Description

Technical Field

[0001] The invention relates to the technical field of manual release gate equipment, and in particular to an anti-mistouch device for a release gate of a power distribution cabinet. Background Art

[0002] The anti-accidental touch device for the separation gate of the distribution cabinet is a safety device used to prevent the separation gate of the distribution cabinet from being touched by mistake. Its function is to cut off the power supply of the separation gate of the distribution cabinet in time when personnel touch or operate incorrectly to ensure the safety of personnel and equipment. The use of the anti-accidental touch device for the separation gate of the distribution cabinet can effectively prevent accidents caused by incorrect operation. It is usually used in distribution cabinets in high-voltage power systems to control and isolate power supplies. The anti-accidental touch device for the separation gate can also include other safety measures, such as being equipped with protective covers, indicator lights or sound prompts to enhance the operator's perception and warning of the state of the separation gate. This device is usually installed on the switches and isolating switches of high-voltage or low-voltage distribution cabinets. When the operator needs to inspect or maintain the distribution cabinet, the separation gate must be cut off first to disconnect the circuit between the power supply and the distribution cabinet to ensure that the distribution cabinet is in a power-free state. The anti-accidental touch device for the separation gate of the distribution cabinet is an important equipment that ensures the safety of operators and prevents electrical accidents through mechanical or electrical means.

[0003] In the prior art, some technicians have installed a shell or cover on the outside of the separation gate to protect the knife switch to prevent the knife switch from accidentally touching it from the outside and causing unexpected opening and closing. However, since the switch or knife switch is mostly fixed and installed in the cabinet, the shell or cover may accidentally touch the switch knife switch when it falls, and it may also accidentally touch the switch knife switch due to improper operation or mistakes. When the external vibration is large, such as a large impact, the shell or cover cannot affect the separation gate. At this time, the separation gate is prone to unexpected opening and closing under vibration, and water vapor is easy to contact the separation gate in humid weather, which will accelerate the aging of the separation gate.

[0017] 1. A device for preventing accidental touch of the separation gate of a distribution cabinet. When the operator needs to close the distribution cabinet, the protective cover and the protective shell are merged through the hinged rod and the L-shaped connecting frame. When the protective cover is rotated to a certain position, the U-shaped clamp is inserted into the slot hole of the slot fixing block and rotated, so that the slot fixing block clamps the U-shaped clamp to prevent the protective cover from moving, thereby closing the protective cover and the protective shell to prevent the user from touching it by mistake.

[0018] 2.

[0019] 3. A device for preventing accidental touch of the separation gate of a power distribution cabinet, when the protective cover moves, the protective cover drives the hinge to move, thereby pushing the plate to move, and the sliding rod slides in the sliding groove. When the sliding rod slides to a certain position, the pushing plate pushes the toothed plate to move, and the convex sliding block slides on the groove plate, thereby limiting the movement of the toothed plate. When the toothed plate moves, the toothed plate and the gear are engaged to cause the gear to drive the rotating shaft to rotate, and the rotating shaft drives the threaded rotating rod to rotate, so that the moving rod moves outward through the thread of the threaded rotating rod, and the sliding block slides on the fixed sliding rod to limit the moving rod.

When the power switch needs to be cut off, the U-shaped push plate is pressed to make the connecting rod drive the special-shaped push rod to move, so that the connecting frame drives the moving sliding block to move. When the moving sliding block moves to the two ends of the supporting slide bar, the moving plate drives the pull rod to descend, so that the separation gate body can be released from the limit, thereby pulling the separation gate body, which has the advantage of good stability and can make the separation gate body switch more stable and safe.

[0044] When in use, when the operator needs to close the power distribution cabinet, the protective cover 105 is combined with the protective shell 101 through the hinge rod 103 and the L-shaped connecting frame 104. When the protective cover 105 is rotated to a certain position, the U-shaped clamp 108 is inserted into the slot hole of the slot fixing clamp block 109 and rotates, so that the slot fixing clamp block 109 clamps the U-shaped clamp 108 to prevent the protective cover 105 from moving, so that the protective cover 105 and the protective shell 101 are closed to avoid accidental touch by the user.

[0046] When the operator needs to inspect or maintain the distribution cabinet, the first thing to do is to cut off the separation gate to disconnect the circuit between the power supply and the distribution cabinet to ensure that the distribution cabinet is in a power-free state. The protective cover 105 is opened to vibrate the protective shell 101, so that the separation gate body 24 will be opened and closed by mistake due to the vibration. When it is opened, it is easy for the staff to accidentally touch the separation gate body 24 during work. When the protective cover 105 is opened, the connecting spring 503 pushes the moving sliding block 502 to move on the supporting sliding rod 501, so that the moving sliding block 502 moves to the middle of the supporting sliding rod 501, so that the moving plate 601 pushes the supporting member 603 to rise, and the square sliding rod 604 is on the limiting sliding plate 605. The support member 603 can limit the separation gate body 24 to prevent the staff from accidentally touching the separation gate body 24 during work, and the safety guarantee can be greatly improved.
