Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to an anti-electric shock protection device for a high-voltage switch cabinet. Background Art

[0002] High-voltage switchgear is a complete set of switchgear and control equipment. As a power center and main distribution device, it is mainly used for the control, monitoring, measurement and protection of power lines and major electrical equipment. It is often installed in substations and distribution rooms. In the existing high-voltage switchgear, for safety reasons, insulating rods are installed inside the high-voltage switchgear for insulation protection of the high-voltage conductive cabinet. The cabinet itself has no current during normal use, but when it is damaged, it will release a very high voltage to the outside, or because the equipment and guides of the high-voltage switchgear will wear out after long-term use. When the internal wires of the high-voltage switchgear are damaged, it may cause leakage in the cabinet, which is very dangerous and the effect of the insulating rods will be reduced. At this time, if pedestrians and maintenance workers touch the switchgear door, there will be a greater hidden danger, endangering personal safety.

[0003] After searching, Chinese Patent Publication (Announcement) No. CN220190130U discloses a high-voltage switch cabinet anti-electric shock protection device. The patent is provided with an isolation frame and a fixed door shaft. The isolation frame is made of insulating material and extends out of the cabinet body. When the cabinet door is in a closed state, it is separated from the distribution cabinet. The isolation sleeve prevents the leakage of electrical components such as wires and instruments from being transmitted to the cabinet door. The fixed door shaft and the rotating door shaft are made of insulating material to isolate the distribution cabinet from the cabinet door, thereby preventing electric shock accidents caused by people controlling the panel instruments on the cabinet door. However, during use, the cabinet body is difficult to insulate. When the components inside the cabinet body leak electricity, when a person touches the cabinet door, it can prevent electric shock, but it is difficult to prevent electric shock when touching the cabinet body. There are certain safety hazards. Therefore, it is necessary to design a high-voltage switch cabinet anti-electric shock protection device. Utility Model Content

When the silicone rubber shell 3 is sleeved on the outer surface of the cabinet 1, the cabinet 1 can be insulated, and the outer surface of the fixed block 10 is provided with a second insulating layer. When the cabinet door 11 is closed, the second magnetic strip 12 is magnetically attracted to the first magnetic strip 9 on the insulating frame 8, and under the action of the insulating frame 8, the cabinet door 11 is isolated from the cabinet 1. While the cabinet door 11 is protected from electric shock, the cabinet 1 can also be protected from electric shock to prevent electric shock from occurring when the staff touches the cabinet 1 or opens the cabinet door 11 due to leakage inside the cabinet 1.

[0026] In this embodiment, side frames 13 are fixedly connected to both sides of the top frame 7, a rotating drum 14 is provided on the inner surface of the side frame 13, both ends of the rotating drum 14 are threadedly connected with a second screw rod 15, one end of the second screw rod 15 passes through the inner surface of the side frame 13 and extends to both sides of the side frame 13, the second screw rod 15 is slidably connected to the side frame 13, and a top block 16 is fixedly connected to the upper surface of the top frame 7.

[0027] During specific use, the rotating drum 14 can perform threaded motion with the second screw rod 15 when rotating, thereby driving the movement of the second screw rod 15 , and the setting of the top block 16 can limit the fixing rod 17 .

[0028] In this embodiment, a fixing rod 17 is fixedly connected to one side of the outer surface of the second screw rod 15 , and the fixing rod 17 is slidably connected to the top block 16 .

[0029] During specific use, when the second screw 15 and the rotating drum 14 perform threaded motion, the second screw 15 can be limited due to the sliding connection between the fixed rod 17 and the top block 16, so that the two second screws 15 can be extended or retracted from the rotating drum 14 under the threaded motion of the rotating drum 14 and the second screw 15.

[0030] In this embodiment, a meshing wheel 18 is rotatably connected to the upper surface of the fixed cylinder 4 , and the meshing wheel 18 is threadedly connected to the first screw rod 6 .

[0031] During specific use, when the meshing wheel 18 is rotated, it can make a threaded motion with the first screw 6. Since the sliding motion of the first screw 6 and the through groove 5 limits the first screw 6, when the meshing wheel 18 and the first screw 6 threadably move, the first screw 6 can extend or retract from the fixed tube 4 and drive the top frame 7 to move up and down.

[0036] In this embodiment, both ends of the second screw rod 15 are fixedly connected with a clamping plate 22 , and the clamping plate 22 is movably connected to the clamping slot.

[0037] During specific use, the second screw 15 can extend or retract from the rotating drum 14 to drive the card plate 22 to move and make the card plate 22 detach from the card slot of the silicone rubber shell 3 or insert the card plate 22 into the card slot. When the card plate 22 is detached from the card slot, the silicone rubber shell 3 can be removed for maintenance or replacement.

[0038] Working principle: In use, the silicone rubber shell 3 adopts silicone rubber material with good insulation effect. When the silicone rubber shell 3 is sleeved on the outer surface of the cabinet 1, the cabinet 1 can be insulated, and the outer surface of the fixed block 10 is provided with a second insulating layer. When the cabinet door 11 is closed, the second magnetic strip 12 is magnetically attracted to the first magnetic strip 9 on the insulating frame 8, and the cabinet door 11 is isolated from the cabinet 1 under the action of the insulating frame 8. While the cabinet door 11 is protected from electric shock, the cabinet 1 can also be protected from electric shock to prevent the staff from touching the cabinet 1 or opening the cabinet door 11 due to leakage inside the cabinet 1 and getting an electric shock. When rotating, the rotating drum 14 can perform a threaded motion with the second screw 15, thereby driving the movement of the second screw 15. The setting of the top block 16 can limit the fixing rod 17. When the second screw 15 and the rotating drum 14 perform a threaded motion, the second screw 15 can be limited due to the sliding connection between the fixing rod 17 and the top block 16, so that when the rotating drum 14 and The threaded movement of the second screw 15 can drive the two second screws 15 to extend from or retract from the rotating cylinder 14. When the second screw 15 can extend from or retract from the rotating cylinder 14, it can drive the card plate 22 to move and make the card plate 22 disengage from the card slot of the silicone rubber shell 3 or insert the card plate 22 into the card slot. When the card plate 22 is disengaged from the card slot, the silicone rubber shell 3 can be removed for maintenance or replacement. When the meshing wheel 18 is rotated, it can be threaded with the first screw 6. Since the sliding movement of the first screw 6 and the through groove 5 limits the first screw 6, when the meshing wheel 18 and the first screw 6 are threaded, the first screw 6 can extend from the fixed cylinder 4 or retract and drive the top frame 7 to move up and down, so that the silicone rubber shell 3 can be sleeved on the outer surface of the cabinet 1 or be separated from the cabinet 1. The heat in the cabinet 1 can be discharged through the heat dissipation holes 20 and the round holes 19. The provision of the dustproof net 21 can prevent dust and the like from entering the cabinet 1 and affecting the operation of the internal electrical components.
