the base 11 corresponding to the inner plate 114 .

[0027] The conductive member 131 and the embedded panel 114 are separated from each other after electricity is supplied between the first plug 129 and the second plug 130 .

[0028] According to the above structure, the principle is: After the base 11 transmits the surge current to the interior of the surge plug module 12, the conductive member 131 is energized, and the interaction between the conductive member 131 and the embedded plate 114 can push the surge plug module 12 away from the interior of the base 11 by a distance. Since the end of the first plug 129 is fixed with an insulating end 1291, and the insulating end 1291 is made of insulating material, the first connecting metal member 112 is now connected to the insulating end 1291, thereby physically disconnecting the electrical connection between the surge plug module 12 and the base 11, avoiding burning caused by another surge current impact, and preventing current from being continuously transmitted to the interior of the surge plug module 12, causing burning of the surge plug module 12, thereby improving the overall safety of the base 11 and the surge plug module 12.

[0029] Please refer to Figure 4 and Figure 5, a set of varistors 121 are fixed inside the surge plug-in module 12. The first plug 129 realizes electrical connection with the second plug 130 through the arranged first connection contact plate 128, metal connector 125, metal wire 126, second connection contact plate 127 and conductive member 131 in sequence.

[0030] Further, according to the existing conventional settings, a protection circuit board, a thermistor, etc. are also arranged inside the base 11 and the surge plug-in module 12.

[0031] The metal connector 125 and the first connection contact plate 128 are heating elements. The metal connector 125 and the first connection contact plate 128 are welded by solder. When the surge current is input through the first plug 129, the current passes between the first connection contact plate 128 and the metal connector 125, causing the first connection contact plate 128 and the metal connector 125 to heat up and melt the solder between the two, separating the two. During this process, after the current is transmitted to the varistor 121, the resistance decreases, and the current is grounded through the second plug 130.

[0032] Embodiment 1: Please refer to Figure 4-7 , the conductive member 131 is a heating element, and the embedded plate member 114 is a shape memory alloy element. A positioning plate 1141 is arranged in the middle of the embedded plate member 114 for fixedly connecting multiple shape memory alloy strips 1142 on both sides. The shape memory alloy strips 1142 are deformed into a curved shape after being heated.

[0033] According to the above structure, its principle is: When the conductive member 131 is powered on, it will generate heat by itself. The heat generation mechanism is the same as that of the metal connector 125 and the first connection contact plate 128. Subsequently, the conductive member 131 conducts the heat to the embedded plate member 114, so that the original curved shape of the shape memory alloy strips 1142 on both sides of the embedded plate member 114 changes, thereby generating a thrust force on the conductive member 131 and squeezing the surge plug-in module 12 to move.

[0034] Embodiment 2: The conductive member 131 is an electromagnetic element, and the embedded plate member 114 is a magnetic element.

[0035] According to the above structure, its working principle is: An electromagnetic coil is arranged inside the conductive member 131, and the thickness of the conductive member 131 can be increased to adapt to the installation of the coil.

[0036] In addition, when the embedded plate 114 is a magnetic element and the conductive member 131 is in an unpowered state, the iron core inside it and the embedded plate 114 are in a magnetic state, which can achieve magnetic positioning of the surge plug module 12. Although the magnetic attraction has little effect on the overall installation state of the surge plug module 12, when the indicator board 124 inside the surge plug module 12 indicates an error, if the conductive member 131 is not powered, it can be determined by judging whether the surge plug module 12 is ejected and whether the surge plug module 12 is in contact with the bottom. Whether the unplugged state between the bases 11 has magnetic drag can be used to determine whether the surge plug module 12 has been powered on and damaged. In addition, if the conductive member 131 is energized, the conductive member 131 and the embedded plate 114 repel each other, pushing the surge plug module 12 to move, and the embedded plate 114 is in a weak magnetic state, which will not magnetically reset the conductive member 131 and the surge plug module 12, and there is friction between the surge plug module 12 and the base 11, which can also achieve the effect of preventing the surge plug module 12 from being reset.

[0037] In combination with the above embodiments, and with reference to Figure 4-7 When the embedded plate 114 is separated from the conductive member 131, the insulating end 1291 moves between the elastic clamping plates 1121 and is clamped and fixed by the elastic clamping plates 1121. The insulating end 1291 can be used to disconnect the first plug 129 and the second plug 130 at both ends of the surge plug module 12. The disconnection protects the base 11 and the surge plug module 12 and prevents damage caused by secondary power-on.

[0038] Furthermore, the surface of the elastic clamping plate 1121 adjacent to the first connecting metal member 112 and the second connecting metal member 113 facing away from each other is set as a smooth surface, and the surface of the elastic clamping plate 1121 opposite to the first connecting metal member 112 and the second connecting metal member 113 facing away from each other is set as a rough surface.

[0039] For further details, refer to Figure 6 The smooth surface of the elastic clamping plate 1121 on the adjacent sides of the first connecting metal member 112 and the second connecting metal member 113, which faces away from the surface, can be a flat surface or an arc surface, to facilitate the connection between the surge plug module 12 and the base 11 and the sliding when the conductive member 131 interacts with the embedded plate 114. The principle is as follows: When the conductive member 131 interacts and separates from the embedded plate 114 , the first plugs 129 and the second plugs 130 on both sides are acted upon by the middle conductive member 131 , and the forces acting on the first plugs 129 and the second plugs 130 on both sides are directed inward, thereby reducing the friction between the outer sides of the first plugs 129 and the second plugs 130 , thereby facilitating the ejection of the surge plug module 12 .

[0040] The opposite surfaces of the elastic splint 1121 on the side of the first connecting metal part 112 facing away from the second connecting metal part 113 are set as rough surfaces to increase the friction between the first plug 129 and the second plug 130 and the insulating end 1291, which is used to realize the reset of the surge plug-in module 12 after it pops out from the base 11, and to improve the installation stability of the surge plug-in module 12 when installing the surge plug-in module 12.

[0041] Please refer to Figure 4 and Figure 5 Inside the surge plug-in module 12, a hinge rod 122 is rotatably installed. One end of the hinge rod 122 is provided with an indicator board 124. A return spring 123 is fixedly connected to the top of the hinge rod 122 adjacent to the indicator board 124. The other end of the hinge rod 122 is used for interference coupling with the metal connecting part 125. Further, when the metal connecting part 125 is fixedly welded to the first connecting contact plate 128, the return spring 123 is in a tensioned state. Furthermore, when the metal connecting part 125 is separated from the first connecting contact plate 128, the return spring 123 resets and contracts, dragging the indicator board 124 to rotate and move upward.

[0042] According to the above structure, the metal connecting part 125 and the hinge rod 122 are integrally provided. Therefore, during operation, unnecessary mechanical failures can be avoided, or the situation where a surge current passes through and the indicator board 124 at the end of the hinge rod 122 does not work can be avoided.

[0043] Refer to Figure 4-6 As shown, a wiring terminal 111 is fixedly connected to one side of a first connecting metal part 112, and a wiring terminal 111 is fixedly connected to one side of the second connecting metal part 113 on the other side. The number of insertions of the first connecting metal part 112 and the surge plug-in module 12 is the same. The second connecting metal part 113 is used to insert the second plugs 130 on the other side of multiple surge plug-in modules 12.

[0044] An assembly method of a plug-in lightning arrester includes the following steps: S1. Based on at least one surge plug-in module 12 that can be movably inserted into the base 11, the first plug 129 and the second plug 130 provided on the surge plug-in module 12 are movably inserted into the base 11. S2. After the conductive component 131 embedded on one side of the surge plug-in module 12 and the embedded plate member 114 embedded on one side of the base 11 are inserted, they are aligned and fitted together. S3. After being powered on through the first plug 129 to the second plug 130, the driving separation between the conductive member 131 and the embedded panel member 114 is realized. At this time, the metal connecting member 125 and the first connection contact plate 128 are also in a separated state. At this time, the surge plug-in module 12 and the base 11 are in a first-level separated state; S4. The insulating end 1291 is clamped and connected to the elastic splint 1121, and the first plug 129 and the second plug 130 are in an open circuit state.

[0045] Refer to the appendix Figure 8 , since the occurrence of surge current is relatively accidental and difficult to predict, therefore, for a large number of electrical boxes or control cabinets installed with lightning arresters 1, through the distributed setting of the lightning arresters 1 and the batch real-time monitoring of the lightning arresters 1, it is very necessary, which can further avoid the burning of the lightning arresters 1 or the burning caused by the lightning arresters 1.

[0046] An assembly system for a plug-in lightning arrester, including a lightning arrester 1 composed of multiple groups of bases 11 and surge plug-in modules 12, and multiple lightning arresters 1 are distributed; A corresponding temperature monitoring device 2 is provided at the installation position of the independently provided lightning arrester 1. The temperature monitoring device 2 is distributed corresponding to the lightning arrester 1. The temperature monitoring device 2 is connected to the monitoring terminal 3 through an electrical signal, and the monitoring terminal 3 is signal-connected to the data processing terminal 4.

[0047] Among them, the temperature monitoring device 2 is installed inside the electrical box or control cabinet for installing the lightning arrester 1. Further, through the temperature monitoring of the lightning arrester 1 and related components of the lightning arrester 1 by the temperature monitoring device 2, as well as the monitoring of the operating state, the monitoring of the lightning arrester 1 and related components is realized. In addition, in addition to the temperature monitoring device 2 can realize the temperature state monitoring of the lightning arrester 1, components such as the protection circuit board and thermistor located inside the lightning arrester 1 that can install components such as temperature sensors can also realize the real-time monitoring of the local temperature inside the lightning arrester 1, and through direct or indirect connection to the monitoring terminal 3, thereby realizing the real-time monitoring of the temperature. And by setting a corresponding alarm system on the monitoring terminal 3, when the temperature of the lightning arrester 1 reaches the initial threshold (the initial working of the input surge current of the lightning arrester 1), through the initial prompt of the monitoring terminal 3, and prompt to replace the surge plug-in module 12 on the lightning arrester 1. If the temperature of the lightning arrester 1 reaches the intermediate threshold (after the input surge current of the lightning arrester 1, the internal environment is at a high temperature, but there is no problem of excessive temperature), then an alarm prompt is given to prompt the maintenance personnel to check in time and find out the problem. If the temperature of the lightning arrester 1 reaches the peak threshold (the lightning arrester 1 or related electrical structures burn or approach the combustion threshold), then a warning prompt is issued, even blocking the power supply, or through the judgment of the decision-making by the data processing terminal 4, and through the data processing terminal 4 to automatically control the relevant distribution switches, and turn off the power supply related to the occurrence of fire or approaching the fire threshold to avoid further danger.

[0048] The data processing terminal 4 can also realize the data monitoring and management of multiple distributed monitoring terminals 3, can realize the centralized management and detection of more lightning arresters 1 set, reduce the detection efficiency. Further, through the data processing terminal 4, the monitoring and control of remote devices can be realized, and the monitoring of major dangerous situations and the avoidance of the occurrence of dangerous situations can be realized.

[0049] A distributed monitoring method for a plug-in lightning arrester includes the following steps: Ss1. Obtain the real-time temperature data of the corresponding detection position; Ss2. Set the corresponding temperature threshold, and compare the real-time temperature with the temperature threshold; Ss3. Judge the threshold type according to the temperature occurrence time and occurrence times; Ss4. The temperature threshold types include: initial threshold, intermediate threshold and peak threshold; Ss5. For the threshold types in step Ss4, feedback and generate different coping strategies; Ss6. Record the above occurrence conditions and conduct regular analysis to generate an automated program for computer processing, and realize the automatic judgment and processing of the above temperature threshold types in the later stage.

[0050] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented according to the conventional means in the art without special explanation and limitation.
