AI Technical Summary
In existing technologies, grounding wires pose safety hazards during use, potentially leading to personal or equipment safety risks, especially since they are difficult to monitor and operate effectively in both energized and de-energized states.
A substation anti-misoperation device was designed, including a control box, a threaded rod, a mechanical lock, and an electromagnetic lock. The device monitors the electrical status of the grounding wire through a wireless live display and allows manual removal of the grounding wire when the electromagnetic lock is opened, thus ensuring safety.
It enables safe monitoring and operation of the grounding wire, prevents misoperation, improves safety in use, and ensures the safety of staff.

[0002] The grounding wire is an important tool to ensure that power workers can work safely on power-off equipment and lines. It is also called the safety line or lifeline by our power workers. Once the protection of the grounding wire is lost during work, it may bring serious safety hazards to people or equipment. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a substation error prevention device.
[0004] The technical solution of the present invention is implemented as follows: a substation error prevention device includes a control box for placing a grounding wire, the control box includes a left side plate, a right side plate, a back plate and a top plate, a through hole is opened on the top plate, a threaded rod is rotatably connected inside the control box, the left side plate and the right side plate of the control box are fixedly connected with nuts, the threaded rod passes through the left side plate of the control box and is threadedly connected with the nut on the left side plate, the end of the grounding wire is connected to a grounding coil, the grounding coil passes through the through hole vertically downward, the grounding coil is sleeved on the threaded rod, and one end of the threaded rod is fixedly connected to a handwheel.
[0005] The other end of the threaded rod passes through the right side plate and extends to the outside of the right side plate. A through hole is opened in the circumference of the extended portion of the threaded rod located on the right side plate, and a mechanical lock is installed in the through hole.
[0006] A protective door is hinged at the front of the control box, an electromagnetic lock is installed between the protective door and the control box, a wireless charged display is also installed on the protective door, and the wireless charged display is electrically connected to the electromagnetic lock.
[0007] The wireless live display is provided with an indicator light A, an indicator light B and an indicator light C. The indicator light A, the indicator light B and the indicator light C are three-phase indicator lights. The wireless live display is also provided with a flashing warning light and an operation indicator light.
[0008] When the ground wire is energized, indicator lights A, B and C are all on, the operation indicator light is off, and the electromagnetic lock is in a closed state.
[0009] When the ground wire is not energized, indicator lights A, B and C are all off, the operation indicator light is on, and the electromagnetic lock is in the open state.
[0010] When the electromagnetic lock is in the open state, open the mechanical lock, turn the hand wheel, rotate the threaded rod, and move it to the left side, so that the grounding coil falls off and the grounding coil is taken out from the through hole.
[0011] The technical solution of the present invention has the following positive effects: the present invention is provided with a control box, the grounding wire is locked in the control box, and the grounding wire is monitored by a wireless charged display, and the uncharged electromagnetic lock will be automatically opened; after the mechanical lock is opened, the hand wheel is rotated to rotate the threaded rod, so that the grounding coil falls from the threaded rod, thereby removing the grounding wire and ensuring the safe grounding of the grounding wire. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a structural schematic diagram of the present invention.
[0013] Figure 2 Schematic diagram of the internal structure of the control box. DETAILED DESCRIPTION
[0014] like Figure 1-2 As shown, a substation error prevention device includes a control box 2 for placing a grounding wire 1, the control box 2 includes a left side plate 3, a right side plate 4, a back plate 5 and a top plate 6, a through hole 7 is opened on the top plate, a threaded rod 8 is rotatably connected in the control box 2, the left side plate 3 and the right side plate 4 of the control box 2 are fixedly connected with nuts 9, the threaded rod 8 passes through the left side plate 3 of the control box 2 and is threadedly connected with the nut 9 on the left side plate 3, the end of the grounding wire 1 is connected with a grounding coil 10, the grounding coil 10 passes through the through hole 7 vertically downward, the grounding coil 10 is sleeved on the threaded rod 8, and one end of the threaded rod 8 is fixedly connected with a hand wheel 11; specifically, the grounding wire 1 is locked in the control box, and the grounding coil of the grounding wire 1 enters the control box 2 from the position of the through hole 7, A protective door 13 is hinged at the front of the control box 2 , an electromagnetic lock 14 is installed between the protective door 13 and the control box 2 , and a wireless charged display 15 is also installed on the protective door 13 , and the wireless charged display 15 is electrically connected to the electromagnetic lock 14 .
