DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] The present application embodiment discloses a gas-filled high-voltage switchgear for use in high-altitude areas. Figure 1 An inflatable high-voltage switchgear for high-altitude areas includes a cabinet body 1 for accommodating electrical equipment. One side of the cabinet body 1 is open, and a cabinet door 2 is arranged at the opening. An opening component 3 is arranged between the cabinet door 2 and the cabinet body 1. The arrangement of the opening component 3 enables the cabinet door 2 to rotate relative to the cabinet body 1, and the extension direction of the rotation axis is parallel to the height direction of the cabinet body 1.

[0034] Specifically, the cabinet body 1 is composed of a main frame and several panels. The main frame is a roughly cubic structure. There are five panels, two of which are installed on the top and bottom of the main frame, and the remaining three panels are installed on the three sides of the main frame, thereby forming an opening on one side of the cabinet body 1.

[0035] Furthermore, a mounting seat 6 is connected to one side of the cabinet body 1 on which the cabinet door 2 is provided, and a shaft rod 7 is rotatably connected to the mounting seat 6. A shaft hole is provided on one side of the cabinet door 2 facing the mounting seat 6, and one end of the shaft rod 7 passes through the shaft hole and extends vertically. Preferably, the shaft rod 7 is arranged on a side away from the middle of the cabinet body 1, and the central axis of the shaft rod 7 coincides with the rotation axis of the cabinet door 2. When the cabinet door 2 rotates under the action of the opening assembly 3, the shaft rod 7 plays a role of auxiliary limiting, thereby improving the stability of the cabinet door 2 during rotation. Preferably, two mounting seats 6 and two shaft rods 7 are respectively provided, and are symmetrically arranged above and below the cabinet door 2 to further improve stability. The side of the cabinet door 2 on which the shaft rod 7 is provided is a fixed side, and the other opposite side is a movable side.

[0036] Reference Figure 2The opening assembly 3 includes a slide rail 31, a sliding connector 32 and a first connecting rod 33, wherein the slide rail 31 is horizontally laid on the side of the cabinet door 2 facing the cabinet body 1, the sliding connector 32 is arranged in cooperation with the slide rail 31 and can slide along the extension direction of the slide rail 31, and one end of the first connecting rod 33 is hinged to the sliding connector 32, and the other end is hinged to the cabinet body 1. With the above structure, when the staff applies an external force away from the cabinet body 1 to the movable side of the cabinet door 2, the cabinet door 2 rotates in the direction away from the cabinet body 1, and the sliding connector 32 slides in the slide rail 31, and the connecting rod moves accordingly. The sliding connector 32 has two extreme positions on the slide rail 31 as the rotation angle of the cabinet door 2 changes. When the sliding connector 32 is in the first extreme position, the angle between the cabinet door 2 and the cabinet body 1 is 0°, and the cabinet door 2 is in a closed state; when the sliding connector 32 is in the second extreme position, the angle between the cabinet door 2 and the cabinet body 1 is greater than 90°, and the cabinet door 2 is in an open state.

[0037] Reference Figure 2 and Figure 4 In order to fix the position of the cabinet door 2 after opening and prevent the cabinet door 2 from swinging randomly due to strong wind during maintenance, a locking mechanism 4 is provided on the cabinet door 2. The locking mechanism 4 can limit the sliding connection member 32 moving to the second extreme position, so that the sliding connection member 32 cannot slide to the first extreme position. First, a vertically penetrating lock hole is provided on the slide rail 31. The lock hole is provided on the side of the second extreme position close to the first extreme position, and a vertically extending lock sleeve 5 is formed on the surface of the slide rail 31. The above-mentioned locking mechanism 4 includes a locking rod 41 slidably provided in the locking sleeve 5, and a driving component 42 that can drive the locking rod 41 to extend into the lock hole or retract.

[0038] When the locking rod 41 extends into the lock hole, the sliding channel of the sliding connector 32 to the first limit position is cut off, so that the sliding connector 32 cannot move from the second limit position to the first limit position, preventing the cabinet door 2 from closing during maintenance.

[0039] Further, see Figure 6 The driving assembly 42 includes a push rod 421, a second connecting rod 422 and a first spring 423. A horizontally extending sliding sleeve is provided on the side of the cabinet door 2 facing the cabinet body 1. The push rod 421 is inserted into the sliding sleeve and can slide relative to the sliding sleeve. The second connecting rod 422 is rotatably connected to one end of the push rod 421, and the other end of the second connecting rod 422 is rotatably connected to the locking rod 41. The first spring 423 is sleeved on the surface of the push rod 421.

[0040] With the above structure, when the first spring 423 is in a naturally extended state, the second connecting rod 422 and the locking rod 41 are in the same straight line, and the locking rod 41 extends into the lock hole; when the push rod 421 is pushed, the first spring 423 is compressed, and the angle between the second connecting rod 422 and the locking rod 41 changes, causing the locking rod 41 to retract, and the channel for the sliding connection 32 to slide to the first extreme position is opened, so that the cabinet door 2 can be closed normally.

[0041] Reference Figure 3 When the cabinet door 2 rotates, the sliding connector 32 also has a third extreme position, which is located on the side of the second extreme position away from the first extreme position. A lubrication component 8 is provided corresponding to the third extreme position to improve the lubrication effect between the sliding connector 32 and the slide rail 31.

[0042] Specifically, the lubrication assembly 8 includes a container 81 (generally a box-shaped or bottle-shaped structure) arranged on the side of the cabinet door 2 facing the cabinet body 1. The container 81 is arranged above the slide rail 31 and is filled with lubricating oil. An oil hole is opened on the side of the container 81 facing the slide rail 31. The lubrication assembly 8 also includes a sealing member 82 arranged at the oil hole. When the sealing member 82 is not subject to external force, the oil hole can be closed and the lubricating oil is retained in the container 81.

[0043] Further, see Figure 5 The sealing member 82 includes a plug 821 and a sealing rod 822. The plug 821 is arranged in the container 81, and the diameter of the plug 821 is larger than the diameter of the oil hole. The sealing rod 822 is arranged on the side of the plug 821 facing the slide rail 31, and the diameter of the sealing rod 822 is slightly smaller than the diameter of the oil hole, so that the sealing rod 822 can slide up and down in the oil hole, and an oil groove 8221 for the flow of lubricating oil is opened on the surface of the sealing rod 822.

[0044] Furthermore, a through hole is provided on one side of the slide rail 31 facing the container 81. When the oil hole is in a closed state, the blocking rod 822 partially extends into the slide rail 31 through the through hole. When the sliding connector 32 moves to the third extreme position, the blocking rod 822 will be squeezed to move the blocking rod 822 upward, and the plug 821 will move upward accordingly. At this time, the lubricating oil in the container 81 can flow downward through the oil hole and the oil groove 8221 opened on the surface of the blocking rod 822, and flow through the through hole along the axial direction of the blocking rod 822 to the slide rail 31. When the sliding connector 32 slides along the slide rail 31, the lubricating oil can be applied to various parts of the slide rail 31 to lubricate the slide rail 31 and the sliding connector 32.

[0045] Reference Figure 5The lubrication assembly 8 further includes a second spring 83, which is sleeved on the surface of the blocking rod 822. When the second spring 83 naturally extends, the blocking rod 822 extends into the slide rail 31, and when the sliding connector 32 squeezes the blocking rod 822 to move upward, the second spring 83 is compressed. When the blocking rod 822 is not subjected to external force, the second spring 83 can restore its deformation, so that the blocking rod 822 and the plug 821 are reset, and the oil hole is re-sealed.

[0046] During normal operation, the cabinet door 2 is opened and closed to cause the sliding connector 32 to move between the second limit position and the first limit position. When the movement of the sliding connector 32 becomes unsmooth or stuck, the cabinet door 2 is rotated to move the sliding connector 32 to the third limit position, so that the lubricating oil acts between the slide rail 31 and the sliding connector 32.

[0047] The implementation principle of an inflatable high-voltage switchgear for high-altitude areas in an embodiment of the present application is as follows: initially, the second connecting rod 422 and the locking rod 41 are in the same straight line, and the locking rod 41 extends into the lock hole. When maintenance is required, the cabinet door 2 is rotated by a certain angle, and the sliding connection member 32 moves from the first extreme position to the second extreme position. After rotating by a certain angle, the staff's hand extends between the cabinet body 1 and the cabinet door 2, and pushes the push rod 421, so that the second connecting rod 422 drives the locking rod 41 to retract, and at the same time rotates the cabinet door 2 to move the sliding connection member 32 to the second extreme position, and then releases the push rod 421, and the second spring 83 drives the second connecting rod 422 and the locking rod 41 to reset, so that the sliding connection member 32 cannot move from the second extreme position to the first extreme position, thereby preventing the cabinet door 2 from suddenly moving during maintenance.

[0048] After the inspection is completed, the push rod 421 is pushed again to retract the locking rod 41, and the cabinet door 2 is rotated to move the sliding connection member 32 from the second limit position to the first limit position, and the cabinet door 2 is closed.

[0049] When the sliding connector 32 gets stuck or becomes unsmooth when moving along the slide rail 31, the cabinet door 2 is rotated to move the sliding connector 32 to the third extreme position. At this time, the sliding connector 32 will squeeze the blocking rod 822 upward, and the blocking rod 822 drives the plug 821 to move upward, so that the oil hole is connected to the oil groove 8221 opened on the surface of the blocking rod 822, and the lubricating oil flows downward along the oil groove 8221 and finally flows into the slide rail 31, acting between the sliding connector 32 and the slide rail 31. By rotating the cabinet door 2 back and forth, the sliding connector 32 moves back and forth on the slide rail 31, so that the lubricating oil is applied to various parts of the slide rail 31 to achieve lubrication.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
