Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to a visual switchgear emergency tripping remote control device. Background Technology

[0002] When a control circuit disconnection fault occurs in the switchgear, substation operators need to go to the site for emergency tripping. Currently, switchgear cabinets are divided into two types: those with a built-in emergency trip button and those without. Switchgear with a built-in emergency trip button can be tripped by pressing the button while the cabinet door is closed. Switchgear without an emergency trip button requires opening the door and pressing the trip button inside the cabinet. Therefore, regardless of whether the switchgear cabinet door has an emergency trip button, the operator must be close to the switchgear to perform the operation.

[0003] Chinese invention patent CN108648929B discloses a portable remote emergency tripping device, which is installed using a suction cup electromagnet and uses an impact electromagnet to press the emergency tripping button. This not only ensures the personal safety of the operator when operating the switch, but also speeds up the emergency handling of remote operation failure of the switch. However, when the device is in standby mode, it still needs to continuously supply power to the suction cup electromagnet, resulting in energy waste. In addition, it is inconvenient to manually disconnect the power when there is no fault and normal power disconnection is required for maintenance, which affects normal use. Summary of the Invention

The protective shell 4 is installed on the outer wall of the cabinet 1. Mounting plates 2 are provided around the protective shell 4. The four corners of the mounting plates 2 are connected to the outer wall of the cabinet 1 by mounting screws 3. During installation, the mounting plates 2 are installed on the cabinet 1 using the mounting screws 3. The mounting screws 3 can be self-tapping screws, or they can be installed by drilling holes in the cabinet 1 and using the mounting screws 3 in conjunction with nuts. The outer wall of the cabinet 1 is provided with a trip button 23 located inside the protective shell 4. A control block 34 is provided in the middle of the top of the protective shell 4. A remote control switch 14 is provided on one side of the control block 34. The remote control switch 14 can use the Yibaite CE31-BxxR 4G Yunruineng remote control switch, which can be controlled through a mobile APP. It has a built-in data card, adopts industrial-grade standard design, and has functions such as anti-mildew and anti-moisture. like Figure 1 and Figure 4 As shown, the front side wall of the protective shell 4 is provided with a hinge groove 5, the bottom of the hinge groove 5 is provided with a pressure control groove 6, a pressing block 8 is slidably connected to the middle of the pressure control groove 6, a pressing column 24 is installed on the side of the pressing block 8 near the trip button 23, the upper and lower sides of the side wall of the protective shell 4 are provided with sliding grooves 25, and the upper and lower ends of the pressing block 8 are provided with sliding blocks 26 that slide inside the sliding grooves 25. When pressing, the sliding blocks 26 slide inside the sliding grooves 25, causing the pressing block 8 and the pressing column 24 to move, and the pressing column 24 is used to press the pressing point of the trip button 23. like Figure 1 Figure 3 As shown, a hinge plate 9 is hinged to the top of the hinge slot 5. A cast iron block 10 is fixedly connected to the movable end of the hinge plate 9. Two circular spring holes are symmetrically opened on the front side of the control block 34. A pop-out spring 20 is provided inside the spring hole to pop the hinge plate 9 outward. After the hinge plate 9 is released, the elastic force of the pop-out spring 20 can quickly pop the hinge plate 9 outward. like Figure 1 A triangular plate 11 is provided on one side of the cast iron block 10 to press and move the pressing block 8. Two permanent magnets 7 are symmetrically arranged on both sides of the inner wall of the pressure control groove 6. Two rubber pads are symmetrically arranged on both sides of the cast iron block 10. A finger groove 12 is opened on one side of the cast iron block 10. An iron block 32 is provided on one side of the hook 17. An electromagnet 13 that attracts the iron block 32 is fixedly connected to the side wall of the control block 34. The electromagnet 13 is electrically connected to the remote control switch 14 through a wire. A pull-back spring 33 is provided in the middle of the other side of the hook 17. The end of the pull-back spring 33 is fixedly connected to the side wall of the snap-fit ​​groove 16. Connect the external wire of the remote control switch 14 to the power supply. When operating via remote control, the remote control switch 14 receives a signal and supplies power to the electromagnet 13 through the wire. Figure 3 and Figure 6As shown, after the electromagnet 13 generates a magnetic force, it attracts the iron block 32 through the magnetic force, which can move the hook 17. At the same time, the pull spring 33 will also be stretched. After the hook 17 separates from the latch hook 15.

[0020] A snap hook 15 is provided in the middle of the hinge plate 9, and a snap groove 16 is provided on the front side wall of the control block 34. An iron block 32 is provided inside the snap groove 16.

[0021] like Figure 4 and Figure 5 As shown, a threaded rod 28 is connected to the middle of the pressing column 24 via a connecting bearing 27. A threaded hole 29 that mates with the threaded rod 28 is provided in the middle of the pressing block 8. Two cylinders 30 are symmetrically arranged on the upper and lower sides of the pressing column 24. Two circular holes 31 for inserting the cylinders 30 are symmetrically arranged on the pressing block 8. When adjusting the position of the pressing column 24, the threaded rod 28 can be rotated with a screwdriver to gradually extend out of the threaded hole 29. As the threaded rod 28 gradually extends, the cylinders 30 will also extend out of the circular holes 31, thereby making the pressing column 24 stably close to the pressed position on the trip button 23. After the pressing column 24 contacts the pressed position, the pressing block 8 will slide outward, using the sliding groove 25 and the sliding block 26 for limiting, until the sliding block 26 slides to the end position of the sliding groove 25. At this time, the surface of the pressing block 8 is flush with the pressure control groove 6.

[0022] The top of the control block 34 is provided with a control groove 18, and a push block 19 is movably connected inside the control groove 18. The top of the hook 17 is fixedly connected to the push block 19. The side wall of the control groove 18 is provided with a limit groove 21. Limit blocks 22 located inside the limit groove 21 are symmetrically arranged on both sides of the push block 19. When manual operation is required for maintenance, the hook 17 is moved horizontally by manually moving the push block 19, so that the hook 17 is directly separated from the latch hook 15. The hinge plate 9 can then be ejected outward under the action of the pop-out spring 20. After releasing the push block 19, the hook 17 can be pulled back directly by the pull-back spring 33.

[0023] The specific steps and principles of using this device are as follows: When in use, align the position of the pressing column 24 with the pressing position of the trip button 23, and use the mounting screws 3 to install the mounting plate 2 on the cabinet 1. The mounting screws 3 can be self-tapping screws, or the mounting screws 3 can be installed by drilling holes in the cabinet 1 and using the mounting screws 3 and nuts together. After the device is installed, the threaded rod 28 is located at the deepest position inside the threaded hole 29. By turning the threaded rod 28 with a screwdriver, the threaded rod 28 can be gradually extended out of the threaded hole 29. As the threaded rod 28 gradually extends, the cylinder 30 will also extend out of the round hole 31, so that the pressing column 24 is stably close to the pressed position on the trip button 23. After the pressing column 24 contacts the pressed position, the pressing block 8 will slide outward, using the sliding groove 25 and the sliding block 26 to limit the movement until the sliding block 26 slides to the end position of the sliding groove 25. At this time, the surface of the pressing block 8 is flush with the pressure control groove 6.

[0024] Connect the external wire of the remote control switch 14 to the power supply. When operating via remote control, the remote control switch 14 receives a signal and supplies power to the electromagnet 13 through the wire. Figure 3 and Figure 6 As shown, after the electromagnet 13 generates magnetic force, it attracts the iron block 32 through magnetic force, which can move the hook 17. At the same time, the pull spring 33 will also be stretched. After the hook 17 separates from the latch hook 15, the hinge plate 9 will be directly ejected under the action of the pop-out spring 20. The cast iron block 10 at the end of the hinge plate 9 rotates downward to accelerate. The speed and weight make the triangular plate 11 press the pressing block 8 in. At the same time, with the attraction force of the permanent magnet 7 on the cast iron block 10, the pressing block 8 can be kept in the position after being pressed, so as to achieve the purpose of remote control. When the device needs to be restored, the remote control switch 14 is turned off by remote control, so that the hook 17 is pulled back by the pull spring 33. The cast iron block 10 is pulled open by inserting a finger into the finger groove 12. The pressing column 24 is pushed by the spring force inside the trip button 23 to restore the pressing block 8 to its original position. At the same time, the hinge plate 9 is rotated upward so that the locking hook 15 re-enters the locking groove 16. After the hook 17 is engaged with the locking hook 15, the position of the hinge plate 9 can be fixed again. When manual operation is required for maintenance, the hook 17 can be moved horizontally by manually moving the push block 19, thereby separating the hook 17 from the snap hook 15. This allows the hinge plate 9 to pop outward under the action of the pop-out spring 20. After releasing the push block 19, the hook 17 can be pulled back directly by the pull-back spring 33.
