Description

Technical Field

[0001] This utility model relates to the technical field of anti-islanding devices, specifically a low-voltage anti-islanding device suitable for installation in various environments. Background Technology

[0002] Anti-islanding devices, also known as anti-islanding protection devices, are mainly used to prevent the islanding effect in the power grid. Islanding is an electrical phenomenon that occurs when a part of the power grid is disconnected from the main power grid, and this part of the grid is entirely powered by the photovoltaic system. Islanding can endanger the safety of the public and power company maintenance personnel, as well as the quality of power supply. Therefore, anti-islanding devices must be installed in photovoltaic power plants.

[0003] Anti-islanding devices are typically installed in the power grid. However, due to the limitations of the installation environment and the lack of a suitable installation structure, different auxiliary structures are needed to facilitate the installation and use of anti-islanding devices in different environments. This results in low installation efficiency and prevents the devices from being quickly installed and used in various environments.

[0004] Therefore, those skilled in the art have provided a low-voltage anti-islanding device suitable for installation in various environments to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a low-voltage anti-islanding device suitable for installation in various environments, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0024] Please see Figure 1-7 A low-voltage anti-islanding device suitable for installation in various environments includes a low-voltage anti-islanding device 1. An installation mechanism 2 is provided on the outside of the low-voltage anti-islanding device 1. The installation mechanism 2 includes two first folding plates 203. A connecting strap 210 is fixedly connected to the inner wall of each first folding plate 203. Two Velcro straps 211 are fixedly connected to the outer surface of each connecting strap 210. Two sets of snap-fit ​​shells 9 are fixedly connected to the inner wall of each first folding plate 203. Two snap-fit ​​plates 10 are snapped into the interior of each set of snap-fit ​​shells 9. A limiting plate 8 is fixedly connected to the back of each set of snap-fit ​​plates 10. Through the snap-fit ​​plates 10, snap-fit ​​shells 9 and limiting plates 8, the connecting straps 210 can be easily limited to prevent messy situations.

[0025] The inner wall of the low-pressure anti-islanding device 1 is fixedly connected with a soft cotton pad 204. The front of each first folding plate 203 is in contact with the back of the soft cotton pad 204. The back of each first folding plate 203 is fixedly and movably hinged with a second folding plate 202. The outer surface of each second folding plate 202 is movably hinged with the inner wall of the low-pressure anti-islanding device 1. A rubber pad 7 is provided on the outer side of each limiting plate 8. The outer surface of each rubber pad 7 is fixedly connected with the outer surface of the limiting plate 8. The rubber pad 7 can increase the anti-slip properties of the limiting plate 8 and make it convenient for installers to open the limiting plate 8.

[0026] The inner wall of the low-pressure anti-islanding device 1 has two mounting plates 209 that are hinged to each other. Two threaded holes 208 are opened on the side of the two mounting plates 209 that are far apart from each other. The bottom surface of the low-pressure anti-islanding device 1 is fixedly connected to the first bottom shell 207. Each second folding plate 202 has an auxiliary sticker 6 on its outer side. The outer surface of each auxiliary sticker 6 is fixedly connected to the outer surface of the second folding plate 202. The second folding plate 202 can be opened easily through the auxiliary sticker 6, so as to achieve a better use effect.

[0027] The inner wall of the first base shell 207 is fixedly connected with an adhesive 206. A second base shell 201 is provided below the first base shell 207. A PVC film 205 is fixedly connected to the inner wall of the second base shell 201. Each mounting plate 209 has an anti-slip pad 3 on its outer side. The sides of the two anti-slip pads 3 that are close to each other are fixedly connected to the sides of the two mounting plates 209 that are far apart from each other. The anti-slip pads 3 can increase the friction between the mounting plate 209 and the wall or mounting surface to prevent slipping.

[0028] The upper surface of the PVC film 205 and the upper surface of the second bottom shell 201 are in contact with the bottom surface of the adhesive 206 and the bottom surface of the first bottom shell 207, respectively. The bottom surface of the first bottom shell 207 is provided with two sets of snap-fit ​​grooves 5. Each set of snap-fit ​​grooves 5 has two snap-fit ​​blocks 4 snapped into it. The bottom end of each snap-fit ​​block 4 is fixedly connected to the upper surface of the second bottom shell 201. Through the snap-fit ​​blocks 4 and the snap-fit ​​grooves 5, the first bottom shell 207 and the second bottom shell 201 can be easily snapped together, which is convenient for installation.

[0029] The working principle of this utility model is as follows: When the low-pressure anti-islanding device 1 needs to be placed directly on a horizontal surface, the bottom is directly supported by the second base shell 201. When the low-pressure anti-islanding device 1 needs to be positioned on a horizontal surface, the second base shell 201 is directly removed, allowing the adhesive 206 to adhere directly to the horizontal surface, ensuring the overall stability of the low-pressure anti-islanding device 1. When the low-pressure anti-islanding device 1 needs to be fixed to a wall, the two mounting plates 209 are opened, allowing the back of the mounting plates 209 to contact the wall. Bolts are then used with threaded holes 208 to directly fix the low-pressure anti-islanding device 1 to the wall, increasing the applicability of the installation. When the low-pressure anti-islanding device 1 needs to be fixed to a rectangular column... At this time, directly open the two second folding plates 202 on the back, and then flip the first folding plate 203 so that the first folding plate 203 and the second folding plate 202 are on the same horizontal plane as the side of the low-voltage anti-islanding device 1. Then open the limiting plate 8, take out the connecting strap 210, and connect and fix it through the Velcro 211 on the surface of the connecting strap 210. Since the back of the low-voltage anti-islanding device 1 is connected with a soft cotton pad 204, it can increase the friction between the low-voltage anti-islanding device 1 and the rectangular column, preventing slippage. It is effectively applicable to the installation of the low-voltage anti-islanding device 1 in various environments, avoiding the problem that the anti-islanding device is limited by the installation environment and lacks a certain installation structure, which leads to the need to equip the anti-islanding device with corresponding installation auxiliary structures in different environments.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
