Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, specifically to a surge arrester monitoring device. Background Technology

[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltage hazards during lightning strikes and to limit the follow current time and amplitude. It can also protect against operational high voltage. When an overvoltage occurs, the resistance of the surge arrester drops sharply, and it quickly conducts, diverting the large current generated by the overvoltage to the ground, limiting the voltage amplitude, and protecting the insulation of electrical equipment. It is widely used in many fields such as power and communication and is a key component to ensure the safe operation of equipment.

[0003] Surge arresters are core components that protect electrical equipment from lightning overvoltages and switching overvoltages. Their performance directly affects the insulation safety of various critical equipment. If a surge arrester fails to conduct and discharge current properly when encountering overvoltage, the overvoltage will directly act on the protected equipment, causing serious accidents such as equipment burnout and system tripping. Monitoring devices can track the operating status of surge arresters in real time to ensure that they are always in an effective protective state.

[0004] Based on the performance characteristics of surge arresters, the performance degradation of surge arresters is usually manifested by abnormal heating, local overheating, partial discharge, etc. Severe partial discharge will generate pulse current. If this pulse current is very large, it will cause the zinc oxide varistor in the surge arrester to melt at the point of current accumulation. Damage to the zinc oxide varistor will cause great harm to the surge arrester and it must be taken out of operation to ensure the safe operation of the equipment.

[0005] However, in existing technologies, the entire group of surge arresters is usually disconnected. This not only requires timely manual detection, but also causes a power outage on all connected feeders, which is very inconvenient and affects production. Furthermore, in existing technologies, surge arresters are monitored by multiple sensors to analyze various indicators. When dealing with surge arresters with different operating environments and functions, multiple monitoring sensors need to be used. Integrating multiple sensors is not only costly, but also increases maintenance costs. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a surge arrester monitoring device.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: The device includes a main body of a monitoring instrument, an internal relay connection mechanism, three module mounting bases at the top of the main body, a detection module at the top of each module mounting base, three surge arresters evenly distributed at the front end of the main body, and a mounting plate with a relay base fixedly connected to its top. Three disconnection components are evenly fixedly connected to the front end of each relay base, with connecting wires fixedly connected to the front end of each disconnection component. An electric push rod, whose rear end is fixedly connected to the front end of the relay base, is fixedly connected to the upper rear side of each disconnection component.

[0008] The beneficial effects of this utility model are as follows: A single-group disconnection function is achieved through a relay connection mechanism. This mechanism includes three independent disconnection components, each corresponding to one surge arrester. When a single surge arrester fails, only the faulty device is disconnected, while the remaining surge arresters operate normally, ensuring power supply continuity and reducing the impact on production. The rapid and independent disconnection of the faulty device prevents the fault from spreading to other surge arresters, reducing the probability of damage to the entire group of equipment and lowering the total maintenance cost. Furthermore, the modular mounting base allows for flexible adaptation of the monitoring module, enabling individual selection of monitoring modules according to actual needs, reducing hardware costs. Damaged monitoring modules can be quickly replaced, simplifying the maintenance process.

[0009] Furthermore, the main body of the monitor includes a monitor housing, a partition plate is fixedly connected to the middle of the inner wall of the monitor housing, the front top of the partition plate is fixedly connected to the bottom of the mounting plate, the rear top of the partition plate is fixedly connected to a central control body, the front end of the central control body is fixedly connected to the rear end of the relay seat, and three mounting arms are evenly fixedly connected to the front end of the monitor housing, with the front ends fixedly connected to the bottom end of the surge arrester. The rear ends of the mounting arms extend into the interior of the monitor housing and are fixedly connected to the front end of the nearest connection line. As a whole device, it plays a role in overall protection and control, and provides a path for circuit connection.

[0010] Furthermore, the disconnection assembly includes a connection socket fixedly connected to the lower front side of the repeater base. The connection socket is equipped with a connection plug inside. The front end of the connection plug is fixedly connected to the rear end of the connection line. By inserting the connection plug into the connection socket, the circuit connection between the connection line and the repeater base is realized, thereby completing the connection between the surge arrester and the internal circuit of the device.

[0011] Furthermore, an elastic clamping hoop is fixedly connected to the rear side of the outer surface of the connecting wire by clamping. The upper rear end of the elastic clamping hoop is fixed to the output end of the nearest electric push rod by clamping. A movable guide rail with its bottom end fixed to the top of the partition plate is slidably connected to the bottom side of the outer surface of the elastic clamping hoop. Fixing screws are threaded to the left and right sides of the elastic clamping hoop. By clamping the connecting wire and the electric push rod together by the elastic clamping hoop, it is possible to disassemble and replace the connecting wire when it is damaged, and ensure that the connecting plug remains stable during movement, avoiding the impact of displacement on the circuit connection effect.

[0012] Furthermore, the module mounting base includes a connecting base fixedly connected to the top of the monitor housing. A module connector is provided at the center of the top of the connecting base. An installation frame is fixedly connected to the outer side of the top of the connecting base. A sealing strip is fixedly connected to the center of the inner wall of the installation frame. Two mirror-symmetrical mounting buckles are fixedly connected to the front and rear sides of the top of the connecting base to fix the detection module together, ensuring the stability and reliability of the detection module installation.

[0013] Furthermore, the mounting buckle includes a buckle body fixedly connected to the top of the module connector. A toothed claw is provided on one side of the buckle body, and a storage groove is provided on the side of the buckle body away from the toothed claw. The toothed claw can engage with the corresponding structure on the detection module to achieve initial fixation of the detection module. The storage groove provides space for the fitting spring sheet.

[0014] Furthermore, a fitting spring is rotatably connected to the top of the inner side of the storage slot, and a movable column is fixedly connected to the end of the fitting spring away from the storage slot. A movable groove is opened on the inner wall of the storage slot for the movable column to slide. The fitting spring rotates under the pressure of the detection module, and at the same time, the fitting spring undergoes elastic deformation. Its elastic force acts on the detection module, making the teeth of the buckle body engage more tightly with the detection module. Attached Figure Description

[0022] Example 1 Figure 1 This is a structural diagram of a surge arrester monitoring device provided for an embodiment of this utility model. Figure 1 The device includes a monitoring instrument body 4, a relay connection mechanism 5 inside the monitoring instrument body 4, three module mounting bases 3 at the top of the monitoring instrument body 4, a detection module 2 at the top of the module mounting base 3, and three surge arresters 1 evenly arranged at the front end of the monitoring instrument body 4.

[0023] With the main body 4 of the monitor as the core supporting component, the internal relay connection mechanism 5 is responsible for the connection and disconnection control between the surge arrester 1 and the internal circuit of the device. The three module mounting bases 3 at the top of the main body 4 of the monitor are used to provide the installation foundation for the detection module 2, ensuring that the detection module 2 is stably assembled to realize the monitoring function of the surge arrester 1. The detection module 2 completes the real-time monitoring of the working status of the surge arrester 1 by collecting the operating data of the surge arrester 1. All components work together to form a complete surge arrester 1 monitoring system, realizing the basic functions from data acquisition to equipment support.

[0024] The detection module 2 uses a common standard interface to connect to the module mounting base 3 and the main body 4 of the monitoring instrument to analyze and monitor various data of the surge arrester 1. This is existing technology and will not be explained here.

[0025] Figure 2 This is a cross-sectional view of the internal structure of the monitoring instrument of this utility model. Figure 2 As shown, the main body of the monitoring instrument 4 includes a monitoring instrument housing 44. A partition plate 42 is fixedly connected to the middle of the inner wall of the monitoring instrument housing 44. A central control body 43 is fixedly connected to the rear side of the top of the partition plate 42. Three mounting arms 41, which are fixedly connected to the bottom of the surge arrester 1, are evenly fixedly connected to the front end of the monitoring instrument housing 44. The rear end of the mounting arms 41 extends into the interior of the monitoring instrument housing 44.

[0026] The outer casing 44 of the monitor mainly serves as overall protection and control, preventing internal components from being affected by the external environment. It can be opened by flipping the cover. The partition plate 42 in the middle of the inner wall divides the interior of the monitor body 4 into different functional areas, protecting the circuits that conduct current to ground below. The front top of the partition plate 42 provides fixed support for the relay connection mechanism 5. The central control body 43 serves as the control core of the device. The three mounting arms 41 are fixedly connected to the surge arrester 1, ensuring that the surge arrester 1 is stably mounted on the front end of the monitor body 4 and connected to the circuit of the relay connection mechanism 5, laying the foundation for subsequent data transmission and disconnection control.

[0027] Figure 3 This is a structural diagram of the relay connection mechanism of this utility model. Figure 3 As shown, the relay connection mechanism 5 includes a mounting plate 55, a relay base 54 is fixedly connected to the top of the mounting plate 55, three disconnection components 52 are evenly fixedly connected to the front end of the relay base 54, a connecting line 51 is fixedly connected to the front end of the disconnection component 52, and an electric push rod 53 whose rear end is fixedly connected to the front end of the relay base 54 is fixedly connected to the upper side of the rear end of the disconnection component 52.

[0028] The relay connection mechanism 5 uses the mounting plate 55 as the installation base. The mounting plate 55 is fixed to the internal structure of the main body 4 of the monitoring instrument. The relay base 54 serves as the core support component, providing an installation carrier for the three disconnection components 52 that are uniformly fixed at the front end and regulating the current. The connecting line 51 is used to realize the circuit connection with the surge arrester 1, transmitting the current and data of the surge arrester 1 to the subsequent processing components. After receiving the control signal, the electric push rod 53 can drive the disconnection component 52 to act, realizing the disconnection or connection of the surge arrester 1 and the device circuit. The three disconnection components 52 correspond to the three surge arresters 1 respectively, and can independently complete the connection and disconnection control of a single surge arrester, ensuring the flexibility and reliability of the device operation.

[0029] The electric push rod 53 can extend and retract by the current controlled by the central control body 43. Under the control of the central control body 43, the disconnection of the control circuit is a prior art and will not be explained here.

[0030] Figure 4 This is an exploded view of the disconnection component of this utility model. (See attached image.) Figure 4 As shown, the disconnection assembly 52 includes a connection socket 521 fixedly connected to the lower front side of the repeater 54. A connection plug 522 is provided inside the connection socket 521. The front end of the connection plug 522 is fixedly connected to the rear end of the connection line 51. An elastic clamping hoop 523 is fixedly connected to the rear side of the outer surface of the connection line 51 by clamping. The upper rear end of the elastic clamping hoop 523 is fixedly connected to the front output end of the nearest electric push rod 53 by clamping. A movable guide rail 524 with its bottom end fixedly connected to the top of the partition plate 42 is slidably connected to the bottom side of the outer surface of the elastic clamping hoop 523. Fixing screws 525 are threadedly connected to the left and right sides of the elastic clamping hoop 523.

[0031] The connector socket 521 serves as the fixed end for circuit connection, providing an insertion interface for the connector plug 522. By inserting the connector plug 522 into the connector socket 521, the circuit connection between the connector wire 51 and the repeater 54 is achieved, thereby completing the connection between the surge arrester 1 and the internal circuit of the device. The elastic clamp 523, driven by the electric push rod 53, can move the connector plug 522 along the moving guide rail 524 to separate or connect the connector plug 522 and the connector socket 521, thereby completing the disconnection or connection action. On the other hand, the sliding connection between the elastic clamp 523 and the moving guide rail 524 ensures that the connector plug 522 remains stable during movement, avoiding the impact of deviation on the circuit connection effect, and ensuring the accuracy and reliability of the disconnection component 52's action. Through the joint clamping of the connector wire 51 and the electric push rod 53 by the elastic clamp 523, the connector wire 51 can be disassembled and replaced when damaged.

[0032] The elastic clamp 523 is made of an elastic metal sheet and can expand without the restriction of the fixing screw 525, so that the connector 522 can pass through the expanded elastic clamp 523, thereby allowing the connector 51 and connector 522 to be replaced.

[0033] Example 2 Based on Embodiment 1, the present invention can be further improved as follows: Figure 5 This is a structural diagram of the module mounting base of this utility model. Figure 5 As shown, the module mounting base 3 includes a connecting base 34 fixedly connected to the top of the monitor housing 44. A module connector 35 is provided in the middle of the top of the connecting base 34. An installation frame 31 is fixedly connected to the outer side of the top of the connecting base 34. A sealing strip 32 is fixedly connected to the middle of the inner wall of the installation frame 31. Two mirror-symmetrical mounting buckles 33 are fixedly connected to the front and rear sides of the top of the connecting base 34.

[0034] The connecting base 34 provides a stable installation foundation for the entire module mounting base 3. The module connector 35 is used to realize the signal connection between the detection module 2 and the internal circuit of the monitoring instrument body 4. The mounting frame 31 plays a limiting role for the detection module 2, preventing the detection module 2 from shifting laterally after installation. The sealing strip 32 can enhance the sealing between the detection module 2 and the mounting frame 31, preventing external dust, moisture and other substances from entering the module mounting base 3 and affecting the performance of the components. The detection module 2 is fixed on the module mounting base 3 by the mounting buckle 33, preventing the detection module 2 from falling off due to vibration and other factors during operation, and ensuring the stability and reliability of the installation of the detection module 2.

[0035] Figure 6 This is a diagram of the mounting clip structure of this utility model. Figure 6 As shown, the mounting buckle 33 includes a buckle body 331 fixedly connected to the top of the module connector 35. A toothed claw is provided on one side of the buckle body 331. A storage groove 333 is provided on the side of the buckle body 331 away from the toothed claw. A fitting spring piece 332 is rotatably connected to the top of the inner side of the storage groove 333. A movable column 334 is fixedly connected to the end of the fitting spring piece 332 away from the storage groove 333. A movable slide groove 335 is provided on the inner wall of the storage groove 333 for the movable column 334 to slide.

[0036] The buckle body 331 is the foundation of the entire buckle structure. The teeth on one side of the buckle can engage with the corresponding structure on the detection module 2 to achieve initial fixation of the detection module 2. The storage groove 333 provides space for the fitting spring 332. When the detection module 2 is installed, the fitting spring 332 rotates under the pressure of the detection module 2. The moving column 334 slides along the moving slide 335. At the same time, the fitting spring 332 undergoes elastic deformation. Its elastic force acts on the detection module 2, making the teeth of the buckle body 331 engage more tightly with the detection module 2, further enhancing the fixation effect on the detection module 2.
