Problems solved by technology

[0002] Substation refers to the place where the voltage and current are transformed, received and distributed in the power system. The electrical equipment in the substation is divided into primary equipment and secondary equipment; at present, the secondary equipment protection screen of the substation contains multiple devices; Patrol inspection means that the staff on duty observe whether there is any abnormality in the appearance of the equipment through regular inspections, such as whether there is any change in color, whether there are sundries, whether the needle indication is normal, whether the sound of the equipment is normal, whether there is any abnormal smell, and the equipment that is allowed to be touched Whether the temperature is normal, measuring the change of the operating parameters of the electrical equipment during operation, etc., to judge whether the operating condition of the equipment is normal, but usually the operation object is part of the device, and it is very likely that the operation will be accidentally touched (moved) during the operation. Other irrelevant devices, pressure plates, etc. in the same screen cabinet, resulting in safety accidents

Embodiment 1

[0033] refer to Figure 1~3 , this embodiment provides a substation anti-misoperation device, including a shielding unit 100, a telescopic unit 200, and a fastening unit 300. The shielding unit 100 is suitable for any device in any protective screen cabinet in an electrical place. 200 to adjust the area that can be covered, wherein the shielding unit 100 is preferably made of transparent material, which does not affect the observation of non-operating devices. At the same time, it is provided with warning signs, which have a warning function. points, and the device is easy to install and strong.

[0034]Specifically, the shielding unit 100 includes a first shielding member 101 and a second shielding member 102. The first shielding member 101 and the second shielding member 102 can be combined into a cube with an opening on one side. The first shielding member 101 is divided into first U The groove 101a and the first baffle 101b, the first baffle 101b is connected to one end o...

Embodiment 2

[0040] refer to Figure 1-10 , is the second embodiment of the present invention, which is based on the previous embodiment, and differs from the previous embodiment in that: according to the above embodiment, the shielding unit 100 is connected to the device to be shielded by magnets.

[0041] Specifically, the end of the first baffle 101b connected to the notch of the first U-shaped groove 101a is connected with a first magnet 103, and the first magnet 103 is a bar magnet, which can be adhered to the first baffle 101b with glue. The end that the second baffle plate 102b is connected with the notch of the second U-shaped groove 102a is connected with a second magnet 104. Similarly, the second magnet 104 is a bar magnet, which can be adhered to the first baffle plate 101b with glue. Like this, Both the first magnet 103 and the second magnet 104 are adsorbed on the metal surface, so that the shielding unit 100 can be fixed on the equipment installation surface.
