High-voltage cable joint protection device and method

Abstract

The invention discloses a high-voltage cable joint protection device and method. The device comprises an upper housing and a lower housing; one side of the lower end of the upper housing is provided with a mounting head; one side of the upper end of the lower housing is provided with a mounting seat; the mounting head is rotatably connected with the mounting seat; and the upper housing and the lower housing are provided with a mounting assembly, a dismounting assembly and a sealing assembly. During use, the upper housing can be directly buckled on the lower housing without screws, and an elastic bag can be automatically inflated to expand and cling to the surface of a cable in the mounting process, so that a closed space is formed in the upper housing and the lower housing, and dust and water are prevented from entering the upper housing and the lower housing through gaps to cause danger, the sealing performance of the device is ensured; and meanwhile, when the device needs to be disassembled, a user only needs to pull a pull ring, so that the upper housing and the lower housing can be automatically bounced off and separated, air in the elastic bag automatically returns to a cavity, the elastic bag is separated from the cable, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable protection, in particular to a high-voltage cable joint protection device and method. Background technique [0002] High-voltage cables are an important part of the power system, the main purpose is to transmit energy, and its operating voltage can be 10kV-500kV. Due to limited transportation conditions, high-voltage cables can only be made into reels with a length of about 800-1000 meters. The weak link, so the cable joint protection box is generally used to protect the cable joint. [0003] Generally, the upper and lower shells of the protective box are connected and fixed by screws, but when disassembling the protective box, the staff need to spend a lot of time to disassemble the screws, which will greatly reduce the work efficiency of the staff. At the same time, the general protective box is sealed The safety is poor, and water and dust can easily enter the protective box, which...

Problems solved by technology

[0003] Generally, the upper and lower shells of the protective box are connected and fixed by screws, but when disassembling the protective box, the staff need to spend a lot of time to disassemble the screws, which will greatly reduce the work efficiency of the staff. At the same time, the general protective box is sealed Poor performance, water and dust can easily enter the protective box, and there are likely to be safety hazards, which is very inconvenient to use
