Abstract

The invention discloses a power transmission multi-cable assembly device constituted by conductive joints and sheath pipes. Each of the sheath pipe is constituted by a pipe wall and a differentiation separation board, and the differentiation separation board is connected with the inner surface of the pipe wall, and can be used to divide the inner cavity of each of the sheath pipes into at least two wire passing cavities having the same areas of the cross sections. The conductive joints are parallely connected by connecting lugs, the number of which are equal to the number of the wire cavities, and are disposed on an insulation pedestal. Each of the connecting lugs is constituted by a connecting tongue and a socketed pipe, and the connecting tongue is additionally provided with at least one connecting screw hole, and the inner surface of each of the socketed pipes is uniformly provided with cone-shaped fastening teeth. The use method comprises four steps: determining of total wire diameter, differentiation of cables, assembly, and wiring. The use requirements of the large-cross section cables requiring various diameters can be flexibly and easily satisfied, and the production costs of the large-cross section cables can be reduced. The problem of the frequent occurrence of the skin effect of the large-cross section cables can be effectively solved, and therefore the use performance of the power cables can be greatly improved.

Description

technical field

[0001] The invention relates to a multi-cable assembly device for power transmission and a method for using it, belonging to the technical field of power transmission. Background technique

[0002] The diameter of the power cable directly affects the payload capacity that the power cable can bear. Generally speaking, the larger the diameter of the power cable, the greater the power load it can bear. In order to minimize the power in the Loss in the transmission process. At present, in the transmission of electric energy, the most commonly used method of electric energy transmission is the use of high-voltage AC transmission. When using this method to transmit electric energy, the electric energy carried by the power cable is in a periodical alternation according to a specific frequency. state, and when the alternating current passes through the conductor, the current will concentrate on the surface of the conductor, resulting in a skin effect, and this phenom...
