Description

Technical Field

[0001] This utility model belongs to the technical field of overvoltage protectors, specifically relating to a three-phase six-column overvoltage protector with a protective structure. Background Technology

[0002] Three-phase six-limb overvoltage protectors are key devices in power systems used to protect electrical equipment from overvoltage damage. With the development and increasing complexity of power systems, higher requirements are placed on the safety performance and protection capabilities of overvoltage protectors.

[0003] Traditional overvoltage protectors typically consist of a simple structure, mainly comprising core protection components and a basic protective enclosure. However, these traditional designs have limitations in terms of safety protection, structural stability, and environmental adaptability, and cannot meet the demands of modern power systems for high-performance protection devices.

[0004] Traditional overvoltage protectors have limited safety protection measures, especially during operation and maintenance, where operators may directly contact live parts, posing a risk of electric shock. The casing design of traditional overvoltage protectors may not effectively prevent the intrusion of environmental factors such as rain and dust, leading to damage to internal electronic components and affecting the normal operating life of the equipment.

[0005] In view of this, we propose a three-phase six-column overvoltage protector with a protective structure. Utility Model Content

[0006] The present invention aims to solve the technical problem that the overvoltage protectors in the prior art are usually composed of simple structures such as core protection components and basic protective shells, which are not good in terms of safety protection.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A three-phase six-column overvoltage protector with a protective structure includes an anti-contact sleeve, a protective sleeve, a socket plate, and a take-up cover;

[0009] The anti-touch sleeve is fixed on the housing of the three-phase six-column overvoltage protector and is fitted on the outer side of the grounding terminal. When the grounding terminal is connected to the grounding wire, the anti-touch sleeve protects the connection point from being touched.

[0010] The protective sleeve is threaded onto the outer side of the terminal block and threadedly engages with the internal threaded ring on the top of the housing to protect the terminal block.

[0011] The socket plate is fitted onto the outer side of the protective sleeve and is threadedly connected to the protective sleeve via a double threaded sleeve.

[0012] The take-up cover is fitted over the outer side of the connecting wire. The take-up cover engages with the annular ring on the top of the socket plate to hold the connecting wire in the cavity formed by the take-up cover and the annular ring. A protective cover is fixed on the back of the take-up cover and fitted over the outer side of the terminal block on the connecting wire to protect the connection point between the terminal block and the connecting wire.

[0013] The protective sleeve, protective cover, socket plate, and cable retractor together constitute the protective structure for a three-phase six-terminal overvoltage protector. The protective sleeve provides an isolation layer to prevent operators from directly contacting live parts. The protective cover's design, covering the outer side of the terminals, prevents the terminals from being directly affected by the external environment. The socket plate provides additional stability and support for the protective sleeve, ensuring the overall structural robustness. The cable retractor, engaging with the annular ring on the top of the socket plate, houses the terminals and connecting wires within a protective chamber. A protective cover fixed to the back further protects the connection points of the terminals and connecting wires.

[0014] Preferably, the double threaded sleeve includes an external threaded sleeve and an internal threaded sleeve fixed inside the external threaded sleeve.

[0015] Preferably, the internal thread of the double-threaded sleeve is threaded onto the outer side of the external thread at the top of the protective sleeve, and the external thread of the double-threaded sleeve is threaded onto the outer side of the annular thread at the top of the sleeve plate.

[0016] The design of the double-threaded sleeve provides a dual locking mechanism, with the internal threaded sleeve and the external threaded sleeve connecting to the protective sleeve and the socket plate respectively, increasing the stability of the overall structure.

[0017] Preferably, handles are provided on both sides of the socket plate. The handles provide easy gripping points, allowing operators to easily lift the three-phase six-pole overvoltage protector. The combination of handles and socket plate design can prevent equipment damage caused by personnel lifting the connection wires.

[0018] Preferably, the bottom of the socket plate has a circular concave groove that fits over the outer side of the protective sleeve. This improves the fit between the socket plate and the protective sleeve.

[0019] Preferably, the inner surface of the annular ring is provided with several arc-shaped blocks arranged at equal intervals, and a groove is formed between two adjacent arc-shaped blocks and the annular ring. The bottom of the take-up cover is provided with a locking block that engages with the groove. When the three-phase six-column overvoltage protector is not in use, the connecting wires can be stored in the cavity formed by the take-up cover and the annular ring, keeping the connecting wires neat and fixed, thereby improving the reliability of the entire system. When in use, the take-up cover can be opened for easy wiring with the equipment.

[0020] Compared with existing technologies, the technical effects and advantages of this utility model are as follows: This three-phase six-column overvoltage protector with a protective structure achieves safe protection of live parts and structural stability through a combination of physical isolation and mechanical locking. The anti-contact sleeve and protective sleeve provide an isolation layer for operators, avoiding direct contact with live parts, while the double-threaded sleeve design, through the cooperation of internal and external threads, achieves a firm connection between the protective sleeve and the socket plate, forming a double locking mechanism to ensure the stability of the overall structure.

[0021] The protective sleeve, protective cover, socket plate, and cable retractor together form the protective structure for a three-phase six-limb overvoltage protector. The modular design of the protective structure simplifies installation and disassembly. The handle and circular concave groove design of the socket plate allow operators to easily lift and install the protector while maintaining compatibility between the equipment and the protective structure. The cable retractor and ring design allow the connecting wires to be stored in a protective chamber when not in use, preventing damage from external environmental factors, while the cable retractor can be easily opened for wiring when in use.

[0022] The protective structure design reduces the risk of electric shock to operators, improves equipment reliability, and simplifies daily maintenance and repair procedures. Its effectiveness protects equipment from environmental factors such as rain and dust, extending its service life. Furthermore, the easy-to-disassemble and assemble design reduces maintenance time and costs, improving the overall operational efficiency of the power system. Attached Figure Description

[0030] 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.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a three-phase six-column overvoltage protector with a protective structure, including an anti-contact sleeve 1, a protective sleeve 4, a socket plate 7, and a take-up cover 8.

[0033] The anti-touch sleeve 1 is fixed on the housing 2 of the three-phase six-column overvoltage protector and is sleeved on the outer side of the grounding terminal 3. When the grounding terminal 3 is connected to the grounding wire, the anti-touch sleeve 1 provides anti-touch protection for the connection.

[0034] The protective sleeve 4 is threaded onto the outer side of the terminal 5 and threadedly mats with the internal thread ring 6 on the top of the housing 2, and is used to protect the terminal 5.

[0035] The socket plate 7 is fitted onto the outer side of the protective sleeve 4 and is threadedly connected to the protective sleeve 4 via a double-threaded sleeve 12; the double-threaded sleeve 12 includes an external threaded sleeve 1201 and an internal threaded sleeve 1202 fixed inside the external threaded sleeve 1201. The internal threaded sleeve 1202 on the double-threaded sleeve 12 is threadedly engaged with the outer side of the external threaded portion 13 at the top of the protective sleeve 4, and the external threaded sleeve 1201 on the double-threaded sleeve 12 is threadedly engaged with the outer side of the annular threaded opening 14 at the top of the socket plate 7.

[0036] The design of the double-threaded sleeve 12 provides a dual locking mechanism. The internal threaded sleeve 1202 and the external threaded sleeve 1201 are connected to the protective sleeve 4 and the socket plate 7 respectively, increasing the stability of the overall structure. The design of the double-threaded sleeve 12 simplifies the installation process, allowing operators to quickly and accurately assemble the components.

[0037] The socket plate 7 has handles 15 on both sides. A circular concave groove 16 is formed at the bottom of the socket plate 7, fitting over the outer side of the protective sleeve 4. The handles 15 provide a convenient gripping area, allowing operators to easily lift the three-phase six-column overvoltage protector. The combined design of the handles 15 and the socket plate 7 prevents equipment damage caused by personnel lifting the connecting cable 9. The circular concave groove 16 better adapts to the shape of the protective sleeve 4, improving the fit between the socket plate 7 and the protective sleeve 4 and increasing overall stability.

[0038] The take-up cover 8 is fitted onto the outer side of the connecting wire 9. The take-up cover 8 engages with the annular ring 10 on the top of the socket plate 7 to hold the connecting wire 9 within the cavity formed by the take-up cover 8 and the annular ring 10. A protective cover 11 is fixedly provided on the back of the take-up cover 8, which is fitted onto the outer side of the terminal 20 on the connecting wire 9 to protect the connection point between the terminal 20 and the connecting wire.

[0039] The inner side of the ring 10 is provided with a number of arc-shaped blocks 17 arranged at equal intervals. A slot 18 is formed between two adjacent arc-shaped blocks 17 and the ring 10. The bottom of the take-up cover 8 is provided with a locking block 19 that can be inserted into the slot 18.

[0040] The design of the arc-shaped block 17 and the slot 18 allows the take-up cover 8 to be firmly fixed on the socket plate 7, preventing it from falling off due to external factors (such as vibration). The design of the block 19 snapping into the slot 18 makes the installation and removal of the take-up cover 8 more convenient. Through this structural design, it can be ensured that when the three-phase six-column overvoltage protector is not in use, the connecting wire 9 can be stored in the cavity formed by the take-up cover 8 and the ring 10, keeping the connecting wire neat and fixed, thereby improving the reliability of the entire system. When in use, the take-up cover 8 can be opened for easy wiring with the equipment.

[0041] The protective sleeve 1, protective sleeve 4, socket plate 7, and cable retractor 8 together constitute a protective structure for a three-phase six-post overvoltage protector. The protective sleeve 1 is fixed to the overvoltage protector housing 2 and covers the outer side of the grounding terminal 3. When the grounding wire is connected to the grounding terminal 3, the protective sleeve 1 provides an isolation layer to prevent operators from directly contacting live parts. The protective sleeve 4 is threaded to the internal threaded ring 6 on the top of the housing 2, allowing for easy installation and fixation without disassembly. Its design, covering the outer side of the terminal 5, prevents the terminal 5 from being directly affected by the external environment. The socket plate 7 is threaded to the protective sleeve 4 via a double-threaded sleeve 12, providing additional stability and support for the protective sleeve 4 and ensuring the robustness of the entire structure. The cable retractor 8 cooperates with the annular ring 10 on the top of the socket plate 7, housing the terminal 20 and connecting wire within a protective chamber. The protective cover 11, fixed to the back, further protects the connection point between the terminal 20 and the connecting wire.

[0042] This design reduces the risk of operators directly contacting live parts, preventing electric shock accidents. The protective structure effectively protects the equipment from environmental factors such as rain and dust, improving operational reliability. The structure is also designed for easy disassembly and assembly, making routine maintenance and repairs more convenient.

[0043] The protective sleeve 1 and protective sleeve 4 are designed to prevent operators from directly contacting live parts, especially when the grounding wire is connected to the grounding terminal 3. The protective sleeve 1 provides an isolation layer, which can effectively reduce the risk of electric shock.

[0044] The design of the double-threaded sleeve 12, with the inner threaded sleeve 1202 and the outer threaded sleeve 1201 connected to the protective sleeve 4 and the socket plate 7 respectively, forms a double locking mechanism, enhancing the stability of the entire protective structure. The double-threaded sleeve 12 design simplifies the installation process, allowing operators to quickly and accurately assemble components. Furthermore, the easy-to-disassemble and assemble protective structure design makes daily maintenance and repair of the equipment more convenient. The protective sleeve 4, cable retractor 8, and other structures can prevent damage to the equipment from environmental factors such as rain and dust, thus improving the reliability of equipment operation.

[0045] By utilizing physical isolation, such as the protective sleeve 1 and protective sleeve 4, direct contact between the human body and live parts is prevented, thus reducing the occurrence of electric shock accidents. Through mechanical structural design, utilizing the tightness of threaded connections and a double locking mechanism, the protective structure remains stable and will not easily detach even under vibration or other external influences. The modular design allows for quick assembly and disassembly of each part, reducing maintenance time and complexity, and lowering maintenance costs.

[0046] By designing the external structure of the equipment to be enclosed or semi-enclosed, harmful factors from the external environment (such as water, dust, and corrosive gases) are prevented from entering the equipment, thus protecting the internal electronic components from damage and ensuring the long-term stable operation of the equipment. The combination of these design principles not only improves the safety of the overvoltage protector but also enhances its environmental adaptability and maintainability, which is crucial for ensuring the stable operation of the power system.

[0047] 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.
