Description

Technical Field

[0001] This utility model relates to the field of high-voltage ring network switchgear technology, specifically an outdoor high-voltage ring network switchgear with rainproof and lightning protection. Background Technology

[0002] High-voltage ring main units are designed to improve power supply reliability, allowing users to obtain power from two directions. They typically connect the power grid into a ring, a power supply method known simply as ring network power supply. In AC 10kV power distribution systems such as ports and high-rise buildings, where the load capacity is not large, the high-voltage circuits are usually controlled by load switches or vacuum contactors and equipped with high-voltage fuses for protection. These systems typically use ring network power supply, and the high-voltage switchgear used is generally referred to as ring main units.

[0003] A high-voltage ring main unit is an electrical device consisting of a set of high-voltage switchgear housed in a steel plate metal cabinet or assembled into a modular ring network power supply unit. Its core components utilize load switches and fuses, offering advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0004] Current outdoor high-voltage ring network switchgear offers insufficient lightning protection, with most relying on lightning rods. However, the protection range of lightning rods is limited, and their design and installation must strictly consider the height, shape, and layout of the building. Insufficient height or improper installation location of the lightning rod may prevent it from effectively attracting lightning. Regular maintenance of the lightning rod and its grounding system is necessary to prevent corrosion and loosening, which can reduce its conductivity. Due to the complexity of materials and manufacturing processes, the cost is high, and the performance of lightning rods may be affected in extreme environments. Excessive resistance in the grounding system or aging and corrosion of the lightning rod itself can lead to its failure. Furthermore, traditional high-voltage ring network switchgear is inconvenient to move and fix. Therefore, a rainproof and lightning-resistant outdoor high-voltage ring network switchgear is needed to address these issues. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-4 The outdoor high-voltage ring network switchgear shown includes a main body 1, a lightning protection component 2 fixedly connected inside the main body 1, and a movable fixed component 3 provided at the bottom of the main body 1.

[0027] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the lightning protection assembly 2 includes a support plate 201, with a mounting box 203 fixedly connected inside the support plate 201. A surge protector 204 and a signal surge protector 205 are fixedly connected inside the mounting box 203. A shielded cable 206 is fixedly connected to the side of the surge protector 204. The movable and fixed assembly 3 includes a base plate 301, with casters 302 at the bottom of the base plate 301. An adjusting support rod 303 is installed at the bottom of the base plate 301, and a foot 304 is fixedly connected to the output end of the adjusting support rod 303. By installing the surge protector 204 on the power input terminal and important data lines of the high-voltage ring network switchgear, lightning surges and voltage spikes can be effectively blocked. The shielded cable 206 can reduce electromagnetic interference. Installing the signal surge protector 205 at the signal line entrance of the high-voltage ring network switchgear can effectively protect the high-voltage ring network switchgear.

[0028] The support plate 201 has two support rods 207 fixedly connected to its bottom. Four mounting plates 202 are fixedly connected to the sides of the support rods 207. Antistatic strips 208 are wrapped around the sides of the support plate 201. The base plate 301, casters 302, adjusting support rods 303, and feet 304 are also provided. The distance between the base plate 301 and feet 304 can be controlled by adjusting the extension and retraction of the adjusting support rods 303, thereby controlling whether the casters 302 are suspended or on the ground. This allows for convenient movement and fixing of the high-voltage ring network switchgear, enabling rapid adjustment of the switchgear's position according to actual needs without being restricted by fixed installation.

[0029] In this embodiment, reference is made to Figure 1 and Figure 4As shown, the main body 1 includes a cabinet 101, a cooling fan 102 installed on the side of the cabinet 101, a waterproof plate 103 fixedly connected to the top of the cabinet 101, a top plate 104 fixedly connected to the top of the waterproof plate 103, a cabinet door 105 fixedly connected to the side of the cabinet 101, and a door lock 106 installed inside the cabinet door 105. The waterproof plate 103 has high tensile strength, tear strength and puncture strength, and can adapt to complex construction environments and long-term use. It has good resistance to chemicals such as acids, alkalis and salts, and is suitable for a variety of harsh environments. It has added anti-aging agents and ultraviolet absorbers, and can be used outdoors for a long time without aging. It has an extremely low water vapor permeability coefficient, which can effectively prevent the penetration of liquids and gases, thereby preventing moisture from entering the high-voltage ring network switchgear and causing damage.

[0030] In this solution, an outdoor high-voltage ring network switchgear with rain and lightning protection can be used by adjusting the extension and retraction of the support rod 303 to control the distance between the base plate 301 and the foot 304, thereby controlling whether the moving wheels 302 are suspended or on the ground. This allows for convenient movement and fixation of the high-voltage ring network switchgear. After the high-voltage ring network switchgear is fixed, surge protectors 204 are installed at the power input terminal and important data lines of the high-voltage ring network switchgear during thunderstorms and rainy weather. This can effectively block lightning surges and voltage spikes, while the shielded cable 206 can reduce electromagnetic interference, thus protecting the high-voltage ring network switchgear.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
