Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, and in particular to a novel electrical fault alarm device for power systems. Background Technology

[0002] The new type of electrical fault alarm device for power systems is a frontline station for ensuring the safe and stable operation of the power grid. Its core function is to monitor the electrical parameters of key nodes in the power grid in real time. Through built-in intelligent algorithms, it can quickly identify and judge abnormal states in the system operation. Once it detects over-limit or dangerous signs, the device will immediately trigger multi-level alarms (audio-visual, SMS, work order system, etc.), accurately indicating the fault location and type, and providing maintenance personnel with the most timely fault information. It effectively shortens the fault detection and response time and is a key device to prevent the expansion of local faults and maintain the reliability of the new power system.

[0003] Existing electrical fault alarm devices for power systems still have some problems during use. For example, most electrical fault alarm devices are installed with bolts, which requires tools to remove them during maintenance or replacement. This is not only time-consuming, but also causes wear on the mounting holes due to repeated disassembly, thus reducing the stability of the device after installation. In addition, most devices cannot protect the diagnostic interface, making it susceptible to oxidation and corrosion due to external dust or moisture, which affects subsequent testing.

[0004] To address these issues, we provide a novel electrical fault alarm device for power systems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the electrical fault alarm device cannot be quickly disassembled, thus affecting subsequent maintenance, and most devices cannot protect the diagnostic interface, thus affecting subsequent testing work. Therefore, we propose a new type of electrical fault alarm device for power systems.

[0006] To achieve the above objectives, this application adopts the following technical solution: a novel electrical fault alarm device for power systems, comprising a housing, a fault alarm device body disposed on one side of the housing, connecting plates fixedly connected to both sides of the fault alarm device body, a horizontal plate fixedly connected to one side of the connecting plates, vertical rods fixedly connected to both sides of the inner cavity of the housing, sliding plates slidably connected to the top and bottom surfaces of the vertical rods, fixing plates fixedly connected to both sides of the top of the sliding plates, a limit plate fixedly connected to the bottom of the sliding plates, springs sleeved on the top and bottom surfaces of the vertical rods, a guide plate fixedly connected to one side of the fault alarm device body, and a sealing plate slidably connected inside the guide plate.

[0007] Preferably, a toggle plate is fixedly connected to one side of the sliding plate, and the toggle plate is used to drive the sliding plate to move.

[0008] Preferably, a sliding groove is provided on one side of the outer casing, and the actuating plate is slidably connected inside the sliding groove.

[0009] Preferably, mounting plates are fixedly connected to the top and bottom of the outer casing, and bolts are provided on one side of the mounting plates.

[0010] Preferably, the top and bottom of the horizontal plate are provided with limiting grooves, and the limiting plate is slidably connected inside the limiting grooves.

[0011] Preferably, the sealing plate has anti-slip texture on one side to increase the friction between the hand and the sealing plate.

[0012] Preferably, a movable groove is provided on the other side of the outer casing, and the fixed plate is slidably connected inside the movable groove.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model, through the setting of the spring, enables the sliding plate to drive the limiting plate to be locked into the horizontal limiting groove, thereby limiting the body of the fault alarm device. At the same time, the sliding plate will also drive the fixing plate to further limit the body of the fault alarm device, thereby ensuring the stability of the device during use. Combined with the setting of the toggle plate, it is possible to quickly disassemble and assemble the body of the fault alarm device by hand, thereby improving maintenance efficiency.

[0014] 2. By setting up a sealing plate and a guide plate, this utility model can seal the diagnostic interface, thereby preventing it from being corroded by external dust, moisture and other factors, and avoiding problems such as oxidation and short circuits of internal components due to long-term exposure, thus ensuring the safety of the diagnostic interface when it is not in use.

[0020] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0021] Example 1 Please see Figures 1-4 This utility model is a novel electrical fault alarm device for power systems, comprising a housing 1, a fault alarm device body 2 disposed on one side of the housing 1, connecting plates 3 fixedly connected to both sides of the fault alarm device body 2, a horizontal plate 4 fixedly connected to one side of the connecting plates 3, vertical rods 5 fixedly connected to both sides of the inner cavity of the housing 1, sliding plates 6 slidably connected to the top and bottom of the surface of the vertical rods 5, fixing plates 7 fixedly connected to both sides of the top of the sliding plates 6, a limit plate 8 fixedly connected to the bottom of the sliding plates 6, springs 9 sleeved on the top and bottom of the surface of the vertical rods 5, a guide plate 10 fixedly connected to one side of the fault alarm device body 2, and a sealing plate 11 slidably connected inside the guide plate 10.

[0022] Specifically: The fault alarm device body 2 can monitor key parameters such as current, voltage, and temperature in the power system in real time. When the detected parameter is abnormal and exceeds the preset threshold, it will quickly trigger the internal alarm mechanism. The vertical rod 5 can limit the sliding plate 6 to ensure that it will not deviate when moving. The top and bottom of the spring 9 are fixedly connected to the top of the inner cavity of the outer shell 1 and the top of the sliding plate 6, respectively. The guide plate 10 can limit the sealing plate 11 to ensure that it can slide up and down stably.

[0023] Example 2 Please see Figures 1-4Based on embodiment 1, a toggle plate 12 is fixedly connected to one side of the sliding plate 6, which is used to drive the sliding plate 6 to move. A sliding groove 13 is provided on one side of the outer shell 1, and the toggle plate 12 is slidably connected to the inside of the sliding groove 13. Mounting plates 14 are fixedly connected to the top and bottom of the outer shell 1, and bolts 15 are provided on one side of the mounting plates 14. Limiting grooves 16 are provided on the top and bottom of the horizontal plate 4, and limiting plates 8 are slidably connected to the inside of the limiting grooves 16. Anti-slip textures 17 are provided on one side of the sealing plate 11, which are used to increase the friction between the hand and the sealing plate 11. An movable groove 18 is provided on the other side of the outer shell 1, and a fixed plate 7 is slidably connected to the inside of the movable groove 18.

[0024] Specifically: the toggle plate 12 allows the user to easily move the sliding plate 6, thereby releasing the limit on the fault alarm device body 2, thus achieving the purpose of quickly disassembling and assembling the fault alarm device body 2; the mounting plate 14 and bolts 15 can fix the outer shell 1 inside the electrical equipment; the anti-slip texture 17 allows the user to easily move the sealing plate 11; and the limiting groove 16 can assist the limiting plate 8 in fixing the fault alarm device body 2.

[0025] Working principle: When it is necessary to remove the fault alarm device body 2, the user moves the toggle plate 12 with his / her finger, causing it to move within the sliding groove 13 of the outer casing 1. This causes the sliding plate 6 to move along the vertical rod 5. When the sliding plate 6 moves, it compresses the spring 9. The sliding plate 6 also causes the fixing plate 7 and the limiting plate 8 to move, causing the fixing plate 7 and the limiting plate 8 to separate from the connecting plate 3 and the limiting groove 16 respectively. This completely releases the limitation on the fault alarm device body 2. Then, the user can directly remove the fault alarm device body 2.

[0026] When installation is required, simply insert the horizontal plate 4 into the outer casing 1, then release the toggle plate 12. The spring 9 will then push the sliding plate 6 to move through its own elasticity, causing the limiting plate 8 to re-engage into the limiting groove 16. The fixing plate 7 will also simultaneously limit the connecting plate 3, thereby achieving the purpose of quickly disassembling and assembling the fault alarm device body 2.

[0027] When the fault alarm device body 2 needs to be tested, the user can directly push the sealing plate 11 up through the anti-slip texture 17 to expose the diagnostic interface, and then test it, thereby preventing external dust or moisture from affecting it.

[0028] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
