Description

Technical Field

[0001] This utility model relates to the field of power system switchgear accessories, and specifically to an anti-interference device for the operating handle of a high-voltage disconnect switch and the cabinet door. Background Technology

[0002] In recent years, high-voltage disconnect switches have been increasingly widely used in power systems, and their advantages such as reliability and ease of operation have become increasingly apparent. Disconnect switches are characterized by long service life and simple operation; the switching action can be completed simply by moving a handle. The switch status is clearly visible, allowing operators to clearly see the open or closed state from a distance, and maintenance is convenient. Therefore, the application of high-voltage disconnect switches in power supply systems is growing rapidly.

[0003] However, with the widespread use of high-voltage disconnect switches, some technical problems have gradually emerged. One prominent issue is interference between the operating handle of the high-voltage disconnect switch and the cabinet door. Specifically, the operating handle of the high-voltage disconnect switch extends too far, causing interference with the transformer substation door and preventing the door from closing properly. This not only affects the normal use of the equipment but may also pose a safety hazard.

[0004] The existence of this interference problem seriously affects the practicality and reliability of high-voltage disconnect switches. First, it restricts normal operation, potentially preventing operators from closing the cabinet door in a timely manner and increasing the risk of equipment exposure to the external environment. Second, frequent interference can damage the operating handle or cabinet door, increasing maintenance costs. Furthermore, this problem can also affect the safety and stability of the entire power supply system.

[0005] Therefore, effectively resolving the interference between the operating handle of a high-voltage disconnector and the cabinet door has become a pressing technical challenge. Developing a device that can effectively prevent interference without affecting the normal operation of the disconnector is of great significance for improving the practicality and reliability of high-voltage disconnectors. Utility Model Content

[0006] To overcome the aforementioned problems in the prior art, this utility model provides an anti-interference device for the operating handle of a high-voltage disconnect switch and the cabinet door. It fundamentally solves the problem of the extended length of the operating handle, and changes the handle fixing method to a rotary insertion method. When operation is required, the handle is screwed in and fixed. After the operation is completed, the handle can be removed, effectively preventing interference between the operating handle and the cabinet door, and improving the practicality and reliability of the high-voltage disconnect switch.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an anti-interference device for the operating handle of a high-voltage disconnect switch and the cabinet door, comprising two front mounting plates and two rear mounting plates located at the rear end of the front mounting plates. One end of the operating handle is movably connected between the two front mounting plates by a first fixing pin, which can be freely disassembled. The front end of a first transmission plate is hinged to one end of the operating handle. Two second transmission plates are hinged to the inner sides of the two rear mounting plates, and a third transmission plate is hinged between the two second transmission plates. A third fixing pin passes through the edge of the two second transmission plates, and the first transmission plate passes through the space between the two rear mounting plates and is connected to the third fixing pin.

[0008] Furthermore, the front mounting plate has multiple insertion holes for inserting the first fixing pin, which facilitates adjusting the fixing position of the operating handle.

[0009] The two second transmission plates and the third transmission plate are all connected to the second fixing pin between the two rear mounting plates.

[0010] This invention effectively solves the interference problem between the operating handle and the cabinet door through this structural design, thereby effectively preventing interference between the operating handle and the cabinet door and improving the practicality and reliability of the high-voltage disconnect switch.

[0015] See appendix Figure 1 and Figure 2This is an embodiment of the present invention, an anti-interference device for the operating handle 1 of a high-voltage disconnect switch and the cabinet door, including two front mounting plates 7 and two rear mounting plates 8 located at the rear end of the front mounting plates 7. One end of the operating handle 1 is movably connected between the two front mounting plates 7 by a first fixing pin 2, which can be freely disassembled; the front end of a first transmission plate 3 is hinged to one end of the operating handle 1; two second transmission plates 5 are hinged to the inner side of the two rear mounting plates 8, and a third transmission plate 6 is hinged between the two second transmission plates 5. Both the two second transmission plates 5 and the third transmission plate 6 are connected to the second fixing pin 9 between the two rear mounting plates 8. A third fixing pin 4 is connected to the edge of the two second transmission plates 5, and the first transmission plate 3 passes between the two rear mounting plates 8 and is connected to the third fixing pin 4.

[0016] To address the problem of excessively long extension of the high-voltage disconnect switch operating handle 1 interfering with the transformer substation door, this utility model provides an anti-interference device. By setting multiple mounting plates and transmission plates between the operating handle 1 and the cabinet door, the range of motion of the operating handle 1 is restricted, thereby avoiding interference between the handle and the transformer substation door. Through the free disassembly and connection of the first fixing pin 2 and the second fixing pin 9, the device can be flexibly adjusted and installed, ensuring convenient operation and equipment reliability, which is significantly superior to existing technical solutions.

[0017] Specifically, the free disassembly of the first fixing pin 2 allows the operating handle 1 to be flexibly installed and adjusted, facilitating operation and maintenance. The first transmission plate 3 is hinged to the operating handle 1, enabling the movement of the operating handle 1 to be transmitted to the transmission plate system. The hinged structure between the second transmission plate 5 and the third transmission plate 6 allows the transmission plate system to flexibly adjust its position and angle, thereby avoiding interference between the operating handle 1 and the transformer substation door. The connection of the second fixing pin 9 and the third fixing pin 4 ensures a stable connection of the transmission plate system, guaranteeing the reliability and durability of the device.

[0018] In solving the interference problem between the operating handle 1 and the cabinet door using the technical solution of this application, the operating handle 1 is movably connected between the two front mounting plates 7 via a first fixing pin 2. The free disassembly of the first fixing pin 2 allows the operating handle 1 to be flexibly installed and adjusted. The front end of the first transmission plate 3 is hinged to the operating handle 1, enabling the movement of the operating handle 1 to be transmitted to the second transmission plate 5. Two second transmission plates 5 are hinged to the inner sides of the two rear mounting plates 8, and a third transmission plate 6 is hinged between the two second transmission plates 5, transmitting the movement to the third transmission plate 6. Thus, the interference problem between the operating handle 1 and the cabinet door is effectively solved, ensuring the normal closing of the transformer substation door and the reliable operation of the equipment.

[0019] The operating handle 1 in this utility model is designed to be detachable. When the operating handle 1 is not needed, it can be removed from the disconnect switch without affecting the opening and closing of the transformer substation door. When disconnection is required, the handle can be inserted into the disconnect switch for easy operation by the operator. The quick disassembly and installation of the disconnect switch handle greatly saves space and effectively avoids interference with the door panel. (Method for disassembling the operating handle 1: disassembly by removing the first fixing pin 2).
