Abstract
The invention relates to a power cable used for ships and warships, and provides a design method for a degaussing cable with high heat conduction and low temperature rise used for ships and warships.An insulating material with high heat conduction (low heat resistance) coefficients and a jacket material are adopted, so that the prepared cable has relatively high heat conduction capacity and relatively low temperature rise compared with a traditional cable under same current load. Therefore, through the technical scheme adopted in the invention, according to the degaussing cable with high heatconduction and low temperature rise used for ships and warships and the manufacturing method thereof, the degaussing cable comprises a cable conductor, a high heat conduction ethylene propylene rubber insulating layer, a high heat conduction chlorosulphonated polyethylene jacket layer, an insulating layer and a jacket surface which is a cable surface from inside to outside in sequence; a thermocouple is installed on the surface of the cable to measure the temperature condition of the cable surface; a temperature measuring sensor is installed at the position of the cable conductor; and the thermocouple is installed for measuring the temperature condition of the cable insulating layer. The degaussing cable is mainly applied to the design and manufacturing of power cables used for ships andwarships.
Description
technical field [0001] The invention relates to a power cable for ships, in particular to a high-thermal-conductivity low-rise degaussing cable for ships, and specifically relates to a design method for a high-thermal-conduction low-rise degaussing cable for ships. Background technique [0002] Ships made of steel will generate an induced magnetic field under the action of the geomagnetic field during navigation, making them easy targets for magnetic detection equipment. In order to improve the magnetic protection capability of ships, eliminate the influence of magnetized ships on the accuracy of instruments and weapons, and ensure the safety and effectiveness of ship navigation, modern ships adopt degaussing measures to weaken the magnetic field strength of ships and improve their distribution characteristics. In the comprehensive degaussing service of large ships, a large current load will pass through the degaussing cable, and the short-term load may reach thousands of am...
