technical field

The invention relates to electric power equipment, in particular to electric power equipment suitable for humid environments, and belongs to the field of electric power.

Background technique

At present, power equipment has been applied to various fields. Especially cables, signal lines, etc. have more and more uses, and their installation places are also getting wider and wider. The humid environment is a big killer for power equipment. It not only easily leads to corrosion and failure of the equipment due to the humid environment, but also causes special difficulties in the installation and fixing of the equipment, which is significantly different from installation in factories, homes and other conventional places.

Hydrophobicity is a key factor for the long-term reliable operation of electrical equipment, especially cables. In addition to being eroded by liquid water and gaseous water, power equipment in a humid environment is also subject to the adhesion of organisms in a humid environment. These organisms are corrosive to substances, resulting in damage to the external protective layer/film/shell destroy. Therefore, it is necessary to carry out a more reasonable design on the structure of the power equipment, and to carry out special treatment on them, especially on their surfaces.

The fixed installation of power equipment in a humid environment is even more of a challenge, mainly because: all types of connectors in a humid environment will be eroded by liquid water, gaseous water, and the adhesion of organisms; more importantly, the humid environment Under the environment, there are often situations where the fixed position is unstable, such as muddy ground, flowing water on the surface, river beaches, seabed, and so on. Such an installation environment is difficult to deal with with conventional installation parts. Thereby need to design a kind of brand-new fixture that adapts to this new environment.
