[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] like Figure 1-Figure 6 As shown, the utility model provides a high-voltage switch cabinet, including a shell 1, a cabinet door 2 is hinged on the side wall of the shell 1, a humidity sensor 3 is fixedly connected to the side wall of the cabinet door 2, a temperature sensor 4 is fixedly connected to the side wall of the cabinet door 2, an exhaust fan 5 is fixedly connected inside the shell 1, a plurality of air holes 6 are opened on the side wall of the shell 1, an auxiliary structure 8 is provided on the side wall of the shell 1, and a filtering structure 9 is provided on the inner wall of the shell 1.

[0034] The specific settings and functions of the auxiliary structure 8 and the filtering structure 9 are described in detail below.

[0035] like Figure 2-Figure 4 As shown, the auxiliary structure 8 includes a side plate 81, which is rotatably connected to the housing 1, a limit block 82 is fixedly connected to the surface of the side plate 81, a round tube 83 is fixedly connected to the inner wall of the housing 1, and a limit rod 84 is slidably connected to the inner wall of the round tube 83. The size of the limit rod 84 matches the size of the limit block 82. A spring 85 is fixedly connected to the lower end of the limit rod 84, and one end of the spring 85 is fixedly connected to the housing 1. The surface of the limit block 82 is provided with an inclined surface 88. When the spring 85 is extended, the limit rod 84 will With the help of the tension of the spring 85, it automatically slides upward and is inserted into the limit block 82. The arc surface of the limit rod 84 is fixedly connected with a pressure plate 86. The pressure plate 86 is slidably connected to the round tube 83. Pressing the pressure plate 86 downward will drive the limit rod 84 to slide downward. The arc surface of the round tube 83 is fixedly connected with a buffer ring 87. The buffer ring 87 is a rubber ring. The side plate 81 will contact the buffer ring 87 when it rotates. The buffer ring 87 made of rubber material can slow down the rotation speed of the side plate 81, thereby buffering the side plate 81.

[0036] like Figure 5 and Figure 6As shown, the filter structure 9 includes a rotating frame 91, which is rotatably connected to the outer shell 1, and a filter plate 92 is slidably connected to the surface of the rotating frame 91. The size of the filter plate 92 is adapted to the size of the air vent 6. A baffle 93 is rotatably connected to the inner wall of the outer shell 1, and the baffle 93 is slidably connected to the rotating frame 91. A clamping frame 94 is fixedly connected to the surface of the rotating frame 91, and the clamping frame 94 is clamped and connected to the filter plate 92. The filter plate 92 is clamped with the clamping frame 94, and the clamping frame 94 reaches the position of limiting the filter plate 92, thereby preventing the filter plate 92 from sliding downward along the surface of the rotating frame 91 and being misaligned with the air vent 6 when the rotating frame 91 is subsequently rotated. A sealing ring 95 is fixedly connected to the surface of the filter plate 92, and the sealing ring 95 abuts against the inner wall of the outer shell 1. The sealing ring 95 can improve the sealing between the filter plate 92 and the outer shell 1, thereby ensuring that the filter plate 92 can filter the air normally.

[0037] Its overall working principle is that the mounting frame 7 is used to install high-voltage electrical equipment, the temperature sensor 4 can monitor the temperature in the high-voltage switch cabinet in real time, and the humidity sensor 3 can monitor the humidity in the high-voltage switch cabinet in real time, so that the environmental status in the high-voltage switch cabinet can be intelligently grasped in real time, so that the high-voltage electrical equipment can operate normally and in a healthy manner. When it is necessary to inspect and repair the high-voltage electrical equipment, first open the cabinet door 2 and then press the pressure plate 86 downward. The pressure plate 86 will drive the limit rod 84 to slide downward, and the limit rod 84 will slide out of contact with the limit block 82. Then, the side plate 81 is rotated to open the side plate 81. At this time, the range of activities of the staff can be expanded, so that it is convenient for the staff to inspect and repair the high-voltage electrical equipment installed on the mounting frame 7, which improves the convenience during inspection and maintenance. After the inspection is completed, the side plate 81 is rotated in the opposite direction. The rotation of the side plate 81 will drive the limit block 82 to move. The movement of the limit block 82 will cause the inclined surface 88 of the limit block 82 to contact the limit rod 84. At this time, the limit block 82 will squeeze the limit rod 84, causing the limit rod 84 to slide downward along the inclined surface 88 of the limit block 82. The sliding of the limit rod 84 will compress the spring 85. The side plate 81 continues to rotate and contacts with the buffer ring 87. The buffer ring 87 made of rubber can slow down the rotation speed of the side plate 81, thereby buffering the side plate 81. When the limit block 82 is aligned with the limit rod 84, the spring 85 begins to stretch, and the limit rod 84 will slide upward with the help of the tension of the spring 85 and be inserted into the limit block 82. The limit rod 84 reaches the position of limiting the limit block 82, thereby limiting the position of the back plate.

[0038] When the filter structure 9 needs to be used, the filter plate 92 is engaged with the card frame 94, and the card frame 94 reaches the position of limiting the filter plate 92, so as to prevent the filter plate 92 from sliding downward along the surface of the rotating frame 91 and being misaligned with the air vent 6 when the rotating frame 91 is subsequently rotated. Then, the rotating frame 91 is rotated, and the rotating frame 91 drives the filter plate 92 to rotate. The rotation of the filter plate 92 causes the sealing ring 95 to abut against the inner wall of the housing 1. The sealing ring 95 can improve the sealing between the filter plate 92 and the housing 1, thereby ensuring that the filter plate 92 can filter the air normally. Then, the baffle plate 93 is rotated. When the baffle plate 93 contacts the rotating frame 91, the baffle plate 93 reaches the position of limiting the rotating frame 91, thereby limiting the position of the filter plate 92. When the exhaust fan 5 is turned on to speed up the flow of air in the outer shell 1, the air will flow into the outer shell 1 through the air vent 6. During this process, the filter plate 92 can filter foreign matter such as dust in the air to prevent foreign matter such as dust from adhering to the high-voltage electrical equipment and affecting the normal operation of the high-voltage electrical equipment, thereby improving the stability of the high-voltage switch cabinet during operation.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
