Description

Technical Field

[0001] The utility model relates to the technical field of a high-voltage line isolation sheath, in particular to a high-voltage line isolation sheath. Background Art

[0002] The stability and sustainability of transmission lines are extremely important for power supply, so it is necessary to effectively maintain the normal operation of the lines. There are many factors that interfere with transmission lines. In the air, the main factor is bird damage. For example, when birds spread their wings and fly, they may touch different high-voltage lines, causing phase-to-phase short circuits or single-phase grounding faults, which can easily cause the line to trip, causing serious safety hazards to the surrounding environment and affecting the normal operation of the line.

[0003] After searching, it was found that a high-voltage line isolation sheath for bird protection was disclosed in the Chinese patent with authorization announcement 202221967037.8, including a first insulating honeycomb sleeve and a second insulating honeycomb sleeve. The first insulating honeycomb sleeve and the second insulating honeycomb sleeve have the same composition structure, and the outer walls of the first insulating honeycomb sleeve and the second insulating honeycomb sleeve are fixedly installed with rubber needle rods, the left end outer surfaces of the first insulating honeycomb sleeve and the second insulating honeycomb sleeve are fixedly installed with a second end plate, and the right end outer surfaces of the first insulating honeycomb sleeve and the second insulating honeycomb sleeve are fixedly installed with a first end plate. The utility model discloses a high-voltage line isolation sheath for bird protection, through the insulating honeycomb sleeve, the high-voltage line passes through the interior of the insulating honeycomb sleeve, and the outer wall of the insulating honeycomb sleeve is provided with a rubber needle rod.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] The high-voltage line of the high-voltage line isolation sheath for bird protection passes through the inside of the insulating honeycomb sleeve. When the device is installed, it needs to be threaded from one end of the high-voltage line, which is not convenient during installation. The setting of the plug block makes it impossible to move when installed with the second fixed block. After the high-voltage line is erected, the middle part is in a drooping state due to gravity, and the high-voltage line in the air will swing at a certain angle with the wind, which cannot be achieved by installing the plug block and the second fixed block.
