Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a novel integrated surge protector with self-disconnecting backup protection. Background Technology

[0002] In power transmission and distribution systems, surge protectors are used to protect substations, distribution cabinets, and critical electrical equipment such as transformers and switchgear. They prevent damage from overvoltage caused by lightning strikes or grid fluctuations. When a surge occurs, the protector quickly directs the overvoltage to ground, protecting the equipment. If the surge protector is at risk of failure due to repeated surges, its automatic disconnect function will activate to prevent further damage.

[0003] However, existing surge protectors are usually fixed in specific locations with screws and bolts to protect devices such as transformers. However, the screw and bolt fixing method is cumbersome and inconvenient, making it difficult for staff to replace the device when it is damaged. Therefore, a new type of surge protector with self-disconnecting backup protection is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 3 to 5This utility model provides an embodiment of a novel self-disconnecting backup protection integrated surge protector, comprising a mounting plate 1. The mounting plate 1 serves as the basic support structure of the device, providing a basic platform for installing and fixing other components, ensuring the stability of the device during operation. Fixing plates 2 are fixedly connected to both the front and rear ends of the right side of the mounting plate 1. Engaging plates 3 are fixedly connected to the right sides of both fixing plates 2. The fixing plates 3 support and fix the engaging plates 3, ensuring that the engaging plates 3 maintain a stable position during the installation and disassembly of the device, increasing the reliability of the device. The engaging plates 3, as a key component in contact with the housing 4, [further details needed]. The tight fit between the device and the pressure plate 11 ensures that the device can be quickly installed and securely fixed. A housing 4 is provided on the right side of the mounting plate 1. The housing 4 protects the internal components of the device and provides external protection to prevent dust and other external factors from affecting the internal components. Two fixing plates 5 are fixedly connected to the front and rear ends of the left side of the housing 4. A receiving shell 6 is fixedly connected to the left side of the fixing plate 5. A cavity 7 is opened inside the two receiving shells 6. A bearing component for bearing resistance is fixedly connected to the top inner wall of the cavity 7. A spring 9 is sleeved on the outside of the bearing component. A limit plate 10 is fixedly connected to the bottom of the bearing component.

[0033] The cavity 7 serves as a movement channel for the limiting plate 10, ensuring controlled sliding of the limiting plate 10 within the housing 6, thereby enabling the installation or disassembly of the device. The supporting components include a damper 8, one end of which is fixedly connected to the inner wall of the housing 6, and the other end of which is fixedly connected to the outside of the limiting plate 10. A pressure plate 11 is fixedly connected to the bottom of the limiting plate 10. The housing 6 provides space for the pressure plate 11 and the internal structure of the limiting plate 10, allowing these components to move flexibly within the housing and perform their functions. The outside of the limiting plate 10 is slidably connected to the inside of the cavity 7, and the damper 8... When the position plate 10 moves, it provides resistance to prevent the limit plate from moving too fast or too violently, thereby protecting other components of the device from impact and damage. One end of the spring-9 is fixedly connected to the outside of the limit plate 10, and the other end of the spring-9 is fixedly connected to the inner wall of the cavity 7. The spring-9 provides a restoring force for the limit plate 10 and the pressure plate 11, so that they can return to their original position after being squeezed, ensuring the stability and reusability of the device. The bearing component consists of the damper 8 and the spring-9, which provides the necessary damping and rebound force for the movement of the limit plate 10, ensuring that the pressure plate 11 can adapt to changes in external force during installation and disassembly.

[0034] The top of the pressure plate 11 contacts the bottom inner wall of the cavity 7, and the outside of the pressure plate 11 contacts the outside of the locking plate 3. The limiting plate 10 controls the position and movement path of the pressure plate 11 to ensure that the pressure plate can fit tightly with the locking plate 3, thereby realizing the quick installation and fixation of the device. The right side of the locking plate 3 contacts the left side of the housing 4. The pressure plate 11, through contact with the locking plate 3, plays the role of clamping and fixing the housing 4, ensuring that the device can remain stable after installation and can be easily separated during disassembly.

[0035] Reference Figure 1 and Figure 2 A cable divider 12 is fixedly connected to the right side of the mounting plate 1. The cable divider 12 is used to manage and classify the wires entering the device, ensuring that each wire has an independent channel and avoiding tangling and interference between wires. The top of the cable divider 12 has multiple wire inlet holes 13, which provide an independent channel for each wire entering the device, ensuring the neat arrangement of the wires and providing a basis for clamping and fixing. Support components for supporting the device are fixedly connected to the front and rear sides of the multiple wire inlet holes 13. Springs 15 are sleeved on the left and right sides of the outside of the support components. Clamping plates 16 are slidably connected to the left and right sides of the outside of the support components. The support components include two fixed rods 14, and the two clamping plates 16 are slidably connected to the left and right sides of the outside of the two fixed rods 14 respectively. The fixed rods 14 provide sliding tracks for the clamping plates 16, ensuring that the clamping plates can slide smoothly when the wires pass through and remain stable during clamping.

[0036] Spring 15 is sleeved on the outside of the fixing rod 14. One end of spring 15 is fixedly connected to the outside of the clamping plate 16, and the other end of spring 15 is fixedly connected to the inner wall of the inlet hole 13. Spring 15 provides elastic restoring force to the clamping plate 16, ensuring that the clamping plate can automatically clamp when the wire passes through the inlet hole 13, thereby preventing the wire from loosening or tangling. The support assembly consists of the fixing rod 14 and spring 15, which supports and guides the movement of the clamping plate 16, ensuring that the wire can be effectively clamped and fixed when entering the device. The clamping plate 16 is used to clamp and fix the wire passing through the inlet hole 13, ensuring that the wire is stable and stationary inside the device, and avoiding displacement or tangling during operation.

[0037] Working principle: First, when the device needs to be used, the housing 4 can be moved closer to the mounting plate 1. Then, the adjacent side of the two pressure plates 11 will be squeezed by the external pressure of the locking plate 3. Subsequently, the pressure plate 11 will drive the limiting plate 10 to move. Thus, the limiting plate 10 will move inside the cavity 7, and the cavity 7 can limit the limiting plate 10. Then, when the limiting plate 10 moves, it will press the damper 8. At the same time, the limiting plate 10 will compress the spring 9, which will allow the pressure plate 11 to enter the interior of the housing 6. Then, under the restoring force of the spring 9, the pressure plate 11 can be tightly fitted to the outside of the locking plate 3, thus realizing the quick installation of the housing 4. When the device needs to be disassembled and replaced, simply pull the housing 4 to disengage the pressure plate 11 from the locking plate 3.

[0038] After the device is installed, when it is necessary to connect the internal wiring, the wire can be passed through the inlet hole 13 opened at the top of the splitter plate 12. When the wire passes through the inside of the inlet hole 13, the wire will press against the clamping plate 16, causing the clamping plate 16 to slide outside the two fixing rods 14. Then, when the clamping plate 16 moves, it will compress the second spring 15. Then, under the return force of the second spring 15, the device can clamp and fix the wire, thereby preventing the wires connected to the inside of the device from getting tangled together.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
