架空线

Catenary algorithm is regarded as a theory which is much close to the truth in cableway design. But it's very inconvenient for the application of engineering because it belongs to surpass function, especially in the past when the computer is unpopular.

在架空索道的设计中，悬链线理论是人们公认的最接近真实情况的设计理论，但是由于悬链线函数属超越函数，计算上的困难使其在工程应用中极为不便，尤其在计算机不甚普及的过去。

Seeing that many researchers devoted themselves to the study of catenary method in recent years. Based on the standard curve of the catenary, the catenary algorithm of two-end-fixed cableway was studied in this paper, which established state coordinate equation and which used the numerical value method to analyze non-linear equations under the condition offeree equilibrium and condition of deformation compatibility.

为此，近年来不少学者致力于单跨架空索道悬链线理论的研究，本文在此基础上，从索道悬链线的标准线形出发，通过建立状态协调方程，来研究架空索道的悬链线精确算法，计算上采用满足力平衡和变形相容条件为基础的数值分析方法来求解非线性方程组。

At last, the goal is that devices between the field level and the baylevel is easy to interlink,in spite of voltage being l0KV or 500KV insPitC of GlS or trolly wire being used, in spite of oPtical voltage/currenttransducer or combined voltage/current sensors being used in the field level, in spite of devices produced by ABB or GEC being used, in case that the interface scheme (including adopting which kind of network and standard) between the field level and the bay level is confirmed.

最终要达到这样一个目的，一旦过程层与间隔层的接口方案确定（包括确定使用何种网络、依据哪一个标准），那么不管系统电压是10KV还是500KV，不管是GIS还是架空线，不管过程层使用的是组合式电压/电流传感器还是光纤电压/电流互感器，不管过程层使用的是ABB的设备还是GEC的设备，过程层的设备就可以同间隔层的设备很容易地实现互连。
