Abstract
The invention relates to a variable-frequency special wire cable which comprises at least one conducting material core, wherein an insulating layer is coated outside the conducting material core, anda poor conducting material liner core or hollow core is arranged in the conducting material core. The invention has the advantages that the cost of power transmission lines and the loss of power transmission are reduced.
Description
Technical field
The present invention relates to a kind of variable-frequency special wire cable, belong to technical field of electric wires and cables.
Background technology
The following frequency of the 400HZ that frequency control accesses is the envelope of the high carrier wave of KHZ level.Be illustrated in figure 1 as conventional electric wire.Shown in Figure 1A, be the single core cable cable of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2; Shown in Figure 1B, be a kind of form of the triple core wire cable of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2, forms three cores that are triangularly arranged, and wraps up a layer insulating 2 outside three cores again; Shown in Fig. 1 C, be three core flat cables of routine, its structure is at conductive material layer 1 outer wrapping insulating barrier 2, forms three and is horizontal core, wraps up a layer insulating 2 outside three cores again; Shown in Fig. 1 D, be another form of the triple core wire cable of routine, its structure is a direct wrap insulate layer 2 outside the conductive material layer 1 of three rounded distributions.For the electric wire of above-mentioned several forms, the carrier wave of KHZ level even tens KHZ levels can cause the very high skin effect that drives, thereby 5% droop loss (routine) that the frequency control power transmission line is allowed has dropped to 2% (frequency conversion), when promptly the conductor cross-section of frequency conversion power transmission line must be conventional control 2.5 times of identical ampacity.
Summary of the invention
The purpose of this invention is to provide a kind of electric wire that reduces power transmission line cost and transmission loss.
In order to achieve the above object, technical scheme of the present invention provides a kind of variable-frequency special wire cable, is wrapped with insulating barrier at the electric conducting material core, it is characterized in that, is provided with non-good electric conducting material lining core or hollow at the electric conducting material in-core.
The present invention reduces the transmission of electricity cost by the skin effect that drives of current delivery process.Advantage of the present invention is: reduced power transmission line cost and transmission loss.
