Problems solved by technology

[0004] At present, the surface of the cable outside is often frostbitten or even damaged in relatively cold weather. In the prior art, antifreeze is usually added to the surface of the cable, but due to the loss of the antifreeze during use, and Can be easily washed out by water, so it will still reduce the service life of the cable

Abstract

The invention discloses an anti-freezing cable based on oil-filled wrinkles and a use method of the anti-freezing cable, and belongs to the technical field of cable protection. According to the anti-freezing cable based on the oil-filled wrinkles and the using method thereof, the external temperature of the cable is reduced, thus a memory alloy cladding is promoted to recover to a low-temperatureeasily-deformed phase state, and magnetic bulges wrapped by the memory alloy cladding are exposed; and the attraction effect of the magnetic bulges on a first magnet ring is utilized to pull a telescopic sliding barrel to move downwards, therefore, heat preservation oil in a hemispherical outer frame pushes the rubber sealing sheet open and then enters a gap between the hemispherical outer frame and a rubber outer wrapping film. On one hand, an ice layer outside the cable can be promoted to crack; on the other hand, the surface of a lotus leaf can be simulated by virtue of the convex deformation of the rubber outer wrapping film, the hydrophobicity of the surface of the cable is improved, an ice layer is promoted to fall off, water remaining on the surface of the cable is reduced, and theload of the cable is reduced, so that the possibility that the cable is crushed is reduced.

Description

technical field [0001] The invention relates to the technical field of cable protection, in particular to an antifreeze cable based on oil-filled folds and its application method. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors, etc. There are serious defects in the planned maintenance system adopted by most of the power equipment in the power system, such as frequent temporary maintenance, insufficient maintenance or excessive maintenance, blind maintenance, etc., which makes countries in the world spend a lot of money on equipment maintenance every year. How to reasonably arrange the maintenance of power equipment, save maintenance costs, reduce maintenance costs, and at...
