阐述了电缆分布电容基本原理及其在工程应用中的危害,并通过对实际工程案例的分析来加深对其产生和相关影响的理解。对最远敷设距离进行了理论上的计算,得出了可用于指导工程设计的简单公式。最后提供了几种解决方法,并逐一进行了分析和比较以指导在实际工作中的应用。
The basic principle of cable distributed capacitance and its harm in engineering application are expounded. And the understanding of its generation and related influence is deepened through the analysis of actual engineering cases. The theoretical calculation of the furthest laying distance has been made and a simple formula that can be used to guide engineering design has been obtained. Finally, several solutions are provided and analyzed and compared one by one to guide the application in practical work.
