Description

Waterproof sealing device for cable connector for power engineering Technical Field The utility model relates to a waterproof sealing device for a cable joint for power engineering. Background In power engineering, waterproof sealing of cable joints is a key link for ensuring safe and stable operation of a power system. The cable joint is usually exposed in the outdoor or humid environment, if the waterproof sealing performance is insufficient, external pollutants such as moisture, dust and the like easily invade the interior of the joint, so that the problems of reduced insulating performance, short circuit, corrosion and the like are caused, and even fire or power interruption can be caused in severe cases, so that great economic loss and safety accidents are caused. The traditional waterproof sealing mode of the cable joint mostly adopts methods such as rubber sealing rings, heat-shrinkable sleeves or adhesive tape winding. Although these methods can meet the waterproof requirement to some extent, there are some disadvantages: The rubber sealing ring is easy to age and deform after long-term use, so that the sealing performance is reduced, the requirement on the skill of operators is high during installation, and the sealing effect is greatly influenced by human factors. The heat-shrinkable sleeve needs to be heated for construction, is complex to operate, and can shrink unevenly or crack under the extreme temperature environment, thereby influencing the sealing effect. The adhesive tape is wound, the waterproof performance is limited, the adhesive tape is easy to fall off or lose viscosity after long-term use, and the waterproof requirement under the complex environment is difficult to deal with. In addition, with the expansion of the scale of power engineering and the diversification of cabling environments, the requirements on the waterproof sealing device of the cable joint are also increasing. The existing waterproof sealing technology is difficult to meet the requirements of high reliability, long service life and easy installation and maintenance.
