Problems solved by technology

In addition, because overhead cables are generally used for high-voltage lines, even if there is no direct contact with high-voltage lines in the high-voltage range, people may get electric shock if they are only close to high-voltage lines.
However, operators in the power supply department often need to work under high-voltage lines, especially sometimes they need to climb to the height of the tower for operation. Safety is at risk, especially during severe weather, such as a thunderstorm, where the risk of electric shock is higher

Embodiment 1

[0037] Such as Figure 1-Figure 2 As shown, the present embodiment provides a protection device, including a shield 1 , a support frame, a fixing part and a grounding component 4 . The support frame includes an upper support frame 21 and a lower support frame 22. The upper support frame 21 is arranged on the shield 1, and the lower support frame 22 is rotatably connected to the upper support frame 21. The support frame is configured to expand the shield 1 to form an umbrella. shape structure. The fixing part includes a first fixing part 31 and a second fixing part 32, the shielding part 1 is connected to the first fixing part 31, the lower support frame 22 is rotatably connected to the second fixing part 32, the first fixing part 31 and the second fixing part 32 All can be detachably fixed on the pole 5 . The grounding component 4 is detachably connected to the first fixing portion 31 . By setting the protection device to isolate the workers from the dangerous distance of t...

Embodiment 2

[0049] This embodiment discloses a protection device. The difference between the protection device in this embodiment and the protection device in Embodiment 1 is that the two ends of the first fixing part 31 are connected by snap buttons, and the first fixing part 31 The two ends of 31 are provided with a series of concealed buckles to match the poles 5 of different diameters. Of course, in order to ensure that the first fixing part 31 fits closer to the poles 5, elastic bands and elastic bands are also arranged on the first fixing part 31. The co-arrangement with the snap button can completely satisfy the matching between the first fixing part 31 and the poles 5 with different diameters. Further, the connection method of the two ends of the second fixing part 32 is the same as that of the first fixing part 31 , which is also connected by snap buttons, and the second fixing part 32 is also provided with an elastic band.

[0050] Apart from that, the rest of the structure of t...

Abstract

The invention relates to the technical field of power equipment, and discloses a protection device. The protection device comprises a shielding piece, a supporting frame, a fixing part and a groundingassembly. The supporting frame comprises an upper supporting frame body and a lower supporting frame body, the upper supporting frame body is arranged on the shielding piece, the lower supporting frame body is rotationally connected to the upper supporting frame body, and the supporting frame body is configured to open the shielding piece to form an umbrella-shaped structure; the fixing part comprises a first fixing part and a second fixing part, the shielding piece is connected to the first fixing part, the lower supporting frame body is rotatably connected to the second fixing part, and thefirst fixing part and the second fixing part can be detachably fixed to an electric pole; the grounding assembly is detachably connected to the first fixing part. By arranging the protection device,an operator is blocked outside the dangerous range of the overhead line, so that the operator can be prevented from suffering from an electric shock risk, and the operator can be shaded in sunny daysand sheltered from rain in rainy days.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a protection device. Background technique [0002] Electricity is the most important technology for social development and transformation at present. However, when electric power is transmitted, it will attenuate with the increase of distance. Therefore, in order to reduce this attenuation, at the beginning of electric energy transmission, high-voltage transmission will be adopted. [0003] As a transmission line for transmitting electric energy, overhead lines are generally bare metal conductors without insulation. They are erected in the air through concrete poles and towers. In addition, because overhead cables are generally used for high-voltage lines, even if there is no direct contact with high-voltage lines in the high-voltage range, just being close to high-voltage lines may cause electric shock. However, the operators in the power supply department often need...
