Description

Technical Field

[0001] The invention relates to the technical field of outdoor high-voltage cabinets, in particular to an outdoor protective high-voltage cabinet. Background Art

[0002] High-voltage switchgear is an indispensable key equipment in the power system, and is widely used in power generation, transmission, distribution, power conversion and consumption. Its main function is to control the on-off of the circuit, provide protection measures, and ensure the stable operation of the power system. Depending on the working voltage, high-voltage switchgear can cover the range from 3.6kV to 550kV, suitable for power facilities of various sizes. This type of product mainly includes high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosers and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices, and comprehensive high-voltage switchgear.

[0003] In practical applications, high-voltage switchgear installed outdoors faces a series of special challenges, especially in terms of environmental adaptability and safety: ① Insufficient waterproof performance: Since most high-voltage switchgears are installed in outdoor environments, they are directly exposed to natural conditions, such as rain and snow. Traditional high-voltage cabinet designs often fail to fully consider the risk of rainwater penetration, especially when the seal is not tight, water vapor can easily invade the cabinet, causing internal electronic components to become damp or even short-circuit. In this case, it will not only affect the normal operation of the equipment, but may also cause serious safety accidents.

[0004] ② The contradiction between heat dissipation and dust prevention: In order to ensure that the internal electronic devices can work at a suitable temperature, an effective heat dissipation mechanism is essential. However, in an open heat dissipation design, when the fan or other cooling device is started, dust from the outside air will inevitably be sucked into the cabinet. After long-term accumulation, these tiny particles may cover the surface of components, reducing their working efficiency or even causing malfunctions. In addition, in a humid environment, dust and moisture are more likely to cause corrosion problems, further accelerating the aging of equipment.

[0005] ③ Stability under extreme weather conditions: In addition to the daily test of wind and rain, outdoor high-voltage cabinets also have to face the impact of extreme climates such as thunderstorms, hail, high or low temperatures. For example, when a lightning strike occurs, if there are no adequate lightning protection measures, the strong current shock may cause damage to the internal circuit; and in cold seasons, if there is a lack of proper insulation, some sensitive components may fail due to low temperatures. Therefore, how to improve the reliability and durability of equipment under various harsh conditions is an urgent problem to be solved.

[0006] ④ Mechanical vibration and collision protection: The choice of outdoor installation location is usually subject to geographical restrictions, and sometimes has to be close to roads or industrial areas, which increases the risk of vibration caused by vehicle traffic or construction activities. Strong mechanical vibration or accidental collision may pose a threat to precise electrical connections, thereby affecting the stability of the entire system. For this reason, special attention needs to be paid to the seismic and impact resistance of the structural design to ensure that normal working conditions can be maintained even under adverse conditions.

[0025] In some embodiments, see Figure 2 , Figure 6The buffer mechanism includes a protective frame 6, a second spring 61, a mounting plate 62, a limiting rod 66 and a fourth spring 67.

[0026] In some embodiments, see Figure 2 , Figure 3 , Figure 6 The waterproof and dustproof heat dissipation mechanism also includes a heat dissipation grille 4, a sealing connector 64 is fixedly installed between the top of the protective frame 6 and the inner wall of the cabinet 2, a connecting hole 68 is opened on the side near the bottom of the protective frame 6, a plurality of through holes 621 are opened inside the mounting plate 62, a flow hole 63 is opened on the top of the protective frame 6, a heat dissipation slot 41 is opened inside the cabinet 2, the heat dissipation fan 42 is fixedly installed at one end of the heat dissipation slot 41, and the heat dissipation grille 4 is fixedly installed at the other end of the heat dissipation slot 41.

By setting the connecting hole 68, the circulation hole 63 and the through hole 621, the air entering from the connecting pipe 5 from the outside can flow through the connecting hole 68, the through hole 621 and the circulation hole 63, and finally be transported to the outside through the heat dissipation groove 41 by the heat dissipation fan 42, so that the electronic components at the bottom of the mounting plate 62 can be cooled. By setting the heat dissipation fan 42 at the top, the heat dissipation can be better performed. By setting the sealing connector 64, the gap between the protective frame 6 and the cabinet 2 can be sealed to prevent air from flowing through the gap between the protective frame 6 and the cabinet 2.

[0027] In some embodiments, see Figure 2 , Figure 3The anti-static component includes a mounting seat 622, a third spring 625 and a clamping member 626. The mounting seat 622 is fixedly mounted on the top of the mounting plate 62. A slide groove 624 extending to the inside of the mounting plate 62 is provided inside the mounting seat 622. The clamping member 626 is movably connected to the inside of the slide groove 624 through the third spring 625.

[0028] In some embodiments, see Figure 2 , Figure 5 The adjusting connection mechanism includes a sliding member 12, a sliding rod 13, a connecting member 14 and an extending member 15. A mounting groove 11 is provided at the bottom of the base 1. The sliding rod 13 is fixedly installed on the inner wall of the mounting groove 11. The sliding rod 13 is slidably connected to the side wall of the sliding rod 13. The connecting member 14 is fixedly installed at the bottom of the sliding member 12. The connecting member 14 is located at the bottom of the base 1. The extending member 15 is fixedly installed on the side wall of the connecting member 14. The fixing bolt 16 is rotatably connected to the inside of the extending member 15. By setting the sliding rod 13, the sliding member 12 can slide in the mounting groove 11, so that the connecting member 14 and the extending member 15 can move at the bottom of the base 1. When the base 1 is installed, the position of the fixing bolt 16 inside the extending member 15 can be adjusted, making the installation more convenient and flexible.

[0029] In some embodiments, see Figure 1 A handle 31 is fixedly installed on one side of the cabinet door 3, and a baffle 21 is fixedly installed on the top of the cabinet body 2. The handle 31 can make the cabinet door 3 more convenient to open and close, and the baffle 21 can be used to block rainwater on the top of the cabinet body 2 on rainy days.

[0030] In specific applications, the base 1 and the cabinet 2 constitute the basic structure of the high-voltage cabinet. The base 1 not only provides mechanical support, but also enhances the installation flexibility through the adjustable connection mechanism set at its bottom. The cabinet 2 is provided with a movable cabinet door 3 to facilitate the inspection and maintenance of the internal electronic components. The baffle 21 on the top of the cabinet 2 is designed to protect the equipment in the cabinet from rain damage under severe weather conditions.

[0031] The adjustment connection mechanism is composed of a sliding member 12, a sliding rod 13, a connecting member 14 and an extending member 15, and is used in conjunction with a fixing bolt 16. The sliding member 12 can move along the sliding rod 13 in the installation groove 11 at the bottom of the base 1, thereby allowing the user to adjust the installation position of the base 1 according to actual conditions. This design enables the high-voltage cabinet to remain stable on different terrains and adapt to uneven ground, ensuring the convenience and reliability of installation.

[0032] The waterproof and dustproof heat dissipation mechanism is realized by the joint action of a series of components such as the connecting pipe 5, the guide rail 52, the first spring 521, etc. In particular, the connecting pipe 5 is equipped with a hydrophobic breathable membrane 56, which can prevent moisture from entering the cabinet 2 and ensure air circulation, which is crucial to prevent moisture from affecting electronic components in the outdoor environment. At the same time, the first filter 531 and the second filter 57 equipped in the system can effectively filter external dust and protect internal equipment from pollution. In addition, the heat dissipation fan 42 and the heat dissipation grille 4 located on the top of the cabinet 2 work together to achieve efficient heat dissipation and ensure the safe operation of the equipment.

[0033] The buffer mechanism is intended to reduce the vibration of the internal electronic components caused by external impact. The protection frame 6 is connected to the inner wall of the cabinet 2 through the second spring 61. When encountering a collision, these springs can absorb most of the energy and prevent sensitive components from being damaged. In addition, the design of the limit rod 66 and the fourth spring 67 further strengthens this protection mechanism, ensuring that sufficient protection can be provided for the electronic components even in extreme situations.

[0034] The anti-static assembly includes a mounting seat 622, a third spring 625 and a clamp 626, which work together to fix the electrostatic shielding plate 623. The electrostatic shielding plate 623 can effectively isolate the electronic components on the mounting plate 62 to avoid damage caused by static electricity accumulation. This feature is very important for improving the stability of the electronic system.

[0035] In actual application, the user first needs to adjust the position of the base 1 according to the site conditions, and then tighten the fixing bolts 16 to complete the installation. Next, during daily operation, the cooling fan 42 continues to operate to maintain the appropriate temperature in the cabinet; at the same time, the waterproof and dustproof device monitors environmental changes around the clock to ensure that the interior is clean and dry; finally, if an accidental impact occurs, the buffer mechanism will respond immediately to minimize the impact of the impact on the internal components.

[0036] Working principle: When in use, the positions of the connecting member 14 and the extension member 15 can be adjusted as needed. When the base 1 is installed, the position of the fixing bolt 16 inside the extension member 15 can be adjusted to make the installation more convenient and flexible. The air inside the cabinet 2 can be blown from the heat dissipation grille 4 to the outside of the cabinet 2 through the heat dissipation slot 41 through the heat dissipation fan 42, so that the inside of the cabinet 2 can be cooled. Through the connecting hole 68, the circulation hole 63, the through hole 621 and the connecting pipe 5, the heat dissipation fan 42 is operated so that the external air can enter the inside of the cabinet 2 through the connecting pipe 5. The first filter 531 and the second second filter 57 can block the dust passing through the inside of the connecting pipe 5, which has a better dustproof effect. The water vapor and water droplets entering the inside of the connecting pipe 5 can be blocked by the hydrophobic breathable membrane 56, so that the water liquid can be discharged from the circulation pipe. 55 flows to the bottom of the base 1 and is discharged to the outside of the cabinet 2, preventing water vapor and water droplets from entering the cabinet 2 through the connecting pipe 5, thereby achieving a good waterproof effect, so that the air entering from the connecting pipe 5 from the outside can flow through the connecting hole 68, the through hole 621 and the flow hole 63, and finally be transported to the outside through the heat dissipation slot 41 by the heat dissipation fan 42, so that the electronic components at the bottom of the mounting plate 62 can be cooled. By placing the heat dissipation fan 42 at the top, the heat dissipation can be better performed. The second spring 61 can be used for buffering when the cabinet 2 is impacted, preventing the protective frame 6 from being connected to the cabinet 2 and shaking violently, thereby providing buffering protection for the electronic components on the mounting plate 62 inside the protective frame 6. The third spring 625 can further increase the buffering effect, thereby achieving a better protection effect.
